What Is an HSA?
A Health Savings Account (HSA) is a tax-advantaged account available to anyone enrolled in a qualifying High Deductible Health Plan (HDHP). Unlike an FSA, HSA balances roll over indefinitely and stay with you if you change jobs or health plans — there's no "use it or lose it" deadline, and the account can even function as a supplemental retirement fund once you turn 65.
2027 HSA Contribution Limits (Projected)
| Coverage Type | 2027 Projected | 2027 With Catch-Up (55+) | 2026 Confirmed |
|---|---|---|---|
| Self-Only | ~$4,550 | ~$5,550 | $4,400 |
| Family | ~$9,000 | ~$10,000 | $8,750 |
The $1,000 catch-up contribution for age 55+ is set by statute and has not been indexed for inflation since 2004. It remains at $1,000 for 2027.
2027 HDHP Requirements (Projected)
| Requirement | Self-Only (2027 Proj.) | Family (2027 Proj.) | 2026 Confirmed |
|---|---|---|---|
| Minimum Annual Deductible | ~$1,750 | ~$3,500 | $1,700 / $3,400 |
| Maximum Out-of-Pocket | ~$8,750 | ~$17,500 | $8,500 / $17,000 |

Key Dates & Deadlines
Contribution deadline: You have until the federal tax filing deadline — projected April 15, 2028 — to make HSA contributions for the 2027 tax year, the same deadline as IRA contributions.
Payroll vs. direct contributions: Contributions made through payroll deduction avoid both income tax and FICA tax, while direct contributions to your HSA provider are only income-tax deductible (claimed on Schedule 1). Both count toward the same annual limit.
Medicare cutoff: HSA eligibility ends the month you enroll in any part of Medicare. Many people delay Medicare Part A enrollment past age 65 specifically to keep contributing to an HSA — but this requires also delaying Social Security benefits, since claiming Social Security after 65 triggers automatic, retroactive Part A enrollment.
How HSA Eligibility Works in 2027
HDHP definition gates HSA contributions: An HSA can only receive contributions in months you're covered by a qualifying High Deductible Health Plan. The IRS requires the HDHP to have a minimum annual deductible (projected ~$1,750 self-only / ~$3,500 family for 2027) AND an out-of-pocket maximum at or below the published ceiling (projected ~$8,750 / ~$17,500). A plan that meets the deductible but exceeds the out-of-pocket cap disqualifies HSA eligibility for that month, even if the rest of the year qualified.
Age 55 catch-up and married-couple splits: The $1,000 catch-up contribution applies to each spouse age 55+ separately, but only when the catch-up amount is contributed to that spouse's own HSA. Two married 55+ partners on a family HDHP can each open an HSA and each contribute $1,000 catch-up, for $2,000 combined; if only one HSA exists, only one $1,000 catch-up is allowed even though both spouses are eligible. The base family contribution itself can be split between the two HSAs in any ratio.
Last-month rule and the 13-month testing period: Workers who become HSA-eligible mid-year can elect the "last-month rule" to contribute the full annual limit if they have HDHP coverage on December 1. The catch: they must remain HSA-eligible through the entire following calendar year (the testing period). Breaking eligibility during the testing period — by switching to non-HDHP coverage or losing coverage — triggers ordinary-income tax plus a 10% penalty on the disallowed portion.

Frequently Asked Questions
What are the projected 2027 HSA contribution limits?
Applying a projected ~3% inflation adjustment to the confirmed 2026 amounts, the 2027 HSA contribution limit is estimated at approximately $4,550 for self-only coverage and $9,000 for family coverage. These figures are estimates — the IRS typically announces official HSA limits each May, roughly 18 months ahead of the tax year they apply to.
Does the $1,000 catch-up contribution increase for 2027?
No. The $1,000 catch-up contribution for HSA owners age 55 and older is fixed by statute and has not been indexed for inflation since it was introduced in 2004. It remains $1,000 for 2027 regardless of how the base contribution limits are adjusted.
What HDHP deductible and out-of-pocket limits qualify for HSA eligibility in 2027?
Projected 2027 figures put the minimum annual HDHP deductible at approximately $1,750 self-only or $3,500 family, with a maximum out-of-pocket limit of approximately $8,750 self-only or $17,500 family. A plan must meet both the minimum deductible and the out-of-pocket ceiling to qualify as HSA-eligible.
Can I still contribute to an HSA once I enroll in Medicare?
No. Enrolling in any part of Medicare, including Part A, ends HSA contribution eligibility because Medicare is not a High Deductible Health Plan. You should stop new contributions the month Medicare coverage begins to avoid an excess-contribution penalty, though funds already in the HSA remain available tax-free for qualified medical expenses indefinitely.
