Your IRA and 401(k) After Renunciation: What You Keep, What You Lose

The Accounts Don’t Disappear — But the Rules Change

Here’s the question I hear from almost every expat with a six-figure retirement account: “Do I lose my IRA when I renounce?” The short answer is no. Your retirement accounts don’t evaporate when you hand in your passport. The money is yours. It stays in the account. It keeps growing (or shrinking, depending on the market and your investment choices).

What changes is everything around the account: how distributions are taxed, which treaty benefits apply, whether your brokerage will keep you as a client, and whether you’ve accidentally triggered a punitive withholding regime that no treaty can fix. The accounts survive. The tax treatment gets complicated.

The 30% Withholding: The Default That Nobody Likes

Once you renounce, you’re a non-resident alien (NRA) in the eyes of the IRS. Distributions from traditional IRAs and 401(k)s paid to NRAs are subject to a 30% federal withholding tax under IRC Section 871. This is withheld at source — your custodian takes it out before the money hits your account.

That $50,000 annual distribution you planned your retirement around? You get $35,000. The other $15,000 goes straight to the IRS before you see a dime.

This is the default. It applies to the entire taxable portion of the distribution, not just the gains. For a traditional IRA where all contributions were pre-tax, that means 30% of every dollar coming out.

The withholding is not a separate tax — it’s prepayment of the tax you owe as an NRA on US-source income. But unlike when you were a citizen filing a 1040 with graduated brackets, deductions, and credits, the 30% rate is flat. No standard deduction. No itemizing. Thirty percent, full stop.

Tax Treaties: Where You Live Determines What You Pay

The 30% default rate is just that — a default. The US has income tax treaties with dozens of countries, and many include articles that reduce withholding on pension and retirement distributions.

Canada: The US-Canada treaty generally limits withholding on periodic pension payments (including IRA distributions) to 15%. Lump-sum distributions may still face the full 30%. Canada then taxes the income under its own rules and gives you a foreign tax credit for the US withholding. Net result: you pay tax, but roughly at your marginal Canadian rate rather than being double-taxed.

United Kingdom: The US-UK treaty can reduce withholding on pension distributions to 0% in many cases — the income is taxable only in the country of residence. This is one of the most favorable treaty outcomes for former citizens with US retirement accounts.

Germany: Similar to the UK in many respects. Periodic distributions are generally taxable only in Germany under the treaty, meaning zero US withholding. Germany taxes the income at German rates.

Australia: No help. The US-Australia treaty does not reduce withholding on IRA or 401(k) distributions for NRAs. You’re stuck with 30%. Given how many Americans end up in Australia, this one stings.

To claim treaty benefits, you need to file Form W-8BEN with your custodian. Some custodians are better at processing these than others. Some will apply the reduced rate prospectively; others will withhold 30% and leave you to file Form 1040-NR to claim a refund. Either way, you’re filing US tax paperwork. Welcome to your post-renunciation life — still dealing with the IRS, just from farther away.

The Exit Tax Exception: IRAs Get Their Own (Worse) Rules

Here’s where people get confused. The exit tax uses a mark-to-market deemed sale framework — you’re treated as if you sold all your assets the day before expatriation. But traditional IRAs and 401(k)s are specifically excluded from the deemed sale. Sounds like good news, right?

It’s not. Instead of the deemed sale, covered expatriates get hit with a separate regime under IRC Section 877A(d)(3). All future distributions from “specified tax deferred accounts” — your IRA, 401(k), 403(b), the works — are subject to 30% withholding with no treaty benefits available. Read that again. No treaty benefits. It doesn’t matter if you live in the UK, Germany, or anywhere else with a generous treaty. Covered expatriates pay 30% on every distribution, period.

This is the penalty for being a covered expatriate with retirement accounts. The government didn’t tax your IRA on the way out via deemed sale, so instead they lock in the worst possible withholding rate on the way out via distributions. For someone with a $1.5 million traditional IRA, the difference between 0% treaty withholding (UK resident, non-covered) and 30% mandatory withholding (covered expatriate, any country) is enormous over a 25-year retirement.

The math: $60,000 annual distribution over 25 years. Non-covered expatriate in the UK pays $0 in US withholding. Covered expatriate pays $18,000 per year — $450,000 total. Same account, same person, different covered expatriate status. That’s the stakes.

Roth IRA: The Exception to the Exception

Roth IRAs are the one genuinely bright spot in this picture, and understanding why requires a quick detour into how they’re structured.

You contributed to a Roth with after-tax dollars. The growth is tax-free. Qualified distributions — those meeting the 5-year rule and age 59-1/2 requirement — are tax-free to US citizens, and they remain tax-free to NRAs. The IRS already got its cut on the front end.

After renunciation, qualified Roth distributions are not subject to withholding. The account continues to grow tax-free. You can leave it alone for years, and the compounding works entirely in your favor with no US tax drag.

The catch for covered expatriates: non-qualified Roth distributions (before age 59-1/2 or before the 5-year period) can be subject to the same 30% no-treaty-benefit withholding that applies to traditional accounts. And there’s a subtlety around how basis recovery works for NRAs that can create unexpected tax liability on what you thought was a tax-free withdrawal.

