How does Swiss-Bulgarian social security work?

Switzerland is part of the EU social-security coordination system through the EU-Switzerland Agreement on the Free Movement of Persons. Regulation (EC) 883/2004 has applied to Switzerland since 1 April 2012. This means full coordination with Bulgaria: contribution periods can be totalised for pension entitlement, posted workers can hold an A1 certificate to stay in their home system, and only one country's social security applies to a given activity at a time. In practical terms, the Swiss-Bulgarian setup behaves as if Switzerland were an EU member state for social-security purposes.

What happens to my Pillar 2 (BVG/LPP) if I move to Bulgaria?

Because Bulgaria is an EU member state, the EU/EFTA emigration rules apply. The mandatory portion (Obligatorium) of your second pillar must remain in Switzerland in a vested-benefits account (Freizügigkeitskonto) until the legal retirement age. The supplementary portion (Überobligatorium) can be paid out as a lump sum on emigration. The lump sum is taxed at source by the canton where the pension institution is located; the Switzerland-Bulgaria tax treaty governs how that interacts with Bulgarian tax. Plan the timing carefully — your Swiss tax adviser models the canton-by-canton effect.

What is the effective tax on profit taken out of a Bulgarian company?

Profit distributed by a Bulgarian EOOD or OOD to its owner is taxed at a combined 15 percent — 10 percent corporate income tax on the company plus 5 percent dividend withholding tax on the distribution. There is no further owner-level income tax on the dividend. For a Swiss owner who has become a Bulgarian tax resident, that 15 percent is the all-in tax cost of taking profit out of the company. A registered Bulgarian freelancer reaches an effective rate of about 7.5 percent through a 25 percent statutory expense allowance.

Moving to Bulgaria from Switzerland: Tax & Residency (2026)

Q: Do Swiss citizens need a visa to move to Bulgaria?

No. Under the EU-Switzerland Agreement on the Free Movement of Persons, Swiss nationals are treated on the same footing as EU citizens for residence in Bulgaria. They do not need a Type D long-stay visa. They enter visa-free, and to stay longer than three months they register at the Migration Directorate and receive an EU-equivalent residence certificate. This is the smoothest entry route of any non-EU country and a meaningful advantage over Canadian or American applicants.

Q: Do Swiss residents stop paying Swiss tax after moving to Bulgaria?

Yes. Switzerland taxes individuals on the basis of residence — federal, cantonal and communal. Once you genuinely transfer your tax domicile out of Switzerland and become a Bulgarian tax resident, Switzerland stops taxing your worldwide income. Switzerland generally continues to tax Swiss-source items such as Swiss real-estate income, dividends from Swiss companies (subject to treaty relief), and Pillar 2 lump-sum withdrawals taxed at source by the canton of the pension fund.

Q: Is there a tax treaty between Switzerland and Bulgaria?

Yes. A new income and capital tax treaty between Switzerland and Bulgaria was signed in 2012 and entered into force on 1 January 2014, replacing the 1991 treaty. It allocates taxing rights, provides a residence tie-breaker for the transition year and eliminates double taxation through the credit method. Withholding tax rates were reduced under the new treaty — interest is capped at 5 percent (down from 10 percent under the 1991 treaty).

Q: Why move to Bulgaria from Switzerland?

Four reasons. First, the headline rates — 10 percent flat personal tax, 10 percent corporate tax, 5 percent dividend tax (15 percent combined), versus combined Swiss federal-cantonal-communal personal rates that typically reach 22 to 46 percent depending on the canton. Second, EU member state with the euro adopted from 1 January 2026 — banking, contracts and pricing are now euro-denominated. Third, Swiss nationals enjoy EU-equivalent residence rights in Bulgaria — no Type D visa required. Fourth, the Swiss-Bulgarian tax and social-security frameworks (2014 treaty plus EU coordination from 2012) are settled and work in practice.

