ACA premium tax credits (PTCs) in 2026 are strictly income-gated. Because the enhanced premium tax credits from the American Rescue Plan Act (ARPA) and Inflation Reduction Act (IRA) expired on January 1, 2026, the 400% FPL subsidy cliff is fully back. For a single-person household in 2026, that cliff sits at $63,840. For a family of 4, it sits at $132,000. If your Modified Adjusted Gross Income (MAGI) moves above those lines mid-year, your Advance Premium Tax Credit (APTC) either drops sharply or disappears entirely, and your monthly Marketplace premium can jump hundreds of dollars overnight. Healthcare.gov reports income changes to your state exchange within 5 to 10 business days of the update. Your insurer then adjusts your monthly bill. The jump is jarring, and many enrollees land on this page within days of seeing a new, much higher premium bill or receiving a notice from their insurer that their APTC is being reduced.
Losing your ACA subsidy in 2026 does not mean you are stuck with an unaffordable bill. An income change is a qualifying life event under federal SEP rules per healthcare.gov, which means a 60-day window opens from the date of the income change. During that window, you can switch to a different Marketplace plan, add or remove dependents, or re-evaluate your full coverage picture. More importantly, if your income dropped rather than rose, you may now qualify for Medicaid year-round with no deadline. Understanding the ACA income limits and how they interact with your current household size is the first step. This guide covers the 6 decisive steps, the comparison table of your real options for 2026, and the five most common mistakes people make that cost thousands. Check the Medicaid income limits to confirm your Medicaid eligibility threshold, and review the ACA income limits to understand the 400% FPL subsidy cliff that applies to your 2026 plan year.
6 Steps to Get Coverage
Common Mistakes That Cost People Thousands
The most expensive errors people make after losing an ACA subsidy in 2026:
- Reporting full-year prior income instead of projected forward income. ACA subsidies use projected annual MAGI, not last year's tax return. If your income changed mid-year, report only what you expect to earn for the full 2026 calendar year.
- Missing the 60-day SEP window. Once the window closes, you must wait until the ACA Open Enrollment Period beginning November 1, 2026 for 2027 plans. Update your income on healthcare.gov immediately after the change.
- Defaulting to COBRA when a Marketplace plan is cheaper. If you only lost a Marketplace subsidy (no employer plan loss), COBRA does not apply. If you also lost employer coverage, compare COBRA against an unsubsidized Marketplace Bronze plan before electing.
- Not checking Medicaid first when income dropped. A mid-year income drop below 138% FPL in an expansion state qualifies you for free Medicaid year-round. Many people pay Marketplace premiums they no longer need to pay.
- Skipping 1095-A reconciliation. If you received advance premium tax credits in 2026 based on a projected income that turned out lower than actual, the IRS will recover the excess via Form 8962. Updating your income on healthcare.gov during the year reduces the end-of-year repayment shock.
- Assuming the ACA subsidy cliff extension still applies in 2026. Enhanced premium tax credits expired January 1, 2026. Any 2025 guidance saying the cliff is extended is outdated. For 2026, households above 400% FPL receive zero subsidy.
The 2026 Subsidy Cliff: What Changed and Who Is Affected
ACA Marketplace premium tax credits from 2021 through 2025 were temporarily enhanced under the American Rescue Plan Act (ARPA) and extended by the Inflation Reduction Act (IRA). Those enhancements removed the 400% FPL income ceiling on subsidy eligibility and made premiums as low as $0 for many middle-income households. Both enhancements expired January 1, 2026, restoring the original ACA subsidy structure. For 2026, the income ceiling for any premium tax credit is 400% of the Federal Poverty Level, equal to $63,840 for a single-person household and $132,000 for a family of 4 in the 48 contiguous states and DC (based on HHS ASPE 2026 Poverty Guidelines). Households with MAGI above those thresholds receive zero federal premium tax credit. The shift was immediate and affected approximately 5 million enrollees who had subsidies under the enhanced rules but cross the 400% cliff under the restored 2026 rules, according to KFF analysis of 2025-2026 enrollment transitions.
