If your coverage status changes during the plan year, it can affect how much you can contribute to your Health Savings Account (HSA) for that year. Learn how a person’s HSA contribution limits can change due to a mid-year status change.
As an HSA owner, you can change how much you contribute (up to the IRS annual limit) at any time during the plan year. However, if you have a life-changing event that leads to an insurance change from individual to family coverage (or vice versa), your HSA annual contribution limit could be affected.
It’s important to remember that with an HSA, you can only contribute if actively enrolled in an HSA-qualified, high-deductible health plan (HDHP). Events that can trigger a change of status include:

Let’s talk about the Full-Contribution Rule, also called the “greater of” rule. Issued by the IRS in 2008 (see IRS Notice 2008-52), this rule explains how the new contribution limit is calculated when an HSA account owner has a mid-year status change.
Suppose the HSA owner is HSA-eligible for the entire 2023 plan year and enrolls effective January 1 as an individual. During the year, s/he gets married and changes HDHP coverage from individual to family. In that case, s/he may contribute up to the greater of:
The account owner calculates what the annual limit would be under each option. The highest of the two results is the account owner’s annual HSA contribution limit for that plan year (in this example, for 2023). Here are two sample scenarios that should help make this easier to understand.
Switching from individual to family coverage is pretty straightforward. For example, Linda Lou starts with individual coverage for 2023 but switches to family coverage starting August 1.
Under the “greater of” provision of the Full-Contribution Rule, Linda can contribute $7,750 for that year. Here’s the detailed calculation for Option 1.
Months in 2022 | Amount from Limitation Chart (see Form 8889 instructions) |
January | $3,850 |
February | $3,850 |
March | $3,850 |
April | $3,850 |
May | $3,850 |
June | $3,850 |
July | $3,850 |
August | $7,750 |
September | $7,750 |
October | $7,750 |
November | $7,750 |
December | $7,750 |
Total for all months | $65,700 |
Limitation. Divide the total by 12. | $5,475 |
But what if Linda Lou starts with family coverage but then switches to individual coverage starting August 1? For January through July, her annual contribution limit was $7,750. However, starting August 1, her limit dropped to $3,850.
Again, Linda would calculate her annual contribution limit for 2023 based on Options #1 and #2 outlined above.
Using the “greater of” provision of the Full-Contribution Rule, Linda can contribute $6,125 for 2023. Starting January 1, 2024, the standard annual maximum for her coverage status will apply.
