An Applicable Large Employer opens the mail to a Letter 226-J and a proposed Employer Shared Responsibility Payment that runs into real money. Form 14764 is the ESRP Response form that answers it. The response is due by the date printed on the letter, generally 30 days out, and missing that date is how a proposed payment becomes a billed one.
Agreeing is simple: sign, pay or check the installment box. Disagreeing takes more care, because you attach a signed explanation and mark corrections on Form 14765 to support your position. The penalties at stake for 2025 assessments are indexed at $2,900 per full-time employee under §4980H(a) and $4,350 under §4980H(b), so the months you can document are the ones worth fighting for.
Key Takeaways
- Form 14764, ESRP Response, is filed only to answer IRS Letter 226-J. It is a response form, not a free-standing return, and it has no annual filing deadline.
- The response is due by the date printed on Letter 226-J, generally 30 days from the letter date. Extensions are available on request but are not automatic.
- If you agree, sign Form 14764 and return it with full payment (or check the installment box). If you disagree, attach a signed explanation, mark corrections on Form 14765 (the Employee PTC Listing), and include supporting documents.
- After review, the IRS sends a Letter 227 series acknowledgement (J/K/L/M/N/O) telling you whether the ESRP was eliminated, revised, or left unchanged, and what to do next.
- For 2025 assessments the indexed §4980H penalties are $2,900 per year under §4980H(a) and $4,350 per year under §4980H(b). The 30-employee reduction applies to the §4980H(a) penalty only.
- Only Applicable Large Employers (50+ full-time and FTE-equivalent employees) receive Letter 226-J. Tax-exempt and government employers that meet the threshold are subject too.
What Form 14764 is and why it matters
Letter 226‑J is not a bill, it is the IRS’s proposal. Form 14764 is your one-page response that drives everything that follows. You check agree, partial, or total disagreement, you sign, and you either include payment or send a detailed explanation with corrected codes and proof. The form, plus your attachments, leads directly to your Letter 227 outcome.
Here is what the IRS expects you to do, in plain English:
- Read every page in the packet, including the calculation table and Form 14765, which lists employees tied to premium tax credits.
- Decide if you agree or disagree and complete Form 14764 to match.
- If you disagree, write a clear statement, correct the monthly codes on Form 14765, and attach supporting documents, then return everything by the response date.
What happens if you do nothing
If you do not respond by the date on the letter, the IRS can assess the proposed amount, then issue CP220J as a bill. Interest accrues until you pay or get it resolved, and routine IRS collection tools are on the table. This is avoidable if you meet your first deadline.

A quick note on support. This article lives on Accountably’s Form 14764 blog. Accountably is offshore and outsourced accounting and tax staffing built for CPA, EA, and accounting firms, run by a CPA who has sat the review cycle. We place trained preparers, not resumes. When teams are buried in ACA cleanup and reporting, our standardized workpapers, multi‑layer reviews, and auditable checklists can compress review time without losing control. Mention us only where it helps you move faster with confidence, never as a sales detour.
When Letter 226‑J triggers Form 14764, and what to do first
You receive Letter 226‑J because the IRS matched your 1094‑C and 1095‑C filings to employee returns with premium tax credits, then calculated a proposed ESRP for the months that appear assessable. That letter includes Form 14764 and Form 14765, plus the monthly computation. Your job is to confirm or correct that story and send it back by the date shown.
The 30‑day window is real. The IRS states that the response is generally due 30 days from the date on the letter. If you need more time, call the IRS contact listed on your letter right away and request an extension (extensions are not automatic – the IRS must grant the request, so do not assume the response date has moved until you have written confirmation). Then keep proof of any call logs, emails, or faxes.
Immediate response steps
- Calendar the response deadline the day you open the envelope. Set internal reminders a week and three days before the due date. The IRS expects you to respond by that printed date.
- Assign roles. One owner for payroll data, one for benefits enrollment and contribution records, one for completing Form 14765, and one for drafting the signed explanation.
- Decide quickly: agree, partial, or total disagreement. This decision guides your evidence list and saves days.
- If you agree, complete and sign Form 14764, include payment per the packet instructions, and mail to the return address on the notice. If you prefer to pay electronically, EFTPS is a standard federal payment channel businesses use, and your packet will explain acceptable options for this assessment.
- If you disagree, check that box on 14764, attach a signed explanation, correct Form 14765 month by month, and include proof, then return everything to the address on your notice.
Use the return address and any transmission method shown in your letter. The IRS’s public guidance points you back to the address and instructions printed on your notice.
