Think Your HSA Withdrawals Are Tax-Free? The IRS Still Wants This Form
Every tax season, certain problems appear again and again. One of the most common — and most preventable — involves Health Savings Accounts (HSAs) and missing documentation.
Recently, a client left my office after we discovered exactly this issue. It is extremely common, and it usually happens for one simple reason: everything connected to HSAs now happens electronically.
How the Problem Starts
When reviewing a client’s tax documents, I can often see from the W-2 form that the taxpayer has a Health Savings Account. The existence of the HSA is clearly reported there.
However, many clients do not provide an important additional document: Form 1099-SA.
When I ask whether they used their HSA during the year, the answer is almost always yes. They used it for medical expenses — prescriptions, doctor visits, or other qualified healthcare costs — and they correctly understand that HSA funds used for medical purposes are generally not taxable.
So naturally, they assume nothing else is required.
Unfortunately, that assumption can create problems.
Why the 1099-SA Matters
The Form 1099-SA is not a tax bill. It is a reporting document.
Financial institutions such as Fidelity, HSA Bank, or other administrators send this form both to you and to the IRS. The form reports how much money was withdrawn from the HSA during the year.
Even when withdrawals are completely tax-free, the IRS still expects to see those distributions properly reported on your tax return.
The issue is that many taxpayers never actually receive this form in the mail. Because HSA providers operate almost entirely paperlessly, the document is usually placed in an online account portal.
Many people never log in. Some never even realize they have a separate HSA account managed by a third party.
As a result, the form never makes it to the tax preparer.
What Happens If the Form Is Missing
When the IRS receives a 1099-SA but does not see it reflected on your tax return, their system assumes the withdrawal may have been taxable.
Months later — often around September — taxpayers frequently receive an IRS CP2000 notice.
This notice typically states:
You withdrew money from your HSA
The withdrawal was not reported
Additional tax may be owed
Penalties and interest are being proposed
At that point, what began as a simple oversight turns into stress, paperwork, and delays.
The Good News: It’s Usually Fixable
In most cases, the situation can be corrected by showing that the HSA funds were used for qualified medical expenses. The underlying issue is rarely complicated.
But it is inconvenient.
Responding to IRS notices takes time, documentation, and careful communication — all of which could have been avoided by including one form during tax preparation.
How to Avoid This Problem
If you have a Health Savings Account, take these steps each tax season:
Log into your HSA provider’s online account.
Download Form 1099-SA.
Provide it with your tax documents.
Keep records of medical expenses paid with HSA funds.
Even though qualified HSA withdrawals are not taxed, they still must be reported.
A Simple Reminder
Tax problems are often not caused by complicated law. More often, they result from missing documentation in an increasingly paperless world.
Taking a few minutes to download the correct forms can prevent months of unnecessary correspondence with the IRS.
If you have questions about HSAs or receive an IRS notice related to one, addressing the issue early is always the safest approach.
