HSA Contribution Limits 2027: $4,500 Self-Only, $9,000 Family, the $1,000 Catch-Up, and 2026 Limits

The 2027 HSA contribution limits are $4,500 for self-only coverage and $9,000 for family coverage, up $100 and $250 from 2026, according to IRS Revenue Procedure 2026-24. They cap what can go into a health savings account (HSA) paired with a high-deductible health plan (HDHP) for the year. Anyone who is 55 or older by December 31, 2027 adds a $1,000 catch-up, which lifts the ceilings to $5,500 and $10,000. For 2027 an HDHP needs a deductible of at least $1,750 (self-only) or $3,500 (family) and an out-of-pocket maximum no higher than $8,700 or $17,400, although bronze and catastrophic Marketplace plans now qualify whatever their numbers. Contributions for 2026, capped at $4,400 and $8,750, stay open until April 15, 2027.

Key takeaways:

2027 limits: $4,500 self-only, $9,000 family, plus $1,000 at age 55 or older; the catch-up is fixed in IRC §223(b)(3) and never rises with inflation
2026 limits: $4,400 and $8,750, and deposits for 2026 are accepted until April 15, 2027
Bronze and catastrophic Marketplace plans count as HDHPs from January 1, 2026, whatever their deductible or out-of-pocket maximum (One Big Beautiful Bill Act §71307)
Part-year coverage prorates the limit by the months you are covered on the 1st, unless you use the last-month rule and stay eligible through December 31, 2028
Self-employed: the deduction on Schedule 1, line 13 cuts income tax but not self-employment tax, and October 15, 2026 is the last day to pull out an excess 2025 contribution without the 6% excise tax

What Are the HSA Contribution Limits for 2027?

For 2027 you can put up to $4,500 into a health savings account with self-only HDHP coverage and up to $9,000 with family coverage. The limit covers every deposit made for the year combined: your own, your employer's, payroll deposits through a cafeteria plan, and money anyone else puts in for you. Rev. Proc. 2026-24 set the 2027 column below and Rev. Proc. 2025-19 the 2026 column, which matters until the April 15, 2027 deadline for 2026 contributions.

HSA and HDHP amount	2026	2027	Change
Contribution limit, self-only coverage	$4,400	$4,500	+$100
Contribution limit, family coverage	$8,750	$9,000	+$250
Catch-up contribution, age 55 or older	$1,000	$1,000	none
HDHP minimum deductible, self-only / family	$1,700 / $3,400	$1,750 / $3,500	+$50 / +$100
HDHP out-of-pocket maximum, self-only / family	$8,500 / $17,000	$8,700 / $17,400	+$200 / +$400
Direct primary care fees per month, one person / more than one	$150 / $300	$150 / $300	none
Excepted benefit health reimbursement arrangement (HRA), new money per plan year	$2,200	$2,250	+$50

HSA limits come out months before the fall inflation release that sets tax brackets. Section 223(g) of the Internal Revenue Code (IRC) measures inflation over the 12 months ending March 31, rounds each increase to a multiple of $50, and requires the IRS to publish the next year's amounts by June 1. That is why the IRS posted the 2027 numbers on May 29, 2026 (Internal Revenue Bulletin 2026-25 printed them on June 15), and why no 2028 figure is official until the IRS publishes one by June 1, 2027. For 2026 tax-savings math, the HSA contribution calculator runs the 2025 and 2026 limits.

How Much Can You Put in an HSA if You Are 55 or Older?

People who reach age 55 by December 31, 2027 can add a $1,000 HSA catch-up contribution for 2027, so the ceilings become $5,500 with self-only coverage and $10,000 with family coverage. The catch-up amount in IRC §223(b)(3) has been $1,000 since 2009 and is not indexed for inflation. It follows three rules:

It is personal. A married couple on family coverage where both spouses are 55 or older can reach $11,000, but each $1,000 must go into that spouse's own HSA; there are no joint HSAs (Publication 969).
It is prorated like the base limit when you are eligible for only part of the year: the worksheet for Form 8889, the HSA form filed with your return, adds it month by month.
It stops at Medicare. Your limit, catch-up included, is zero from the first month you are enrolled in Medicare.

How Is the 2027 HSA Limit Prorated for Part-Year HDHP Coverage?

