IRS Notice CP 287C
What IRS Notice CP 287C means
IRS Notice CP 287C is a notice tied to the account issue described in CP 287C. That sounds dry, but the practical point is simple: the IRS has a question, a proposed change, a balance, a refund issue, or a missing piece in its file. The notice number matters because the IRS uses that number to describe the type of problem it believes exists.
A taxpayer should not treat IRS Notice CP 287C like generic junk mail. The IRS says most notices deal with a specific issue and usually explain what action, if any, the taxpayer should take. The problem is that IRS letters are written for the IRS first and the reader second. They can be technically correct and still hard to follow. One paragraph might refer to a tax year. Another might mention a refund, balance, credit, penalty, or deadline. The job is to slow down and read the notice like evidence, not like a threat.
Most account notices are not dramatic, but they still need attention. IRS Notice CP 287C is tied to a tax year, a return, a payment, a penalty, a credit, or another account entry. The notice is the IRS version of a paper trail. Read it against the return and the transcript before deciding what it means.
Why you received IRS Notice CP 287C
You received IRS Notice CP 287C because the IRS believes something connected to the account issue described in CP 287C needs attention. The trigger could be a tax return entry, a payment posting, a missing form, a third-party income document, a refund adjustment, a credit review, a penalty, or an account mismatch. Sometimes the IRS changed the return during processing. Sometimes it compared the return to W-2s, 1099s, K-1s, brokerage records, payroll filings, or other data sent by someone else.
Do not assume the IRS is right. Do not assume it is wrong either. That is the boring answer, but it is the answer that saves people money. The notice has to be checked against the filed return, the taxpayer’s records, and the IRS transcript for the year involved.
A common example: a taxpayer moved, changed banks, made an estimated payment under the wrong Social Security number, or received a late Form 1099 after the return was filed. The IRS computer sees a mismatch and sends a notice. Another common version is even more ordinary. The taxpayer entered a number on the wrong line, forgot a schedule, or claimed a credit without attaching the support the IRS wanted to see.
Why IRS Notice CP 287C matters
IRS Notice CP 287C matters because the notice can affect money and future IRS contact. A small refund adjustment can turn into a bigger problem if the taxpayer ignores the explanation. A balance notice can pick up penalties and interest. A proposed adjustment can become harder to dispute if the taxpayer misses the response date. A collection notice can move the account closer to levy activity.
The most dangerous IRS notice is not always the one with the biggest number. It is the one the taxpayer misunderstands. Someone might pay a balance that should have been disputed. Someone else might ignore a correct notice because the IRS wording annoyed them. Neither approach is smart. The better move is to identify what the IRS changed, what records support or contradict the change, and what response path the notice allows.
For IRS Notice CP 287C, the taxpayer should look for the notice date, response deadline, tax year, form number, amount due or refund change, and contact instructions. If the notice includes a payment voucher, that does not automatically mean payment is the only option. If the notice says no response is needed, the taxpayer should still keep it with the return records. IRS notices have a way of becoming relevant months later.
Start with the account record
For IRS Notice CP 287C, the account transcript is often the best place to start because it shows what the IRS has actually posted. The notice gives the IRS explanation. The transcript shows the account activity. The return shows what the taxpayer reported. Those three records should tell one story. When they don’t, that gap is where the work begins.
How some people handle IRS Notice CP 287C
Some people handle IRS Notice CP 287C by creating a simple file before they do anything else. They keep the full notice, the envelope if timing matters, the filed return, wage and income forms, proof of payments, refund records, and any prior IRS letters for that tax year. Then they mark the deadline on a calendar. Not exciting. Very useful.
After that, they compare the IRS version of the facts to their own records. If the notice involves income, they check each W-2, 1099, brokerage statement, K-1, retirement form, and business income record. If it involves a payment, they look for bank withdrawals, Direct Pay confirmations, EFTPS receipts, canceled checks, payroll tax deposits, or estimated tax vouchers. If it involves a credit or dependent, they gather the records that prove eligibility rather than sending a vague explanation.
