St Louis County Property Appraiser: Records Search

The St Louis County property appraiser works to fix the value of every parcel of land in our local area. This task happens so that every homeowner pays a fair share of taxes. The office looks at many houses and buildings to see what they are worth in the current market. Every two years, the team checks the prices of homes that sold nearby. They use these sales to decide the value of your own house. This cycle is part of a plan to keep tax records up to date. You can find the main office in Clayton, where experts handle records for thousands of properties. Knowing how these values work helps you manage your home costs better each year.

Local tax laws in Missouri require this work to stay open and clear for everyone. People often look for the St Louis County property appraiser when they want to check their tax bill. The office does not set the tax rate itself. Instead, they find the market value of the land. Other groups like schools and fire districts set the rates that apply to those values. If you own a home in St. Louis County, you will get a notice in the mail about your home value. Keeping an eye on these notices is a smart way to stay ahead of your taxes. You have the right to look at the data the office uses to value your land at any time.

What Does the St Louis County Assessor Do?

The office head is Jake Zimmerman, who leads the team in finding the value of all real estate. They look at over 400,000 parcels of land across the whole county. Their job is to make sure the data stays correct and matches the law. They do not collect the cash for taxes. Their only goal is to find the right value for each property based on facts. They use maps, sale records, and building permits to do this work. Every person in the county relies on this data for school funding and road repairs. The office must follow strict rules set by the state of Missouri to keep things fair.

Fair Market Valuation of Real Property

Fair market value is the price a buyer would pay to a seller on the open market. The St Louis County property appraiser looks at three main ways to find this price. First, they look at recent sales of similar homes in your neighborhood. This is the most common way for houses. Second, they look at how much it would cost to build the house again from scratch. They subtract the age of the house from that cost. Third, for big stores or offices, they look at how much rent the building makes. These methods help them get as close as possible to the real world price of your land.

Maintaining Parcel Data, Ownership & Legal Records

The office keeps a huge list of every piece of land in the county. Each piece has a unique parcel number that acts like a name tag. They track who owns the land and where the boundary lines sit. If you sell your house, the office updates these records to show the new owner. They also keep track of legal descriptions which describe the land in detail. This data is vital for banks when they give out home loans. You can find these records online to see the history of your own property. It shows when the house was built and any changes made over the years.

Residential, Commercial & Agricultural Property Classification

Properties are put into different groups based on how they are used. This grouping is key because each group pays a different tax rate. Residential land is where people live, like houses or apartments. Commercial land is for businesses like shops and factories. Agricultural land is for farms and growing food. The law sets a percentage for each group. For example, residential property is taxed at 19 percent of its value. Commercial land is higher at 32 percent. Agricultural land is lower at only 12 percent. The office makes sure every building is in the right group so taxes stay fair.

Property Tax Assessment Role vs Treasurer & Recorder

It is easy to get these offices mixed up, but they do different things. The Assessor finds the value of the property. The Collector of Revenue or Treasurer is the one who sends the bill and takes the money. The Recorder of Deeds is the place where you file your house title after a sale. Think of the Assessor as the one who measures the land and the Collector as the one who takes the payment. These offices work together but stay separate to keep checks and balances. If you have a question about your value, call the Assessor. If you have a question about paying the bill, call the Collector.

State Compliance and KingProperty Tax Law

The state of Missouri has very strict rules for how counties value land. These rules are found in the Missouri Revised Statutes, Chapter 137. The St Louis County property appraiser must follow these laws every single day. The state checks the work of the county office to make sure they are not valuing homes too high or too low. If the county fails these checks, the state can step in and fix the numbers. This ensures that a house in St. Louis is valued using the same basic rules as a house in another county. It keeps the whole state system working well for every taxpayer.

St Louis County Property Search & Records Lookup

Finding data about a house is easy with the online tools provided by the county. You can use these tools to see what your neighbors paid for their homes. Investors use this data to find new projects to buy. Homeowners use it to check if their own records are correct. The online database stays open 24 hours a day for anyone to use. It contains a wealth of facts about land size, building age, and past values. Using the search tool is the fastest way to get the facts you need without calling the office.

Ways to Search Property Records

There are three main ways to look up a house in the county system. Each way helps you find the same record but uses different facts to start. You can pick the one that is easiest for you based on the data you have. Most people use the address because it is easy to remember. Others use the parcel ID if they have their tax bill nearby. The system is fast and shows results in just a few seconds. Here are the ways you can start your search today.