Mid-year income changes compound the cliff problem. An individual who starts 2026 at $55,000 annual income (below the $63,840 cliff) and receives a raise or takes a second job that pushes projected annual MAGI to $70,000 crosses the cliff mid-year. Healthcare.gov instructs all enrollees to report income changes promptly. When you update income above 400% FPL, the system terminates your APTC and your insurer raises your monthly premium to the full unsubsidized rate. The reporting obligation matters for another reason: if you do not report promptly and continue receiving APTC you no longer qualify for, the IRS will assess the full repayment on Form 8962 at tax time, with no cap for incomes over 400% FPL in 2026. The safest strategy is to report immediately, even though doing so eliminates your subsidy.
Medicaid Eligibility After an Income Drop in 2026
Medicaid is income-gated at 138% FPL in the 40 expansion states plus DC. A mid-year income drop that brings your household MAGI below that threshold qualifies you for Medicaid immediately, with no SEP window and no deadline. State Medicaid programs use different brand names: California calls it Medi-Cal; Arizona uses AHCCCS (the state's full program name); Wisconsin uses BadgerCare; Massachusetts uses MassHealth; Connecticut uses HUSKY Health; Oregon uses OHP (Oregon Health Plan); Washington uses Apple Health; Tennessee uses TennCare; Indiana uses HIP (Healthy Indiana Plan). Using your state's brand name in your search will get you to the right enrollment portal faster than searching generically for 'Medicaid.' If you live in one of the 10 non-expansion states (Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, Wyoming), the 138% FPL threshold does not apply to non-disabled adults, and a Medicaid pivot may not be available unless you qualify through another pathway such as pregnancy, disability, or age.
CHIP (Children's Health Insurance Program) remains available year-round for children in households that do not qualify for Medicaid but have income under the state CHIP income ceiling, typically 200% to 300% FPL depending on the state. If your adult household income increased above subsidy range but your children's household-size income calculation still falls within CHIP limits, they may enroll separately. All 50 states plus DC operate CHIP programs. Enrollment is year-round and co-pays are very low. Even when adults lose ACA subsidies and cannot afford full Marketplace premiums, children in the household almost always have a Medicaid or CHIP coverage path at no cost.

Documents You Will Need for the Income-Change SEP Application
Marketplace SEP applications for income changes require documentation verifying the change. Healthcare.gov may ask for proof within 30 days of enrollment. Having documents ready speeds up enrollment and prevents your coverage from being terminated post-enrollment for missing verification. The type of documentation depends on what caused the income change: a new job requires recent pay stubs or an offer letter showing salary; a job loss requires a termination letter or final pay stub; self-employment income changes require a profit-and-loss statement or bank statements. Social Security income changes require a benefit award letter from the SSA. If you are also enrolling dependents or removing them, birth certificates or divorce decrees may be required. The federal poverty level and ACA income limits pages explain how each income source is counted for MAGI, so you can build your income projection accurately.
- Recent pay stubs (last 2-3) showing current salary or hourly rate, or an employer offer letter confirming new compensation
- Termination or layoff letter from employer (if income dropped due to job loss)
- Unemployment award letter showing weekly benefit amount (unemployment counts as MAGI income for subsidy calculations)
- Self-employment profit-and-loss statement or 3-6 months of business bank statements
- Social Security benefit award letter (if Social Security income changed)
- Social Security numbers for all household members applying
- Prior 1095-A form (if reconciling prior-year APTC with the IRS via Form 8962)
Frequently Asked Questions
What is the SEP window after losing an ACA subsidy due to an income change in 2026?
An income change that affects your ACA premium tax credit eligibility is a qualifying life event that opens a 60-day Special Enrollment Period (SEP) under federal Marketplace rules per healthcare.gov. Your 60-day window starts on the date of the income change. For example, if your income changed on July 1, 2026, your SEP runs through August 30, 2026. During this window, you can switch plans, change metal tiers, or add or remove dependents. If your income dropped below 138% FPL, Medicaid enrollment is year-round with no deadline and no SEP required.
Did the ACA subsidy cliff return for 2026?
Yes. Enhanced premium tax credits introduced by the American Rescue Plan Act (ARPA) in 2021 and extended by the Inflation Reduction Act (IRA) through 2025 both expired January 1, 2026. The original 400% FPL income ceiling is fully restored for 2026 Marketplace coverage. Households with Modified Adjusted Gross Income (MAGI) above 400% FPL (above $63,840 for a single person or $132,000 for a family of 4 in the 48 contiguous states and DC) receive zero federal premium tax credit in 2026. Any guidance saying the cliff is extended or removed is outdated as of January 1, 2026.