Some taxpayers agree with IRS Notice CP 287C after doing that review. Some partly agree and partly dispute it. Others respond because the IRS used incomplete information or posted something incorrectly. The right response depends on the notice language, the account transcript, the tax year, and the proof available. A short, clear response with the right documents is usually better than a long letter that explains everything except the actual issue.
Original documents should usually stay with the taxpayer unless the IRS specifically asks for them. Copies, labeled pages, and a mailing record are safer. If the notice allows faxing or online upload, the taxpayer should still save proof of what was sent and when.
How The Reed Corporation can help
The Reed Corporation can review IRS Notice CP 287C and translate it into plain English: what the IRS says, what year is involved, what deadline matters, and what records should be checked before anyone responds. A lot of notice work starts with that step. The letter feels less scary once the issue is named.
We can compare the notice to the filed return, review transcripts, check payment history, look for missing income forms, review credit eligibility, and organize a response package when the facts support one. For balance notices, we can help look at payment options and account status. For refund notices, we can help trace what changed. For examination or proposed adjustment notices, we can help pull the records into a cleaner response.
The point is not to argue with every IRS notice. The point is to avoid guessing. If IRS Notice CP 287C is correct, the taxpayer needs a practical plan. If it is wrong, the response should be specific enough for the IRS to fix the account. If it is partly right, the taxpayer may need to separate the agreed items from the disputed ones.

Frequently Asked Questions
What does an IRS CP 287C notice actually mean?
A CP 287C notice means the IRS denied your Form 8716 because your entity already made an IRC Section 444 election in a prior year and that election was terminated. The CP 287C is a denial, not a bill. The IRS is telling you flatly that you cannot make a second Section 444 election, because the law allows that election exactly once per entity for its entire life. So when your partnership, S corporation, or personal service corporation tried to elect a tax year other than its required tax year a second time, the system kicked it back with a CP 287C. The plain reading you should take from a CP 287C: keep filing on your required tax year, which is almost always the calendar year ending December 31. You can read the IRS explanation of this exact notice at Understanding your CP287C notice.
Here is the mechanics behind a CP 287C. Section 444 lets a flow-through entity keep a fiscal year that differs from the required year, but only if it makes a one-time election on Form 8716 and keeps a required payment current under Section 7519. Once that Section 444 election ends, whether because you switched back to a calendar year, the entity stopped paying the required deposit, or the entity was penalized under Section 280H, the door closes for good. A CP 287C is the IRS confirming that door is shut. The form you tried to file is described at About Form 8716. The CP 287C is part of the same CP 287 family of fiscal-year notices, and the C suffix is the version that signals a denied or terminated election rather than a routine reminder.
Why does the tax code limit you to one Section 444 election. The deferral a fiscal year buys is a timing benefit, and Congress did not want pass-through entities flipping their year-end back and forth to chase the best deferral each cycle. So the rule is one election, and the CP 287C enforces it. The required Section 7519 payment exists for the same reason, to make the entity pre-pay the value of the deferral so the government is not out the time value of money. When that payment system breaks down and the election dies, the CP 287C is the bookend that tells you the whole structure is finished.
Here is a worked example of how a CP 287C lands on a desk. Say Hudson Design PSC, a personal service corporation in Manhattan, made a Section 444 election in 2019 to run a September 30 fiscal year. In 2023 the firm let its Section 7519 required payment lapse, so the election terminated. In early 2026 a new controller, not knowing the history, filed a fresh Form 8716 to grab that September 30 year again. The IRS answered with a CP 287C denying the second election. Hudson now files on the calendar year ending December 31, 2026, full stop. That is exactly the result a CP 287C is designed to produce.
