W-4 Calculator — FAQs
How do I change my withholding?
File a new W-4 with your employer. Step 3 = dependent credits ($2,000/child under 17); Step 4(c) = extra flat withholding per check.
Why withhold more than needed?
Safe harbour: owe under $1,000 at filing and no penalty. Big refunds mean over-withholding — tighten your W-4.
