US Tax Calculators (2026)
Estimate your 2026 federal taxes as an employee, a freelancer, a small-business owner or a corporation. Each calculator uses the official 2026 figures published by the IRS and SSA — tax brackets, standard deductions, the Social Security wage base and more — and shows how the result was worked out.
These are estimates of federal tax only and not tax advice. Your actual tax depends on your full situation and on state and local taxes; confirm important decisions with a CPA or enrolled agent.