With HDHP coverage for only part of 2027, your HSA limit is 1/12 of the annual amount for each month in which you were eligible on the first day of the month. Six months of self-only coverage starting July 1 gives $4,500 × 6 ÷ 12 = $2,250, or $2,750 with the catch-up, following the Line 3 Limitation Chart in the Form 8889 instructions.

The last-month rule is the exception. If you are HSA-eligible on December 1, 2027, IRC §223(b)(8) treats you as eligible for all 12 months with the coverage you had in December, so the full $4,500 or $9,000 (plus any catch-up) is available. The price is a testing period: you must stay eligible from December 1, 2027 through December 31, 2028. Lose eligibility in that window for any reason other than death or disability, and the amount you could not have contributed without the rule is added to your income for the year you lose eligibility, plus a 10% additional tax figured in Part III of Form 8889.

Can you deposit the whole year's amount in January? Yes, but the limit is still tested month by month when the year ends, so if your HDHP coverage stops in June, the part above your prorated limit becomes an excess contribution to withdraw.

Who Qualifies to Contribute to an HSA in 2027?

You can contribute to an HSA for any month in which, on the first day, you are covered by an HDHP, have no other health coverage that pays before the deductible, are not enrolled in Medicare, and cannot be claimed as someone else's dependent (Publication 969). Dental, vision, accident, disability, long-term care, and telehealth coverage do not count against you. A general-purpose health flexible spending arrangement (FSA) or HRA does disqualify you; a limited-purpose or post-deductible one does not. A family HDHP has one more test for 2027: any embedded per-person deductible must also be at least $3,500.

Bronze and Catastrophic Marketplace Plans Count as HDHPs

Since January 1, 2026, any bronze or catastrophic plan available as individual coverage through a Health Insurance Marketplace is an HDHP for HSA purposes, whatever its deductible and out-of-pocket maximum. Section 71307 of the One Big Beautiful Bill Act (OBBBA, Public Law 119-21) added this rule as IRC §223(c)(2)(H). Before it, many bronze plans failed on their out-of-pocket maximums, and catastrophic plans always failed because they must cover three primary care visits before the deductible. IRS Notice 2026-5, issued December 9, 2025, settles the edge cases:

A bronze or catastrophic plan bought off-Exchange counts if the same plan is available on an Exchange (Q&A-6).
Paying for the plan through an employer's individual coverage HRA does not spoil it (Q&A-5).
A bronze plan bought through a small employer's Small Business Health Options Program (SHOP) is group coverage, so it counts only if it passes the regular HDHP test (Q&A-8).
As the notice recaps, catastrophic plans are sold only to people under 30 or with a hardship exemption.

Open enrollment on HealthCare.gov for 2027 plans runs from November 1, 2026 to January 15, 2027; choose a plan by December 15 for coverage that starts January 1. State-run exchanges set their own dates. At tax time, the HSA deduction also lowers the modified adjusted gross income behind your premium tax credit on Form 8962, because that figure starts from AGI (IRC §36B(d)(2)(B)).

Direct Primary Care and Telehealth Before the Deductible

A direct primary care membership no longer blocks HSA contributions if the fees for all such arrangements stay at or below $150 a month for one person, or $300 when the arrangement covers more than one person; Rev. Proc. 2026-24 kept both figures for 2027. The arrangement must provide only primary care for a fixed periodic fee, with no procedures that need general anesthesia, no prescription drugs other than vaccines, and no lab work beyond what a primary care office normally does (IRC §223(c)(1)(E); Notice 2026-5). HSA money can pay the fees tax-free; fees above the cap can still be reimbursed, but they disqualify you from contributing for those months. Telehealth covered before the deductible is permanently allowed for plan years beginning after December 31, 2024 (OBBBA §71306).

Medicare Enrollment Ends HSA Contributions

Your HSA contribution limit drops to zero starting with the first month you are enrolled in Medicare, under IRC §223(b)(7). The trap is retroactive coverage. When you apply after 65, premium-free Part A can start up to six months before the month you apply, according to the Social Security Administration, and Publication 969 treats deposits made during that backdated period as excess contributions. Plan for it by treating the six months before your Medicare application as months with a zero limit.

Does an HSA Contribution Lower Self-Employment Tax?

