Almost every country taxes you for living there. The United States taxes you for being American — and then taxes you again to leave. The US is one of only two countries in the world with citizenship-based taxation: an American files and pays US tax on worldwide income wherever they live. Moving to Bulgaria does not end that. What ends it is formally renouncing citizenship or abandoning a long-term green card — and for many people that step trips the §877A "covered expatriate" exit tax, a deemed sale of your worldwide assets the day before you go. Bulgaria, by contrast, is simply where you land: 10% flat personal tax, no wealth tax, no exit tax. This guide explains, honestly and with heavy caveats, how the US expatriation exit tax works in 2026, who it catches, the lasting sting of the §2801 succession tax, and where a genuine Bulgarian base fits — with a clear line between the Bulgarian side we advise on and the US filings that belong to US counsel.
Planning to renounce US citizenship or give up a green card and settle in Bulgaria? The exit tax is calculated on a snapshot taken the day before you expatriate — so the planning that matters happens while you are still a US person, alongside your US tax counsel. Once you have expatriated, the base is fixed and options narrow.

Why the US Taxes You to Leave
Start from the fact that makes the US unusual. Almost every country taxes you on the basis of where you live. The United States taxes you on the basis of who you are: a US citizen — and, while the green card is valid, a lawful permanent resident — is taxed on worldwide income no matter where in the world they actually reside. An American living in Sofia still files a US Form 1040, still files FBAR reports on foreign accounts, and is still caught by FATCA. Physical relocation changes nothing about the US claim.
Because the tax net is tied to status rather than presence, the only way to genuinely exit it is to shed the status — renounce the citizenship or formally abandon the green card. And that is precisely the act the US chose to tax. Under IRC §877A, leaving the US tax system is treated, for certain people, as a taxable event in its own right: a deemed sale of everything you own. Bulgaria taxes you to arrive at 10%; the US taxes you to depart. Understanding that asymmetry is the whole point of this article.
Who Is a "Covered Expatriate" in 2026
The exit tax does not hit everyone who renounces. It hits covered expatriates — and the definition is mechanical. Under IRC §877(a)(2), you are a covered expatriate if, on expatriation, you meet any one of three tests:
- The income-tax test. Your average annual net US income tax liability for the five years before expatriation exceeds an inflation-adjusted threshold — USD 211,000 for 2026 (up from USD 206,000 in 2025).
- The net-worth test. Your net worth is USD 2,000,000 or more on the expatriation date. This figure is not indexed, so ordinary asset inflation drags more people over it every year.
- The compliance test. You cannot certify, under penalty of perjury on Form 8854, that you have complied with all US federal tax obligations for the five years before expatriation.
Two points catch people out. First, the tests apply to long-term green-card holders just as they apply to citizens: if you held a green card in at least 8 of the last 15 tax years and then abandon it, you are a "long-term resident" who expatriates under §877A. Second, the compliance test is a trap of its own — failing to file Form 8854 at all makes you a covered expatriate automatically, regardless of your income or net worth. Someone with modest wealth can become covered purely on a paperwork failure.
The most common misconception: "I'll just move to Bulgaria and the US problem goes away." It does not. Until you formally renounce or abandon status, US citizenship-based taxation continues in full. And when you finally do expatriate, that is the moment §877A can bite. Relocation and expatriation are two different events — conflating them is the costliest error in this whole area.
The Mark-to-Market Exit Tax, Step by Step
If you are a covered expatriate, IRC §877A treats you as having sold all of your worldwide property at fair market value the day before your expatriation date. The built-in gain across everything you own — shares, funds, private company stock, real estate, crypto — is calculated as if realized, even though nothing has actually been sold and no cash has changed hands.
The net gain is then reduced by an exclusion. For 2026 that mark-to-market exclusion amount is USD 910,000 (up from USD 890,000 in 2025). Gain above the exclusion is taxed as if it had been realized in the normal way — long-term capital gains generally at long-term rates, subject to the ordinary US rules. On a large, appreciated, long-held portfolio, the number can be very substantial, and it lands as a real cash bill on paper wealth.
Not everything runs through the general mark-to-market rule. Three categories have their own treatment, and this secondary structure — the expatriation tax mechanics beyond the deemed sale — is where careful US planning earns its keep:
- Deferred compensation — split into "eligible" items (subject to a 30% withholding treatment on future payments if elected properly) and "ineligible" items (generally taxed as a present-value inclusion at expatriation).
- Specified tax-deferred accounts — an IRA and similar accounts are treated as fully distributed the day before expatriation, an immediate income inclusion rather than a capital-gains event.
