2026–2027 HSA Contribution Limits, HDHP Deductibles, and How to Make the Most of Your Health Savings Account

If I had to pick one tax-advantaged account most people are underusing, it would be the HSA — and it’s not particularly close.

I’ve been contributing to one for years, and the more I’ve learned about how these accounts work, the more I think of them as a stealth retirement account. Most people treat an HSA like a medical checking account — contribute a little, spend it on copays and prescriptions, and start fresh in January. That’s a completely valid approach, and you still come out ahead on taxes. But if you can afford to let the money sit and invest it, the HSA becomes something much more interesting.

Here’s the basic pitch: contributions go in pre-tax (lowering your taxable income), the money grows tax-free, and qualified medical withdrawals come out tax-free. That triple tax advantage doesn’t exist anywhere else in the tax code. A traditional 401(k) gives you a deduction now but taxes you on the way out. A Roth gives you tax-free growth but no deduction up front. The HSA does both — as long as you spend it on medical expenses, which, at some point in your life, you will.

The catch is that you have to be enrolled in a qualifying High Deductible Health Plan (HDHP) to contribute. That’s not the right fit for everyone, especially if you have ongoing medical costs that would eat through a high deductible every year. But for people who are generally healthy and can absorb the higher deductible, the math often works out favorably once you factor in the tax savings and the lower premiums that typically come with HDHPs.

Below are the confirmed 2026 and 2027 limits, updated HDHP thresholds, and everything you need to know about getting the most out of your HSA. The 2026 limits come from IRS Revenue Procedure 2025-19; the 2027 limits were confirmed in May 2026 via IRS Revenue Procedure 2026-24.

2026 and 2027 HSA Contribution Limits and HDHP Thresholds (Official)

The IRS released the 2027 figures earlier than some readers expect — HSA limits come out in a separate Revenue Procedure each May, well ahead of the October/November batch that covers 401(k)s, IRAs, and FSAs. That gives you a longer runway to plan HDHP elections and payroll HSA contributions for 2027 open enrollment.

Note for married couples where both spouses are on HDHP coverage through separate employers: each can contribute up to their individual plan’s share of the family limit, but the combined household total can’t exceed the family maximum ($8,750 in 2026, $9,000 in 2027). Coordinate with your spouse during open enrollment.

New for 2026: Direct Primary Care Memberships Are Now HSA-Compatible

This is a genuinely new wrinkle most HSA guides haven’t caught up on yet. The One Big Beautiful Bill (OBBB), passed in 2025, added a provision letting you belong to a Direct Primary Care (DPC) membership — the flat monthly-fee arrangement some primary care practices use instead of billing insurance — without losing HSA eligibility.

Under Revenue Procedure 2026-24, a DPC arrangement doesn’t count as disqualifying “other health coverage” as long as the fees stay at or under $150 per month for individual coverage or $300 per month if the membership covers more than one person. Those thresholds are effective for months beginning in 2026 and will be adjusted for inflation starting in 2027.

Before this change, many DPC memberships technically made you HSA-ineligible because the IRS treated them like a health plan. If you’re considering a DPC arrangement alongside an HDHP, this removes a real obstacle — just keep your membership fee under the monthly cap.

How HSA Accounts Work (The Basics)

A Health Savings Account is a tax-advantaged account you own — not your employer — that works alongside a High Deductible Health Plan. Contributions go in pre-tax, investments grow tax-free, and qualified medical withdrawals come out tax-free. That’s the triple tax advantage, and it’s genuinely exceptional compared to any other savings vehicle.

You can use HSA funds for qualified medical expenses at any time. What makes HSAs different from FSAs is that unused funds roll over indefinitely — there’s no annual forfeiture. An HSA you funded at 40 can still be paying for medical expenses at 70.

Contribution limits are prorated based on the months you’re enrolled in an eligible HDHP plan. If you switch mid-year, your annual maximum is reduced proportionally — though a “last-month rule” allows you to contribute the full year’s amount if you’re enrolled on December 1, provided you stay enrolled through the following 13 months.

High Deductible Health Plans (HDHP): What Qualifies

To contribute to an HSA, your health plan must meet the IRS definition of an HDHP:

Minimum deductible: $1,700 for individual, $3,400 for family in 2026, rising to $1,750 individual and $3,500 family in 2027. Your plan must have a deductible at least this high before insurance pays anything (except preventive care).

Maximum out-of-pocket limit: $8,500 for individual, $17,000 for family in 2026, rising to $8,700 individual and $17,400 family in 2027. Once you’ve spent this much in a plan year, the HDHP covers 100% of remaining costs.

Not all high-deductible plans qualify — your plan must meet both the minimum deductible and stay under the OOP maximum. Check with your HR department or insurer to confirm your plan is HSA-eligible before contributing.

The Triple Tax Advantage — and Why I Don’t Touch My HSA

I’ve been contributing to an HSA for years, and the strategy I’ve landed on is simple: don’t spend it. I pay medical bills out of pocket and let the HSA grow invested in broad index funds.

Here’s why that works so well:

Tax 1 — Contributions are pre-tax. Contributions made through payroll deductions avoid federal income tax, FICA (Social Security and Medicare), and often state income tax. A $4,400 contribution from someone in the 22% bracket saves roughly $1,100 in federal income tax alone — plus another $337 in FICA.

