When it comes to tax planning and healthcare savings, Health Savings Accounts (HSAs) offer one of the most tax-advantaged strategies. If you made contributions to an HSA, received distributions, or need to report excess contributions during the 2025 tax year, filing IRS Form 8889 is mandatory. Here’s an overview of Form 8889.
Table of Contents
What Is IRS Form 8889?
The official IRS tax form, called Health Savings Accounts (HSAs), is also called Form 8889
Taxpayers use this to report contributions to, and distributions from, a Health Savings Account (HSA). If you have an HSA, you are required to file Form 8889 with your individual income tax return along with IRS Form 1040, 1040-SR, or 1040-NR.
Who Must File Form 8889?
You need to file if you:
- Made or received HSA contributions
- Took HSA distributions (qualified or non-qualified)
- Have an HSA account (even if inactive)
- Need to report excess contributions
- Want to claim HSA deductions
Important: Even if your employer handles contributions, you may still need to file. Professional tax services can assess your specific requirements.
What is Form 8889 used for? What is the Purpose of Form 8889?
IRS Form 8889 serves four key purposes:
1. Report Contributions to an HSA
This includes your contributions through payroll, employer contributions, and any others made on your behalf. The form helps calculate the HSA deduction you may be eligible to claim on your tax return.
2. Report Distributions from the HSA
If you have withdrawn money from your HSA, it must be reported. You also have to report how the funds were utilized, for qualified medical expenses or any other purpose. They are tax-free if they have been used towards qualified medical expenses. If not, the withdrawal is taxable and may incur a 20% penalty if you’re under age 65.
What Is the Last-Month Rule?
The last-month rule allows you to contribute the full annual HSA contribution limit for the year—even if you only became eligible partway through the year—as long as you were HSA-eligible on December 1st of that tax year.
Let’s say you became eligible for an HSA (i.e., enrolled in a High Deductible Health Plan) on December 1, 2025.
What Is the Testing Period?
If you use the last-month rule to make a full-year contribution, you must remain HSA-eligible for the entire “testing period,” which is:
December 1 of the current tax year through December 31 of the following tax year
3. Track Excess Contributions
You need to determine whether you or your employer has contributed more than the annual IRS limit. If you have contributed in excess, it must be reported. The excess is subject to a 6% excise tax per year until corrected.
4. Reconcile Eligibility Rules
If you used the ‘Last-Month Rule’ to claim the full-year contribution but didn’t remain eligible during the “testing period,” you may have to report and pay tax on the ineligible amount.
Who should file IRS Form 8889 for 2025?
You need to file IRS Form 8889 if any of the following apply in 2025:
- You or someone on your behalf (e.g., a family member or employer) contributed to your HSA
- You received HSA distributions during the tax year
- You need to report excess contributions or correct ineligibility during the testing period
This form must be attached to your Form 1040, 1040‑SR, or 1040‑NR.

How to Fill Out IRS Form 8889, or Form 8889 Instructions (Part by Part)
Part I: Contributions & Deductions
- Line 2: Enter after-tax or outside payroll contributions (those not reported on W‑2)
- Line 9: Enter employer or cafeteria-plan contributions (Box 12 code W)
- Calculate your deductible contribution and identify any excess contributions
If you exceed limits and don’t withdraw the excess by April 15, 2026, you’ll owe a 6% excise tax per year on each excess amount.
Part II: Distributions
- Report all HSA withdrawals (line 14a)
- Distinguish amounts used for qualified medical expenses (line 15)
- Non-qualified distributions (if you’re under 65) are taxed as income + 20% penalty
Part III: Income & Penalties
- Report excise tax on uncorrected excess contributions
- Adjustments for last-month rule or testing-period failures (e.g., subsequent ineligibility)
Important Deadlines for 2025
- The contribution deadline is April 15, 2026 (unless extended due to exceptional circumstances)
- To avoid the 6% penalty, you must withdraw any excess contributions (and earnings) by this date.
What are Some Common Pitfalls & Clarifications while filing IRS Form 8889
- Wrong contribution limits cited: Ensure you’re using the latest (2025) values. i.e., $4,300 self, $8,550 family, not 2024 figures.
- Confusing penalties: 6% tax applies to unwithdrawn excess contributions—not the 20% penalty (that’s for non-qualified withdrawals)
- Mixing up contribution lines: Employer contributions are reported separately (Box W → line 9), not with your contributions on line 2
Ignoring the last‑month rule (if you were eligible only part of the year): this might change your permitted limit.
