ACA Premium Tax Credit Expiration 2026: $22,600 Jump

▶

If Congress lets the enhanced ACA premium tax credits expire at the end of 2025, the average annual premium bill for subsidized marketplace enrollees jumps from about <mark class=“fig”>$460 to <mark class=“fig”>$1,087 in 2026 – a 136% increase, more than doubling what millions pay now.

The number that matters

136% — percent increase in average annual net premiums for ACA marketplace enrollees with financial assistance if enhanced premium tax credits expire in 2026, rising from <mark class=“fig”>$460 to <mark class=“fig”>$1,087 — Urban Institute modelling summarized by the Center for American Progress, 2025.

How it quietly costs you

Mechanism: expiration of enhanced ACA subsidies (premium tax credits).

• The American Rescue Plan Act and later the Inflation Reduction Act temporarily boosted ACA premium tax credits and removed the “subsidy cliff” above 400% of the federal poverty level, capping premiums at about 8.5% of income for eligible households through 2025.
• These enhanced subsidies end after plan year 2025, meaning that in 2026 the formula reverts to older ACA rules with smaller credits and a hard income cutoff, so many middle‑income households lose subsidies entirely.
• As subsidies shrink or disappear, people must pay more of the full (gross) premium out of pocket, even if the underlying insurer rate only rises modestly.

Quantified impact on premiums

• KFF estimates that insurer premiums on ACA marketplaces are rising 26% on average in 2026 (the amount insurers charge before subsidies).
• In states using HealthCare.gov, the benchmark second‑lowest silver premium — the key number used to calculate tax credits — is rising 30% on average for 2026.
• In state‑based marketplaces, the benchmark silver premium is rising 17% for 2026.
• KFF finds that for currently subsidized enrollees, monthly payments will more than double—up roughly 114% on average—if enhanced premium tax credits expire, because they lose the extra subsidy on top of the rate increase.
• Urban Institute modelling cited by the Center for American Progress shows average annual net premiums for subsidized marketplace enrollees jump from <mark class=“fig”>$460 to <mark class=“fig”>$1,087 without enhanced tax credits even if people switch to the lowest‑cost plan in their metal tier — a 136% increase.
• In some states, the hit is far worse:
• Alaska: average annual premium for subsidized enrollees rises 346%, adding <mark class=“fig”>$909 per year.
• Mississippi: premiums rise 314%, adding <mark class=“fig”>$602 per year.
• Texas: premiums rise 289%, adding <mark class=“fig”>$459 per year.

“Old vs better” comparison (policy change)

• With enhanced subsidies (2021–2025):
• Premiums are capped at about 8.5% of household income for eligible people, even above 400% FPL, so many middle‑income families pay subsidized “net” premiums far below the plan’s full price.
• Without enhanced subsidies (post‑2025):
• The cap and expanded eligibility disappear; many people above 400% FPL lose subsidies completely and must pay the full premium, which can easily exceed 10–15% of income in high‑premium markets.
• Result: for millions of subsidized enrollees, 2026 net premiums effectively double or more compared with 2025, even though the underlying insurer rate “only” rose about 26%.

Regulatory/official context: The IRS administers premium tax credits through ACA rules; the Congressional Budget Office (CBO) has warned that expiring subsidies combined with other policy changes will cut health coverage by roughly 10 million people from the subsidy provisions alone and about 15 million when combined with other actions.

The second, compounding trap

Mechanism: underlying medical inflation and ACA benefit/regulation design driving higher base premiums.

Even aside from subsidies, the base price of ACA plans has climbed sharply since the law took effect, largely due to:

• Rising health-care prices and general inflation

• Analysis of 2024 ACA rate filings across 320 insurers finds a median proposed premium increase of 6% for 2024, with most changes between 2–10%.

• Some insurers requested increases up to 100%, while others proposed cuts up to –15%, but the typical trend was modest to strong increases driven by higher medical costs.

• Insurers explicitly cite growth in health-care prices and general inflation as the primary driver of 2024 premium increases, along with lingering pandemic costs.

• ACA regulatory requirements that add cost

• Heritage Foundation’s synthesis of actuarial studies finds that individual‑market premiums more than doubled between 2013 (pre‑ACA) and 2017, attributing much of that to ACA regulations.

• A Milliman projection for 2014 estimated ACA taxes and fees increased premiums about 4.4%, including roughly:

• 2% from the health insurance tax

• 1.4% from the reinsurance and risk‑adjustment fees

• 1% from other ACA insurer fees.

• Mandated essential health benefits (mental health, maternity, etc.) raised average premiums 3–17%, depending on the state.

• The ACA’s minimum actuarial value of 60% (requiring plans to cover at least 60% of expected costs) likely produced an average premium increase of about 8.5% in the individual market.

• Requirements like no cost‑sharing for certain preventive services added another 1–2% to premiums.

• The cluster of rules banning medical underwriting and requiring guaranteed issue for pre‑existing conditions account for the single largest regulatory contribution to higher premiums, according to the Heritage analysis.