Of all the non-EU jurisdictions our clients move from, Switzerland is the easiest. Swiss nationals enjoy EU-equivalent residence rights in Bulgaria — no Type D visa, no consulate queue, no work-permit category to qualify under. Switzerland is already inside the EU social-security coordination system through the Free Movement of Persons agreement, so your AHV history is not lost. And the Switzerland-Bulgaria tax treaty in force since 2014 is modern and workable. The result is that, for a Swiss resident relocating to Bulgaria, almost all of the heavy lifting is on the Bulgarian side — which is what we do.

This guide is written for Swiss residents — Swiss nationals and EU citizens long-term resident in Switzerland — who are weighing a move to Bulgaria. We describe the Swiss-side framework adequately so you know what to discuss with your Swiss Treuhänder or fiduciaire, and then concentrate on the Bulgarian-side build: residence registration, company or freelancer setup, banking, and the tax registrations that make the 10 percent flat rate actually yours. That is the part we run.

Scope: we are a Bulgarian law firm. Your Swiss exit, the Pillar 2 lump-sum withdrawal, and the canton-level paperwork are handled by your Swiss adviser. We coordinate with them and design the Bulgarian arrival so the two sides line up.

Why Swiss Residents Are Moving to Bulgaria

The pitch is short. For an entrepreneur or independent professional, the difference in tax cost between Switzerland and Bulgaria is large enough to change the answer to every other question.

Headline rates. Bulgaria applies a 10 percent flat personal income tax, a 10 percent corporate tax, and a 5 percent dividend tax — a 15 percent combined effective rate on profit distributed to the owner of a Bulgarian company. Swiss combined federal-cantonal-communal personal rates typically reach 22 to 46 percent depending on canton and commune; Swiss corporate rates run roughly 12 to 21 percent combined, again with wide canton-to-canton variation.
Bulgaria is in the eurozone from 1 January 2026. Banking, contracts and pricing are now euro-denominated; the fixed conversion rate against the lev is 1 EUR = 1.95583 BGN and is final.
EU member state with the rule book Switzerland already knows. Swiss residents transitioning to Bulgaria do so under familiar EU frameworks for social security, treaty relief and free movement of capital. There is very little novel paperwork.
EU-equivalent residence for Swiss citizens. Unlike Canadians or Americans, Swiss nationals do not need a Type D long-stay visa to establish residence here. We describe this in detail below — it is the single biggest practical advantage Swiss applicants have.

Residence in Bulgaria: the Swiss Advantage

This is where the Swiss route diverges sharply from the Canadian, American or UK route. Under the EU-Switzerland Agreement on the Free Movement of Persons (AFMP), Swiss nationals enjoy substantially the same residence rights in EU member states as EU citizens. In Bulgaria the practical effect is:

No Type D long-stay visa required. You do not apply at a Bulgarian embassy or consulate before travelling.
Visa-free entry on your Swiss passport, with the right to remain for up to three months without any registration.
To stay longer, you register at the Migration Directorate for an EU-equivalent residence certificate. The grounds available to you are the same as those open to EU citizens — economic activity (employment, self-employment, company shareholder), sufficient resources, study, family member of an EU/Swiss citizen.
The certificate is initially issued as a short-term residence (typically up to five years) and, after five years of continuous lawful residence, converts to long-term/permanent residence on application.

What this means in practice: we set you up with the activity that supports your residence application (most commonly a Bulgarian EOOD or a registered freelance activity), prepare the file for the Migration Directorate, and accompany you to filing. There is no consulate appointment in Bern or Geneva to wait for. For most of our Swiss clients, residence is settled within a few weeks of arrival.

EU citizens already resident in Switzerland. If you are an EU citizen (German, Italian, French, Portuguese, etc.) currently tax-resident in Switzerland, your route to Bulgaria is even simpler — you are an EU citizen exercising your own treaty rights. Your Swiss exit is the work; the Bulgarian arrival is straightforward.

