Iowa Paycheck Quick Facts
How Your Iowa Paycheck Works
When you start a new job, you fill out a W-4 form and the information on this form tells your employer how much he or she should be withholding in taxes from each of your paychecks. Whether you are paid monthly or biweekly, your employers will take out federal income taxes from your wages. This money goes to the IRS who will put it toward your annual income taxes.
Want to know what affects your withholdings? Your marital and filing status is a big part of it. Whether you’re single or married and whether you’re filing jointly or separately or as the head of the household, will impact your income tax bracket. If you qualify as a common-law couple, you have the option to file jointly as well. If you have qualifying dependents, claiming them might increase your allowances and lower your taxes. However be cautious in claiming too many allowances as you don’t want to underpay in taxes all year and be slapped with a massive bill come tax season.
In December 2017, President Trump signed a new tax plan into law. The IRS has since released updated tax withholding guidelines and taxpayers should have seen changes to their paychecks, to reflect the new tax plan, starting in February 2018. For the time being, taxpayers do not need to fill out a new W-4. Employers will use the withholdings on your current form.
In addition to federal taxes, your employer will withhold 1.45% of your salary for Medicare taxes and 6.2% for Social Security taxes. Together these make up FICA taxes. If you earn in excess of $200,000, you will be charged a 0.9% Medicare surtax.
Another factor that affects the size of your paycheck is your pay frequency. If you are paid once a month, your paychecks will be bigger than if you get paid bi-weekly. If you only get paid once a month, you may also find it harder to budget correctly and not run out of money in between paychecks.

Known for its rolling plains and beautiful cornfields, Iowa is home to an income tax system that ranges from one of the lowest income tax rates in the country (0.36%) to one of the highest (8.98%).
The tax system is made up of nine tax brackets which are dependent upon residents' income level. The brackets remain the same for all taxpayers regardless of their marital or filing status. Iowans are taxed at 0.36% on the first $1,573 of their income; 0.72% up to $3,146; 2.43% up to $6,292; 4.5% up to $14,157; 6.12% up to $23,595; 6.48% up to $31,460; 6.8% up to $47,190; 7.92% up to $70,785 and 8.98% for income over $70,785.
Appanoose County has an additional 1% in local income tax.
Several Iowa school districts levy a surtax that is equal to a percentage of the Iowa taxes paid by residents. If you pay $2,000 in Iowa taxes and your school district surtax is 10%, you have to pay another $200. Check the chart below for the surtax rates for the 339 Iowa school districts that levy them.

How You Can Affect Your Iowa Paycheck
There are a number of ways that you can tweak your Iowa paycheck. It’s a good idea to review your W-4 form each year, particularly if you got a huge tax refund or you were surprised with a big tax bill back in April. Remember your W-4 form is the information that your employer uses to determine how much he or she should be withholding from each of your paychecks.
If you got a huge tax bill, you may be claiming too allowances and having too little in taxes taken out from each paycheck. If you think this is the case, you can claim fewer allowances on your W-4. On the other end of the spectrum, if you got a large tax refund, you may be overpaying your taxes throughout the year. Some people might like getting a big refund once a year as it forces them to save that money, but others may prefer to have access to the money throughout the year. Again, one option that may work for you is changing the number of allowances on your W-4.
You can also elect to have a dollar amount withheld from each your paychecks. In this case, you write down the total you want taken from each check, say $20, on your W-4. It may seem like you are choosing to receive a smaller paycheck each month, but think of it as paying more toward your taxes throughout the year, so you have a smaller bill (or maybe a smaller refund) come April.
Your paycheck size will also be affected by which company benefits you take advantage of. For example, if you get medical insurance for you and your spouse through your employer, those premiums will be paid out from your salary. Your employer may also offer pre-tax benefits like a Health Savings Account (HSA) or a Flexible Spending Account (FSA). If you know you have a few fixed health expenses, for example, you can put that money aside now, pre-tax, so not only will you have it when you need it, but it may help save you a few dollars in taxes by lowering your taxable income. One thing to note with HSAs and FSAs is that they do not roll over from year to year, so if you don’t use the money you put in them, you’ll lose it.
If you can afford it, putting more money into retirement accounts, such as a 401(k), 403(b) or Roth IRA is an excellent way to save for the future, particularly if your employer matches a certain percentage of your contribution.

Most Paycheck Friendly Places
SmartAsset's interactive map highlights the most paycheck friendly counties across the country. Zoom between states and the national map to see data points for each region, or look specifically at one of the four factors driving our analysis: Semi-Monthly Paycheck, Purchasing Power, Unemployment Rate, and Income Growth.
Methodology Our study aims to find the most paycheck friendly places in the country. These are places in the country with favorable economic conditions where you get to keep more of the money you make. To find these places we considered four different factors: semi-monthly paycheck, purchasing power, unemployment rate and income growth.
First, we calculated the semi-monthly paycheck for a single individual with two personal allowances. We applied relevant deductions and exemptions before calculating income tax withholding. To better compare withholding across counties we assumed a $50,000 annual income. We then indexed the paycheck amount for each county to reflect the counties with the lowest withholding burden.
We then created a purchasing power index for each county. This reflects the counties with the highest ratio of household income to cost of living. We also created an unemployment rate index that shows the counties with the lowest unemployment. For income growth, we calculated the annual growth in median income over five years for each county and indexed the results.
Finally, we calculated the weighted average of the indices to yield an overall paycheck friendliness score. We used a one half weighting for semi-monthly paycheck and a one-sixth weighting for purchasing power, unemployment rate and income growth. We indexed the final number so higher values reflect the most paycheck friendly places.
