Exemption

Employees hired before 2020 sometimes walk into HR carrying memories of their W-4 with "claimed 2 exemptions" written at the top. That W-4 no longer exists. The IRS redesigned the form to match the Tax Cuts and Jobs Act changes starting with 2020 forms, and personal exemptions went away entirely. Payroll and HR teams still get questions that use the old vocabulary, and the answers require translating between old concepts and the current system. Understanding what "exemption" used to mean, what replaced it, and how the current W-4 actually works keeps tax season conversations productive instead of confusing.

What Exemptions Used to Do

Before 2020, Form W-4 allowed employees to claim a number of allowances (often called exemptions) to reduce federal income tax withholding. The more allowances claimed, the less tax was withheld per paycheck. Employees with children, second jobs, or substantial itemized deductions typically claimed more allowances to more closely match their year-end tax liability.

The concept came from personal exemptions on the federal income tax return itself, which reduced taxable income by a fixed amount per taxpayer and dependent.

What Changed in 2020

The Tax Cuts and Jobs Act eliminated personal exemptions as a deduction on the 1040 starting with 2018 tax returns. The IRS then redesigned the W-4 for 2020 to remove allowances entirely. Today's W-4 asks employees to enter:

• Filing status
• Dollar amounts for dependents based on specific credit rules
• Other income or deductions if the employee wants them reflected in withholding
• An extra withholding dollar amount if desired

The result is a more direct calculation. Rather than translating allowance counts into withholding, the employer uses the actual income and credits the employee enters.

Do Employees Hired Before 2020 Need to Submit a New W-4?

No, unless they want to change their withholding. Employers continue to use the old W-4 on file until the employee submits a new one or has a change event. Employees who moved between employers or adjusted withholding since 2020 are on the new form by default.

Where "Exemption" Still Shows Up

One type of exemption survives on the current W-4: employees who meet specific IRS criteria can write "Exempt" in step 4(c) to indicate they expect no federal tax liability and want no federal income tax withheld. This requires meeting both conditions of the previous year having no tax liability and expecting the same in the current year. Exempt status has to be renewed annually.

State withholding exemptions work differently. Many state forms still use allowance-based exemptions even though federal does not. Payroll systems have to handle both.

Helping Employees Understand Exemption and Withholding Today

Send a simple W-4 explanation during new-hire onboarding and during open enrollment. Include examples showing how step 3 (dependent credits) and step 4 (other adjustments) translate to paycheck impact. A one-page summary prevents the bulk of mid-year adjustments that payroll teams handle one at a time.

Point employees to the IRS tax withholding estimator for personalized calculations. Tie communication to broader deduction explanations, before-tax deduction choices, and employee deductions on the paycheck. Review employee handbook payroll sections annually to keep language aligned with current IRS rules. Accurate withholding is what prevents the February surprise for both employee and employer.
