Frequently asked questions

One of the biggest changes on the redesigned W-4 form is the elimination of personal withholding allowances. Instead, the form uses a 5-step process and new Federal Income Tax Withholding Methods to determine actual withholdings. In the past, the value of withholding allowances was also tied to personal and dependent exemptions, but those exemptions were eliminated under The Tax Cuts and Jobs Act signed
in 2017.

IRS Form W-4 is completed and submitted to your employer, so they know how much tax to withhold from your pay. Your W-4 can either increase or decrease your take home pay. If you want a bigger refund or smaller balance due at tax time, you’ll have more money withheld and see less take home pay in your paycheck. If you want a bigger paycheck, you’ll have less withheld and have a smaller refund or larger balance due at tax time.

  • Use the W-4 calculator to adjust your withholdings and determine how to fill out your W-4.
  • Once you’re ready to update your W-4, reach out to your employer or download and print a blank
    W-4 form
  • Submit it to your employer as soon as possible. It could take up to a few weeks for adjustments to be reflected
    on your paycheck.

When you use the redesigned Form W-4, your withholding is based on your expected filing status and standard deduction for the year. The new redesigned Form W-4 makes it easier for you to figure out your withholding, especially if you have income from multiple jobs, itemized deductions, the child tax credit, and other tax benefits.

The W-4 calculator can help you adjust your withholdings to determine if you’ll get a refund or a balance due come tax time. Once you’re happy with your projected outcome, the W-4 calculator will show how to fill out your W-4. Depending on your employer, updates to your W-4 could take a few weeks to be reflected on
your paycheck.

It’s important to remember that getting a tax refund means you paid too much federal income to the IRS during the year, so you are owed money. If you are seeking a bigger refund come tax time, the simplest way is to update your W-4 to have more money withheld from your paycheck. The W-4 withholding calculator can help you determine how to adjust your withholdings. The less your take-home pay, the bigger your refund will be. However, it’s possible to maximize your paycheck amount and still get a tax refund. Learn how

The federal tax withholding calculator, or W-4 calculator, helps you determine how much federal income tax should be withheld from your pay. It considers your filing status, income, dependents, and more to estimate your yearly tax and suggest W-4 allowances. Adjusting these allowances can influence your paycheck's tax withholding to closely match your actual tax liability. Remember, the federal withholding calculator is a helpful tool, but it's an estimate. Learn more about W-4s.

It's a good idea to check your W-4 withholdings anytime there's a major change in your life that could impact your taxes, like marriage, a new child, buying a home, or a big change in income. When you change employers, you will fill out a new W4, and that is a great time to make sure you are filling it in correctly. At a minimum, it's wise to review your withholdings annually. See the top 5 reasons to adjust your W-4 withholding.

Using a tax withholding estimator like the TurboTax calculator or a W-4 calculator has many benefits. It helps manage your tax withholdings to avoid paying too much or too little, preventing unexpected tax bills or underpayment penalties. It also lets you adjust your withholdings to optimize your paycheck and plan for life changes that might affect your taxes. For future planning, consider using the tax refund calculator tax filing season to estimate your upcoming tax situation.

To complete the W-4 calculator, you'll need a few key pieces of information:

  • Your most recent paystub: This will help you enter your taxable income per pay period.
  • Total of wages received so far: This is important for calculating your annual income.
  • How much is withheld from your paycheck for federal and state taxes: You can find this information on your paystub.
  • Estimates for deductions and expenses: If you plan to itemize deductions, having these handy will help you estimate your potential tax savings.

Having these items ready will make the process smoother and the results more accurate.
