“I am 25 and working in the US on an H-1B visa. My employer offers a 50% 401(k) match up to $12,250 a year. I am currently maxing it out, but I might leave the US and withdraw the money in 5 to 10 years. Given the early withdrawal penalties and taxes, does it still make sense to max out my 401(k), or should I only contribute enough to get the full match and invest the rest elsewhere?”
You don’t have to destroy the tax shelter just because you may leave the U.S.; leaving it or using a direct rollover usually avoids immediate tax and penalties. A fully vested 50% match also goes a long way—even after penalties, employer dollars typically leave you ahead versus no match.
You have two contribution branches now and three practical ways to handle the account when you leave.
Keep maxing it: a 50% match reaches $12,250 only after a $24,500 employee , which is the 2026 limit [1]. You contribute $24,500 and the employer adds $12,250, so “max out” and “get the full match” are the same choice.
Contribute at least $12,250 to receive the full $6,125 match. For the unmatched $12,250 before the $24,500 limit [1], keep using the 401(k) only if you’ll preserve it through a rollover; if you’ll likely spend it in ~5–10 years, a liquid avoids the 10% retirement‑plan penalty on early 401(k) withdrawals [3][11].
Leaving the United States does not require liquidation. After termination, you can leave funds, roll to a new plan, or roll to an IRA; a trustee‑to‑trustee avoids current tax and the 20% mandatory withholding that applies to cash paid to you [4][5].
If part of the balance is in a , roll that part directly to a Roth IRA. Regulations treat the rolled Roth‑401(k) basis as a regular Roth IRA contribution, and Roth IRA ordering rules pay out regular contributions first—so you can access rolled without U.S. income tax or the 10% tax, keeping earnings invested [7].
Legally available after severance but typically the most expensive route: 10% additional tax on the taxable portion under IRC 72(t), plus regular income tax [3]. For nonqualified Roth-plan payouts, only the earnings portion is taxable/penalized [6].
avoid the 10% additional tax only if you don’t modify them until the later of five years or age 59½—starting at 25 would lock you in for decades [12].
All match calculations assume the employer contribution is fully ; use only the vested amount if it is not.
These steps capture the full match now while preserving access and minimizing avoidable tax when you leave.
Before changing payroll
Decode the exact match and vesting terms
Find the sentence with “50%” and “$12,250” in the SPD. If $12,250 is the maximum employer match, the employee amount needed is $12,250 ÷ 50% = $24,500; if it is the maximum employee contribution matched, the required contribution is $12,250 and the employer amount is $6,125. Confirm whether matching is calculated per paycheck or annually and whether there is a year‑end true‑up; the plan document controls both [9].
Requirements
For the remaining 2026 paychecks
Set the 2026 payroll contribution
If $12,250 is the employer’s cap, target total 2026 s of $24,500 (the IRS limit) [1]. If $12,250 is the match‑eligible portion of your own contribution, target at least that amount, and add unmatched contributions only if you plan to keep the money invested long‑term or roll it over later.
Requirements
Only for unmatched money
Put near‑term unmatched money in a taxable account
If you realistically expect to spend unmatched money at age 30–35, use a rather than planning an early 401(k) withdrawal subject to a 10% additional tax [3]. In a taxable account, gains are measured against and holdings over one year are generally long‑term [11].
Requirements
After severance, before taking cash
Request a direct rollover when employment ends
Ask the 401(k) administrator to pay the receiving trustee directly. A has no current U.S. tax and avoids the 20% mandatory withholding that applies when a taxable distribution is paid to you [5].
Requirements
Before requesting an overseas cash payment
Use Form W‑8BEN before any payment abroad
Provide Form W‑8BEN to the plan so it can apply the correct treaty rate instead of the 30% default; the form generally stays valid through December 31 of the third succeeding calendar year and must be renewed within 30 days after changes [8][13].
Requirements
The year after a foreign payment
Reconcile a foreign cash‑out on Form 1040‑NR
File Form 1040‑NR and attach Form 1042‑S to reconcile withholding with the actual U.S. tax under the treaty. If you request a refund of tax withheld on a Form 1042‑S, the IRS notes it may take up to 6 months to process [15].
Requirements
You are not the first to go through this. Here is how it went for others who asked the same thing.
u/sadbrownmanr/h1bMar 3, 2026
The answer rests on the Internal Revenue Code, Treasury regulations, IRS 2026 retirement and international-tax guidance, IRS form instructions, and Department of Labor/ERISA plan-document rules.
IRS 2026 401(k) limits
The 2026 employee 401(k) contribution limit is $24,500.
Highlights of changes for 2026
The annual contribution limit for employees who participate in 401(k), 403(b), governmental 457 plans, and the federal government’s Thrift Savings Plan is increased to $24,500, up from $23,500 for 2025.
IRS 401(k) plan overview
Traditional deferrals get current tax deferral; Roth deferrals are currently taxable.
401(k) plan overview; Tax advantages
Generally, deferred wages (elective deferrals) are not subject to federal income tax withholding at the time of deferral, and they are not reported as taxable income on the employee’s individual income tax return. Roth deferrals are included in the employee's taxable income in the year of the deferral. Elective deferrals and investment gains are not currently taxed and enjoy tax deferral until distribution.
