IRS Letter 916C: Meaning, Response Steps, and Refund Deadlines

IRS Letter 916C tells you the IRS has set your claim aside without processing it because something was missing — documentation, an explanation, a response to an earlier request, or a required verification step. It is not a bill, and it is not a formal denial of your refund. It means your amended return or refund claim is sitting in limbo until you fix the problem and resubmit, and the clock on your underlying refund rights keeps running while you do.

What “No Consideration” Actually Means

The full title of the letter is “Claim Incomplete for Processing; No Consideration.” The IRS employee handling your case assembles it from a library of pre-written paragraphs, and those selected paragraphs are the only reliable guide to what went wrong.¹ Read every paragraph. The reason listed determines what you do next.

“No consideration” is a specific status. The IRS has not decided your position is wrong. It has decided it will not evaluate your position in the form you submitted it. That distinction shapes everything else about how you respond.

Why the IRS Sends Letter 916C

The Internal Revenue Manual identifies several situations in which employees are directed to issue Letter 916C rather than process a claim:²

You didn’t respond to an earlier IRS request for additional documentation or clarification by the deadline given.
You didn’t reply within 45 days to an identity authentication letter such as Letter 4883C or Letter 5747C, so the IRS couldn’t confirm you actually filed the claim.
Your amended return or refund request didn’t include enough explanation or documentation for the IRS to evaluate it.
You submitted the same claim more than once and the IRS already addressed the first version.

In each case, the underlying tax position may be perfectly valid. The problem is procedural.

Letter 916C Is Not a Formal Disallowance

This is the part most people miss, and it matters more than any other detail in the letter. When the IRS formally denies a refund claim, it uses Letter 105C for a full disallowance or Letter 106C for a partial disallowance.³ Those letters start a two-year deadline to file a refund suit in federal court.⁴

Letter 916C does not. Because it’s a “no consideration” letter, it doesn’t trigger the two-year clock, and it doesn’t count as a final decision on your claim. You haven’t lost your day in court, but you also haven’t been given one yet. If you later receive a 105C or 106C after resubmitting, the two-year suit deadline runs from the mailing date of that later letter.⁴ Keep every piece of IRS correspondence, dated envelopes included.

What to Do After You Receive the Letter

Pin Down the Specific Problem

Read the selected paragraphs carefully. The IRS is required to tell you why the claim isn’t being considered.² If the letter says you failed to respond to an earlier request, check whether the request ever reached you. Mail goes missing, and the IRS sometimes writes to an old address. If the letter says your documentation was insufficient, work out exactly what was missing before you send anything else.

Build a Complete Package Before Resubmitting

Assemble everything that substantiates your claim: receipts, bank statements, W-2s, 1099s, or whatever supports the changes on your amended return. If identity was the issue, gather your government-issued ID and follow the verification steps in the authentication letter you received. Write a cover letter that explains what you’re claiming, why you’re entitled to it, and how each enclosed document supports your position. Reference the Letter 916C by date so the IRS can tie your new submission to the original case.

If your issue came out of an audit, the IRS accepts responses through its Document Upload Tool at irs.gov/examreply, or you can mail materials to the office that handled your case.⁵

Consider an Appeal

If you believe the IRS was wrong to reject the claim, you can ask the IRS Independent Office of Appeals to review it. For disputes of $25,000 or less, you can use a simplified process by filing Form 12203, Request for Appeals Review, following the instructions in your letter.⁶ For larger amounts, you’ll need a formal written protest that lays out your disagreement, the tax periods and amounts involved, and supporting documentation.

Watch Your Refund Statute of Limitations

Even though Letter 916C doesn’t start a suit deadline, the statute of limitations on your refund claim keeps running. You generally have three years from the date you filed your original return, or two years from the date you paid the tax, whichever is later.⁷ Miss that window and the IRS cannot legally issue a refund no matter how strong your position is.

The amount you can recover is also tied to timing. Filing within the three-year window limits your refund to tax paid during the three years before filing (plus any extension period). Filing outside the three-year window but inside the two-year payment window limits recovery to tax paid in the two years before filing.⁷

This is where Letter 916C quietly gets dangerous. If you wait months to resubmit a rejected claim, you can run past the statute without noticing. Check your deadlines the day the letter arrives. If expiration is close, file the corrected claim quickly even if your documentation isn’t perfect. An imperfect claim filed on time protects your rights better than a flawless claim filed too late.

Refund Claim or Abatement Request?

Some Letter 916C responses include a paragraph stating that while you can claim a refund of taxes already paid, the law does not allow you to file a claim to reduce a balance you still owe. The Taxpayer Advocate Service has criticized this language as misleading, because the IRS sometimes uses it when the real problem was simply incomplete paperwork.¹

The mechanics matter. If you’ve already paid the tax and want money back, that’s a refund claim, usually filed on Form 1040-X. If you haven’t paid and want the IRS to reduce what it says you owe, that’s an abatement request, and the IRS has more discretion to decline it. One workaround if your letter cites this reason: pay the assessed tax, then immediately file an amended return claiming a refund of that payment. That converts your position from an abatement request into a refund claim, which carries stronger procedural rights, including the eventual ability to file suit in federal court if the IRS denies it.

Letter 916C and the Employee Retention Credit

Since 2023, Letter 916C has shown up often in Employee Retention Credit cases. If you filed for an ERC, received Letter 105C or 106C disallowing it, and then sent additional information without specifically requesting an appeal, the IRS may issue a Letter 916C telling you the original disallowance stands.³ The IRS has also used Letter 916C to tell employers that a request to withdraw an ERC claim can’t be processed, for reasons that range from duplicate submissions to the claim having already been paid.⁸

The critical question in this situation is whether you previously received a Letter 105C or 106C. If you did, your two-year deadline to file a refund suit runs from the date on that earlier disallowance letter, not from the date of the later 916C.⁹ The 916C does not reset that clock. Find the original disallowance letter and confirm your deadline from its mailing date.

When the Taxpayer Advocate Service Can Help

The Taxpayer Advocate Service is an independent office within the IRS that helps taxpayers resolve problems they can’t fix through normal channels. TAS may be able to help if your Letter 916C situation involves a delay of more than 30 days in resolving a tax account problem, if the IRS failed to respond by a promised date, or if an IRS process didn’t work as intended.¹⁰ TAS can also step in when the delay is causing financial hardship or when you’ve been bounced between IRS departments without getting a straight answer.

TAS involvement makes the most sense after you’ve tried to resolve the issue yourself. Resubmit the claim with complete documentation, call the number on the letter, and if you still can’t get the IRS to act, reach TAS at 877-777-4778 or by filing Form 911, Request for Taxpayer Advocate Service Assistance. If your statute of limitations is about to expire and the IRS hasn’t processed your resubmitted claim, say so explicitly. A looming deadline is exactly the kind of urgency that moves a case up TAS’s priority list.
