Moving to Bulgaria from Sweden: Tax Comparison & Legal Steps (2026)

Roughly 52% maximum marginal rate in Sweden. 10% flat in Bulgaria. 15% combined on company profits versus around 45% in Sweden. For Swedish entrepreneurs, founders and investors, the difference is one of the largest inside the European Union - and since 1 January 2026, Bulgaria has been a euro country, removing the currency friction that once complicated Nordic relocations.

But moving from Sweden is not only a tax exercise. You must file an SKV 7665 notification with Skatteverket, deregister from folkbokföringen (the population register), plan around the ten-year rule on share gains, settle your Försäkringskassan coverage, and handle your Swedish pension treatment under the SE-BG double tax convention. Miss a step and you risk dual tax residency and an unexpected assessment from Skatteverket several years after you thought you had left.

This guide walks through the full process - from your last visit to the tax office to your first filing with the Bulgarian NRA. It is written by a Bulgarian law firm that handles Nordic relocations regularly. Where Swedish rules are technical or carry a multi-year tail, we flag them clearly and recommend coordination with a Swedish skatterådgivare.

Why Swedes Leave: The 2026 Pressure Points

Sweden's municipal tax decreased on average in 2026 - the total municipal rate is now 32.38%, down a few hundredths of a point from 2025. But the overall burden on mobile, high-earning professionals remains among the heaviest in Europe:

• Municipal tax of 28.93% to 35.65% depending on commune - the lowest rate is in Österåker, the highest in Dorotea (2026 figures, Statistics Sweden).
• A 20% state income tax on top of municipal tax, kicking in above approximately SEK 660,400 of annual earned income for those under 66 (2026 brackets).
• Maximum marginal rate around 52% on salary and self-employment income above the state-tax threshold.
• Capital gains on listed securities: 30%. Capital gains on unlisted qualifying shares (fåmansföretag - the classic entrepreneur company): up to 58% total on the "ordinary income" portion above the annual K10 threshold, under the widely criticised 3:12 rules.
• Dividend withholding on foreign owners: 30% standard, often reduced to 15% or 0% under tax treaties - relevant if you become Bulgarian resident and hold Swedish shares.
• Ten-year rule on share gains (Chapter 3 §19 IL): Sweden preserves the right to tax share sales for up to ten calendar years after emigration, subject to treaty limits.
• Employer social contributions of 31.42% (arbetsgivaravgifter) on top of gross salaries - a heavy cost that effectively sits on the employee.

For Swedish AB founders, consultants, IT professionals, crypto investors and remote workers, the calculation has become straightforward. Bulgaria - inside the EU, now a euro country, Schengen member since January 2025 - offers one of the cleanest alternatives in Europe.

Step 1 - Swedish Tax Deregistration (SKV 7665)

Sweden links tax residency to folkbokföring - the population register. When you are registered in folkbokföringen you are generally treated as unlimited tax resident in Sweden. When you deregister as having moved abroad, your unlimited tax liability ends on the effective date of departure (though the ten-year rule on share gains continues to apply - more on that below).

The SKV 7665 process

1. Download form SKV 7665 (Anmälan - Flyttning till utlandet / Notification, Moving Abroad) from skatteverket.se. The form is available in Swedish and English.
2. Submit at least one week before departure. List all family members moving with you - each person must be included on the notification.
3. Trigger condition: you must submit the form if you are moving abroad for at least one year. Shorter absences do not usually break Swedish tax residency.
4. Population register update: Skatteverket registers you in folkbokföringen as utflyttad (emigrated). Your personnummer remains valid for life, but your address in the register becomes "abroad".
5. Notify Försäkringskassan (the Swedish Social Insurance Agency) and your private pension providers. Under EU Regulation 883/2004, social security coordination is then handled between Sweden and Bulgaria.
6. Keep your proof of deregistration. You will need it to close Swedish health care links, update banks, close ISK (Investeringssparkonto) and KF (kapitalförsäkring) accounts or convert them, and to invoke the SE-BG treaty.

Your final Swedish tax return

For the year of departure you file a normal Swedish income tax return (inkomstdeklaration 1) covering the period you were a Swedish resident, reporting your worldwide income for that period. After that, if you keep Swedish-source income (rental income from a Swedish property, for example, or Swedish directorships), you file as a limited taxpayer on the SINK or non-resident return.

Step 2 - The Swedish Ten-Year Rule on Share Gains

Sweden has no classical exit tax on unrealised capital gains. A proposal floated by Skatteverket in 2017 (30% tax on latent gains above SEK 100,000 for individuals who had been Swedish resident for five of the last ten years) was heavily criticised and abandoned. A 2022 government inquiry reopened the file but no legislation has been enacted. As of 2026, Sweden has not implemented an exit tax.

