IRS CP27 Notice: You May Qualify for the Earned Income Credit (2026)

By Angeline Balsitis, EA · Reviewed by Melissa Ly, Chief Tax Officer · Published June 26, 2026 · Updated July 7, 2026 · Editorial Standards

You braced for a bill when you saw the IRS return address — most 1099 workers do. Instead, this letter says the government may owe you, and that's exactly why so many CP27s end up in the junk drawer: it reads too good to be true. It isn't. The CP27 is a real IRS notice with real money behind it — but only if you respond correctly.

Two things make a CP27 different from almost every other IRS letter: it comes with its own claim form (Form 15112) stapled inside, and ignoring it costs you money instead of triggering collections. The image below shows exactly what a real CP27 looks like and where to look for the parts that matter, so you can confirm yours is genuine before you fill anything out.

Why you got a CP27 notice

A CP27 notice means the IRS matched the income on your return against the Earned Income Tax Credit tables and found you may qualify — with no qualifying child — for a credit you never claimed. The IRS screens millions of processed returns for exactly this, and mails CP27s to filers whose income lands in the eligible range.

For a 1099 contractor, the trigger is usually your net Schedule C profit. Your gross receipts might look healthy, but after mileage, supplies, and platform fees, the profit line can drop below the EITC ceiling — and the IRS's computers notice even when you don't.

Here's the critical nuance: the IRS screens on what its computers can see, but it can't verify every eligibility rule on its own. That's why the notice asks you to confirm eligibility on the worksheet instead of just sending a check. A CP27 is an invitation to claim money — not a determination that you qualify.

If you're trying to make sense of IRS mail in general, our decoder on why did I get a letter from the IRS covers the whole system. This page covers only the CP27 — and everything you need to answer it is right here.

What happens if you ignore a CP27

Nothing the IRS does gets worse if you ignore a CP27 — but the refund it points to quietly expires, generally 3 years after your return's original due date. The sequence looks nothing like a collection-notice escalation. It's an erosion:

1. Silence. The IRS usually does not send a second request. There's no CP27 follow-up chain the way balance-due notices escalate — this was likely your one prompt.
2. The refund statute keeps running. Every month you wait is a month off the roughly 3-year window to claim the money. If the notice sat unopened for a while, part of the clock is already spent.
3. The window closes. Once the refund statute expiration date passes, the credit becomes legally unclaimable. The money stays with the Treasury forever — the same hard wall we cover in can I still get a refund from 3 years ago.
4. If you owe on other years, you lose twice. An unclaimed credit could have been applied against a balance that's growing with interest. Skipping the worksheet means paying that debt with money the IRS was offering back to you.

One more thing a CP27 will never do: turn into an audit because you ignored it. Declining to claim a credit is always allowed. The only penalty is self-inflicted — the refund never arrives.

Do you actually qualify? The EITC without a qualifying child

The EITC without a qualifying child is the strictest version of the credit: income limits sit around $19,000 for single filers in recent years (higher for joint filers), and an age window of 25 through 64 knocks out younger and older workers entirely. Before you sign Form 15112, walk every line of this table:

Notice what the IRS can't fully see when it mails a CP27: whether someone else claims you as a dependent, where you lived during the year, and whether your Schedule C numbers were accurate in the first place. If any row above disqualifies you, don't sign the worksheet — signing an eligibility form you know is wrong creates a problem far bigger than a missed credit.

A CP27 worked example: 1099 contractor, $54,600 in gross receipts

Say you're a single 34-year-old contractor whose 1099-NECs total $54,600 in gross receipts. That sounds far too high for the EITC — until Schedule C does its work. This is a hypothetical, but the mechanics are exactly how the IRS runs the math:

• Gross receipts: $54,600
• Business expenses (mileage, phone, supplies, platform fees): $38,400
• Schedule C net profit: $54,600 − $38,400 = $16,200
• Earned income for EITC purposes (net earnings from self-employment): $16,200 × 0.9235 ≈ $14,961

For the EITC, you're a $14,961 earner — not a $54,600 one. Using recent-year figures for a single filer with no qualifying child (the exact numbers adjust for inflation annually), the credit tops out around $650 and phases out at 7.65 cents per dollar of income above roughly $10,600. So: $650 − [0.0765 × ($14,961 − $10,600)] ≈ $650 − $334 ≈ a credit of roughly $300. Form 15112 and the IRS compute the precise amount for your year — you don't have to.

Now the contractor-specific wrinkle. If you never paid the self-employment tax on that $16,200 profit — a common first-year miss we break down in self employment tax owe irs — the CP27 credit doesn't arrive as a check. It's applied against your balance first, shrinking both the debt and the interest compounding on it. Still worth claiming, just don't plan around the deposit.

And the flip side: if you had skipped your expenses and reported the full $54,600 as profit, no CP27 would ever have arrived — you'd be miles above the limit. Accurate expenses are what put you in range. But the line runs both ways: you can't omit real expenses to boost the credit, and Schedule C numbers bent to hit the EITC sweet spot are a classic exam trigger.

