Frequently Asked Questions
Where do I find my local sales tax rate?
Sales tax is set at the state level and often combined with county or city rates, so it varies by exact location. Check your state's department of revenue website for the current combined rate in your area.
Does this include both state and local tax?
Enter whatever combined rate applies where you are. This calculator just applies the percentage you enter — it doesn't look up rates for you.
