About TheCalculatorWeb

TheCalculatorWeb builds free, fast, and accurate financial calculators for the US market — starting with paycheck calculators for all 50 states, updated for the 2026 tax year.

Methodology

Every calculation runs on a single audited engine that applies the 2026 federal tax brackets and standard deduction (IRS Rev. Proc. 2025-32), FICA payroll taxes including the $184,500 Social Security wage base (SSA), and each state's own 2026 income tax rules — brackets, flat rates, deductions, and where significant, payroll programs like California SDI.

State data is sourced from each state's revenue authority and the Tax Foundation's 2026 survey, with the sources and modeling assumptions listed at the bottom of every page. Results are cross-checked against independent calculators to stay within a ±2% tolerance.

What we are not

These calculators provide estimates for planning and comparison. They are not tax, legal, or financial advice — for filing decisions, consult a qualified professional.