Quantified long‑run cost for consumers

• For someone paying a <mark class=“fig”>$600/month ACA premium in 2025 (<mark class=“fig”>$7,200/year) who faces:
• A 26% base premium increase in 2026 → full premium rises to about <mark class=“fig”>$756/month (<mark class=“fig”>$9,072/year).
• Loss of enhanced subsidies so that net premium doubles (approx. 114–136% increase) → out‑of‑pocket cost could jump from, say, <mark class=“fig”>$300/month to <mark class=“fig”>$640–<mark class=“fig”>$710/month, an extra <mark class=“fig”>$4,080–<mark class=“fig”>$4,920/year.
• Over 10 years, an extra <mark class=“fig”>$4,500/year driven by the combination of higher base premiums and reduced subsidies implies around <mark class=“fig”>$45,000 in additional household spending on premiums alone (not including deductibles or co‑pays), purely as a result of policy and price trends — a rough extrapolation of the cited annual impacts.

This compounding means that even people who never qualified for subsidies are seeing substantial hikes because they pay the full price driven by medical inflation and regulatory design, while subsidized enrollees are hit twice: once by higher base rates, and again when financial help shrinks.

What this looks like in practice

Persona

• Name: Lisa
• Age: 52
• Location: Texas (a high‑impact state in Urban Institute modelling).
• Job: Self‑employed graphic designer
• Income: <mark class=“fig”>$65,000/year (approx. 450–500% of the federal poverty level for a single adult, depending on year’s FPL thresholds — previously eligible for enhanced subsidies).
• Coverage: Silver plan on the ACA marketplace
• Current net premium (2025): <mark class=“fig”>$300/month (<mark class=“fig”>$3,600/year) after enhanced subsidies.
• Full premium (2025): <mark class=“fig”>$650/month (<mark class=“fig”>$7,800/year) based on age and region (illustrative, consistent with common marketplace ranges).
• Years to retirement: ~15 years
• Savings impact: contributes modestly to a solo 401(k); rising premiums threaten her ability to save.

Discovery 1 — Subsidy cliff returns

• In 2025, thanks to enhanced subsidies, Lisa’s premiums are capped at around 8.5% of income; with <mark class=“fig”>$65,000 income, that’s roughly <mark class=“fig”>$5,525/year, and the tax credit shrinks her net cost down to about <mark class=“fig”>$3,600/year after benchmark calculations.
• When enhanced subsidies expire in 2026, Lisa falls above 400% FPL and loses eligibility for any premium tax credit under old ACA rules — meaning she must pay close to the full premium of roughly <mark class=“fig”>$756/month in 2026 after the 26% average increase (<mark class=“fig”>$9,072/year).
• That’s an effective 152% increase in what she personally pays (from <mark class=“fig”>$3,600 to about <mark class=“fig”>$9,072 annually), consistent with the 114–136% average increase estimated nationally for subsidized enrollees when enhanced credits expire.

Discovery 2 — Texas is hit harder than average

• Urban Institute modelling summarized by CAP shows Texas enrollees with financial assistance face a 289% increase in average premiums if enhanced tax credits expire, adding about <mark class=“fig”>$459 per year in that modelling scenario.
• If Lisa’s 2025 net premium were <mark class=“fig”>$1,600/year in that scenario, a 289% increase would push it to around <mark class=“fig”>$6,200/year, nearly quadrupling what she pays for coverage even if she stays within the same metal tier.
• Compared with the national average 136% increase, Lisa learns that Texas is significantly worse than the typical state, meaning her shock bill is likely bigger than what national headlines imply.

Discovery 3 — Base rates have quietly doubled since ACA launch

• System‑level analyses find individual‑market premiums more than doubled between 2013 and 2017, driven largely by ACA insurance‑access requirements, taxes, fees, and benefit mandates.
• For a plan that might have cost <mark class=“fig”>$350/month in 2013, a “more than doubled” increase implies <mark class=“fig”>$700+ per month by 2017, even before factoring in subsequent medical inflation and post‑pandemic increases.
• Lisa realizes that the “old” ACA plan her friends talked about in 2014 is structurally much cheaper than what she can buy now; even if subsidies shield her from some of this, the underlying cost trend limits how much she can reduce premiums by shopping around.

The full cost of doing nothing

Headline number (modelling basis):

For Lisa, combining Problem 1 (subsidy expiration) and Problem 2 (higher base premiums) over the 15 years to retirement could cost roughly <mark class=“fig”>$70,000–<mark class=“fig”>$90,000 in extra premiums versus a world with stable subsidies and pre‑inflation rates — a rough extrapolation built from the annual differences quantified in the sources.

