Every February, ACA brokers field calls from enrolled clients who received a Form 1095-A in the mail and do not know what to do with it. Most of them have a straightforward question: why does the IRS say they owe money? Usually the answer is on line 24 of Form 8962, which shows the difference between the APTC they received and the APTC they were entitled to based on what they actually earned. Both numbers trace back to the 1095-A. Brokers who understand the flow stop being surprised by the February call. Brokers who explain it at enrollment stop getting it.
Key Takeaways
- Form 1095-A has three columns: the monthly enrollment premium, the monthly SLCSP premium for the household, and the monthly APTC paid to the carrier. Clients need all three to complete Form 8962.
- Form 8962 reconciles the APTC the client received against the APTC they were actually entitled to, based on final annual income. If income was higher than projected, the client may owe some APTC back.
- Income changes during the year are the leading cause of unexpected tax bills at reconciliation time. Clients who receive a raise, add freelance income, or change jobs mid-year often do not update their Marketplace income estimate.
- Brokers who explain the reconciliation at enrollment prevent February calls. The explanation takes two minutes. The call takes thirty.
- APTC repayment is capped for households under 400 percent FPL. Above that threshold, the full excess APTC must be repaid. Clients close to the income cliff have the most reconciliation risk.
What Form 1095-A is and who receives it
Form 1095-A is issued by the Health Insurance Marketplace to every household that was enrolled in a Marketplace plan at any point during the calendar year. It is not issued by carriers. It is not the same as a 1095-B or 1095-C, which come from employers and carriers for other types of coverage. A client who was enrolled in a Marketplace plan for even one month in the calendar year receives a 1095-A for that year.
The form covers enrollment month by month and has three columns. All three are required to complete Form 8962 at tax time. Clients who hand their tax preparer a tax return with a Marketplace plan but no 1095-A will be asked for it before the return can be filed correctly.
The three columns on Form 1095-A
| Column | Label | What is in it | Used for |
|---|---|---|---|
| A | Monthly enrollment premium | The full monthly premium for the plan the client enrolled in | Part of the 8962 calculation; confirms what the plan actually costs |
| B | Monthly SLCSP premium | The premium for the second lowest cost Silver plan available to the household in their rating area for each month | The APTC benchmark. Line 11b on Form 8962 uses the annual SLCSP total to compute the maximum allowable credit. |
| C | Monthly advance APTC paid | The dollar amount of APTC the federal government paid directly to the carrier each month | Compared against the actual allowable credit on 8962. If Column C total exceeds the allowable credit, the excess must be repaid. |
Column B is where the SLCSP appears. The SLCSP is the second lowest cost Silver plan available to the specific household in their rating area, calculated for each month of enrollment. It changes if the household composition changes, if the household moves, or if plan availability in the county changes between months. For a full explanation of how the SLCSP is determined and why it matters as the APTC benchmark, see what is SLCSP and how it is calculated.
How Form 8962 uses the 1095-A
Form 8962 is the Premium Tax Credit reconciliation form filed with the federal tax return. It compares two numbers: the APTC actually paid to the carrier on the client's behalf (Column C totals from the 1095-A) and the allowable APTC based on the household's actual annual income and the SLCSP benchmark (Column B totals from the 1095-A).
If the APTC paid exceeds the allowable amount, the client must repay the difference, subject to repayment caps for lower-income households. If the allowable amount exceeds what was paid, the client receives the difference as a refundable tax credit. The form handles both directions. The direction depends almost entirely on how accurately the client estimated their income at enrollment compared to what they actually earned.

Reconciliation example: the income that changed mid-year
To illustrate: a single adult enrolled in January with projected annual income of $38,000, qualifying for $310 per month in APTC. In March, they accepted a new position with a higher salary. Their actual annual income for the year was $54,000. At tax time, Form 8962 compares the $3,720 in APTC paid through the year against the allowable credit based on $54,000. At $54,000, the allowable APTC is roughly $160 per month, or $1,920 for the full year. The client owes the $1,800 difference.
