Frequently Asked Questions
How do I adjust my federal withholding?
Submit a new Form W-4 to your employer. To increase withholding (reduce refund), enter extra withholding on Line 4(c). To decrease withholding (increase take-home pay), claim dependents on Step 3 or deductions on Line 4(b).
Is getting a large tax refund good?
Not necessarily. A large refund means you overpaid throughout the year, giving the government an interest-free loan. Ideally, you should aim to break even or get a small refund. The money is better in your paycheck where you can invest it.
When should I update my W-4?
Update your W-4 after major life changes: marriage, divorce, having a child, buying a home, starting a side job, or receiving a significant raise. Also review annually to ensure withholding matches your expected tax liability.
