IRS Notice CP 27
What IRS Notice CP 27 means
IRS Notice CP 27 is a notice that IRS records indicate you may be eligible for the Earned Income Credit but did not claim it on your tax return. 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 27 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 27 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 27
You received IRS Notice CP 27 because the IRS believes something connected to the account issue described in CP 27 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 27 matters
IRS Notice CP 27 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 27, 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 27, 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 27
Some people handle IRS Notice CP 27 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 27 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 27 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 27 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 a CP27 notice from the IRS mean?
A CP27 notice means the IRS looked at your filed tax return and thinks you may have qualified for the Earned Income Tax Credit but did not claim it. This is a notice that can put money in your pocket, which makes it one of the friendlier letters the IRS sends. The CP27 notice goes specifically to taxpayers who have no qualifying children, because the IRS has a separate notice, the CP09, for people who do have children. So if a CP27 notice landed in your mailbox, the IRS records show you worked, earned income within the limits, and appear eligible for the childless Earned Income Tax Credit that you left off your return. You can read the official write up at the Understanding your CP27 notice page. Far too many people toss this letter because they assume any IRS envelope means trouble, and they throw away money doing it.
The Earned Income Tax Credit is a refundable credit, which is the part that matters most. Refundable means you can get the money even if you owe zero tax. A worker with no children who owes nothing can still receive an Earned Income Tax Credit refund just for having earned income under the threshold. That is unusual. Most tax breaks only reduce what you owe and stop at zero, but the Earned Income Tax Credit keeps going and pays you the difference as a refund. For tax year 2025 the maximum Earned Income Tax Credit for someone with no qualifying children is 649 dollars. It is not a fortune, but it is real cash the IRS is offering to send you, and the CP27 notice is the invitation to claim it. The mechanics live in Publication 596, Earned Income Credit, which lays out every eligibility test in detail.
Here is a worked example. A single warehouse worker in the Bronx earned 14,500 dollars in 2025, had no kids, and skipped the Earned Income Tax Credit because he assumed it was only for parents. The IRS caught the omission when it matched his wage data against the credit rules and mailed him a CP27 notice. He completed the worksheet the notice included, mailed it back, and the IRS sent him a 649 dollar refund about seven weeks later. That money existed the whole time. He just had not claimed it on his return, and the CP27 notice fixed that without him having to amend anything.
We see this every year. The big mistake is assuming the Earned Income Tax Credit requires children. It does not. The childless Earned Income Tax Credit is exactly what the CP27 notice is about, and it covers single and married workers alike who fall under the income caps. The other mistake is throwing the CP27 notice away because it looks like junk mail or a scam letter. It is a legitimate IRS notice, and you can verify it against the official IRS site. One edge case to flag. The CP27 notice does not automatically pay you. You have to respond, which we cover in the next questions. If you want help confirming whether you actually qualify before you reply, our individual tax return preparation team will run the numbers for you and tell you straight.
One more thing about the CP27 notice worth knowing up front. The notice is generated by the IRS matching program, which compares the income and filing data on your return against the Earned Income Tax Credit eligibility rules. When the program sees earned income inside the range, no qualifying child, and no credit claimed, it kicks out a CP27 notice automatically. That automated origin is good and bad. Good, because it means the IRS proactively hunts for childless workers who missed the credit. Bad, because the program works off the data you reported, so if your return understated your earned income or misreported your filing status, the CP27 notice could be aimed at someone who does not actually qualify once the full picture comes out. That is why the worksheet exists as a second check.
Why did I get a CP27 notice if I do not have children?
You got a CP27 notice precisely because you do not have qualifying children. That is the entire reason this particular notice exists. Many people believe the Earned Income Tax Credit is a benefit only for families with kids, so workers without children routinely skip it on their returns without a second thought. The IRS knows this happens constantly, so when its records show that a childless taxpayer earned income within the eligibility range and did not claim the credit, it sends a CP27 notice to flag the missed money. The CP27 notice is the IRS saying you look eligible for the childless Earned Income Tax Credit, please claim it. The official source is the CP27 notice page, and it confirms the notice targets workers without a qualifying child.
