HSA limits 2027 are now official, and the timing matters more than the numbers. The IRS set the 2027 contribution limit at $4,500 for self-only coverage and $9,000 for family coverage, up from $4,400 and $8,750 this year. The figures have been final since May 29, 2026, when the IRS published Revenue Procedure 2026-24 — so unlike the 401(k) limits, there is nothing left to wait for.
The increase is modest — $100 for an individual, $250 for a family — but the decision that goes with it is not. Open enrollment for 2027 Marketplace coverage runs November 1, 2026 through January 15, 2027, and the plan you pick now decides whether you can open or keep funding an HSA next year.
What the 2027 numbers are
The full set from Revenue Procedure 2026-24: a high-deductible health plan must carry a minimum deductible of $1,750 for self-only coverage or $3,500 for family coverage, and cap total out-of-pocket costs at $8,700 or $17,400. Those are the tests a traditional plan must pass to be HSA-qualified.
If you are 55 or older by December 31, 2027, you can add a $1,000 catch-up contribution on top — taking the ceilings to $5,500 for self-only and $10,000 for family coverage. That $1,000 is fixed in the tax code and never rises with inflation, so do not expect it to move.
Employer and employee contributions count together toward the one limit. If you put in too much, the excess faces a 6% excise tax every year until you remove it, so it pays to check what your employer is already contributing before you set your own amount.
More plans now qualify
Here is the change many people will miss. Since January 1, 2026, bronze and catastrophic plans bought through the Marketplace count as HSA-compatible, even when their deductibles and out-of-pocket maximums do not pass the usual HDHP tests. The IRS confirmed this in Notice 2026-5, following the One Big Beautiful Bill Act.
That matters because bronze plans are usually the cheapest monthly premium on the Marketplace. A family that picked bronze mainly for the low premium can now pair it with an HSA — something that was not possible before 2026.
There is a second widening worth knowing about. Direct primary care arrangements — the monthly-fee doctor memberships — no longer disqualify you from an HSA, as long as the fees stay within $150 a month for an individual or $300 for a family. That change also took effect for months beginning after December 31, 2025.
Why an HSA is worth the paperwork
An HSA is the only account in the tax code with three layers of tax benefit: contributions are deductible, the money grows tax-free, and withdrawals for qualified medical expenses are tax-free too. A 401(k) gives you two of those; an HSA gives you all three.
It also belongs to you, not your employer. Change jobs and the balance follows you. And unlike a flexible spending account, the money never expires — there is no year-end deadline to spend it or lose it.
That last point is where people mix up the two accounts. The health FSA limit for 2027 is $3,500, with up to $700 carried over, and it is a separate limit from the HSA. Do not swap the numbers: $4,500 and $9,000 are the HSA figures.
The Medicare trap to plan around
One warning for anyone nearing 65. Once premium-free Medicare Part A starts, your HSA contribution limit drops to zero from that month — and Part A can be backdated up to six months. If you plan to claim Part A at 65, stop contributing about seven months before you apply, or you risk excess contributions and the 6% penalty.
You can still spend the HSA balance tax-free on medical costs after you go on Medicare, including Part B and Part D premiums. You just cannot add to it.

What to do this week
If you are choosing a 2027 plan during open enrollment, check whether it is HSA-qualified before you enroll — the plan documents will say so, and bronze and catastrophic Marketplace plans now qualify automatically. Our open enrollment guide explains the December 15 deadline for January 1 coverage: https://northchecknews.com/aca-open-enrollment-2027-december-15-deadline-premiums-13-percent/
Then set your contribution to spread across the year through payroll deduction, which also saves the payroll tax. And remember the 2026 limits are still open: contributions for 2026, capped at $4,400 and $8,750, can be made until April 15, 2027. The 2027 retirement-plan limits, by contrast, are still unannounced — see where the 401(k) and IRA figures stand: https://northchecknews.com/401k-ira-limits-2027-still-not-announced/
The 2027 tax brackets moved too, which changes how much a deductible HSA contribution is worth to you. The new standard deduction and brackets are here: https://northchecknews.com/irs-2027-tax-brackets-standard-deduction-16600-single-33200-joint/

Do I need a high-deductible health plan to have an HSA?
Yes, with one big exception: since January 1, 2026, bronze and catastrophic Marketplace plans count as HSA-compatible even if they do not pass the usual deductible and out-of-pocket tests.
Does the $1,000 catch-up rise with inflation?
No. It is fixed by statute in the tax code and stays at $1,000 every year.
Can I still contribute for 2026?
Yes. Contributions for 2026, capped at $4,400 self-only and $8,750 family, can be made until April 15, 2027.
What happens to my HSA when I go on Medicare?
Your contribution limit becomes $0 once premium-free Part A starts, and Part A can be backdated up to six months. Stop contributing about seven months before you apply for Part A. You can still spend the balance tax-free on qualified medical expenses.
