How to how to set up a health savings account (2026) | HSA

Your health insurance plan must meet specific IRS criteria to be considered an HSA-eligible HDHP. For 2026, this means your plan's minimum deductible must be at least $1,700 for self-only coverage or $3,400 for family coverage. Additionally, your plan's maximum out-of-pocket expenses (including deductibles, co-payments, and co-insurance, but excluding premiums) cannot exceed $8,500 for self-only

Beyond having an HDHP, you cannot be covered by any other non-HDHP health insurance plan, including Medicare, TRICARE, or a spouse's general-purpose Flexible Spending Account (FSA). The only exception is a Limited-Purpose FSA (LPFSA) which only covers dental and vision expenses. If you are enrolled in Medicare, even if you still have an HDHP, you are no longer eligible to contribute to an HSA.

To contribute to your own HSA, you cannot be claimed as a dependent on someone else's tax return. This rule applies regardless of your age or whether you meet the HDHP and other coverage requirements. If you are claimed as a dependent, you are not eligible to open or contribute to an HSA.

Many financial institutions and specialized HSA administrators offer accounts. Popular choices include Fidelity, Optum Bank, and HSA Bank. Your employer may have a preferred provider, often integrated directly with payroll deductions, but you can typically open an HSA with any eligible provider.

Provider fees can eat into your savings. Fidelity is notable for offering 0% fees on investments with any balance and no monthly account fee. In contrast, Optum Bank often charges $2.50-$4.50 per month, while HSA Bank charges $3.50 per month (waivable with a $3,000+ balance). Beyond monthly fees, scrutinize investment options and their associated expense ratios, which typically average 0.5-1%.

If you plan to use your HSA as an investment vehicle for retirement healthcare, prioritize providers with a wide range of low-cost investment options, such as ETFs and index funds. Some providers require a minimum cash balance before allowing investments. If you anticipate frequent withdrawals, ensure the provider offers easy access to funds via a debit card or online transfers.

There are several ways to contribute to your HSA. If you're a W2 employee, the most advantageous method is typically through payroll deductions. These contributions are made pre-tax, meaning they reduce your gross income for federal (and often state) income tax purposes, as well as FICA taxes.

Carefully monitor your contributions to ensure you don't exceed the IRS-mandated limits for 2026. For self-only HDHP coverage, the maximum is $4,400, and for family HDHP coverage, it's $8,750. If you are age 55 or older and not on Medicare, you can contribute an additional $1,000 catch-up contribution.

You have until the tax filing deadline of the following year to make contributions for the current tax year. For 2026 contributions, the deadline is typically April 15, 2027. This flexibility allows you to make contributions based on your final healthcare expenses or income for the year, offering a valuable opportunity to reduce your taxable income even after the year has ended.

Unlike many other savings vehicles, an HSA allows your funds to grow tax-free. Many providers offer investment options, such as mutual funds or ETFs, for balances exceeding a certain threshold. If you have the financial capacity to pay for current medical expenses out-of-pocket, consider investing your HSA funds.

The 'triple tax-free' benefit means qualified withdrawals for eligible medical expenses are tax-free. However, it is your responsibility to prove that withdrawals were for eligible expenses in case of an IRS audit. Keep detailed records of all medical expenses, including receipts, Explanation of Benefits (EOBs) from your insurer, and doctor's notes.

An HSA is often called the 'ultimate retirement account' because its tax advantages become even more potent after age 65. At this point, you can withdraw funds for any purpose without penalty, though non-medical withdrawals will be subject to ordinary income tax (similar to a 401k or IRA). For qualified medical expenses, withdrawals remain tax-free regardless of age.
