The maximum you may contribute to your Health Savings Account is the amount set by federal law for your coverage level and age. The following table shows the 2017 IRS limits:
2017 Federal Limit Over 55
Self-Only $3,400 $4,400
Family $6,750 $7,750
If you have reached age 55 (or will reach age 55 during the year) federal law allows you to make an additional contribution to your HSA. The amount allowed as a “catch-up” contribution for 2017 is $1,000.
Eligibility to make both regular and catch-up contributions ends when you enroll in Medicare.
Note: If you leave an HSA-eligible medical plan before the year end, then your contribution limits will be prorated.
