You found the car, signed the title, and got to the license office, and the clerk asked for a personal property tax receipt you have never seen. In Missouri you cannot get plates without last year’s paid receipt or a waiver from your county. Here is which one you need in St. Louis County, St. Louis City, or St. Charles County, how to get it fast, and roughly what the tax will cost.

The short answer: To register a car in the St. Louis area you need last year’s paid personal property tax receipt (two years for a two-year plate) or a statement of non-assessment, called a waiver, from the county or City of St. Louis where you lived on January 1. Cars are assessed at one third of their average trade-in value, and City of St. Louis bills are due December 31.

Key takeaways
- No receipt, no plates: Missouri requires a paid receipt for the prior tax year, or a waiver, before it will register or renew a car.
- January 1 decides everything: you owe tax for a year if you owned the vehicle on January 1 of that year.
- Waiver if you had no car: new Missouri residents and people who owned no vehicle on January 1 of last year get a statement of non-assessment instead.
- Right office: the waiver comes from the assessor in the county (or the City of St. Louis) where you lived on January 1, not where you live now.
- How the tax is figured: one third of the car’s average trade-in value, times your local levy rate.
- Due date: City of St. Louis bills are mailed in November and due December 31. Pay on time so next year’s renewal is easy.
Why do you need a personal property tax receipt to get plates in Missouri?
Missouri ties car registration to local property tax. Under RSMo 301.025, an application to register a vehicle must include a tax receipt for the tax year right before the year of registration, or a statement certified by the collector that no tax was due. The Department of Revenue renewal page spells it out:
- One-year plates: a paid receipt for the previous year.
- Two-year plates: paid receipts for the previous two years.
- Receipt format: the original, a copy, or an electronic copy, as long as it is legible.
- No tax owed: a statement of non-assessment from your county of residence or the City of St. Louis.
The DOR help page adds that the receipt must be in one of the owners’ names, list each vehicle you own, and be marked paid. A statement of non-assessment cannot be checked online, so bring the paper copy.
This is the same step that trips people up in our Missouri title transfer guide: the title can go through, but plates wait on the tax paperwork.
Do you need a receipt or a waiver?
It depends on where you lived and what you owned on January 1 of last year. This table follows the State Tax Commission and county assessor rules.
| Your situation | What to bring | Where to get it |
|---|---|---|
| You owned a car in the same county on January 1 last year | Last year’s paid receipt | Your county collector, or the City of St. Louis Collector |
| You owned no vehicle on January 1 last year (first car) | Statement of non-assessment (waiver) | The assessor where you lived on January 1 |
| You moved to Missouri from another state | Waiver, with your title or out-of-state registration | The assessor where you live now |
| You moved within Missouri | Receipt or waiver from your old county | The county you lived in on January 1 |
| Leased vehicle | Receipt or waiver in the leasing company’s name, per DOR | Your lease company or the assessor |
| Active military, home of record not Missouri | Leave and Earnings Statement instead | Bring it to the license office |
Bought your first car this year? You still bring a waiver for last year now. Then, because you will own the car next January 1, you declare it, pay that bill by December 31, and use that receipt at your next renewal. Asking for a waiver also puts you on the assessment roll for the next tax year, according to the State Tax Commission.
Moving from out of state comes with other steps too, like the VIN inspection. See how to title an out-of-state car in Missouri.
How do you get a personal property tax waiver in St. Louis?
A waiver is free in the City and is issued by the assessor. Each office has its own process.
St. Louis County
The St. Louis County Assessor says you can visit an office, schedule an in-person or virtual appointment, or apply online. Bring one of these:
- New Missouri resident: the vehicle title in your name, your current out-of-state registration, or a Missouri DOR title receipt.
- First-time vehicle owner: the title filled out by buyer and seller with the date of sale, a Missouri title application, or a bill of sale signed by both with full vehicle details.
- Leased vehicle: the lease agreement or out-of-state registration.
- Did not live in the county on January 1: the county says to get your waiver from the county you lived in.
City of St. Louis
The City of St. Louis Assessor issues waivers to new Missouri residents and to people who did not own a vehicle on January 1 of the prior year and have no tax delinquency. There is no fee.
- In person: at City Hall, with your title or bill of sale and a photo ID. Register for the office’s Virtual Lobby first.
- By email: send a copy of your license, each title front and back, your registration or renewal notice, and proof of your current address. City residents only.
- Timing: emailed requests are answered by mail through USPS, not by email, so allow time before your title deadline.
St. Charles County
In St. Charles County, the Assessor’s Office issues a Certificate of Non-Assessment if you did not own a vehicle in the county on January 1 of the required year. Use the online request form or go in person. First-time owners bring the signed title, a Form 108, or a bill of sale with the VIN. New residents bring the title or out-of-state registration. Leased cars need the lease or registration renewal notice. The county no longer issues these to military members, who register with a Leave and Earnings Statement.
How is personal property tax on a car calculated in Missouri?
Three rules from state law set the bill:
- 1. January 1 ownership. Under RSMo 137.075, whoever owns the vehicle on January 1 owes that year’s tax.
- 2. One third of value. Under RSMo 137.115, personal property is assessed at 33 1/3% of its true value.
- 3. Trade-in value. The assessor uses the average trade-in value from the current October issue of the guide the State Tax Commission picks, such as NADA. The City says its values come from NADA average trade-in.
Then your local levy rate, set by every taxing district where you live (school, fire, city, county), is applied to the assessed value per $100. That is why two neighbors in different school districts can pay different amounts for the same car.
A simple way to estimate it
Say your car’s average trade-in value is $9,000.
- Assessed value: $9,000 divided by 3 is $3,000.
- Per $100: $3,000 is 30 units of $100.
- Your tax: 30 times your combined levy rate. Each $1.00 of rate per $100 adds $30 to the bill.
Find your combined rate on last year’s bill or your county’s tax rate page. One 2026 change helps: for vehicles worth less than $50,000 as of January 1, 2025, RSMo 137.115 now says the assessor cannot assess the car higher than the prior year’s assessment, if it was properly assessed then.
Personal property tax is separate from the sales tax you pay when you title the car. For that number, see our Missouri car sales tax rates for St. Louis.