Strategy implication: If you’re planning to renounce and you have both traditional and Roth accounts, the Roth is almost always the one to preserve. Convert traditional to Roth before renouncing if the current-year tax hit is manageable. You’ll pay ordinary income tax as a US citizen (at graduated rates, with deductions), and then the Roth grows and distributes tax-free forever after.

Should You Withdraw Before or After? The Numbers

This is the question everyone wants answered, and the honest answer is: it depends. But let me run some scenarios.

Scenario 1: Non-covered expatriate, moving to the UK. You have $400,000 in a traditional IRA. The US-UK treaty eliminates withholding on periodic distributions. If you withdraw after renouncing, you pay $0 in US tax (the UK taxes it at UK rates). If you withdraw before renouncing, you pay US ordinary income tax — say 22-24% federal plus state taxes. Clear winner: withdraw after.

Scenario 2: Covered expatriate, moving to Germany. Same $400,000 traditional IRA. As a covered expatriate, you pay 30% on all distributions regardless of treaty. If you withdraw before renouncing, you pay ordinary income tax as a US citizen — maybe 24% federal, depending on other income. Plus you avoid the 10% early withdrawal penalty if you’re over 59-1/2. In this case, withdrawing before renunciation might save you 6% on every dollar. On $400,000, that’s $24,000.

Scenario 3: Non-covered expatriate, moving to Australia. No treaty relief on retirement distributions. You’re paying 30% either way as an NRA. But as a citizen, you’d pay at graduated rates — likely lower than 30% for most middle-income retirees. Withdraw before, at least partially.

The common thread: if you’re going to be a covered expatriate, seriously consider accelerating distributions before your expatriation date. Pay the tax as a citizen at graduated rates rather than as a covered expatriate at a flat, treaty-proof 30%.

Custodian Complications: The Brokerage Problem

Here’s a practical issue that the tax code doesn’t warn you about: many US brokerages don’t want NRA clients. Vanguard, Fidelity, and Schwab all have varying policies on maintaining accounts for non-resident aliens. Some will keep your existing accounts but won’t let you open new ones. Some will restrict trading. Some will give you a timeline to transfer out.

After you renounce, you need to update your W-8BEN status with every financial institution where you hold accounts. When you do, some of them will start asking uncomfortable questions. A few will flat-out close your account and send you a check — triggering a taxable distribution you didn’t plan for, complete with withholding.

Before you expatriate, call your custodian. Ask specifically: “If I become a non-resident alien, will you maintain my IRA?” Get the answer in writing if you can. If they won’t, identify a custodian that will and initiate a trustee-to-trustee transfer before you renounce. Interactive Brokers is generally more NRA-friendly than the big three domestic brokerages.

RMDs: They Don’t Stop at the Border

Required minimum distributions still apply to NRAs. Once you hit RMD age (currently 73, rising to 75 in 2033), you’re required to take distributions from traditional IRAs and 401(k)s regardless of your citizenship status. The RMD rules are based on IRS life expectancy tables and your account balance — not your passport.

If you fail to take RMDs, the penalty is a 25% excise tax on the amount you should have withdrawn (reduced to 10% if corrected within two years). This penalty applies to NRAs the same as it applies to citizens. And your custodian is required to withhold 30% (or the applicable treaty rate) on each RMD.

The planning angle: if you’re approaching RMD age and plan to renounce, consider whether it makes sense to do Roth conversions now — while you’re still a citizen paying graduated rates — to reduce future RMDs that will be subject to flat 30% withholding.

Rollovers: What You Can’t Do Anymore

Once you’re an NRA, your ability to do rollovers and conversions is severely limited. You can’t make new contributions to an IRA (no US earned income). Roth conversions become complicated — most custodians won’t process them for NRAs, and the tax treatment is murky at best.

Trustee-to-trustee transfers between IRAs at different custodians still work — you’re moving the account, not making a contribution. But the 60-day rollover (where you receive a distribution and redeposit it) becomes a minefield. The distribution triggers withholding, and getting it redeposited within 60 days while dealing with international wire transfers and NRA paperwork is harder than it sounds.

Do your rollovers, consolidations, and Roth conversions before you renounce. Once you’re on the other side, the doors that were open quietly close.

The Practical Takeaway

Your IRA and 401(k) survive renunciation. The money is still yours. But the tax wrapper around those accounts changes in ways that matter enormously over a multi-decade retirement.

If you’re not a covered expatriate, treaty planning is your primary tool. Move to a country with a favorable treaty, file your W-8BEN, and your effective withholding rate on distributions could be anywhere from 0% to 15% instead of 30%.

If you are — or will be — a covered expatriate, the calculus shifts hard toward pre-renunciation planning. Accelerate distributions, convert to Roth, and pay tax as a citizen at graduated rates rather than as a covered expatriate at 30% with no treaty escape hatch.

And whatever you do, make sure your brokerage will still talk to you after you change your W-8 status. Losing your custodian is a solvable problem, but only if you solve it before you’re standing outside the US consulate with your Certificate of Loss of Nationality wondering why Vanguard just froze your account.
