Exit Tax
Exit Tax meaning
A tax levied on individuals who permanently leave a country's tax system by renouncing citizenship or long-term residency. For the US, it's calculated as a deemed sale of all your worldwide assets at fair market value on the day before you expatriate. It's steep, often unavoidable, and frequently the largest single tax bill high-net-worth people ever encounter.
The US exit tax (Section 877A)
The US Congress enacted this in 2008 to prevent wealthy Americans from simply renouncing citizenship and walking away from US tax liability. It applies to "covered expatriates" — a specifically defined category that most high-net-worth individuals fall into.
You're a covered expatriate if you meet any of three tests. First: your average annual net income tax liability over the five tax years before expatriation exceeded a threshold amount (roughly $201,000 for 2024, adjusted annually). Second: your net worth on the date of expatriation exceeded $2 million. Third: you can't certify that you've been compliant with US tax filing requirements for the five preceding years.
The second test is the binding constraint for most CBI clients. Anyone worth $2 million or more is a covered expatriate. And given that most CBI programs require significant investment minimums, most CBI clients easily exceed $2 million net worth. This isn't an escape hatch available to wealthy people — it's a near-certain tax bill.
If you're a covered expatriate, on the day immediately before you renounce or surrender your green card, every asset you own worldwide is deemed sold at fair market value. This is a constructive sale. You didn't actually sell anything, but the IRS treats the transaction as complete. You owe capital gains tax on the unrealized appreciation of every asset.
How the exit tax is calculated
The math is brutal because it doesn't distinguish between liquid and illiquid assets. You own investment real estate worth $5 million that you bought for $2 million. That $3 million in unrealized gains is subject to capital gains tax. You own a private business worth $10 million with $6 million in unrealized gains. Same treatment. You own a concentrated stock position in company shares worth $4 million with $3.2 million in unrealized gains. Same treatment.
There's an exclusion amount — roughly $886,000 for 2024. Gains above that amount are taxed. So if your total unrealized gains across all assets exceed $886,000, the excess is taxable. For a high-net-worth person with diversified holdings, this exclusion is meaningful but not transformative. Someone with $5 million in unrealized gains pays tax on $4.1 million.
The tax rate is the long-term capital gains rate, currently 20% federal plus the 3.8% net investment income surtax plus any state income tax. For a high-income California resident, this can total 40%+. On $4 million in excess gains, that's $1.6 million in exit tax before any other considerations.
Special rules for deferred compensation and retirement accounts
Retirement accounts and deferred compensation get punitive treatment. If you've accumulated $3 million in a traditional IRA or 401(k), that balance is subject to exit tax treatment on expatriation. You don't escape by leaving it in the account.
Worse, when you eventually take distributions from that account — whether five years later or twenty years later — the US applies a 30% withholding rate to the distribution, regardless of what tax treaty provisions might otherwise allow. This isn't a one-time tax; it's a permanent withholding applied to every future distribution.
For someone with substantial retirement savings, this creates a dilemma. You can take the exit tax hit on expatriation (recognizing the full balance as income), or you can defer it and accept the 30% withholding on every future distribution. Neither option is clean. Many people choose to accelerate the income recognition during the year of expatriation to get some tax planning benefit, but the fundamental problem remains: retirement accounts don't shield you from exit tax.
Why this matters for CBI clients planning US renunciation
If you're a US citizen acquiring a second passport with the ultimate goal of renouncing US citizenship, the exit tax is not hypothetical. It's a concrete dollar cost you must budget.
Scenario: a US citizen with $5 million in net worth, considering renouncing to acquire Dominican citizenship. Assume $2 million in unrealized gains (reasonable for someone with investments and real estate). After the exclusion, that's $1.1 million in taxable gains. At 20% capital gains tax, that's $220,000 in federal tax, plus state taxes if applicable, plus the 3.8% surtax. For a California resident, total exit tax could exceed $400,000.
