COBRA versus a Marketplace plan: when PTC is available

Learn when a COBRA offer leaves the Marketplace premium tax credit available and when actual COBRA enrollment blocks it.

Ruling
For 2026, merely being offered COBRA after employment ends does not make a former employee eligible for employer coverage for PTC purposes. The affected person is treated as eligible for COBRA only for months actually enrolled in it.

Separate the offer from enrollment

Post-employment COBRA follows a narrower PTC rule than an active employee's offer. A person who declines COBRA may qualify for PTC on a Marketplace plan if the income, filing, Marketplace-enrollment, and other coverage tests are met. A person enrolled in COBRA has employer-sponsored minimum essential coverage for those months and cannot also claim PTC for their own Marketplace coverage.

Protect the enrollment window

Losing job-based coverage generally opens a Marketplace Special Enrollment Period, but the Marketplace and COBRA election clocks are separate. Ending COBRA early by choice does not necessarily create another opportunity to enroll. Compare effective dates before electing either option, and include all income earned earlier in the calendar year when the Marketplace estimates savings.

Decision example and common errors

A worker's group plan ends in April. The worker declines COBRA and enrolls in a Marketplace plan effective in May, so May can be a PTC month if every other condition is satisfied. Electing COBRA for May and also taking APTC for May would create overlapping coverage. Another error is missing the Marketplace enrollment period while assuming COBRA can be dropped at any time.

Choose coverage before the deadlines diverge

Compare COBRA and Marketplace coverage using effective dates, full-year household income, net premiums, cost sharing, provider access, and the PTC treatment of actual enrollment. A COBRA offer after employment ends is not itself disqualifying, but an elected COBRA month is employer-sponsored coverage. Preserve the election notice and Marketplace eligibility result.

Revisit the choice if another employer or spouse offer appears, because active-employee affordability rules differ from the post-employment COBRA rule.

Dates to verify before choosing COBRA

  • Record the final active-employee coverage date.
  • Confirm the Marketplace Special Enrollment Period deadline.
  • Prevent COBRA and APTC from overlapping for the same person and month.
