If a SD landowner did not return a county classification questionnaire in 1992, had his land reclassified from agricultural to non-agricultural for the 1993 tax year, paid the higher 1993 taxes in 1994 without protest, and later asks for an abatement and refund under SDCL chapter 10-18, can he get it?
Plain-English summary
Mr. X owned property in a SD county. In 1992, the county director of equalization sent questionnaires to landowners asking them to confirm property classifications. Mr. X did not respond. His property was reclassified from agricultural to non-agricultural for the 1993 assessment, which raised his school tax bill because agricultural land is taxed at lower levies than non-agricultural land under SDCL 10-12-31. Mr. X paid the 1993 taxes when they came due in 1994 without protest. Then in June 1994 he requested an abatement and refund under SDCL chapter 10-18, arguing that his property had always been agricultural and that he had requalified for the classification in 1994.
The 1994 AG said no, the abatement was not available.
The reasoning runs through two layers. First, SDCL 10-18-1 lists six specific situations where abatement is available: identifying-entry errors, improvements that did not exist at the time of assessment, exempt status, no taxable interest, payment-recording errors, and duplicate assessment. The list is exclusive (the statute says "in the following cases only"). Reclassification disputes are not on the list. Valuation disputes are also not on the list. The abatement procedure is a narrow remedy for clerical and structural errors, not a do-over for missed appeals.
Second, the proper path for classification and valuation disputes is the equalization process under SDCL chapter 10-11. SDCL 10-11-16 and SDCL 10-11-26 give local and county boards of equalization authority over both valuation and classification. A taxpayer who disagrees with how his property has been classified must take the dispute to the equalization board. Mr. X did not. He also did not pay under protest and bring a refund lawsuit under SDCL 10-27-2 (the Riverview Properties path). Neither route was used, so neither route remains available.
The exhaustion principle is settled SD law. Yusten v. Morrison (1960) restates the long-standing rule: "before a taxpayer may apply for judicial relief from an alleged error in valuation he must exhaust his remedies before the boards of equalization empowered to correct the error." The AG cited a string of his predecessors' opinions (AGR 79-14, AGR 1955-56 p. 201, AGR 1947-48 p. 39, AGR 1923-24 p. 352) all reaching the same conclusion: classification and valuation issues are equalization matters, not abatement matters.
The bottom line: a taxpayer who skips the equalization appeal cannot use SDCL chapter 10-18 abatement to revisit the issue later. The two procedures cover different things. Mr. X's only remaining avenue (if any) would be a future-year appeal during the next equalization cycle; the 1993 taxes are paid and final.
Currency note
This opinion was issued in 1994. Subsequent statutory amendments, court decisions, or later AG opinions may have changed the analysis. Treat this page as historical context, not current legal advice. Verify current law before relying on any specific rule, deadline, or remedy mentioned here. SDCL chapters 10-11 and 10-18 have been amended since 1994, including changes to the abatement categories and the equalization procedure timing. The general principles (abatement is narrow, equalization is the proper channel for classification and valuation appeals, taxpayers must exhaust equalization remedies) have remained stable, but specific statutory citations and procedural details should be checked against current law.
What the opinion meant at the time
For SD county commissioners receiving abatement petitions in the 1990s, the opinion provided a clear screening rule. If the petition raised a classification or valuation issue, the petition should be denied because abatement is the wrong tool. The petitioner should be redirected to the equalization process for future tax years.
For SD county directors of equalization, the opinion confirmed that their decisions on classification and valuation were the final word at the county level, subject only to circuit court review through the proper equalization channels.
For SD property tax attorneys, the opinion reinforced the importance of advising clients to file equalization appeals on time. Missing the equalization window forecloses the ability to challenge classification or valuation, and abatement cannot fill the gap.
For SD agricultural landowners who had previously skipped equalization appeals, the opinion was bad news. The 1993 tax liability stood. The only path forward was to ensure proper classification going forward.
For SD school districts dependent on property tax revenue calibrated to classification, the opinion preserved revenue stability. A taxpayer cannot retroactively reduce his tax liability by skipping the appeal process and then claiming abatement.