This isn't a theoretical exercise. The US actually collects this tax. The IRS requires covered expatriates to file Form 8854 with their renunciation documentation. Many countries now require exit tax certification before approving renunciation. The practical effect is that you cannot renounce without dealing with this.
Other countries with exit taxes
The US isn't unique. Canada treats emigrants as having sold all their assets, though the exclusion is higher and the mechanics are slightly different. Australian residents pay capital gains tax on ceasing residency. Germany has an exit tax on shares exceeding 1% of a corporation. France levies an exit tax on unrealized gains above €800,000. Netherlands, Norway, South Africa, and several others have versions of this concept.
The idea is spreading. Countries have caught onto the fact that not collecting exit taxes leaves money on the table when wealthy residents depart. Expect more countries to implement versions of this as CBI becomes more common.
Countries without exit taxes
Most Caribbean CBI nations don't have exit taxes. Grenada, St. Kitts, Dominica, Antigua, Citizenship by Investment programs in these islands don't impose exit tax when you leave. This is actually a point in their favor relative to higher-tax jurisdictions.
The UK has no formal exit tax per se, but rules around "temporary non-residence" can drag you back into the UK tax system if you depart and return within certain windows. UAE has no exit tax. Singapore has no exit tax. These are factors in choosing where to establish residency if you're planning to eventually depart a high-tax country.
The 5-year shadow period and ongoing complications
Renouncing US citizenship or surrendering your green card doesn't erase your connection to US tax law. For ten years after expatriation, you remain subject to US estate and gift tax on US-situs (located) assets. This includes US real estate, US business interests, and securities in US companies.
Additionally, if you gift or bequeath assets to US persons after expatriation, there's a special tax on the recipient. These "covered gifts and bequests" are taxable to the US person recipient if they exceed certain thresholds. This is a tax on the recipient, not on you, but it's a complication that follows your expatriation.
The practical consequence: someone renouncing US citizenship to acquire Irish citizenship can't entirely escape US tax exposure for a full decade. Properties in the US remain subject to US estate taxes. Gifts to US children get complicated.
Planning strategies to reduce exit tax
Timing matters. Exit taxes are based on asset values on the date of expatriation. If you can control that date, you can influence the tax. Renouncing during a market downturn when asset values are depressed results in lower exit taxes than renouncing during a bull market. This isn't theoretical — it's a real planning variable.
Gifting appreciated assets before expatriation can work. If you gift appreciated real estate to a spouse or children before renouncing, those assets are no longer yours on the date of expatriation and aren't subject to exit tax. But this requires planning and execution well in advance. And gifts can trigger their own tax consequences.
Accelerating ordinary income recognition into years before renunciation can be strategic. If you have the option to recognize business income or take bonuses in the year before renunciation, you might do so at lower effective rates than the alternative. This sounds counterintuitive, but the math sometimes works in your favor if the exit tax on other assets is unavoidable.
Using the exclusion amount strategically by structuring gains can matter for some people. If you have flexibility in which assets you liquidate before expatriation, liquidating those with smaller gains first preserves the exclusion amount for larger gains later.
For most people, however, the exit tax is baked in. There's no getting around it. The conversation is about magnitude and timing, not elimination.
The bottom line on exit tax and CBI
If you're a US citizen considering renunciation as part of CBI planning, the exit tax is not a friction cost you can ignore. For someone with $5 million in assets and $2 million in unrealized gains, exit tax could easily exceed $400,000 to $600,000 in total federal and state taxes. This needs to be budgeted, planned for, and understood before you commit to renunciation.
Some CBI clients factor this into the cost-benefit analysis and decide it's worth it. The relief from FATCA reporting, the elimination of worldwide tax reporting, the ability to move assets internationally without US tax impediments — for some people, this justifies paying the exit tax. For others, it's the barrier that makes renunciation impractical.
Either way, the exit tax is non-negotiable. It's law, it's collected, and it's substantial.
