FAQ
What is the vehicle sales tax in Hawaii?
Hawaii charges a state-level rate of 4.00% on vehicle purchases. Local rates can add up to an additional 0.50%. Trade-in value is NOT deductible — tax applies to full purchase price.
Does Hawaii give a trade-in tax credit?
No. Hawaii taxes the full purchase price regardless of trade-in value. This is a meaningful negative for buyers — verify with the state DMV before factoring trade-in into your math.
What is the title transfer fee in Hawaii?
Hawaii charges approximately $5 for title transfer. Dealer documentation ("doc") fees typically range up to $295, though these are dealer-set and negotiable on most transactions.
How do I calculate out-the-door price in Hawaii?
Out-the-door = purchase price + (taxable amount × effective rate) + title fee + registration. Taxable amount equals purchase price minus trade-in (where allowed). Effective rate is state plus local. Use the calculator above for an exact figure on your specific purchase.
