The ACA affordability rule is one of the most misunderstood parts of the Marketplace. It determines who can receive subsidies. In 2026, that affordability threshold is 9.96% of household income.
Most people assume this percentage applies to the entire family, but it doesn’t. The affordability test only applies to the employee’s cost for the lowest-priced self-only plan offered by the employer. It does not apply to the spouse, children or the full family premium.
This is where many families get into trouble. Under ACA rules, affordability is calculated separately for the employee, the spouse and each dependent child. That means the employee may not qualify for subsidies, but the spouse and children might — especially if the family premium is high compared to household income.

Why This Rule Matters So Much
When families misunderstand the affordability rule, they can lose subsidies, pay too much for employer coverage or end up uninsured. Employees may be ineligible for help while spouses and dependents remain eligible, yet many families never realize this. Incorrect assumptions can cost thousands of dollars each year.