We see this every year. A new bookkeeper or a new CPA inherits a client, sees a calendar-year filing, assumes a fiscal year would save money, and files Form 8716 without checking whether a prior Section 444 election ever existed. The CP 287C shows up weeks later and everyone is confused. The fix is boring but correct: pull the entity transcript, confirm the prior Section 444 history, and stop trying to re-elect. The edge case worth knowing is that a CP 287C does not, by itself, create a penalty or a balance due. It simply locks your tax year. If you also owe a Section 7519 required payment or a Section 280H amount from the old election period, that arrives on a separate notice, not on the CP 287C. If a CP 287C arrived and you are not sure what your prior Section 444 history looks like, our tax compliance team can pull the transcript and tell you in plain English what the notice means for your filing year. Start at new client inquiry and we will take it from there.
Why did I get a CP 287C notice from the IRS?
You got a CP 287C because the IRS records show a prior IRC Section 444 election for your entity that has already terminated, and you filed a new Form 8716 trying to elect a non-required tax year again. The CP 287C is the denial of that second attempt. The one rule that drives every CP 287C is simple: an entity gets one Section 444 election in its lifetime. Once it ends, it cannot be revived, and any new Form 8716 will draw a CP 287C. So the short answer to why you got a CP 287C is that the IRS already has your entity on file as having used its single election. You can confirm the agency’s wording on this denial at Understanding your CP287C notice.
The mechanics of how a Section 444 election dies are worth knowing, because that is what triggers a CP 287C. The election ends in any of these ways. The entity changes its tax year to its required year or to another permitted year. The entity fails to keep its Section 7519 required payment current. The entity becomes subject to the Section 280H limits as a personal service corporation and is penalized. Or the entity stops being the kind of pass-through that qualifies. Any of those events terminates the election permanently, and the next Form 8716 produces a CP 287C. The required-payment side of this is computed on Form 8752, explained at Instructions for Form 8752.
It helps to understand which entities even get into Section 444 territory, because that tells you who is exposed to a CP 287C. Only partnerships, S corporations, and personal service corporations can make the election, and only to keep a year-end no more than three months earlier than the required year. A calendar-year required entity, for instance, can elect a September 30, October 31, or November 30 year, nothing further back. So the universe of CP 287C recipients is narrow: pass-throughs that once held a short-deferral fiscal year and let it lapse. If your entity is a C corporation with a natural fiscal year, none of this applies and a CP 287C should not be reaching you at all.
Here is a real-number example of why a CP 287C appears. Riverside Partners LP elected a Section 444 year ending September 30 back in 2018, with a required payment that ran roughly 4,800 dollars a year on Form 8752. In 2022 the partnership wound down the fiscal year and moved to December 31, which terminated the election. In 2026 a partner wanted the September year back for a deal, so the firm filed Form 8716 again. The CP 287C came back denying it, because that 2022 termination was final. The 4,800 dollar payment history did not buy a second election. That is the typical fact pattern behind a CP 287C.
We see this every year, usually right after an ownership change or a CPA switch. The new advisor reads a calendar-year return, assumes nobody ever tried a fiscal year, and re-files Form 8716. The CP 287C is the IRS reminding everyone there is only one bite at this apple. The common mistake is treating the CP 287C as an error to appeal. It usually is not an error, it is the law working as written. The edge case: if you genuinely never made a prior Section 444 election and the CP 287C looks wrong, that points to an IRS posting error or a mismatched EIN, and you respond by phone with the notice number and the entity transcript. If you want a second set of eyes on a CP 287C before you respond, our corporate returns group handles fiscal-year and Section 444 issues for partnerships and S corporations all the time. You can reach us through new client inquiry.
Is there a deadline or amount due on a CP 287C notice?
A CP 287C notice carries no balance due and no payment deadline of its own. The CP 287C is purely a denial of your Form 8716 election, so there is nothing to pay on the notice itself. What the CP 287C does have is a practical deadline baked into your filing calendar: because the election is denied, you must file your annual return on your required tax year, which for almost every affected entity is the year ending December 31. So the real deadline tied to a CP 287C is your normal return due date on the calendar year, not a special date printed on the notice. The IRS confirms there is no amount due on this notice at Understanding your CP287C notice.
