In the United States, Marketplace subsidies can lower what you pay for individual health insurance in two different ways: a premium tax credit can reduce your monthly premium, while cost-sharing reductions can lower your share of covered medical costs. Whether you qualify—and how much help you receive—depends on your tax household, projected income, state, available plans, and access to other coverage. The Marketplace application gives an individualized estimate; your final premium tax credit is settled on your federal tax return.
How do health insurance subsidies work?
The main federal premium subsidy is the premium tax credit (PTC), a refundable tax credit for eligible people who enroll in qualifying coverage through a Health Insurance Marketplace. You can have some or all of an estimated credit paid directly to your insurer during the coverage year, lowering the premium you owe each month. Or you can take none in advance and claim the allowed credit when you file your federal tax return.
The Marketplace estimates your eligibility from the information in your application. The final credit is based on your actual circumstances for that tax year, so an advance amount is not a guaranteed final amount. The amount can vary with household income and size, location, and the cost of available plans.

There is no single income figure that determines eligibility for everyone. The IRS framework considers whether you enrolled through a Marketplace, household income, tax filing and dependency circumstances, and whether you or another enrolled household member is eligible for certain other coverage.
- Marketplace enrollment: The credit applies to qualifying coverage purchased through a Health Insurance Marketplace, not to any health plan chosen elsewhere.
- Household and tax circumstances: Filing status, dependents, and who is enrolled affect the determination. Use the Marketplace application and the IRS instructions for the relevant tax year rather than assuming that the number of people in your home alone defines the tax household.
- Income: The Marketplace asks for projected household income. The IRS’s general income framework for years outside the temporary 2021–2025 expansion is at least 100% and no more than 400% of the federal poverty line, subject to exceptions and detailed rules. The temporary removal of the 400% ceiling applied to tax years 2021 through 2025; it should not be assumed to apply to 2026.
- Other coverage: Eligibility can be affected if you are eligible for employer coverage that is affordable and meets minimum value, or for certain government coverage. The relevant rules are specific; do not decide based only on whether you currently use that coverage.
Because the poverty-line figures and rules are tax-year-specific, and plan costs vary by location, an income range found online cannot confirm an individual result. Apply through HealthCare.gov or your state’s Marketplace and review the result for your household and coverage year.
Premium tax credits and cost-sharing reductions are different
Both are forms of Marketplace savings, but they reduce different costs. Review the plan’s premium after any credit and its cost-sharing details separately when comparing coverage.
| Type of help | What it reduces | How to check |
|---|---|---|
| Premium tax credit (PTC) | The monthly premium for qualifying Marketplace coverage. It can be paid in advance to the insurer or claimed when filing. | Review your Marketplace eligibility result and the premium shown for each plan. |
| Cost-sharing reductions (CSRs) | Your share of costs for covered care, rather than the plan’s monthly premium. | Review the Marketplace result and plan details for the coverage available to you. |
After checking both kinds of savings, compare provider and prescription coverage and the costs you might face for the care you expect. A lower premium alone does not show whether a plan is the best fit.

HealthCare.gov says the additional savings that had been available through 2025 ended on December 31, 2025, and warns that people who qualify for 2026 savings will likely pay more for Marketplace premiums. This does not mean that all help ended: the ordinary premium tax credit remains available to people who qualify under the applicable rules. Use current Marketplace plan results rather than carrying forward a 2025 estimate.
There is also a tax-reconciliation change. The IRS says the limits on repayment of excess advance premium tax credits were removed for tax years beginning after December 31, 2025. For coverage in 2026, if advance payments are greater than the credit allowed using your final tax-year information, you may have more to repay than under the repayment-cap rules that applied in prior years. Keep the coverage year distinct from the filing year: 2026 coverage is reconciled on the tax return for tax year 2026, generally filed in 2027.
How to apply and keep your estimate accurate
- Apply through HealthCare.gov or your state Marketplace. Provide the household, projected-income, location, and coverage information the application requests.
- Read the full eligibility result. Check separately for a premium tax credit, cost-sharing reductions, Medicaid, or CHIP. Medicaid and CHIP may be the appropriate route for some households, depending on state rules and household circumstances.
- Choose how to use any estimated PTC. If offered an advance credit, decide how much to have sent to the insurer each month. Taking less than the estimated amount can reduce the chance that advance payments exceed the final allowed credit, but it also means paying more of the premium during the year.
- Update the application when circumstances change. Report changes in projected income, household size, address, or access to employer or government coverage promptly. An outdated estimate can leave you with too much or too little advance credit.
- Keep income records and Marketplace tax documents. Save Form 1095-A and records that help establish your actual tax-year circumstances.
How the credit is reconciled at tax time
If you received advance premium tax credit payments, use Form 1095-A to complete Form 8962 with your federal tax return. Form 8962 compares the advance payments made for your coverage with the PTC allowed based on your actual tax-year information. If the advance amount was lower than the allowed credit, the difference may increase your refund or reduce the amount you owe; if it was higher, the excess may affect your refund or tax due. For tax year 2026, the IRS says repayment caps no longer limit repayment of excess advance payments.
Failing to reconcile advance payments can affect eligibility for advance premium credits or cost-sharing reductions in a following year. Follow the IRS instructions for the tax year on which you are filing, since eligibility and repayment rules can change by year.
