Can You Write Off Louisiana state income tax?
Short answer: Louisiana switched to a flat 3% income tax in 2025 with a bigger standard deduction, and people 65+ can exclude up to $12,000 of retirement income.
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.
