Premium Tax Credit Guide 2026

What Changed for the Premium Tax Credit January 1, 2026

The American Rescue Plan Act (ARPA, P.L. 117-2, enacted March 2021) and the Inflation Reduction Act (IRA, P.L. 117-169, enacted August 2022) enhanced the premium tax credit in three ways through plan year 2025: lowered every applicable percentage in the IRC §36B(b)(3)(A)(i) table (top band fell from 9.5 percent to 8.5 percent), eliminated the 400 percent FPL eligibility cliff, and zeroed out the floor band so that households below 150 percent FPL paid nothing for benchmark coverage. These provisions sunset December 31, 2025.

For 2026 plan-year coverage, §36B reverts to its original ACA structure as inflation-adjusted by Rev. Proc. 2025-25. Three things happen simultaneously on January 1, 2026:

1. The 400 percent FPL cliff returns. Households above 400 percent FPL receive zero PTC. Earning even one dollar above the cliff eliminates the entire subsidy.
2. The applicable percentage table is higher. The 2026 top band (300-400 percent FPL) is 9.96 percent, up from 8.5 percent in 2025. Every band above 150 percent FPL is higher.
3. The floor band is reinstated. Households below 133 percent FPL pay 2.10 percent of MAGI for the benchmark plan, where they paid 0 percent under ARPA / IRA.

The combined effect is large. KFF's 2025 analysis projected that average premium payments for subsidized enrollees roughly doubled in 2026 versus 2025 for the same plan, driven both by the underlying premium increases and by the smaller PTC. Households that were comfortable on subsidized Marketplace coverage in 2025 may find 2026 coverage substantially more expensive, with some near the 400 percent FPL line losing PTC entirely.

The 2026 PTC Formula

The PTC for any taxable year is the lesser of (1) the premiums for the qualified health plan(s) the taxpayer is enrolled in through the Marketplace, or (2) the excess of the SLCSP benchmark premium over the taxpayer's required contribution. Stated as a formula:

Each input has a specific source:

• Actual plan premium = Form 1095-A Part III column A. The total premium of the plan you enrolled in, regardless of metal tier.
• SLCSP = Form 1095-A Part III column B. The second-lowest-cost silver plan available in your area on each enrollment day. Looked up at healthcare.gov/tax-tool by ZIP and family composition for prospective enrollment.
• Household MAGI = AGI + tax-exempt interest + nontaxable SS + foreign earned income excluded under §911. Aggregated across taxpayer + spouse (MFJ) + filing dependents.
• Applicable percentage = Rev. Proc. 2025-25 Table 2 lookup based on household income as percent of FPL.

The PTC is computed annually on Form 8962. If you received advance PTC during the year, you reconcile against the actual PTC and either receive the difference as a refundable credit or repay the excess.

The 2026 Applicable Percentage Table

Rev. Proc. 2025-25 Table 2 sets the 2026 applicable percentage as a function of household income expressed as a percentage of the federal poverty level. Within each band, the applicable percentage interpolates linearly between the band endpoints.

The 9.96 percent figure is also the 2026 affordability percentage for employer-sponsored coverage under §4980H(b) safe harbors. Both numbers move together by statutory design, indexed annually under §36B(b)(3)(A)(ii) to track health-cost growth.

The 2026 Cliff Numbers (48 States + DC)

The cliff is computed on the 2025 HHS poverty guidelines because §36B(d)(3)(B) requires the calculation to use the most recently published poverty guidelines as of the first day of the regular enrollment period for plan-year coverage. Open enrollment for 2026 plan-year coverage opened November 1, 2025; the most recently published guidelines on that date were the 2025 HHS guidelines.

Alaska and Hawaii use higher HHS tables: 2025 Alaska 100 percent FPL is 19,550 (single) + 6,870 per additional person; Hawaii is 17,990 + 6,320. The 400 percent multiplier applies the same way.

How Household MAGI Is Computed

MAGI for the premium tax credit under §36B(d)(2)(B) is a narrow definition that differs from MAGI used for IRA contributions, Roth eligibility, and other purposes. Start with AGI from Form 1040 line 11 and add three items:

1. Tax-exempt interest (Form 1040 line 2a). Municipal bond interest, qualified savings bond interest, and similar.
2. Nontaxable Social Security benefits (Form 1040 line 6a minus line 6b). The portion of SS benefits not included in taxable income because of the §86 inclusion limits.
3. Foreign earned income excluded under §911 (Form 2555).