How the IRS processes your reply
After you file a complete response, the IRS sends a Letter 227 that tells you what they accepted and what happens next. 227K means reduced to zero, 227L means reduced but not zero, 227M means no change, 227J confirms you agreed to assess, and 227N reflects an Appeals conclusion. If the IRS eventually assesses and bills you, you will see CP220J, which also lists payment options.
A quick sanity check on penalty math
Two moving parts drive the ESRP, the A penalty and the B penalty. The dollar amounts are indexed each year. For 2026, the A amount is 3,340 per full‑time employee, minus the first 30, and the B amount is 5,010 per full‑time employee who received a premium tax credit (the 30‑employee reduction applies only to the A penalty under §4980H(a); there is no equivalent reduction for the B penalty under §4980H(b)). These figures are published by the IRS in Revenue Procedure 2025‑26. We will not re‑work the entire formula here, but you will use these annual numbers to spot obvious IRS math issues.
Why employers trip over this notice
- Line 14 and 16 code errors on 1095‑C for affordability, offer timing, or limited non‑assessment months.
- Missing measurement period documentation for variable‑hour staff.
- Affordability safe harbor applied inconsistently across months or employees.
- Payroll contribution changes midyear with no audit trail.
That is fixable with clean source records and a methodical update to 14765. You do not need heroics, you need a checklist and proof.
Documents to gather for a clean Form 14764 and 14765 response
Think of this as building a small case file. You want every number that affects your codes, affordability, and full‑time status ready to go, labeled, and legible.
Core packet
- Your filed 1094‑C and each 1095‑C for the year, with attention to Line 14 and Line 16 codes for every month listed on Form 14765.
- The IRS’s Form 14765 from your packet, which lists employees the IRS tied to premium tax credits and months it thinks are assessable.
Payroll and employment detail
- Monthly wages, hours, start dates, terminations, and measurement method documentation, to confirm full‑time status.
- For affordability testing, monthly employee contribution amounts for the lowest cost, self‑only plan that provides minimum value, plus safe harbor calculations. The IRS recognizes W‑2, rate‑of‑pay, and federal poverty line safe harbors.
Plan and enrollment proof
- Plan summaries showing minimum essential coverage and minimum value.
- Enrollment forms, waiver forms, and payroll deduction records that prove offers and costs for the employee.
Affordability safe harbors, updated thresholds
Affordability is not a single fixed percentage forever. The IRS sets a percentage each plan year.
- Plan years beginning in 2024 use 8.39%.
- Plan years beginning in 2025 use 9.02%.
- Plan years beginning in 2026 use 9.96%. Choose and apply a safe harbor by employee and month, then keep the math that shows the contribution was at or below that year’s limit.
Quick affordability reference table
| Year | Affordability percentage | Source |
| 2024 | 8.39% | IRS Rev. Proc. 2023‑29, IRB 2023‑37 |
| 2025 | 9.02% | IRS Rev. Proc. 2024‑35, IRB 2024‑39 |
| 2026 | 9.96% | IRS Rev. Proc. 2025‑25, IRB 2025‑32 |
Tip, if you use the FPL safe harbor, use the IRS affordability percentage for the plan year and the correct FPL table for your location and timing. Many non‑calendar plans can use the FPL in effect within six months before the plan year start, which is why you should document which table you used.
What a strong packet looks like
- A marked‑up 14765 with corrected codes for each disputed month.
- Side‑by‑side worksheets for W‑2, rate‑of‑pay, or FPL calculations, tied to payroll and plan documents.
- Copies of amended 1095‑C and, if needed, an amended 1094‑C.
- A signed, dated explanation, two or three pages, that walks the IRS through the corrections in the same order as 14765.
If your accounting firm is stretched thin during busy season, a standardized workpaper set helps a reviewer finish in minutes instead of hours. This is where a disciplined team, onshore or offshore, earns its keep, by delivering consistent naming, version control, and checklists that reduce revision loops. Accountably designs this kind of structure for firms that want review time down and reliability up.
If you agree with the proposed ESRP, how to complete Form 14764 and pay
Sometimes the fastest win is closure. If you review your packet and agree with the IRS’s math, Form 14764 makes the process straightforward.
Step by step
- Check “Agreement with proposed assessment” on Form 14764.
- Sign, date, and print your name and title.
- Choose your payment method. If you pay by check, include it with the form. If you use EFTPS, include the confirmation details that tie your payment to the notice.
- Include any pages the letter asks you to return and keep a full copy for your records.
