What ACA Participants Need to Know Before They File
When tax season rolls around, many people enrolled in an Affordable Care Act (ACA) Marketplace plan are surprised to learn that their health coverage and their tax return are closely connected.
If you purchased coverage through the Marketplace, here’s what you need to remember when filing taxes — and how to avoid costly mistakes.
1. You Should Receive Form 1095-A
If you had Marketplace coverage for any part of the year, you’ll receive
Form 1095-A: Health Insurance Marketplace Statement.
This form includes:
- The months you had coverage
- The total premium for your plan
- The amount of
Advance Premium Tax Credit (APTC) paid on your behalf
- The “benchmark” premium used to calculate your subsidy
Do not file your tax return without it. The information on this form is required to complete IRS Form 8962.
2. You Must Reconcile Your Premium Tax Credit
If you received
Advance Premium Tax Credits (APTC) to lower your monthly premium, you are required to reconcile that amount when you file your federal tax return. When you received
Advance Premium Tax Credits, the government estimated your subsidy based on:
- Your projected annual income
- Household size
- Tax filing status
Because that was just an estimate, the IRS requires you to compare (reconcile) the estimated credit to what you actually qualified for based on your final income.
- If your actual income was
lower than estimated, you may qualify for
additional premium tax credit, increasing your refund.
- If your actual income was
higher than estimated, you may have to
repay some or all of the advance credits you received.
How Does This Reconciliation Happen?
Reconciliation happens when you file your federal tax return. If you received APTC, you will file your taxes using
Form 1095-A and
Form 8962. Form 8962 is attached to your Form 1040.
Most tax software completes this automatically once you enter your 1095-A information.
3. Changes in Income Matter
Common life events that affect your subsidy and your taxes include: raises or bonuses, job loss, starting self-employment, marriage or divorce, birth or adoption of a child, and a dependent no longer qualifying.
If these changes weren’t reported to the Marketplace during the year, it can result in a tax surprise.
4. Filing Status Is Critical
Premium tax credits are generally only available if you file
Married Filing Jointly (if married). Married individuals who file
Married Filing Separately are typically not eligible for premium tax credits, with limited exceptions for domestic abuse or abandonment situations.
This is an important planning conversation before tax filing.
5. Self-Employed Individuals Have Special Considerations
For self-employed clients:
- Marketplace premiums may be deductible as a self-employed health insurance deduction.
- However, the premium deduction interacts with the premium tax credit calculation.
This can create a circular calculation that tax software usually handles — but it’s important to understand the interplay to avoid errors.
6. If You Don’t File, Future Subsidies May Be At Risk
Even individuals who are not otherwise required to file taxes must file if they received advance credits. Failure to file and reconcile premium tax credits can result in:
- Loss of eligibility for advance premium tax credits in future years
- Delays in coverage renewals
Final Thoughts
ACA Marketplace coverage provides valuable financial assistance, but that assistance is tied directly to your tax return.
The key takeaway:
Your health insurance and your taxes are connected — and accuracy matters.
If you have questions about how income changes may affect your Marketplace subsidy, or if you anticipate life changes this year, it’s wise to review your coverage proactively rather than waiting for tax season surprises.