- Non-grantor trust interests — subject to a 30% withholding on distributions rather than the deemed sale.
All of this is reported on Form 8854, the Initial and Annual Expatriation Statement, filed with your final US return. These are US filings that belong squarely with qualified US tax counsel — Innovires does not prepare or file them.

The §2801 Sting That Follows Your Heirs
Even after the exit tax is paid and citizenship is gone, covered-expatriate status leaves a shadow. Under IRC §2801, a US citizen or resident who later receives a gift or bequest from a covered expatriate is taxed on it — at the highest US estate and gift tax rate, currently 40%, above a small annual per-donee exclusion. The tax falls on the US recipient, not on the expatriate who made the gift, which reverses the usual intuition entirely.
Two features make this a genuinely lasting sting. Covered-expatriate status is permanent — it does not lapse with years — so a gift to a US-resident child or grandchild decades from now can still carry the 40% charge. And it is easy to overlook precisely because it surfaces long after the expatriation itself. If your heirs will remain US persons, the §2801 exposure belongs in the plan from day one. For the Bulgarian-side counterpart — how gifts and inheritances are treated once you and your assets are in Bulgaria — see our guide to Bulgarian inheritance and gift tax, which is a very different and far lighter regime.
Citizenship-Based Taxation and the US-Bulgaria Treaty
Here is the honest picture of the years before you expatriate, when you are Bulgarian-resident but still a US person. You are, in tax terms, standing in two systems at once:
- Bulgaria taxes you as a resident — 10% flat on personal income once you meet the tests in Article 4 ЗДДФЛ (the Personal Income Tax Act): 183 days in a 12-month period, or your centre of vital interests in Bulgaria.
- The US still taxes your worldwide income — because citizenship-based taxation does not care that you live in Sofia.
Genuine double taxation is softened, not by escaping the US, but by two mechanisms: the foreign tax credit, which credits Bulgarian tax paid against the US bill, and the foreign earned income exclusion (USD 132,900 for 2026) for earned income. But because Bulgaria's rate is so low, the foreign tax credit frequently does not fully absorb the US liability on passive and investment income — so the US typically remains the higher-tax layer until the day you actually expatriate.
What about the treaty? Contrary to a common assumption, a US-Bulgaria income tax treaty is in force (in effect since 2008), and it does useful work: residence tie-breaker rules and reduced withholding on cross-border dividends, interest and royalties. But for a US citizen it does not break the US claim, because of the treaty's saving clause — a standard provision under which the US reserves the right to tax its own citizens as if the treaty did not exist. So the treaty coordinates source taxation and supports the credit; it is not a route out of citizenship-based taxation. There is also no US-Bulgaria totalization agreement, so social-security positions are not coordinated. We cover the treaty mechanics in detail in our US-Bulgaria double tax treaty guide, and the day-to-day filing picture in moving to Bulgaria from the US.
The key distinction to hold onto: a treaty tie-breaker can make you Bulgarian-resident for treaty purposes and still leave you fully US-taxable as a citizen. Residence and citizenship are different levers, and only shedding the citizenship — with §877A waiting at that door — closes the US system for good.
Where Bulgaria Fits — a Clean, Flat Landing
No destination removes a US exit tax that is triggered by leaving the US system — the charge attaches to expatriation itself, not to where you go. What Bulgaria changes is the base you build on the other side, and for someone finally free of US worldwide taxation that base matters enormously:
- 10% flat personal income tax — the lowest flat rate in the EU, on worldwide income once you are Bulgarian tax resident under Article 4 ЗДДФЛ.
- 15% combined for a company — 10% corporate income tax plus 5% on dividends, if you run your business through a Bulgarian EOOD.
- No wealth tax — Bulgaria levies no annual tax on net worth, so the asset base you keep is not eroded year after year.
- No Bulgarian exit tax — should your life change again later, Bulgaria does not impose its own departure charge on individuals the way the US does.
All of this sits inside an EU member state that adopted the euro on 1 January 2026 and has been fully in Schengen since 1 January 2025 — a real jurisdiction with banking, treaties and EU protections, not an offshore mailbox. For a former US person, the appeal is exactly that it is ordinary: a low, flat, defensible tax home. If you are still weighing where to settle, our country-selection framework is the companion piece, and our Bulgaria tax residency guide covers the destination in full.
Sequencing It — Two Countries, One Timeline
Because the §877A charge crystallizes on a snapshot the day before you expatriate, and because covered status is set on the expatriation date, the sequence has to be planned across both countries at once:
- Assess covered status early — with US counsel, run the three tests before you commit to a date, and understand how the net-worth and income-tax thresholds sit against your position.
