Can You Write Off South Dakota state income tax?
Short answer: South Dakota has no personal income tax and is a common domicile for RV full-timers and trusts.
No state income tax means nothing to deduct for state income tax on your federal return, but sales and property taxes can still count toward the SALT deduction 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.
