Short answer: If you contribute above the IRS annual HSA limit, the excess is subject to a 6% excise tax and must be corrected to avoid ongoing penalties.

Consequences of HSA overfunding rules

If you overfund your HSA, there are consequences you should know about. Health Savings Accounts (HSAs) are a great way to save for medical expenses while enjoying tax benefits. However, it's essential to understand the rules and limits to avoid any penalties. Here's what happens if you contribute too much to your HSA:

1. Excess Contributions: Any amount you contribute above the IRS annual limit is considered excess. For 2021, the limit is $3,600 for individuals and $7,200 for families.

2. Penalties: If you overfund your HSA, you will have to pay a 6% excise tax on the excess amount. This tax is not deductible and will be owed yearly until you correct the over-contribution.

3. Correcting the Excess: To avoid penalties, you can withdraw the excess contributions before the tax filing deadline for that year. This withdrawal would be subject to income tax but not the excise tax.

4. Reporting: You must report the excess contributions on your tax return using IRS Form 8889. Failure to do so may result in additional penalties.

When you contribute too much to your HSA, it's crucial to act quickly to rectify the situation. Overfunding may lead to unnecessary complications and financial penalties. Make sure to keep track of your contributions throughout the year to stay within the IRS limits: $3,600 for individuals and $7,200 for families in 2021.