Leaving the Swiss Tax System

Switzerland taxes individuals on the basis of residence, not citizenship — at three levels (federal, cantonal, communal). Once you genuinely transfer your tax domicile out of Switzerland and establish Bulgarian residence, Switzerland stops taxing your worldwide income. From that point Switzerland continues to tax only specific Swiss-source items, principally Swiss real-estate income, dividends from Swiss companies (subject to treaty relief), and Pillar 2/3a lump-sum withdrawals taxed at source by the canton of the pension fund.

Important framing for the move:

No general Swiss exit tax on private movable assets. Switzerland does not levy a comprehensive deemed-disposition tax on emigration. Unrealized capital gains on private securities are not subject to a Canadian-style departure tax — which makes the timing of your move materially simpler than for a Canadian or American counterpart.
No Wegzugsbesteuerung on substantial shareholdings either. Unlike Germany (with its s.6 AStG exit charge on substantial holdings in corporations), Switzerland does not impose a federal-level emigration tax on shares held by individuals. The Bulgarian arrival is therefore not held hostage to a six- or seven-figure exit bill on the way out.
De-registration. You de-register at your Swiss Gemeinde / commune / comune on departure and your residence status changes from the date of de-registration; this is also the cut-off the Swiss tax authority uses to issue your final assessment.
Lump-sum taxation regime. If you have lived in Switzerland under the imposition d'après la dépense / Pauschalbesteuerung regime, that regime ends with your departure; no special action is needed beyond the regular exit administration.
Automatic exchange (CRS). Switzerland and Bulgaria both apply the OECD Common Reporting Standard, so your move is visible to both tax authorities — another reason to make the exit and the Bulgarian arrival administratively clean.

The exit paperwork — final returns, de-registration, Pillar withdrawals — is the part your Swiss Treuhänder handles. Our role is to make sure the Bulgarian arrival sits cleanly behind it, so the Swiss tax authority sees a real foreign tax domicile on the other side.

Pillar 2 and Pillar 3a on Emigration to Bulgaria

Because Bulgaria is an EU member state, the EU/EFTA emigration rules apply to your second pillar — and they are stricter than the rules for someone leaving Switzerland for, say, the United States or Asia.

Pillar 2 — occupational pension (BVG/LPP)

The mandatory portion (Obligatorium) must remain in Switzerland in a vested-benefits account (Freizügigkeitskonto / compte de libre passage) until the legal retirement age. You cannot take it out as cash on emigration to Bulgaria.
The supplementary portion (Überobligatorium) can be paid out as a lump sum on definitive departure.
The cash payout is taxed at source by the canton of the pension institution. Choice of vested-benefits foundation can therefore matter; the canton-by-canton lump-sum rate is the kind of decision your Swiss adviser models.
The Switzerland-Bulgaria tax treaty governs whether the Swiss withholding is final or whether Bulgaria has a residual claim. Coordinate with your Swiss adviser before withdrawing.

Pillar 3a — private pension

On definitive departure you can typically withdraw your Pillar 3a as a lump sum.
The withdrawal is taxed at source by the canton where the 3a foundation has its seat — again, the choice of foundation has tax consequences.
Once you are a Bulgarian tax resident, any Swiss-source pension income is governed by the 2014 treaty and Bulgarian domestic rules.

Plan the Pillar 2 timing. If you withdraw the Überobligatorium before you de-register and become Bulgarian tax resident, the entire lump sum is normally Swiss-taxable at the higher rate of the canton of your last Swiss residence. If you withdraw after, the lump sum is taxed at source by the canton of the foundation, often a more favourable result. This is exactly the kind of decision your Swiss adviser should model before you set a departure date.

The Switzerland-Bulgaria Tax Treaty (2014)

A new income and capital tax treaty between Switzerland and Bulgaria was signed in 2012 and entered into force on 1 January 2014, replacing the 1991 treaty. The Swiss Federal Tax Administration's overview page is here.

The treaty does the three things any modern double-tax treaty does:

Allocates taxing rights between Switzerland and Bulgaria for each type of income — employment, business profits, dividends, interest, royalties, pensions, capital gains.
Provides a residence tie-breaker for the year you move (permanent home → centre of vital interests → habitual abode → nationality → mutual agreement).
Eliminates double taxation through the credit method.

