SimpleTaxCalculator provides free, state-specific US tax calculators for sales tax, property tax, gas tax, capital gains, and inheritance tax — no signup or email required.
What is SimpleTaxCalculator?
SimpleTaxCalculator is a set of web-based tools that estimate US taxes based on your location and a few inputs. Each calculator asks for the relevant data (purchase amount, property assessed value, investment gain, etc.) and returns an instant breakdown of the total tax, including state and local rates. The site is maintained by a single real person who sources every rate directly from official state Department of Revenue websites and updates them quarterly.
Key Features
- Calculator suite — Five dedicated tools: Sales Tax Calculator (with county-level combined rates), Capital Gains Tax Calculator (for stocks, crypto, real estate), Gas Tax Calculator (per gallon and per fill-up), Property Tax Estimator (based on assessed value and mill rate), and Inheritance Tax Calculator (by state, estate value, and heir relationship).
- State-level precision — Rates cover all 50 US states; popular states (Ohio, Arizona, Pennsylvania, Florida, Texas, California) have dedicated sales tax pages with direct links.
- Official source transparency — Every rate is drawn from official state Department of Revenue websites, not third-party aggregators. Each tool page links to its source.
- Quarterly audits — All rates are reviewed every three months and updated within 48 hours of any published change by a state authority.
- No account required — No signup, no login, no email collection. Just select a state and get an instant estimate.
