The IRS Just Announced 2027 HSA Limits. Here's Why That Matters for a Decision You're Making This Fall.

What the IRS Just Announced

On May 29, 2026, the IRS released Revenue Procedure 2026-24, setting 2027 contribution limits for Health Savings Accounts (HSAs) — tax-advantaged accounts available to people enrolled in a qualifying high-deductible health plan. Self-only coverage gets a $4,500 annual limit, up $100 from $4,400 in 2026. Family coverage gets $9,000, up $250 from $8,750. The age-55-and-older catch-up contribution stays at $1,000 — that figure is fixed by statute, not adjusted for inflation like the base limits are — bringing 2027 totals to $5,500 (self-only) and $10,000 (family) for anyone eligible for the catch-up.

The IRS also set the 2027 thresholds that determine HSA eligibility in the first place: a High-Deductible Health Plan (HDHP) must have a minimum deductible of $1,750 (self-only) or $3,500 (family), and a maximum out-of-pocket limit of $8,700 (self-only) or $17,400 (family). All of these figures take effect January 1, 2027.

That's a roughly 2.3% increase for self-only coverage and 2.9% for family coverage — smaller increases than some recent years, reflecting cooling inflation adjustments.

Why This Matters Now: Open Enrollment Happens This Fall

Here's the part that makes this worth reading now rather than filing away for New Year's: most employers run open enrollment for next year's health coverage in the fall, typically several weeks in October or November, ahead of a January 1 start date. That means the choice that determines whether you can actually use the new 2027 HSA limit — whether you enroll in a qualifying HDHP for 2027 — gets made just a few months from today, not next January. Wait until January to think about this, and the decision that matters most will already be behind you.

The HSA's Underrated Feature: Triple Tax Advantage

An HSA is one of the only savings vehicles in the U.S. tax code with three tax benefits stacked on top of each other: contributions are deductible (or pre-tax through payroll), the money grows tax-free while invested inside the account, and withdrawals for qualified medical expenses are also tax-free. No dollar in an HSA is taxed at any of the three stages, as long as it's eventually spent on qualified medical costs.

There's a fourth wrinkle worth knowing if you're thinking about an HSA as a long-term savings vehicle, not just a way to pay this year's copays: after age 65, you can withdraw HSA funds for any purpose, not just medical expenses. Non-medical withdrawals after 65 owe ordinary income tax — but unlike an earlier withdrawal, they don't carry the usual 20% penalty for non-qualified use. At that point, an HSA functions a lot like a traditional IRA, with the added benefit that medical withdrawals remain fully tax-free forever.

A New Wrinkle: Direct Primary Care No Longer Disqualifies You

One change worth flagging for anyone who pays a monthly membership fee for direct primary care — a subscription-style arrangement with a doctor's practice, separate from insurance: under the 2025 tax law that created several other provisions AskProsper has covered, a direct primary care membership no longer automatically disqualifies you from HSA eligibility, effective for 2026 onward. The fees have to stay under a cap — $150 a month for individual coverage, $300 a month for a plan covering more than one person — to preserve HSA eligibility. If you're paying for a direct primary care membership and assumed it ruled out an HSA, that assumption is now out of date.

What to Actually Do Before This Fall

A few concrete steps worth taking before open enrollment:

• Check whether your current or planned 2027 health plan actually qualifies as an HDHP under the deductible and out-of-pocket thresholds above — not every plan marketed as "high-deductible" clears the specific IRS bar.
• If you're eligible for the 55-and-older catch-up, make sure your contribution elections account for the full $5,500/$10,000 potential, not just the base limit.
• If you're already funding an HSA in 2026, remember this year's contribution deadline isn't until April 15, 2027 — there's no rush on the current year, but there's real value in deciding your 2027 coverage election with the new numbers already in hand rather than defaulting to whatever you picked last year.

One more mechanic worth knowing if you're newly HDHP-eligible partway through a year: the "last-month rule" lets you contribute the full annual limit for that year — not a prorated amount — as long as you stay HSA-eligible through December of the following year. Fall short of that "testing period" and the extra amount becomes taxable income plus a 10% penalty. It's a genuinely useful rule for someone switching plans mid-cycle, but it comes with a real tail risk if your coverage changes again before the testing period ends.

The Takeaway

A dollar-figure increase from $4,400 to $4,500 doesn't sound like breaking news on its own. What makes it worth a few minutes of attention is the timing: the decision that determines whether these new limits apply to you happens at open enrollment this fall, not next January, and an HSA's triple tax advantage is valuable enough that it's worth confirming your 2027 coverage actually qualifies before you're locked into a plan for the year.