Household MAGI then equals the taxpayer's MAGI plus the spouse's MAGI on a joint return, plus the MAGI of any dependent who is required to file a return. Dependents who file solely to claim a refund of withheld income tax do not have to be aggregated. The household composition is locked at the time of Marketplace enrollment but can be updated throughout the year for life events (marriage, divorce, birth, adoption, dependent change).

Common items that surprise taxpayers because they do not show up in regular take-home pay but do count for PTC MAGI: capital gains (taxable interest from a CD that matured, a rental sale, a stock sale), traditional IRA / 401(k) distributions, Roth IRA conversions, taxable Social Security, and Schedule C net profit. Items that are excluded from MAGI because they are excluded from AGI: HSA contributions (above-the-line deduction), traditional IRA / 401(k) / SEP / Solo 401(k) contributions (above-the-line if eligible), and student-loan-interest deduction.

SLCSP: The Second-Lowest-Cost Silver Plan

The SLCSP is the statutory benchmark plan under §36B(b)(2)(A). It is defined as the second-cheapest silver-tier plan available to your tax family in your rating area on each enrollment day. The PTC is computed off the SLCSP - the actual plan you choose to enroll in does not affect the PTC amount.

How to Look Up Your SLCSP

Three methods, in priority order:

• Form 1095-A Part III column B for past plan years. Issued by your Marketplace in January, covering each month of enrollment.
• healthcare.gov tax tool for prior plan years if you lost your 1095-A or for prospective planning. Enter ZIP code, household composition, and ages. Returns the SLCSP for each month of the year.
• State-based exchange tax tools for residents of state-run Marketplaces (CA, CO, CT, DC, ID, KY, MA, MD, ME, MN, NJ, NM, NV, NY, PA, RI, VT, WA). Each state runs its own equivalent tool.

Why Bronze + Big PTC Often Wins

Because PTC is fixed by SLCSP regardless of the plan you enroll in, low-income households frequently can enroll in a bronze plan with zero monthly out-of-pocket premium. Example: SLCSP for your household is 9,600 dollars annual. PTC is 4,145 dollars annual. If a bronze plan in your area costs 4,200 dollars annual (lower-tier plans are typically cheaper than silver), you pay 55 dollars per year out of pocket - effectively zero monthly premium - in exchange for a higher deductible. The bronze + big PTC combination is the standard low-cost path for healthy households at moderate FPL bands.

Cost-sharing reductions (CSRs) only apply to silver-tier plans for households 100 to 250 percent FPL, so households in that range often prefer silver to capture the lower deductibles and copays.

Form 8962 Reconciliation Mechanics

Form 8962 is the annual reconciliation of advance PTC against actual PTC. It must be filed with Form 1040 if either (1) the household received advance PTC during the year, or (2) the household enrolled in Marketplace coverage and is claiming PTC at year-end without having taken advance.

The form has four parts:

• Part I: Compute household income, family size, percent of FPL, and the applicable percentage. Identifies cliff status.
• Part II: Monthly PTC computation using Form 1095-A column A (premium), column B (SLCSP), and column C (advance PTC). Sums to annual PTC.
• Part III: Repayment of excess APTC. Applies the sliding-scale cap under §36B(f)(2)(B) for households below 400 percent FPL; uncapped at or above 400 percent FPL.
• Part IV-V: Allocation between tax families if needed (e.g., divorce mid-year, dependent claiming) and alternative calculation for marriage in the year.

If actual PTC exceeds advance PTC, the difference flows to Form 1040 line 31 as a refundable credit. If APTC exceeds actual PTC, the excess flows to Schedule 2 line 2 as an additional tax. The IRS will reject electronic returns that received APTC without an accompanying Form 8962, and failing to file Form 8962 in a year you received APTC will block future advance PTC and may stall the next year's refund.

The Cliff-Avoidance Playbook

For households between 380 and 410 percent FPL, the 2026 cliff dominates planning. A single dollar of MAGI above the cliff converts the entire annual PTC into a repayable amount, often 5,000 to 15,000 dollars per household. Practitioners should run a December cliff check on every APTC client in this band.

