HSA Limit for Partial-Year Family Coverage
By Brian Gilmore | Published June 15, 2018
Question: An employee who began the year in employee-only HDHP coverage was recently married and enrolled her new spouse mid-year. What is the HSA contribution limit for HSA-eligible individuals enrolled part of the year in employee-only HDHP coverage, and part of the year in family HDHP coverage?
Compliance Team Response:
The HSA contribution limits are calculated on a monthly basis. This means the employee is able to contribute 1/12 of the employee-only limit for the months of the year in employee-only HDHP coverage, and 1/12 of the family limit for the months of the year in family HDHP coverage.
The employee’s overall annual contribution limit is the sum of those two prorated employee-only and family contribution numbers.
You look to the coverage in effect as of the first day of each calendar month to determine whether the employee has employee-only or family HDHP coverage for that month
The IRS has a chart to handle this calculation on page four of the Form 8889 Instructions. You just need to adjust the numbers for the current-year contribution limits.
For more details on how the HSA contribution limit applies in other situations, see slides 11-18 of our Newfront Office Hours webinar Go All the Way With HSA: Everything HDHP/HSA You Need to Know.
