Common questions

What is the sales tax rate in Seattle?

The combined rate in Seattle is 10.35%, stacking Washington's state tax with county, city, and district taxes. Special districts inside the metro can differ slightly; your receipt shows the exact rate applied.

How do I remove tax from a receipt total?

Switch to "Remove tax" mode and enter the total. The math divides by 1.103 — dividing the total by 1 + the rate — which correctly backs the tax out.

Do online purchases charge this rate?

Generally yes — since the 2018 Wayfair decision, most online retailers collect sales tax based on your delivery address, so shipped-to-home orders typically carry your local combined rate.
