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 to withhold in taxes from each of your paychecks. Regardless of your pay frequency, 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.
Multiple factors affect your withholdings. Your marital and filing status is a big part of it. Whether you’re single or married; whether you’re filing jointly or separately; and whether you file as the head of the household, will all 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, this may also affect your bill come tax season.
It’s worth mentioning that because of the new tax plan signed by President Trump in December 2017, withholding rates changed a bit from 2017 to 2018. If you haven’t checked yet, it’s a good idea to make sure the information in your W-4 is still correct. While there weren't really any changes to the withholding form in 2019, the 2020 version comes with major updates.
Instead of using allowances, the 2020 W-4 features a five-step process that requires filers to use annual dollar amounts to indicate any additional income. The IRS requires all employees hired as of Jan. 1, 2020 to complete the form. If you were hired before then, you'll only need to complete the form if you plan on changing jobs or adjusting your withholdings in 2020.
In addition to federal income taxes, your employer withholds 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. Note that the FICA taxes are actually double the rate that you pay because your employer contributes an equal amount. If you are self-employed, you will have to pay the full rate of 2.9% for Medicare and 6.2% for Social Security. The good news is that when you file your taxes, there are some deductions you can take to recoup the “employer” portion.
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.

How You Can Affect Your Iowa Paycheck
There are a number of ways that you can tweak your Iowa paycheck. First of all, it’s a good idea to review your W-4 form each year. Since your W-4 form is the information that your employer uses to determine how much to withhold, you want to make sure the information is correct.
If you got a large tax refund, you may be overpaying on 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 it’s also nice to have that money in your bank account throughout the year.
Your paycheck size will change if you take advantage of any company benefits. 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. Money you put in these accounts comes out of your pay before income tax and thus it lowers how much of your salary is subject to income tax. Examples include 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 into one of these accounts so that you have it when you need it and save on taxes along the way. One thing to note with FSAs is that only $500 will roll over from year to year, so if you don’t use the money you put in, you may lose it.
Other pre-tax contributions worth considering are for retirement accounts, such as a 401(k) or 403(b). You should especially consider one of these accounts if your employer offers a matching program.

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.
