401(k), IRA & Roth: Your U.S. Retirement Guide for 2026

Why retirement planning matters even if you just arrived

Many new arrivals put off thinking about retirement, assuming they'll move back home eventually, or because the priority right now is getting settled. But U.S. retirement accounts carry an immediate tax advantage (lowering your taxable income) plus, in the case of a 401(k), free money from an employer match — an opportunity you lose every month you delay, whether you end up staying in the U.S. permanently or leaving after a few years.

401(k): the employer-sponsored plan

A 401(k) is a retirement account your employer offers, with contributions deducted directly from your paycheck before tax (Traditional) or after tax (Roth 401(k), if your employer offers it). Its biggest advantage is usually the "employer match": your employer adds money equal to part or all of your contribution, up to a set percentage of your salary. That's literally free money, which is why most financial advisors recommend contributing at least enough to get the full employer match before considering any other investment.

2026 401(k) contribution limits

These figures are the employee's own contribution limit only. The combined limit across your contribution and the employer match together reaches $72,000 for 2026 ($80,000 with catch-up, up to $83,250 for ages 60–63), per the IRS.

IRA: your own account, independent of your job

An IRA (Individual Retirement Account) is one you open yourself at any bank or brokerage, regardless of your employment status, as long as you have taxable income. For 2026, the maximum contribution is $7,500 for those under 50, rising to $8,600 for those 50 and older — and this limit is combined across Traditional and Roth accounts together, not per account type.

Traditional vs. Roth: which should you choose?

The core difference is when you pay tax:

• Traditional: your contribution reduces your taxable income now (an immediate tax break), but you pay full income tax on withdrawals in retirement.
• Roth: you pay tax on your contribution now (no upfront deduction), but qualified withdrawals in retirement are entirely tax-free, including accumulated investment gains.

A rough rule of thumb: if you expect your tax bracket in retirement to be lower than it is now, Traditional is usually a better fit. If you're early in your career and expect higher income later, Roth may work better. This is a personal decision that depends on your finances, so consult a licensed financial advisor before deciding.

What happens to your account if you leave the U.S. permanently

This worries many Arab immigrants who plan to eventually return home after years of working in the U.S. You generally have three options:

1. Leave it in place: you can usually keep a 401(k) or IRA with the plan provider even after leaving the U.S., and your money keeps growing until you decide to withdraw at retirement age.
2. Roll it over: a 401(k) balance can be moved into an IRA without immediate tax if done as a direct transfer between providers.
3. Cash it out entirely: possible, but usually the worst option tax-wise, especially before age 59½.

A full early cash-out (before 59½) is generally subject to full federal income tax plus a 10% early-withdrawal penalty. And if you later become a tax nonresident alien after permanently leaving the U.S., future retirement payments may face a flat 30% withholding unless an existing tax treaty between the U.S. and your country reduces it. Check whether such a treaty exists between the U.S. and Egypt, Jordan, or any other Arab country before deciding, and consult a tax accountant experienced in international taxation.

Islamic finance considerations: is a 401(k) halal?

This is a purely religious question we don't issue rulings on; scholars and Islamic finance advisors differ depending on the type and nature of the investments inside the account. What we can say practically: most 401(k) plans let you choose how your contribution is invested among several options, usually including stock funds alongside interest-based bond funds. Many people choose to direct their contribution only toward stock funds and avoid bond funds for this reason, but that doesn't automatically mean the stock fund itself is fully Sharia-compliant, since that depends on the underlying companies. Some self-directed IRAs also offer Sharia-screened fund options. Consult a trusted religious scholar or a specialized Islamic finance advisor before deciding — none of the above is a religious ruling or investment advice.

What about Social Security?

A 401(k) and IRA are entirely separate from Social Security, a mandatory government program automatically deducted from your paycheck regardless of whether you also contribute to a private retirement plan. You generally need to accumulate 40 work "credits" (roughly equivalent to 10 years of documented work) to qualify for a Social Security retirement benefit. If you leave the U.S. before reaching that threshold, you may not qualify for a benefit later. The U.S. has Social Security "Totalization Agreements" with a number of countries that combine work years between the two countries for this purpose, but you should verify directly on the official SSA site whether your home country is on that list before building any decision around it. See our Social Security number guide for more detail.

Can I contribute to an IRA on a temporary work visa?

Yes. The law doesn't require citizenship or a green card to contribute to an IRA — only that you have taxable earned income in the U.S. (W-2 or 1099) and a tax identification number (a Social Security number or, in certain cases, an ITIN). Even on an H-1B or F-1 visa with work authorization, you can open an IRA under the same rules that apply to anyone else working in the U.S., as long as you file an annual tax return.

Common mistakes

• Not contributing enough to get the full employer match, which means leaving free money on the table.
• Cashing out the full balance when changing jobs instead of rolling it over, exposing yourself to unnecessary tax and penalties.
• Ignoring the Roth IRA income limit and contributing anyway despite exceeding it, which can require a correction with the IRS later.
• Not learning the nonresident alien withholding rules before permanently leaving the U.S.

What to do next

If you're still getting your basic tax paperwork in order, start with our U.S. taxes guide for immigrants to understand the full picture. If you're planning to send part of your savings to family abroad instead of investing now, check our guide to sending money from the U.S. to compare options. And for any major retirement or tax decision, consult a licensed CPA who understands your situation as an immigrant specifically, since some rules depend on the tax treaty between the U.S. and your home country.
