Each year, the IRS releases an updated W-4 form, and while it's not mandatory for employees to fill out a new one annually, it’s a smart move to review it. Adjusting withholding helps employees avoid surprises like a big tax bill or an oversized refund at tax time.
For household employers, understanding the W-4 is equally important. New hires must complete one, and it’s wise to encourage current employees to review theirs. This guide will walk you through the key steps, updates for 2025, and why the W-4 matters for both employers and employees.
The W-4, officially called the "Employee’s Withholding Certificate," tells employers how much federal income tax to withhold from an employee’s paychecks. Accurate withholding ensures employees aren’t hit with unexpected taxes later.
Since 2020, the W-4 has no longer used “allowances” (thanks to the Tax Cuts and Jobs Act). Instead, it focuses on simple, clear instructions to better match withholding to an employee’s financial situation.

While the overall structure remains the same, key figures like the standard deduction have changed:
These adjustments impact who might benefit from itemizing deductions (Step 4b).
Skipping the Form Entirely
Employers are legally required to have new hires fill out this form. Also, if a new employee doesn’t complete a W-4, you (the employer) must withhold taxes as if they’re Single with no adjustments. This could result in higher-than-necessary withholding.
Claiming "Exempt" Without Qualification
While it may be tempting for employees to mark themselves as "exempt," doing so incorrectly can lead to big tax liabilities. Only employees with zero tax liability last year and expected zero this year should claim exempt. For most household workers, this won’t apply.
Ignoring Step 2 (Multiple Jobs)
If an employee (or their spouse) works multiple jobs, not accounting for it can lead to under-withholding — and a big tax bill later.
