Use Form 4506-T to request tax return information. Taxpayers using a tax year beginning in one calendar year and ending in the following year (fiscal tax year) must file Form 4506-T to request a return transcript.
There is a new transcript format that better protects taxpayer data. This new format partially masks personally identifiable information. Financial data will remain fully visible to allow for tax preparation, tax representation or income verification. Because the full SSN is masked, the IRS has created an entry for a Customer File Number. A 10-digit Customer File Number is selected by the requester and entered on a new Line 5b of Form 4506-T and 4506T-EZ. Learn more at About the New Tax Transcript and Customer File Number.
