How to Fax IRS Form 4506-T Online (Tax Transcript Request) | SecurelyFax
Form 4506-T is the Request for Transcript of Tax Return — the form you submit to the IRS when you need a transcript of a prior-year return and the online Get Transcript path isn't an option for you. The IRS lists fax as an accepted submission method in the form's current instructions, with destination numbers that depend on where you live. SecurelyFax sends the signed Form 4506-T from email, browser upload, or a phone scan and returns a delivery confirmation.
What Form 4506-T does
Form 4506-T orders a transcript of your tax return — a summary the IRS produces from its own records — and delivers it to a third party you name (a mortgage underwriter, a small-business lender, a student-loan servicer, a CPA). Transcripts are different from tax-return copies: they show line-by-line data, but they are typically free and arrive faster than full return copies.
When fax is the right path for 4506-T
The IRS now points many taxpayers to Get Transcript Online or Get Transcript by Mail for personal use, and either of those is faster than mailing or faxing the paper form. Fax is the path when those options don't apply — for example, when a third party is requesting the transcript on your behalf or when the online tools cannot verify your identity. Always check the current instructions for which channel applies to your situation.

Common uses for a 4506-T fax
Mortgage underwriting and conventional loan processing are by far the most common: the lender pulls transcripts to verify income on the application. Small-business lending, financial-aid verification, and tax-resolution casework round out the list. In every case the third party is waiting on the transcript, so the speed of getting the authorization onto the IRS record matters.
SecurelyFax is not affiliated with the IRS and cannot file Form 4506-T on your behalf. It transmits the completed, signed form to the destination number you provide and returns a delivery confirmation. The IRS instructions are the source of truth for which method and number to use.
Frequently asked questions
Should I use 4506-T or Get Transcript Online?
