Property Tax Breaks for Seniors in South Dakota (2026)

Updated August 12, 2026. Quick answer: South Dakota runs four separate programmes and you apply for each one by April 1, every year. The assessment freeze at 65 holds your home’s taxable value at its base-year level. The municipal reduction cuts city taxes on a graduated scale — but only in a city that adopted it, and the state names Rapid City as the only one. The refund pays up to $1,000 back. And two homestead exemption programmes stop the county collecting at all — that is a deferral: the tax accrues, becomes a lien, and is paid when the house changes hands.

What South Dakota offers

• The assessment freeze at 65 — and the base year you may not have expected — SDCL § 10-6A-2 entitles you to freeze the assessment on a single-family dwelling if your household income is under the limit, you have been an owner and a South Dakota resident for 5 years, you lived in the house at least 200 days of the previous calendar year, and you have established a base year. § 10-6A-1(1) sets the base year as the year you turned 65 — and § 10-6A-1(2) adds that “the applicant need not have been the owner of the dwelling during the base year”, and may elect a later year instead. The freeze is on value, not on the bill: the levy can still rise.
• The freeze’s real limits are $56,595 / $66,885 of income and $514,500 of value — not what the statute says — § 10-6A-2(1) reads $55,000 for a single-member household and $65,000 for a multiple-member one, and § 10-6A-3 excludes a dwelling worth $500,000 or more. Both sections were amended in 2025 to index those figures annually from January 1, 2026, by the greater of CPI-W or the Social Security increase. The Department of Revenue’s current brochure prints the result: income under $56,595 single or $66,885 multi-member, and a value limit of $514,500. If you were turned away on the statutory numbers in an earlier year, the current ones are higher.
• The municipal reduction — up to 100% of your city tax, in one city — SDCL ch. 10-6B lets a municipality adopt, by resolution, a graduated reduction of its own property taxes for owners 65 or older or disabled who have owned and lived in the home for five years. § 10-6B-2 is explicit that “only taxes levied by the municipal government that has enacted a resolution” are reduced — and the Department of Revenue states that Rapid City is currently the only municipality that allows it. The current schedule, from the department’s brochure (the statutory bands at §§ 10-6B-6 and 10-6B-7 have been indexed annually since 2024 under § 10-6B-7.1):

  Reduction	Single-member income	Multi-member income
  100%	$0 – $16,159	$0 – $21,354
  75%	$16,160 – $17,314	$21,355 – $22,508
  50%	$17,315 – $19,622	$22,509 – $24,239
  25%	$19,623 – $20,777	$24,240 – $25,394
  0%	$20,778 and over	$25,395 and over

  § 10-6B-8 carries the multi-member schedule over to a widow or widower who has not remarried and stays in the same dwelling, and § 10-6B-15 confirms this reduction is not denied because you also take the refund or the freeze.
• The refund — up to $500 or $1,000, claimed by July 1 — SDCL § 10-45A-2 repays sales and service tax to a person 65 or older before January 1 of the claim year, or disabled at any time in it, who was a resident all year. § 10-45A-5 caps a single-member household at $500 on income of $17,215 or less; § 10-45A-6 caps a multi-member household at $1,000 on $23,265 or less — both figures as amended in the 2026 session and confirmed on the department’s current page. The claim window is May 1 to July 1 (§ 10-45A-8), and the secretary may extend it up to six months for sickness, absence or other good cause.
• Two programmes that defer the tax — at 4% or 10% interest — The state calls both “homestead exemption”; both are deferrals. Programme 1 rests on SDCL § 43-31-1: the homestead of an owner 70 or older (or the unremarried surviving spouse) worth less than $170,000 “is exempt from sale for taxes”, so the treasurer cannot take the house for unpaid tax; the department states the accrued tax carries 10% a year and is payable on transfer. Programme 2 is SDCL ch. 10-6C, enacted in 2023: on an annual application, an owner from age 70 with three years’ ownership or five years’ residency, eight months’ occupancy and income under $18,470 single / $23,087 multi-member (the statute’s own $16,000 and $20,000, indexed since 2024) has collection prohibited. § 10-6C-8 makes the unpaid tax a lien filed with the register of deeds, carrying interest at the Category E rate — 4% a year per the department — and bars transfer until it is paid in full.
• What the deferral programmes protect you from, and what they cost — § 10-6C-9 keeps the deferred tax from being treated as delinquent and bars the county from publishing your name — the public-shaming list that usually follows unpaid property tax. § 10-6C-10 caps the total that can accrue at the value of the property itself, so the debt cannot exceed the house. § 10-6C-11 lets anyone — a child, a trust — pay some or all of it at any time, oldest tax first. But the department is equally plain that entering programme 2 makes you ineligible for the property-tax half of the refund programme, though the sales-tax refund may still be claimable. Talk to whoever will inherit the house before you apply.

The catch most senior-exemption roundups skip

Every one of these is an annual application, due April 1 — the freeze (§ 10-6A-4), the municipal reduction (§ 10-6B-9) and both homestead-exemption deferrals. There is no “approved once, approved forever” here as there is in most states, and the sales-tax refund runs on a different clock again, May 1 to July 1.

Missing April 1 on the freeze is not necessarily fatal. § 10-6A-4 lets someone who missed the deadline for the previous year, but otherwise qualified, “petition the board of county commissioners to recalculate the taxes based on the valuation the person would have received under this program and abate the difference”. Almost nobody is told this.

A false application is a perpetual lien. § 10-6A-12 assesses back the whole reduction obtained by misrepresenting ownership or income, makes it a perpetual lien on the property under § 10-21-33, and bars you from the freeze anywhere in the state for three years.

How to apply

Applications for the freeze, the municipal reduction and both homestead exemption programmes go to your county treasurer, annually, on or before April 1; forms are available from January at the courthouse or the Department of Revenue’s property tax page, and §§ 10-6A-4 and 10-6B-9 require the treasurer to help you complete them if you ask. The sales and property tax refund goes instead to the department’s Special Tax Division in Pierre between May 1 and July 1; if you qualified last year the application is mailed to you in early May. A denial of any of them gets a hearing before the secretary of revenue within thirty days (§§ 10-6A-9, 10-6C-6).

Two things to check before you count on it

• Thresholds move. Age and income limits are reset by legislatures and are frequently indexed. Every figure above carries the year we confirmed it; confirm the current one before you budget around it.
• Your county or town may add its own. Statewide programmes are the floor. Counties and municipalities frequently run additional exemptions, and those are where a lot of real money sits.

Disabled Veteran Property Tax Relief in South Dakota: $200,000 Exempt, and a Full Exemption for Paraplegic Veterans

The South Dakota Department of Revenue's published property tax relief programs guidance is the primary authority for this state-specific rule.

• South Dakota's disabled veteran program exempts up to $200,000 of the assessed value for qualifying property, which is the same property eligible for the owner-occupied classification.
• The property must be owned and occupied by a disabled veteran or an un-remarried surviving spouse, and the veteran must be rated as permanently and totally disabled as a result of a service-connected disability.
• A separate paraplegic veteran program exempts the property from all property taxes where the property is owned by a paraplegic veteran, a veteran with loss or loss of use of both lower extremities, or the unremarried widow or widower of such a veteran, and is specifically designed for wheelchair use within the structure.

Before applying, match the rating letter, ownership, occupancy, survivor status, and filing timing in your records to the controlling text; confirm current filing instructions with the administering agency.
