How to Withdraw Excess HSA Contributions: Deadlines and Reporting

To withdraw an excess HSA contribution without a penalty, ask your HSA custodian for a “return of excess contribution” before your federal tax filing deadline, including extensions. The custodian pulls out both the overcontribution and the earnings it generated while sitting in the account, and the IRS then treats the money as though it had never been contributed. Miss that deadline and a 6% excise tax applies for every year the excess stays in the account.¹

Confirm You Actually Have an Excess

Before requesting a withdrawal, verify the number. Everything deposited to your HSA for the year counts toward the same ceiling: your own contributions, payroll deferrals, and anything your employer puts in. Employer money is not extra room. If your employer contributes $2,000 toward family coverage in 2026, the most you can add yourself is $6,750, because the family limit is $8,750.²

For 2026, the limits are $4,400 for self-only HDHP coverage and $8,750 for family coverage, with an additional $1,000 catch-up if you are 55 or older and not enrolled in Medicare.³ The catch-up must go into the account of the spouse who is 55 or older; married couples with family coverage split the family limit between their two HSAs.⁴

Two situations quietly shrink the limit. First, partial-year HDHP coverage: your ceiling is prorated by the month, so seven months of self-only coverage in 2026 caps you around $2,567, not $4,400.⁴ Job changes, Medicare enrollment, and mid-year plan switches are the common triggers. Second, the last-month rule lets you contribute the full annual amount if you had qualifying HDHP coverage on December 1, but only if you stay in an HDHP through December 31 of the following year; drop coverage during that testing period and the extra amount becomes taxable and hit with a separate 10% additional tax.²

Calculate the Earnings You Also Need to Withdraw

A corrective withdrawal has to include the Net Income Attributable (NIA) to the excess: the earnings that portion of your money generated while it was in the HSA.⁵ The formula:

NIA = Excess Contribution × (Adjusted Closing Balance − Adjusted Opening Balance) ÷ Adjusted Opening Balance

The adjusted opening balance is the account value immediately before the excess was deposited, plus any contributions or transfers that arrived during the same computation period. The adjusted closing balance is the value immediately before the corrective withdrawal. If the account lost money over that window, the NIA is negative, and the amount you withdraw is smaller than the original excess.

Most custodians run this calculation for you when you file the request. If yours does not, ask for the opening and closing balances covering the relevant period and compute it yourself. Withdrawing the wrong amount either leaves an excess in the account or creates a taxable distribution outside the corrective process.

Request the Corrective Distribution

Most custodians provide a “Return of Excess Contribution” or “Corrective Distribution” form through their online portal. This is not the same as a normal withdrawal, and using the correct form matters: a corrective distribution coded properly avoids the 20% additional tax the IRS otherwise imposes on HSA withdrawals not spent on qualified medical expenses.⁶

The form typically asks for:

The tax year the excess applied to (which may not be the year the money was deposited)
The principal excess amount
The net income attributable to the excess
How you want the money paid out, usually electronic transfer or a mailed check

Submitting through the secure portal is fastest; most custodians process the distribution within three to seven business days. When the funds arrive, confirm the custodian will code the distribution as “excess contributions” (code 2 on Form 1099-SA). If they use a normal distribution code, request a corrected 1099-SA before you file.⁷

If you have already spent or invested down the balance and the account no longer holds enough to cover the full excess plus NIA, withdraw what you can. The 6% excise tax is calculated on whatever excess remains at year-end, so a partial return still reduces the penalty. You cannot deposit outside money into the HSA just to pull it back out as a correction.

Meet the Deadline

The corrective withdrawal has to happen by the due date of your federal tax return for the year the excess was contributed, including extensions.⁸ For 2025 excess contributions:

April 15, 2026 is the standard deadline. Withdraw by this date and no excise tax applies.
October 15, 2026 applies if you filed a valid extension.⁹

There is also a six-month grace period if you filed on time without an extension and without correcting the excess. You have until six months after the original unextended due date (October 15 for an April 15 filer) to pull the money out, but you must file an amended return (Form 1040-X) with “Filed pursuant to section 301.9100-2” written at the top, along with a corrected Form 8889 and, if applicable, a corrected Form 5329.⁸

Report the Withdrawal on Your Return

The corrective distribution shows up in a few places on your tax return, and getting the numbers to line up is what actually erases the excess in the IRS’s records.

On Form 8889, Line 2 reports your total contributions and Line 13 the deductible portion; the gap is your excess. Line 14b captures the excess plus NIA that you withdrew by the deadline. That entry is what tells the IRS to treat the withdrawn amount as though it had never been contributed.⁸

Your custodian will send Form 1099-SA in January or February. Box 1 is the gross distribution, Box 2 is the earnings on the excess, and Box 3 should show distribution code 2.⁷

The NIA earnings are taxable income in the year of the distribution. They flow through Form 8889 to Schedule 1 (Form 1040), line 8f.¹⁰ The principal excess itself is not taxed again, because it was either never deducted or already included in your W-2 wages.

What If You Missed the Deadline

If the excess is still in the account after every available deadline has passed, the 6% excise tax applies. Report and pay it on Form 5329, Part VII; the tax carries to Schedule 2, line 8.¹¹ The tax equals 6% of the smaller of the excess contribution or the total HSA value on December 31. It repeats every year the excess remains.¹

Two ways to stop the recurring penalty:

Withdraw the excess principal at any time. You owe 6% for each year the excess sat in the account, but pulling it out ends the penalty going forward. After the deadline, you do not include NIA in the withdrawal; you just remove the principal. That withdrawn amount may then be treated as a regular distribution, meaning income tax and the 20% additional tax if not used for qualified medical expenses.
Absorb the excess by contributing less than the annual limit in a future year. The gap between your contribution and the limit applies to the prior excess. Once fully absorbed, the 6% penalty stops, but you owe it for every intervening year.⁸

For small overcontributions, absorbing is sometimes cheaper. A $200 excess costs $12 a year at 6%. Paying that for a year or two while under-contributing can beat owing income tax plus 20% on a late non-qualified withdrawal, especially at higher tax brackets.

Employer Overcontributions

If your employer contributed too much, the employer can ask the custodian to return the excess plus NIA directly to the employer, but only through the end of the tax year in which the contribution was made. If the employer does not reclaim it, the amount must be added to Box 1 wages on your W-2 for that year.⁸ That handles the income-tax side, but the excess is still in your HSA and still needs to come out to avoid the 6% excise tax. If the employer excess was not added to your W-2, report it yourself as “Other income.”² Contact HR or payroll early, because the three-way coordination between you, your employer, and the custodian takes time, and the filing-deadline window is the same.
