South Dakota authorizes alimony under S.D. Codified Laws § 25-4-41. It is available as part of a divorce case. South Dakota does not publish a statewide alimony calculator. It also does not publish a fixed duration formula. The amount and length of any award are left to the discretion of the circuit court, based on the specific financial circumstances of the marriage. South Dakota's legislative website renders its statute text through an interactive application. That application could not be accessed directly for this page. The description below reflects the general, well-established framework of South Dakota alimony law. Confirm the current statutory factor list, and any recent amendments, directly on the South Dakota Legislature's website, or with the clerk of courts in the county where your case is filed. The broad outlines of South Dakota's discretionary approach are well established even where the exact statutory wording needs direct confirmation.

South Dakota courts generally weigh several factors when deciding alimony. These include the length of the marriage, and the respective ages and health of the parties. They include each spouse's earning capacity and financial condition. They also include the standard of living established during the marriage.
The exact current statutory language could not be independently confirmed for this page. Treat this as a general description of the framework, not a verbatim quote of the statute. South Dakota's approach here is broadly consistent with the factor-based standard most states use, weighing the marriage's length and each spouse's financial position rather than assigning fault or running a set calculation.
South Dakota does not appear to divide alimony into separate named categories, such as rehabilitative or transitional support, the way some states do. Based on the general framework, South Dakota courts have discretion to structure an award as periodic payments or otherwise, depending on what fits the facts of the case. The statute's exact current text could not be verified for this page. Confirm with the South Dakota Legislature's website whether any named categories or structural options exist in the current law before assuming this description is complete.
Some states, like New York or Texas, have a legislatively defined formula or income cap for alimony. South Dakota does not work that way. Every award is the product of the circuit court's individual weighing of the facts in that case. This means outcomes can vary significantly from one case to another, even between cases with similar income levels on both sides.
Without a published formula to point to, both spouses in a South Dakota divorce are generally better served by documenting their specific financial circumstances clearly. How the judge weighs those facts decides the case, not a set calculation.
Whether a South Dakota alimony order can later be modified depends on two things. It depends on the current statutory language, and it depends on the terms of the individual decree. That specific text could not be verified for this page.
Confirm the current modification standard, and any duration rules, with the South Dakota Legislature's website. You can also confirm with the clerk of courts before assuming a particular outcome applies to your case. Because South Dakota's framework leans so heavily on judicial discretion, the terms written into your specific decree matter more than they might in a state with a detailed statutory modification standard.
Divorce cases in South Dakota, including any request for alimony, are filed in the circuit court for the county where one of the spouses resides. South Dakota has residency requirements that generally must be met before a case can be filed there in the first place, so confirm eligibility to file before starting the paperwork or scheduling anything with the court. The Unified Judicial System publishes general self-help materials for people handling a divorce without an attorney. The clerk of courts in the relevant county is typically the best source for confirming current local filing procedures and forms.

Not independently confirmed
No. South Dakota does not publish a statewide formula or calculator for alimony. The circuit court decides the amount and duration case by case, based on the specific facts of the marriage.
Courts generally look at the length of the marriage, each spouse's age and health, earning capacity and financial condition, and the standard of living established during the marriage, though the exact current statutory wording should be confirmed directly with the South Dakota Legislature's website.
There is no fixed statutory duration formula. The length of an award depends on the facts of the case as weighed by the circuit court, so confirm the current rules and any recent legislative changes before assuming a specific outcome.
This depends on the current statutory language and the terms of your specific decree. Confirm the modification standard with the South Dakota Legislature's website or the clerk of courts.
Under federal law, for agreements executed after December 31, 2018, alimony is not deductible by the paying spouse and not taxable to the recipient. This is a federal Tax Cuts and Jobs Act rule and applies in South Dakota the same as in every other state.
