So you're a merchant who wants to charge someone a round dollar amount, but still pay sales tax? This app tells you what your base price would be at any sales tax percentage!
Or, maybe you just need to calculate sales tax amounts, and already know the base price. This does that too!
And remember, you should always double check the math!
