South Dakota Alimony / Spousal Support Calculator
Estimate alimony/spousal support in South Dakota. Calculate monthly payments based on income, marriage length, and South Dakota guidelines.
How This Calculator Works
Calculation methodology and assumptions
South Dakota alimony calculations consider the income difference between spouses, marriage duration, and family circumstances. Common guidelines use 30-35% of the income difference (25% if there are minor children, since child support is also paid). Duration is typically proportional to marriage length: short marriages (<10 years) get 3-5 years of support, medium (10-20 years) get 5-15 years, and long marriages (20+ years) may receive permanent/indefinite support.
Key State Information
South Dakota uses judicial discretion in setting alimony, considering multiple factors. Since South Dakota has no state income tax, alimony payments don't affect state tax liability. Note: Alimony is no longer deductible for federal taxes (post-2018 TCJA).
