When Can You Make Last HSA Contributions for Prior Year?

One common question many people have about Health Savings Accounts (HSAs) is when they can make last-minute contributions for the previous year. Understanding the deadline for contributing to your HSA can help you maximize its benefits and tax advantages.

Contributions to an HSA can be made up until the tax filing deadline for the year, typically April 15th of the following year. However, there are a few key details to keep in mind:

  • If you want to make a contribution for the previous tax year, you must do so before the tax filing deadline, not including extensions.
  • For example, if you want to make a contribution for the 2021 tax year, you have until April 15, 2022, to do so.
  • Contributions made after the deadline will count towards the current tax year.

Being aware of the deadline for HSA contributions can help you make informed decisions about maximizing your tax savings and healthcare expenses. It's important to plan ahead and ensure you make any necessary contributions before the deadline passes.


Many individuals often wonder about the cut-off for making HSA contributions for the previous year, and the understanding of this deadline can significantly enhance your ability to leverage tax benefits.

You can contribute to your HSA for a prior tax year until the tax filing due date, which is generally April 15 of the following year. Make sure you keep the following points in mind:

  • If you are aiming to contribute for the year 2021, you have until April 15, 2022, to make that contribution.
  • Anything contributed post-deadline will instead go towards the current tax year, which might alter your tax planning.

Timely contributions can lead to increased savings and better management of your healthcare expenses, so mark your calendars and plan accordingly!