IRC 72(t)(1)
Early qualified-plan distributions generally incur a 10% additional tax on the taxable portion unless an exception applies.
(t)(1)
If any taxpayer receives any amount from a qualified retirement plan (as defined in section 4974(c)), the taxpayer's tax under this chapter for the taxable year in which such amount is received shall be increased by an amount equal to 10 percent of the portion of such amount which is includible in gross income.
IRS Retirement Topics—Termination of Employment
After termination, you can leave the money, roll to a new plan, withdraw, or roll to an IRA.
Options for your account balance
Generally, when you terminate employment, you have four options for your account balance: 1. Leave your money in the plan. 2. Rollover to a new employer's plan. 3. Withdraw the balance. 4. Rollover to an IRA.
IRS Rollover Rules
Direct rollovers have no current withholding; cash paid to you generally has 20% withholding.
How do I complete a rollover?
Direct rollover – If you're getting a distribution from a retirement plan, you can ask your plan administrator to make the payment directly to another retirement plan or to an IRA. No taxes will be withheld from your transfer amount. A retirement plan distribution paid to you is subject to mandatory withholding of 20%, even if you intend to roll it over later.
IRS Designated Roth Account Rules
Nonqualified Roth 401(k) payouts are split between basis and earnings; only the earnings portion is taxable/penalized.
Nonqualified distributions
A distribution that is not a qualified distribution will be partially included in gross income if there are earnings in the account. The distribution will be treated as coming pro-rata from earnings and contributions (basis). The 10% tax on early withdrawals may apply to the part of the distribution that is includible in gross income.
26 CFR 1.408A-10
Roth-401(k) basis rolled to a Roth IRA is treated as regular contributions; Roth IRA pays out regular contributions before earnings.
A-3
For purposes of section 408A(d)(4), the amount of a rollover contribution that is treated as a regular contribution is the portion of the distribution that is treated as investment in the contract under A-6 of § 1.402A-1, and the remainder of the rollover contribution is treated as earnings. Under section 408A(d)(4), distributions from Roth IRAs are deemed to consist first of regular contributions, then of conversion contributions, and finally, of earnings.
IRC 1441 / IRS Foreign Plan Distributions
Default 30% withholding to foreign payees unless valid documentation/treaty applies; lump sums may not be covered by treaty exemptions.
Payments to foreign persons; Pensions, annuities, and alimony
You must generally withhold 30% from a plan distribution paid to a foreign payee unless you can reliably associate the payment with valid documentation. Most tax treaties provide an exemption from tax on non-government pensions and annuities. The foreign person entitled to the payments must provide you with a Form W-8BEN that contains the TIN of the foreign person. The exemption may not apply to lump-sum payments.
IRS 401(k) Match Fix-It Guide
The plan document controls the match formula and timing—not summaries.
How to find the mistake
Review the plan document to determine the employee eligibility requirements and matching contribution formula and compare it to what's used in operation. Review the timing of the matching contribution in comparison to the plan document requirements.
IRC 411(a)(2)(B) / IRS Vesting Snapshot
Federal rules allow 3‑year cliff or 6‑year graded vesting for matching contributions.
Vesting requirements
There are two alternative minimum vesting schedules. Under the first option, contributions must be 100% vested when a participant completes 3 years of service (commonly referred to as 3-year cliff vesting). Under the second option, contributions vest gradually over 6 years, and a participant must be 100% vested upon completing 6 years of service.
IRS Topic 409
In a taxable account, gains are measured over basis; holding over a year is generally long‑term.
Capital gain or loss; Short-term or long-term
When you sell a capital asset, the difference between the adjusted basis in the asset and the amount you realized from the sale is a capital gain or a capital loss. Generally, if you hold the asset for more than one year before you dispose of it, your capital gain or loss is long-term.
IRC 72(t)(2)(A)(iv) / IRS SoSEPP Guidance
SoSEPP schedules cannot be modified until the later of 5 years or age 59½.
Q&A 2
The taxpayer does not modify the SoSEPP (other than by reason of death, disability, or distribution to a qualified public safety officer under Section 72(t)(10)) before the date that is the later of: The 5th anniversary of the date of the first SoSEPP payment; and The date the taxpayer reaches age 59 ½.
Instructions for Form W-8BEN
Form W‑8BEN typically remains valid through the end of the third succeeding calendar year; new form due within 30 days after changes.
Expiration of Form W-8BEN; Change in circumstances
Generally, a Form W-8BEN will remain in effect for purposes of establishing foreign status for a period starting on the date the form is signed and ending on the last day of the third succeeding calendar year, unless a change in circumstances makes any information on the form incorrect. If a change in circumstances makes any information on the Form W-8BEN you have submitted incorrect, you must notify the withholding agent, payer, or FFI with which you hold an account within 30 days of the change in circumstances and you must file a new Form W-8BEN or other appropriate form.
IRC 402(g) – Excess Deferrals
The employee deferral cap is an individual, across‑plans limit—you must aggregate deferrals to all plans.
The 402(g) limit is an individual limit and not a plan limit, so you must aggregate all elective deferrals contributed to all the plans in which you participate
Instructions for Form 1040-NR (2025)
Processing time for refunds claimed with Form 1042‑S on Form 1040‑NR can be up to 6 months.
