The bottom line: The ACA affordability threshold increased to 9.96% for 2026 (up from 9.02% in 2025). If you're an Applicable Large Employer with 50+ full-time employees, your lowest-cost self-only health plan premium must not exceed 9.96% of the employee's household income. This gives employers slightly more flexibility — but the reporting requirements are stricter than ever.
What Changed for 2026
Every year the IRS adjusts the ACA affordability percentage based on premium growth. For plan years beginning in 2026, the threshold jumped from 9.02% to 9.96% — the largest single-year increase since the ACA was enacted.
This means an employee earning $40,000 annually could now pay up to $332/month for self-only coverage before it's considered "unaffordable" under the ACA — compared to $301/month under the 2025 threshold.
Who This Affects
- Applicable Large Employers (ALEs) — any employer with 50+ full-time employees (including full-time equivalents) during the prior calendar year
- HR and benefits administrators who manage health plan offerings and compliance reporting
- Employees at ALEs who may see changes in employer-sponsored health plan pricing
⚠️ Don't confuse "more flexibility" with "less risk." The higher threshold gives employers room to adjust premiums, but the IRS is simultaneously increasing enforcement of 1095-C reporting accuracy. Penalties for non-compliance under IRC §4980H can reach $2,970/employee for failure to offer coverage (§4980H(a)) and $4,460/employee for unaffordable coverage (§4980H(b)) in 2026.
The 3 ACA Safe Harbors (Still in Effect)
Employers can use any of these three safe harbors to demonstrate affordability — you don't need to know actual household income:
1. W-2 Safe Harbor
The employee's required contribution must not exceed 9.96% of their W-2 Box 1 wages. This is the most common method.
2. Rate of Pay Safe Harbor
The contribution must not exceed 9.96% of 130 monthly hours × the employee's hourly rate (or monthly salary for salaried employees). Best for industries with variable hours.
3. Federal Poverty Line (FPL) Safe Harbor
The contribution must not exceed 9.96% of the federal poverty line for a single individual, divided by 12. For 2026, this means the maximum monthly employee cost is approximately $131/month. This is the simplest method and works for all employees regardless of income.
