The tax percentage calculator adds a percentage tax to a pre-tax price, or finds the pre-tax price when you know the total. Adding tax: Total = Pre-tax × (1 + Tax%/100). Finding pre-tax: Pre-tax = Total / (1 + Tax%/100).
Sales tax rates in the United States vary by state and locality. Common combined rates (state + local) include: California 10.25% (Los Angeles), New York 8.52% (NYC), Texas 8.25%, Florida 7–8%, Washington 10.4%, Illinois 10.25%. Always verify current rates with your state's revenue department.
You can also combine multiple tax rates: a product with 6% state tax and 2.5% county tax has a combined rate of 8.5%. Just add the individual rates and apply the combined rate once.
