Overview
Miss it, and renewal simply won't go through - no plates, no sticker, until the collector's office confirms you paid. Below, estimate both pieces: the December property tax bill (which varies sharply by county and school/fire district) and the horsepower-based renewal fee itself, which is unrelated but due at the same visit.

Missouri renewal cost FAQ
Why won't Missouri let me renew my registration?
The most common reason is an unpaid personal property tax bill. License offices check your county's records before processing a renewal - no valid paid receipt (or non-assessment certificate if you owned nothing taxable) and the system blocks you, regardless of whether your registration fee itself is ready to pay.
I sold the car in March - why did I still get a tax bill for it?
Missouri personal property tax is based on what you owned on January 1 of that year, full stop. Selling, trading, or totaling the vehicle afterward doesn't remove that year's bill; you owe it to the county collector regardless.
How is my property tax bill actually calculated?
Your assessor pulls the vehicle's market value from the October NADA guide, assesses it at 33⅓% of that value, then applies your local levy (expressed per $100 of assessed value). A $15,000 car assessed at $5,000, taxed at a $7.50-per-$100 levy, owes $375 for the year.
Why is my neighbor's bill different from mine on a similar car?
Levies stack school district, fire district, library, county, and city rates, and those boundaries don't follow street grids evenly - two houses a block apart can sit in different school districts with meaningfully different combined levies.
What if I just moved to Missouri and have no prior tax history?
First-time Missouri vehicle owners get a non-assessment certificate from the county assessor instead of a paid-tax receipt, confirming you owed nothing the prior year because you weren't yet a resident. That certificate satisfies the renewal requirement the same way a receipt would.
Does the horsepower-based renewal fee change based on my tax bill?
No - the two are entirely separate systems. The county collector's tax bill is based on your vehicle's value and your local levy; the license office's renewal fee is fixed by your vehicle's taxable horsepower band and is identical statewide.
