Leaving the U.S. on an H-1B: What Happens to Your 401(k)?

Leaving the United States does not make your vested 401(k) disappear.

That sounds obvious, but it is one of the most persistent myths in H-1B communities. People preparing to move home are sometimes told that they must cash out their 401(k) before their visa expires or risk losing the money.

That is not how a 401(k) works.

Your vested retirement balance belongs to you. What changes when you leave your employer — and later the United States — is not ownership of the money. What changes are the plan rules, your investment options, your tax residency, withholding on future distributions, and possibly the tax treaty that applies to you.

Those distinctions matter because cashing out unnecessarily can turn a simple relocation into a large tax event.

The rule to remember

Your H-1B status and your 401(k) are separate. Leaving your job may make the account distributable, and leaving the United States may change your tax treatment, but neither event automatically takes away your vested retirement savings.

Verified: August 18, 2026. Retirement-plan terms, tax treaties, withholding rules, and brokerage policies can change.

What happens to your 401(k) when you leave your H-1B job?

The first event that matters is usually leaving your employer, not leaving the country.

Your own elective deferrals belong to you, together with the investment gains or losses attributable to those contributions.

Employer contributions can be different. Matching or nonelective employer contributions may be subject to the plan’s vesting schedule.

For example, suppose your account shows:

  • $60,000 from your own contributions and investment growth;
  • $20,000 from employer contributions; and
  • only 75% of those employer contributions are vested.

Leaving the company does not take away the $60,000 attributable to your vested account balance. But the unvested portion of the employer contribution can be forfeited under the plan’s rules.

That is why one of the smartest things to do before resigning is to download your vesting schedule and current vested-balance statement.

Your account may stay in the plan — but check the small-balance rule

Many former employees can leave their vested balance in the old employer’s plan, subject to the plan document.

Do not assume this automatically applies to every account, however.

Current federal rules allow plans, if their documents provide for it and the required procedures are followed, to automatically move certain small balances — now potentially up to $7,000 — into a Safe Harbor IRA when a former employee does not make another election.

So before you leave, ask the administrator:

  • Can I leave my balance in this plan after employment ends?
  • Does the plan have an involuntary distribution or automatic-rollover threshold?
  • Can the plan service a participant whose permanent address is outside the United States?
  • What happens to online access after my U.S. phone number or address changes?

The answer comes from your actual Summary Plan Description and plan administrator, not from a general H-1B article.

Leaving the U.S. does not automatically make you a nonresident alien that day

This is one of the most important corrections to make before discussing taxes.

Your immigration departure date and your federal income-tax residency ending date are not necessarily identical.

If you were a resident alien under the Substantial Presence Test, the IRS general rule can treat your residency as continuing through December 31 of your final year in the United States.

An earlier termination date may be available when the requirements are satisfied — including establishing a foreign tax home and a closer connection to that foreign country for the remainder of the year.

That means your departure year can become a dual-status tax year: resident alien for one part of the year and nonresident alien for another.

Why this matters

Do not tell your 401(k) administrator that you are a nonresident alien simply because your H-1B employment ended. Your tax documentation should reflect your actual federal tax status at the relevant time.

Your main choices after leaving the employer

Most departing H-1B workers will be deciding among three practical paths:

  1. Leave the vested balance in the former employer’s 401(k), if the plan permits it.
  2. Make a direct rollover to an eligible U.S. retirement account, commonly a Traditional IRA.
  3. Take a distribution.

There is no universal winner. The right choice depends on plan fees, investment options, future access from abroad, the custodian’s residency policies, your age, tax status, treaty position, and whether you actually need the cash.

