How This Calculator Works

Calculation methodology and assumptions

Freelance tax calculator for Arizona. Net self-employment income = gross income − business expenses. Self-employment tax = 92.35% of net income × 15.3% (12.4% Social Security up to $184,500 + 2.9% Medicare). Half of SE tax is deductible. Federal income tax uses 2026 brackets. Arizona's flat 2.5% state income tax applies to the same federal-style taxable income base (gross income minus business expenses, half of SE tax, and retirement contributions). Quarterly estimated taxes = total tax ÷ 4. This calculator excludes state-specific self-employment deductions/credits (e.g. state QBI-style carve-outs), local/county income or gross-receipts taxes, and state self-employment/franchise taxes some states levy separately from income tax — treat the state tax figure as an ordinary-income estimate, not an exact filing outcome.

Example Calculation

Let's calculate the full tax burden for a freelance designer in Arizona.

Gross freelance income: $110,000. Business expenses: home office ($1,800), equipment ($3,000), software ($2,400), health insurance ($7,200), vehicle ($3,500), professional development ($1,000). Total deductions: $18,900. Net SE income: $91,100. SE tax: $91,100 × 0.9235 × 15.3% = $12,866. Half SE deduction: $6,433. AGI: $84,667. Federal income tax: ~$13,700 (single, standard deduction).

Result: Total federal tax: ~$26,566 (SE tax $12,866 + income tax $13,700). Arizona income tax adds $3,000-$9,000 depending on rates. Effective total tax rate: 27-32% of gross income. Contributing $20,500 to a Solo 401(k) would reduce federal income tax by ~$4,500-$5,500 and build retirement savings.

This calculator does not model any ADDITIONAL state-specific business deductions or credits Arizona may separately allow — check with a local tax advisor or Arizona's tax agency.

Does this calculator include Arizona-specific deductions, credits, or local taxes?

No. The Arizona state tax figure here applies Arizona's real income tax rate structure (a flat 2.5%) to an estimated taxable income base. It excludes state standard deductions/exemptions, state tax credits, county or city income/gross-receipts taxes, and any state-level self-employment or franchise tax some states charge on top of income tax. Treat the result as a reasonable estimate, not a substitute for a tax professional.
