W-4 Form

✏️ Enter your 9-digit Social Security number exactly as it appears on your card.
Example format: 123-45-6789

Your employer uses this to report your income to the IRS and Social Security Administration. If it's wrong, your earnings might not be credited correctly.

✅ Tip: Double-check every digit — it's worth the extra few seconds. The dashes are optional; some forms include them, some don't.
