What Happens If Sauk County Property Taxes Are Late?
Late tax payments can affect the entire balance, not just one installment. Read this before mailing late, paying a second installment, buying a property or checking escrow.

| Interest and penalty | County explains delinquent taxes accrue interest plus penalty at 1.5% per month from February 1 when the first installment remains unpaid. | Do not estimate payoff yourself; verify with Treasurer. |
| Buying property with unpaid taxes | Tax bills, special charges and delinquent balances can affect closing calculations. | Check ALRS, tax history, title records and closing payoff figures. |
| Tax deed / foreclosure concern | County Treasurer pages may list tax deed or foreclosure-related properties. | Verify status directly with Treasurer before bidding or buying. |
