PiggyPTC repayment uncapped in 2026 Tax year 2026
Form 8962 still reconciles advance Marketplace credits — but the under-400% repayment ceiling that soft-landed honest misses is gone.
Finding: Many ACA / PTC tools still apply the old Form 8962 Table 5 repayment caps (through 2025: up to $1,625 single / $3,250 other under 400% FPL). For tax years after 2025 the IRS says there is no repayment cap — you repay the full excess advance credit. In the household-of-two case below ($35k estimated → $82k actual, $1,450/mo benchmark), a capped tool shows $1,625 while uncapped Form 8962 math is about $6,439 (~$4,800 understated). The same advance credit against a $91k cliff crossing is about $15,672 — a stale $1,625 display misses by roughly $14,000. Educational prep only — PiggyMath does not e-file and this is not tax advice.
The wrong rule vs the right rule
Wrong (common / stale): take excess advance PTC, then apply Form 8962 Table 5 — e.g. min(excess, $1,625) for a single filer between 300% and 400% of FPL — as if 2025 rules still apply.
Right (tax years after 2025): recompute allowable PTC on actual household income (benchmark silver − required contribution, zero above 400% FPL), subtract from advance payments received, and repay the full difference. The IRS Q&A on the Premium Tax Credit states there is no repayment cap for tax years after 2025. See also Instructions for Form 8962 and Publication 974.
Still true either year: at 400% FPL or above there was never a Table 5 cap — the whole excess was always repayable. What OBBBA removed is the under-400% safety net. The 400% cliff also returned for 2026 coverage after enhanced subsidies expired.

|---|---|---|---|
| Income told to Marketplace | $35,000 (~166% FPL) | — | |

What actually changed
Through tax year 2025, if you received more advance premium tax credit than Form 8962 allowed — and your household income stayed under 400% of the federal poverty line — repayment could be limited by statute (Table 5). That existed because Marketplace income estimates are guesses, especially for freelancers.
For tax years beginning after December 31, 2025, the IRS Q&A states there is no repayment cap: the full excess is added to tax (Schedule 2). The 400% cliff for eligibility also returned for 2026 coverage when temporary enhanced credits expired — so a dollar over the line can zero the whole year’s credit.
Who is affected / who is not
Affected: anyone who took advance PTC in 2026 and finished with higher MAGI than the Marketplace used — especially self-employed people with lumpy Q4 income. Stale software that still shows Table 5 will understate the April bill.
Not a new cliff-above-400% rule: repayment at or above 400% FPL was already uncapped. What is new is the disappearance of the under-400% cushion in Figure 1.
Still protected in a bad year (separate rule): if actual income falls below 100% FPL but the Marketplace correctly estimated you at or above 100% when it paid APTC, Form 8962 instructions can still treat you as an applicable taxpayer — see the live calculator’s “rule that works in your favour” note.
Same “most tools stop on the old rule” pattern: Solo 401(k) 20% vs 25%, S-Corp payroll vs lost QBI, and Form 2210 annualized method.
