At a Glance
Filed a 1099 with the wrong TIN, incorrect amount, or wrong payee name? You need to file a correction through IRIS. IRIS uses Type 1 corrections (for payee name or TIN errors) and Type 2 corrections (for amount or code errors), plus void submissions to cancel returns entirely. BoomTax handles all correction types automatically — just update the record and BoomTax files the correction with the IRS.

Understanding Correction Types
The IRS classifies information return corrections into two categories, each with different procedures. Getting the correction type wrong can result in duplicate records on the IRS side, creating more problems than the original error. Here's how each type works:
Type 1 Corrections: Payee Name or TIN
Use a Type 1 correction when you need to fix the payee's name, Taxpayer Identification Number (TIN), or both. Type 1 corrections are also called "two-transaction" corrections because they require two steps:
- Zero out the original: Submit a corrected return with the original (incorrect) payee name and TIN, but with all amount fields set to zero. This effectively nullifies the original filing.
- File the correct data: Submit a new return with the correct payee name and/or TIN, along with the correct amounts.
This two-step process is necessary because the IRS matches returns by TIN. If you simply submitted a corrected return with the new TIN, the IRS would treat it as a new filing rather than a correction of the original.
Type 2 Corrections: Amounts or Codes
Use a Type 2 correction when the payee name and TIN are correct but an amount, checkbox, or code is wrong. Type 2 corrections are simpler — they are a single-transaction correction:
- Submit the corrected return with the same payee name and TIN, marked as a corrected return, with the correct amounts in all boxes (not just the changed boxes — include all amounts, even those that were already correct).
The corrected return replaces the original in the IRS system. This is why you must include all amounts, not just the one you're changing.
How Corrections Worked in FIRE vs. IRIS
Under the FIRE system, corrections were filed using the same Publication 1220 flat-file format as original returns, with specific indicator codes in designated character positions. The fixed-width format made corrections especially error-prone — a single misaligned character in the correction indicator field could cause the IRS to process a correction as a new original filing.
Under IRIS, corrections use clearly labeled XML elements:
- CorrectedInd: A boolean element marking the return as a correction
- CorrectedReturnTypeCd: Specifies whether this is a Type 1 or Type 2 correction
- VoidInd: Marks a return as voided rather than corrected
The structured XML format eliminates the character-position errors that plagued FIRE corrections. Schema validation catches missing or malformed correction indicators before submission, preventing silent processing failures.
Void vs. Corrected Returns
A void is different from a correction. Use a void when:
- The original return should never have been filed (e.g., you filed a 1099 for someone who was actually a W-2 employee)
- You need to completely cancel a previously filed return with no replacement
- A return was filed in error for someone you had no reporting obligation to
To void a return through IRIS, submit the original return data with the VoidInd element set to true. All amount fields should match the original filing. The IRS will remove the return from the payee's tax record.
Do not void a return when you intend to refile it with different data — that's a correction, not a void.
Correction Timing and Deadlines
There is no hard IRS deadline for filing corrections — you can file a corrected return at any time after the original was accepted. However, best practices include:
- File as soon as you discover the error. The longer you wait, the more likely the payee will file their own return based on incorrect information, creating a mismatch that triggers IRS notices.
- Before the filing deadline if possible. If you catch an error before the original filing deadline, filing the correction immediately avoids any potential penalty exposure.
- Issue corrected recipient copies. Whenever you correct a return with the IRS, you must also provide a corrected copy to the payee (Copy B marked "CORRECTED").

Common Correction Scenarios
Wrong TIN
The most common correction. You reported the correct amounts but used the wrong SSN or EIN for the payee. This is a Type 1 correction: zero out the original with the wrong TIN, then refile with the correct TIN and correct amounts.
Wrong Amount
You reported $50,000 in Box 1 of a 1099-NEC but the correct amount is $45,000. This is a Type 2 correction: submit a corrected return with the same payee information and the correct amount in all boxes.
Wrong Form Type
You filed a 1099-MISC when you should have filed a 1099-NEC. This requires two actions: void the incorrect 1099-MISC, then file a new original 1099-NEC. This is not technically a "correction" — it's a void plus a new filing.
Multiple Corrections on the Same Form
If you need to correct a return that you've already corrected once, file another correction referencing the most recently accepted return. IRIS tracks the correction chain, so each new correction supersedes the previous one. Avoid filing multiple corrections in rapid succession — wait for the IRS acknowledgment on each correction before filing the next.
How BoomTax Handles Corrections Automatically
BoomTax eliminates the complexity of the correction process:
- Automatic type detection: BoomTax determines whether your change requires a Type 1 or Type 2 correction and generates the appropriate XML
- No manual XML: Just update the record in BoomTax. The platform builds the correction submission, including the zero-out step for Type 1 corrections
- Void support: Mark a return as void in BoomTax and it handles the void submission through IRIS
- Corrected recipient copies: BoomTax generates and delivers corrected Copy B to the payee
- FIRE-format compatibility: If your original was filed via FIRE-format files uploaded to BoomTax, corrections are still handled through IRIS — no format change needed on your end
Frequently Asked Questions
Through the IRIS Taxpayer Portal, select the original return and choose the correction option. For a Type 2 correction (wrong amounts), enter the correct data and submit. For a Type 1 correction (wrong name/TIN), you must first zero out the original return, then file a new return with correct information. With BoomTax, simply update the record — the platform handles the correction mechanics automatically.
Type 1 corrections fix the payee name or TIN and require a two-step process (zero out the original, then file with correct information). Type 2 corrections fix amounts, codes, or checkboxes and require only a single corrected return submission. Using the wrong correction type can create duplicate records in the IRS system.
Yes. To void a return, submit the original return data through IRIS with the void indicator set. This removes the return from the payee's IRS tax record. Use a void when the return should never have been filed at all — not when you need to change amounts or payee data (that's a correction).
There is no hard IRS deadline for filing corrections. You can correct a previously filed return at any time. However, filing corrections promptly is strongly recommended — delays increase the chance of IRS notices and payee confusion. If you correct before the original filing deadline, there is generally no penalty exposure. Corrections filed after the deadline may be subject to penalties depending on the circumstances.
Yes. After the FIRE system shuts down on December 31, 2026, all corrections — including those for returns originally filed through FIRE — must be submitted through IRIS. The IRS maintains records across both systems. If you use BoomTax, your correction is processed through IRIS regardless of how the original was filed.