One material upgrade compared to 1991: the maximum withholding tax on interest dropped from 10 percent to 5 percent. Switzerland does not levy a domestic withholding tax on outbound royalties to non-residents, so royalty WHT between the two states is effectively zero. For more detail on how Bulgaria's treaty network works in practice see our pillar on Bulgaria's double tax treaties.

For most of our Swiss clients this section produces real relief. Switzerland is part of the EU social-security coordination system through the AFMP — Regulation (EC) 883/2004 has applied to Switzerland since 1 April 2012 (see the BSV/FSIO overview).

The practical consequences in a Swiss-Bulgarian setup:

One country at a time. Only one country's social security applies to a given activity at a time, and the rules of Regulation 883/2004 decide which.
Posted workers. If you continue to perform work for a Swiss employer from Bulgaria, you may be able to remain in the Swiss system temporarily under an A1 certificate; conversely a Bulgarian-domiciled freelancer or EOOD owner serving Swiss clients pays into the Bulgarian system and obtains an A1 in Bulgaria when needed.
Totalisation. Your AHV/AVS contribution years are not wasted; periods in Switzerland and Bulgaria can be combined for pension entitlement purposes.
Cross-border telework is now expressly covered by an EU-wide framework agreement that Switzerland and Bulgaria have both joined — useful for clients who want to spend part of the year in each country without switching social-security regimes.

Bulgarian social-security contributions are much lower than Swiss in absolute terms. The combined employer-and-insured contribution rate sits at around 27.8 percent of insurable income for a standard third-category worker, and the insurable income is capped at a statutory monthly maximum. So for higher earners the effective contribution stops growing once you cross the cap — unlike the Swiss combined AHV/IV/EO/ALV rates, which run without a meaningful upper cap. We model the exact numbers, and the current 2026 maximum insurable monthly income, when we structure your EOOD or freelance setup.

Tax Comparison: Switzerland vs Bulgaria (2026)

Tax category	Switzerland (2026)	Bulgaria (2026)
Personal income tax — federal	Progressive, top federal bracket 11.5 percent	10% flat
Personal — combined fed + cantonal + communal	Roughly 22–46% depending on canton and commune	10%
Corporate tax (combined)	Roughly 12–21% depending on canton	10%
Dividend tax on owner	Partial relief regime (about 70% of dividend taxed at marginal rate)	5%
Combined tax on profit to owner	Varies by canton; typically well above 25% all-in	15% (10% + 5%)
Capital gains — private movable assets	Generally tax-free at federal level for private investors	0% on EU/EEA-regulated-market shares for individuals; 10% on shares outside the EU/EEA regulated markets
Wealth tax	Yes — cantonal/communal, varies	None
Exit tax on emigration	None (no general deemed disposition)	None
Residence basis	Residence-based	Residence-based (183 days or centre of vital interests)

The headline contrast is the dividend / owner-payout column. For a Swiss owner-manager taking profit out of a Swiss company, the all-in cost — corporate income tax plus the partially-relieved dividend tax — runs well above 25 percent in most cantons. For the same person operating through a Bulgarian EOOD as a Bulgarian tax resident, the all-in cost is 15 percent and there is no further owner-level tax on the dividend. Per 100,000 EUR of distributed profit, the saving sits in five figures.

Freelancer or EOOD — How We Set You Up in Bulgaria

Once your Swiss exit is settled, the Bulgarian side is two decisions: residence ground and income vehicle. We make both with you.

Registered freelancer (свободна професия)

Effective tax rate around 7.5 percent — a 25 percent statutory expense allowance means the 10 percent flat tax applies to only 75 percent of gross income.
Simple to register, low compliance cost, fast to set up.
Personal liability — no separate legal entity.
Suitable for independent professionals — software engineers, consultants, designers, advisers — with moderate income and Swiss/EU clients.

