What is Form D4?

Common Mistakes to Avoid

• Leaving fields blank: Every required box must be completed; otherwise your employer may withhold tax at the maximum rate.
• Incorrect Social Security Number: Double‑check the nine‑digit number to avoid processing delays.
• Using the wrong filing year: The top of the form indicates the tax year—make sure it matches the current year.
• Signing with a printed name only: Use a digital signature or type your name in the signature field; a handwritten signature is not needed when using Formize.

Where to Submit Your Completed D4

After you save the completed PDF, send it to your employer’s payroll department via email or upload it to the company’s secure portal. Keep a copy for your records in case the employer requests it later.
