Sales Tax on a Used Car From a Private Seller

Last updated: May 7, 2026

In 45 states plus DC, you pay state sales or use tax on a used car bought from a private seller — generally at the same rate that applies at a dealer. The buyer remits the tax at the DMV during registration, not to the seller. Five states (Alaska, Delaware, Montana, New Hampshire, Oregon) impose no general sales tax. The bill of sale is the basis; some states will substitute the higher of bill-of-sale price or NADA book value if the price looks artificially low. Family transfers between spouses or lineal relatives are typically exempt.

The basics

When you buy a used car from a dealer, the dealer collects sales tax at closing and remits it to the state. When you buy from a private seller, no business intermediary collects the tax — instead, you (the buyer) pay it directly at the DMV when you register the vehicle. The legal structure is technically a "use tax" rather than a sales tax in most states, but the rate is identical for vehicles. For most filers in most states the experience is the same: line item on the registration receipt, paid at the counter or online.

The rate is your home state's combined state + local sales tax rate applied to the bill-of-sale price (with caveats below). A New Yorker buying a $15,000 used car from a New Yorker pays NYC's combined 8.875% rate — $1,331 — at DMV. A Texan buying the same car from another Texan pays Texas's 6.25% standard motor vehicle tax — $937. The "private vs dealer" distinction generally does not matter for the rate; what matters is your home state's tax structure for vehicles.

5 no-sales-tax states

Five states impose no general state sales tax. A used car purchase in one of these states — whether from a dealer or private seller — incurs no state-level sales tax:

• Alaska — no state sales tax. Local boroughs may impose a small sales tax (1-7.5% in some areas), so a private sale in Anchorage is genuinely tax-free, while a sale in Juneau may carry a small borough tax.
• Delaware — no state sales tax, but Delaware imposes a 4.25% Document Fee on titled vehicles, which functions as a vehicle-purchase tax.
• Montana — no state sales tax. A handful of counties (Big Sky, West Yellowstone resort areas) impose a local "county option tax" of $5-$10, and luxury vehicles may carry a $87.50 registration surcharge in their first year.
• New Hampshire — no state sales tax on vehicles. Standard registration applies.
• Oregon — no state sales tax on vehicles. Oregon imposes a 0.5% privilege/use tax on new vehicles (Oregon Vehicle Privilege Tax) but the privilege tax does not apply to used vehicle purchases between private parties; only the registration fee applies.

These states are favored by buyers attempting tax avoidance through the so-called "Montana LLC" structure for high-value RVs and exotic cars. The risk lies in the buyer's home state, which may pursue use-tax evasion if the vehicle is garaged and driven primarily in the home state.

States with reduced or special structures

• Georgia — replaced sales tax on vehicles with a one-time Title Ad Valorem Tax (TAVT) in 2013. TAVT is 7.0% of fair market value for new and used vehicles bought from dealers and private parties (rate was 6.6% before 2024). Vehicles purchased before 2013 are still under the prior annual ad valorem regime. See our Georgia state page.
• North Carolina — uses a 3.0% Highway Use Tax (HUT) instead of standard sales tax on motor vehicles. Applied to bill-of-sale price for both dealer and private sales.
• Hawaii — General Excise Tax of 4-4.712% applies; lower than mainland sales taxes.
• South Carolina — caps the state vehicle sales tax at $500 (the "Infrastructure Maintenance Fee"). Buyers of $50k+ vehicles save substantially versus a percentage rate.
• Nevada — 6.85% basic state rate plus county add-ons; uses a depreciation schedule for the Government Services Tax assessed annually (separate from the sales tax at purchase).

State-by-state used-car tax rates

State sales/use tax rates applicable to private-party used-vehicle purchases. Local rates may apply on top in many states; figures below are state-level only.

Local rates can change quarterly; verify the current combined rate with your county tax assessor or state Department of Revenue before registration.

Bill-of-sale price vs fair market value

Most states use the bill-of-sale price as the tax basis. About 22 states cross-check against NADA / Kelley Blue Book values and substitute the higher number when the bill of sale shows an artificially low price. Among the cross-check states: Florida, Massachusetts, New York, North Carolina, Pennsylvania, Texas, Virginia, Wisconsin. The threshold for "artificially low" varies — some states trigger the substitution at 80% of book value, others at 60%.

Honest low prices (e.g., a beater sold cheap because of mechanical damage) usually pass scrutiny if the buyer can document the condition with photos, repair estimates, or a written statement from the seller. The DMV may also accept the lower price if the title is salvage or rebuilt. Writing a falsely low number to evade tax is sales-tax fraud and can carry penalties of 10-50% of the unpaid tax plus interest.

Dealer reporting vs private-sale buyer responsibility

At a dealer, the dealer is the tax-collection agent. The dealer reports the sale to the state, collects the tax, and remits within 30-60 days. If the dealer fails to collect or remit, the dealer (not the buyer) is on the hook. The buyer's tax obligation is satisfied at closing.

At a private sale, no agent collects the tax. The buyer is personally responsible for paying use tax at the DMV during registration. If the buyer never registers the vehicle (parks it as project car, or hides it, or registers it in a no-tax state), the state has no easy collection path. State revenue agencies cross-reference DMV title transfers with sales tax filings — if a title transferred to your name and no tax was collected, you may receive a delinquency notice. Some states share VIN data with the IRS and other state revenue agencies to identify multi-state evasion.