Search by Owner Name

You can type in the last name and first name of a person to see what they own. This is helpful if you want to find all the lots owned by a single person or company. Keep in mind that some owners use a company name instead of their own name. If a person has a very common name, you might see many results. You will need to look at the addresses to find the right one. This search is a public right and helps keep the market open and honest for everyone.

Search by Parcel Number

The parcel number is a long string of digits that never changes for that lot. It is often called a locator number in St. Louis County. This is the most accurate way to find a record. It skips all the names and addresses and goes straight to the specific lot. You can find this number on your yearly tax statement or your deed. Using this number prevents any mistakes that might happen with similar street names. It is the best way for pros like realtors and lawyers to find data.

Search by Property Address

Searching by address is the way most people find records. You just type in the street number and the name of the street. You do not need to add the city or zip code in most cases. The system will give you a list of matches to pick from. Make sure you spell the street name correctly to get the best result. If the house is a condo, you might need to add the unit number as well. This tool makes it simple to see data for any house you see while driving around the neighborhood.

What Information You Can Find

Once you click on a property, you will see a page full of data. This page is a snapshot of everything the county knows about that land. It includes the physical traits of the house and the financial history. You can see how the value has gone up or down over the last ten years. This data helps you see if your taxes are in line with the rest of the street. It also helps you see if there are any errors in the county records that need fixing.

Assessed Value & Legal Description

The page shows the market value and the assessed value. The market value is what the county thinks the house would sell for. The assessed value is 19 percent of that number for houses. You will also see the legal description. This is a technical way of describing where the land sits in a specific block or subdivision. It mentions the lot number and the book and page where the deed is kept. This part is very important for making sure the tax bill matches the right piece of dirt.

Ownership History & Sale Data

The system lists the current owner and often shows when they bought the house. It shows the sale price and the date the deed was signed. This history is great for seeing how the value of the land has grown over time. You can see if the house has sold many times or if the same family has owned it for years. If a sale was between family members for a low price, the system might mark it as a non-market sale. This helps keep those low prices from messing up the average values in the area.

Property Use Code & Zoning

Every lot has a use code that tells the county what the building is for. It might say “Single Family” or “Multi-Family” or “Vacant Land.” There is also data about zoning. Zoning tells you what you are allowed to build on the land. For example, some areas only allow houses while others allow small shops. Knowing the zoning is key if you plan to add a garage or a second floor to your home. It also shows the size of the lot in square feet or acres.

Accessing the Official St Louis County Property Search Tool

The official tool is found on the St. Louis County website. Look for the section labeled “Assessor” or “Real Estate Search.” It is free for everyone to use and does not require a login. The site works on computers and phones so you can use it anywhere. The data is updated often to show new sales and changes in ownership. This is the only place to get the official facts that the county uses for tax bills. Avoid third-party sites that might have old or wrong data about your home.

Common Issues With Property Lookups

Sometimes you might not find what you are looking for right away. A common issue is a misspelled street name. Another issue is that new houses might not be in the system yet. If a big piece of land was just split into smaller lots, it might take time for the new parcel numbers to show up. If you look up a house and the owner name is wrong, it might be because the deed was just filed. It can take a few weeks for the Assessor to get the new deed data from the Recorder of Deeds. If you have trouble, the office staff can help you find the right record over the phone.

Understanding Property Values in St Louis County

Property values are the base for your taxes, so it pays to know how they work. The county uses a mass appraisal system to value thousands of homes at once. They do not walk through every single house every year. Instead, they use computer models and data from recent sales. These models look at things like square footage, the number of bathrooms, and the age of the building. Your value can change even if you did not make any changes to your home. This happens because the market around you is always moving up or down.

Full Cash Value vs Limited Property Value

Full cash value is what the St Louis County property appraiser thinks the home is worth if sold today. In some places, there are limits on how much this value can grow each year to protect owners. However, Missouri law focuses on the fair market value as the main point. The goal is to keep the value on the books close to the real world price. If the market goes up 10 percent, your full cash value might go up too. This keeps the tax system fair so that people with more expensive homes pay a higher share of the costs.

Assessed Value vs Taxable Value

The assessed value is only a part of the market value. For a house, it is 19 percent. If your home is worth 200,000 dollars, your assessed value is 38,000 dollars. This lower number is what the tax rates are applied to. The taxable value is the final number used to calculate your bill after any exemptions are taken off. If you have a special tax break, your taxable value will be lower than your assessed value. Most people look at the big market value number first, but the assessed value is what really drives the cost of your taxes.

How Property Values Are Calculated

The St Louis County property appraiser uses a few steps to find your value. First, they divide the county into neighborhoods with similar homes. Next, they look at all the sales that happened in those areas over the last two years. They use these sales to create a price per square foot for the area. Then, they apply that price to your home. They adjust the price for things that make your home better or worse than the average. For example, a finished basement or a new roof might add to the value. A house in poor shape might see a lower value.

Why Your Property Value Changed This Year

Values change for two main reasons. The first is a change in the real estate market. If many people want to live in your town, prices go up. The second reason is a change to the physical building. If you add a room or a deck, the county will find out through building permits. They will then increase your value to match the new size. Values can also go down if the market slows or if a building is damaged. Every two years, the county does a full refresh to make sure everyone is paying based on current market facts.

Annual Valuation Timeline

The valuation work follows a strict calendar every year. On January 1st, the county sets the value for that tax year. This is called the valuation date. In the spring of odd-numbered years, the office sends out notices of change in value. You get these in late April or May. You then have until the second Monday in July to talk to the office if you think the value is wrong. This is the window for appeals. After July, the values are set, and the tax bills are created in the fall for payment in December.

Property Taxes in St Louis County

Paying property taxes is how we fund our local schools, parks, and police. In St. Louis County, these taxes are based on the value of your land and the rates set by local groups. Your bill might look long because it has many different items on it. Each item is for a different service in your specific area. People in one city might pay a different rate than people in the next city over. This is because they have different school districts or fire departments. The St Louis County property appraiser provides the value, but your neighbors and local boards decide the rates.

How Property Taxes Are Calculated

The math for your tax bill is simple once you know the steps. You start with the market value of your home. You multiply that by 19 percent to get the assessed value. Then, you divide that number by 100. Finally, you multiply it by the total tax rate for your area. For example, if the rate is 7.00 per 100 dollars of assessed value, and your assessed value is 40,000 dollars, you do 400 times 7. This gives you a bill of 2,800 dollars. Knowing this math helps you see how a small change in value can change your yearly bill.

Role of Tax Rates and Jurisdictions

A jurisdiction is a group that has the power to tax you. This includes the county government, your city, your school district, and the library. Each group sets a rate based on their budget needs for the year. Sometimes voters go to the polls to raise or lower these rates. The Assessor does not control these rates. If your taxes go up but your home value stays the same, it means a local group raised their rate. You can see a full list of these rates on the website of the Collector of Revenue. This shows exactly where every dollar of your tax money goes.

Where to View the Property Tax Roll

The property tax roll is the list of all taxes owed for every lot. You can view this data through the Collector of Revenue search tool. It shows if taxes were paid in past years and how much is owed for the current year. This is public data, so anyone can see it. It is very helpful when buying a home because you can see if the seller is behind on their taxes. It also shows the history of the tax rates in that specific spot. You can access this roll online without needing to go to the courthouse in person.

Estimating Your Annual Property Taxes

If you are thinking of buying a house, you should estimate the taxes first. Look at the current market price and use the 19 percent rule to find the assessed value. Then, look up the tax rate for that specific address. Rates in St. Louis County often fall between 6 and 10 percent of the assessed value. A quick way to guess is to take 1.5 to 2 percent of the market price for the yearly bill. This helps you plan your monthly house payment, which often includes taxes and insurance. Being ready for this cost prevents surprises later on.

Understanding Your Valuation Notice

The valuation notice is a paper that tells you the new value of your home. It is not a bill. It shows the old value and the new value side by side. It also tells you how to start an appeal if you disagree with the new number. Many people ignore this notice and then get upset when the bill arrives in November. You must read this notice as soon as it arrives. It is your only chance to fix a high value before the taxes are set for the year. Look closely at the “Reason for Change” section to see why they moved your value.

Exemptions & Property Tax Relief Programs

There are ways to lower your tax bill through special programs called exemptions. These programs are for people who meet certain rules, like seniors or veterans. Some programs freeze your value so it does not go up as you get older. These tax breaks are not automatic. You have to apply for them and show proof that you qualify. The St Louis County property appraiser helps manage these applications to make sure only the right people get the breaks. Taking the time to apply can save you hundreds or even thousands of dollars over time.

