Learn HSA eligibility, 2026 contribution limits, qualified medical withdrawals, Form 8889 reporting, and California's different tax treatment.
A Health Savings Account, or HSA, is an individually owned tax-advantaged account for eligible people to save and pay qualified medical expenses. Federal contributions may be deductible or excluded from income, earnings are not taxed currently, and qualified medical distributions can be tax-free. California does not conform to the federal HSA rules.
An HSA is not the health insurance itself. Eligibility to contribute depends on the person's coverage and other facts, while existing HSA money remains available after eligibility ends.
For a month, an individual generally must have qualifying high-deductible health plan coverage, have no disqualifying other health coverage, not be enrolled in Medicare, and not be claimable as someone else's dependent. A general-purpose health FSA or HRA can make a person ineligible, including coverage through a spouse, while limited-purpose or post-deductible arrangements may be compatible.
Beginning in 2026, qualifying bronze and catastrophic health plans are treated as HSA-compatible under new federal rules, including eligible plans purchased outside an Exchange. Certain direct primary care arrangements also no longer disqualify an otherwise eligible person, and qualifying periodic direct-primary-care fees may be paid tax-free from the HSA within the governing limits. Telehealth relief is permanent for plan years beginning on or after January 1, 2025.
Coverage must still be reviewed rather than inferred from a plan's marketing label. Medicare enrollment generally ends HSA contribution eligibility, sometimes retroactively when Medicare enrollment is backdated.
For 2026, the federal HSA contribution limit is $4,400 for self-only coverage and $8,750 for family coverage. An eligible individual age 55 or older by year-end may contribute another $1,000. Spouses must each use their own HSA for their respective catch-up contributions.
The general 2026 HDHP minimum deductible is $1,700 for self-only coverage or $3,400 for family coverage. The maximum annual out-of-pocket amount is $8,500 for self-only coverage or $17,000 for family coverage. The newer bronze and catastrophic rule can qualify certain plans without satisfying the ordinary HDHP definition.
Employer, payroll, family-member, and personal contributions all count toward the annual limit. Eligibility for only part of the year can prorate the limit. The last-month rule may allow a full-year contribution when eligible on December 1, but failure to remain eligible through the testing period can create income and an additional tax.
Jordan has eligible family coverage throughout 2026 and is age 45. The family HSA limit is $8,750. Jordan's employer contributes $2,000, so no more than $6,750 of additional contributions can generally be made for Jordan without exceeding the limit.
If the $6,750 is contributed directly rather than through a cafeteria-plan payroll election, Jordan generally claims the federal HSA deduction on Form 8889 and Schedule 1. If it is made through qualifying pretax payroll, it is generally excluded from Form W-2 federal wages and is not deducted again on the return.
California does not allow the federal HSA deduction. Payroll treatment can also create California wage and basis differences requiring careful reconciliation.
HSA distributions are federally tax-free to the extent used to pay or reimburse qualified medical expenses incurred after the HSA was established for the account holder, spouse, or qualifying dependents. The expense cannot also be reimbursed by insurance or used for another tax benefit. Publication 502 and Publication 969 help identify eligible expenses, but insurance premiums are generally excluded except for specific categories.
There is generally no federal deadline to reimburse a qualifying post-establishment expense. A taxpayer who delays reimbursement should retain the receipt, proof of payment, insurance information, and proof that the expense was not previously reimbursed or deducted.
A nonqualified distribution is generally included in federal income and faces an additional 20% tax. The additional tax generally does not apply after the account holder reaches age 65, dies, or becomes disabled, although the nonqualified distribution remains taxable.
Form 8889 reports HSA contributions, calculates the deduction, reports distributions, and determines taxable amounts and additional tax. Form 1099-SA reports distributions; Form 5498-SA reports contributions and account information. The taxpayer — not the custodian — substantiates qualified medical use.
Excess contributions can face a 6% excise tax for each year they remain. Removing an excess and attributable earnings by the applicable deadline can change the result, so it should be coordinated with the custodian and return preparer.
An HSA belongs to the individual, is portable, and generally carries its balance forward indefinitely. A health FSA is an employer arrangement subject to plan-year reimbursement and carryover or grace-period rules. HSA funds can often be invested; FSA funds are generally reimbursement balances. Having a general-purpose FSA can also prevent HSA contributions.
California does not recognize HSAs. A federal HSA deduction is generally added back on Schedule CA, employer contributions excluded federally may require a California adjustment, and interest, dividends, and gains inside the account can be currently taxable by California. Because trades may not produce ordinary brokerage tax forms, California taxpayers need detailed annual HSA investment records.
California generally subtracts a federally taxable nonqualified HSA distribution to avoid taxing the same principal again under its nonconforming system, but account history and earnings matter. Use the current Schedule CA instructions rather than making a blanket adjustment.
Heath Income Tax can help reconcile HSA contributions and distributions and maintain separate California account records.
Can I spend HSA money after I leave my job?
Yes. The HSA is portable and remains yours regardless of employment status.
Must I be eligible when I take a distribution?
No. Contribution eligibility and distribution eligibility are separate. You can take qualified distributions at any time after the account is established.
Can I use an HSA for Medicare premiums?
Certain Medicare and other premiums can qualify under special rules, but Medigap premiums generally do not.
