The Affordable Care Act (ACA) requires most Americans to maintain minimum essential health insurance coverage or pay a penalty. For 2018, the IRS established specific rules for calculating this penalty based on household income. This guide explains how the penalty works, provides a calculator to determine your liability, and answers common questions about the 2018 health insurance mandate.
How the Penalty is Calculated
The health insurance penalty for 2018 was based on your household income and the number of months you lacked qualifying health coverage during the year. The IRS used the following formula to calculate the penalty:
Penalty Formula
Penalty = (Monthly Premium × 2) × Number of Uncovered Months
The "Monthly Premium" is determined by your household income level, as shown in the table below.
The penalty was applied to each adult in the household who lacked coverage. Children under 19 were not subject to the penalty. The maximum penalty for 2018 was $2,085 per adult, which applied if you had no coverage for the entire year.
Important Notes
- The penalty was only applicable to individuals who were not exempt from the coverage requirement.
- Households could qualify for subsidies to help pay for marketplace coverage, which could reduce or eliminate the penalty.
- The penalty was not applied to individuals who had a qualifying reason for not having coverage, such as being incarcerated or experiencing a hardship.
Penalty Amounts by Income Level
The monthly premium portion of the penalty was based on your household income, as shown in the following table:
| Household Income Level | Monthly Premium | Maximum Penalty (12 Months) |
|---|---|---|
| Below 138% of federal poverty level | $0 | $0 |
| 138% to 200% of federal poverty level | $97.60 | $2,342.40 |
| 200% to 300% of federal poverty level | $224.80 | $5,395.20 |
| 300% to 400% of federal poverty level | $492.40 | $11,817.60 |
| Above 400% of federal poverty level | $860.00 | $20,640.00 |
For 2018, the federal poverty level for a family of four was $24,600. The penalty amounts were adjusted based on your specific household size and income.
Example Calculation
A single person with an income of $30,000 (250% of the federal poverty level for a single person) would have a monthly premium of $492.40. If they had no coverage for 6 months, their penalty would be:
Penalty = ($492.40 × 2) × 6 = $5,908.80
Exemptions and Special Circumstances
Not everyone was required to pay the health insurance penalty in 2018. The following groups were exempt:
- Low-income individuals: Those with incomes below 138% of the federal poverty level were not subject to the penalty.
- Full-time students: Individuals who were enrolled full-time in a degree-granting program were exempt.
- Hardship exemptions: The IRS allowed exemptions for individuals who could not obtain coverage due to financial hardship.
- Incarceration: Individuals who were incarcerated were exempt from the penalty.
- Religious objections: Conscientious objectors to health insurance coverage were exempt.
If you were exempt from the penalty requirement, you did not need to use this calculator. However, if you believe you may have been incorrectly assessed a penalty, you could file an appeal with the IRS.
