HSA Compliance: What You Need to Know

Health Savings Accounts offer a uniquely powerful triple tax advantage: contributions are tax-deductible, investment growth is tax-free, and withdrawals for qualified medical expenses are never taxed. However, these generous benefits come with strict IRS rules that, if violated, can result in significant penalties and additional taxes. Understanding these rules is essential for anyone who contributes to, invests in, or withdraws from an HSA.

Annual Contribution Limits and How They Are Enforced

Each year the IRS sets maximum contribution limits for HSAs. For 2026, the limit is $4,400 for self-only HDHP coverage and $8,750 for family coverage. Individuals age 55 or older can contribute an additional $1,000 as a catch-up contribution. These limits represent the combined total from all sources: your personal contributions, employer contributions, and contributions from any other person. The IRS enforces these limits through Form 8889, which you must file with your annual tax return. Your HSA custodian also reports contributions to the IRS on Form 5498-SA, making it straightforward for the IRS to identify over-contributions.

Excess Contribution Rules and the 6% Penalty

If the total contributions to your HSA exceed the annual limit, the excess amount is subject to a 6% excise tax for every year it remains in the account. This penalty is reported on IRS Form 5329 and is due with your tax return. The penalty applies each year until the excess is corrected. For example, a $500 excess contribution left uncorrected for three years would generate $90 in cumulative penalties ($30 per year). To avoid the penalty, you must withdraw the excess contributions plus any net income attributable to those contributions before your tax filing deadline (typically April 15 of the following year, including extensions). The withdrawn excess is not included in income, but any attributable earnings are taxable in the year of the withdrawal. Alternatively, you can apply the excess to the following year's contribution limit, though the 6% penalty still applies for the year of the over-contribution.

Did you know?

You have until your tax filing deadline (typically April 15 of the following year, including extensions) to withdraw excess HSA contributions and avoid the 6% excise tax. Contact your HSA custodian to request a "return of excess contribution" as soon as you discover the issue. The excess itself is not taxed on withdrawal, but any attributable earnings are taxable.

Distribution Rules

Qualified vs. Non-Qualified Distributions

HSA distributions are tax-free only when used for qualified medical expenses as defined in IRS Publication 502. Qualified expenses include doctor visits, prescription medications, dental care, vision care, mental health services, and many other medical costs for you, your spouse, or your dependents. Expenses that do not qualify include cosmetic surgery, gym memberships, health insurance premiums (with limited exceptions), and over-the-counter items that are not medicines or medical devices. The determination of whether an expense qualifies is based on when the expense was incurred, not when it was paid. An expense incurred before you established your HSA is never a qualified expense, even if you pay it after opening the account.

The 20% Penalty for Non-Qualified Distributions

If you take an HSA distribution for a non-qualified expense and you are under age 65, the amount is included in your gross income and subject to an additional 20% penalty tax. This means a $1,000 non-qualified distribution could cost a taxpayer in the 22% bracket a total of $420 in taxes and penalties ($220 income tax + $200 penalty). Once you reach age 65, enroll in Medicare, or become disabled, the 20% penalty no longer applies. Non-qualified distributions after age 65 are simply taxed as ordinary income, similar to a traditional IRA distribution. This makes the HSA function as a supplemental retirement account after 65, with the added benefit that qualified medical distributions remain completely tax-free at any age.

Example

A $1,000 non-qualified distribution for someone in the 22% federal tax bracket: $220 income tax + $200 penalty (20%) = $420 total cost. After age 65, the same distribution would cost only $220 in income tax with no penalty.

Form 8889 Reporting Requirements

Every HSA owner must file IRS Form 8889 with their federal tax return if any contributions were made, any distributions were taken, or the account ownership changed during the year. Form 8889 has three parts. Part I calculates your allowable deduction for personal contributions. Part II reports all distributions and determines whether they were for qualified medical expenses. Part III computes any additional tax owed on excess contributions. Failure to file Form 8889 when required can result in IRS inquiries and potential penalties for underreporting. Even if your employer makes all contributions through payroll deductions and you did not take any distributions, you are still required to file Form 8889 to report the employer contributions.

Important

You must file IRS Form 8889 with your federal tax return every year that contributions are made or distributions are taken from your HSA, even if your employer handles all contributions through payroll. Failure to file can trigger IRS inquiries and penalties for underreporting.

Mid-Year Eligibility Changes

Pro-Rata Rules for Mid-Year Eligibility Changes

If you are not HSA-eligible for the entire calendar year (for example, you enrolled in an HDHP in April or dropped your HDHP in September), your contribution limit is generally prorated. The IRS uses a first-of-the-month rule: you are considered an eligible individual for a given month only if you meet all HSA eligibility requirements on the first day of that month. Your prorated limit equals the annual limit divided by 12, multiplied by the number of months you were eligible. For example, if you had self-only coverage for 8 months of 2026, your limit would be $2,933 (8/12 of $4,400). The catch-up contribution for those 55 and older is prorated using the same formula. Understanding pro-rata calculations is critical for anyone who changes jobs, switches health plans, or gains or loses HDHP coverage during the year.