Common questions
Q: What is the difference between abatement and equalization?
A: Abatement under SDCL chapter 10-18 is a narrow refund mechanism for the six specific errors listed in SDCL 10-18-1 (entry error, nonexistent improvements, exempt status, no taxable interest, payment errors, duplicate assessment). Equalization under SDCL chapter 10-11 is the regular annual process for adjusting valuation and classification.
Q: What are the six abatement categories?
A: (1) Error in identifying entry or description of property; (2) Valuation included improvements that did not exist at assessment time; (3) The complainant or property is exempt; (4) The complainant had no taxable interest at assessment time; (5) Erroneous payment or receipt error; (6) Property assessed against the complainant more than once in the same year.
Q: Why isn't classification a category?
A: The Legislature did not include it. Classification disputes have to go through equalization. SDCL 10-18-1 says "in the following cases only," and classification is not on the list.
Q: What is the equalization deadline?
A: The equalization process has specific timing under SDCL chapter 10-11. A taxpayer who wants to challenge classification or valuation has to act within the window for that tax year. Missed deadlines forfeit the appeal.
Q: What is the payment-under-protest procedure?
A: SDCL 10-27-2 lets a taxpayer pay the disputed taxes under written protest and then sue for refund. Riverview Properties, Ltd. v. State Board of Equalization is the leading case. This is the alternative to the equalization-board route.
Q: Can a taxpayer challenge classification in court without first going to the equalization board?
A: No. Under Yusten v. Morrison and consistent case law, equalization remedies must be exhausted before judicial relief is available.
Q: What happens if the taxpayer pays without protest?
A: The taxpayer has waived the payment-under-protest route. The remaining option (equalization for future years) does not retroactively reduce the prior year's tax.
Q: Could the county commission grant an abatement out of compassion even though the case does not fit SDCL 10-18-1?
A: No. The abatement statute lists the exclusive categories. Granting an abatement outside those categories would be ultra vires.
Background and statutory framework
South Dakota property tax law separates two distinct remedial channels. The equalization process under SDCL chapter 10-11 is the front-end check on the assessor's work. Each year, local and county boards of equalization meet to consider classification and valuation challenges. Taxpayers must bring complaints during the equalization window, which is the same year the assessment is being made.
The abatement process under SDCL chapter 10-18 is a narrow back-end remedy for specific errors that fall outside the equalization framework. The six categories in SDCL 10-18-1 are mostly clerical or structural (description error, ghost improvements, exempt status, no taxable interest, payment-recording problems, duplicate assessment). They do not cover discretionary classification or valuation decisions made by the assessor.
The reason for the separation is institutional. Equalization is where the local taxing system applies its expertise to valuation and classification questions. Boards of equalization include local officials familiar with land use and market conditions in the area. The abatement process, by contrast, is a routine administrative tool for fixing data-entry errors and similar issues. It is not designed to second-guess equalization decisions.
The exhaustion-of-remedies rule reinforces the separation. If a taxpayer could skip equalization and go straight to abatement (or to court), the equalization process would be optional. The Yusten v. Morrison line of cases prevents that workaround.
The 1994 AG's analysis is consistent with at least 70 years of prior AG opinions reaching the same conclusion. The agency's institutional position has been stable since the 1920s: equalization is the channel for valuation and classification disputes; abatement is not.

OFFICIAL OPINION NO. 94-16
Abatement of Taxes
Dear Mr. Buskerud:
You have requested an official opinion of this Office based upon the following facts:
FACTS:
In 1992, the county director of equalization reviewed the classification of various agricultural parcels, sending out questionnaires to landowners. Mr. "X" did not return his questionnaire. His property was reclassified as non-agricultural for the 1993 assessment. Mr. "X" paid the 1993 taxes in 1994 when due, without protest. In June of 1994, Mr. "X" requested an abatement/refund under SDCL ch. 10-18 due to his requalifying for the agricultural classification in 1994 and his allegations that the property has always been agricultural. Mr. "X" was not before the county board of equalization in 1993 or 1994.
