How do I fill out a W-4?

A Form W-4 tells your employer how much federal tax to withhold from your paychecks. The current form asks about your filing status, multiple jobs or a working spouse, dependents, and any extra withholding you want. If you had a large refund or a large balance due last year, adjusting your W-4 can help you get closer to breaking even. The IRS offers an online Tax Withholding Estimator to guide your entries. Review your W-4 after major life changes like marriage, a new job, or a baby. For complex situations, a professional can help.
