Frequently Asked Questions
What is a W-4?
The W-4 is the form you give your employer to determine how much federal income tax to withhold from each paycheck. Getting it right means you won't owe a big bill at tax time or give the IRS an interest-free loan via a large refund.
Should I claim 0 or 1?
The current W-4 (redesigned in 2020) no longer uses allowance numbers. Instead, you enter dollar amounts for dependents, other income, deductions, and extra withholding. This calculator tells you exactly what to enter in each field.
When should I update my W-4?
Update it after any major life change: new job, marriage/divorce, having a child, buying a home, or if your last refund or balance due was larger than you expected.
