My 1099-R Is Wrong: The Two Different Fixes (2026)

Updated August 3, 2026. Quick answer: there are two different fixes and picking the right one matters. If the code is factually wrong — wrong amount, wrong account, a rollover reported as a distribution — ask the custodian for a corrected 1099-R. If the code is technically correct but uninformed — a code 1 where a real exception applies — you do not need the custodian at all. You claim the exception on Form 5329.

Box 7 is the payer’s claim, not the law

The code in Box 7 records what the custodian knew when it cut the cheque. It is not a ruling on what you owe, and the IRS instructions say so in as many words. On code 1 the instruction to payers is to use it “even if the distribution is made for medical expenses, health insurance premiums, qualified higher education expenses, a first-time home purchase…” and a list of other genuine statutory exceptions.

In other words the IRS expects the payer to report a distribution as unexcepted when the payer simply does not know, and expects you to claim the exception on your return. That is what Form 5329 is for, and it is the single most useful thing to understand about this form.

Which situation are you in?

• Claim it yourself on Form 5329 when the facts on the form are right but the code does not reflect an exception you qualify for. The IRS designed this path; the instructions to payers assume it.
• Ask for a corrected form when the form misstates a fact — the gross amount is wrong, it reports a distribution that was actually a direct rollover, the taxable amount is overstated, or it is not your distribution at all.

How to ask for a correction

• Contact the custodian in writing and state the specific box that is wrong and what it should say.
• Include documentation — the rollover confirmation, the transfer instruction, the statement showing the actual amount.
• Ask explicitly for a corrected Form 1099-R, not a letter. Only the corrected form changes what the IRS holds.
• Keep everything. If the deadline approaches without a correction, file accurately with an explanation rather than filing something you know to be wrong.

The cases people get wrong in both directions

• A code 1 with a real exception — not a form error. Form 5329.
• A code T on a Roth — not an error. The custodian could not verify your clock. Code T vs. Code Q on Form 1099-R.
• A code 7 covering a QCD — not an error either, because code Y is optional for 2026. You handle it on the return. Detail.
• A code 1 after breaking a 72(t) — correct, and the consequences are real. What breaking it costs.
