Renouncing a passport is one of the few tax decisions you cannot undo. Which is exactly why so many nomads think about it too casually, and why the ones who do it properly plan for years, not months.

Key Numbers to Know (2026)

• US renunciation State Department fee: USD $2,350

• US "covered expatriate" thresholds: net worth over $2,000,000, OR average annual net income tax liability over $211,000 for the five years before expatriating (2026 figure, up from $206,000 in 2025), OR non-compliance with five years of US tax filing

• US exit tax: mark-to-market gain on worldwide assets for covered expatriates, above a $910,000 exclusion for 2026 (up from $890,000 in 2025)

• UK "domicile of origin" complexity: can persist even after UK citizenship is renounced

• Australian renunciation cost: modest administrative fee

• Canadian renunciation: relatively straightforward; modest processing fee

• Requirement: you must already hold another citizenship; renouncing into statelessness generally isn't permitted

When Renunciation Makes Sense

It makes the most sense for US citizens who've built a genuinely permanent life elsewhere with no plan to return. Citizenship-based taxation means the IRS follows you regardless of where you live, and renunciation is the only way to actually stop that. It can also make sense for UK citizens navigating a more complicated position since the 2025 non-dom repeal, though renunciation itself remains uncommon among Britons. Dual citizens whose second passport is a pure administrative burden should consider it too, as should anyone whose original citizenship creates a specific, ongoing problem, such as sanctions exposure, banking friction, or visa restrictions, that follows them regardless of where they've settled.

When Renunciation Doesn't Make Sense

It doesn't make sense if there's a real chance you'll want to return. Renunciation is essentially permanent, and while narrow reinstatement paths exist for a few nationalities, the US isn't one of them. It doesn't make sense if you have strong family ties at home: inheritance, ageing parents, a family business, or simply the ability to visit without a visa can outweigh the tax savings on their own. Run the actual math before deciding, too, since the tax cost of renouncing, including any exit tax, can exceed the ongoing cost of keeping the citizenship you're trying to shed. And it never makes sense without a secure alternative citizenship already in hand, since no country will let you renounce into statelessness, or when you're genuinely uncertain. This isn't a decision to make on a bad tax year.

The US Renunciation Process

This is the most complex and consequential path by some distance. Prerequisites include holding another citizenship, full compliance with five years of US tax filing, and a real understanding of the covered-expatriate exit tax before you start. The process itself runs through an appointment at a US embassy or consulate abroad, a formal renunciation oath, payment of the $2,350 fee, a waiting period of weeks to months for the Certificate of Loss of Nationality, and final US tax filings including Form 8854.

The exit tax applies only to covered expatriates. It treats you as though you sold every asset the day before expatriation, taxing the mark-to-market gain above a $910,000 exclusion for 2026, with separate rules for retirement accounts, deferred compensation, and non-grantor trusts. For a covered expatriate with substantial assets, that bill can be enormous, and it comes due whether or not you've actually sold anything.

Renunciation Outside the US

UK, Australian, and Canadian renunciation are all comparatively simple by contrast: an application to the Home Office, the Department of Home Affairs, or IRCC respectively, a modest fee, and processing measured in weeks rather than months. The complexity in each case sits outside the renunciation itself. UK domicile is a common-law concept separate from citizenship, and giving up a UK passport doesn't automatically clear UK tax connections built on decades of domicile; specialist advice is still needed. Australian and Canadian tax residency are both separately established and separately broken, so surrendering the passport doesn't, on its own, end either country's tax claim on you.

What Renunciation Actually Feels Like

Renunciation is a significant personal decision, and most people who've done it report real emotional weight, even when the financial and practical logic was never in doubt. Consulate ceremonies are often described as sombre. Making a decision this permanent carries a psychological cost that a spreadsheet doesn't capture, and it isn't one to make on tax grounds alone if that cost feels high to you.

Getting the Sequencing Right

Specialist advice covering both jurisdictions, the one you're leaving and the one you're based in, isn't optional at this point. Model the exit tax in full if you're American, and compare the ongoing cost of keeping the citizenship against the one-time cost of renouncing it. Think carefully about timing relative to any major asset sale, and make sure your alternative citizenship is fully secure before you start the process. None of this should be rushed.

Before You Sign the Papers

Renunciation is permanent, and the exit tax math is unforgiving if you get the sequencing wrong. Send us your net worth, your average income over the last five years, and your target date, and we'll model the exit tax and the timing together before you book anything with a consulate.
