Missouri Vehicle Registration Fee Calculator

Missouri is one of the few states that still bands registration by TAXABLE HORSEPOWER rather than weight or value. Per the Missouri Department of Revenue's official fee page, the annual fee is $18.25 under 12 taxable HP, $21.25 for 12–23, $24.25 for 24–35, $33.25 for 36–47, $39.25 for 48–59, $45.25 for 60–71, and $51.25 for 72 and above. Note that "taxable horsepower" is a calculated ALHP rating, not the engine output on a spec sheet. A separate registration processing fee of $9.00 (1-year) or $18.00 (2-year) applies — note that works out to the same $9 per year either way, so choosing the two-year term saves you a trip to the license office rather than money. Title costs $8.50 plus a $9.00 title processing fee. State sales tax is 4.225% with local rates added on top, and the trade-in allowance is deducted from the taxable price. Missouri also requires a paid county personal-property tax receipt before you can register — that is locally assessed, so this calculator leaves it at 0 until you supply your own figure instead of fabricating a statewide average.