Tax 2 — Investments grow tax-free. Once your balance exceeds a threshold (usually $1,000–$2,000 depending on the provider), you can invest HSA funds in mutual funds or ETFs. Capital gains, dividends, and interest compound without any annual tax drag.

Tax 3 — Qualified withdrawals are tax-free. Distributions for qualified medical expenses — which include a broad range of costs, from prescriptions to dental to vision — are completely tax-free at any age.

Example: HSA vs. Taxable Account Over 20 Years

Sarah, 45, contributes $4,400/year to her HSA and invests it in a broad index fund earning 7% annually. She pays all current medical costs out of pocket.

Over 20 years: roughly $180,000 in tax-free HSA assets, vs. approximately $145,000 in a taxable account making identical returns (assuming 22% bracket on dividends/gains each year). The gap widens the longer you don’t withdraw.

If she’s in the 24% bracket, the difference is even more pronounced.

Example: Maxing Out the New 2027 Family Limit

Marcus and Priya, married with family HDHP coverage, plan to max out their HSA at the new $9,000 family limit starting in 2027 — $250 more than the 2026 cap.

In the 24% federal bracket, that extra $250 saves them about $60 in additional federal income tax, plus roughly $19 in FICA, just from the limit increase alone. Small on its own, but it compounds every year they max out going forward.

HSA Withdrawal Rules After Age 65

After age 65, HSA rules shift meaningfully:

• Qualified medical expenses: still completely tax-free
• Any other purpose: taxed as ordinary income, like a traditional IRA — but no penalty

This effectively makes the HSA a second traditional IRA for retirement. The key difference: use it for medical expenses and you pay zero tax. For many retirees, healthcare costs in retirement are significant enough that a large HSA balance stays entirely tax-free.

One important use after 65: HSA funds can pay Medicare Part B premiums, Part D premiums, and Medicare Advantage premiums tax-free. These are often excluded from other retirement accounts’ qualified medical expense definitions. That’s a meaningful advantage.

Common Issues to Watch Out For

1. Contributing while enrolled in Medicare. Once you enroll in Medicare (Part A, B, or otherwise), you’re no longer eligible to contribute to an HSA — even if you still have HDHP coverage through a spouse or employer. The enrollment date matters, not when you first become eligible. A lot of people miss this and end up with excess contributions that carry a 6% excise tax per year until corrected.

2. Using HSA funds for non-qualified expenses before 65. Distributions for non-medical purposes before age 65 are subject to income tax plus a 20% penalty. This is steeper than the 10% early withdrawal penalty on IRAs. Don’t tap your HSA for non-medical needs before retirement.

3. Forgetting to invest HSA funds. Many HSA accounts default to a cash savings account earning near-zero interest. If your balance exceeds the minimum threshold, move the excess into investment options. Cash sitting in an HSA is a missed opportunity.

4. Losing receipts for out-of-pocket medical expenses. The IRS has no statute of limitations on reimbursing qualified expenses paid out of pocket — as long as you have documentation that the expense occurred and you weren’t previously reimbursed for it. Keep records of every medical expense you pay out of pocket, even years before you plan to claim. You can reimburse yourself from the HSA years or even decades later.

5. Switching from HDHP to a PPO mid-year. If you contribute the full annual amount and then switch off an HDHP mid-year, you may have excess contributions. The IRS prorates based on months of eligibility. Correct excess contributions before the tax deadline to avoid the 6% excise tax.

Rolling Over HSA Accounts

When you change employers or switch HSA providers, you can roll over HSA funds. The rollover process works similarly to an IRA rollover — direct trustee-to-trustee transfers are the cleanest approach. You get one rollover per 12-month period if you receive the funds yourself (the 60-day rollover rule applies); direct transfers between trustees are unlimited.

Major providers like Fidelity now offer self-directed HSA plans with access to broad fund menus and low fees. I’ve moved my HSA to a lower-fee provider before — the transfer takes a week or two, and you’ll need to reselect your investments, but it’s worth it if your current provider has high fees.

HSA vs. FSA: The Key Difference

The biggest practical difference between an HSA and a Flexible Spending Account (FSA) is carryover. FSA funds expire annually (with limited carryover or grace period options). HSA funds roll over indefinitely and are yours even if you leave your employer.

If you have access to an HDHP with HSA, the long-term math almost always favors the HSA — especially if you can afford to pay current medical costs out of pocket and let the HSA compound.

Looking Ahead: 2028

The IRS hasn’t released 2028 HSA figures yet — those typically come out next May, in a Revenue Procedure similar to the one that just confirmed 2027. Based on the roughly 2.3–2.9% increases we saw from 2026 to 2027, here’s a rough projection:

These are estimates based on recent inflation trends, not official numbers — I’ll update this section as soon as the IRS confirms 2028 figures, likely in May 2027. The $1,000 catch-up contribution is fixed by statute and won’t move unless Congress changes it.

One often-overlooked benefit: HSA contributions made through payroll reduce your W-2 income, which can lower your AGI enough to qualify for (or increase) the Saver’s Credit — a dollar-for-dollar tax credit worth up to $1,000 ($2,000 for married filers) for lower-to-middle income savers.
