What’s the Sales Tax??

Useless app. I wanted to know what the sales tax was on a purchase I was making in NYC. The app only tells you the state sales tax (4%) then you have to go online independently to see what the city tax is (4.75%) then you add them together to get what the sales tax is (8.75) then go back to this app and put in the percentage (8.75) to get your result. Basically it’s Simple calculator. Complete waste of money.

Rapid fire automatic ,


Waste of time and Your Money very incorrect
