South Dakota's Assessment Freeze (SDCL 10-6A) for Seniors at $35,000 Single / $45,000 Multi-Member Income, Plus the $200,000 Disabled Veteran Assessment Reduction
Updated April 2026
South Dakota provides a senior assessment freeze under SDCL Chapter 10-6A. Eligible homeowners age 65+ (or disabled) with single-member household income under $35,000 or multi-member household income under $45,000 can lock the assessed value of their primary single-family dwelling at the year-of-qualification level. Income limits are indexed annually beginning January 1, 2023 — by the greater of CPI or the annual change in federal Social Security payments. Separately, SD provides a $200,000 assessed-value reduction for veterans rated 100% permanently and totally disabled from service-connected disability, with no income test. Annual reapplication required for the senior freeze; the deadline is April 1 of each assessment year.
Senior Assessment Freeze (SDCL 10-6A): Eligibility
- Age 65 or older (or disabled with appropriate certification).
- Household income under $35,000 if single-member household, OR under $45,000 if multi-member household. Limits are indexed annually beginning January 1, 2023.
- Owner of a single-family dwelling used as primary residence.
- SD resident for at least the prior calendar year.
Mechanic: SD's Treasurer certifies eligibility and freezes the assessed value of the qualifying senior's dwelling at the year-of-qualification level. Subsequent assessment increases driven by reassessment don't flow through to the senior's assessed value used for tax computation. The freeze stays in place as long as the senior continues to qualify under the income test.
SD requires annual reapplication by April 1 with updated income documentation — similar to Illinois's PTAX-340 pattern. Missing the April 1 deadline terminates the freeze for that year, and re-qualification in a later year locks at the then-current assessed value (typically much higher than the originally-frozen amount). Calendar the deadline aggressively.
Is your South Dakota assessment defensible before the freeze locks?
The freeze locks at the year of initial qualification. If your assessment was inflated when you froze, you locked in too high a base. An assessment review before initial qualification matters disproportionately.
100% Disabled Veteran Reduction: $200,000 of Assessed Value, No Income Test
Veterans rated 100% permanently and totally disabled from service-connected disability — and surviving spouses of qualifying veterans — receive a $200,000 reduction in assessed value on their primary residence. No income test. Apply via the county Director of Equalization with VA documentation of the 100% rating attached.
For a 100% rated veteran with a $300,000 home, the reduction means tax is computed on $100,000 of assessed value rather than $300,000 — a 67% effective tax cut. For a home valued at or below $200,000, the DV reduction zeros out the property tax in practice. Surviving spouses retain the reduction under conditions specified in SDCL Title 10.
Frequently Asked Questions
My South Dakota multi-member household income is $48,000. Do I qualify for the senior freeze?
Possibly — depends on the indexed income limit for the current year. The base limits ($35,000 single / $45,000 multi-member) are indexed annually starting January 1, 2023, by the greater of CPI or the annual change in federal Social Security payments. By the 2026 cycle, the multi-member limit may be in the $48,000-$52,000 range depending on cumulative inflation adjustments since 2023. Check the current SD DOR Assessment Freeze page or contact your county Treasurer for the specific 2026 figures. If you're in the band, file by April 1 — you'll need to refile annually with updated income documentation.
I missed the April 1 SD reapplication deadline last year. Can I recover my prior freeze base?
No — the prior freeze base is gone for the year you missed. Reapplying at the next April 1 will re-establish the freeze, but at the current assessed value (the value as of the new January 1 assessment date), not at your original locked value. So if your home's assessed value rose 25% during the gap year, your re-established freeze locks at the higher current value going forward. The annual reapplication discipline is how SD's freeze works structurally; missing one cycle permanently raises your locked-in base. Calendar April 1 firmly.
If I'm a 100% rated SD veteran, do I need to also apply for the senior freeze?
Probably not — the $200,000 disabled veteran reduction is materially more generous than the senior freeze for most home values, and it has no income test (vs. the senior freeze's $45,000 multi-member cap). For a $300,000 home, the DV reduction shields $200,000 of value (tax computed on $100,000), while the senior freeze just locks the $300,000 assessment in place. Run both calculations: in the rare case where you have a very high-value home and modest income, the senior freeze could compound onto the DV reduction in ways worth examining — but for most 100% rated SD veterans, the DV path alone produces the better outcome.
