Tax & Compliance

Tax Law in Bulgaria

Bulgaria's flat 10% personal and corporate tax rates are among the lowest in the EU - but the practical reality of staying compliant is more involved than the headline rate suggests. We advise residents, foreign nationals, companies and crypto holders on every layer of the Bulgarian tax system: residency planning, ongoing compliance, cross-border structuring, and defence against NAP audits and assessments.

Who we work with

  • Foreign nationals relocating to Bulgaria for tax-residency benefits
  • Bulgarian residents with foreign income or assets
  • Founders, freelancers and digital nomads
  • Bulgarian and international companies of all sizes
  • Crypto traders, miners and Web3 founders
  • Property owners and rental landlords
  • Heirs and donors managing inheritance or gifts

Personal income tax & residency planning

  • Tax-residency assessment (183-day rule, centre-of-vital-interests test, permanent-address qualification and treaty tie-breakers)
  • Annual income declarations and supporting documentation
  • Relocation planning for foreign nationals - including the residence-permit / tax-residency interaction
  • Treatment of foreign-source income, dividends, capital gains and stock options
  • Self-employment, freelance and patent-tax (patent-based) regimes - including the applicable social-security base

Corporate income tax & ongoing compliance

  • Annual corporate income tax (flat 10%) returns filed 1 March - 30 June with tax due by 30 June
  • Withholding tax planning - including the 5% dividend tax for individuals, Parent–Subsidiary Directive eligibility and treaty reductions
  • Tax depreciation, loss carry-forward and group structuring
  • Transfer pricing documentation for related-party transactions
  • Tax-efficient structures for IP, software, crypto and royalty flows

VAT registration & compliance

  • Mandatory VAT registration under Article 96 ZDDS - generally upon annual domestic turnover exceeding EUR 51,130, subject to separate registration grounds and special regimes
  • Voluntary registration analysis (for B2B exporters and EU traders)
  • Place-of-supply, reverse-charge and intra-Community supply rules - three distinct concepts frequently conflated
  • OSS for certain cross-border B2C services and distance sales; IOSS for qualifying distance sales of imported goods
  • VAT refunds, offsetting and recovery disputes
  • Standard 20% rate vs. the reduced 9% rate (applies only to expressly enumerated supplies)

Crypto & digital-asset taxation

  • Classification of crypto activity - investment vs. business / professional trading
  • Annual calculation under Article 33 PIT Act for individual disposals of virtual currencies - aggregate gains offset against aggregate losses, statutory expense deduction, then 10% rate
  • Treatment of staking, lending, airdrops, mining and DeFi yield
  • Token and digital-asset characterisation where they fall outside the Article 33 "virtual currency" definition
  • Crypto-to-fiat off-ramping and the source-of-funds story for banks
  • Coordination with crypto regulatory advice and AML/KYC obligations

Cross-border & treaty work

  • Application of Bulgaria's ~70 double-taxation treaties (DTAAs)
  • Avoidance of double taxation on foreign salary, dividends and royalties
  • CRS / DAC2 disclosures and the practical effect on Bulgarian residents abroad
  • Permanent establishment (PE) risk for foreign companies operating into Bulgaria
  • Beneficial-ownership documentation and treaty-benefit certificates

Property, inheritance & gift tax

  • Annual real-estate tax and waste-collection fee (set by each municipality)
  • Municipal acquisition tax on transfers for consideration - rate set by the relevant municipality within the statutory range; the acquirer is generally liable unless the parties agree otherwise (Art. 45 ZMDT)
  • Rental-income declarations for landlords
  • Inheritance tax - rates and exemptions for direct vs. lateral heirs (set at the municipal level within statutory limits)
  • Gift-tax rates, exemptions and planning between family members

Tax audits, disputes & refunds

  • Representation in NAP (National Revenue Agency) audits and inspections
  • Administrative appeal of revisional acts (РА) under the Tax-Insurance Procedure Code - filed through the issuing authority to the competent director of the Appeals and Tax-Insurance Practice Directorate within 14 days
  • Suspension of enforcement during appeal - an appeal does not automatically suspend a revision act; a separate application supported by existing or proposed statutory security is generally required (Art. 153 DOPK)
  • Judicial appeals before the competent Administrative Court and the Supreme Administrative Court (VAS)
  • VAT refund, offsetting and recovery disputes - including unlawful delay or refusal
  • Evidentiary agreements during administrative appeal where legally available, and statutory applications for deferral or instalment payment of public liabilities

Why early advice matters

The Bulgarian tax system rewards planning. Tax residency, company structure, the right VAT regime, and the right characterisation of crypto or foreign income are generally addressed most effectively before the relevant transaction or tax period is completed. Once a NAP audit has started, the available options usually narrow - at that point the work shifts from structuring to evidentiary and procedural defence.