Instead, Sweden relies on the ten-year rule in Chapter 3 Section 19 of the Swedish Income Tax Act (Inkomstskattelagen):

• The rule: individuals who have been Swedish tax residents can be taxed on gains from the sale of shares and certain other securities if they were Swedish resident at any point during the ten calendar years preceding the sale.
• Scope: originally targeted at Swedish shares; extended over time to foreign shares and qualifying shares (fåmansföretagsandelar) of Swedish entrepreneurs.
• Treaty overlay: most of Sweden's tax treaties limit the ten-year rule, typically allowing Sweden to tax only gains on substantial shareholdings in Swedish companies within a shorter window (often 5-7 years post-emigration). The SE-BG treaty and the OECD Multilateral Instrument determine how this applies in practice.

Practical implication

If you own qualifying shares (fåmansföretag / owner-managed Swedish company) and plan to sell them shortly after leaving Sweden, you remain within Sweden's extended reach under the ten-year rule - with the exact treaty cap depending on the buyer, the company's assets, and the time elapsed. Do not sell the Swedish operating company in the first years after leaving without a Swedish tax opinion. For long-term holders who intend to keep their shares or who sell after the treaty window, the rule is largely a reporting obligation.

Step 3 - Bulgaria Residence as an EU Citizen

Swedish citizens are EU citizens. You enter Bulgaria freely - no visa, no border queue (Bulgaria joined Schengen in January 2025). You may stay up to 90 days without any registration. For long-term residence you register at the Migration Directorate (Дирекция Миграция) under the Ministry of Interior.

Four grounds for EU prolonged residence

To obtain a prolonged residence certificate (valid up to 5 years), you must prove one of four grounds:

1. Company owner or self-employed - you own a registered Bulgarian EOOD/OOD or are a registered freelancer.
2. Employee - you have an employment contract with a Bulgarian employer.
3. Self-sufficient person - private health insurance valid in Bulgaria plus sufficient funds (approximately EUR 5,100 for the year).
4. Family member of a resident spouse, partner, or parent/child.

For most Swedish relocators - AB founders, consultants, IT professionals - ground 1 is the cleanest route: register a Bulgarian EOOD and use the shareholding as your basis for residence.

Fees and timeline

Residence fees: EUR 7 for a paper certificate, EUR 18 for a plastic residence card (standard ~30 days), or EUR 36 for the expedited 3-business-day issue. Persons under 16 or over 70 are exempt. Your LNCH number is issued with the residence certificate.

Tax Comparison: Sweden vs Bulgaria (2026)

A side-by-side view of the figures that actually matter:

Sweden-Bulgaria Double Tax Treaty

Sweden and Bulgaria are bound by a double tax convention in force since the 1990s, now modernised by the OECD Multilateral Instrument (MLI) which adds principal-purpose and beneficial-owner tests on top of the original text. You can consult the Bulgarian Ministry of Finance treaty list at minfin.bg and Skatteverket's guidance at skatteverket.se.

Key principles

• Residence tie-breaker: permanent home → centre of vital interests → habitual abode → nationality → mutual agreement. Once you settle in Bulgaria with your family and economic activity, you become a Bulgarian resident under the treaty.
• Elimination of double taxation: credit method. Bulgaria, as residence state, taxes your worldwide income at 10% personal / 10% corporate / 5% dividend and credits any Swedish tax withheld under the treaty caps.
• Business profits: taxable only in the state of residence unless a permanent establishment (PE) exists in the other state.
• Employment income: taxed where the work is physically performed, with a 183-day rule for short-term assignments.
• Swedish real estate income: Sweden retains the right to tax rental income and gains from Swedish property.
• Pensions: private pensions are generally taxable in the state of residence (Bulgaria, at 10%); Swedish government pensions typically remain taxable in Sweden.
• Ten-year rule interaction: the treaty caps (as modified by the MLI) determine how long Sweden can tax share gains of former residents. Confirm with your Swedish advisor.

ISK and KF Accounts After Leaving

Swedes hold a significant share of their investments in two flat-taxed wrappers: the Investeringssparkonto (ISK) and the Kapitalförsäkring (KF). Both are taxed on a standardised basis at a schablon rate linked to the Swedish statslåneräntan. Once you cease to be a Swedish resident:

• ISK: the standard-income taxation no longer applies from the year after you emigrate. Most Swedish brokers (Avanza, Nordnet, SEB, Handelsbanken) will require you to close or convert the account because the product is tied to Swedish residence.
• KF (endowment insurance): the capital insurance can often be kept, but the Swedish insurer may restrict deposits, block new contributions, or - for some providers - require termination on emigration. Confirm with your insurer before the move.
• Transition planning: many relocators convert ISK/KF holdings to an ordinary Swedish or foreign brokerage account in the final year of Swedish residence, then transfer custody to an EU broker (Interactive Brokers, DEGIRO, Lynx) after the move.
• Bulgaria side: Bulgaria has no equivalent wrapper. Ordinary capital gains on EU/EEA regulated-market shares are exempt under Art. 13(1)(3) ЗДДФЛ for individuals - a meaningful benefit. US-market gains (NYSE/NASDAQ) are taxable at 10%.

