The IRS encourages everyone to use the Tax Withholding Estimator to perform a quick “paycheck checkup.” This is even more important following the recent changes to the tax law for 2018 and beyond.
The Tax Withholding Estimator helps you identify your tax withholding to make sure you have the right amount of tax withheld from your paycheck at work.
If you are an employee, the Tax Withholding Estimator helps you determine whether you need to give your employer a new Form W-4, Employee’s Withholding Allowance Certificate (PDF). You can use your results to help fill out the form and adjust your income tax withholding. If you receive pension income, you can use the results from the estimator to complete a Form W-4P (PDF) and give it to your payer.
The Tax Withholding Estimator will ask you to estimate values of your 2019 income, the number of children you will claim for the Child Tax Credit and Earned Income Tax Credit, and other items that will affect your 2019 taxes. This process will take a few minutes.
IMPORTANT NOTE: This Tax Withholding Estimator works for most taxpayers. People with more complex tax situations should use the instructions in Publication 505, Tax Withholding and Estimated Tax (PDF). This includes taxpayers who owe alternative minimum tax or certain other taxes, and people with long-term capital gains or qualified dividends.
Special Note for 2020: If you follow the recommendations at the end of the Tax Withholding Estimator and change your withholding for 2019, the IRS reminds you to be sure to recheck your withholding at the start of 2020. This is especially important if you reduce your withholding sometime during 2019. A mid-year withholding change in 2019 may have a different full-year impact in 2020. So if you do not file a new Form W-4 for 2020, your withholding might be higher or lower than you intend. To help protect against having too little withheld in 2020, we encourage checking your withholding again early in 2020.