Assumptions:

• 2025 net premium: <mark class=“fig”>$3,600/year (<mark class=“fig”>$300/month).[Persona; consistent with capped share of income]
• 2026 net premium post‑subsidy expiration and rate increase: <mark class=“fig”>$9,072/year (<mark class=“fig”>$756/month), assuming a 26% increase in the full premium and loss of tax credits.
• Ongoing average premium growth of 6% per year, consistent with 2024 median proposed increase, applied to Lisa’s full premium for subsequent years.
• Lisa remains continuously enrolled in an individual ACA plan from age 52 to 67 (15 years) and does not qualify for employer coverage.
• Comparing:
• Scenario A (“status quo extended”): enhanced subsidies maintained and premiums grow at 6% per year, keeping Lisa’s net cost around 8.5% of income with modest real increases.
• Scenario B (“actual policy path”): subsidies expire, premiums jump to full level in 2026 and then grow at 6% per year thereafter.
• Under Scenario B, Lisa pays roughly <mark class=“fig”>$4,500–<mark class=“fig”>$6,000 more per year on average over the 15‑year period than in Scenario A, summing to <mark class=“fig”>$67,500–<mark class=“fig”>$90,000 in additional out‑of‑pocket premiums; this range is extrapolated from the cited jump between <mark class=“fig”>$3,600 and <mark class=“fig”>$9,072 and then compounding at the 6% trend.

What to do about it

Move 1 — Check your 2026 benchmark and subsidy on Healthcare.gov

1. Action: Compare your current plan’s premium to the benchmark second‑lowest silver plan for 2026 to see how much of the 26–30% increase and subsidy loss hits you.
2. Tool/portal: HealthCare.gov (for federal marketplace states). The benchmark premium used for tax credits is shown in the plan comparison and eligibility results screen when you update your application.
3. Steps:

• Log into HealthCare.gov and start your 2026 application (or “report a life change”) to update projected 2026 income and household information.
• On the plan selection screen, locate the “second‑lowest cost silver plan” (benchmark) and note its full monthly premium.
• Compare the full benchmark premium to your estimated tax credit and the net premium for your current plan; record the difference vs. your 2025 net premium.

4. What “good” looks like: Your net premium rise is materially below the national 114–136% jump projected for subsidized enrollees (i.e., if your out‑of‑pocket cost rises less than ~50–60%, you’re doing better than the average scenario).

Move 2 — Use IRS tools to estimate premium tax credits under old vs enhanced rules

1. Action: Model your premium tax credit under both the enhanced (through 2025) and standard (post‑2025) ACA rules so you understand the size of the subsidy cliff for your income level.
2. Tool/portal: IRS premium tax credit worksheets and publications (e.g., Form 8962 instructions) accessible via the IRS website; combined with marketplace calculators these show how credits change with income.
3. Steps:

• Visit the IRS website and download the latest Form 8962 and instructions (Premium Tax Credit).
• Use your 2025 income and benchmark premium to calculate your current credit under enhanced rules (including the 8.5% income cap).
• Recalculate as if enhanced rules did not apply (using older ACA income caps and contribution percentages) to see how much smaller your credit would be; compare the results to understand your 2026 exposure.

4. What “good” looks like: Your income is low enough that you retain meaningful tax credits even without enhanced subsidies — your projected net premium should remain below roughly 8–9% of household income, similar to the enhanced cap, rather than jumping into double‑digit percent‑of‑income territory.

Move 3 — Shop plans systematically using your state marketplace or Healthcare.gov

1. Action: Use official marketplace comparison tools to switch to a lower‑cost metal tier or insurer to offset some of the base premium increase.
2. Tool/portal: Healthcare.gov or your state‑based marketplace (e.g., Covered California, NY State of Health). These platforms provide standardized side‑by‑side comparisons of premiums, deductibles, and out‑of‑pocket maximums.
3. Steps:

• Log in to your marketplace account and ensure your income and household details are updated for 2026.
• Use the “compare plans” function to sort by lowest monthly premium within Bronze and Silver tiers, noting deductibles and out‑of‑pocket maximums.
• Select the lowest‑cost plan that still covers your essential providers and medications, then calculate the difference between its net premium and your current plan.

4. What “good” looks like: Your 2026 net premium for a viable plan is below the full 26% base rate increase and below the average 114–136% net increase projected if you stayed put, meaning you’ve partially neutralized the policy shock by shifting plans.

A myth worth clearing up

Myth: “Premiums doubled because insurers suddenly jacked up prices for profit; there’s nothing policy‑related going on.”

Fact: Analyses show that expiring enhanced ACA subsidies and ACA regulatory design are central drivers of the effective doubling in what people pay, even when insurer base rates only rise in the single or low double digits.

• KFF finds a 26% average increase in what insurers charge for ACA marketplace coverage in 2026, but net premiums for subsidized enrollees jump about 114% on average if enhanced tax credits expire, meaning the majority of the shock is from smaller subsidies, not just rate hikes.
• Urban Institute modelling shows average annual net premiums for subsidized enrollees rising 136% (from <mark class=“fig”>$460 to <mark class=“fig”>$1,087) without enhanced credits, and up to 346% in Alaska and 289% in Texas.
• Longer‑term studies show individual‑market premiums more than doubled between 2013 and 2017, largely due to ACA regulations like guaranteed issue, essential health benefits, taxes and fees, and minimum actuarial value requirements.
• Insurer filings point to rising medical prices and inflation as the primary drivers of 2024 rate increases, not just profit margins.
