The HSA contribution limits for 2027 are already published by the IRS. The limit depends on self-only or family high-deductible health plan coverage, while eligibility depends on more than the deductible printed on an insurance card.
Employer deposits and your own deposits share the same annual limit. Contributing too much can create tax reporting and correction work, so calculate the remaining room before making a year-end deposit.
Key answer: The 2027 HSA contribution limit is $4,500 for self-only coverage and $9,000 for family coverage. An eligible person age 55 or older by year-end can generally add a $1,000 catch-up contribution. Employer contributions count toward these totals.

2027 contribution and HDHP limits
| 2027 item | Self-only | Family |
|---|---|---|
| HSA contribution limit | $4,500 | $9,000 |
| Minimum HDHP deductible | $1,750 | $3,500 |
| Maximum HDHP out-of-pocket expenses | $8,700 | $17,400 |
The out-of-pocket figures exclude premiums. The IRS also published 2027 limits for qualifying direct primary care service arrangements: aggregate monthly fees generally cannot exceed $150 for one person or $300 when the arrangement covers more than one person for the special HSA rule to apply.
Who is eligible to contribute
In general, you must be covered by an HSA-eligible high-deductible health plan on the relevant date, have no disqualifying other health coverage, not be enrolled in Medicare, and not be claimable as another person's tax dependent.
An insurance plan calling itself “high deductible” is not enough. Confirm that the plan is HSA-compatible. Beginning in 2026, federal law also treats qualifying Bronze and Catastrophic Exchange plans as HSA-compatible under the new rule described by the IRS, but personal eligibility can still be affected by other coverage.
Catch-up and spouse rules
The additional $1,000 catch-up is available to an eligible individual who is age 55 or older at the end of the tax year. Catch-up contributions are individual. If both spouses qualify for a catch-up, each spouse generally needs an HSA in that spouse's own name for the separate catch-up amount.
Married couples with family coverage share the family contribution limit. They can divide regular family contributions between their HSAs, but combined regular contributions cannot exceed the family limit.
Contribution deadline and monthly eligibility
HSA contributions for a tax year can generally be made through the due date of that year's federal income tax return, without extensions. Tell the HSA custodian which tax year a contribution is for when contributing after December 31.
Your permitted amount may be lower when you are eligible for only part of the year. The last-month rule can allow a full-year contribution in some circumstances, but it includes a testing period. Losing eligibility during that period can make part of the contribution taxable and may add an extra tax. Use Form 8889 instructions or tax advice for a midyear change.
How to prevent excess contributions
- Add employee payroll deposits, direct deposits, and employer deposits.
- Confirm whether coverage was self-only or family for each month.
- Include a catch-up only for an eligible account owner age 55 or older.
- Subtract the total already contributed from the applicable limit.
- If an excess occurred, contact the HSA custodian before the tax filing deadline about a corrective distribution.
Do not treat a rollover from another HSA as a new annual contribution when it is completed correctly. A one-time qualified HSA funding distribution from an IRA has separate rules and generally counts toward the annual limit.
Frequently asked questions
Do employer contributions count?
Yes. Employer and employee contributions count together toward the annual limit.
Can I contribute after enrolling in Medicare?
Generally no for months of Medicare enrollment. Retroactive Medicare coverage can affect the correct stopping date, so plan contributions carefully before enrollment.
Can spouses put both catch-ups in one HSA?
No. Each eligible spouse's catch-up generally must go into an HSA owned by that spouse.
Is the HSA balance forfeited at year-end?
No. An HSA balance remains in the account and is portable; it is different from a health FSA.

Final checklist
Use $4,500 or $9,000 as the 2027 starting limit, add an eligible $1,000 catch-up, and subtract every employer and employee contribution. Confirm HSA eligibility month by month before relying on the maximum.
