3 HSA Pro Tips for Tax Season

Key takeaways:

Tax season is the time to check in on your 2026 contributions. You can still make a prior-year contribution and save more on taxes.
You can also plan your current-year contributions based on last-year's health expenses.
While you're at it, learn more about what's eligible and how to get the most from your HSA in 2026.

Tax Day will be here before you know it. So it’s time to check whether you've maximized your prior-year HSA contributions for the biggest tax savings.

Below, we’ll cover the areas to focus on if you had coverage under an HSA-qualified high-deductible health plan (HDHP) in 2025.

1. Max Out Your Contributions

If you didn’t contribute to your HSA in 2025 or want to contribute more, you have until Tax Day to meet your contribution limit. Tax Day is typically April 15, but the exact deadline can vary by state.

The more you contribute, the more you lower your taxable income.

In 2025, the HSA contribution limit is $4,300 for those participating in an HSA as an individual and $8,550 for those participating in an HSA as a couple or family.
For 2026, those limits have increased to $4,400 and $8,750, respectively.
If you're 55 or older, you can contribute an extra $1,000 each year.

If your HDHP took effect mid-year (as late as December 1, 2025), you can still make the full annual contribution to your HSA before Tax Day as long as you also maintain HDHP coverage for the next 12 months.

If you haven't fully funded your HSA for 2026, take a few minutes to see how much it would change your total tax burden to bump up your HSA contribution for last year. You might be surprised at how much your contribution will pay for itself via a lower tax bill or larger refund.

The HSA Triple Tax Advantage

An HSA has three main tax benefits:

Money that you put into your HSA is pre-tax (either via pre-tax payroll contributions or a deduction on your tax return).
Dividends, interest, and investment gains in your account accumulate tax-free.
Withdrawals are tax free, too (as long as you use the money for qualified medical expenses).

Once you turn 65, you can withdraw money from your HSA for anything you want, without a penalty. You'll have to pay income tax on the withdrawals if you're not using them for qualified medical expenses. But that means you can use your HSA like a traditional IRA once you're 65. So your HSA can serve as a backup retirement account if that's your preference.

2. Take Stock of Your Health Expenses

Tax season is also a good time to review your healthcare spending from the previous year. You can then make sure you’re contributing enough this year to cover everything.

You can also reimburse yourself at any time for purchases you made after you opened your HSA. And any funds you put into your account will lower your taxable income—even if you use them to pay for health expenses within the same year. Your withdrawals for reimbursement are also tax-free.

You can use our Expense Tracker™ app to find, store, and organize your receipts for reimbursement. You're likely already buying products that qualify for reimbursement.

3. Get Smart About HSA Tax Planning for 2026

Finally, tax time is a chance to plan for the year ahead. Here’s how to get the most out of your HSA in 2026:

Get your contributions on track. Make sure you’re contributing enough to cover your health expenses, save for the long term, and get the biggest tax benefit.

It’s never too late to increase your contributions. If you contribute to your HSA via payroll, you’ll want to work with your employer to increase the amount and bring you as close as possible to the contribution limit set by the IRS.

Remember, payroll HSA contributions are made pre-tax. So the resulting reduction in your take-home pay will be smaller than the amount contributed.

In Summary

Tax season is an excellent time to check in on your HSA. It's your last chance to make a prior-year contribution. And it’s an opportunity to make sure your HSA funding is on track for this year.

It's also a good time to remind yourself that the purpose of an HSA is to ensure both financial and physical health. So make sure that you're also spending your HSA funds spending your HSA funds when you need to (that's why an HSA exists, after all).
