South Dakota Sales Tax Refund for Seniors and Disabled Adults (2026)

What Changed in 2026

In March 2026, South Dakota enacted Senate Bill 21. It repealed the separate property-tax refund chapter and revised the sales and service tax refund for older adults and people with disabilities. See the 2026 SB 21 record and the newer state refund rules. The old phrase “sales or property tax refund” remains on some online materials. That old label is not proof you can still claim a separate property-tax refund.

For the 2026 application season, DOR said eligible people could seek a refund of part of the sales taxes paid in 2025. The state described one 2026 refund payment, rather than two separate payments. Its 2026 refund FAQ says eligible checks were scheduled for early September. A scheduled mailing date does not mean every household has received a check.

This change does not end the assessment freeze, homestead deferral, or qualifying local tax breaks. Those are different programs with different forms. Our state tax relief comparison helps explain why the names differ across states.

Who Could Qualify for the 2026 Refund?

The 2026 refund was based on where you lived, your age or disability status during the correct year, and the income of your household. DOR’s 2026 application announcement said applicants needed to have lived in South Dakota for all of 2025. They also needed to have turned 65 by January 1, 2025, or have been disabled at some point in 2025.

Younger adults can qualify through disability. The state’s disability proof guidance refers to Social Security Disability or Supplemental Security Income disability eligibility during part of 2025, and a Veterans Affairs disability rating of at least 60%. A doctor’s note alone may not prove the state definition. Ask DOR which letter shows your status.

The refund uses the income of the household, not just the person signing the form. The state law’s income and household definitions includes many kinds of income, including Social Security and pension payments, even when they are not taxed on a federal return. It also has specific rules for people sharing a dwelling and for certain renters or boarders. Do not decide someone is excluded just because they share your address. Explain your living arrangement to DOR.

These were the rules for the 2026 refund season, not confirmed 2027 limits. The enacted one-person refund statute and multiple-person refund statute say “or less” at the stated income limits. A DOR FAQ says “less than,” which does not match the law at the exact dollar boundary. If your income equals a limit, ask DOR to apply the statute rather than ruling yourself out.

The program is not limited to people who own a house. It is a sales tax refund; a renter can ask about it. Owning and living in a home becomes important for the separate assessment freeze and some other property-tax programs.

How Much Money Could You Get?

The dollar figures in the table are ceilings, not standard checks. State law directs DOR to divide the money set aside among qualifying people who filed on time. The refund allocation law explains this shared-funding rule. The number of valid claims affects the final amount.

How to Apply Without Using the Wrong Form

1. Check the correct filing year. The 2026 application was for 2025. A 2027 form should name the year it covers. Wait for that year’s official instructions before entering figures.
2. Open the official route. DOR linked a refund application portal from its 2026 notice. The accessible form page may still display an older-year notice or old property-tax fields. Treat such text as a warning: confirm the live year’s version with DOR before sending personal information.
3. Ask for paper help if needed. Under the filing and assistance statute, county treasurers can provide forms and help forward them to DOR. DOR can also mail an application. Find your office through the county treasurer directory.
4. Send the whole household’s proof. Ask DOR which income records and disability papers fit your case. Keep copies of the completed form and any receipt, mailing record, or confirmation number.
5. Confirm that it arrived. Mail for this refund goes to the Department of Revenue’s Tax Refund Office, 445 E. Capitol Avenue, Pierre, SD 57501-3185, according to its 2026 notice. Before mailing late or filing for a new year, confirm that address and what the office will accept.

Do not confuse the deadlines. The May 1–July 1 window was the 2026 sales-tax refund period. The April 1 deadline belongs to the assessment freeze and some other property programs. Submitting one program’s form does not file the other program for you.

Sales Tax Refund Versus Property Tax Freeze

The refund returns some money to an eligible household after it files a claim. The assessment freeze works on the value used to tax a qualifying home. It does not send a sales-tax refund check or lock the entire property-tax bill.

The freeze generally requires owning and occupying a qualifying home, meeting a prior-residency test, living in the home for enough days, and staying within income and property-value rules. The annual freeze form goes to the county treasurer by April 1. The assessment freeze filing law sets that deadline. Ask the office to explain what tax year an approved freeze would affect.

Can you receive both? Yes, qualifying for the freeze does not by itself bar a sales-tax refund. South Dakota’s assessment freeze coordination law says so. But the two programs still screen you separately, and you must apply through the correct route. The municipal relief coordination statute also says certain municipal property-tax reductions cannot be denied merely because someone receives the freeze or sales-tax refund. That does not mean your city offers the reduction.

Other tax programs may have rules about loans, liens, or overlapping benefits. In particular, do not assume homestead deferral can be combined freely with every refund or reduction based on older brochures. Ask the county and DOR how an existing deferral affects your case.

If You Missed the Deadline or Were Denied

Missed July 1, 2026

As of October 13, the regular 2026 application window is closed. However, the state late-filing rule allows the Secretary of Revenue to extend the filing period by up to six months for sickness, absence, disability, or other good cause. This is a possible exception, not a general second filing season. Call DOR promptly, explain the reason, ask how to make a written request, and ask for a decision in writing. Do not assume that simply uploading an old form preserves a claim.

Denied or paid less than expected

Ask for the written reason first. Common questions include which people counted as household members, what income was included, whether the correct year was used, and whether proof of disability was accepted. The state refund appeal law allows a person denied all or part of a claim to demand a hearing within 30 days after receiving notice. If you are near that point, ask DOR immediately how to send the hearing request.

If the issue is instead a home assessment or overdue tax bill, the refund appeal is not the right process. Call the county treasurer or the Director of Equalization office for the proper tax or valuation route. Do not wait for a refund if your property taxes are delinquent.

Documents and Questions to Prepare

• Proof of South Dakota residence for the year on the application.
• Birth date and ID, or the disability award or VA rating record that DOR asks for.
• Social Security statements, pension and annuity records, tax returns, pay, and other household income papers.
• Names of people sharing the home and a clear note if someone is a tenant or boarder.
• Any letter or form from an earlier refund year, plus a current mailing address.
• If you also seek a freeze, property tax papers and proof of home ownership and occupancy.
