HSA on H-1B or OPT: can you open one, deduct it, and keep it if you leave the US?

How much can you put in an HSA for 2027?

For 2027 the limit is $4,500 with self-only HDHP cover and $9,000 with family cover, and your employer's deposits count toward it. From age 55 you may add $1,000 a year.

Three changes in the One Big Beautiful Bill Act widen who qualifies (IR-2025-119):

• Telehealth before the deductible no longer breaks eligibility, for plan years from 2025.
• Bronze and catastrophic plans count as HSA-compatible from 2026.
• From 2026, certain direct primary care arrangements are allowed, and the HSA can pay their fees. For 2027 the fees must be no more than $150 a month ($300 for more than one person).

Moving from a health FSA to an HSA? A general-purpose FSA grace period running into 2027 blocks HSA contributions, unless your FSA balance at the end of the 2026 plan year is zero (Pub 969).

Is HSA money pre-tax for a nonresident alien?

Money taken from your pay through your employer's cafeteria plan is federally pre-tax for every employee, nonresident aliens included. Publication 15 (2026) says such contributions are not wages and are not subject to employment taxes or withholding.

Neither publication draws a line by visa, and the money never reaches W-2 box 1, so you claim nothing to get the saving. Some websites say a nonresident "cannot deduct" HSA contributions; that mixes up two routes.

Money you deposit yourself is the unsettled route. HSA money taken from pay outside a cafeteria plan is taxed as wages (Pub 15), so it needs the same deduction. The texts point two ways:

• The 2025 Instructions for Form 1040-NR include the HSA deduction (Schedule 1 line 13), and Pub 969 says to report it on "Form 1040, 1040-SR, or 1040-NR."
• Publication 519 (2025) says nonresident aliens "can generally claim only deductions related to income that is effectively connected" with a US business. Its list of deductions does not mention HSAs.

No IRS text we found says plainly whether a nonresident alien may take that deduction. The cafeteria-plan route has a clear answer; before a direct deposit, ask a tax preparer.

The pre-tax benefits comparison sets an HSA beside the other pre-tax elections. For your own paycheck, the take-home calculator models an HSA too.

Any year money goes into or out of your HSA, you file Form 8889. The 2025 Form 8889 instructions require it if "You, your employer, or someone else made contributions to your HSA." Payroll contributions appear in W-2 box 12, code W.

Can a J-1 use an HSA?

A J-1 exchange visitor usually cannot pair the required insurance with an HSA. 22 CFR 62.14 caps a J-1's deductible at $500 per accident or illness, while a 2027 HDHP's must be at least $1,750 for self-only cover.

A separate J-1 policy held beside an HDHP would usually be other health coverage, which ends HSA eligibility. The rule also asks for $50,000 of medical evacuation and $25,000 of repatriation cover, which an employer plan may not include.

Do states tax HSA money?

California does not follow the federal HSA rules, and New Jersey does not follow the federal cafeteria-plan rule. Other states were not checked for this guide.

• California's 2025 Schedule CA (540) instructions say "California law does not conform" to the HSA deduction. An employer's HSA contribution (W-2 box 12, code W) is added back, and "Interest or earnings in an HSA are taxable in the year earned." A non-medical payout taxed federally is "not taxable for California purposes."
• New Jersey "does not adopt the federal income tax treatment of cafeteria plans" (TB-39(R)), so benefits bought by salary reduction are New Jersey wages. The bulletin does not name HSAs; check how your employer reports yours.

What happens to your HSA if you leave the US?

The account stays yours: Pub 969 says an HSA is "portable" and "stays with you if you change employers or leave the work force." You do not have to take money out each year.

Only expenses incurred after you open the HSA qualify. For drugs bought abroad, Publication 502 says a prescribed drug bought and used in another country counts only if it is legal there and in the US.

How the US taxes a non-medical payout to someone who has left has no IRS text we found, whether on its rate, its source or a treaty. How your home country treats an HSA is outside this guide. Ask a tax preparer before you take money out for anything but medical care.

The last-month rule can cost you if you leave soon after joining. If you are eligible on December 1, you may fund the full year.

You must then stay eligible through December 31 of the next year. If you do not, for any reason but death or disability, the extra is added to your income with a 10% additional tax (Pub 969).

After an H-1B layoff, HSA money may pay COBRA premiums (Pub 969). The H-1B leaving-the-US guide covers your final return, and the retirement accounts guide covers a 401(k) and IRA.

Can you still put money in for 2026?

You can add money for 2026 until Thursday, April 15, 2027, if you were eligible in 2026 (Pub 969). It goes in outside payroll, so it saves no FICA, and for a nonresident alien the deduction is the unsettled point above.

What to do next

1. At open enrollment for 2027, check whether your plan is an HDHP: a deductible of at least $1,750 self-only or $3,500 family.
2. Check for other coverage on the first of each month: a general-purpose health FSA, an overlapping student plan, or a J-1's required policy.
3. If you choose an HDHP and an HSA, set the amount through your employer's cafeteria plan if it has one. The 2027 limit, $4,500 or $9,000, includes your employer's deposits. You can generally change it later for future paychecks.
4. If you join partway through 2027 and may leave the US or the plan before December 31, 2028, weigh the last-month rule first.
5. Keep your receipts and the forms your HSA provider sends (Form 5498-SA for money in, Form 1099-SA for money out). File Form 8889 for any year money goes in or out.
6. Read the open enrollment checklist for OPT and H-1B and why Marketplace subsidies end for visa holders in 2027.

F1TaxReturn prepares Form 1040-NR and Form 8843 for nonresident alien students for free, once the IRS publishes the final 2026 forms; you print, sign and mail them. It does not prepare Form 8889, or the Form 1040 an H-1B resident files.
