2027 HSA Contribution Limits: $4,500 Self-Only, $9,000 Family

The IRS announced 2027 HSA contribution limits on May 29, 2026, via Revenue Procedure 2026-24, over a year before the 2027 tax year even begins. If you have a high-deductible health plan (HDHP), the numbers below are already final; there's no "wait for the official announcement" step the way there is with 401(k) and IRA limits.

2027 HSA Contribution Limits

The catch-up contribution is worth calling out specifically: it has stayed at $1,000 every year since HSAs allowed catch-up contributions began in 2009. Unlike the self-only and family limits, which the IRS adjusts annually for inflation, the $1,000 catch-up amount is fixed directly in the tax code. It only changes if Congress passes a new law, not through the IRS's routine inflation math.

So a self-only HDHP holder age 55 or older can contribute $5,500 total in 2027 ($4,500 + $1,000), and a family-coverage holder in the same age bracket can contribute $10,000 total ($9,000 + $1,000) if both spouses are HSA-eligible and each opens their own account for their own catch-up (a shared HSA can't hold both spouses' catch-up contributions; each 55+ spouse needs their own account for that portion).

Why HSA limits come out so much earlier than 401(k)/IRA limits

Retirement plan limits (401(k), IRA) and HSA limits are set by different parts of the tax code, on different schedules. 401(k) and IRA limits depend on inflation data through September, so the IRS typically can't confirm them until late October or early November. HSA limits use an earlier-arriving inflation measure, which is why Revenue Procedure 2026-24, covering HSA, HDHP, and HRA limits for 2027, was already out by the end of May 2026, months before anyone will see a confirmed 401(k) number.

Revenue Procedure 2026-24 also confirmed the 2027 HDHP thresholds that determine whether a health plan qualifies someone for HSA eligibility in the first place (minimum deductible and maximum out-of-pocket limits). Those numbers moved too, so it's worth checking your specific plan's terms for the new year rather than assuming this year's HDHP still qualifies.

What to do with this

If you already have an HSA-eligible HDHP, there's nothing to wait for. Set your 2027 contribution plan now:

• Maxing out is usually worth prioritizing. An HSA is the only account with a triple tax advantage: contributions are pre-tax (or tax-deductible), growth is tax-free, and withdrawals for qualified medical expenses are tax-free too, a better deal than either a 401(k) or a Roth IRA on their own.
• If you're 55 or older and married with both spouses HSA-eligible, confirm each spouse has their own HSA account open before year-end, since the $1,000 catch-up only applies per person, per account.
• Payroll HSA contributions typically need an election change, not an automatic rollover. Check with your employer's benefits portal once open enrollment opens, so your 2027 contribution actually reflects the new limit rather than defaulting to your 2026 election amount.

Quick answers

What is the 2027 HSA contribution limit? $4,500 for self-only HDHP coverage, $9,000 for family HDHP coverage, both confirmed by the IRS, not a projection.

Is the catch-up contribution changing? No. It stays at $1,000 for anyone 55 or older, the same fixed amount since 2009.

When do these limits take effect? January 1, 2027, for the 2027 tax year. The 2026 limits ($4,400 self-only, $8,750 family) still apply through the end of 2026.