Primary Residence (Homeowner) Exemptions

In Missouri, there is a program called the Property Tax Credit or “Circuit Breaker.” This helps seniors and people with disabilities pay their taxes. It is for people who own and live in their home as their main residence. To get this, your income must be below a certain level. The state looks at how much you pay in taxes versus how much money you make. If you qualify, you get a credit back on your taxes. This program helps people stay in their homes even if the values in the area go up quickly.

Senior, Veteran & Disability Exemptions

Special help is available for those who served in the military or have a permanent disability. Disabled veterans might be able to get a full or partial break on their taxes. Seniors over the age of 62 can look into the “Senior Tax Freeze.” This new program in St. Louis County aims to stop the tax bill from growing for eligible seniors. You must own your home and meet the age rule. This is a big help for those on a fixed income who worry about rising costs in their neighborhood. Check the county website for the latest rules on these breaks.

Agricultural Classification Benefits

If you have land that is used for farming, you can get a much lower tax rate. As mentioned, agricultural land is assessed at only 12 percent of its value. Also, the value is based on how much the land can produce, not what it would sell for to a developer. This keeps farms from being taxed out of existence. To get this, you must show that the land is actually being used for crops or livestock. The office may visit the land to check. This is a key way the county supports local food growth and open green spaces.

How to Apply for Exemptions

To get a tax break, you must fill out a form from the Assessor or the state. Most forms are available online to print out. You can also pick them up at the office in Clayton. You will need to fill in your personal details and your parcel number. Some forms need to be signed in front of a notary. Once you send it in, the office will review it and let you know if you are approved. It is best to apply early in the year to make sure the break shows up on your next bill. If you miss the date, you might have to wait until next year.

Required Documentation & Deadlines

Each program needs different proof. For age-based breaks, you need a birth certificate or ID. For disability breaks, you need a letter from a doctor or the Social Security office. For veteran breaks, you need your discharge papers. Income-based programs will ask for your tax returns from the last year. Most of these applications are due by June or July. The “Senior Tax Freeze” has its own specific dates that change, so watch the news for updates. Keeping your papers organized makes the application easy and fast.

St Louis County GIS Maps & Parcel Viewer

The GIS map tool is a digital map that shows every lot in the county. GIS stands for Geographic Information System. It is like Google Maps but with extra layers of data about land. You can see where your property lines are and how big your yard is. It also shows things like flood zones and city boundaries. This tool is free and works in any web browser. It is a powerful way to see the county from above and learn about the land around you. Many people use it to see the shape of a lot before they go to visit it.

What the Parcel Viewer Shows

When you open the parcel viewer, you see a map with lines drawn around every house. If you click on a lot, a box pops up with data. This box shows the owner, the address, and the parcel number. You can also see the size of the land in acres. The viewer allows you to switch between a regular map and a photo from a plane. These photos are very clear and show buildings, trees, and pools. It is a great way to see how a neighborhood has changed over the years by looking at older photos.

Using GIS Maps for Property Research

Researching a home is better when you can see it on a map. You can see if a house is near a busy road or a park. You can also measure the distance between the house and the property line. This is helpful if you want to build a fence or a shed. The map tool has a “measure” button that lets you draw lines and find distances. You can also see the elevation of the land to see if it is on a hill or in a low spot. This data is vital for anyone planning to build something new on their land.

Zoning, Land Use & Boundary Layers

The GIS tool has different layers you can turn on and off. One layer shows zoning, which tells you what the land can be used for. Another layer shows school district lines, so you know exactly which school your kids would attend. There are also layers for sewers, water lines, and electric paths. Seeing these boundaries helps you see why your taxes might be different from someone just one street over. It also shows the limits of cities and the county. This is helpful for knowing who to call for trash pickup or road snow removal.

GIS Tools for Buyers, Investors & Professionals

Pros use the GIS map every day to do their jobs. Realtors use it to show clients the lot size and area traits. Real estate investors use it to find vacant land or houses that might be good for a flip. Engineers use the map to plan for new roads or pipes. The tool allows you to export data into lists or prints. You can even search for all the houses sold in a certain area over the last year. This high level of data makes the St. Louis County real estate market more open and easier for everyone to work in.