Common 401(k) choices after leaving a U.S. employer
Choice Immediate U.S. tax Main advantage Main issue to check
Leave it in the 401(k) Generally none merely for leaving it invested No rollover required Plan fees, investment menu, foreign-address servicing, small-balance rules
Direct rollover to Traditional IRA Generally tax-deferred when properly completed Potentially more investment flexibility and account control Whether the IRA custodian will open and continue servicing the account after you live abroad
Take a cash distribution Taxable portion may be subject to U.S. income tax and withholding Immediate access to cash Income tax, possible 10% additional tax, treaty treatment, loss of tax-deferred growth

Why a direct rollover is different from cashing out

A properly completed rollover is fundamentally different from withdrawing the money for yourself.

With a direct rollover, the distribution moves directly from the qualified plan to an eligible retirement plan, such as a Traditional IRA.

Because the money is not paid to you as a normal taxable distribution, the rollover can preserve its tax-deferred status.

By contrast, if an eligible rollover distribution is paid to you first, the ordinary rollover rules generally give you 60 days to complete the rollover.

For a standard eligible rollover distribution paid directly to the participant, mandatory withholding rules can also apply. That can force you to replace the withheld amount with other cash if you want to roll over 100% of the distribution.

For most straightforward rollovers

If you have decided to roll the account over, ask the plan administrator and receiving custodian how to complete a direct trustee-to-trustee rollover. It usually creates fewer withholding and deadline problems than receiving the money personally.

Can you roll a 401(k) into your home country’s pension?

Do not assume that moving money from a 401(k) into a foreign retirement account is the same thing as a U.S. tax-free rollover.

U.S. rollover rules identify specific eligible retirement plans, including eligible U.S. qualified plans and IRAs.

A foreign retirement plan is not automatically an eligible rollover destination under those ordinary rules.

Therefore, withdrawing your 401(k), wiring the proceeds abroad, and depositing them into a Korean IRP, Indian retirement account, or another country’s pension arrangement should not be assumed to preserve U.S. rollover treatment.

A tax treaty may affect taxation of retirement benefits, but that is different from saying that the foreign account is automatically an eligible U.S. rollover destination.

If you become a nonresident alien, the withholding rule gets more complicated

This is where the simple statement “foreigners pay 30% on a 401(k)” becomes misleading.

The IRS says that a plan distribution paid to a foreign payee is generally subject to 30% withholding unless the payer can reliably associate the payment with valid documentation showing that the payee is a U.S. person or a foreign person entitled to a lower withholding rate.

Documentation may include Form W-8BEN, Form W-9, or other appropriate documentation depending on the situation.

But there is an important rule specifically for pensions and annuities.

The rule many summaries miss

IRS Publication 515 states that, in the absence of a treaty exemption, 30% withholding generally applies to the U.S.-source distribution. However, the payer may apply graduated withholding rates to the portion of a distribution arising from services performed in the United States after December 31, 1986.

This can be highly relevant to an H-1B worker whose retirement benefits arose from employment performed in the United States.

But do not turn it into another oversimplification.

It does not mean that every dollar of every H-1B 401(k) withdrawal is automatically subject to graduated rates. The character and source of the distribution, plan records, treaty rules, and withholding documentation can matter.

That is why the question to ask is not:

“Is the rate 30% or not?”

It is:

“How will this specific distribution be classified and withheld given my tax status, the source of the benefit, and my treaty?”

Withholding is not necessarily your final tax bill

The amount withheld when the distribution is paid and the amount of final U.S. tax you ultimately owe are not always identical.

If too much tax is withheld, an eligible nonresident taxpayer may be able to file Form 1040-NR and claim a refund based on the correct tax liability.

Likewise, too little withholding does not erase the underlying tax obligation.

This distinction matters enormously when comparing a 30% withholding number with the actual economic cost of taking a distribution.

How tax treaties change the answer

Many U.S. income-tax treaties contain articles dealing with private pensions and annuities.

Some can reduce or eliminate U.S. tax on qualifying pension payments to a resident of the treaty country.

But treaty language is not uniform.

IRS Publication 515 specifically warns that a treaty exemption for a pension or annuity may not apply to a lump-sum payment. Some treaties distinguish periodic pension payments from lump sums or other deferred compensation.

