South Dakota SALT deduction optimizer
See how the federal SALT cap affects South Dakota property and sales taxes.
How this optimizer works
Step 1 sums your state income tax (typically $0 in South Dakota), property tax, and sales tax to estimate total SALT.
Step 2 applies the federal $10,000 SALT cap to show how much is deductible if you itemize. Optional marginal rate input converts this into a tax savings estimate.
Frequently asked questions
Does South Dakota change the SALT cap?
The SALT cap is a federal rule and applies to South Dakota taxpayers who itemize. South Dakota has no state income tax, so SALT is mostly property and sales taxes.
What if I take the standard deduction?
The SALT cap only matters when itemizing. Compare itemized deductions to the standard deduction before applying the cap.