Tangible Personal Property (Business Property)

Taxes are not just for land and buildings. In Missouri, you also pay taxes on “tangible personal property.” For most people, this means their cars, trucks, and boats. For businesses, it means the tools and machines they use to work. This type of property is valued every year, not every two years. You must tell the county what you own on January 1st of each year. The St Louis County property appraiser then decides the value of those items based on their age and type. Paying these taxes is required to get your car tags renewed each year.

What Qualifies as Business Personal Property

Businesses must pay taxes on everything they use that is not part of the building. This includes desks, chairs, computers, and copy machines. It also includes big things like tractors, factory machines, and medical tools. If you own a restaurant, your ovens and tables are personal property. Even things like signs and decor count. Small tools that cost very little might not need to be listed. The county provides a list to help business owners know what to include. Keeping good records of what you buy for your business makes this task much easier.

Who Is Required to File

Every person and business in St. Louis County must file a personal property list. If you own a car, the county usually gets that data from the state. But if you are a business owner, you must send in a form yourself. This applies to big corporations and small one-person shops. Even if you work from home, you might need to file if you have business equipment. If you do not own any property in the county, you should still let them know so they do not send you a bill by mistake. Filing on time keeps you in good standing with the local government.

Filing Deadlines and Online Submission

The deadline to file your personal property list is March 1st of each year. The county sends out forms in January to give you plenty of time. You can mail the paper form back or use the online filing tool. The online tool is faster and gives you a receipt right away. If you file online, the system remembers what you had last year. You just have to add new things or remove things you sold. This saves a lot of time for business owners who have the same equipment for many years.

Valuation Method and Common Mistakes

The value of personal property is based on the original cost and how old it is. The county uses a “depreciation schedule” to lower the value as things get older. For example, a five-year-old computer is worth much less than a new one. A common mistake is not listing the year an item was bought. Another mistake is forgetting to tell the county when you sell an item. If you do not tell them, you will keep getting a bill for it. Always double-check your list before you hit the submit button to ensure the data is right.

Penalties for Late or Missing Filings

If you miss the March 1st deadline, you will have to pay a penalty. The penalty is a percentage of your tax bill, and it grows the later you are. In some cases, the county might guess what you own if you do not tell them. This guess is usually higher than the real value, which means you pay more in taxes. It is much better to file even if you are a few days late. Also, you cannot get your car license plates if you have unpaid personal property taxes. This is why most people make sure to pay this bill on time every December.

Property Valuation Appeals & Corrections

If you think the St Louis County property appraiser has valued your home too high, you can fight it. This is called an appeal. Every homeowner has the right to show evidence that their home is worth less than the county says. The appeal process is set up to be fair and gives you a chance to speak to a board. You do not need a lawyer to do this, though some people choose to hire one. Most appeals are settled by looking at photos and sale prices of other homes. It is a key part of making sure the tax system stays accurate for everyone.

When You Can Appeal Your Property Value

You can only appeal during a specific time each year. This window opens after you get your valuation notice in the spring. The deadline to file is the second Monday in July. You cannot appeal your taxes in December when the bill arrives. By then, it is too late. You are appealing the value, not the tax rate. If you missed the July date, you have to wait until the next year to try again. This is why it is so important to check your mail in May and June for that notice from the Assessor.

How to File an Appeal in St Louis County

The first step is to talk to the Assessor’s office informally. Sometimes they can fix a simple error without a full hearing. If that does not work, you file a formal appeal with the Board of Equalization (BOE). You can do this online or by mail. You will need to fill out a form and explain why you think the value is wrong. You then get a date for a hearing. At the hearing, you show your facts to a group of three people. They will listen to you and to the Assessor and then make a choice on the value.

Evidence That Supports a Strong Appeal

To win an appeal, you need facts. Simply saying “my taxes are too high” will not work. You should bring photos of any damage to your home, like a cracked foundation or an old roof. You should also bring a list of recent sales in your neighborhood. Look for houses that are like yours but sold for less than your county value. An appraisal from an independent professional is the strongest evidence you can have. The board likes to see clear data that shows your home would not sell for the price the county has on record.

Appeal Deadlines and Review Process

After you file your appeal by the July deadline, the board starts their review. Hearings happen throughout the summer and fall. You will get a notice in the mail with your hearing date. You can choose to go in person or have the board look at your papers without you. After the hearing, the board sends a letter with their decision. If you still disagree, you can appeal further to the Missouri State Tax Commission. Most cases are solved at the county level. The process is designed to be finished before the final tax bills go out in November.