So this is not a question that should be answered with:

“My country has a U.S. tax treaty, so my 401(k) withdrawal is tax-free.”

You need to identify:

  • your treaty country of residence;
  • the pension or retirement article;
  • whether the payment is periodic or lump-sum;
  • whether the treaty’s saving clause affects you;
  • whether you satisfy the treaty’s residence requirements; and
  • which withholding certificate the payer requires.

What about the 10% early-distribution tax?

For many taxable distributions taken before age 59½, a 10% additional tax can apply on top of ordinary income tax.

But calling it an automatic 10% penalty for everyone under 59½ is also inaccurate because the Internal Revenue Code contains exceptions.

One particularly relevant 401(k) exception applies to certain distributions from a qualified employer plan after separation from service in or after the calendar year in which the participant reaches age 55.

That exception is associated with the employer plan. Rolling the money into an IRA and then withdrawing it can change which early-distribution exceptions are available.

Other exceptions exist as well.

Before rolling over if you are near age 55

Do not automatically roll the 401(k) into an IRA without checking the age-55 separation exception and your expected withdrawal needs. A rollover can be excellent for one person and remove a useful plan-specific withdrawal option for another.

Traditional 401(k) and Roth 401(k) need different rollover instructions

If your account contains only pretax Traditional 401(k) money, a direct rollover to a Traditional IRA is usually the straightforward tax-deferred path.

If you have a designated Roth 401(k), the treatment is different.

An eligible distribution from a designated Roth account can generally be directly rolled into a Roth IRA without including the Roth amount in income merely because of the rollover.

However, the five-year rules for qualified distributions from a Roth 401(k) and a Roth IRA are not identical.

Do not assume that the age of your Roth 401(k) automatically becomes the age of a brand-new Roth IRA in every respect.

If you are rolling a large Roth balance shortly before retirement, confirm the Roth IRA five-year rules before moving it.

And remember that rolling pretax Traditional 401(k) money into a Roth IRA is different: that is generally a Roth conversion, and previously untaxed amounts can become taxable in the year of conversion.

Can you open the IRA before moving abroad?

Possibly, and doing the identity verification while you genuinely live in the United States can be operationally easier.

But there is an important warning:

Opening an IRA before departure does not guarantee the brokerage will continue providing the same services after you become a resident of another country.

Brokerages can restrict trading, mutual-fund purchases, new contributions, or entire account relationships depending on the customer’s country of residence.

Before choosing a rollover custodian, ask:

  • Will you continue servicing my IRA after I move to my destination country?
  • Can I keep buying the investments I currently own?
  • Will any products become “sell only”?
  • Can I update the account to my real foreign address?
  • How will distributions to a foreign resident be handled?

Never keep a false U.S. residential address simply to avoid a broker’s international restrictions.

Our brokerage guide for non-residents and visa holders explains why residence-based eligibility matters.

The estate-tax issue deserves attention — but not a misleading shortcut

If you later become a nonresident who is not a U.S. citizen for estate-tax purposes, U.S. estate-tax rules can become relevant.

Estate-tax residence is based on domicile and is different from the resident-alien test used for federal income tax.

For an estate of a nonresident noncitizen, Form 706-NA can be required when relevant U.S.-situated assets and specified prior transfers exceed the $60,000 filing threshold.

But do not use that number to make this incorrect leap:

“My 401(k) is worth more than $60,000, therefore all of it is automatically subject to U.S. estate tax.”

The situs and treatment of retirement interests, annuities, securities, treaty provisions, beneficiary rights, and other assets can require a technical estate-tax analysis.

The practical lesson is simply this:

If your U.S. retirement and investment assets become substantial after you establish permanent residence abroad, add U.S. estate-tax planning to your cross-border checklist.

2026 retirement limits worth knowing before your final paycheck

If you are still employed and contributing before departure, the IRS increased several limits for 2026.

