Requesting a W-9
This makes a cover letter to request a vendor's completed W-9. It does not determine whether a W-9 or a tax filing is required.
Example: you are adding a supplier to your records. Enter the supplier, your contact details, a response date and return instructions, then print the letter.
Use the official IRS Form W-9 and its instructions. The response date is yours to choose, not an IRS deadline. Check the recipient and return instructions before sending.