To qualify for the childless Earned Income Tax Credit, you generally need to have earned income from work, fall under the income limits, be at least 25 and under 65 for the year, have a valid Social Security number, not be the qualifying child of another person, and not be claimed as a dependent on someone else’s return. For tax year 2025 the earned income ceiling for a single filer with no qualifying children is 19,104 dollars, and 26,214 dollars for married filing jointly. Your investment income must stay under 11,950 dollars for the year. The IRS issues a CP27 notice when your filed return shows you inside these bounds but with no Earned Income Tax Credit claimed. The detailed rules sit in the IRS guide on who qualifies for the EITC, and they are worth reading before you respond.
Here is an example. A 41 year old single barista in Manhattan earned 12,300 dollars in 2025, had no children, and filed a simple return claiming the standard deduction with no Earned Income Tax Credit. Her earned income was well under the 19,104 dollar limit, her investment income was zero, and she met the age test comfortably at 41. The IRS flagged the missing credit and sent a CP27 notice. After she responded with the worksheet she received the 649 dollar maximum childless Earned Income Tax Credit, a credit she had no idea applied to a single person with no dependents.
We see this every year. The most common mistake is that childless workers, especially younger ones just over 25 and older workers near the 65 cutoff, never realize they qualify and would have left the money on the table if the CP27 notice had not arrived. The other mistake is the opposite. Some people who get a CP27 notice do not actually qualify once you dig into the tests, often because a dependency or age issue knocks them out, and they claim it anyway, which can cause a later clawback. One edge case. If someone can claim you as a dependent, you are not eligible even with a CP27 notice in hand, and that catches a lot of students and young adults living at home. If you are not sure which bucket you fall in, our tax compliance team will check every test before you respond so you do not claim a credit you will later have to repay.
Age is the test that catches people most often with a CP27 notice, so it deserves a closer look. For the childless Earned Income Tax Credit you must be at least 25 and under 65 at the end of the tax year. A 24 year old who worked all year and earned well under the limit still does not qualify, and neither does a 65 year old, even one dollar over the age line on the last day of the year. The income tests can be met and the Social Security test can be met, but if the age falls outside that band, the CP27 notice does not change the outcome. Check your age as of December 31 of the tax year in question before you assume the credit is yours, because this single test disqualifies more CP27 recipients than any other.
How do I respond to a CP27 notice and claim the credit?
To respond to a CP27 notice you complete and return Form 15112, the Earned Income Credit Worksheet that the IRS includes with the notice. This is the action step, and the CP27 notice does not pay you anything until you take it. The IRS will not simply mail you a check based on the CP27 notice alone. You have to confirm your eligibility by working through Form 15112, signing it, dating it, and mailing it back in the envelope provided with the notice. The worksheet walks you through the Earned Income Tax Credit qualification questions one by one so you can confirm you actually qualify. You can see the official instructions on the CP27 notice page and pull a blank copy of Form 15112 directly if your notice arrived without one or you misplaced it.
The worksheet is a series of yes or no questions about your age, your Social Security number, your filing status, your dependency status, and your income. If you answer every question in the qualifying direction, you sign Form 15112 and send it back. If any answer disqualifies you, the worksheet tells you to stop right there, because you do not qualify for the Earned Income Tax Credit and should not return the form. This is the IRS protecting you from claiming a credit you are not entitled to, which would only come back to bite you later. Once the IRS receives your signed Form 15112, it reviews your answers, confirms eligibility against its records, and issues the Earned Income Tax Credit refund. The IRS generally sends the money in six to eight weeks, assuming you do not owe back taxes or other federal debts that get offset first.
