South Dakota Property Tax Relief for Surviving Spouses: Three Programs and Their Deadlines

Property taxes are the bill that keeps coming regardless of grief, income changes, or life disruption. For a surviving spouse on a fixed income — especially one now managing the household alone — a rising property tax bill can threaten the family home. South Dakota offers three distinct programs that can either freeze your tax basis, delay payment entirely, or exempt significant portions of your home's value.

None of these programs apply automatically. They require annual applications filed with your county treasurer or assessor, and the filing deadlines are rigid. If you miss April 1st for most programs, you wait another full year.

Program 1: Assessment Freeze for the Elderly and Disabled

This is the most widely used program for surviving spouses on fixed incomes. It locks in the assessed value of your home at its current level, preventing the assessed value from increasing for property tax purposes even as market values rise. You continue to pay taxes on the same fixed assessed value year after year.

Who qualifies:

• Age 65 or older, OR disabled as defined by the Social Security Act
• Own and occupy the home as your primary residence
• Household income under $56,595 (single-member household) or $66,885 (multiple-member household) — these limits adjust annually for inflation
• Property valued at or below $514,500

Key provision for surviving spouses: If your deceased spouse previously qualified for the Assessment Freeze, you as the unremarried surviving spouse can seamlessly continue the benefit — even if you are not yet 65 yourself — provided you meet the income limits.

Application: File Form PT38 with your county treasurer by April 1st annually. The freeze does not carry forward automatically year to year — you must reapply.

Program 2: Property Tax Homestead Exemption

The Homestead Exemption works differently from the freeze. Rather than capping the assessed value, it delays property tax payments entirely until the property is sold or transferred. The accrued taxes accumulate as a lien on the property.

This is particularly useful for surviving spouses who own their home outright and have very low income — it eliminates the annual cash outflow for property taxes while they're alive, with repayment deferred until the home is eventually sold.

Who qualifies:

• Age 70 or older, OR an unremarried surviving spouse at any age
• Own and occupy the home as your primary residence

The "any age" provision for surviving spouses is significant. You do not need to be 70 to qualify — widows and widowers qualify based solely on their status.

Important trade-off: If you use the Homestead Exemption, you are ineligible for the Sales and Property Tax Refund Program (the senior citizen tax refund described below). Choose the program that provides greater annual benefit.

Application: File with your county treasurer by April 1st annually.

Program 3: Veteran-Related Property Tax Exemptions

South Dakota provides two property tax exemptions specifically for the surviving spouses of veterans.

Exemption for Unremarried Widow/Widower of a Totally Disabled Veteran:

• Exempts up to $200,000 of assessed value from property taxation
• Applies when the veteran was rated permanently and totally disabled from a service-connected injury
• The spouse must be unmarried

Full Exemption for Unremarried Spouse of a Paraplegic Veteran:

• Provides a complete exemption from all property taxes
• Applies when the veteran was a paraplegic, or when the home was specifically designed or substantially altered for wheelchair use
• The spouse must be unmarried

Application: File Form PT46a or PT46c with your county assessor by November 1st annually. Note this deadline is November 1 — not April 1 like the other programs. Missing the November 1 deadline means waiting until the following tax year.

South Dakota Senior Citizen Tax Refund

The Department of Revenue also administers a Sales and Property Tax Refund Program for residents 65 and older meeting income requirements. This refunds a portion of property taxes paid — but as noted above, participants in the Homestead Exemption are excluded.

If you qualify by age but your income makes the refund more valuable than the deferred-payment approach, the refund program may be the better choice. Contact your county treasurer to compare the dollar difference for your specific situation.

Practical Steps: How to Apply

1. Identify your county treasurer's office. All applications for the Assessment Freeze and Homestead Exemption go through the county treasurer where your property is located.

2. Gather documentation. Typically required: proof of age (driver's license or birth certificate), proof of income (most recent tax return or SSA benefit statement), proof of ownership (deed), and documentation of your spouse's death (certified death certificate) if claiming continuation of a previously approved exemption.

3. Apply before April 1st for the Assessment Freeze and Homestead Exemption. For veteran exemptions, apply before November 1st.

4. Reapply annually. These programs require annual renewal. A notice in your calendar for February or March (for April deadlines) and September or October (for the November veteran deadline) prevents accidental lapses.

What These Programs Don't Cover

These property tax programs reduce or defer the tax burden on your home, but they don't address other pressing financial needs following a death: health insurance continuity, pension and Social Security claims, life insurance collection, or estate-related deadlines.
