A Florida small business that newly offers a group health plan triggers a significant change for employees who were buying individual ACA marketplace coverage. The new group offer creates a Special Enrollment Period (SEP) for employees to drop marketplace coverage, ends Advance Premium Tax Credit (APTC) eligibility for any month they're offered affordable employer coverage, and may trigger APTC reconciliation on the employee's tax return. This guide walks through the timing, employee communication, and tax implications of the transition.
An offer of new employer-sponsored health coverage is a 'qualifying life event' under ACA, giving the employee a 60-day Special Enrollment Period to drop their marketplace plan and enroll in employer coverage (or just terminate marketplace coverage if they don't want the employer plan).
For each month an employee is offered AFFORDABLE employer coverage providing minimum value (MVP), they are NOT eligible for ACA premium tax credits — even if they decline the employer offer. Affordability test for 2026: employee share of employee-only premium ≤ 8.39% of household income. Most employer-sponsored plans satisfy MVP automatically.
Employees who received APTC during a month they were offered affordable employer coverage may owe APTC repayment when filing the next 1040 (Form 8962). Worked example:
| Item | Amount |
|---|---|
| Employee received marketplace APTC Jan-March (3 months × $400) | $1,200 |
| Employer offered affordable group coverage starting April 1 | — |
| Employee drops marketplace and enrolls in group April 1 | — |
| APTC eligibility for April-Dec ends | $0 APTC for those months |
| No reconciliation issue (employee dropped marketplace promptly) | — |
Trouble arises when an employee continues to receive APTC after the employer offer date. Even if they don't enroll in the employer plan, the offer disqualifies them from APTC and they must repay.
| Days Before Coverage Effective Date | Action |
|---|---|
| 60-90 days before | Announce new group plan; provide SBC documents |
| 30-45 days before | Open enrollment meetings; collect election forms |
| 14-30 days before | Final election deadline; instruct employees to log into healthcare.gov to terminate marketplace coverage |
| 1-7 days before | Confirm enrollment with carrier; ID cards issued |
| Day 1 | Group coverage effective; marketplace coverage should be terminated |
Employees must log into healthcare.gov (or call the FFM call center) to cancel their marketplace coverage. Effective dates are flexible — employees can pick the day before group coverage starts. Employers cannot cancel on the employee's behalf.
If the goal is supporting employee individual coverage rather than displacing it, an ICHRA may be a better fit. With ICHRA, employees keep their marketplace plans (or buy any individual plan) and the employer reimburses tax-free. APTC interaction is different: employees who accept ICHRA generally cannot also receive APTC on the same plan, so a careful affordability analysis matters.
If the employee's situation is materially worse under the group plan, consider whether the offer is truly 'affordable' under ACA's 8.39% household income test. If the employee can demonstrate hardship, they may be able to keep marketplace coverage with APTC. ICHRA can be a more flexible alternative.
Best practice is 30+ days for open enrollment. Carriers and ICHRA platforms have minimum windows. ACA SEP is 60 days from the qualifying event (employer offer), so employees have time to evaluate.
Yes — they can decline the employer offer and keep marketplace coverage. But APTC is unavailable for any month they're offered affordable employer coverage. Most employees end up financially better off taking the group plan.
