HSA Timing: Expenses Before You Open the Account

Short answer: Publication 969 says you can receive tax-free HSA distributions to pay or be reimbursed for qualified medical expenses you incur after you establish the HSA. Other distributions are subject to income tax and may be subject to an additional 20% tax. So timing of account opening can matter for which expenses can be reimbursed.

Notes

• You don't have to take distributions each year.
• Distributions are reported by the trustee on Form 1099-SA.
• Contributions and the year-designation deadline are separate: see the contribution deadline.
• Eligibility to contribute starts with the months you are an eligible individual with qualifying coverage (bronze/catastrophic plans).

Made-up example

An HSA opened on March 1 can generally pay tax-free for qualified expenses incurred on or after that date; a dentist bill from February is not covered, per the publication's wording. When the account is considered "established" can depend on state law; we did not verify that point.

FAQ

Is a claim date the same as incurred date? The publication refers to when the expense is incurred.

Is the 20% tax always applied? The publication says it may apply; exceptions exist (age 65, disability, death per earlier research).

What we could not verify

• How an HSA is "established" for this rule (state law, trustee) is not covered in the pages read.
• 2026 edition of Pub. 969.
