The HSA contribution limits for 2026 are 4,400 dollars for self only coverage and 8,750 dollars for family coverage, set by the IRS and indexed to inflation each year. If you are 55 or older, you can add a 1,000 dollar catch-up contribution on top. These are the most you can put into a Health Savings Account for the year, whether the money comes from you, your employer, or a mix of both. Michigan follows the federal rules, so the same annual HSA contribution limit applies here.

You can only contribute to an HSA if you are enrolled in a qualified high-deductible health plan (HDHP). For 2026, the HDHP must have a minimum deductible of at least 1,700 dollars for self only coverage or 3,400 dollars for family coverage. The plan’s out-of-pocket maximum cannot exceed 8,500 dollars for self only or 17,000 dollars for family coverage. If your health plan does not meet these HDHP thresholds, it is not HSA eligible, and you cannot make HSA contributions no matter how high the deductible feels.
Family coverage means your HDHP covers at least one person besides you, such as a spouse or child. If your plan covers only you, you use the self only limit. This matters because the family HSA contribution limit is nearly double the self only amount, so adding a dependent to an HSA eligible plan can roughly double how much you shelter from tax.
Once you turn 55, you can add a 1,000 dollar catch-up contribution each year for individuals age 55 or older until you enroll in Medicare. A special rule applies to married couples: each spouse who is 55 or older can make a full 1,000 dollar catch-up contribution, but the catch up must go into that spouse’s own HSA. So a couple who are both 55 plus can contribute the 8,750 dollar family limit plus 1,000 dollars in each of their two accounts.
Money your employer puts into your HSA counts against the same annual limit. If your employer contributes 1,000 dollars to your family HSA, you can add up to 7,750 dollars yourself to reach the 8,750 dollar cap. Payroll contributions through a cafeteria plan also avoid Social Security and Medicare tax, which is an extra advantage over contributing on your own and deducting it later.
You have until the federal tax filing deadline, usually April 15, 2027, to make 2026 HSA contributions. That means you can still fund last year’s HSA after the calendar year ends, which is useful if you have extra cash at tax time. Contributions you make on your own are an above the line deduction, so you get the tax break even if you do not itemize.
If you become HSA eligible partway through 2026, two rules apply. Under the pro-rata method, you contribute a fraction of the annual limit based on how many months you were eligible. Under the last month rule, if you are HSA eligible on December 1, 2026, you can contribute the full year’s limit, as long as you stay eligible through all of 2027. Break that testing period and the extra amount becomes taxable plus a penalty, so plan carefully.
Putting in more than the HSA contribution limit triggers a 6 percent excise tax on the excess each year it stays in the account. If you catch it, you can withdraw the excess contribution and any earnings before the tax deadline to avoid the penalty. This is why it helps to track employer contributions and your own together, especially if you switch jobs or plans mid year.
HSA eligibility has a few rules beyond owning a high deductible health plan. To be eligible for an HSA, you must be covered by a qualifying HDHP, not be enrolled in Medicare, and not be claimed as a dependent on someone else’s tax return. You also cannot be covered by a general-purpose health care flexible spending account, since that spending account disqualifies you. Once you enroll in Medicare, you can no longer contribute to your HSA, though you can still use HSA funds you already saved. If you meet these tests, you are eligible to open an HSA and participate in an HSA for the tax year.
The Internal Revenue Service adjusts HSA contribution limits, the HDHP limits, and the out-of-pocket limits for inflation from year to year, and publishes the maximum contribution amounts each spring for the following year. The 2026 rules for HSAs raised both the self-only and family maximum contribution limit and the HDHP thresholds. You can find the official figures in IRS Publication 969, which explains HSAs, the tax benefits, and how employee contributions and employer HSA contributions combine toward the annual contribution allowed. Because an HSA is a tax-advantaged savings account, contributing the maximum each year through payroll deductions is one of the best moves a saver can make.
An HSA is the only account with a triple tax advantage, contributions are pre-tax, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. Hitting the full HSA contribution limit for 2026, then investing what you do not spend, turns the account into a powerful way to save for future health care costs and retirement.
