How to Appeal Your Property Tax in South Dakota: Step-by-Step Guide for 2026

In South Dakota a value appeal starts with a written notice to the clerk of your local board of equalization (the township or city board), due no later than the Thursday before the third Monday in March (SDCL 10-11-16). Where your jurisdiction has a consolidated board instead, the notice goes to the county auditor by the first Tuesday in April (10-11-67).

South Dakota appeal deadlines by step

The 2026 column comes from the Department of Revenue’s 2026 Property Owner Appeal Process Guide. Those dates have all passed; the next cycle starts with the notice mailed by March 1, 2027. An appeal to the local board (10-11-16), an appeal from the local board to the county board (10-11-23), a complaint to a consolidated board (10-11-67) and an appeal to the Office of Hearing Examiners (10-11-42) may be mailed, and each of those sections says “the postmark shall be conclusive evidence regarding the timeliness of the appeal.” Three steps have no postmark rule. A nonresident owner who goes straight to the county board without a local board complaint must perfect the appeal “by filing a written notice of appeal with the county auditor on or before the first Tuesday in April” (10-11-23), and the Department of Revenue guide says “file” means “in the hands of the official with whom it is to be filed.” Both circuit court routes, straight from the county board and after the Office of Hearing Examiners, are taken by serving notice, and only the direct route from the county board also requires a $250 bond, as described below.

Which board you start with depends on where the parcel sits

Under 10-11-66, a county, its cities, school districts and townships may agree by resolution to merge the local and county boards into one consolidated board. Where they have, the first and only board-level step is the consolidated board, and the April deadline in 10-11-67 replaces the March one. The Department of Revenue guide says to “look on your assessment notice to see if this applies to your property.”

Where boards are not consolidated, 10-11-27 closes the door on skipping the local board: “No complaint concerning property assessed in any district having a local board of equalization shall be considered unless it has first been made to such local board.” The same sentence carves out one group: “a nonresident owner or nonresident taxpayer of the taxing district may be heard without such original complaint.” Owners in unorganized territory also go straight to the county board, which “has all the power and authority of a local board of equalization in all unorganized territories” (10-11-26).

What to send and what the local board does with it

The Department of Revenue guide says a written appeal “can be a letter, email, a signed PT17 form, or any other type of written notification.” It must include your name and the legal description of the property, and should include a short reason. At the hearing, the form PT17 must be completed, and the clerk will help if you appear in person. The guide also says “just stating the value is too high is not enough,” and suggests sales of similar properties and assessments of similar properties.

The appeal covers the whole parcel. Under 10-11-16, it “shall encompass the aggregate valuation of the property being appealed or the property classification.” The guide says an appeal of just the land or just the structure is treated as an appeal of the entire property. A lessee who pays the taxes under the lease counts as the taxpayer and can appeal.

Local boards meet on the third Monday of March (10-11-13) and must finish “within five consecutive days” (10-11-14). The board then notifies each appellant in writing “seven days after the adjournment” (10-11-16.1).

By the day the local board meets, the director of equalization delivers updated assessment records to the clerk, and they stay open to public inspection until the following Saturday (10-6-153). If your assessed value rose more than 20 percent without an addition, improvement or change in use or classification, 10-6-155 requires a separate notice. That notice must say the director will give you “sales of comparable property or other information supporting the increased assessed valuation” on request.

The county board in April

The county commissioners meet as the county board of equalization on the second Tuesday in April and may stay in session no longer than three weeks after that date (10-11-25). Appeals “shall be heard de novo” (10-11-26), so the county board decides the value fresh rather than reviewing the local board for error. Its written decision must be “postmarked on or before the Friday following its adjournment” (10-11-26.1). Two kinds of appeal go directly to the county board, according to the Department of Revenue guide: disputes over owner-occupied status and over taxable or exempt status.

After the county board: the Office of Hearing Examiners or circuit court, not both

Section 10-11-42 lets you appeal to the Office of Hearing Examiners by mailing or filing a notice with the chief administrative law judge in Pierre by the third Friday in May. The notice “shall state informally the substance of the decision appealed from and the grounds upon which appeal is taken.” That appeal is heard de novo as a contested case under chapter 1-26 (10-11-42.1), and a further appeal to circuit court runs under chapter 1-26 in the county where the property is (10-11-43). That appeal must be served on the adverse party, the agency and the hearing examiner, and filed with proof of service with the clerk of courts, “within thirty days after the agency served notice of the final decision” or, if a rehearing is authorized and requested, within thirty days after notice of the decision on it (1-26-31).

The alternative is to go from the county board straight to circuit court under 10-11-44, within thirty days of the published notice of the decision (10-11-26.1) or the written notice served on you, whichever occurred last. Section 10-11-44 says the appeal is filed “in the same manner and upon the same conditions and terms as other appeals may be taken from decisions of a board of county commissioners.” Those terms require “a bond in the amount of two hundred fifty dollars with one or more sureties to be approved by the county auditor” (7-8-27) and service of “written notice upon any county auditor or commissioner, upon the state’s attorney of that county, or upon any person appointed by the board pursuant to resolution to accept notice” (7-8-29). You cannot do both: “an appeal to either tribunal excludes an appeal to the other” (10-11-42). Before going to circuit court by either route, read 10-11-45.1. The circuit court may award disbursements, “including reasonable attorneys’ fees,” against an appellant who does not prevail.

The 2026 guide lists the mailing address for the Office of Hearing Examiners appeal as Chief Administrative Hearing Officer, 523 E. Capitol Ave, Pierre, SD 57501. It also notes that “the Department of Revenue is not involved in any OHE hearings or decisions.”

South Dakota appeal FAQ

I got my notice but missed the March local board deadline. Can I still go to the county board?

Not if your property is in a district with a local board and you live there. Under 10-11-27 the county board may not consider the complaint, and the Department of Revenue guide says an owner who skips the local board forfeits “their appeal rights to the remaining boards.” Nonresident owners and owners in unorganized territory are the stated exceptions.

Does an email count as a written appeal?

Yes, according to the Department of Revenue: “A written appeal can be a letter, email, a signed PT17 form, or any other type of written notification,” for local, county and consolidated boards alike.

Can I appeal only the value of my house and leave the land alone?

No. An appeal “shall encompass the aggregate valuation of the property being appealed or the property classification” (10-11-16). A land-only or building-only appeal is treated as an appeal of the whole parcel.

Can I take the county board’s decision to the Office of Hearing Examiners and circuit court at once?

No. Section 10-11-42 says “an appeal to either tribunal excludes an appeal to the other.” Pick one: the hearing examiners notice is due by the third Friday in May; a court appeal is due within the 30 days set by 10-11-44 and needs the $250 bond with sureties required by 7-8-27.

Who decides whether my home counts as owner-occupied?

An appeal of owner-occupied status goes directly to the county board of equalization, per the Department of Revenue guide. For 2026 it listed the conditions, including ownership and occupancy on November 1, 2025 and a certificate filed by March 15, 2026.
