Methodology
Take-home figures assume a single filer taking the standard deduction with wage income only, no credits, itemized deductions, or local taxes. Federal tax uses the 2026 IRS brackets (Rev. Proc. 2025-32); FICA is 6.2% Social Security to the $184,500 wage base plus 1.45% Medicare. State tax walks Colorado's 2026 brackets. See the full methodology.
