Can You Write Off Massachusetts state income tax?
Short answer: Massachusetts has a 5% flat rate plus a 4% surtax on income over about $1 million, and renters can deduct half their rent up to $4,000.
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.