The mechanics matter here, because people confuse a CP 287C with the money notices in the same family. A CP 287C only governs your tax year. Any dollars that might be owed from the old Section 444 period, like a Section 7519 required payment computed on Form 8752 or a Section 280H amount for a personal service corporation, would arrive on a separate notice with its own due date. So if you are holding a CP 287C and worried about a deadline, separate the two questions. Question one, what tax year do I file on now. Answer, your required calendar year. Question two, do I owe anything from the terminated election. Answer, only if a different notice says so. The base CP 287 fiscal-year notice is described at Understanding your CP287 notice.
Because a CP 287C has no clock of its own, the dates that actually bind you come from the entity type. An S corporation files Form 1120-S by the 15th day of the third month after the calendar year-end, so March 15 in a normal year, with a six-month extension to September 15. A partnership files Form 1065 on the same March 15 schedule with the same extension. A personal service corporation filing Form 1120 runs to April 15 with an extension to October 15. The CP 287C does not change a single one of those dates. It just confirms that the year you measure them against ends December 31, not on the fiscal date you tried to elect.
Here is a dated example. Suppose Brightline Studio S Corp received a CP 287C dated March 9, 2026, denying a fresh Form 8716 for a January 31 fiscal year. There is no payment coupon on the CP 287C and no 21-day or 60-day clock to pay anything. The only deadline that matters for Brightline is its 2026 Form 1120-S due date on the calendar year, which lands March 16, 2027 with a normal extension to September 15, 2027. The CP 287C did not move those dates. It simply confirmed Brightline files on December 31, not January 31. That is how a CP 287C interacts with your real deadlines.
We see this every year: a client panics over a CP 287C thinking a payment is overdue, when the notice is just locking the tax year. The common mistake is mailing a check in response to a CP 287C. Do not do that, because there is nothing on the notice to pay and a stray check creates a misapplied-payment cleanup later. The edge case to watch is a short tax year. When an election terminates, the entity sometimes files a short-period return to bridge from the old fiscal year-end to December 31, and that short return has its own due date that a CP 287C will not spell out for you. Mapping that short year correctly is where mistakes get expensive. If a CP 287C left you unsure which return is due and when, our tax compliance team will lay out the exact dates for your entity. Begin at new client inquiry.
How do I respond to or dispute a CP 287C notice?
To respond to a CP 287C, first decide whether the notice is correct, because most of the time a CP 287C is right and needs no response at all. If your entity truly made a prior Section 444 election that terminated, the CP 287C is accurate, you take no action beyond filing on your required calendar year, and you keep the notice in the file. You only dispute a CP 287C when you have solid evidence that no prior Section 444 election ever existed, or that the one on record belongs to a different entity or EIN. So the response to a CP 287C is binary: confirm and file normally, or dispute with documentation. The IRS lays out the no-action path at Understanding your CP287C notice.
The mechanics of a dispute on a CP 287C run through the phone number printed on the notice, not through Tax Court, because a CP 287C is not a deficiency notice. You call, you reference the CP 287C notice number and the entity EIN, and you ask the representative to review the Section 444 election history on the account. Before you call, pull the entity transcript so you can see exactly what the IRS thinks happened and when. If the record shows an election that you can prove never applied to this entity, you provide the prior Form 8716 filings, the entity formation date, and the tax year history. Form 8716 itself, the document at the center of any CP 287C dispute, is described at About Form 8716.
Documentation is what wins or loses a CP 287C dispute, so gather it before the call rather than during. The three records that carry the most weight are the entity formation document with its date, the full account transcript showing every prior election posting, and copies of any earlier Form 8716 filings the entity actually made. If the dates do not line up, for example a 2015 election posted against an entity formed in 2021, that mismatch is your whole case. Keep your argument to the facts the transcript shows, because a CP 287C representative is checking records, not weighing opinions about which year-end you would prefer.
