Missouri Trade-In Sales Tax Credit in Hazelwood, MO
How Missouri's trade-in tax credit cuts your taxable price at a Hazelwood dealership — the statute, the math, the 180-day rule, and what to bring.
In Missouri, sales tax on a vehicle purchase is calculated only on the portion of the price that exceeds your trade-in allowance, under Mo. Rev. Stat. § 144.025. At Missouri's 4.225% state rate — plus local sales tax layered on top — a $10,000 trade on a $30,000 used car means you pay tax on $20,000, not $30,000. If your trade (plus any manufacturer rebate) equals or exceeds the purchase price, you owe no sales tax at all.
How does the Missouri trade-in tax credit work when buying a used car in Hazelwood, MO?
Under Mo. Rev. Stat. § 144.025, Missouri computes vehicle sales or use tax only on the purchase price that exceeds the actual trade-in allowance, as long as a bill of sale or other record documents that allowance. The credit applies whether you trade at a Hazelwood dealership like Bommarito Nissan Hazelwood or sell your vehicle privately within a 180-day window. The Department of Revenue collects the tax when you title the vehicle.
The statutory mechanism, in plain English
The taxable base is reduced, not the tax rate. Missouri's state sales and use tax rate is 4.225 percent, and that rate (plus any applicable city and county tax) is applied to the net figure after the trade-in allowance comes off. The statute has been on the books in its current form for several years.
How much does a trade-in actually save a Hazelwood buyer in sales tax?
At the 4.225% state rate, every $1,000 of trade-in allowance removes roughly $42.25 from the state portion of your sales tax bill — before local tax is added. Local rates vary by city and county in Missouri and are imposed in addition to the state rate.
A worked example on a used Rogue
Say you're buying a pre-owned Nissan Rogue priced at $25,000 and trading a vehicle Bommarito Nissan Hazelwood appraises at $10,000. Under § 144.025, Missouri tax is calculated on $15,000, not $25,000. If the Rogue is new instead, the 2026 Nissan Rogue, starting at $29,690 (as of October 2026) would be the entry point to the current model year — and the same statute reduces the taxable base by whatever trade allowance appears on your bill of sale.
Trade-in math at common price points
| Vehicle Price | Trade-In Allowance | Taxable Base | State Tax (4.225%) |
|---|---|---|---|
| $20,000 | $5,000 | $15,000 | $633.75 |
| $25,000 | $10,000 | $15,000 | $633.75 |
| $30,000 | $15,000 | $15,000 | $633.75 |
| $35,000 | $35,000+ | $0 | $0 |
If the trade-in allowance plus any applicable rebate equals or exceeds the purchase price, Missouri owes no sales or use tax on the transaction. Local sales tax applies on top of the state figures shown and should be verified against the Hazelwood rate in effect at titling.
Trading in at the dealership vs. selling privately — which saves more in Missouri?
A dealer trade applies the Missouri trade-in credit automatically on the buyer's order. A private sale can still earn the credit under Missouri's 180-day rule: if you sell your old vehicle separately and buy (or contract to buy) a replacement within 180 days before or after that sale, you can claim the tax reduction by filing DOR Form 426 with supporting documentation.
The 180-day credit, in practice
Form 426 is used to request a 180-Day Credit when a buyer purchased, or contracted to purchase, a unit and sold a different unit within 180 days before or after the purchase. To claim it, you must submit a properly completed and signed Bill of Sale (Form 1957) or Notice of Sale (Form 5049) for the unit that was sold, along with the title receipt for the unit you bought. If the subsequent vehicle is titled more than 180 days after the sale, the allowance is still permitted if you can establish the purchase or contract was finalized before the 180-day period expired.
Why trading at a Hazelwood dealer is usually simpler
With a dealer trade, the allowance is documented on the buyer's order, the tax is computed on the net at titling, and there's no refund paperwork to chase. Bommarito Nissan Hazelwood states it offers transparent pricing with no hidden fees, which keeps the trade allowance clearly separated from the sale price — exactly the line-item documentation § 144.025 requires. A private sale can net more on the trade in absolute dollars, but the tax savings and the Form 426 process are the hidden variables most sellers forget to run.
