DRAFT 2026 IRS FORM W9 – Do Not Use

The IRS has issued a draft version of an updated Form W9 ‘Request for Taxpayer Identification Number and Certification’ dated as ‘Rev. June 2026’. Individuals searching online may find the draft version, which is clearly marked “TREASURY/IRS AND OMB USE ONLY DRAFT” and “DRAFT — DO NOT FILE”. This form will not be accepted for supplier setup purposes until such time as it is finalized by the IRS. An update will be sent when the new form is finalized and will be accepted (and will include dates at which CTS will stop accepting any previous form versions). The only currently accepted form W9 is the version dated ‘Rev March 2024‘.

Thank you.
