Do I have to fill out a W-4 every year?

In general, there are no obligations on your end as an employee to submit a new W-4 after the company files it. So you do not need to submit a new W-4 Form if you’re comfortable with your how many allowances you claim.

However, there are times where you need to submit a new Withholding Allowance Form. These situations include getting divorced or married, picking up a second or even third job, having a child or adopting a child.

Since all of these scenarios will change how many allowances you claim from the IRS point of view, submitting a new W-4 is the best way. Another way to determine if you should remain how many allowances you claimed throughout the year is to take a look at your tax return. If you withheld too much or less tax, you can submit a new W-4 so you don’t withhold too much tax or vice versa.


With that being said, the short answer to whether you need to file a new W-4 each year or not is no. If you like how much tax is being withheld from your paycheck, you can just keep it the way it is.

Keep in mind once you submit a new W-4 to your employer, it will take effect in the next three day period. Overall, you should monitor how much tax is being withheld from your paycheck.

Given that the IRS made it mandatory for every employee across the nation because it is required that you to pay your taxes gradually throughout the year, the W-4 Form is very important. So it should be treated as such or you might be facing underpayment penalties if you don’t withhold enough taxes.
