This bonus tax aggregate calculator uses your last paycheck amount to apply the correct withholding rates to special wage payments, such as bonuses. This is state-by state compliant for those states that allow the aggregate method or percent method of bonus calculations. See payroll calculation FAQs below.

What was updated in the Federal W4 in 2020?
In 2020, the IRS updated the Federal W4 form that eliminated withholding allowances. The redesigned Form W4 makes it easier for your withholding to match your tax liability. Here’s how to answer the new questions:
- Step 2: check the box if you have more than one job or you and your spouse both have jobs. This will increase withholding.
- Step 3: enter an amount for dependents.The old W4 used to ask for the number of dependents. The new W4 asks for a dollar amount. Here’s how to calculate it: If your total income will be $200k or less ($400k if married) multiply the number of children under 17 by $2,000 and other dependents by $500. Add up the total.
- Step 4a: extra income from outside of your job, such as dividends or interest, that usually don't have withholding taken out of them. By entering it here you will withhold for this extra income so you don't owe tax later when filing your tax return.
- Step 4b: any additional withholding you want taken out. Any other estimated tax to withhold can be entered here. The more is withheld, the bigger your refund may be and you’ll avoid owing penalties.
If your W4 on file is in the old format (2019 or older), toggle "Use new Form W-4" to change the questions back to the previous form. Employees are currently not required to update it. However if you do need to update it for any reason, you must now use the new Form W-4.
What’s the difference between a deduction and withholding?
In addition to withholding federal and state taxes, part of your gross income might also have to contribute to deductions. These are known as “pre-tax deductions” and include contributions to retirement accounts and some health care costs. For example, when you look at your paycheck you might see an amount deducted for your company’s health insurance plan and for your 401k plan. Pre-tax deductions result in lower take-home, but also means less of your income is subject to tax. Some deductions are “post-tax”, like Roth 401(k), and are deducted after being taxed.
In our calculators, you can add deductions under “Voluntary Deductions” and select if it’s a fixed amount (pre-tax), a percentage of the gross-pay (pre-tax), or a percentage of the net pay (post-tax). For hourly calculators, you can also select a fixed amount per hour (pre-tax).