What documentation do Hazelwood buyers need to lock in the credit?
You need a bill of sale or other record showing the actual trade-in allowance; without it, Missouri will not reduce the taxable base. For a 180-day refund claim, bring all related bills of sale showing the paid sale prices to the department of revenue at the time of licensing. The traded article must also be one on which Missouri sales or use tax was previously paid, credited, satisfied, or exempted.
Timing matters: the 30-day titling window
Missouri requires buyers to title and pay sales tax on a newly purchased vehicle within 30 days of the purchase date. Miss that window and a $25 title penalty hits on the 31st day, increasing by another $25 for every 30 days late, up to a maximum of $200.
What local Hazelwood factors change the math?
Missouri's 4.225% state rate is only the starting point — city and county sales taxes in the Hazelwood area are imposed in addition to the state rate, and the trade-in reduction applies against both. Buyers commuting into Hazelwood from surrounding counties or across the river should expect to pay tax based on their home jurisdiction's rate when they title, not the dealership's. Rebates work the same way: where a buyer receives a rebate from the seller or manufacturer, sales tax is computed on the price that exceeds the rebate, provided the bill of sale documents it.
A note on recent customer experience
Great place to purchase new and used car. I bought used car Nissan Rogue 2023 model. I found sale price is good at this store comapre to market. Edward "cowboy" was very helpful and polite during whole conversation, and promptly reply everytime.
Clear documentation of the sale price — the same documentation Missouri law requires for the trade-in credit — is what makes the tax math at titling match the deal you signed.
Frequently Asked Questions
Does Missouri tax a used car differently than a new car for the trade-in credit?
No. Missouri's trade-in credit statute applies the trade-in reduction to the taxable purchase price of a motor vehicle regardless of whether it is new or used. The 4.225% state rate, plus local tax, is computed on the price that exceeds your documented trade-in allowance either way. The traded vehicle must be one on which sales or use tax was previously paid, credited, satisfied, or exempted.
What if my trade-in is worth more than the car I'm buying?
Where the trade-in or exchange allowance plus any applicable rebate exceeds the purchase price of the purchased article, there shall be no sales or use tax owed under § 144.025. You still have to title the vehicle within 30 days and present the bills of sale showing the figures, but Missouri will not assess sales tax on a transaction where the credit zeroes out the taxable base.
How do I claim the Missouri 180-day credit if I sold my old car privately?
File DOR Form 426 with a Missouri Title Receipt for the vehicle you bought and a properly completed Bill of Sale (Form 1957) or Notice of Sale (Form 5049) for the vehicle you sold. The sale and purchase must fall within 180 days of each other, and all related bills of sale showing the paid sale prices must be presented to the department of revenue at the time of licensing.
What happens if I miss the 30-day titling deadline in Missouri?
Missouri assesses a $25 title penalty on the 31st day after purchase if you have not titled the vehicle. The penalty increases another $25 for every 30 days you are late, up to a maximum of $200. The Department of Revenue collects taxes when you apply for title regardless of the purchase date, so the sales tax itself does not go away — only the penalty grows.
Does the trade-in credit apply to local sales tax in Hazelwood too?
Yes. Missouri's state sales tax rate for motor vehicles is in addition to any local sales tax imposed by cities and counties, and the § 144.025 trade-in reduction applies to the taxable base used for both. Local rates vary by jurisdiction in the Hazelwood area and should be verified against your home address, since Missouri titles the vehicle at the buyer's residence rate — not the dealership's.
What if I return the vehicle after buying it?
Missouri DOR Form 426 may be used to request a refund in qualifying situations beyond the 180-day trade-in credit; if a return is being considered, consult the Department of Revenue for the applicable documentation requirements. The refund path is separate from the 180-day trade-in credit, with its own documentation requirements.
The bottom line for Hazelwood buyers
The Missouri trade-in tax credit is a real, statutory reduction in what you owe — not a dealership marketing line. On a mid-priced used car, it routinely saves hundreds of dollars in state tax alone, with additional savings on the local rate, and it can zero out the sales tax entirely when the trade allowance meets or exceeds the purchase price. The documentation matters: a clean bill of sale showing the trade-in allowance separately from the sale price is what the Department of Revenue needs at titling.