How to respond to a CP27 notice, step by step

1. Match the notice to your return. Confirm the tax year and name on the CP27 match a return you actually filed, and check your IRS online account to make sure a refund hasn't already been issued for that year.
2. Check every eligibility requirement. Go line by line through the rules for the EITC without a qualifying child — age, dependency, Social Security number, investment income, filing status — before you sign anything. If any line disqualifies you, do not return the worksheet.
3. Complete Form 15112. Fill out the Earned Income Credit worksheet attached to your notice, answer every question honestly, and sign and date it — both spouses must sign on a joint return.
4. Mail it back and keep a copy. Send the completed worksheet in the envelope provided or to the address printed on your notice, and keep a photocopy or a photo as proof you responded.
5. Track the response. Give the IRS typically 6 to 8 weeks to process the worksheet, and watch your IRS online account for the credit posting or a refund date.
6. Follow up if nothing arrives. If more than eight weeks pass with no refund and no letter, call the number printed on the CP27 — or contact the Taxpayer Advocate Service if the delay is causing you financial hardship.

What happens after you mail Form 15112

The IRS typically processes a returned CP27 worksheet in about 6 to 8 weeks — and with the IRS workforce down roughly 27% after the 2025 cuts, the slow end of that range is the realistic one in 2026. Here's the sequence:

That offset row deserves emphasis. If you owe federal back taxes, child support, or certain other government debts, the refund can be intercepted before it ever reaches your bank — the mechanics are covered in our guide to the Treasury Offset Program tax refund rules. An offset is not a rejection: the credit was allowed; it just went to a debt instead of your account, and you'll get a notice saying where it went.

CP27 vs. CP09 and the other EITC notices

The CP27 is one of a family of IRS credit-and-refund letters, and each demands a different response — mixing them up is the most common CP27 mistake we see. Here's the map:

The one that trips people up most: if your CP27 says "no qualifying child" but you actually have one — a child who lived with you more than half the year and meets the relationship and age tests — don't use Form 15112. Amend the return instead. The EITC with even one qualifying child is worth several times the no-child credit, and the worksheet path locks you into the smaller number. And if the IRS changed your return and adjusted your refund rather than inviting a claim, you're looking at a different letter entirely — see our CP12 notice guide for that one.

When you can handle a CP27 yourself

Most people can handle a CP27 alone: the worksheet takes about ten minutes, costs nothing, and carries no downside if you honestly qualify. If your return was accurate, you clear every eligibility line, and you owe the IRS nothing, fill out Form 15112 tonight and mail it — you don't need anyone's help, including ours.

Experienced help changes the outcome in four specific situations:

• You have a qualifying child the IRS missed. An amended return claiming the with-child EITC pays far more than the worksheet — but it has to be built correctly.
• You have unfiled years or back taxes. The order you fix things in determines whether this credit shrinks your debt efficiently or vanishes into a mess of offsets.
• Your Schedule C was wrong. If income or expenses were misreported, signing an eligibility worksheet on top of a flawed return compounds the problem. Fix the return first.
• Your EITC was disallowed before. Prior disallowance adds the Form 8862 requirement and extra scrutiny — worth getting right the first time.

Terms on your CP27, decoded

• Earned Income Tax Credit (EITC): a refundable credit for lower-income workers — "refundable" means it can pay you even if you owe no tax.
• Form 15112: the Earned Income Credit worksheet attached to a CP27; signing and returning it is how you claim the credit for that year.
• Qualifying child: a child meeting the IRS's relationship, age, and residency tests; having one moves you from the CP27 (Form 15112) path to the CP09 (Form 15111) path — and to a much larger credit.
• Earned income: wages plus net self-employment profit — for 1099 workers, the Schedule C bottom line, not gross receipts.
• Refund statute expiration date (RSED): the deadline — generally 3 years from the return's due date — after which an unclaimed refund is permanently forfeited.
• Treasury Offset Program: the government-wide system that intercepts refunds to pay federal tax debts, state taxes, child support, and certain other obligations before you're paid.

CP27 notice questions, answered

Your next 24 hours

1. Find two things on the notice: the tax year in the upper corner, and the Form 15112 worksheet attached behind the letter. Confirm the year matches a return you filed — then compare it against the official IRS page, Understanding your CP27 notice, to verify it's real.
2. Gather three documents: your tax return for that year (including Schedule C if you're a 1099 worker), your 1099s, and your Social Security card or a record of your SSN. That's everything the worksheet asks about — the full eligibility rules live on the IRS's Earned Income Tax Credit page.
3. Get a second set of eyes before you sign. If anything above gave you pause — a possible qualifying child, back taxes, a shaky Schedule C — get a free review at the 2-minute form or call (888) 825-7779. The refund window only runs one way, and it's already running. If the IRS later stalls on a worksheet you've submitted and the delay causes hardship, the Taxpayer Advocate Service can intervene for free.
