South Dakota senior property tax guide
Last updated: 22 September 2026
South Dakota has several property tax relief paths for older homeowners, but they work in different ways. The main statewide senior program is the Assessment Freeze for the Elderly and Disabled. People age 70 or older may also have a homestead deferral option. Rapid City and Sioux Falls have separate local help, and disabled veterans may qualify for stronger exemptions.
Bottom Line
As of 13 September 2026, the April 1 deadlines for the assessment freeze, homestead deferral, and Rapid City municipal reduction have passed. The July 1 state tax-refund deadline has also passed. A major deadline that is still ahead is November 1, 2026 for qualifying disabled-veteran and paraplegic-veteran property tax exemptions. If you are behind on taxes, call your county treasurer now instead of waiting for the next filing season.
If a Tax Deadline Could Cost You the Home
If property taxes are delinquent or you have a tax-deed notice, call your county treasurer and ask what is due, what step the case is in, and the last date to act. Use the official county treasurer directory to find the correct office.
- If the assessed value looks wrong: Contact your county Director of Equalization using the county director directory.
- If you need food, utility, or housing help: Call 211 or 1-605-339-4357. The 211 resource search can also help.
- If title, probate, a lien, or tax-deed papers are involved: Use South Dakota Legal Aid and tell them about any written deadline.

| Your situation | Best first route | 2026 status | Important limit |
|---|---|---|---|
| Age 65+ or disabled, rising assessment | Assessment freeze | April 1 deadline passed | 2026 income and home-value limits apply |
| Age 70+ and cannot pay | Homestead deferral | April 1 annual filing passed for Program 2 | Taxes and interest build up |
| Rapid City homeowner | Municipal reduction | April 1 deadline passed | Only the city tax is reduced |
| Sioux Falls homeowner | City refund after freeze approval | No separate city application | Up to $500; annual city funding |
| Disabled veteran or surviving spouse | Veteran exemption | November 1 deadline ahead | Service-connected disability rules apply |
What Has Changed
The March 2026 DOR notice sets the assessment-freeze limits at $56,595 for one person, $66,885 for a multi-member household, and $514,500 in full-and-true property value for a first-time applicant. These higher thresholds affect the 2026 application and 2027 taxes. Check the 2026 freeze notice.
The 2026 Tax Refund Program is a sales tax refund, not a direct property-tax reduction, and its July 1 filing deadline has passed. Read the 2026 refund notice.
Broader owner-occupied tax changes also began in 2026, with several effects reaching 2027 tax bills. See the 2026 tax package.
Assessment Freeze for the Elderly and Disabled
This is the main statewide property-tax program many older homeowners should check. It does not freeze the entire bill. It can stop the value used for tax purposes from increasing for a qualifying homeowner, while tax levies can still change.
Who may qualify
- You are age 65 or older, or disabled as defined by the Social Security Act.
- You owned an owner-occupied single-family dwelling and were a South Dakota resident for five years, unless you received the freeze in the prior year.
- You lived in the home for at least 200 days during the previous calendar year.
- Your household income was less than $56,595 if you lived alone, or less than $66,885 for a multi-member household.
- For a first-time 2026 applicant, the home’s full and true value was $514,500 or less. The state says a home over that limit may still fit if the applicant had previously qualified.
- An unremarried surviving spouse may continue to qualify in some circumstances.
How to apply
Applications are due every year to the county treasurer by April 1. The 2026 deadline has passed. The official PT 38 freeze form can be filled out for printing, but the form itself says it cannot be signed and submitted electronically.
Reality check
The state’s 2026 property-tax package says the higher assessment-freeze thresholds first apply to the 2026 application and will affect 2027 taxes. If you missed April 1, call the treasurer anyway and ask what to gather for the next filing cycle. Do not use a much older brochure as your source for the current income or home-value limit.
Homestead Deferral for People Age 70 and Older
South Dakota calls these homestead exemption programs, but the important word for readers is deferral. They delay property taxes. They do not erase the tax. The state’s December 2025 homestead deferral brochure explains two different paths.
Program 1: age and home value
If you were age 70 or older when you failed to pay property taxes and the home is assessed at $170,000 or less, the brochure says the county treasurer cannot take the property for back taxes under this program. The unpaid taxes still build up and accrue interest at 10% per year. They must be paid when the property is transferred.
Program 2: annual application
This program can defer taxes at 4% interest per year. You must be age 70 or older, or a surviving spouse of someone who was previously eligible. You must have owned the home for at least three years or have been a South Dakota resident for at least five years. Income from the previous calendar year must be less than $18,470 for a one-person household or less than $23,087 for a multi-member household. The annual application is due by April 1.
The brochure also says entering the homestead program makes the applicant ineligible for a property tax refund under the Sales or Property Tax Refund program, while the person may still qualify for a sales tax refund if the other rules are met.
Reality check: A deferral can protect cash flow, but it creates a lien and interest. Before using it, ask the county treasurer how much interest would build and what event would make the balance due.
