South Dakota Property Tax Relief: Owner-Occupied Status by March 15, the 2026 Relief Laws, and Help for Seniors and Veterans

South Dakota doesn’t have a classic homestead exemption that knocks a flat amount off every home. The first step for any homeowner is the owner-occupied classification , claimed by March 15 [1][2]. On top of it, the Legislature passed new relief in 2025 and 2026 [3], and there are programs for seniors, disabled owners and veterans [4].

Step one: the owner-occupied classification

Every owner-occupied single-family dwelling is taxed as its own class [1]. That includes a house, condo, townhome, a building of four or fewer units, a qualifying housing co-op and a manufactured or mobile home, along with its garage and the land under it [1]. You can have only one owner-occupied dwelling, and it has to be your principal place of residence [1]. If you live in half or more of the living space, the whole dwelling qualifies; in a duplex, triplex or fourplex, the part you live in qualifies [1].

To get it, you sign a certificate, under penalty of perjury, and file it with your county director of equalization by March 15 [2]. Once granted, the classification stays until the property is sold or its use changes [2]. Owners of a manufactured or mobile home file the certificate when they register it [2].

Recent relief laws

The South Dakota Department of Revenue summarizes three recent laws [3]:

Assessment freeze for seniors and disabled owners

The Freeze on Assessments keeps your home’s value from going up for tax purposes; if the market value rises, you’re taxed on the earlier, lower value [5]. It covers the house, garage and lot, or one acre, whichever is less [5].

To qualify, you must [5]:

• Be 65 or older, or disabled as defined by the Social Security Act.
• Have owned an owner-occupied single-family home and lived in South Dakota for five years, unless you had the freeze the year before.
• Have lived in the home at least 200 days of the previous calendar year.
• Meet the income limit, based on the previous year: under $56,595 for a one-person household or under $66,885 for a household of more than one. “Income” means federal adjusted gross income plus other income, including Social Security.

A home with a full and true value of $514,500 or more isn’t eligible unless it already had the freeze in a prior year [5]. An unremarried surviving spouse of someone who qualified may still qualify [5]. Apply every year to your county treasurer by April 1 [5].

Disabled and paraplegic veterans

• Disabled veteran exemption: $200,000 of the full and true value of an owner-occupied dwelling is exempt for a veteran rated permanently and totally disabled from a service-connected disability [6]. An unremarried surviving spouse receiving dependency and indemnity compensation can also qualify [7]. Apply to your county director of equalization by November 1, with a VA statement of your rating [7]. Once approved, you don’t reapply; it stays until the home is sold, you stop living there, or its use changes [6][7]. A veteran who missed the deadline because a permanent and total rating was still pending with the VA can get taxes abated or refunded back to the claim’s effective date, for up to four years [6].
• Paraplegic veterans: a dwelling designed for wheelchair use and owned and occupied by a paraplegic veteran, a veteran with loss or loss of use of both lower extremities, or that veteran’s unremarried widow or widower, is fully exempt [9]. Apply to the director of equalization by November 1 [4].

Tax refund for seniors and people with disabilities

The Tax Refund for Senior and Disabled Citizens sends a check, not a bill credit [8]. You need to have lived in South Dakota the entire previous year and been 65 by January 1 of that year, or disabled during it (for a VA disability, rated 60% or more) [8]. Income has to be less than $17,215 for one person or less than $23,265 for a household [8].

The maximum refund is $500 for one person and $1,000 for a household, and the actual amount depends on income and how many people apply [8]. Applications run May 1 to July 1, and checks go out in early September [8]. There’s no applying late for a past year [8].

Tax deferral at 70 (the “homestead exemption”)

South Dakota’s Homestead Exemption programs don’t reduce your tax; they let you delay it until the home is sold, with the unpaid taxes staying as a lien [10].

To qualify, you must be 70 or older, or the surviving spouse of someone who was eligible, and have owned the home at least three years or lived in South Dakota at least five years [10]. There are two versions [10]:

• Program 1, based on age and home value: deferred taxes accrue interest at 10% a year. The county treasurer also can’t take your home for back taxes if you were 70 or older when you failed to pay and the home is assessed at or below $170,000 [10].
• Program 2, based on age and income: household income under $18,470 for one person or $23,087 for more than one, and deferred taxes accrue interest at 4% a year. It requires a new application each year [10].

Applications go to your county treasurer by April 1 [10]. Joining a deferral program makes you ineligible for a property tax refund under the refund program above, though you may still get a sales tax refund [10].

Rapid City residents

A municipal property tax reduction for elderly and disabled owners is offered only in cities that adopt it by ordinance, and Rapid City is currently the only one [4]. It reduces city property taxes the year after you apply; contact the Pennington County Treasurer by April 1 [3][4].

Where to start

• County director of equalization: owner-occupied certificate (March 15), disabled and paraplegic veteran exemptions (November 1) [2][7][4].
• County treasurer: assessment freeze and deferral programs (April 1) [5][10].
• South Dakota Department of Revenue: the senior and disabled tax refund (July 1) [8].
