The South Dakota Paycheck Calculator estimates your take-home pay in one of only nine states that does not impose a state income tax on any form of personal income. South Dakota does not tax wages, salaries, tips, bonuses, commissions, investment income, retirement income, or any other form of personal income. Workers in South Dakota see only federal income tax and FICA (Social Security and Medicare) deducted from their paychecks, making it one of the simplest states for paycheck calculations. South Dakota's lack of income tax is sustained by other revenue sources including a 4.5% state sales tax (plus municipal additions up to approximately 6.5% total), property taxes, tourism taxes (particularly from the Sturgis motorcycle rally and Mount Rushmore tourism), and revenue from the state's trust and financial services industry. The state also benefits from significant agricultural revenue. South Dakota does not impose any local income taxes, payroll taxes, or mandatory employee-funded disability or family leave insurance programs. Compared to neighboring states, South Dakota offers a significant tax advantage. Minnesota charges rates up to 9.85% (one of the highest in the nation), Nebraska ranges up to 5.84%, Iowa has moved to a 3.8% flat tax, North Dakota charges up to 2.5%, Montana ranges up to 6.75%, and Wyoming also has no income tax. For workers along the South Dakota-Minnesota border (particularly the Sioux Falls metro area), the difference is dramatic: a worker earning $80,000 saves approximately $4,000 or more annually by working in South Dakota rather than Minnesota. This calculator serves all South Dakota workers, from the financial services professionals in Sioux Falls (home to major credit card operations including Citibank and Wells Fargo), to healthcare workers at Sanford Health and Avera Health, to agricultural workers across the state's vast farming and ranching operations, to tourism and hospitality workers in the Black Hills region.
Net Pay = Gross Pay - Federal Income Tax - FICA (Social Security + Medicare) - Pre-Tax Deductions South Dakota State Income Tax: $0 (no state income tax) No Local Income Tax No State Payroll Taxes No State Disability Insurance No State Family Leave Insurance FICA: 6.2% Social Security (up to $168,600 in 2024) + 1.45% Medicare (no cap) + 0.9% Additional Medicare Tax on wages over $200,000
- 1Enter your gross pay amount and select your pay frequency. South Dakota employers use standard pay schedules including weekly, biweekly, semi-monthly, and monthly. Your gross pay includes base salary, overtime, bonuses, commissions, and taxable fringe benefits. South Dakota's minimum wage is $11.20 per hour as of 2024, indexed to inflation. For tipped employees, the minimum cash wage is $5.60 per hour.
- 2The calculator applies federal income tax withholding based on your W-4 form elections. Since South Dakota has no state income tax, your W-4 settings only affect federal withholding. Your filing status, dependents, and additional withholding amounts determine federal tax deductions. The 2024 federal brackets range from 10% to 37%, with the standard deduction of $14,600 (single) or $29,200 (MFJ).
- 3FICA taxes are calculated on your gross wages. Social Security at 6.2% on the first $168,600, Medicare at 1.45% on all wages, plus the additional 0.9% Medicare surtax on wages over $200,000. These calculations are the same in every state.
- 4Since South Dakota has no state income tax, the calculator skips the state tax calculation entirely. There are also no local income taxes, city taxes, county taxes, transit taxes, or any other form of income-based payroll deduction at the state or local level. The only mandatory deductions are federal income tax and FICA.
- 5Subtract voluntary pre-tax and post-tax deductions including 401(k) contributions, health insurance premiums, HSA contributions, and FSA contributions. In South Dakota, pre-tax deductions reduce only your federal tax liability (since there is no state tax to reduce). Post-tax deductions include Roth contributions, after-tax insurance, and any wage garnishments.
- 6The calculator produces your net take-home pay. South Dakota workers retain a higher percentage of their gross pay than workers in most other states. A single filer earning $60,000 pays approximately $5,400 in federal tax and $4,590 in FICA, totaling $9,990 or 16.7% of gross pay. The same worker in neighboring Minnesota would pay an additional $3,200 or more in state income tax.
- 7Use the calculator to compare scenarios and optimize your federal withholding. Since there is no state tax planning needed, South Dakota workers can focus entirely on federal tax optimization through 401(k) contributions, HSA maximization, and proper W-4 elections.
Gross biweekly pay is $2,769.23. Pre-tax 401(k) at 6% equals $166.15. Federal taxable income: $53,080. Federal tax: approximately $260 per period. No SD state tax. FICA: $171.69 (SS) plus $40.15 (Medicare) equals $211.84. Total deductions: $166.15 (401k) plus $260 (federal) plus $211.84 (FICA) equals $637.99. Net pay: approximately $2,131.24.
Gross biweekly pay is $2,230.77. Federal tax after MFJ deduction and child credits: approximately $35 per period. No SD state tax. FICA: $138.31 (SS) plus $32.35 (Medicare) equals $170.66. Total deductions: approximately $205.66. Net pay: approximately $2,025.11.
Gross biweekly pay is $1,846.15. Federal tax: approximately $108 per period. No SD state tax. FICA: $114.46 (SS) plus $26.77 (Medicare) equals $141.23. Total deductions: approximately $249.23. Net pay: approximately $1,596.92.