No, not for a sole proprietor. The HSA deduction is an adjustment to income on Schedule 1 (Form 1040), line 13, while self-employment tax is computed on Schedule SE from the Schedule C profit on line 31, before any adjustments. The deduction cuts income tax only. Who deposits the money decides whether Social Security and Medicare tax is touched:

Who deposits the money	Income tax	Social Security and Medicare tax
You, from your own money	Deducted on Form 8889, then Schedule 1, line 13	No change; self-employment tax is figured on Schedule C profit
Your employer, or you through a cafeteria plan (payroll)	Excluded from wages; reported in W-2 box 12, code W	Not subject to Social Security or Medicare tax
An S corporation, for a 2% shareholder-employee	Included in W-2 box 1, then deducted on Form 8889	Not Social Security or Medicare wages if the plan meets IRC §3121(a)(2)(B)
A partnership, as a guaranteed payment	Included in the partner's income, then deducted on Form 8889	Counts as self-employment income on Schedule SE
A partnership, as a distribution	Not deductible by the partnership; the partner deducts it on Form 8889	Not self-employment income

The partnership and S corporation rows come from IRS Notice 2005-8. An S corporation deducts the contribution and includes it in box 1 of the owner's Form W-2, the owner deducts it on Form 8889, and it stays out of Social Security and Medicare wages when paid under a plan covering employees generally or a class of employees, the test in IRC §3121(a)(2)(B). Employees who contribute outside payroll get the income-tax deduction but still pay Social Security and Medicare tax on those wages (2026 Form W-2 instructions). Line-by-line reporting is in the Form 8889 guide to HSA contributions and distributions.

Worked Example: A Freelancer Who Moves to a Bronze Plan in July 2027

Leonie is 57 and single. She leaves a salaried job on June 30, 2027, when her employer's PPO coverage (not an HDHP) ends, and starts freelancing through a single-member LLC reported on Schedule C. Losing job-based coverage opens a special enrollment period, and the bronze plan she picks on HealthCare.gov starts July 1, making her HSA-eligible on the first of each month from July through December: six months.

Leonie's 2027 HSA	Proration	Last-month rule
Months treated as eligible	6 (July to December)	12
Base limit	$4,500 × 6 ÷ 12 = $2,250	$4,500
Catch-up (57 by December 31)	$1,000 × 6 ÷ 12 = $500	$1,000
2027 limit	$2,750	$5,500
Condition	None	HSA-eligible every month through December 31, 2028
Federal income tax saved at a 22% marginal rate	$605	$1,210

If Leonie contributes $5,500 and then takes a salaried job with a non-HDHP plan in March 2028, she fails the testing period. The $2,750 that only the last-month rule allowed is added to her 2028 income, and she owes a $275 additional tax (10%) on top. Contributing $2,750 carries no such risk. The inline tool above opens on her numbers.

Her self-employment tax is the same either way. On $60,000 of Schedule C profit for July to December, Schedule SE taxes $55,410 (92.35% of the profit) at 15.3%, or $8,478, whether she contributes nothing or $5,500, assuming her salary and profit together stay under the Social Security wage base. Her bronze premiums are a separate matter: HSA money cannot pay regular health insurance premiums, but premiums for her self-employed months go through the self-employed health insurance deduction.

Worked Example: An S Corporation Owner With Family Coverage

Soren, 47, is the only shareholder-employee of his S corporation. His spouse Noor is 56. Both are covered by a family HDHP for all of 2027 and have no other coverage, so they share one $9,000 family limit, plus Noor's $1,000 catch-up.

Deposit	Amount	Where it is reported
S corporation payroll deposits to Soren's HSA ($750 a month)	$9,000	Box 1 of Soren's W-2, not boxes 3 and 5 if the plan meets §3121(a)(2)(B); deducted on Soren's Form 8889
Noor's own deposit to her HSA	$1,000	Deducted on Noor's Form 8889
Household total	$10,000	The two Forms 8889 combine on Schedule 1, line 13

The split works because spouses may divide the family limit any way they agree, including nothing for one spouse (Form 8889 instructions, line 6). Noor's catch-up cannot sit in Soren's account, and a joint return still needs a separate Form 8889 for each spouse with an HSA. At a 24% marginal rate on their joint return, $10,000 of deductions saves $2,400 of federal income tax. Had each of them deposited $9,000 on the theory that each gets a family limit, $8,000 would be excess, owing a 6% excise tax of $480 for every year it stays in the accounts.

