Covered California can change your federal refund because the advance Premium Tax Credit is based on estimated household information. At filing, Form 8962 compares those advance payments with the credit you actually qualify for. A difference can increase your refund or create a balance; it is not automatically a tax on your insurance.
Read the 1095-A before entering it
Form 1095-A reports Marketplace coverage, monthly premiums, the benchmark premium and advance credit payments. Obtain it from Covered California, not from an employer's W-2. Check every covered person, month and policy. If the form is marked corrected, use the appropriate corrected information and keep the earlier version for your records.
A missing or incorrect benchmark premium can affect the calculation. Do not replace it with the premium you personally paid or guess a monthly number. Use Covered California's correction process or the appropriate official tool and instructions.
Reconcile estimates with actual circumstances
Common changes include a second job, self-employment profit, a spouse joining the household, a dependent moving between tax households or employer coverage becoming available. Marketplace estimates and tax-return income are not always the same figure. Review the definition used by Form 8962 rather than entering take-home pay.
| Result of reconciliation | Possible return effect |
|---|---|
| Allowed credit exceeds advance payments | Additional credit may reduce tax or increase the refund. |
| Advance payments exceed allowed credit | Excess payments may reduce the refund or increase the balance. |
| Household or policy information is wrong | Correct or allocate the information under the applicable instructions before calculating. |
Separate 2025 from 2026
The IRS states that repayment limits for excess advance credit no longer apply for tax years after 2025. For tax year 2026, the full excess must generally be repaid. Do not carry a 2025 repayment cap into a 2026 estimate. The tax year is the coverage year, not the year you happen to open the insurance account.
Bring a complete coverage file
- All 1095-A forms, including corrected forms and policies covering different household members.
- Income documents for the tax household and information about marriage, dependents or household changes.
- Employer coverage offers and dates when other insurance became available.
- Marketplace correspondence, premium records and prior-year returns if an allocation carries across years.
Report changes promptly to Covered California during the year. Waiting until tax filing may leave too much advance credit in place. If the balance is already due, review filing and payment options rather than omitting the 1095-A.
Marketplace tax questions
Does everyone with health insurance receive a 1095-A?
No. It concerns Marketplace coverage. Employer and other coverage can use different forms; they are not interchangeable with a 1095-A.
Can I skip the form because my refund drops?
No. Required reconciliation must be completed accurately. First check whether the income, household and monthly policy information are correct.
Are 2026 repayments capped like earlier years?
The IRS says repayment limitations were removed for tax years beginning after December 31, 2025. Use the rules for the coverage year, not a prior-year estimate.
What if my child appears on someone else's policy?
A shared policy can require allocation under Form 8962 instructions. Gather both policy and tax-household facts before deciding who reports each amount.