Refunds, Rapid City Help, and Sioux Falls Help
2026 state Tax Refund Program
The state’s 2026 announcement describes the current program as a refund of part of the sales taxes paid in 2025. To qualify, a person had to live in South Dakota for all of 2025, be age 65 or older on or before January 1, 2025, or disabled at any time in 2025, and have income of $17,215 or less when living alone or $23,265 or less for a household.
The filing window was May 1 through July 1, 2026, so it is now closed. The DOR relief page says refund checks begin going out in early September. If you filed on time and have not heard anything, call the Department of Revenue at 1-800-829-9188 and choose the option for the refund program. For broader financial-help routes, our South Dakota benefits guide can help.
Rapid City municipal reduction
Rapid City is currently the only city using South Dakota’s municipal tax-reduction program for elderly and disabled homeowners. The program reduces the city part of property taxes the year after approval. The current municipal relief brochure lists maximum 2026 income below $20,778 for a one-person household and below $25,395 for a multi-member household. The applicant must also meet age or disability rules, own and reside in the property, and be within city limits. Applications are due each year by April 1 to the county treasurer.
Sioux Falls municipal refund
Sioux Falls has a different system. The city says it automatically refunds 100% of the municipal property tax up to $500 to homeowners approved for the state assessment freeze, if the city program continues to be funded. There is no separate city application. For a refund in 2026, the homeowner had to apply for the state assessment freeze by April 1, 2025. For a 2027 refund, the homeowner had to apply by April 1, 2026.
The city also requires the homeowner to be current, not delinquent, on property taxes for refunds issued on or after 2026. Check the Sioux Falls refund rules if you live in Minnehaha or Lincoln County.
Veteran and Paraplegic Property Tax Relief
Veteran-specific relief can be stronger than senior relief, so do not skip it when it fits.
Disabled veteran exemption
South Dakota exempts up to $200,000 of the full and true value of qualifying owner-occupied property. The veteran must be permanently and totally disabled because of a service-connected disability. An unremarried surviving spouse may qualify in some cases. The 2026 veteran deadline is November 1, 2026.
Paraplegic veteran exemption
The state also has a full property-tax exemption for qualifying paraplegic veterans, veterans with loss or loss of use of both lower extremities, and some unremarried surviving spouses. The home must be specifically designed for wheelchair use. The general DOR property tax relief page lists the program and the November 1 filing deadline.
Separate paraplegic reduction
South Dakota also has a graduated property-tax reduction for a paraplegic person, a person with loss or loss of use of both lower extremities, or certain surviving spouses. Income and occupancy rules apply, and the home must be designed for wheelchair use. DOR pages give conflicting filing instructions for this separate program, so confirm the next deadline and filing office with your county before relying on a date.
If you need help getting VA proof or finding the right county contact, use the official VSO locator or our South Dakota veteran guide.
Broader 2026 Property Tax Changes
South Dakota also adopted broader rules for owner-occupied homes. They are separate from senior-only relief.
- SB 216 valuation restriction: The restriction first appeared on 2026 assessment notices. If countywide owner-occupied valuation growth would exceed 3%, a reduction factor applies. Those values are used for 2027 tax bills.
- SB 216 budget limit: Taxing districts also face a five-year growth limit beginning with taxes collected in 2027.
- SB 245 and HB 1051: The state says owner-occupied property will have a reduced school general levy on 2027 tax bills.
- SB 96 county option: A county may choose a sales tax up to 0.5% to fund an owner-occupied property-tax credit, beginning no earlier than January 2027. It is optional.
These changes do not replace the senior freeze. For a national comparison, see our state tax relief guide. For other South Dakota tax issues that may affect older adults, see our South Dakota senior tax guide.
How to Start Without Wasting Time
- Find the parcel number. It should appear on the tax statement or assessment notice.
- Check owner-occupied status. South Dakota says a new owner should file owner-occupied status with the Director of Equalization by March 15. If it is missing or wrong, ask how to correct it for the next tax year.
- Use the right office. The treasurer handles many relief applications and tax-payment questions. The Director of Equalization handles assessed value, classification, owner-occupied status, and many exemptions.
- Ask which tax year changes. Some 2026 applications affect 2027 taxes rather than the bill already due.
- Keep proof of filing. Save a stamped copy, mailing receipt, or other proof showing when the form was submitted.
The DOR property tax page explains owner-occupied status and county contacts. For several kinds of public help, our South Dakota portal guide can help.
| Date | Program or action | Status | What to do now |
|---|---|---|---|
| March 12 | Usual local-board assessment appeal | Passed | Ask the county about any case-specific appeal right. |
| March 15 | Owner-occupied filing | Passed | Check the property record for next year. |
| April 1 | Freeze, homestead, Rapid City relief | Passed | Prepare early for the next annual cycle. |
| July 1 | 2026 state tax refund | Passed | If filed on time, ask DOR about status. |
| November 1 | Veteran exemptions | Still ahead | Gather VA and ownership proof now. |
The 2026 appeal guide lists the full assessment-appeal calendar. Case-specific deadlines after a decision can be different, so read any notice you received rather than relying only on the dates above.
