Determining how much money to have your employer withhold from your paychecks for federal taxes can be a bit tricky. If you withhold too little, you could be in for an unpleasant surprise when you file your next tax return. Not only could you owe a substantial amount of money, but you could potentially be slapped with an underpayment penalty as well. On the other hand, having too much money withheld from each paycheck could result in you overpaying your federal income tax. And paying too much in taxes is like letting the IRS borrow your money without receiving any interest for it. While it can be exciting to get a tax refund each year, it’s important to keep in mind that you’re only getting your own money back.
Achieve Balance with Federal Tax Withholding
Federal tax withholding can be a delicate balancing act. You should aim to have just enough withheld to cover your tax obligation, but it’s okay if your annual withholdings don’t exactly align with your tax bill. It’s alright if you have a bit too much withheld and end up receiving a small refund, or if your withholdings fall a little short and you owe a small amount when you file your tax return. The point is to get as close as you can to having the correct amount of taxes withheld so you can retain control of your money during the year, and avoid a large tax bill and unnecessary penalties when you file your taxes.
How Much Will I Owe?
A good place to start, when trying to determine the correct amount to withhold, is your last tax return. Did you receive a large refund, or owe a significant balance that was either hard to pay or subject to a penalty? If so, you probably need to adjust your withholding amount. The IRS has a digital Tax Withholding Estimator that you can use to help determine if you are currently having enough, or too much, withheld. If you find that your withholdings are insufficient or excessive, you can change your withholding amount by filling out a new W-4 form and returning it to your employer.
Updating Your W-4 Form
Prior to 2020, the W-4 form relied heavily on “withholding allowances” to determine how much to withhold from an employee’s paycheck for federal taxes. However, the W-4 form was updated in 2020 to better align with new tax laws, and allowances were removed completely. You can access the new W-4 form, as well as a list of frequently asked questions about it, at https://www.irs.gov/newsroom/faqs-on-the-2020-form-w-4. Accurately filling out the form should bring you very close to where you need to be from a withholding perspective.
The new W-4 form also includes an optional line for “extra withholding” where you can specify a dollar amount you want your employer to withhold, beyond what they would deduct based on the other information provided. This could be helpful if you are making changes to your W-4 mid-year and are afraid that your prior withholdings weren’t sufficient.
Review Your Withholdings Often
Remember that your W-4 form isn’t a “set it and forget it” thing. There are several factors that can impact your tax bill and could warrant changes to your withholding amount. Common situations that could affect how much tax you owe include:
Even if you’ve had the correct amount withheld from your paychecks in the past, changes like those mentioned above could warrant an update to your W-4 to ensure that your withholdings will still be adequate. And while using the IRS’ Tax Withholding Estimator and accurately filling out your W-4 form should get you close to where you need to be from a tax withholding perspective, it’s always wise to consult with a tax advisor before making changes to your withholding amounts.