How do you pay or find your St. Louis personal property tax receipt?
In the City, the Collector of Revenue mails bills in November and taxes are due by December 31. A balance on January 1 is subject to penalty and interest.
- Pay online: through PayIt St. Louis by card (2.45% convenience fee) or ACH ($1.25 fee).
- Pay in person, by mail, or by phone: receipts for in-person and mailed payments arrive by mail within about ten business days.
- Print a receipt: the City’s tax receipt lookup lets you search by address, name, or account number and print a receipt for each year paid.
- Lost a receipt elsewhere: DOR says to contact your county collector. Some counties let a license office check your records.
If you are not sure which office to call, the State Tax Commission directory lists every county assessor and collector.
Do you pay personal property tax on a car in Illinois?
No. The Illinois Constitution required the state to abolish all ad valorem personal property taxes by January 1, 1979. If you live in the Metro East, there is no county car tax receipt to bring for plates. You title and register through the Illinois Secretary of State instead, which our Illinois title transfer guide walks through.
If you move from Illinois to Missouri, you are a new resident, so you get a Missouri waiver from the assessor where you now live.
What if you need to drive the car before plates?
Missouri gives you 30 days after you buy a car to apply for title. Under RSMo 301.190, the late penalty is $25 for the first 30 days late and $25 for each 30 days after, up to $200. Order your waiver the day you buy, since mailed waivers can take days. A Missouri temporary tag covers the gap while paperwork catches up.
In the St. Louis area you will likely also need an emissions test, and older or high-mileage cars need a Missouri safety inspection. The City’s registration page says inspection notices must be no more than 60 days old.
