Missouri does not charge one flat rate. You pay the state rate plus the local rate for your home address, and in St. Louis that local piece changes a lot from one town to the next.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote rs-answer-box is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>The short answer:<\/strong> Missouri charges 4.225% state sales tax on a car, plus the local sales tax where you live, on the price minus any trade-in. In the St. Louis area that totals 9.679% in St. Louis City, 7.738% in unincorporated St. Louis County, and 5.95% in unincorporated St. Charles County. You pay it at the license office within 30 days of purchase.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\"><em>Updated October 6, 2026.

The Missouri Department of Revenue says the local tax applies \u201cif the address of the applicant is within a city or county\u201d on its chart. If you live inside city limits, the city rate applies. If you live outside any city, the county rate applies.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Where you live<\/th><th>Local rate<\/th><th>Total with 4.225% state<\/th><th>Tax on $4,000<\/th><th>Tax on $9,000<\/th><\/tr><\/thead><tbody><tr><td>St. Louis City<\/td><td>5.454%<\/td><td><strong>9.679%<\/strong><\/td><td>$387.16<\/td><td>$871.11<\/td><\/tr><tr><td>Unincorporated St. Louis County<\/td><td>3.513%<\/td><td><strong>7.738%<\/strong><\/td><td>$309.52<\/td><td>$696.42<\/td><\/tr><tr><td>Chesterfield<\/td><td>4.513%<\/td><td><strong>8.738%<\/strong><\/td><td>$349.52<\/td><td>$786.42<\/td><\/tr><tr><td>Florissant<\/td><td>4.763%<\/td><td><strong>8.988%<\/strong><\/td><td>$359.52<\/td><td>$808.92<\/td><\/tr><tr><td>Kirkwood<\/td><td>5.513%<\/td><td><strong>9.738%<\/strong><\/td><td>$389.52<\/td><td>$876.42<\/td><\/tr><tr><td>Unincorporated St. Charles County<\/td><td>1.725%<\/td><td><strong>5.950%<\/strong><\/td><td>$238.00<\/td><td>$535.50<\/td><\/tr><tr><td>St. Charles, O\u2019Fallon, St. Peters<\/td><td>3.725%<\/td><td><strong>7.950%<\/strong><\/td><td>$318.00<\/td><td>$715.50<\/td><\/tr><tr><td>Wentzville<\/td><td>4.225%<\/td><td><strong>8.450%<\/strong><\/td><td>$338.00<\/td><td>$760.50<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Local rates from the Missouri DOR Motor Vehicle Sales Tax Rate Chart (labeled July to September 2026).

Start with the purchase price<\/strong> on your bill of sale or invoice.<\/li>\n\n\n\n<li><strong>2. Subtract any trade-in allowance or rebate<\/strong> shown on your paperwork.<\/li>\n\n\n\n<li><strong>3. Add 4.225% to your local rate<\/strong> from the table above or the DOR calculator.<\/li>\n\n\n\n<li><strong>4. Multiply<\/strong> the taxable amount by that total rate.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-example-city\">Example 1: a $4,000 car, St. Louis City buyer<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">$4,000 x 9.679% = <strong>$387.16<\/strong> in sales tax. Add the $8.50 title fee and $9 processing fee and you pay $404.66 at the license office, before plates.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-example-county\">Example 2: a $9,000 car with a $2,000 trade-in, unincorporated St. Louis County<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">$9,000 minus $2,000 = $7,000 taxable. $7,000 x 7.738% = <strong>$541.66<\/strong>. Without the trade-in, the same car would cost $696.42 in tax, so the trade saves you $154.76.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tax is only one line. Before you bid, add up the whole cost, which we walk through in <a href=\"https:\/\/www.remarketspace.com\/blog\/top-5-mistakes-overpay-car-auctions\/\"><span class=\"has-inline-color has-secondary-color\">mistakes that make buyers overpay at car auctions<\/span><\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-trade-in\">Does a trade-in or selling your old car lower the tax?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, both can. Under <a href=\"https:\/\/revisor.mo.gov\/main\/OneSection.aspx?section=144.025\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><span class=\"has-inline-color has-secondary-color\">RSMo 144.025<\/span><\/a>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Trade-in:<\/strong> tax is figured only on the price above the trade-in allowance. If the trade-in plus any rebate is more than the price, no sales tax is owed.<\/li>\n\n\n\n<li><strong>Selling it yourself:<\/strong> the same credit applies if you sell your old vehicle and buy the next one within 180 days before or after that sale. Bring the bill of sale showing the price to the license office.<\/li>\n\n\n\n<li><strong>Rebates:<\/strong> a seller or manufacturer rebate comes off the taxable price if your paperwork shows it.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The 180-day rule matters for auction buyers. You usually cannot trade a car in at an auction, but you can sell your old car privately and still get the credit if the timing lines up.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-private-sale\">Do you pay sales tax on a private sale, a gift, or an auction car?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Private sale:<\/strong> yes. The DOR collects the tax when you apply for title, no matter who sold you the car.<\/li>\n\n\n\n<li><strong>Auction car:<\/strong> yes, the same way. You pay Missouri state and local tax on the purchase price when you title it.<\/li>\n\n\n\n<li><strong>Gift:<\/strong> the DOR has a separate process. The giver writes \u201cGIFT\u201d in the sale price area of the title (not $1) and you bring a General Affidavit (Form 768) or a written gift statement.

