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 SALT deduction 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.

SALT cap rules are federal and may change with legislation. Not legal or tax advice.