When Is the Deadline for 2026 and 2027 HSA Contributions?

HSA contributions for 2026 can be made until April 15, 2027, and contributions for 2027 until the due date of your 2027 return in April 2028. A filing extension does not extend either date (Form 8889 instructions). Tell the custodian which year a January-to-April deposit is for; an employer can make prior-year contributions in that window too, if it notifies you and the trustee.

October 15, 2026: Last Day to Remove an Excess 2025 Contribution

If you put more than your 2025 limit into an HSA ($4,300 self-only or $8,550 family, plus $1,000 at 55), you can still avoid the 6% excise tax. Withdraw the excess and its earnings by the due date of your 2025 return including extensions, which is October 15, 2026 for anyone who extended. If you filed on time without fixing it, the Form 5329 instructions give you the same date, six months after the original April 15 due date, under Treasury Regulation §301.9100-2, with an amended return marked "Filed pursuant to section 301.9100-2." The earnings are taxable in the year you withdraw them. Leave the excess in past October 15 and the 6% tax under IRC §4973 applies for 2025 and every later year it stays; the Form 5329 guide to excess contribution penalties covers Part VII, where it is computed.

What the 2027 HSA Limits Do Not Cover

The 2027 HSA limits of $4,500 and $9,000 cap deposits for the year and nothing else. They do not reach:

Rollovers and transfers. A trustee-to-trustee transfer between your HSAs, or one 60-day rollover in a 12-month period, does not count toward the limit. An IRA-to-HSA funding distribution, generally allowed once in a lifetime, does.
Balances and withdrawals. An HSA has no size cap, no use-it-or-lose-it rule, and no required withdrawals. Tax-free withdrawals only need records of qualified medical expenses incurred after the account was opened, so reimbursing yourself years later for bills you paid out of pocket is allowed; that is what most people mean by the "HSA loophole."
Other accounts. The 2027 health FSA limit comes separately in the IRS's fall inflation release (the 2026 figure is $3,400, Rev. Proc. 2025-32).
State income tax. California does not conform to the federal HSA deduction (Franchise Tax Board instructions for Schedule CA, line 13), and New Jersey's income tax does not allow it either; Assembly Bill A2634, which would change that, has sat in committee since January 13, 2026.
The rules OBBBA left alone. The One Big Beautiful Bill Act's three HSA sections, 71306 to 71308, changed which plans qualify. They did not raise the limits, index the catch-up, or allow contributions after Medicare enrollment.

Common HSA Contribution Mistakes for 2027

Giving each spouse a family limit. Married couples share one $9,000 family limit. Two $9,000 deposits leave $8,000 in excess even with one spouse's catch-up, and a 55-year-old spouse needs an HSA of their own to use the $1,000.
Forgetting payroll deposits. Employer contributions and your own cafeteria-plan deferrals, shown in W-2 box 12 with code W, use up the same $4,500 or $9,000 before you top up the account yourself.
Using the last-month rule before a job change. Contributing a full year's amount in December 2027 and then joining a non-HDHP employer plan in 2028 turns the extra into income plus a 10% additional tax.
Assuming every bronze plan counts. A bronze plan from a small employer's SHOP has to pass the regular $1,750 or $3,500 deductible test, and a direct primary care membership above $150 a month ($300 for more than one person) disqualifies you for those months.
Deducting the HSA on Schedule C. For a sole proprietor the contribution belongs on Form 8889 and Schedule 1, line 13. Working with small business owners at Anna Money and now at Jupid, we have seen this one often: the payment leaves the business account, so it gets booked as a business expense.

Personal Transfers Kept Off Your Schedule C: How Jupid Helps

Funding an HSA from a sole proprietor's business account is an owner draw, not a business expense, and your books should show it that way before anyone prepares a return. Jupid connects to your bank accounts and categorizes every transaction automatically, at 95.9% accuracy, so personal transfers are sorted apart from the deductible spending on your Schedule C. When a line looks off, or you want to know where the month's money went, ask the AI accountant in WhatsApp or iMessage and get the answer in real time from your own records. Try Jupid.
