If calculating final pay sounds daunting, don’t worry. We designed a calculator that makes it easy to run an off-cycle paycheck for departing employees and meet your federal and state withholding tax requirements.
This gross-up calculator is designed to help you figure out how much you need to pay an employee if you want them to take home a specific amount of money after taxes are withheld.
Rewarding your employees for a job well done is a great way to say thank you, but the IRS calls bonuses “supplemental wages” and requires you to withhold taxes on them. The withholding calculation can be done two different ways: aggregate and flat (below). Aggregate withholding for bonuses might seem complicated, but we’ve designed an aggregate bonus calculator to help ease this payroll burden.
If you award bonuses to your employees as a separate payment and do not commingle them with regular wages, you can use the simpler flat bonus method to determine federal withholding taxes. Our flat bonus calculator can help you find the correct amount of federal and state taxes to withhold. Simply enter your employees’ gross bonus amount below and we’ll do the work.
If calculating withholding taxes on tips sounds complicated to you, don’t worry, we’ve designed a calculator specifically to tackle tip tax. Just enter your employees’ gross wages, their W-4 withholding information, and the tips they’ve earned into the calculator, and it will tell you what the resulting withholding tax and net pay should be.
As a small business owner, one of the best ways you can retain great employees is by offering a 401(k) retirement plan. However, there is some work involved in getting 401(k) deductions right, so we've designed a calculator specifically to help you figure out your employees’ take-home pay quickly and accurately. Just enter a few details about their plan, and the calculator will do the rest of the work for you.
Payroll Tax Calculators by State
In addition to federal taxes, employers must calculate and apply the appropriate state and local tax rates. The math works exactly the same, but the taxes levied by each state can vary dramatically. For example, seven states have no income tax at all. Others have state-specific equivalents of FICA and FUTA that employers will need to apply.
