How Sales Tax Works
The calculator works by taking your item's base price and multiplying it by the combined tax rate (expressed as a decimal). To get the final total, the resulting tax amount is added back to the original price.
According to Avalara, the most accurate way to calculate tax is by using address-level combined rates.

Frequently Asked Questions (FAQ)

Q: How do I find the original price if I know the total with tax?
A: Divide the total amount by (1 + tax rate as decimal). For example, if you paid $107 with a 7% tax rate, calculate $107 \u00f7 1.07 to find the $100 original price.
Q: Which states have no sales tax?
A: Five states currently have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon, though local taxes may still apply in Alaska.
Q: Is shipping and handling subject to sales tax?
A: This depends entirely on the state. Some states consider shipping a non-taxable service if separated on the invoice, while others tax it regardless.
