Short answer: You may owe a 6% excise tax if you contribute more than the allowed HSA contribution limit, generally avoidable by withdrawing excess by the tax filing deadline.

What triggers the HSA excise tax

Health Savings Accounts (HSAs) are a great way to save for medical expenses while enjoying tax benefits. However, there are limits to how much you can contribute to your HSA each year. If you contribute more than the allowed amount, you may be subject to a 6% excise tax on excessive HSA contributions.

It's essential to monitor your HSA contributions to ensure you stay within the allowable limits and avoid being subject to the 6% excise tax on excessive contributions.

Health Savings Accounts (HSAs) not only help you save for future medical expenses but also provide excellent tax advantages for both contributions and growth. However, it’s essential to understand the contribution limits imposed by the IRS, as exceeding these limits can lead to unnecessary penalties.

How the 6% excise tax works

The 6% excise tax on excessive HSA contributions works as follows:

  • Contributions to your HSA are tax-deductible, and any earnings grow tax-free.
  • For 2021, the annual contribution limits are $3,600 for individuals and $7,200 for families.
  • If you contribute more than the allowed contribution limit, the excess amount is subject to the 6% excise tax.
  • The excise tax is imposed each year that the excess contributions remain in the account.
  • To calculate the excise tax owed, you must file Form 5329 with your tax return.
  • If you have excess contributions, you have until the tax filing deadline (generally April 15) to withdraw the excess amount to avoid the excise tax.
  • If you do not withdraw the excess contributions by the deadline, the 6% excise tax will apply to the excess amount each year until it is corrected.
