Estimates only — single filers only. Federal tax is estimated using 2026 IRS brackets (per IRS Rev. Proc. 2025-32) with a $16,100 standard deduction. The seven 2026 brackets for single filers are: 10% ($0–$12,400), 12% ($12,401–$50,400), 22% ($50,401–$105,700), 24% ($105,701–$201,775), 32% ($201,776–$256,225), 35% ($256,226–$640,600), and 37% (over $640,600). Traditional 401k/403b, HSA, and FSA contributions are subtracted from gross income before applying all tax rates, reducing your estimated AGI. FICA (Social Security) and Medicare are calculated on full gross wages — in practice, Section 125 HSA/FSA contributions may also reduce FICA wages slightly, but this tool applies them to full gross as a conservative estimate. State and local taxes are applied to the same AGI as federal taxes. This tool does not account for tax credits, the alternative minimum tax, or state-specific deduction differences. Results are for single filers only and will differ for married or head-of-household filers. Always consult a licensed financial advisor or CPA for personalized guidance.
