The state and sometimes the local government.
The Feds get 18.3 cents per gallon on gasoline and the states grab their share. Most people wouldn't consider that a sales tax since it say $3.95 / gallon at the pump. It isn't as blatant as buying a $3.95 loaf of bread at the market and finding out it really costs $4.15. One is considered an excise tax, the other a sales tax like the terminology makes a difference.
One exception to a state sales tax is marijuana. Recreation marijuana has a 20% tax, medical 4%. I think this county adds 3% for recreational. The last ballot split recreational/medical. The recreational initiative passed and the medical failed.
