1. Lines 1–2: Name

   Enter the taxpayer name on line 1. For a sole proprietor or disregarded entity, use the owner’s name; put a different business name on line 2.

2. Lines 3–4: Classification

   Choose the federal tax classification. A disregarded LLC follows its owner’s classification; other LLCs enter C, S, or P as applicable. Follow instructions for line 3b and exemption codes.

3. Address and Part I

   Enter your address and the correct SSN or EIN under the instructions. The number must match the name on line 1.

4. Part II: Review and return

   Read the certifications and signature instructions. Sign and date when required, then give the form securely to the requester—not the IRS.

W-9 contains sensitive identity information. Verify the requester and use a secure delivery method. Ask us if you are unsure whose name or number to use.