Public Records, Transparency & Accountability

The work of the St Louis County property appraiser is open to the public. This transparency keeps the office honest and helps people trust the system. You can see how much your neighbors pay and how the county arrived at those numbers. This openness is a core part of our local government. The office must follow state laws about public records. They also undergo audits to make sure they are using the right methods. Accountability means that if a mistake is made, there is a clear way to get it fixed for the homeowner.

Public Access to Property Records

Public access is provided through the online search tools and the office in Clayton. You do not need a special reason to look at these records. You can see the history of any parcel in the county. This includes the building size, the age, and the last few sale prices. This data is used by reporters, researchers, and regular people every day. It helps everyone see the trends in the real estate market. Being able to see this data for free is a major benefit for all residents of St. Louis County.

Requesting Official Assessor Documents

If you need a certified copy of a record, you can request it from the office. This might be needed for a legal case or a bank loan. There might be a small fee for printing and certifying these papers. You can also request data in bulk if you are doing a big project. For most people, the printout from the website is all they need. If you cannot find a specific document, the staff at the counter can help you. They can look up old records that might not be on the website yet.

Data Accuracy, Audits & Oversight

The county takes many steps to make sure the data is correct. They use computer checks to find values that look too high or too low. They also send teams out to look at houses from the street. The State Tax Commission audits the county every two years. They look at a sample of homes to see if the values match the real market. If the county is off by too much, they must change their ways. This oversight ensures that the St Louis County property appraiser stays on track and follows the law.

Legal Authority of the Assessor’s Office

The power of the Assessor comes from the Missouri Constitution and state law. They have the legal right to value property and to ask for data about sales. They must stay neutral and not favor any one person or group. Their job is not to be popular but to be accurate. They follow the rules set by the state legislature. This legal base gives the office the weight it needs to do its job. It also gives the public a clear set of rules to follow when they have questions or complaints about their values.

Important Dates for St Louis County Property Owners

Marking your calendar with these dates will save you from stress and late fees. The tax year in St. Louis County moves in a steady cycle. Knowing when to expect mail and when to file forms is a big part of being a homeowner. Most of these dates are the same every year. Some dates might move a day or two if they fall on a weekend. Staying alert during the spring and the end of the year is most important. Here are the key times you need to remember.

January 1 – Valuation Date

This is the most important day for the St Louis County property appraiser. The value of your home on this exact day is what determines your taxes for the year. If your house burns down on January 2nd, you still owe taxes on the full value for that year. If you buy a new car on January 2nd, you do not owe personal property taxes on it until the next year. This “snapshot” date makes it clear for everyone. It is the starting point for all the work the office does for the next twelve months.

February–March – Valuation Notices Mailed

During odd-numbered years, the county sends out notices if your home value has changed. You should look for these in your mailbox during this time. The notice gives you the new market value and your new assessed value. This is the best time to review the data for errors. Check the square footage and the number of rooms. If the notice shows a huge jump in value, you should start gathering your evidence for an appeal right away. Do not wait until the summer to start your research.

Appeal Filing Deadlines

The deadline to file an appeal with the Board of Equalization is always the second Monday in July. This is a hard deadline. If you miss it, the board cannot hear your case. You can mail your appeal, but it must be postmarked by this date. Filing online is safer because you get a time stamp. Many people wait until the last minute, so the office can be very busy in early July. It is much better to get your appeal in early so you have time to fix any mistakes on the form.

Exemption Application Cutoff

If you want a tax break for the current year, you usually need to apply by late spring or early summer. Some programs, like the senior tax freeze, have their own specific sign-up windows. These dates can change based on new local laws. Always check the Assessor’s website in January to see the current deadlines. If you miss the cutoff, your tax break will not start until the following year. Being early ensures that your November tax bill shows the lower amount you deserve.

Business Property Reporting Deadlines

Business owners must file their personal property lists by March 1st. This is a firm date set by Missouri law. If you are a new business, you must register with the Assessor so they know to send you a form. If you close your business, you must tell the office so they stop billing you. Missing this date leads to penalties that can add up quickly. Most business owners find it easiest to file online in January or February while they are doing their other business taxes.

Contact the St Louis County Assessor’s Office