Out-of-state purchase scenario

You owe sales/use tax to your home state, not the seller's state. Most state revenue codes treat private out-of-state purchases as use-tax events: the vehicle "uses" your state's roads, and your state taxes it accordingly. The seller's state gets no tax (with limited exceptions for dealer transactions where the dealer collected tax for the seller's state).

If the seller's state happened to collect a sales tax (rare for private sales but possible), your home state typically gives credit for tax paid up to your home state's rate. Example: a NJ resident buys a $20,000 car from a private VA seller. VA does not collect on the sale. NJ collects 6.625% = $1,325 at registration. If the seller's state had collected, say, 4% = $800, NJ would give $800 credit and collect the $525 differential.

The cleanest approach for cross-state private sales: agree on the price, sign the bill of sale, and pay the tax in your home state at registration. See our out-of-state purchase guide for the full sequence.

Trade-in credit

Trade-in credit lets you deduct the value of a trade-in vehicle from the taxable basis. A buyer trading a $5,000 vehicle on a $20,000 purchase only pays sales tax on $15,000 — saving meaningfully in a high-tax state. Trade-in credit applies only to dealer transactions; private-party purchases do not qualify in any state.

Among states with generous trade-in credits at dealers: Texas, Missouri, Arizona, Iowa, Illinois (capped at $10k), Wisconsin (5% reduction), Colorado, Indiana. States that do not grant trade-in credit at dealers: California, District of Columbia, Hawaii, Kentucky, Maryland, Michigan (partial), Virginia (partial). For private buyers, trade-in is irrelevant.

Family transfer and gift exemptions

Most states exempt vehicle transfers between specific family members from sales/use tax. The standard list of exempt relationships:

• Spouses (current, not ex-spouses unless court-ordered)
• Parents and children (biological, adopted, step)
• Grandparents and grandchildren
• Siblings (in some states)

The mechanics: prepare a gift affidavit (most states publish a free form — Form FT-500 in Illinois, AT-2 in Connecticut, MV-13ST in Pennsylvania, etc.), file it with the title transfer at the DMV, and pay only the standard title and registration fees. The buyer pays no use tax. Federal gift tax may apply to the seller if the gift exceeds the annual exclusion ($19,000 in 2026 per IRS Rev. Proc. 2025-32) — see our gifted car registration guide.

Some states extend the exemption to nieces, nephews, aunts, uncles (rare), and in-laws (more common). Cousins are typically not exempt. Same-sex married couples are treated identically to opposite-sex married couples in all 50 states post-Obergefell. Domestic partners may qualify in CA, NV, OR, WA depending on registration with the state.

Worked examples — top 5 states

Sale price: $15,000 used Honda Civic, private-party purchase, no trade-in, no exemptions.

California

Combined rate Los Angeles County: 9.5% (state 7.25% + LA district 2.25%). Tax = $15,000 × 9.5% = $1,425. Plus California vehicle license fee (~$98 in year 1 for a $15k vehicle) and registration ($65 + smog $20). Total at DMV: roughly $1,608.

Texas

State motor vehicle tax: 6.25%. Tax = $15,000 × 6.25% = $937.50. Plus title fee $33, registration $51.75, inspection $7.50. Total: roughly $1,030. Texas has no county/city add-on for motor vehicle tax.

New York

NYC combined rate: 8.875% (state 4.0% + NYC 4.5% + MCTD 0.375%). Tax = $15,000 × 8.875% = $1,331. Plus title $50, registration $26-$140 by weight. NYC residents see roughly $1,440 total.

Florida

State rate 6.0% plus discretionary county surtax (Miami-Dade 1% on first $5,000). Tax in Miami-Dade = $15,000 × 6% + $5,000 × 1% = $900 + $50 = $950. Plus initial registration $225 (first-time FL resident only) and title $77.25. Total for first-time FL: roughly $1,252.

Georgia

TAVT 7.0% on fair market value (replaced annual ad valorem in 2013). Tax = $15,000 × 7% = $1,050 (one-time). No annual ad valorem tax thereafter — the major Georgia-vs-other-states distinction. Plus title $18 and registration $20.

Tax deductibility

Sales tax paid on a vehicle purchase may be deductible on your federal return on Schedule A — but only if you elect the optional state and local sales tax deduction instead of state income tax. Per IRS Publication 600 and the IRS sales-tax-deduction calculator, the SALT cap (currently $10,000 per household, scheduled to expire after 2025 unless Congress extends) limits the combined deduction. Vehicle sales tax is one of two specific items the IRS allows on top of the standard sales tax tables (the other is boats).

Note: this is the sales tax at purchase, NOT the annual registration fee. The registration fee deduction is separate and only the value-based portion qualifies. Most filers in income-tax states (CA, NY, MA, NJ, etc.) take the income tax deduction instead, making the sales tax deduction moot. In no-income-tax states (TX, FL, TN, NV, WA, SD, WY, AK, NH on most income), the sales tax deduction is the default and a vehicle purchase can meaningfully boost it.

Insurance for your newly-purchased car

Used or new, you need insurance before driving off — and most likely before registering. Comparison shop in advance:
