How Late Can I Make HSA Contributions for Prior Year?

If you are wondering how late you can make HSA contributions for the prior year, here are some important points to consider:

Typically, the deadline for contributing to your HSA for a specific tax year is the same as the tax filing deadline for that year, which is usually April 15th of the following year. However, there are some exceptions and special rules that you should be aware of:

  • If you have an individual HSA, you can make contributions up until the tax filing deadline for that year (usually April 15th).
  • If you have a family HSA, contributions can be made up until the tax filing deadline as well.
  • If you are eligible for an HSA but did not open one during the year, you can establish and fund the HSA by the tax filing deadline for that year.
  • Self-employed individuals have until the tax filing deadline, including extensions, to make HSA contributions.

It's important to note that HSA contributions made between January 1st and the tax filing deadline can be designated for the prior year if desired. This flexibility allows you to maximize your contributions and tax benefits.
