Why Doesn’t My Income Match My 1095-A?
ACA Marketplace Reconciliation Explained (Form 8962 & Subsidy Payback)
Every tax season, we receive this question:
“My tax preparer says my income doesn’t match my 1095-A. Did we do something wrong?”
If you’re seeing a 1095-A income mismatch, take a breath.
In most cases, nothing is wrong.
Let’s walk through how Marketplace reconciliation works and why your income and your 1095-A are not supposed to “match.”
What Is the 1095-A?
If you had health insurance through the Marketplace (ACA plan), you receive Form 1095-A.
The 1095-A shows:
Your monthly premium
The benchmark (Second Lowest Cost Silver Plan)
The Advance Premium Tax Credit (subsidy) paid on your behalf
What it does NOT show:
👉 Your income.
So if someone says your income doesn’t match your 1095-A, technically that’s not possible — because income is not listed on that form.
Where Income Is Actually Compared: Form 8962
The comparison happens on IRS Form 8962.
This is where your tax preparer:
Reviews the income that was estimated on your Marketplace application
Compares it to your actual income for the year
Calculates whether you received the correct subsidy
This process is called ACA subsidy reconciliation.
What Is Marketplace Reconciliation?
When you enroll in an ACA Marketplace plan, you estimate your income for the upcoming year.
The government uses that estimate to calculate your monthly subsidy (Advance Premium Tax Credit).
At tax time, the IRS compares:
Estimated income (what was used to determine your subsidy)
Actual income (what you earned)
If those numbers are different, the subsidy is reconciled.
That is normal.
That is expected.
That is how the system is designed.
Do I Have to Pay Back My ACA Subsidy?
This is usually the real concern.
If You Earned More Than Estimated
If your actual income was higher than what was estimated on your Marketplace application, you may have received more subsidy than you qualified for.
This can result in:
Paying back some of the subsidy
Reduced refund
Or in some cases, a balance owed
The repayment amount depends on:
Final household income
Household size
Federal Poverty Level percentage
Whether repayment caps apply
This is not a penalty.
It is simply reconciling the advance tax credit.
If You Earned Less Than Estimated
If your income was lower than estimated, you may:
Receive additional subsidy
Get a larger tax refund
Many people are surprised to learn this works both ways.
Is Something Wrong With My 1095-A?
In most cases, no.
A 1095-A income mismatch does not mean the form is wrong.
The 1095-A reports:
Premium amounts
Subsidy amounts paid to the carrier
Your income is reconciled separately through your tax return.
Can My Insurance Agent Fix This Now?
Once the tax year has ended, your subsidy reconciliation is handled through your tax return.
An agent cannot retroactively change last year’s income.
However, going forward, your Marketplace application should reflect an accurate estimated income to prevent large adjustments in future years.
How to Avoid Large ACA Subsidy Paybacks in the Future
If you want to reduce the risk of paying back subsidy next year:
Update Income Changes Promptly
If your income increases or decreases significantly, report the change during the year.
Use Realistic Income Estimates
Especially if you are self-employed or have fluctuating income.
Work With a Tax Professional
If your income varies, proactive tax planning can help reduce surprises.
Frequently Asked Questions About 1095-A Income Mismatch
Why does my tax preparer say my income doesn’t match my 1095-A?
Because the 1095-A does not list income. Income is compared separately on Form 8962 during reconciliation.
What form reconciles Marketplace subsidy?
Form 8962 reconciles the Advance Premium Tax Credit with your actual annual income.
Can I change last year’s estimated income now?
No. Once the year ends, reconciliation occurs through your tax return.
What if I can’t afford to repay the subsidy?
Your tax preparer can review:
Repayment caps
IRS payment plan options
Whether any errors occurred in reporting
What if I never updated my income during the year?
Reconciliation will correct the difference. However, updating income during the year helps reduce large adjustments.
How This Applies to Jacksonville Residents
If you live in Jacksonville, Duval County, or surrounding Northeast Florida counties, plan availability and provider networks vary by ZIP code.
Some Medicare Advantage plans contract differently with Baptist Health, Mayo Clinic, Ascension St. Vincent’s, HCA Florida Memorial, HCA Florida Orange Park Medical and UF Health.
Before choosing a plan, Jacksonville residents should review:
Whether their doctors participate

The Bottom Line
If you’re dealing with a 1095-A income mismatch, it usually means the ACA reconciliation process is working exactly as intended.
It does not automatically mean:
The form is wrong
Your agent made a mistake
You did something improper
It means estimated income and actual income were different — and now the system is balancing the difference.
If your income has changed this year and you’re currently enrolled in a Marketplace plan, it may be wise to review your application and update your estimated income to prevent future subsidy surprises.
