What is the Maximum Contribution I Can Make to an HSA if I Started in August?

If you started contributing to a Health Savings Account (HSA) in August, you may be wondering what the maximum amount you can contribute for the year is. HSAs are a great way to save for medical expenses while enjoying tax benefits, but it's essential to know the limits to maximize your savings.

For individuals, the maximum HSA contribution for 2021 if you started in August is prorated based on the number of months you were eligible to contribute. The annual limit set by the IRS for 2021 is $3,600 for individuals and $7,200 for families.

Here's how you can calculate your maximum HSA contribution if you started in August:

  • Determine the number of months remaining in the year after August.
  • Divide the annual contribution limit by 12 to get the monthly limit.
  • Multiply the monthly limit by the number of months remaining.

It's important to note that contributions made by your employer also count towards the annual limit. If you're 55 or older, you can make an additional catch-up contribution of $1,000.