Tax applies to the purchase price minus any trade-in allowance or rebate, and you pay it when you title the car at a Missouri license office.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-2\"><strong class=\"schema-faq-question\">What is the car sales tax in St. Louis County?<\/strong> <p class=\"schema-faq-answer\">In unincorporated St. Louis County the total is 7.738%, which is 4.225% state plus 3.513% local. Cities inside the county add more. For example, Chesterfield totals 8.738%, Florissant 8.988%, and Kirkwood 9.738% on the Department of Revenue chart.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-3\"><strong class=\"schema-faq-question\">What is the car sales tax in St. Louis City?<\/strong> <p class=\"schema-faq-answer\">St. Louis City buyers pay 9.679% in total: 4.225% state tax plus 5.454% local tax. On a $4,000 car that is $387.16, and on a $9,000 car it is $871.11, before the $8.50 title fee and $9 processing fee.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-4\"><strong class=\"schema-faq-question\">Do you pay sales tax on a private car sale in Missouri?<\/strong> <p class=\"schema-faq-answer\">Yes. Missouri collects state and local sales tax when you apply for title, no matter if you bought from a dealer, an auction, or a private seller. You have 30 days from the purchase date to title the car and pay the tax.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-5\"><strong class=\"schema-faq-question\">Does a trade-in lower car sales tax in Missouri?<\/strong> <p class=\"schema-faq-answer\">Yes. Tax is figured only on the price above the trade-in allowance. If you sell your old vehicle yourself within 180 days before or after buying the new one, that sale price can also reduce the taxable amount if you bring the bill of sale.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-6\"><strong class=\"schema-faq-question\">What happens if I title my car late in Missouri?<\/strong> <p class=\"schema-faq-answer\">Missouri charges a $25 title penalty on the 31st day after purchase. It grows by another $25 for every 30 days you are late, up to a maximum of $200, on top of the sales tax you still owe.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-7\"><strong class=\"schema-faq-question\">Do Illinois residents pay Missouri tax on a car bought in St. Louis?<\/strong> <p class=\"schema-faq-answer\">Illinois residents report vehicle tax to the Illinois Department of Revenue. Use Form RUT-25 for a car bought from an out-of-state dealer or auction, or Form RUT-50 for a private-party purchase. Both are due within 30 days.<\/p> <\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-sources\">Sources<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/dor.mo.gov\/forms\/MV%20-%20Local%20Sales%20Tax.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><span class=\"has-inline-color has-secondary-color\">Missouri Department of Revenue: Motor Vehicle Sales Tax Rate Chart<\/span><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/dor.mo.gov\/pdf\/rates\/2026\/october2026.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><span class=\"has-inline-color has-secondary-color\">Missouri Department of Revenue: Sales and Use Tax Rate Tables, October to December 2026<\/span><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/sa.dor.mo.gov\/mv\/stc\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><span class=\"has-inline-color has-secondary-color\">Missouri Department of Revenue: Motor vehicle sales tax calculator<\/span><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/dor.mo.gov\/motor-vehicle\/titling-registration\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><span class=\"has-inline-color has-secondary-color\">Missouri Department of Revenue: Motor vehicle titling and registration<\/span><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/dor.mo.gov\/motor-vehicle\/titling-registration\/buying-vehicle.html\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><span class=\"has-inline-color has-secondary-color\">Missouri Department of Revenue: Buying a vehicle<\/span><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/dor.mo.gov\/motor-vehicle\/selling-a-vehicle.html\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><span class=\"has-inline-color has-secondary-color\">Missouri Department of Revenue: Selling and gifting a vehicle<\/span><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/revisor.mo.gov\/main\/OneSection.aspx?section=144.025\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><span class=\"has-inline-color has-secondary-color\">Revised Statutes of Missouri 144.025: Trade-ins, rebates, and the 180-day rule<\/span><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/dor.mo.gov\/driver-license\/law-changes\/documents\/2023MVDLLegislativeChanges.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><span class=\"has-inline-color has-secondary-color\">Missouri Department of Revenue: 2023 law changes, including SB 398 dealer tax collection<\/span><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/tax.illinois.gov\/individuals\/cars.html\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><span class=\"has-inline-color has-secondary-color\">Illinois Department of Revenue: Tax requirements for vehicles<\/span><\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\"><em>This guide is general information, not legal or tax advice.