Here is a worked example. A 58 year old single client of ours earned 16,800 dollars in 2025 doing part time clerical work, no children, no investment income. She got a CP27 notice with Form 15112 attached. We sat down together, answered the worksheet questions one at a time, confirmed she met the age, income, and Social Security number tests, signed it, and mailed it in the provided envelope. Seven weeks later her 649 dollar Earned Income Tax Credit refund arrived by direct deposit. The CP27 notice flagged it, the Form 15112 claimed it, and the whole thing took about fifteen minutes of actual work once we knew what we were doing.
We see this every year. The number one mistake is ignoring the CP27 notice entirely, which means the Earned Income Tax Credit money never comes because the form never goes back. No form, no refund, it is that simple. The second mistake is filling out Form 15112 carelessly, answering a question wrong, and either claiming a credit you do not deserve or disqualifying yourself by accident over a misread question. Read each question slowly and answer it honestly. One edge case. If you already filed an amended return claiming the Earned Income Tax Credit, do not also return Form 15112, because that double files the claim and gums up the works. If your situation has any wrinkle, a mid year move, a dependency question, or self employment income that changes your earned income figure, let our individual tax preparation team complete the worksheet with you so the response to your CP27 notice is right the first time.
Keep a copy of the Form 15112 you mail back, and note the date you sent it. This sounds minor, but it matters if the refund does not show up in the expected window. If eight weeks pass with no Earned Income Tax Credit refund and no further letter, you will want proof of when and what you sent so the IRS can locate your response in its system. Mail it in the envelope provided, which routes it to the correct processing unit, and resist the urge to also fax it or upload it elsewhere, because duplicate submissions of the same worksheet can cause the system to flag your claim for manual review and slow everything down. One clean submission, one copy kept, one date recorded.
How much is the credit and how long does a CP27 notice refund take?
The credit tied to a CP27 notice tops out at 649 dollars for tax year 2025 for a worker with no qualifying children. That is the maximum childless Earned Income Tax Credit, and it is the ceiling, not a flat amount everyone receives. The actual credit you get depends on your earned income, because the Earned Income Tax Credit phases in as you earn more, hits its peak in a middle band, then phases out as your income climbs toward the limit. A worker at the very bottom of the range or near the top gets less than the full 649 dollars, while someone sitting in the sweet spot of the income curve gets the maximum. The IRS publishes the exact figures by income and filing status in its Earned Income Tax Credit tables, which let you look up your own number.
On timing, once the IRS receives your signed Form 15112 confirming you qualify, it generally issues the Earned Income Tax Credit refund within six to eight weeks. That window assumes a clean response and no offsets in the way. If you owe back federal taxes, defaulted student loans, state tax debt, or past due child support, the Treasury Offset Program can reduce or absorb your Earned Income Tax Credit refund before you ever see a dollar of it. The CP27 notice does not shield the refund from legitimate offsets, and that surprises people who expected the full amount. The official six to eight week timeframe is stated on the CP27 notice page.
Here is a worked example showing the phase in. A single 29 year old earned only 4,000 dollars in 2025, no children. Because his earned income was low and sat early on the phase in curve, his Earned Income Tax Credit was not the full 649 dollars but roughly 306 dollars based on the credit rate for childless filers. He returned Form 15112 from his CP27 notice and the IRS sent the 306 dollars about six weeks later. Compare that to the Bronx warehouse worker earning 14,500 dollars who landed in the plateau of the curve and hit the full 649 dollar maximum. Same CP27 notice, different credit, all driven by where each worker fell on the income curve.
We see this every year. The common mistake is expecting the full 649 dollars regardless of income and then feeling shorted when the Earned Income Tax Credit comes in lower at, say, 200 or 300 dollars. The credit is a sliding scale tied to your earnings, not a fixed prize everyone collects. The other mistake is assuming the refund will arrive in the usual three week window people associate with regular tax refunds. A CP27 notice refund runs on the slower six to eight week worksheet review track because a person has to review your Form 15112. One edge case. Filing late in the calendar can push the timeline further because the IRS processes these manually and volume builds up. If your Earned Income Tax Credit refund is delayed past eight weeks or comes in smaller than you expected and you cannot tell whether it is the phase in or an offset, our IRS notice and refund assistance team can pull your transcript and trace exactly what happened.