- Value and structure before expatriation — the deemed sale is computed on the value at that date, so any restructuring, gifting or realization decisions are US-side moves made while you are still a US person.
- Establish genuine Bulgarian residence — a real home and life under Article 4 ЗДДФЛ, documented with a tax residency certificate and a filed first-year return, so the new position is evidenced rather than assumed.
- Keep filing until the exit is formal — the US obligation runs right up to renunciation or abandonment; the Bulgarian obligation begins when you become resident. For a period, both are live.
Founders in particular should read this alongside our guides on relocating before selling a company and building a post-exit wealth base in Bulgaria, because a company sale, the exit tax and the move should be sequenced together, not treated as three separate problems.
US Covered Expatriate vs Bulgaria — Side by Side
| Factor | US covered expatriate (on exit) | Bulgaria (after you land) |
|---|---|---|
| Basis of taxation | Citizenship — worldwide, wherever you live | Residence — 183 days or vital interests |
| Exit / departure tax | §877A deemed sale of worldwide assets | None |
| Gain exclusion on exit | USD 910,000 (2026), then taxed as realized | Not applicable — no exit tax |
| Personal income tax | Graduated federal rates on worldwide income | 10% flat |
| Annual wealth tax | None federally, but net-worth test at exit | None |
| Company burden | US corporate tax plus taxed distributions | 15% combined (10% + 5%) |
| Succession follow-on | §2801 — 40% on US recipients of your gifts | Light Bulgarian inheritance/gift regime |
The right-hand column is not merely lower on the income line — it removes the entire architecture of citizenship-based taxation, the deemed-sale exit charge and the §2801 follow-on that the left-hand column carries. That structural shift, not the headline rate alone, is why a genuine Bulgarian base appeals to Americans who have decided the US system no longer fits their life.
Doing It Properly — Substance and Two Sets of Advisers
The Bulgarian saving only holds if the residence is real, and the US exit only holds if it is done to the letter. Both sides turn on genuine facts and clean documentation:
- A real home and life in Bulgaria — where you actually live. Establishing your centre of vital interests in Bulgaria is what makes the residency defensible under Article 4 ЗДДФЛ.
- A correct, complete US exit — five years of clean compliance, a properly filed Form 8854, and the §877A computation done by US counsel. Cutting corners here is what turns a modest position into automatic covered status.
- Documented Bulgarian residence — a tax residency certificate and a filed first-year return, so the position is evidenced if either tax authority asks later.
Bulgaria taxes personal income at 10% flat under Article 4 ЗДДФЛ once you meet the 183-day or centre-of-vital-interests test, and a Bulgarian company at the 15% combined framework — but those rates only protect you if the residence behind them is genuine. Innovires handles the Bulgarian side end to end and coordinates with your US tax counsel on timing; we do not replace them.
Common questions before booking:
Will Innovires file my US expatriation return? No. The §877A exit tax, Form 8854 and the §2801 succession tax are US matters for qualified US tax counsel. We handle the Bulgarian residence, company and treaty side and coordinate the timeline with them.
Can I avoid covered-expatriate status? Sometimes, with early US planning — but never by hiding assets or skipping filings. The compliance test means a missed Form 8854 makes you covered outright.
Do I have to renounce to enjoy Bulgaria's 10%? No. You can be Bulgarian tax resident while still a US person — but you keep filing US returns until you formally expatriate, and the US usually remains the higher-tax layer until then.
What does Bulgaria charge me afterward? 10% flat on personal income, a 15% combined company framework, no wealth tax and no exit tax. VAT registration for a company becomes mandatory at EUR 51,130 of taxable turnover.
When This Is Not for You
An honest framework has to be able to say no. Coordinating a US expatriation with a Bulgarian move is the wrong call when:
- You are not ready to give up US citizenship. If you want to keep the passport, you keep the worldwide filing — a Bulgarian move lowers your local rate but does not end the US system. That can still be worthwhile; just be clear it is not an exit.
- Your US tax affairs are not clean. Without five clear years of compliance you risk automatic covered status. Fix the compliance first, with US counsel, before contemplating expatriation.
- Your heirs will stay US persons and your estate is large. The §2801 follow-on can outweigh the income-tax saving; the plan has to price it in.
- You want a zero-tax fantasy. Bulgaria is low, flat and defensible — not nil — and the US exit is a real, paid event. If your plan depends on paying nothing anywhere, it is not a plan, it is an exposure.
