Is ACA only for full-time employees?

Yes, paid time off (PTO) counts toward ACA hours. Under the Affordable Care Act (ACA), the Internal Revenue Service (IRS) defines an "hour of service" as any hour for which an employee is paid or entitled to payment. This applies whether they are actively performing duties or not.

What Hours Count for the ACA?

When tracking hours to determine full-time status (averaging 30 hours per week or 130 hours per month), employers must include:

• All hours physically worked (including overtime).
• Paid Time Off (PTO) and paid vacations.
• Paid sick leave and paid medical leaves.
• Paid holidays.
• Paid jury duty or paid military leave.
• Paid leaves of absence.

Note: There is a 160-hour cap for a single continuous period of paid non-working time (such as extended paid sick leave), meaning employers do not have to credit more than 160 hours for a single continuous absence, though regular PTO and vacation generally accrue as standard hours of service.

What Does Not Count?

• Unpaid leave: Regular unpaid hours generally do not generate hours of service, though special protected leaves (like unpaid FMLA or USERRA military leave) require employers to calculate averages by excluding those weeks to prevent deflating the employee's average.
• Workers' compensation or outside disability insurance: Payments received from third-party insurance or state funds rather than directly from the employer's payroll typically do not count.

Important Distinction: ACA vs. Overtime (FLSA)

It is common to confuse ACA rules with overtime rules. Under the Fair Labor Standards Act (FLSA), PTO does not count toward the 40-hour workweek threshold required to earn overtime pay. However, for ACA benefits eligibility, it absolutely must be counted.

Employers with fewer than 50 full-time and full-time equivalent employees are exempt from the Affordable Care Act (ACA) employer mandate and do not have to pay penalties if they do not provide health insurance.

Small Business Exemption Basics

• Threshold: Businesses averaging fewer than 50 full-time or part-time combined equivalent workers (FTEs) in the prior calendar year are exempt.
• No Penalties: Exempt small employers never face the Employer Shared Responsibility Payment, even if they choose not to offer health coverage.
• No Mandate: They are not legally required to buy or offer group health plans.

Important Rules for Small Businesses That Offer Coverage

Even though small employers under 50 are exempt from the mandate, they must still follow certain guidelines if they do decide to offer health insurance:

• Provide a 90-day maximum waiting period for eligible workers.
• Create and distribute a Summary of Benefits and Coverage (SBC).
• Comply with basic reporting if providing self-insured coverage (such as Form 1095-B).

Following the expiration of enhanced Affordable Care Act Marketplace Subsidies at the end of 2025, virtually all subsidized enrollees face increased costs, with higher-income earners and older adults losing eligibility or seeing the steepest spikes.

Who is Most Affected

• High-Income Earners (Above 400% FPL): Individuals and households earning more than 400% of the federal poverty line completely lose eligibility for premium tax credits, as the previous income cap returned.
• Older Adults (Aged 50 to 64): Near-retirees face severe premium spikes and total subsidy cliffs at higher income brackets, driving high rates of coverage loss.
• Self-Employed and Middle-Class Workers: Small business owners, farmers, freelancers, and contractors who do not receive employer-sponsored insurance bear the brunt of doubled average premiums.
• Low- and Moderate-Income Enrollees: While lower-income tiers retain baseline subsidies under the original ACA rules rather than losing assistance entirely, their required percentage of income spent on premiums has risen substantially.

There is no maximum income limit to buy an Obamacare (Affordable Care Act) health insurance plan through the Health Insurance Marketplace, but there is a maximum income limit to qualify for financial help or subsidies.

Subsidy Income Limits (The "Subsidy Cliff")

Financial assistance (premium tax credits) is generally available only for households earning up to 400% of the Federal Poverty Level (FPL).

For 2026 coverage, the approximate maximum income thresholds to qualify for subsidies are:

• 1 person: $62,600
• 2 people: $84,600
• 3 people: $106,600
• 4 people: $128,600

Note: Income limits are higher in Alaska and Hawaii due to higher federal poverty guidelines.

Buying Without a Subsidy

If your household income is above 400% of the FPL, you can still enroll in an Obamacare plan through the official HealthCare.gov portal during open enrollment or a special enrollment period, but you will pay the full, unsubsidized monthly premium.

The main disadvantage of marketplace health insurance is that plans often feature restrictive provider networks and high out-of-pocket costs if you do not qualify for substantial financial subsidies.

Key Disadvantages

• Restrictive Networks: Most marketplace options use Health Maintenance Organization (HMO) or narrow networks. This limits your choice of doctors and hospitals, and out-of-network care is typically not covered at all.
• High Out-of-Pocket Costs: Lower-cost plans (like Bronze or Silver tiers) come with high deductibles, copays, and out-of-pocket maximums before full benefits kick in.
• Cost Without Subsidies: If your income exceeds the threshold for federal financial assistance, monthly premiums can be very expensive compared to group or employer-sponsored plans.
• Deductible Resets: If you switch to a marketplace plan mid-year (such as after leaving a job), your deductible usually resets to zero, meaning previous payments toward your old plan do not carry over.
• Limited Enrollment Windows: You can generally only sign up during the yearly open enrollment period, unless you experience a qualifying life event like marriage or job loss.