- Mail everything using the return address and envelope that came with your Letter 226‑J. Keep proof of mailing.
Keep a simple packet: the signed Form 14764 on top, then your payment or EFTPS confirmation, then any pages the letter instructs you to return.
Practical tips from the field
- Do not wait until the last day. If the check goes out late or the EFTPS date is after the response deadline, interest can start to accrue.
- If cash is tight, call the number on your letter and ask about your options. Do this before the deadline.
- Save a PDF scan of everything, including the signed form and payment proof, in a single file named with your case number and response date.
If you disagree, complete Form 14764 with a clear, signed explanation
When you disagree in whole or part, your goal is to make it easy for the IRS to see your facts month by month. That means a precise Form 14764, a clean Form 14765 with corrections, and a signed explanation that connects the dots.
How to frame your written explanation
- Open with one paragraph stating you disagree in full or in part and why.
- Provide a short bullet list of the main issues, for example affordability coding, offer timing, or full‑time status.
- Add a section called “Corrections” that references Form 14765 line by line.
- Close with a one‑paragraph summary and a contact for follow up.
What to attach
- Corrected Form 14765 with updated codes for each disputed month.
- Source documents, for example payroll extracts, benefit contribution tables, enrollment or waiver forms, and any amended 1095‑C or 1094‑C.
- A signed, dated letter on company letterhead.
Payment choices when you disagree
Form 14764 lets you choose full payment, partial payment, or no payment while you dispute. If you pay in full and you are later right, the IRS can issue a refund or apply it to other liabilities. If you pay nothing and lose, interest accrues until paid. Choose based on cash flow and confidence in your support.
Using Form 14765 to adjust the proposed ESRP
Form 14765 is the Employee PTC Listing that sits at the heart of the IRS calculation. Treat it as a worksheet you can correct.
How to work the page
- Verify each employee’s name and truncated SSN.
- Focus on months without highlight, since those are months the IRS sees as assessable.
- For each month you believe is not assessable, enter the correct Line 14 and Line 16 codes that should have appeared on the employee’s 1095‑C.
- Tie each correction to a piece of proof and cite that proof in your explanation letter, for example “See Exhibit B‑3, payroll and deduction record, March.”
- If corrected 1095‑C forms are needed, prepare and attach them.
A quick example
A 180‑life employer received Letter 226‑J showing months flagged because Line 16 was blank. The company used the rate of pay safe harbor and offered affordable coverage. They corrected 14765 to add a 2H for months in limited non‑assessment and a 2F for months that met affordability. They attached payroll rate sheets and contribution calculations for each employee and month. The case closed with a zero balance in their Letter 227.
Reviewer‑friendly packet structure
- Tab 1, Form 14764, signed.
- Tab 2, Explanation letter, two to three pages.
- Tab 3, Corrected Form 14765 with a simple legend for code meanings.
- Tab 4, Evidence binder, sorted by employee and month, including payroll, plan docs, and enrollment or waiver proofs.
- Tab 5, Amended 1095‑C and, if relevant, an amended 1094‑C.
If your internal team is working at peak capacity, structure saves you. Accountably’s delivery model uses standardized naming, layered review, and checklists that make 14765 corrections and exhibits easy to audit. That kind of discipline shortens partner or manager review time without sacrificing quality.
Which affordability safe harbor should you use
Safe harbors are the backbone of your affordability story. Choose the one that best fits each employee‑month, then show your math.
The three safe harbors at a glance
| Safe harbor | What it tests | Good fit | Watch outs |
| W‑2 wages | Employee’s required monthly contribution compared to Box 1 W‑2 wages from your company | Stable salaried staff with predictable annual wages | Midyear pay changes or large pre‑tax deductions can move Box 1 and break affordability if you do not monitor |
| Rate of pay | Hourly rate on the first day of the month times 130 hours, or monthly salary, compared to the required contribution | Hourly or variable‑hour staff where you can point to a clear first‑day rate | Rate decreases, unpaid leave, or salary changes must be documented to support the first‑day assumption |
| Federal poverty line | Required monthly contribution compared to a fixed monthly FPL figure for a single employee | Employers who want a uniform contribution cap and administrative simplicity | May increase employer subsidy cost, so test budget impact before you commit |
Data you need on your desk
- For W‑2, final Box 1 wages for the calendar year by employee, plus monthly contribution totals for the lowest cost, self‑only minimum value plan.
- For rate of pay, the hourly or salary rate on the first day of the month, scheduled hours for hourly staff, and the monthly employee premium.
- For FPL, the correct single‑employee FPL figure for your location and plan year and the applicable affordability percentage for that plan year.
