Frequently asked questions
How do I find my local sales tax rate? ▼
Sales tax = state rate + local (county/city) rate. For example, California's base rate is 7.25%, but cities can add up to 2.5% more, making effective rates up to 10.75%. Check your state's tax authority website or use the item's receipt.
Are all purchases taxable? ▼
No — many states exempt groceries, prescription drugs, and certain clothing. Services are often not taxed. Online purchases may or may not be taxed depending on whether the seller has nexus in your state.
Is sales tax deductible? ▼
Yes — if you itemize deductions on your federal tax return, you can deduct state and local sales taxes paid during the year (the SALT deduction, capped at $10,000). Keep receipts for large purchases.
Note: State rates shown are base rates only. Local surcharges may apply. Always verify current rates with your local tax authority.
