How Your South Dakota Paycheck Works
Since South Dakota is one of seven states with no personal income tax, FICA and federal income taxes are the only concern for workers here. The lack of income taxes means more money in your pocket throughout the year.
When we talk about FICA taxes, the two factors at play are Social Security and Medicare taxes. Each pay period, 6.2% of your paycheck goes to your share of Social Security taxes and 1.45% goes to Medicare taxes. Your employer matches these contributions so the total amount is double what you pay.
While most of the time you only pay 50% of the total FICA taxes, this is not always the case. If you’re a self-employed individual in the Mount Rushmore State, you’ll need to pay all FICA taxes yourself since you won’t have an employer to match the remaining half. If you do pay the full tax, make sure to look into the deduction of half the FICA taxes on your tax return (you will need to attach Schedule SE to your 1040).
Each time you receive a South Dakota paycheck, you will notice a federal income tax withholding. The amount of federal income tax that your employer withholds from your paycheck depends largely on the information you provide on the W-4 form you submit. This is why employers require you to submit a W-4 when you start a new job. You should also submit a new W-4 to reflect any updates to your filing status, dependents or salary. If you haven't recently, make sure to double-check your withholdings on your Form W-4.
Over the last few years, the IRS has made changes to the W-4. The new form removes the use of allowances and applies a five-step process that asks filers to indicate any additional income or jobs, along with other personal information.
As mentioned above, South Dakota does not have a state income tax. There also aren’t any local income taxes. This makes South Dakota a generally tax-friendly state. It also has one of the lowest sales taxes in the nation, with a base sales tax rate of just 4.5%, though municipalities may impose a general municipal sales tax rate of up to 2%, and an additional 1% municipal gross receipts tax (MGRT).

How You Can Affect Your South Dakota Paycheck
While you can’t avoid federal income taxes altogether even living in a tax-friendly state like South Dakota, you can take some steps that affect how much you pay. You can no longer claim allowances on your W-4, but you can elect to maximize your paycheck by contributing more to a 401(k) or another type of retirement account. This is because the money you put into a 401(k) or 403(b) is taken from your wages before taxes are applied. In other words, increasing your retirement contributions can actually lower your taxable income.
Putting funds into a health savings account (HSA) or flexible spending account (FSA), if your employer offers them, works in a similar fashion. You can use the funds you put into these accounts for health-related expenses, like medical copays or prescriptions. However, it's important to keep in mind that there is an expiration date on money you put into an FSA. Only $500 will roll over from year to year.