Single-member company (EOOD)

10 percent corporate tax on profit, plus 5 percent dividend tax on distributions — a 15 percent combined rate, with no further owner-level tax in Bulgaria.
Limited liability, a separate legal person, professional structure for Swiss/EU clients and banks, ability to retain profit inside the company.
Monthly accounting and annual financial statements — we run this with our in-house accounting partners.
Suitable where income is higher, you want to retain capital, or you need a vehicle for Swiss-Bulgarian contracts.

Both routes support your Migration Directorate residence application. For a detailed framework see our guide on EOOD vs freelancer in Bulgaria.

Living in Bulgaria as a Swiss Resident — Practical Notes

Banking. Bulgarian banks accept Swiss-passport individuals and Swiss-sourced funds with the standard KYC documentation. With the euro adopted from 1 January 2026, your Bulgarian account is euro-denominated and SEPA-integrated — funds move between a Swiss UBS / Raiffeisen / Postfinance account and your Bulgarian account inside the eurozone.
Healthcare. Once you take up Bulgarian residence on an economic ground (EOOD, freelance, employment), you enter the Bulgarian national health-insurance system via your contributions; private top-up insurance is widely available and inexpensive by Swiss standards. EU coordination rules govern any short-term Swiss medical claims under EHIC equivalents.
Driving and identity. Swiss driving licences are accepted in Bulgaria; conversion to a Bulgarian licence becomes available once you hold a Bulgarian residence permit. Bulgarian residents receive a personal identification number (EGN / Foreigner's PIN) we obtain as part of the residence file.
Schools. Sofia has English-, German- and French-language schools that work well for Swiss families; we can introduce you to admissions teams once we know your timing.
You do not lose Swiss citizenship by emigrating — only Swiss tax residency changes. Your Swiss passport remains valid and you can return at any time (with separate tax consequences on re-entry).

Setup Timeline for a Swiss Resident

Month -2: initial call with us; we map the Bulgarian setup (residence ground, EOOD vs freelancer, banking, accounting). In parallel, your Swiss Treuhänder models the final Swiss tax year and any Pillar 2/3a withdrawal timing.
Month -1: documents prepared on both sides. Swiss de-registration paperwork ready; Bulgarian EOOD or freelance file drafted; lease or accommodation arranged in Bulgaria.
Departure date: de-register at your Swiss Gemeinde / commune. Travel to Bulgaria.
Weeks 1–4 in Bulgaria: we file your residence application at the Migration Directorate, register the EOOD or freelance activity at the Commercial Register, open the Bulgarian bank account, register with the National Revenue Agency (NRA), obtain your Foreigner's PIN, and — when you need it for the Swiss cantonal tax office — request an NRA tax-residency certificate to confirm your Bulgarian residence under the treaty.
Month 2–3: first invoices issued from the Bulgarian structure. Monthly accounting runs.
Spring of the following year: file the Bulgarian annual return; your Swiss adviser closes the final Swiss assessment and any Pillar 2/3a refund process under the treaty.

Common Mistakes Swiss Residents Make

1. Drawing Pillar 2 before establishing Bulgarian residence

The Überobligatorium lump sum is taxed at source by the canton involved. If you draw it while still Swiss-resident, the tax base is your last canton of residence. Sequencing matters; coordinate with your Swiss adviser.

2. Underestimating the residential-substance test in Bulgaria

EU-equivalent residence rights make the paperwork easy, but Bulgarian tax residency still requires real presence — 183 days, or your centre of vital interests in Bulgaria. Visiting Sofia twice a year and keeping a Geneva apartment as your real home does not get you to 10 percent.

3. Keeping a substantive Swiss home indefinitely

A Swiss flat held in your name, used as your primary residence in the cantonal records, is exactly the kind of fact that lets the Swiss tax authority continue to assert residence. Where the move is genuine, the home arrangement should reflect it.

