Short answer: Yes—you can contribute to your HSA if you were covered by an HDHP on the first day of the last month of the tax year (the Last Month Rule).

Yes, partial-year HDHP HSA contributions

If you're wondering whether you can contribute to your Health Savings Account (HSA) if you only had a High Deductible Health Plan (HDHP) for part of the year, the answer is yes! Here's what you need to know:

When you have an HSA and an HDHP, you are eligible to make contributions to your HSA as long as you were covered by an HDHP on the first day of the last month of the tax year.

Last Month Rule and coverage dates

For example, if you had an HDHP starting on July 1st, you can contribute to your HSA for the entire year as long as you were enrolled in the HDHP on December 1st. This is known as the Last Month Rule.

It's important to keep track of your HDHP coverage dates to ensure you are eligible to contribute to your HSA. If you were not covered by an HDHP for the full year, your contribution limit may be prorated based on the number of months you had HDHP coverage.

To qualify, you need to be enrolled in an HDHP on the last day of the tax year, which is December 1st if you had coverage starting on July 1st. This unique provision is often referred to as the Last Month Rule, and it’s designed to help individuals maximize their savings.

Tax-deductible benefits and getting help

Remember that HSA contributions are tax-deductible and can help you save for future medical expenses. If you're unsure about your eligibility to contribute to an HSA, it's always a good idea to consult with a financial advisor or tax professional.

If you're curious about making contributions to your Health Savings Account (HSA) while only having a High Deductible Health Plan (HDHP) for part of the year, you're in luck! The good news is that you can absolutely contribute to your HSA under these circumstances.
