South Dakota Department of Labor and Regulation calculates your weekly benefit at approximately 1/26 of your wages in your highest base period quarter, capped at $553 per week with a minimum of $28 per week. South Dakota's no-state-income-tax status means UI benefits are only subject to federal income tax — consider requesting voluntary 10% federal withholding ($41/week) to avoid a tax surprise when you file your federal return. At $553/week for 26 weeks, South Dakota's total maximum potential benefit is $10,764. Agricultural, meat-processing, and healthcare workers — South Dakota's major wage earners — often produce high-quarter wages that push benefits toward the $553 cap.
- Weekly benefit ≈ 1/26 of highest base period quarter wages, capped at $553/week, minimum $28/week.
- No South Dakota state income tax on UI. Federal 10% withholding option available through South Dakota UI.
- Appeal monetary determination within 10 days of mailing date if base period wages appear incorrect.

Reading Your South Dakota UI Monetary Determination
South Dakota UI generates your monetary determination after you file, showing your weekly benefit amount, total maximum benefit, and benefit year. South Dakota's formula uses 1/26 of your highest-earning base period quarter. At $10,764 in your high quarter, 1/26 = $553/week — hitting the cap. Review the quarterly wage figures against your W-2 and appeal within 10 days of the mailing date if wages from any employer are missing or incorrect.
Frequently Asked Questions
- I earned $75,000 at a Sioux Falls company. Why is South Dakota UI only $553/week?
- South Dakota's $553/week statutory cap applies regardless of prior income. At $75,000 annually, your high quarter contains approximately $18,750. South Dakota's 1/26 formula produces $18,750 ÷ 26 = $721/week — capped at $553. Over 26 weeks, your total South Dakota UI is $10,764 — about 14% of your $75,000 annual income. South Dakota's $553 cap is set by state law and can't be exceeded. The advantage of South Dakota's no-income-tax status is that you keep the full federal after-tax value of each $553 without a separate South Dakota state tax bite. Budget carefully while searching — South Dakota's low unemployment rate typically means faster reemployment in Sioux Falls, Rapid City, and Aberdeen than in higher-unemployment states.
- I worked summer agricultural jobs in South Dakota — can those wages count in my South Dakota UI base period?
- Agricultural wages count in South Dakota's base period if your agricultural employer met South Dakota's coverage threshold (10 or more full-time-equivalent workers in at least 20 weeks, or $20,000+ in quarterly agricultural wages). Wages from excluded small farms don't appear in South Dakota's quarterly wage records. If your agricultural employer met the threshold, their wages appear in your South Dakota UI monetary determination's quarterly breakdown. Verify the quarters by comparing to your pay stubs from summer agricultural work. If qualifying agricultural wages are missing from your South Dakota UI determination, contact South Dakota Department of Labor and Regulation with your wage documentation and appeal within 10 days of the mailing date.
- South Dakota UI shows $28/week minimum for me. I worked nearly a full year at a Brookings, SD job. Something seems wrong.
- $28/week with a year of employment is clearly an error. At minimum wage ($11.20/hour in South Dakota as of 2025) for 40 hours/week, a year produces approximately $23,296 in wages — and a high quarter of $5,824. South Dakota's 1/26 formula: $5,824 ÷ 26 = $224/week — far above the $28 minimum. Contact South Dakota Department of Labor and Regulation immediately and appeal within 10 days of the mailing date. Bring your W-2 and pay stubs showing quarterly wages. The likely cause: your employer filed quarterly wage reports late or missed a quarter entirely. South Dakota Department of Labor and Regulation can contact your employer for corrected quarterly reports and recalculate your monetary determination accordingly.
- I had wages from South Dakota and North Dakota in my base period. Which state's South Dakota UI should I file with?
- File with the state where you have the highest wages or where you currently reside — South Dakota Department of Labor and Regulation allows combined wage claims that include North Dakota wages in the base period calculation. File through South Dakota UI at dlr.sd.gov/ra and disclose your North Dakota wages — South Dakota will aggregate wages from both states and apply South Dakota's formula. If combined total base period wages produce $553/week under South Dakota's formula, that's your benefit. Alternatively, North Dakota's $815/week maximum may produce a higher benefit if your North Dakota wages were substantial — compare both states before choosing. File in the state that produces the higher weekly benefit or where you're most likely to search for work.
- My South Dakota UI calculation seems low because I had a month-long gap between my last two jobs. How does that affect my base period?
- A month-long employment gap during the base period reduces the total wages in the affected quarters. South Dakota's formula uses your highest single base period quarter — so a gap that only affects the weaker quarters doesn't hurt your high-quarter calculation. If the gap falls entirely within one quarter (say, one month off in Q2), Q2's wages are lower but Q3's wages (your high quarter, if you worked through Q3) are unchanged. If the gap straddles two quarters, both are reduced. The high-quarter identification is the key: look at all four base period quarters and identify which has the most wages — that's your South Dakota UI formula input, regardless of gaps in other quarters. Contact South Dakota Department of Labor and Regulation if your monetary determination doesn't identify the correct high quarter based on your actual work history.
