Sales tax deduction in South Dakota

Varies

Is Sales Tax Deductible in South Dakota?

Short answer: Yes, and it's usually your best option: South Dakota has no income tax, so itemizers deduct sales tax instead (4.2% state rate, about 6.11% with local taxes). Groceries are taxed at the full state rate; instead of sales tax, vehicles pay a 4% motor vehicle excise tax. The reduced 4.2% rate is scheduled to sunset in June 2027.

Use the IRS Sales Tax Deduction Calculator or your receipts, add sales tax paid on a car, boat, or home-building materials, and stay within the $40,400 SALT cap (Schedule A line 5a).

Records to keep: Keep your state return, W-2s and 1099s (1099-R, SSA-1099), and any state credit worksheets. Check your state revenue department's current-year instructions before you file.