How to apply a safe harbor cleanly
- Anchor to the plan year. Affordability percentages change by year, so lock your tests to the plan year in play.
- Document first‑day rates if you use rate of pay. Screenshots from HRIS or payroll systems work well.
- Keep a one‑page calculator template. Consistent layout reduces reviewer time and error.
Common pitfalls and how to avoid them
- Mixing safe harbors inside a single employee‑month. Use one method per employee‑month and say which one you used.
- Relying on memory for midyear rate changes. Print the rate change history and tag the first‑day rate.
- Leaving Line 16 blank when you could have used a code that shields the month. Blank often equals assessable.
A short story you can copy
“I thought we were fine,” a payroll manager told me, “but we changed our hourly rate tables in March and never updated the affordability calculator.” Once we tied the rate of pay tests to the first day of each month and corrected the codes on 14765, the proposed amount fell by more than half. The IRS does not need a novel, it needs accurate months, codes, and math.
How to update 1094‑C and 1095‑C codes to support your response
If your 1095‑C codes are wrong, fix them. Your packet is stronger when the IRS sees amended forms that match your 14765 corrections.
Update checklist
- Recalculate Line 14 and Line 16 codes for each affected employee and month.
- Prepare amended 1095‑C forms and, if the transmittal was affected, an amended 1094‑C.
- Include a change log in your explanation letter. List each employee, months changed, old code, new code, and the reason.
Simple documentation map
| Action | Documentation |
| Correct Line 14 and 16 | Amended 1095‑C copies, tied to payroll and contribution proofs |
| Update ALE or offer status | Amended 1094‑C with a short note if control group or headcount status changed |
| Prove affordability | Calculator pages, payroll extracts, plan contribution tables, and any rate sheets |
| Explain everything | Signed statement that connects each change to the code and the proof |
Quality control before you mail
- Reconcile employee counts across 1094‑C, 1095‑C, and your 14765 list.
- Confirm case number and tax year on every page.
- Put your explanation letter and 14765 at the front so a reviewer can follow your logic in order.
Where to send Form 14764 and supporting documents
Use the pre‑addressed envelope and return address that came with your Letter 226‑J. That address is tied to your case and routes your packet to the right IRS unit. Do not send it to a general IRS address. Keep a copy of everything and proof of mailing or transmission.
Use the pre‑addressed 226‑J envelope, include all required forms, and keep proof of delivery. Misrouting can cause delays or an unintended assessment.
What to expect after you file Form 14764
The IRS will send a Letter 227 that tells you the outcome.
- 227K, your dispute was accepted and the ESRP is eliminated.
- 227L, your dispute was partially accepted and the ESRP is reduced.
- 227M, the IRS did not change the proposed amount.
- 227J, you agreed to assessment and the case closes pending payment.
- 227N, Appeals issued a determination.
Track all dates listed. If you owe, follow the payment instructions. If you disagree with 227M, use the appeal options in your letter, and respond by the appeal due date.
Response timelines and your follow‑up
- Expect a few weeks to a couple of months for a 227, depending on complexity and season.
- If the IRS requests more information, reply by the stated date with a focused packet that answers the exact questions.
- If you do not receive a 227 after a reasonable period, contact the IRS employee listed on your notice to confirm receipt.
Common Mistakes We See Every Season
Most ESRP responses fail in the same handful of ways. Catch these before the 30-day window on Letter 226-J closes and you save the client months of follow-up letters and avoidable interest under IRC §6621.
Reusable Checklists
These three checklists move straight into a firm SOP for ESRP cases. Print them, paste them into the engagement template, or load them into the task system – the items are written to be cleared one at a time.
Letter 226-J intake packet
- Date-stamp the envelope and the letter on receipt; calendar the response date printed on Letter 226-J (generally 30 days from the letter date).
- Identify the assessment year on the letter and pull that year's Forms 1094-C and 1095-C from the client file.
- Pull the Form 14765 Employee PTC Listing from the Letter 226-J packet and reconcile the employee count against the 1095-C summary for the assessment year.
- Confirm Form 2848 is on file naming the firm partner who will sign; if only Form 8821 is on file, request a new POA before drafting.
- Pull payroll registers, plan documents, and offer-of-coverage notices for every month flagged on the PTC Listing.
- Tag the case as agree, disagree, or partial-disagree based on a first-pass review of the PTC Listing.
- Confirm the §4980H subsection at issue – (a) for the 95% substantial-coverage failure or (b) for the affordability / minimum-value failure – before any calculation.
