W-9 | How to Find your TIN • Taxpayers can see their tax identification number (TIN) on their IRS tax forms or on the back of their check. • If you do not have a W-9, we recommend that you provide your valid Social Security Number and your date of birth, so others can easily obtain this information. • When sending your information to the IRS, include your TIN in the message box. Keep a copy of the W-9 you send to the IRS, including the W-9 Number. • To receive a W-9, please submit all correct filing-related information as of the filing-due date. For example, if you are filing this tax year for the first time, complete the W-9 form, attach it and send to the IRS the information indicated to you on the form.
