When Can You Make HSA Contributions Elective for the Previous Tax Year?

Health Savings Accounts (HSAs) are a valuable tool for individuals to save money tax-free for medical expenses. One common question that arises is when you can make HSA contributions elective for the previous tax year.

Contributions to an HSA can typically be made for the current tax year until the tax filing deadline, which is usually April 15th of the following year. However, there are specific rules and deadlines for making contributions elective for the previous tax year:

  • If you are eligible to contribute to an HSA for the previous tax year, you can make those contributions up until the tax filing deadline for that year.
  • For example, if you want to make HSA contributions for the 2021 tax year, you can do so until April 15, 2022.
  • It's important to note that you must have been eligible to contribute to an HSA for the entire tax year in order to make contributions for that year.
  • Individuals have the flexibility to make contributions for the previous tax year even after the new tax year has begun, as long as they meet the eligibility requirements.

Understanding the rules and deadlines for making HSA contributions elective for the previous tax year can help individuals maximize their tax savings and take full advantage of their HSA benefits.


Health Savings Accounts (HSAs) provide an excellent opportunity to set aside money for unexpected medical expenses while also enjoying tax benefits. A common inquiry is regarding the timing for making contributions for a previous tax year.

Typically, contributions for the current tax year can be made until the tax filing deadline, generally on April 15 of the following year. However, specific guidelines dictate when you can make contributions claimed for the past year:

  • If you qualify to contribute to an HSA for that past year, you have the ability to make these contributions up until the pertinent tax filing deadline.
  • For instance, to contribute for the 2021 tax year, you can continue to do so until April 15, 2022.
  • Keep in mind that you must have met the eligibility criteria for the full tax year to be able to contribute for that year.
  • This flexibility not only allows contributions beyond the new tax year but also equips individuals with maximum control over their tax strategies, provided they adhere to eligibility conditions.