4. Assuming the new EOOD removes the Swiss filing for the year of departure

You still owe a final Swiss assessment for the part-year that you were Swiss-resident, plus the Pillar withdrawal taxation. Budget for this; do not assume the move closes the books on day one.

5. Treating Bulgaria as a "no questions asked" jurisdiction

It is not. Bulgaria's low rates are ordinary EU tax law, but you must be a genuine resident with real substance. Token presence is not residency.

Common questions before booking:

Is this legal? Yes. Bulgaria's flat tax is ordinary EU tax law, in place since 2008. Switzerland's residence-based system means a genuine emigrant simply ends Swiss tax residency.

Do we speak German, French, Italian? Our team works in English; we coordinate in German and French with Swiss advisers as needed. All documents in Bulgaria are issued in Bulgarian; we translate everything you need.

Do you handle the Swiss exit? No — your Swiss Treuhänder handles the Swiss side. We coordinate with them so the two sides align.

What does it cost? Full Bulgarian relocation packages start from EUR 2,000 plus state fees. First consultation is free.

Frequently Asked Questions

Do Swiss citizens need a visa to move to Bulgaria? +

No. Under the EU-Switzerland Free Movement of Persons agreement, Swiss nationals are treated like EU citizens for residence in Bulgaria. You enter visa-free, and to stay longer than three months you register at the Migration Directorate for an EU-equivalent residence certificate. No Type D visa, no consulate appointment.

Do Swiss residents stop paying Swiss tax after moving to Bulgaria? +

Yes, on worldwide income, once you genuinely transfer your tax domicile out of Switzerland and become Bulgarian tax-resident. Switzerland keeps taxing only specific Swiss-source items — Swiss real-estate income, Swiss-company dividends (subject to treaty relief), and Pillar 2/3a withdrawals taxed at source by the canton.

Is there a tax treaty between Switzerland and Bulgaria? +

Yes. A new treaty signed in 2012 entered into force on 1 January 2014, replacing the 1991 treaty. It allocates taxing rights, provides a residence tie-breaker, and removes double taxation via the credit method. Withholding tax on interest was cut from 10% to 5%; Switzerland does not levy a domestic royalty WHT, so royalty WHT is effectively zero.

How does social security work between Switzerland and Bulgaria? +

Switzerland is part of the EU social-security coordination system through the AFMP — Regulation 883/2004 has applied since 1 April 2012. Only one country's social security applies at a time, posted workers can use A1 certificates, and AHV/AVS contribution periods are totalisable with Bulgarian contributions for pension purposes. Book a free consultation and we will explain how it applies to you.

What happens to my Pillar 2 (BVG/LPP) on emigration? +

Because Bulgaria is an EU member state, the EU/EFTA rules apply: the mandatory portion must remain in a Swiss vested-benefits account until legal retirement age; only the supplementary portion can be drawn as a lump sum. The lump sum is taxed at source by the canton of the pension institution; choice of foundation matters. Coordinate timing with your Swiss adviser.

What about Pillar 3a private pension on emigration? +

On definitive departure from Switzerland you can typically withdraw your Pillar 3a as a lump sum. The withdrawal is taxed at source by the canton where the foundation has its seat. Once you are a Bulgarian tax resident, the Bulgarian treatment of any Swiss-source pension income is governed by the Switzerland-Bulgaria treaty and Bulgarian domestic rules. Coordinate the withdrawal with your Swiss adviser.

What is the effective tax on profit taken from a Bulgarian company? +

Profit distributed from a Bulgarian EOOD to its owner is taxed at 15% combined — 10% corporate tax + 5% dividend tax. No further owner-level income tax in Bulgaria. A registered freelancer is taxed at roughly 7.5% effective via the 25% statutory expense allowance.

Why move to Bulgaria from Switzerland? +

Four reasons: 10% flat / 15% combined vs Swiss combined rates of 22–46%; eurozone from 2026; EU-equivalent residence for Swiss nationals (no Type D visa); a settled 2014 tax treaty and EU social-security coordination since 2012. Ask us and we will model your specific situation.