How do I document an income change for the Marketplace SEP application?
Healthcare.gov requires evidence of the income change event within 30 days of enrollment under a Marketplace SEP. Acceptable documentation includes: recent pay stubs (typically the last 2-3) showing current salary for a new job or raise; a termination or layoff letter for a job loss; a self-employment profit-and-loss statement or recent business bank statements; or a Social Security benefit award letter if your Social Security income changed. Log in to healthcare.gov, select your qualifying life event as 'Change in household income,' and upload documents as prompted. Incomplete documentation can delay coverage or trigger post-enrollment verification that terminates coverage.
What if I miss the 60-day SEP after losing my subsidy?
Missing the 60-day SEP window for a Marketplace income change means you generally cannot make mid-year plan changes until the next ACA Open Enrollment Period, which for 2027 coverage begins November 1, 2026. Your current Marketplace plan continues at the unsubsidized premium. If your income later drops below 138% FPL in a Medicaid expansion state, Medicaid enrollment remains year-round regardless of missing the SEP. If another qualifying life event occurs (job loss, marriage, birth, move), a new 60-day window opens from that event's date.
Do I qualify for Medicaid if I lost my ACA subsidy because my income dropped?
Possibly, and it is the first thing to check. In the 40 Medicaid expansion states plus DC, any household with 2026 income under 138% FPL qualifies for Medicaid year-round with no deadline. For 2026, that means under $22,025 for a single person and under $45,540 for a family of 4 (HHS ASPE 2026 Poverty Guidelines). Medicaid enrollment is handled through healthcare.gov or your state Medicaid agency. State programs use different names: Medi-Cal (California), AHCCCS (Arizona), BadgerCare (Wisconsin), MassHealth (Massachusetts), HUSKY Health (Connecticut). If you qualify for Medicaid, you can disenroll from your Marketplace plan without a penalty. The 10 non-expansion states have much stricter income thresholds for non-disabled adults.
What happens to my 1095-A and IRS subsidy reconciliation after I lose my ACA subsidy?
Your Marketplace sends a Form 1095-A in January 2027 summarizing all advance premium tax credits (APTC) paid on your behalf during 2026. You reconcile those credits on IRS Form 8962 when you file your 2026 federal tax return. If your actual 2026 MAGI was higher than projected and you received more APTC than you were entitled to, you owe the excess back. For 2026, the IRS repayment cap was removed for households with income above 400% FPL (meaning full repayment is owed with no limit). For households under 400% FPL, repayment caps apply on a sliding scale. Updating your income estimate on healthcare.gov throughout the year when it changes is the best way to minimize the repayment amount.
What are the CHIP options for my children if I lose my adult ACA subsidy?
CHIP (Children's Health Insurance Program) covers children in households with income too high for Medicaid but below the state CHIP ceiling, typically 200% to 300% FPL depending on the state. CHIP enrollment is year-round with no deadline, and premiums are very low or free. Even when your adult income is above the ACA subsidy range (above 400% FPL in 2026), your children may still qualify for CHIP based on household size and income. All 50 states and DC operate CHIP programs. Apply through healthcare.gov or your state Medicaid/CHIP agency. Some states have brand names for their CHIP programs (AllKids in Illinois, HUSKY Health in Connecticut, NJ FamilyCare in New Jersey, PA CHIP in Pennsylvania).
Is COBRA an option if I only lost an ACA Marketplace subsidy (not employer coverage)?
No. COBRA continuation coverage applies only to people who had employer-sponsored group health insurance and then lost that coverage due to a qualifying event. COBRA does not apply to ACA Marketplace plans purchased individually. If you had only a Marketplace plan and lost your subsidy, your options are to pay the full unsubsidized Marketplace premium, switch to a different Marketplace plan during your 60-day SEP window, enroll in Medicaid if eligible, or enroll in CHIP for children. COBRA becomes relevant only if you simultaneously lose employer-sponsored coverage along with losing your Marketplace subsidy, which would be a separate triggering event.