Financial services workers in Sioux Falls, which is home to major credit card and banking operations (Citibank, Wells Fargo, First Premier Bank, Meta Financial Group), use this calculator to understand their tax-advantaged compensation. South Dakota's lack of income tax was a key factor in attracting these financial institutions to the state, and workers benefit from keeping 100% of their state tax savings compared to colleagues at the same companies' offices in higher-tax states.
Healthcare workers at Sanford Health and Avera Health, two of the largest employers in South Dakota, use the calculator for payroll verification and financial planning. These healthcare systems employ thousands of nurses, physicians, and support staff across the state. The no-income-tax environment makes South Dakota healthcare positions financially competitive despite sometimes lower nominal salaries than positions in coastal cities.
Agricultural workers and farm operators across South Dakota's vast farming and ranching landscape use the calculator to plan finances around variable seasonal income. South Dakota is a leading producer of corn, soybeans, wheat, and cattle. Farm income can fluctuate dramatically based on commodity prices and weather. The absence of state income tax means this variability only affects federal tax planning.
Workers considering relocation from high-tax states use this calculator to quantify the income tax savings of moving to South Dakota. The state has actively marketed its tax-friendly environment to attract businesses and remote workers. A worker earning $100,000 moving from Minnesota saves approximately $5,500 in state income tax, while one from California saves approximately $6,000-$8,000.
Cross-Border Workers in the Sioux Falls-Minnesota Region
The Sioux Falls metro area is near the Minnesota border, and some workers commute between the two states. South Dakota residents who work in Minnesota owe MN income tax (up to 9.85%) on their MN-source wages with no offsetting credit from SD. Workers who can secure employment on the South Dakota side of the border save thousands annually. A $75,000 earner working in SD rather than MN saves approximately $3,500 per year in state income tax.
Trust and Financial Services Industry Workers
South Dakota has become a major center for the trust and financial services industry, partly due to its favorable tax and trust laws. Workers in this industry (trust administrators, financial advisors, compliance officers) often earn above-average salaries and benefit significantly from the state's no-income-tax policy. The trust industry has brought sophisticated financial services jobs to Sioux Falls and other SD cities.
Sturgis Rally and Seasonal Tourism Workers
The annual Sturgis Motorcycle Rally and Black Hills tourism generate significant seasonal employment. Workers who come to South Dakota temporarily for these events from other states do not owe SD income tax on their earnings (since SD has none). However, they may owe income tax to their home state on their SD-earned income. Local businesses that hire seasonal workers benefit from simplified payroll since there is no state withholding to manage.

Does South Dakota have any state income tax?
No. South Dakota does not impose any state income tax on any form of personal income. This includes wages, salaries, tips, bonuses, investment income, retirement distributions, Social Security, pension income, and capital gains. South Dakota is one of nine states with no state income tax.
Are there any local income taxes in South Dakota?
No. No city, county, or local jurisdiction in South Dakota imposes any form of income tax. The only mandatory paycheck deductions are federal income tax and FICA.
How does South Dakota fund government without an income tax?
South Dakota relies on sales tax (4.5% state rate plus local additions), property taxes, tourism-related taxes, and revenue from the financial services and trust industry. The state also benefits from federal payments, gaming revenue, and a relatively low cost of government operations. South Dakota has consistently maintained balanced budgets without an income tax.
If I live in Sioux Falls and work in Minnesota, do I pay Minnesota tax?
Yes. Minnesota taxes income based on where the work is performed. If you commute from Sioux Falls to a job in Minnesota, you owe Minnesota income tax on your MN-source wages. South Dakota has no income tax to offset, so you effectively pay the full Minnesota rate with no credit available. This situation makes the location of your employer critically important in the Sioux Falls-southwestern Minnesota region.
Is South Dakota a good state for retirees from a tax perspective?
Yes. South Dakota does not tax any form of retirement income including Social Security, pensions, 401(k) distributions, IRA withdrawals, and capital gains. Combined with no state income tax on any other form of income, South Dakota is one of the most tax-friendly states for retirees. The state's lower cost of living compared to coastal areas further enhances the purchasing power of retirement income.
เคล็ดลับโปร
If you work in the Sioux Falls area and receive job offers from both South Dakota and Minnesota employers, always calculate the after-state-tax compensation. A $75,000 job in Sioux Falls yields approximately $3,500 more in annual take-home pay than the same salary in a Minnesota border town like Luverne or Worthington. This difference should be a key factor in employment decisions, especially since the cost of living is comparable on both sides of the border.

South Dakota's lack of state income tax has made it an unlikely financial services powerhouse. The state's favorable tax and trust laws have attracted over $800 billion in trust assets, making it one of the largest trust jurisdictions in the world. Major banks including Citibank moved their credit card operations to Sioux Falls in the 1980s after South Dakota eliminated its usury laws and offered the tax-free environment. Today, the financial services industry is one of the largest employers in the state, providing thousands of well-paying jobs in an unlikely Great Plains location.
