The IRS encourages everyone to use the Withholding Calculator to do a Paycheck Checkup, which is even more important this year because of tax law changes. Taxpayers who haven’t yet done this can follow the steps below for using the calculator.
Results from the calculator will include a recommendation of whether they should consider submitting a new Form W-4, Employee’s Withholding Allowance Certificate, to their employers. Before beginning, taxpayers should have a copy of their most recent pay stub and tax return.
Use the buttons at the bottom of each page to navigate through the calculator. The buttons allow users to continue inputting their information, reset the information on that page, or start over from the beginning.
Input general tax situation information, including:
Input information about credits, including:
Enter the total estimated taxable income expected during the year. Amounts the user will enter include wages, bonuses, military retirement, taxable pensions, and unemployment compensation. Users should enter a “0” on lines asking for amounts that don’t apply to them.
Enter an estimate of adjustments to income, including deductible IRA contributions and education loan interest.
Indicate standard deduction or itemized deductions. Users who plan to itemize will enter estimates of these deductions.
Print out the summary of results. The calculator will provide a summary of the taxpayer’s information. Taxpayers use the results to determine if they need to complete a new Form W-4, which they submit to their employer.
