Frequently Asked Questions

Can employee pretax HSA contributions be changed throughout the year?

Yes. Eligibility requirements and contribution limits for HSAs are determined on a month-by-month basis. You can start or stop contributing or increase or decrease the amount at any time, if the change is made after the change request is received.

Can I contribute to an HSA at the same time as an FSA and/or HRA?

You can contribute to an HSA while covered by the following types of medical FSAs and/or HRAs:

  • Limited purpose FSA and/or HRA
  • Suspended HRA
  • Post-deductible FSA and/or HRA
  • Retirement HRA

You cannot contribute to an HSA while covered by the following types of medical FSAs:

  • A general purpose medical FSA that pays for all eligible expenses
  • A general purpose medical FSA with a grace period (unless the FSA has a $0 balance at the end of the plan year)
Do both employer and employee contributions count toward the annual contribution maximum?
Yes. Both employer and employee contributions are combined with calculating the maximum.
For new HSAs, are maximum contributions prorated on a monthly basis?
Annual HSA contributions for new HSAs are not prorated on a monthly basis as long as you are HSA- eligible on December 1 and maintain HDHP coverage throughout the subsequent 13-month testing period. The testing period begins on December 1 in the year the qualified HDHP coverage is obtained and runs through December 31 of the following year. The testing period is also called the “13-month rule.” Enrolling in an HDHP and establishing an HSA any time after January 1 triggers the “testing period” if you contribute the maximum amount to your HSA. If you do not satisfy the 13-month rule, contribution limits are prorated and tax consequences apply. See Chapter 5, Section 1.2 on page 37 for examples of pro-rated maximum contribution amounts.


This section contains guidance on contributing funds to your HSA. For other account types, you will choose an election amount when you enroll. For guidance in election amounts, see the Getting Started section.
