The Advance Premium Tax Credit (APTC) is a federal tax credit that reduces the monthly cost of ACA Marketplace health insurance for households with income between 100% and 400% of the Federal Poverty Level. Under the American Rescue Plan Act (ARP) and its extensions, households above 400% FPL may also qualify if their benchmark plan premium would otherwise exceed 8.5% of their income. The credit is paid directly to your insurer; you pay only the remaining balance.

How is my APTC amount determined?

The IRS uses the premium of the second-lowest-cost Silver plan in your county as a benchmark. Your required contribution is a percentage of your income (ranging from 0% at 100% FPL to 8.5% at 400%+ FPL). APTC equals the benchmark premium minus your required contribution. The dollar amount is fixed regardless of which plan you select.

What income qualifies for APTC in 2026?

For a single individual, income between $15,060 (100% FPL) and approximately $60,240 (400% FPL) typically qualifies. For a family of four, the range is $31,200 to $124,800. Under current ARP extension rules, households above 400% FPL may also qualify if their required premium would exceed 8.5% of income.

What is the difference between APTC and CSR?

APTC reduces your monthly premium and applies to any metal tier plan. CSR (Cost-Sharing Reduction) reduces what you pay when you use healthcare — deductibles, copays, coinsurance, and out-of-pocket maximums. CSR is available only on Silver plans for households between 100% and 250% FPL.

Can I use APTC on a Bronze or Gold plan?

Yes. APTC can be applied to Bronze, Silver, Gold, or Platinum plans from any ACA Marketplace insurer in your area. CSR, however, is only available on Silver plans.

What happens if my income changes after I enroll?

Report income changes to your Marketplace as soon as they occur. If your income rises, your APTC may decrease — and receiving too much APTC during the year means you repay the excess when you file Form 8962. If your income decreases, you may be owed additional credit as a tax refund.

What if I overestimated my income when applying?

If your actual income is lower than estimated, you received less APTC than you were entitled to. The IRS will calculate the difference when you file and issue a credit or refund. There is no penalty for underestimating in this direction.

Can I get APTC if my employer offers health insurance?

Only if your employer's coverage is deemed unaffordable or inadequate by ACA standards. Coverage is considered unaffordable if the employee-only premium exceeds 9.02% of household income (2026 threshold). If employer coverage is affordable and meets minimum value, you cannot claim APTC for Marketplace coverage.

Does Medicaid eligibility affect APTC?

Yes. Medicaid-eligible individuals are not eligible for APTC. Medicaid eligibility is determined separately by each state based on income and other factors. If you qualify for Medicaid, you must enroll in Medicaid — you cannot decline Medicaid to receive APTC instead.

Is this calculator an official government tool?

No. This calculator uses official CMS Marketplace API data to estimate APTC based on your inputs. Results are estimates only. Official APTC determinations are made by your state Marketplace or HealthCare.gov during enrollment. Policymage is not affiliated with any government agency.
