Tips for Adjusting Your W-4
Owe Every Year?
If you consistently owe at tax time, request additional withholding on Step 4(c) of your W-4. Add an extra dollar amount to be withheld from each paycheck. For the 2025 tax year, aim to have at least 90% of your total tax withheld to avoid underpayment penalties.
Large Refund Every Year?
A big refund means you're giving the IRS an interest-free loan. Adjust your W-4 to reduce withholding and keep more money in each paycheck. You can claim dependents or other credits on Step 3 of the W-4 to reduce withholding.
Life Changes?
Major life events — marriage, divorce, a new child, or a second job — require a new W-4. The IRS recommends reviewing your withholding whenever your personal or financial situation changes. Use the IRS Tax Withholding Estimator for a detailed check.
How the W-4 Form Works
The IRS Form W-4 tells your employer how much federal income tax to withhold from each paycheck. The current W-4 (redesigned in 2020) uses a simple 5-step process:
- Step 1: Enter your personal information and filing status (Single, Married Filing Jointly, or Head of Household).
- Step 2: Account for multiple jobs or a working spouse to ensure the correct amount is withheld across all jobs.
- Step 3: Claim dependents and other tax credits (Child Tax Credit, Credit for Other Dependents).
- Step 4: Make adjustments — other income (Step 4a), deductions (Step 4b), and extra withholding (Step 4c).
- Step 5: Sign and date the form.

W-4 FAQ
When should I update my W-4?
Update your W-4 whenever your tax situation changes: marriage, divorce, birth of a child, starting a second job, or a significant change in income. You can submit a new W-4 to your employer at any time — there's no need to wait for open enrollment.
What happens if I don't file a W-4?
If you don't provide a W-4 to your employer, they're required to withhold as if you're single with no adjustments — the highest withholding rate. This usually results in a larger refund (but smaller paychecks throughout the year).
How is the 2025 standard deduction reflected on the W-4?
The 2025 standard deduction ($15,000 single, $30,000 married filing jointly, $22,500 head of household) is built into the IRS withholding tables that employers use. You don't need to enter it separately — it's automatically factored in when your employer calculates withholding from your W-4.
