Frequently Asked Questions

What is Form W-4?+
Form W-4 tells your employer how much federal income tax to withhold from your paycheck. Getting it right helps avoid large balances due or excessive withholding.
How do I avoid owing taxes?+
If you’re projected to under-withhold, you can increase extra withholding on Step 4(c) of your W-4. This calculator shows an estimated extra amount per paycheck.
Should I claim dependents on my W-4?+
If you have qualifying dependents, Step 3 can reduce withholding to reflect credits such as the Child Tax Credit ($2,000) and Other Dependent Credit ($500).
How often should I update my W-4?+
Update after major changes such as marriage/divorce, a new child, job changes, or changes in household income.
What if I have multiple jobs?+
Multiple jobs can cause under-withholding. Consider Step 2 adjustments and/or add extra withholding on Step 4(c).
