Your health savings account (HSA) contributions are tax-deductible in 2026, as long as you’re enrolled in an HSA-eligible high-deductible health plan (HDHP). This deduction matters because it gives you a triple tax advantage:

1. Your contribution is tax-deductible.
2. The growth in your HSA is tax-free.
3. Any qualified withdrawal for a medical expense is also tax-free. 

The Internal Revenue Service updated HSA contribution limits for 2026. Individuals can contribute up to $4,000, and families can contribute up to $8,750. Those 55 and older can also add $1,000 catch-up-contribution. Keep in mind this includes total contributions by you and your employer. 

You can learn how HSA contributions work, how to avoid common mistakes, and smart ways to invest your HSA — plus more helpful tips — in this article.

What Is an HSA and How Does It Work? 

An HSA is a savings account that allows you to set aside pre-tax funds to cover qualified medical expenses. You can potentially pay for copayments, insurance coverage or deductibles from this account without having to tap into your savings. 

Eligibility Requirements

Here are the eligibility requirements for your contribution: 

• Must be enrolled in HSA-eligible high-deductible health plan (HDHP)
• Cannot have any disqualifying coverage like Medicare or a flexible savings account (FSA)
• Another individual cannot claim you as a dependent on their tax return. 

Triple Tax Advantage 

The main advantage of the HSA is the triple tax growth: 

• Tax-deductible: Contributions to an HSA are tax-deductible. 
• Growth without tax liability: Any interest on the earnings in your HSA account grows tax free. 
• Tax-free withdrawals: Any withdrawal for a qualified medical expense is not subject to federal income tax. 

Are HSA Contributions Tax*Deductible? 

Yes, HSA contributions are tax-deductible, but how you receive the tax break depends on how the contribution is made. Direct contributions are made post-tax, and a payroll contribution is made pre-tax. 

• Direct contribution: You move money from your personal bank account to your HSA. These are post-tax contributions. You aren’t required to itemize to receive the tax break. 
• Payroll contribution:, If your employer deducts the amount from your paycheck to contribute to your HSA, it’s considered a pre-tax contribution. You cannot deduct this amount on your tax return because this amount was not included in your taxable income. 

2026 HSA Contribution Limits 

There are updated contribution limits in 2026. 

How to Claim the HSA Deduction 

There are a couple of things you need to do to claim your HSA deduction. You will need to fill out Form 8889. 

Form 8889 reports HSA contributions and withdrawals, and determines the HSA deduction. This form must be attached to your federal tax return. You will need to fill out all relevant parts, which may include Part 1 and Part II. 

Part I: HSA Contributions and Deductions:

• Line 2. Enter the total HSA contributions you made (excluding employer contributions). This can be found on Form 5498-SA.
• Line 3. Enter the maximum allowable contribution for your coverage (self-only or family). 
• Line 9. Enter the contributions made by your employer (found on Form W-2 in Box 12).
• Line 13. Calculate your HSA deduction. This is the amount you contributed to your HSA, minus any employer contributions. The amount will be included as an “above-the-line” deduction on your tax return.

Part II: HSA Distributions

• Line 14a. Enter the total HSA distributions (withdrawals) during the tax year, found on Form 1099-SA.
• Line 15. Enter the amount of those withdrawals used for qualified medical expenses.
• Line 16. Report any non-qualified distributions, which may be subject to income tax and an additional 20% penalty.

Once you fill out Form 8889, you will need to transfer specific amounts to Schedule 1 and Form 1040. Here’s what you need to do: 

• Schedule 1, Line 13. Report the deduction amount from Form 8889, Line 13. This deduction decreases your taxable income.
• Form 1040, Line 2. If there were any taxable distributions from your HSA, it must be reported as income on your Form 1040.

Common Mistakes and Tax Traps 

You want to avoid common mistakes and tax traps when contributing to your HSA. Don’t make these missteps: 

1. Don’t put too much money in your HSA account. Be aware of the limits. If you put too much money in your HSA, the IRS will levy a 6% excise tax every year the amount remains in your account. 
2. Don’t make withdrawals for nonqualified expenses. Your HSA withdrawals are meant for qualified medical withdrawals. A qualified withdrawal doesn’t include purchasing vitamins or a gym membership. If you’re under 65 and make a non-qualified withdrawal, the amount will be subject to income tax and a 20% penalty. If you’re over 65, the amount will be subject to income tax but no penalty. 
3. Don’t assume all contributions are created equal. If you directly contribute, you save on your federal income tax, but you’re still responsible for Social Security and Medicare taxes. A contribution made by your employer is done before FICA taxes are calculated. 

HSA Planning Strategies for 2026 

As you consider HSA strategies for 2026, here are a few pointers: 

1. Timing. You have until April 15, 2027, to make HSA contributions for 2026. 
2. HSA Approach. If you have out-of-pocket money available to spend on your health needs, use those funds first. It is a good idea to continue to let your HSA funds grow. 
3. State Rules. Different states treat HSA contributions differently. In California, HSA contributions are now considered non-taxable. Check your state laws to make sure you’re not making assumptions about taxes. 

In Summary: HSAs and Taxes

Here are some key takeaways you should keep in mind: 

• Contribute up to the IRS limit: Make sure you contribute the maximum allowed by the IRS. For individuals it is $4,400 and $8,750 for families. Those who are 55 and older can add an additional $1,000 as a catch-up contribution. 
• Take advantage of employer contributions: If your employer contributes $1,500, you can contribute $2,900 to max out the contribution limit. 
• Contribute through pre-tax payroll deductions: Set up automatic contributions through your payroll deductions. These contributions are exempt from federal income tax, Social Security and Medicare taxes.
• Invest: Once your account reaches a certain limit, you should invest the funds in stocks, mutual funds and other investments. You can take advantage of tax-free growth.
• Contribute after-tax funds: If you’re unable to contribute through your payroll, you can still make after-tax contributions to your HSA. These contributions are tax-deductible. 
• Check limits: Make sure you check contribution limits every year.
