South Dakota Assessment Freeze for Elderly and Disabled Homeowners

What Changed for 2026

The Department of Revenue’s 16 March 2026 notice announced higher income and home-value limits and the 1 April deadline. The values in older brochures and search results may be much lower. South Dakota law now adjusts the basic limits by an index factor each year. For context, state relief rules vary. That does not mean the 2026 dollar limits will remain valid for 2027.

A separate 2026 proposal to raise the multi-person base income limit to $85,000, Senate Bill 196, was introduced but did not pass the Senate. Do not use that proposal as an eligibility rule.

How the Assessment Freeze Works

South Dakota taxes property using an assessed value. A freeze can hold the value used for a qualifying home at a base-year amount even if its market value rises. The freeze does not erase taxes already due, and tax rates can still change.

Under the state definition of a base year, the year is linked to when the owner reached age 65 or became disabled. The law also permits an applicant to select an assessed value from a later year. Ask the county which base-year value should apply. Do not rely on an online estimate.

Covered property means the home, its garage, and the lot beneath it or one acre, whichever is less. The legal definition also covers certain condominiums and manufactured homes taxed as separate units. Ask which parcel and structures count.

The freeze is statewide, unlike some city relief programs. The state lists it in its property tax relief system. For a broader picture, our South Dakota tax relief guide compares the main programs without replacing this filing guide.

Who May Qualify in 2026?

You must meet several rules together. Being 65 does not, by itself, approve a freeze. The state’s eligibility law covers ownership, state residence, time in the home, household income, and a base year.

• Age or disability: You are at least 65 or have a disability that meets the program’s Social Security Act standard. A person younger than 65 may qualify on the disability route.
• Ownership and residence: You have owned an owner-occupied single-family home and lived in South Dakota for at least five years, unless you received this freeze the prior year.
• Time at home: You lived in the home at least 200 days during the preceding calendar year.
• Income: Your total household income is under the applicable program-year limit.
• Home value: For 2026, the department published a $514,500 value limit. The law has an exception for people who previously received the freeze on the same dwelling.

The official property-value law uses the home’s full and true market value, not a number you choose from a sales website. Ask your county Director of Equalization what value is on record. Ask for a written explanation when close to the cutoff.

Special ownership and family situations

State law recognizes certain joint owners, life estates, recorded contracts for deed, and trust interests as ownership. Those cases may need extra papers. An unremarried surviving spouse of a person previously approved can also remain eligible if other conditions hold. Do not assume a spouse inherits the freeze without filing. Ask the treasurer to review the deed and the prior approval record.

If disability proof is the sticking point, our South Dakota disability guide points to related state assistance. It does not decide eligibility for this tax program.

How Household Income Is Counted

For the 2026 application, the official limits were less than $56,595 for a one-person household and less than $66,885 for a household with more than one person. These are household totals, not per-person allowances.

Under the income definitions, the calculation is broader than taxable wages. It can include Social Security payments, pensions, some retirement withdrawals, certain benefits, gifts, and other income that may not appear the way you expect on a tax return. The law generally looks at income received in the preceding calendar year by people while they were members of the household.

The law treats some contract tenants differently. If an adult child lives with you, ask the treasurer whose income counts.

These are 2026 amounts only. The 2027 indexed dollar figures had not been confirmed on the checked state guidance as of 13 October 2026.

How to Apply Through Your County

Use Form PT 38. Applications are available each January and must reach your local county treasurer by 1 April every year. A fillable web copy is not a completed electronic filing. Print, sign, and send the form as the county instructs.

1. Ask the treasurer which filing cycle applies and whether the current form is ready.
2. Get your parcel number and confirm the home is shown as owner-occupied.
3. Complete every eligibility and income question. Do not leave a household member off because their income is not taxable.
4. Attach the evidence the county requests. Under state law, the treasurer may require documents to check your claim.
5. Sign the certificate and send it to the county office. Keep a full copy and proof of delivery.
6. Ask when you should check that the treasurer certified the application to the Director of Equalization.

What to gather before filing

• Latest assessment notice or tax bill, property address, and parcel number.
• Proof of age or documents showing the qualifying disability.
• Proof of ownership, or trust, life-estate, or contract papers when relevant.
• Income records for all people who count in the household, such as tax returns, Social Security statements, pension notices, and other receipts.
• Information about time spent in the home during the previous year.
• Prior freeze approval if renewing or applying as a survivor.

The treasurer checks eligibility. If approved, the county Director of Equalization applies the frozen value under the state certification rule. Ask which assessment and tax-payment year will reflect the decision. Property taxes do not necessarily change on the next bill you open.

If You Missed the Deadline or Were Denied

The normal 2026 deadline was 1 April 2026. As of 13 October, that date has passed. But South Dakota law 10-6A-4 provides a possible petition route for a person who missed the previous year’s April deadline yet otherwise qualified. The petition goes to the board of county commissioners and asks for recalculation and abatement of the tax difference.

That is not an automatic extension. Ask the county which missed tax year may be reviewed and what proof is needed. Ask about tax-deed deadlines if taxes are overdue.

When the treasurer denies a freeze in full or in part, law 10-6A-9 allows a person to demand a hearing before the Secretary of Revenue within 30 days of receiving notice. Keep the notice and envelope, ask how to file the demand, and get legal help if you face a large bill or unclear ownership.

Freeze Versus a Refund or City Reduction

An assessment freeze reduces the value used to calculate tax. It does not send you a check. South Dakota also has a sales-tax refund program for eligible older and disabled residents, with separate income rules and a different application period. Rapid City has a separate municipal property tax reduction. That city program does not apply throughout the state.

There is an important 2026 legal change. Senate Bill 21 became law and repealed the former stand-alone property-tax-refund chapter, 10-18A. However, the Department of Revenue’s relief page still labels its 2026 refund application as being for 2025 taxes. Do not assume that old property-tax refunds remain a new annual option in 2027. Ask the Department of Revenue which refund type and year the current form covers.

State law 10-6A-11 says receiving the assessment freeze does not affect eligibility for the separate retail sales and service tax refund. Do not assume every form of tax relief combines. See our state-by-state tax guide for why program labels differ elsewhere.

Reality Checks and Common Mistakes

• Do not confuse assessed value with your bill. Levies and other taxes can change even after a value freeze.
• Do not reuse old income limits. The law has an annual index; ask for the 2027 thresholds when that cycle opens.
• Do not treat the PT 38 website as online submission. State instructions require a signed form delivered to the county.
• Do not ignore annual renewal. Prior eligibility is not an endless exemption.
• Do not conceal income or ownership facts. A false claim can lead to back taxes, a lien, and a multi-year bar under the false-application law.

If you cannot afford the tax bill now, contact the treasurer about delinquency and other payment routes. An assessment freeze is not an emergency payment program.
