CP111: What It Means and How to Respond

What the notice actually says

CP111 tells the business that the IRS "made changes to your return because we believe there's a miscalculation. As a result, you are due a refund." The instructions are minimal by design: nothing is required if the taxpayer agrees, a refund arrives within 4-6 weeks barring an offset against other debts, and the taxpayer can compare the notice's figures against the return or authorize a representative via Form 2848 if they want help (the IRS page Understanding your CP111 notice). (For where CP111 sits among the other IRS notices, see the IRS Notice Library.)

IRS Document 6209, Section 9 fixes the scope precisely: CP111 covers "Form 940 or 940EZ resulting in a net overpayment" — the identical Form 940 recomputation that produces CP101 when it nets the other direction. Same review, same form, opposite sign.

What actually triggered it

The IRS page says only that the IRS changed the return "because we believe there's a miscalculation" and that the change produced a refund. It does not say what the IRS corrected; call the number on the notice for specifics, and compare the corrected figures on the notice with your return. If you agree with the change, the IRS says to correct the copy of the return you kept for your records. If you want an accountant to contact the IRS for you, the IRS says to send Form 2848.

It's worth confirming the refund figure against the account transcript before assuming the correction is complete — a corrected 940 liability can interact with deposits already made for the same period, and the IRS Transcript Decoder shows exactly what posted against the period in question rather than relying on the notice's own bottom-line number alone.

Response deadline and what happens if you miss it

IRS.gov's CP111 page states none: neither its "What you need to do" instructions nor its FAQ gives a day count for disagreeing with the change. CP101's own page, by contrast, states a 10-day window. Check your own notice for any date it shows, because the IRS page does not give you one to rely on here.

The one time-sensitive fact CP111 does state is the refund timeline itself: "you should receive a refund of the overpaid amount within 4-6 weeks as long as you owe no other taxes or debts we are required to collect." If 6 weeks pass without the refund arriving, the notice's own FAQ says to call the number on the notice — that's a service-timing check.

What to do next

There's little to do proactively beyond confirming the refund posts within the stated 4-6 weeks and matching the corrected figure against the transcript, since IRS.gov's CP111 page says you do not need to do anything. If the refund is offset against another liability instead of arriving as a check, the account transcript will show the offset transaction — worth checking before assuming the refund simply hasn't processed yet.

If the client genuinely disagrees with the correction and would rather the IRS not send the refund at all — an unusual position, but the notice explicitly allows it — a phone call to the number listed is the stated mechanism to stop it, and IRS.gov names no date for that call. If ongoing correspondence is likely, filing Form 2848 up front saves a repeat authorization step later.

What people mistake CP111 for

CP111's direct mirror is CP101 — the identical Form 940 recomputation, per Document 6209's own table, just netting a balance due instead of a refund. The two are easy to conflate because they share the same underlying review and the same generic "we made changes" opening. The distinction that actually matters operationally: CP101 prints a 10-day deadline with real consequences for silence; CP111 prints none (the IRS page Understanding your CP101 notice). A business that received both notices in different years, or heard about the 10-day rule from a CP101 conversation, might wrongly assume the same clock applies here (the IRS page Understanding your CP101 notice). It doesn't.

CP111 is also worth separating from the individual refund-side math-error notice this site already covers, CP12. Both are "you're getting money back" letters, but they arise under entirely different authority — CP12 under IRC §6213(b)(1), CP111 outside it entirely, because employment taxes were never subject to deficiency procedures (IRC §6211(a)). CP12 carries a 60-day deadline to ask the IRS to reverse the change (IRC §6213(b)(2)(A)); the IRS page for CP111 states no deadline, and only CP12's family carries the formal §6213(b)(2) abatement right.

CP111 is also worth distinguishing from CP112, which looks nearly identical on the page but corrects a different return entirely — Form 941, 943, 944 or 945 rather than Form 940.