Example

Self-only coverage for 8 months of 2026: $4,400 / 12 x 8 = $2,933 prorated limit. If you switch from self-only to family coverage mid-year, calculate each period separately and add them together.

The Last-Month Rule

Full-Year Contribution With Partial-Year Eligibility

The IRS provides an important exception to the pro-rata calculation through the "last-month rule." If you are an eligible individual on the first day of the last month of the tax year (December 1 for calendar-year taxpayers), you are treated as having been eligible for the entire year. This means you can contribute the full annual maximum, even if you only became HSA-eligible partway through the year.

For example, if you switched from a traditional health plan to an HDHP on September 1 of 2026 and were still eligible on December 1, you could contribute the full $4,400 (self-only) or $8,750 (family) instead of a prorated amount for only 4 months.

However, the last-month rule comes with a critical requirement: the 13-month testing period. You must remain an eligible individual from December 1 of 2026 through December 31 of 2027. If at any point during this testing period you lose your HSA eligibility (for example, by switching to a non-HDHP plan, enrolling in Medicare, or gaining disqualifying coverage), the amount by which your contributions exceeded the prorated limit is included in your gross income and subject to an additional 10% tax. Before relying on the last-month rule, make sure you are confident you can maintain your HSA eligibility for the full 13-month period.

Important

If you use the last-month rule to contribute the full annual maximum, you must remain HSA-eligible for the entire 13-month testing period (December 1 of the contribution year through December 31 of the following year). Failing this test means the excess above your prorated limit is added to your gross income and subject to an additional 10% tax.

Frequently Asked Questions

How do I correct an over-contribution to my HSA?

If you contributed more than the IRS-allowed maximum to your HSA, you must withdraw the excess amount plus any earnings attributable to those excess contributions before your tax filing deadline (typically April 15 of the following year, including extensions). Contact your HSA custodian to request a "return of excess contribution." The excess amount will not be taxed when withdrawn, but any attributable earnings will be included in your gross income for the year. If you miss the deadline, the 6% excise tax applies to the excess for each year it remains in the account. You can also apply the excess to the following year's limit if you have room, but the 6% penalty still applies for each year the excess existed.

What is Form 8889?

Form 8889, "Health Savings Accounts (HSAs)," is the IRS form used to report HSA contributions, calculate your deduction, report distributions, and determine whether any taxes or penalties are owed. You must file Form 8889 with your federal tax return if you (or someone on your behalf, including your employer) made contributions to your HSA, took distributions from your HSA, or acquired an interest in an HSA because of the death of the account beneficiary. The form has three parts: Part I calculates your HSA deduction for contributions, Part II reports distributions and whether they were for qualified medical expenses, and Part III calculates the additional tax on excess contributions. Even if your employer made all the contributions through payroll, you are still required to file Form 8889.

Do employer contributions count toward the limit?

Yes. Employer contributions to your HSA are included in the total annual contribution limit set by the IRS. For 2026, the combined total of your personal contributions plus your employer's contributions cannot exceed $4,400 for self-only coverage or $8,750 for family coverage. Many employees overlook this when calculating how much they can contribute personally. For example, if your employer contributes $1,500 to your HSA and you have self-only coverage, you can only contribute an additional $2,900 yourself. The catch-up contribution of $1,000 for those 55 and older is in addition to the standard limit and is available only for your own contributions. Employers cannot make catch-up contributions on your behalf.

What happens if I change coverage mid-year?

If you switch between self-only and family HDHP coverage during the year, your contribution limit is calculated using the greater of the two limits based on the "last-month rule" or a pro-rata calculation. Under the pro-rata method, you calculate your limit for each month based on the type of coverage you had on the first day of that month, then add the monthly amounts together. For example, if you had self-only coverage for 6 months and family coverage for 6 months, your limit would be (6/12 x $4,400) + (6/12 x $8,750) = $6,575. If you were eligible on December 1, you may use the last-month rule to apply the December coverage type to the full year, but you must remain eligible with that coverage type for the following 13-month testing period.

Can my spouse and I both have HSAs?

Yes, both spouses can have their own individual HSAs, but the combined contributions across both accounts are subject to limits that depend on your coverage types. If both spouses have self-only HDHP coverage, each can contribute up to the self-only limit ($4,400 for 2026) to their own HSA independently. If either spouse has family HDHP coverage, the combined contributions to both HSAs cannot exceed the family limit ($8,750 for 2026). You can split this limit between the two accounts however you choose. Each spouse who is 55 or older can make an additional $1,000 catch-up contribution to their own HSA. Catch-up contributions are per-person and are not subject to the combined family limit.

What records should I keep for HSA compliance?

You should maintain thorough records to substantiate both your contributions and distributions. For contributions, keep records of all deposits including dates, amounts, and sources (personal, employer, rollover). For distributions, keep receipts, invoices, and explanations of benefits (EOBs) for every medical expense paid with HSA funds. These records should show the date of the expense, the amount, the provider, and a description of the service proving it is a qualified medical expense under IRS Publication 502. The IRS recommends keeping these records for at least three years after filing your tax return, though some advisors suggest keeping them indefinitely since there is no deadline for reimbursing yourself from an HSA for qualified expenses incurred after the account was established.
