Leaving the US: a founder's guide to renunciation, exit tax, and where to go
The US taxes citizens on worldwide income no matter where they live - one of only two countries (with Eritrea) that does. For founders with serious income, the only way out is renunciation, and renunciation has an exit tax. This guide walks through the mechanics, then ranks the jurisdictions that actually fit an American who is leaving. Real 2026 data, not advice.

Why leaving the US is different
Almost every country taxes you on where you live (residence-based taxation). If you move out, you stop owing them. The US is different: it taxes on citizenship. A US citizen owes US income tax, files US returns, and reports foreign accounts (FBAR, FATCA) for as long as they hold the passport - no matter how many years they live abroad.
Two provisions reduce the double tax: the Foreign Earned Income Exclusion (FEIE), which excludes a fixed amount of foreign earned income each year ($132,900 for tax year 2026, up from $130,000 in 2025, indexed annually), and the Foreign Tax Credit (FTC), which credits foreign taxes paid against US tax on the same income. Together they can eliminate US tax for mid-income earners in low-tax countries - but not for high earners, and not on capital gains or unearned income. For a founder with a liquidity event, FEIE does not help much.
That is why renunciation is on the table. The catch: the US put an exit tax in place in 2008 (IRC section 877A) to stop wealthy people from simply walking away.
Renounce US citizenship: the process
Renunciation is a legal act, not a paperwork formality. You must appear in person at a US embassy or consulate outside the US, take an oath of renunciation, and pay a processing fee. The State Department cut the fee to $450 effective April 13, 2026 (down from $2,350). You then receive a Certificate of Loss of Nationality. There is no expedited path.
Before you renounce, get your tax history clean. The most expensive of the three covered-expatriate tests to fail is the certification test - if you cannot certify 5 years of US tax compliance, you are a covered expatriate regardless of your net worth. Run the US exit tax calculator for a quick estimate, then confirm with a cross-border CPA.
The US exit tax (covered expatriate rules)
The exit tax applies only to covered expatriates - people who renounce (or give up a long-term green card after 8 of the last 15 years) and meet any one of three tests under IRC section 877A:
- Net worth test. Net worth of at least $2,000,000 on the expatriation date.
- Average tax liability test. A 5-year average annual net US income tax liability above an indexed threshold ($211,000 for tax year 2026, up from $206,000 in 2025; Rev. Proc. 2025-32).
- Certification test. Failure to certify, on Form 8854, 5 years of US tax compliance.
If you are a covered expatriate, you are treated as if you sold every asset you own at fair market value the day before expatriation. You owe tax on unrealized gains above an indexed exclusion ($910,000 for tax year 2026, up from $890,000 in 2025; Rev. Proc. 2025-32). Certain assets - retirement plans, specified tax-deferred accounts - are subject to different rules and can elect deferral (with interest).
Non-covered expatriates owe no mark-to-market exit tax, but still must file Form 8854 to certify compliance and may face separate inheritance-tax rules on later gifts to US persons (IRC section 2801).
Best countries to move to from the US
The best fit for an American is a country that does not tax your foreign income (territorial), has low personal tax, does not run its own worldwide system, has no exit tax of its own, and is reachable via a digital nomad visa or straightforward residency. The ranking below is built from the same dataset as our country scores using an American-fit lens. It excludes jurisdictions on our conflict-region list (currently the UAE).
| # | Country | Fit | Tax system | Top PIT | English | DNV | Why it fits |
|---|---|---|---|---|---|---|---|
| 1 | 🇧🇿 Belize | 100 | Territorial | 0% | very high | Yes | territorial tax (foreign income not taxed locally), a special regime exempts foreign income, 0% top personal rate, no worldwide taxation. |
| 2 | 🇨🇷 Costa Rica | 88 | Territorial | 25% | high | Yes | territorial tax (foreign income not taxed locally), a special regime exempts foreign income, no worldwide taxation, no exit tax. |
| 3 | 🇸🇬 Singapore | 87 | Territorial | 22% | very high | No | territorial tax (foreign income not taxed locally), a special regime exempts foreign income, no worldwide taxation, no exit tax. |

Fit score is a custom 0-100 lens (territorial tax + low personal rate + no worldwide tax + no exit tax + special regime + English + DNV + treaty breadth), not the official jurisdiction score. Treaty count is a proxy for US treaty coverage, not a guarantee - verify any specific US treaty separately.