2026 limit Amount
401(k) elective deferral $24,500
General catch-up, age 50+ $8,000
Special catch-up, ages 60–63 $11,250
IRA contribution limit $7,500
IRA catch-up, age 50+ $1,100

Contribution eligibility and limits are separate issues from whether a rollover is permitted. A rollover does not count as a normal annual IRA contribution.

A practical departure checklist

Before your last day at work

  • Download your latest 401(k) statement.
  • Confirm your vested balance.
  • Download the Summary Plan Description.
  • Ask whether your balance can remain after separation.
  • Ask about the plan’s small-balance automatic-rollover rule.
  • Confirm your beneficiary designation.
  • Save the plan administrator’s international phone and mailing information.

Before choosing an IRA rollover

  • Confirm the custodian accepts your current application.
  • Tell the firm the country you expect to move to.
  • Ask whether it will continue servicing the IRA after the address change.
  • Check whether any securities or funds will become restricted.
  • If you decide to roll over, ask about a direct rollover.

After moving

  • Update the plan or custodian with your real address and tax status.
  • Provide the appropriate W-8 or W-9 documentation when requested.
  • Check the income-tax treaty for your new country of residence before taking a distribution.
  • If your departure year changes your tax residency, determine whether you have a dual-status filing requirement.
  • Before a large distribution, have the U.S. withholding treatment and home-country taxation reviewed together.

Frequently asked questions

Do I lose my 401(k) when my H-1B expires?

No. Expiration of H-1B status does not by itself take away your vested 401(k) balance. Your employer-plan rules determine what distribution options are available after employment ends, and small balances may be subject to automatic-rollover provisions.

Can I leave my 401(k) in the United States after moving home?

Often, yes, if the plan permits former employees with your balance to remain in the plan. Confirm the plan’s rules, fees, foreign-address procedures, and online-access requirements before leaving.

Should I roll my 401(k) into an IRA before leaving?

It can make sense if the IRA offers better investment choices, lower costs, or easier long-term administration. But first confirm that the custodian will continue serving you after you become resident in your destination country. Also consider whether keeping the employer plan preserves any withdrawal rule that may be useful to you, such as the age-55 separation exception.

Will a nonresident alien automatically pay 30% tax on a 401(k) withdrawal?

No single rate applies to every distribution. A foreign payee generally faces 30% withholding on a U.S.-source plan distribution unless valid documentation supports different treatment. IRS rules also allow graduated withholding on the portion of certain pension distributions attributable to services performed in the United States after December 31, 1986, and a tax treaty can further change the result.

If 30% is withheld, is that my final tax?

Not necessarily. Withholding is a collection mechanism. Your final U.S. tax liability may differ. If the amount withheld exceeds your actual liability, you may be able to claim a refund by filing the appropriate U.S. income-tax return, such as Form 1040-NR when applicable.

Can I transfer my 401(k) directly to a Korean IRP or another foreign pension?

Do not assume so. Ordinary U.S. tax-free rollover rules apply only to eligible retirement plans defined under U.S. law. Moving a distribution into a foreign retirement account does not automatically qualify as a U.S. tax-free rollover. Treaty-specific rules should be checked separately.

Will I owe the 10% early-withdrawal tax if I cash out?

A taxable early distribution can be subject to the 10% additional tax, but exceptions exist. One important exception can apply to qualified-plan distributions after separation from service in or after the calendar year you reach age 55. Check the applicable exception before taking or rolling over a distribution.

What happens to a Roth 401(k) if I leave the United States?

The account does not disappear. An eligible designated Roth 401(k) distribution can generally be directly rolled into a Roth IRA. However, Roth 401(k) and Roth IRA five-year rules are not identical, so verify the qualified-distribution consequences before completing a large rollover.

Does moving abroad automatically end my U.S. tax residency?

No. Your residency-ending date is determined under U.S. tax rules, not simply by your flight date or H-1B expiration date. Your departure year can be a dual-status year.