The client in this example did nothing wrong at enrollment. Their income estimate was accurate in January. The problem is that Marketplace income estimates are static unless the client actively updates them. A client who updates their income estimate in March would have had their monthly APTC reduced for the remainder of the year, significantly reducing the reconciliation amount at tax time.
Illustrative example. Actual APTC amounts depend on household composition, rating area, SLCSP benchmark, and the specific plan year. APTC repayment caps apply for households below 400 percent FPL and are adjusted annually by the IRS.
The income update the client never makes
Clients who receive a raise, start freelance work, add a part-time job, or change employment status mid-year rarely think to update their Marketplace income estimate. They enrolled in January, their plan works, and the monthly premium is what they expected. The APTC adjustment is invisible until February of the following year.
Brokers who set this expectation at enrollment reduce the problem significantly. The instruction is simple: if your income changes by more than 10 percent from what you reported at enrollment, log into your Marketplace account and update the income estimate. The system will recalculate APTC for the remaining months of the year. It will not fix past months, but it reduces the gap.

The repayment cap for lower-income households
For households with income below 400 percent of the federal poverty level, the IRS limits how much excess APTC a client must repay. The cap is set by income tier as a percentage of FPL and is adjusted annually in the Form 8962 instructions. A household at 150 percent FPL with an APTC overpayment of $2,000 may owe only a fraction of that amount under the cap.
Households above 400 percent FPL have no cap. If a client projected income just below 400 percent FPL and actually earned above it, the full excess APTC is owed without a repayment limit. This is the income cliff problem. Clients near the 400 percent FPL boundary have meaningful reconciliation risk if their income comes in higher than estimated. The conservative approach is to set the income estimate on the higher side for those households rather than maximizing APTC upfront.
What to tell the client before they leave the enrollment call
Three things. You will receive a Form 1095-A in January. Give it to your tax preparer or use it to complete Form 8962 on your own return. If your income changes significantly during the year, update it in your Marketplace account. That is the full explanation. Most clients will not need more. The ones who do need more will have the right question to ask when they call.
FAQ
Questions brokers and clients ask about Form 1095-A and APTC reconciliation.
What if a client lost their Form 1095-A?
The 1095-A is available in the client's HealthCare.gov account under 'Tax Forms.' State-based exchange clients can access it through their state exchange account. The form is typically available by late January. If a client cannot access their account, they can call the Marketplace directly. Brokers who set this expectation at enrollment save a call in February.
Does a client need Form 1095-A if they did not receive APTC?
Yes. Anyone who enrolled in a Marketplace plan receives a 1095-A, regardless of whether they received APTC. If Column C is all zeros, the reconciliation on Form 8962 is simple, but the form is still required to document the enrollment. Tax preparers who do not receive the 1095-A will ask for it.
Is there a cap on how much APTC a client must repay?
Yes, with conditions. For households with income below 400 percent FPL, the IRS sets a repayment cap that limits how much excess APTC must be repaid. The cap is based on income as a percentage of FPL. Households above 400 percent FPL must repay the full excess APTC with no cap. The specific cap amounts are in the Form 8962 instructions and are adjusted annually.
What should a client do if their income changes significantly during the year?
Update the income estimate through the Marketplace as soon as the change is known. This adjusts the monthly APTC going forward. It does not change APTC already paid in prior months. The earlier the update, the smaller the reconciliation variance at tax time. Brokers should remind clients of this at enrollment and in mid-year check-ins.
Can a client get more APTC back at tax time if they earn less than projected?
Yes. If a client's actual annual income is lower than what was estimated at enrollment, the allowable APTC on Form 8962 will be higher than what was actually paid. The difference is a refundable tax credit, meaning the client can receive it even if they owe no federal income tax otherwise. This is the less common direction of reconciliation but important for clients who experience income drops mid-year.
