How to Fill Form 4506 (2026): Request a Copy of Your Tax Return

Form 4506 requests an exact photocopy of a tax return you already filed — the full document, not a summary. It carries a fee per return and can take a couple of months. Most people who reach for it actually need the free, faster transcript instead. Use Form 4506 only when something specifically requires a true copy of the return as filed.

What Form 4506 Is

Form 4506, "Request for Copy of Tax Return," asks the IRS to send a complete photocopy of a return you previously filed, including the forms and schedules attached to it. Because it's the real document rather than an extract, it costs a fee and takes longer to arrive than the alternatives.

Form 4506 vs 4506-T: Copy or Transcript?

These two are constantly confused because the numbers are almost identical. The difference decides which one you should actually file:

CostA fee per returnFree
TurnaroundUp to ~75 daysDays to a couple of weeks
Use it whenYou need the actual return as filedA lender, school, or agency just needs income data

If a mortgage lender, financial-aid office, or immigration sponsor asks for your "tax return," they almost always accept — and often prefer — a transcript. In that case, the free Form 4506-T is the right form, and Form 4506 is an unnecessary fee and wait.

How to Fill Form 4506

  1. Lines 1–4 — Your identity. Name and SSN (or EIN) exactly as they appeared on the return you're requesting, plus current and prior address.
  2. Line 5 — Third-party recipient. If the copy should go directly to someone else (a lender, an attorney), enter their name and address; otherwise it comes to you.
  3. Lines 6–7 — Form and years. The tax form number (e.g. 1040) and each year or period you want, in the format the form specifies.
  4. Fee and signature. Include the required fee per return and sign. The signature has a limited validity window, so don't sign it far ahead of mailing.

How much does Form 4506 cost?

The IRS charges a fee for each return copy requested — check the current amount on irs.gov, as it's set by the IRS and can change. There's no charge at all for a transcript on Form 4506-T, which is why the transcript is the default choice unless you specifically need the full copy.

When do I actually need a full copy instead of a transcript?

When something requires the return exactly as filed — for example, certain legal proceedings, an amended-return dispute, or a request that explicitly says "a copy of the return, not a transcript." For everyday income verification, the transcript is enough and saves both the fee and the wait.