Documents and Information to Gather
- Latest assessment notice and property tax statement
- Parcel number or legal description
- Photo ID and proof of age
- Proof the home is your main residence
- Federal tax return, if filed
- Social Security, pension, wage, interest, and other income records
- Income records for other household members when required
- Disability award letter if using disability eligibility
- VA rating letter for veteran relief
- Death certificate or spouse records for a surviving-spouse claim
- Deed, life-estate, trust, or probate papers if ownership is complicated
If property taxes are only one part of an unaffordable home, our South Dakota housing guide covers other housing-cost routes. If paying for care at home is also straining the budget, see our South Dakota home care guide.
Reality Checks That Save Trouble
- A freeze is not a frozen bill. It can limit the value used for tax purposes, but levies can still change.
- A deferral is debt. Taxes, interest, and a lien can follow the property until transfer.
- Old official PDFs can be stale. South Dakota’s current 2026 freeze notice carries much higher limits than an older freeze brochure still circulating online.
- City help is different. Rapid City uses a municipal reduction. Sioux Falls uses a refund tied to prior state-freeze approval.
- The 2026 refund deadline passed. Do not send an old application and assume it will be accepted.
- Veteran relief has its own deadline. November 1 is separate from the April 1 senior-program deadline.
Common Mistakes to Avoid
- Assuming age 65 automatically removes property tax.
- Using an old income limit copied from an older brochure.
- Calling the mortgage company instead of the county office that handles relief.
- Confusing the assessment freeze with a freeze on the full tax bill.
- Calling the 2026 state tax refund a direct property-tax cut.
- Missing the separate November 1 veteran deadline.
- Ignoring a title, trust, life-estate, or probate problem until a filing deadline is close.
If You Are Denied, Delayed, or Overwhelmed
Ask for the reason in writing. A missing-document problem may be fixable. An income, age, property-value, or residency problem may require waiting for the next year or using a different program.
If the problem is the assessed value, gather facts such as comparable sales, photos, incorrect square footage, wrong property classification, or proof of owner occupancy. The Director of Equalization should explain the value and the appeal path.
If the problem involves title, probate, or a tax-deed action, use legal aid early. If you need help organizing calls or finding aging and disability services, Dakota at Home can connect callers to local supports. Our South Dakota disability guide may also help when disability affects more than property tax.
If property-tax relief does not fit
Ask about a payment plan or other county option before taxes become more delinquent. If housing, utilities, food, or another urgent bill is larger, use those assistance systems too. Missing one tax deadline does not mean every other form of help is closed.

Resumen en Español
En Dakota del Sur, el programa principal para muchos propietarios mayores es el Assessment Freeze. Para la solicitud de 2026, el límite de ingresos es menos de $56,595 para una persona o menos de $66,885 para un hogar con varias personas. El límite del valor total de la vivienda es $514,500 para muchos solicitantes nuevos. La fecha límite fue el 1 de abril de 2026, por lo que ahora conviene llamar al tesorero del condado y prepararse para el próximo ciclo.
El programa Homestead para personas de 70 años o más puede aplazar los impuestos, pero no borra la deuda. Puede generar intereses y un gravamen sobre la propiedad. El reembolso estatal de 2026 cerró el 1 de julio. La fecha del 1 de noviembre de 2026 todavía puede ser importante para algunas exenciones de veteranos discapacitados. Si no puede pagar los impuestos o recibió una notificación de deuda, llame al tesorero del condado de inmediato.
Frequently Asked Questions
Does South Dakota have one senior property tax exemption?
No. South Dakota uses several programs. The main senior path is the assessment freeze. People age 70 or older may have homestead deferral options, while Rapid City, Sioux Falls, and veteran programs have separate rules.
What are the 2026 assessment-freeze limits?
For the 2026 application, income must be less than $56,595 for a one-person household or less than $66,885 for a multi-member household. The full-and-true-value limit is $514,500 for a first-time applicant, with an exception for some people who previously qualified.
Can I still apply for the 2026 assessment freeze?
The normal 2026 deadline was April 1, so it has passed. Call the county treasurer anyway if you have a special situation, and ask what to prepare for the next annual filing.
Does the homestead program erase my taxes?
No. The homestead programs described by South Dakota are deferrals. Unpaid taxes accrue interest and remain tied to the property until the required payment event, such as transfer of the property.
Is the 2026 state tax refund still open?
No. The 2026 filing deadline was July 1. The current DOR announcement describes the 2026 program as a refund of part of the sales taxes paid in 2025. The DOR says checks begin going out in early September.
What property tax deadline is still ahead in 2026?
November 1, 2026 is the main statewide deadline still ahead for the disabled-veteran and paraplegic-veteran property tax exemptions. Other case-specific deadlines can apply, so read any county notice you received.
