Accuracy of Calculators and Rates
SmallBizCalc's calculators use standard accounting and finance formulas, and the tax rates and benchmarks behind them are drawn from public sources such as the IRS, BLS, SBA, and state agencies. Tax law, fees, and rates change frequently, and published rates can lag real-world changes or omit local nuances. Results are planning estimates, not professional advice. You are solely responsible for verifying any figure that influences a legal, tax, financial, or similarly consequential decision, confirm with the official source or a qualified professional before acting.

Calculators, Guides, and Editorial Role
SmallBizCalc pairs interactive calculators with plain-language guides, explainers, and state comparisons. The calculator formulas follow standard accounting and finance methods; the rates and benchmarks they rely on come from the public sources named in our methodology.

Governing Law and Disputes
These terms are governed by the laws of the United States and the jurisdiction in which SmallBizCalc is domiciled, without regard to conflict-of-law principles. Any dispute arising from or relating to your use of SmallBizCalc will first be addressed through good-faith informal negotiation.

Nothing in these terms limits your statutory consumer-protection rights under applicable local law.