Above-the-Line MAGI Drops Available Through April 15

Each item is an above-the-line deduction that reduces AGI and therefore reduces MAGI for PTC. Listed in order of typical usefulness:

• Traditional IRA contribution. Up to $7,000 (under 50) or $8,000 (age 50+) for 2026. Deadline April 15, 2027 for the 2026 tax year. Deductible if covered by workplace plan and AGI under the phase-out, or fully deductible if not covered.
• HSA contribution. Up to $4,400 self-only or $8,750 family for 2026 (Rev. Proc. 2025-19), plus $1,000 age-55 catch-up. Requires HDHP coverage. Deadline April 15, 2027.
• Self-employed retirement plans. SEP-IRA up to 25% of net SE earnings, Solo 401(k) up to $24,500 elective + 25% employer, defined-benefit plans up to actuarial limits. Deadline October 15, 2027 with extension for SEP / Solo 401(k); extended deadlines do not apply to all plan types.
• Student loan interest deduction. Up to $2,500. Smaller but every dollar counts when near the cliff.

Within-the-Year Moves

Before December 31, taxpayers can also reduce 2026 MAGI through:

• Defer December bonus to January.
• Defer Roth conversion to next year.
• Accelerate deductible business expenses for Schedule C filers.
• Skip discretionary capital gain harvesting.
• Increase 401(k) elective deferrals through year-end paychecks (deadline December 31).

The Math of a Cliff Rescue

Every $1,000 of MAGI you move below the cliff can rescue the entire annual PTC. For a household at 405 percent FPL with a 6,000-dollar APTC, a $1,000 traditional IRA contribution that drops MAGI to 399 percent FPL rescues the full $6,000 - a 600 percent return on the contribution before considering the ordinary income tax savings. Few other tax moves have this risk-adjusted return profile. The catch is that every dollar must net to MAGI - a Roth IRA contribution does not work because Roth contributions are not deductible.

State-Based Exchange Subsidies (CA, NJ, NY, MA, VT, WA)

Six states layer state-funded subsidies on top of federal PTC through their state-based exchanges. State subsidies are funded outside the federal budget and continue regardless of the federal cliff. Eligibility levels and subsidy amounts vary by state and by year:

• California (Covered California). State subsidy can extend coverage above 400 percent FPL even after the federal cliff returned. Income-tested through Covered California's enrollment portal.
• New Jersey (NJ Health Plan Savings). State PTC supplement available for households up to 600 percent FPL.
• New York (Essential Plan + state subsidy). Essential Plan covers households 138 to 250 percent FPL with very low or no premium; state PTC supplement available beyond.
• Massachusetts (ConnectorCare). Subsidized program for households up to 500 percent FPL through the MA Health Connector.
• Vermont (Vermont Premium Assistance). State subsidy for households up to 300 percent FPL.
• Washington (Cascade Care + Cascade Care Savings). State public-option plans plus state-funded premium reduction for eligible households.

State subsidies are typically delivered as advance premium reductions through the state Marketplace at enrollment. Form 8962 still computes federal PTC only; state subsidies are reconciled separately on the state income tax return where applicable. Verify current eligibility on your state Marketplace's website during open enrollment.

Reporting and Documentation

Three documents drive PTC reporting:

• Form 1095-A (Health Insurance Marketplace Statement). Issued by your Marketplace by January 31. Reports monthly enrollment premium (column A), SLCSP benchmark (column B), and advance PTC paid (column C). Required to complete Form 8962. Retain for at least three years.
• Form 8962 (Premium Tax Credit). Annual reconciliation. Filed with Form 1040.
• Form 1095-B / 1095-C. Reports minimum essential coverage from non-Marketplace sources (employer, Medicaid, Medicare). Used to confirm employer affordability under §36B(c)(2)(C) and to coordinate Marketplace coverage with other coverage.

For taxpayers receiving APTC, the IRS auto-flags returns missing Form 8962 and pauses processing. Common practitioner errors: filing without Form 8962 when 1095-A was issued, mismatching family size between Marketplace and tax return, MAGI mistakes (forgetting tax-exempt interest), and using the wrong SLCSP after a mid-year coverage change. The Marketplace allocations on Form 1095-A are authoritative for monthly amounts; if you believe a column is wrong, correct it through the Marketplace before filing.