Here is a worked example of a legitimate CP 287C dispute. Meridian Group LLC formed in 2021 and filed its first-ever Form 8716 in January 2026 for a September 30 year. It got a CP 287C anyway. On the transcript, the firm found a 2015 Section 444 election posted under a transposed EIN that actually belonged to a different Meridian entity. That is a real error. The fix was a phone call referencing the CP 287C, plus a faxed copy of the 2021 formation documents proving the LLC could not have made a 2015 election. The IRS corrected the account and the original Form 8716 was processed. Absent that kind of clean proof, a CP 287C stands.
We see this every year: a client wants to fight a CP 287C purely because they dislike the answer, with no evidence the prior election never happened. That fight goes nowhere and wastes weeks. The common mistake is responding to a CP 287C in writing with an argument about why a fiscal year would be convenient. Convenience is irrelevant to a CP 287C, only the one-election rule matters. The edge case worth flagging: if the prior election terminated because of an unpaid Section 7519 deposit, sometimes catching up that history opens a conversation, but it still will not revive the dead election that the CP 287C denied. If you think your CP 287C is genuinely wrong, our IRS audit, refund and notice assistance team will build the response and make the call for you. Start at new client inquiry.
What happens if I ignore a CP 287C notice?
If you ignore a CP 287C, the most immediate consequence is that your denied fiscal-year election simply stays denied, and the IRS expects your return on the required calendar year ending December 31. A CP 287C does not impose a penalty for ignoring the notice itself, because there is nothing on the CP 287C to pay or sign. The danger in ignoring a CP 287C is more subtle: people who tried to elect a fiscal year often go on to file on that wrong fiscal year, which produces a late or misfiled return measured against the correct December 31 year. So ignoring a CP 287C is risky not because of the notice, but because it usually means you are about to file on a tax year the IRS will not accept. The agency states the required-year filing expectation at Understanding your CP287C notice.
The mechanics of what goes wrong are direct. Say you ignore the CP 287C and file a Form 1120-S for a September 30 year that the IRS already denied. That return is filed on a year the entity is not entitled to use, so the IRS treats your real return as the calendar-year return, due the following March. If you did not file that calendar-year return on time, you can face a late-filing penalty for an S corporation of 245 dollars per shareholder per month for up to 12 months under the 2026 figures. For a partnership the per-partner monthly penalty runs in the same range. Those penalties stack fast and they trace back to ignoring the CP 287C. The base fiscal-year notice family is covered at Understanding your CP287 notice.
There is a second cost that people miss when they ignore a CP 287C, and it lands on the owners. An S corporation or partnership return drives the Schedule K-1s that each shareholder or partner uses on their personal Form 1040. If the entity files on a denied fiscal year, the K-1s carry the wrong period, the owners file personal returns built on bad numbers, and the cleanup means amended business returns plus amended 1040s. So a single ignored CP 287C can spread from one entity return into four or five personal returns. That ripple is the real reason we tell clients never to sit on a CP 287C.
Here is a real-number example. Suppose Foundry S Corp has 4 shareholders and ignores a CP 287C, then files on a denied January 31 fiscal year. The IRS wants the 2026 calendar-year return by March 16, 2027. Foundry does not file the correct return until October 2027, seven months late. At 245 dollars times 4 shareholders times 7 months, that is 6,860 dollars in late-filing penalties, all flowing from ignoring a CP 287C and chasing a tax year it could not use. None of that would have happened if Foundry had read the CP 287C and filed on December 31.
We see this every year: a client tucks the CP 287C in a drawer, files on the fiscal year anyway, and gets surprised by a penalty notice eight months later. The common mistake is assuming a CP 287C is informational and therefore safe to ignore. It is informational, but the information is that your tax year is locked, and acting against that locked year is what triggers the cost. The edge case to remember is the short-period return that often needs to be filed when an election terminates, bridging the old fiscal year-end to December 31. Miss that short return and you compound the problem. If a CP 287C is sitting unanswered and you are not sure which return to file, our corporate returns team will get your entity onto the correct tax year before penalties start.