Affordability safe-harbor review
- Confirm the affordability percentage for the assessment year; 9.02% applies to 2025 plan years, with older years using the year's published rate.
- Pick one of the three §4980H(b) safe harbors per category of employee: W-2 wages, rate of pay, or federal poverty line.
- For the W-2 safe harbor, compare each employee's Box 1 W-2 wages × the year's percentage to the lowest-cost self-only employee contribution.
- For the rate-of-pay safe harbor, use hourly rate × 130 hours × the year's percentage as the affordability ceiling.
- For the FPL safe harbor, use the prior-year mainland FPL for a one-person household ($15,060 for 2025 plan years) × the year's percentage.
- Verify minimum value: the employer plan must have an actuarial value of at least 60% to satisfy §4980H minimum-value coverage.
- Document the chosen safe harbor and the supporting calculation for every disputed employee-month.
Disagreement response packet
- Form 14764 signed under penalties of perjury by an authorized officer or POA, with the disagreement box checked.
- Dated written explanation referencing each disputed month and the safe harbor or coverage offer that applies.
- Form 14765 with the indicator code corrected in the column for each disputed month.
- Supporting documents per employee-month: offer letter, plan SBC, payroll register, enrollment confirmation, signed waiver if applicable.
- Form 2848 if a CPA, EA, or attorney is signing or corresponding on the client's behalf.
- Cover sheet mirroring the IRS office address printed on Letter 226-J; certified mail with return receipt to that exact address.
- Internal copy archived for at least seven years alongside Letter 226-J and any Letter 227 follow-up.
Keep 14764 Season From Stalling
Letter 226-J cases land at the worst possible time – on a fixed 30-day clock with no annual rhythm to prepare around. According to IRS guidance under IRC §4980H, 226-J packets are typically issued two to three years after the relevant 1095-C filing year, so the payroll registers, plan documents, and offer-of-coverage notices that prove the client's position are already buried in archives. With the indexed 2025 amounts of $2,900 under §4980H(a) and $4,350 under §4980H(b), a single mishandled month can turn into a five- or six-figure exposure.
The fix is structural, not heroic. Treat every 226-J as a stand-alone engagement with its own packet, its own reviewer, and its own calendar – not as something the manager fits between returns. The minimum production discipline that keeps the 30-day clock from turning into a 90-day scramble looks like this:
- Build a single 226-J intake template that captures the assessment year, the response date, the §4980H subsection at issue, and the POA status on day one.
- Reconcile the Form 14765 PTC Listing against the 1095-C file before any tactical decision; mismatches there drive most disagreements.
- Standardize the affordability analysis (W-2, rate of pay, or FPL) per category of employee, with the year's correct percentage (9.02% for 2025 plan years) locked at the top of the worksheet.
- Separate the §4980H(a) headcount-minus-30 worksheet from the §4980H(b) per-PTC-employee worksheet so the 30-employee exclusion never bleeds into the (b) calculation.
- Calendar both the Letter 226-J response date and the eventual Letter 227 decision points so the 30-day Appeals window after 227-L or 227-M is not missed.
Capacity is the hard part. ESRP responses pull senior time at the same moment the tax production calendar is full, and most firms do not have a second reviewer ready when 226-J packets land. Accountably's taxation delivery teams handle the packet build – intake, PTC reconciliation, safe-harbor worksheets, and Form 14765 corrections – so the partner only steps in for the final sign-off and the strategic call.
FAQs
Can I authorize someone to handle Form 14764 for me
Yes. You can use a power of attorney or third‑party authorization that spells out access and duration. Specifically, attach Form 2848 (Power of Attorney) – Form 8821 (Tax Information Authorization) only allows the representative to receive information, not to sign Form 14764 on your behalf. Include it in your packet and make sure your representative monitors all mail and deadlines.
How do I ask for more time to respond
Call the IRS contact listed on your Letter 226‑J right away. Request a short extension, confirm the new date, and keep written notes of the call. If you are still gathering records, ask for the exact fax or address they want you to use.
Will this affect an ongoing IRS audit
Usually no, but keep your positions consistent. If issues overlap, let your examiner know you filed a 226‑J response and share any information that affects both cases.
Can I send my response electronically
Your letter will state which transmission options are allowed for your case. Follow those instructions exactly, attach legible PDFs, and save the confirmations with timestamps.
What if we went through a merger or acquisition
Successor rules can carry ESRP responsibility into the combined company. Align measurement periods, controlled group status, and offer records across entities and document who was responsible for which months.