Based upon the foregoing facts, you have asked the following question:
QUESTION:
Is Mr. "X" entitled to an abatement/refund of his 1993 taxes?
Local and county boards of equalization have the authority to address not only the valuation of a particular parcel of property, but also the classification of that parcel as agricultural or non-agricultural. See SDCL §§ 10-11-16 and 10-11-26. The classification of a parcel of property as agricultural or non-agricultural is of significant importance when applying the school tax levy to the property. SDCL 10-12-31.
Under the facts presented, the property owner did not participate in the equalization process for either 1993 or 1994. Nevertheless, the property owner wishes to have an abatement pursuant to SDCL ch. 10-18, with the abatement presumably calculated on the difference in taxes if the property had been classified as agricultural, versus the non-agricultural classification applied by the county. Further, it does not appear that the property owner availed himself of the payment under protest and lawsuit for refund provision. SDCL 10-27-2; Riverview Properties, Ltd. v. State Board of Equalization, 439 N.W.2d 820 (S.D. 1989).
The statutory provisions for abatement are very specific:
Unless otherwise expressly provided, if any person against whom an assessment has been made or a tax levied, claims such assessment or tax or any part thereof to be invalid for any reason herein stated, the same may be abated, or the tax refunded if paid, and the board of county commissioners is authorized and empowered to abate or refund, in whole or in part, such invalid assessments or taxes in the manner hereinafter prescribed and in the following cases only:
(1) When an error has been made in any identifying entry or description of the property, in entering the valuation thereof or in the extension of the tax, to the injury of the complainant;
(2) When improvements on any real property were considered or included in the valuation thereof, which did not exist thereon at the time fixed by law for making the assessment;
(3) When the complainant or the property is exempt from the tax;
(4) When the complainant had no taxable interest in the property assessed against him at the time fixed by law for making the assessments;
(5) When taxes have been erroneously paid or error made in noting payment or issuing receipt thereof;
(6) When the same property has been assessed against the complainant more than once in the same year, and the complainant produces satisfactory evidence that the tax thereon for such year has been paid; provided that no tax shall be abated on any real property which has been sold for taxes, while a tax certificate is outstanding. [Emphasis added.]
SDCL 10-18-1. Unless an individual specifically comes within one of the six categories outlined above in SDCL 10-18-1, no abatement or refund of taxes is available under that section. I should also note that SDCL 10-18-1 is not mandatory ("the same may be abated, or the tax refunded if paid").
From the facts you have presented, it is clear that the property owner does not come within one of the six categories of SDCL 10-18-1. The property owner is attempting to replace the equalization provisions of SDCL ch. 10-11 with the abatement provisions of SDCL ch. 10-18 because the property owner did not avail himself of the equalization provisions.
The South Dakota Supreme Court has examined this very issue several times. In Yusten v. Morrison, 103 N.W.2d 653 (S.D. 1960), the Court reaffirmed the rule "that before a taxpayer may apply for judicial relief from an alleged error in valuation he must exhaust his remedies before the boards of equalization empowered to correct the error." Numerous other South Dakota cases following this proposition were cited. Yusten, 103 N.W.2d at 655. Therefore, an equalization issue, such as valuation or classification, first must be brought before a local board of equalization empowered to decide those issues. SDCL §§ 10-11-16 and 10-11-26.
My predecessors also have addressed this issue and have uniformly stated that equalization issues (valuation, classification, etc.) are not grounds for an abatement or a refund. AGR 79-14; AGR 1955-56 p. 201, 202; AGR 1947-48 p. 39, 40; AGR 1923-24 p. 352.
To summarize, an individual seeking an abatement must specifically fall within one of the six categories of SDCL 10-18-1. A person seeking redress for an equalization issue, either valuation or classification, must do so within the context of the equalization provisions of SDCL ch. 10-11. The abatement provisions of SDCL ch. 10-18 are not available to contest the classification of a parcel of property.
