Frequently Asked Questions

Which states have no car sales tax?

Five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Note: Alaska and Montana may have local sales taxes. Delaware charges a $100 documentary fee instead of sales tax.

Does a trade-in reduce sales tax?

In most states, yes — you only pay sales tax on the net price (new car price minus trade-in value). However, some states (California, Texas, and others) do NOT allow this tax break for private party trades. Check your state's specific rules.

What is the highest car sales tax state?

California has the highest base state sales tax at 7.25%. However, when including local taxes, Louisiana, Tennessee, and Arkansas can reach over 10% combined. South Carolina caps sales tax at $500 maximum — a huge savings for expensive car buyers.