How the top three compare across all 9 dimensions
The American-fit lens is tailored, but it is worth seeing how the top three score across our full 9-dimension jurisdiction model (tax, funding, visas, residency, ecosystem, family, and more). This is the same radar shown on our comparison pages.
A sensible sequence
- Get 5 years of tax compliance clean. File any missing returns and FBARs. Failing the certification test makes you a covered expatriate regardless of net worth.
- Establish your new residency first. Move to a territorial country, get residency, and run your days through the tax residency calculator.
- Estimate the exit tax. Use the exit tax calculator, then confirm with a cross-border CPA.
- Time the renunciation. If you can drop below a covered-expatriate test legitimately (e.g. reduce net worth via legitimate transactions, or drop average tax liability), the exit tax disappears.
- Renounce and file Form 8854/8855. Book the embassy appointment, take the oath, file the expatriation forms.
This is a framework, not a plan. Every step has traps (step-transaction doctrine, the expatriation waiting period, deferred-asset elections). Get a tax lawyer for your situation.
Frequently asked questions
Can a US citizen stop paying US tax by moving abroad?
No. The US taxes citizens on worldwide income regardless of where they live. Moving abroad lets you claim the Foreign Earned Income Exclusion ($132,900 for tax year 2026, up from $130,000 in 2025, inflation-adjusted each year) and the Foreign Tax Credit, which reduce or eliminate US tax on foreign earned income. The only way to fully exit the US tax system is to renounce US citizenship and (if you are a covered expatriate) pay the exit tax.
What is the US exit tax?
The exit tax (IRC section 877A) applies to covered expatriates - those who renounce or give up a long-term green card and meet one of three tests: net worth at least $2 million, a 5-year average annual net income tax liability above an indexed threshold ($211,000 for tax year 2026), or a failure to certify 5 years of US tax compliance. Covered expatriates are treated as if they sold all assets at fair market value the day before expatriation, and owe tax on unrealized gains above an indexed exclusion ($910,000 for tax year 2026).
Do I have to pay the exit tax if I am not a covered expatriate?
No. If you do not meet any of the three covered-expatriate tests, there is no mark-to-market exit tax on expatriation. You still must certify 5 years of tax compliance on Form 8854, and you remain subject to inheritance-tax rules on gifts or bequests to US persons after expatriation in some cases. Confirm your status with a cross-border tax professional.
Which countries are the best fit for Americans leaving the US?
Countries with a territorial tax system (foreign income not taxed locally), low personal income tax, no worldwide taxation, no exit tax, and a digital nomad visa or straightforward residency. Panama, Costa Rica, Portugal, Paraguay, and Ireland score well on this American-fit lens. See the ranked table below - it is built from the same dataset as our country scores, not legal advice.
How long does it take to renounce US citizenship?
The administrative part - booking a renunciation appointment at a US embassy or consulate, taking the oath, and receiving a Certificate of Loss of Nationality - usually takes a few months. The tax part can take longer: you must file Form 8855 (initial expatriation statement) and certify 5 years of tax compliance on Form 8854. Plan for 6 to 12 months end to end, depending on embassy wait times and your tax history.
Will I still owe US tax after I renounce?
Generally no - after renunciation you are a nonresident alien taxed only on US-source income. Two catches: (1) if you are a covered expatriate, the exit tax applies at expatriation; and (2) gifts or bequests you make to US persons after expatriation can be taxed at the highest gift/estate rate under IRC section 2801. Your future US-source income (rental, dividends from US companies) may also be subject to withholding.
