How Late Can You Make Contributions to an HSA?

For those with Health Savings Accounts (HSAs), understanding the rules and deadlines for contributions is essential. One common question that arises is, 'How late can you make contributions to an HSA?'

According to the IRS guidelines, the deadline for making contributions to an HSA is the tax return filing deadline, which is usually April 15th of the following year. However, there are a few key points to keep in mind:

  • Even if you file for an extension to submit your tax return, the deadline for HSA contributions remains the same.
  • Contributions must be made before the deadline, not when you file your taxes.
  • If you contribute after the deadline, the amount will not be considered tax-deductible for that particular tax year.

It's important to plan ahead and ensure you make contributions on time to maximize the benefits of your HSA.