It also helps to understand why the childless credit is so much smaller than the credit for families. The Earned Income Tax Credit was built primarily to support working families with children, so the credit amounts for filers with one, two, or three children run into the thousands of dollars, while the childless credit tops out at 649 dollars for 2025. That gap surprises people who heard the Earned Income Tax Credit described as a major benefit and then see a few hundred dollars on their own CP27 notice. The childless version is real and worth claiming, but it was designed as a modest credit, not a large one. Knowing that going in keeps the 649 dollar ceiling from feeling like a mistake when your worksheet comes back approved.
What happens if I ignore a CP27 notice?
If you ignore a CP27 notice, the simplest answer is that you forfeit money the IRS was ready to send you. There is no penalty for ignoring a CP27 notice, no interest charge, no collection action, because the CP27 notice is not a bill. It is an offer. The IRS is telling you that you appear to qualify for the Earned Income Tax Credit and inviting you to claim it by returning Form 15112. If you do nothing, the Earned Income Tax Credit simply never gets paid out to you. The credit does not deposit automatically just because the notice arrived. It waits on your signed worksheet, and if that worksheet never comes back, the money stays with the Treasury. The CP27 notice page makes clear the credit follows your response, not the other way around.
That said, ignoring a CP27 notice is not always permanent. The Earned Income Tax Credit is claimed on your tax return, and you generally have up to three years from the original filing deadline to claim a refund. So if you toss the CP27 notice this year and realize your mistake next year, you can usually still get the Earned Income Tax Credit by filing an amended return, Form 1040-X, for that tax year. You do not strictly need the CP27 notice physically in hand to claim the credit, since the notice is a prompt rather than the only legal path to the money. The amended return rules and the three year window sit in the Form 1040-X instructions, which spell out how far back you can reach.
Here is a worked example. A client ignored her CP27 notice in one year because she was convinced it was a scam, the kind of fake IRS letter she had been warned about. The 649 dollar Earned Income Tax Credit went unclaimed that year. Two years later, while we were preparing her current return, we reviewed her prior filings, caught the missed credit, filed a Form 1040-X for the earlier tax year, and recovered the full 649 dollars plus a small amount of interest the IRS added for holding it. Because she was still inside the three year refund window, ignoring the CP27 notice cost her time and some interest, but not the money itself.
We see this every year. The biggest mistake is assuming a CP27 notice is fake. Scammers do impersonate the IRS through fake letters and texts, but the IRS does send real CP27 notices through the mail, and you can verify any notice by checking the notice number against the official IRS site or calling the number printed on the letter. The second mistake is letting the three year window close. Wait too long after ignoring a CP27 notice and the Earned Income Tax Credit is gone for good, with no amended return able to recover it once the statute runs. One edge case. If you moved and never actually received the CP27 notice, you can still claim the Earned Income Tax Credit on an original or amended return as long as you qualify under the rules. If you think you missed a CP27 notice in a past year or are not sure whether a prior year credit is still recoverable, reach out through our new client inquiry page and our tax compliance team will review your last several returns and claim anything you left behind.
If you do decide the CP27 notice might be fraudulent and want to confirm before acting, do not call any phone number printed on a letter you distrust, because a scam letter would list a scam number. Instead, go directly to the official IRS website on your own, search the notice number, and compare the real CP27 description against what you received. You can also call the IRS main line listed on irs.gov rather than the letter. Real CP27 notices never demand payment, never ask for gift cards, and never threaten arrest. If your letter does any of those things, it is fake and you should report it. A genuine CP27 notice only ever offers you money and asks for a signed worksheet in return.
