Can You Write Off Colorado state income tax?
Short answer: Colorado has a flat income tax of 4.4% (sometimes temporarily lower) and lets retirees subtract a large share of pensions and Social Security.
State and local income, sales, and property taxes share one SALT cap ($40,400 for 2026, reduced above about $505,000 of income) and only help if you itemize.
Records to keep: Keep receipts, statements (1098, 1098-T, 1099, W-2G), and a note of what each cost was for. Compare itemizing to the 2026 standard deduction before you claim.