Swedish Property After Leaving

If you keep a house, apartment, or summer house (fritidshus) in Sweden, your tax exposure shifts but does not disappear:

• Swedish property tax / fee (kommunal fastighetsavgift): continues to apply regardless of your residence, assessed on the property's tax value.
• Rental income: remains taxable in Sweden as Swedish-source income at 30% on net rental income for non-residents, collected via SINK or the non-resident return.
• Capital gains on sale: Sweden retains the right under the SE-BG treaty to tax gains on Swedish immovable property - 22% effective rate on private property gains (30% on 22/30 of the gain).
• Väsentlig anknytning risk: a retained Swedish home, especially a year-round house rather than a summer cottage, is a classic "essential ties" factor. For a clean break, sell or long-let the Swedish principal home and keep only fritidshus with clearly recreational use.

Swedish Pensions & Social Security

Your Swedish pension rights survive the move. EU Regulation 883/2004 on social security coordination protects you.

Statutory old-age pension

• The Swedish Pensions Agency (Pensionsmyndigheten) pays your inkomstpension, premiepension and garantipension into a bank account across the EU, including Bulgaria. Years worked in Sweden count toward your entitlement regardless of your later residence.
• Under the SE-BG treaty, private pensions (including statutory old-age for employees and self-employed) are generally taxable in the state of residence - Bulgaria, at 10%.
• Civil-service (government) pensions remain taxable in Sweden.
• Request payment abroad via Pensionsmyndigheten's Bosatt utomlands form; IBAN and SWIFT of your Bulgarian EUR account are enough.

Occupational and private pensions

Occupational pensions (tjänstepension - ITP, SAF-LO, KAP-KL) accumulated in Swedish employer plans are portable in payout but generally cannot be transferred out of the Swedish pension system. The treatment of lump-sum versus annuity payouts depends on the plan and your age at the time of drawing. Private pensions (IPS) historically deductible were closed for new contributions in 2016. For large accrued capital, coordinate with a Swedish pension adviser before triggering distribution from Bulgaria - the timing affects both Swedish and Bulgarian tax.

Timeline: From Decision to Operating

A realistic Sweden-to-Bulgaria relocation, assuming no complications:

1. Month -3 to -2 (pre-departure planning): engage a Swedish skatterådgivare to model the ten-year rule exposure and the 3:12 rules on any fåmansföretag shares. Get written opinion on väsentlig anknytning factors. Decide whether to sell Swedish company shares before or after departure.
2. Month -2 to -1: register a Bulgarian EOOD remotely or on a scouting trip. Minimum capital EUR 1. Open a corporate bank account or start the process. Line up Bulgarian address (rental or service address).
3. Month -1: notify Försäkringskassan, your a-kassa if applicable, and your pension providers. Plan ISK/KF conversion. Prepare SKV 7665.
4. Departure week: file SKV 7665 with Skatteverket at least one week before the move. Keep confirmation.
5. Week 1 in Bulgaria: register rental contract, submit EU residence application at Migration Directorate, obtain LNCH.
6. Week 2-4: register with NRA as Bulgarian tax resident; finalise NHIF coverage through EOOD contributions; activate Bulgarian bank cards.
7. Month 2-3: first payroll/dividends through Bulgarian EOOD; Bulgarian accountant starts monthly filings; VAT registration if turnover warrants.
8. Following year: file final Swedish return covering the period of Swedish residence; file first full Bulgarian annual return; obtain NRA tax residency certificate for treaty purposes.

Common Mistakes Swedish Relocators Make

1. Underestimating väsentlig anknytning

Some Swedes leave their family "temporarily" in Sweden or keep the Swedish villa as a "rental". Skatteverket can argue you never truly left for up to five years. Your Bulgarian residency will be challenged under the treaty tie-breaker, and you risk paying Swedish top rates on your worldwide income during the disputed period. Move the family, sell or long-let the principal home, close the a-kassa, simplify the Swedish business holdings.

2. Selling fåmansföretag shares too soon

Under the ten-year rule combined with the 3:12 regime and the SE-BG treaty, selling a Swedish owner-managed company in the first years after emigration is the single biggest trap. The treaty caps protect some gains but not all. Get a written Swedish opinion on your specific company, asset mix, and buyer before signing any share purchase agreement.

3. Forgetting to close or convert ISK/KF

Leaving an ISK open after emigration can trigger automatic closure by the broker, forced disposal of holdings at inconvenient prices, and lingering Swedish standard-income tax for the year of departure. Plan the conversion or transfer before SKV 7665 is filed, not after.

4. Assuming the ten-year rule always applies at 30%

Under the SE-BG treaty and the MLI, Sweden's reach is narrower than the domestic ten-year rule text suggests. Many post-emigration gains are allocated to Bulgaria under the treaty and taxed at 10% (or 0% on EU-listed shares). Do not overpay - but do not assume automatic relief either. Get the opinion.

5. Registering at a police station in Bulgaria

Outdated guides still refer to "local police registration" or "GRAO" for EU citizens. This is incorrect. The Migration Directorate is the only authority. Going to the wrong office wastes days. See our address registration guide for foreigners and the detailed EU residence permit walkthrough.

6. Not spending 183 days in Bulgaria in year one

If you move in October, the calendar-year Bulgarian day count is mathematically insufficient to claim tax residency for that year - unless you can prove centre of vital interests, which is difficult for newcomers. For a clean treaty-compliant break, plan your move for January to March.
