Tax law attorneys for corporate clients in Sofia

Tax law attorneys for corporate clients in Sofia

​

You run a mid-sized logistics company based in Sofia with satellite offices in Kostinbrod and Elin Pelin. During a routine review, the National Revenue Agency initiates a tax audit that stretches over several months. Suddenly, you're notified of an unexpected VAT adjustment, penalties for alleged undeclared income, and a potential reassessment of your corporate tax liabilities.

​

This is a common scenario we often encounter, especially among growing companies operating across Sofia and the nearby regions of Botevgrad, Samokov, and Bozhurishte. Many business owners come to us asking:

​

• How can we challenge a tax assessment that seems unreasonable?
• What are the legal risks during a tax audit?
• How do we plan for long-term compliance without overpaying?

​

Understanding how corporate tax law works in Bulgaria — and being represented by experienced tax solicitors — is key to protecting your business and staying compliant.

​

Can we challenge an unfair tax audit or reassessment by the Bulgarian tax authorities?

​

Yes, under Bulgarian law, every tax assessment decision issued by the National Revenue Agency (NRA) can be appealed. Clients often face this when an audit ends with a report proposing additional VAT or corporate tax liabilities, often coupled with penalties.

​

According to Article 117 of the Bulgarian Tax and Social Insurance Procedure Code (TSIPC):

​

“Each act issued by the revenue authority which affects the rights or obligations of taxable persons may be appealed before the higher administrative authority and the respective administrative court.”

​

In practical terms, this means that if your company receives a revised tax notice suggesting underpayment, you are entitled to challenge both the substantive findings and the penalties. Appeals can be administrative (within the NRA hierarchy) or judicial (before the Administrative Courts).

​

We routinely assist clients in Sofia, Slivnitsa, and Dragoman with:

​

• Filing timely objections against tax audit reports
• Gathering counter-evidence (e.g., accounting records, invoices, contracts)
• Representing clients before the administrative court during tax penalty appeals in Sofia and beyond

​

Appeals must be filed within 14 days of receiving the assessment. Missing this deadline can make the liabilities final, so prompt legal assistance is critical.

​

What are the risks of a tax audit and how should we prepare?

​

Tax audits in Bulgaria are formal procedures regulated under Chapter Eighteen of the TSIPC. They can focus on general corporate tax compliance or specifically investigate undeclared income or suspicious transactions.

​

According to Article 119 of the TSIPC:

​

“The revenue authority shall notify the taxable person in writing about the initiation of the tax audit, except where this could prejudice the audit.”

​

This means that, in most cases, you will be informed and allowed to respond. However, in certain investigations — particularly in cases involving alleged tax fraud or undeclared income — the authorities may proceed without prior notice.

​

We help companies in Lozen, Dolna Banya, and Svoge prepare for tax audits by:

​

• Conducting pre-audit reviews of accounting systems and tax filings
• Identifying risks related to VAT registration and disputes
• Preparing employees and management for audit interviews
• Ensuring proper documentation of all business transactions

​

Common risks during a tax audit include:

​

• Re-assessment of tax owed, with interest and penalties
• Accusations of tax fraud, especially where cash payments or offshore transactions are involved
• Freezing of assets or accounts during the investigation

​

Having a tax fraud defense lawyer in Sofia during the audit phase can make a crucial difference. In many cases, we have managed to close audits with reduced or no liabilities.

​

What are our corporate tax obligations and how can we ensure compliance?

​

In Bulgaria, profits made by legal entities are taxed under the Corporate Income Tax Act (CITA). The standard corporate tax rate is currently 10%. Compliance includes timely filing of tax returns, keeping accurate accounting records, and applying the correct treatment to income, expenses, and VAT.

​

According to Article 92(1) of the CITA:

​

“Taxable persons shall submit an annual corporate tax return under Article 93 for the previous year no later than 31 March of the following year.”

​

That means if your company operates in Ihtiman, Pravets, Bankya or any other part of Sofia District, you must file your corporate tax return by March 31 each year and pay any tax due.

​

Our services in corporate tax compliance in Bulgaria include:

​

• Preparation and review of annual tax returns
• Verification of tax-deductible expenses and depreciation schedules
• Monitoring of VAT compliance, especially in sectors like construction, logistics, and IT
• Registration and administration of group companies for cross-border tax planning

​

We currently support several international corporate groups operating across Godech, Kostenets, and Sofia — ensuring both Bulgarian compliance and coordination with parent companies abroad.

​

We’ve discovered undeclared income from previous years. What are our legal options?

​

This is a sensitive but not uncommon issue. Often, new management or external accountants uncover undeclared income from prior reporting periods — perhaps freelance payments, cash invoices, or incorrect partner transactions.

​

Under Article 103 of the TSIPC:

​

“Persons who discover inaccuracies in submitted tax returns may make corrections by submitting a corrective return, unless a tax audit has already started.”

​

This clause gives you the opportunity to voluntarily declare previously unreported income before an audit is opened, which often results in:

​

• Lower penalties
• Avoidance of criminal investigation
• A better standing with the tax authority in future interactions

​

We have assisted clients in Botevgrad, Elin Pelin, and Bozhurishte in resolving such situations by:

​

• Conducting internal tax reviews to identify exposure
• Submitting voluntary corrections and negotiating payment plans
• Preparing legal responses in cases of audit or enforcement

​

In some cases, full representation before the tax authorities is also necessary if the NRA challenges the corrections.

How should we declare cryptocurrency income to avoid penalties in Bulgaria?

​

A client based in Samokov approached us after receiving a formal inquiry from the National Revenue Agency (NRA) regarding unreported gains from crypto trading over the past two tax years. The client had been using offshore exchanges and was uncertain whether capital gains from those sales were subject to Bulgarian taxation. He had not included the income in his tax return, assuming digital assets were outside the scope of local tax rules.

​

Under the Bulgarian Personal Income Tax Act (PITA), all individuals and entities are required to declare their worldwide income, including gains from the disposal of virtual currencies. Article 33(3) of the PITA specifically includes profits from the sale or exchange of financial assets, which the NRA interprets to include cryptocurrency assets. Failure to declare such income may lead to audits, penalties, and interest charges — and in serious cases, allegations of tax evasion.

​

We assist clients with cryptocurrency tax compliance by first determining whether the income is taxable under Bulgarian law. We prepare amended income tax returns where appropriate and submit voluntary disclosures in cases where the client has not yet been audited. Our experience shows that self-correction before formal proceedings significantly reduces the risk of penalties. For clients in Samokov, Botevgrad, and Lozen engaged in frequent crypto trades or mining activity, we often provide annual tax reviews and ongoing legal guidance.

​

Can we optimise tax treatment of international staff and contractors?

​

One manufacturing company operating in Elin Pelin asked us to assist with a group of non-resident consultants based in Germany and Austria. The issue involved whether payments to these individuals triggered a withholding tax obligation under Bulgarian law, and whether the company's internal structure exposed it to avoidable double taxation risks. Payroll had inconsistencies in how remuneration to foreign nationals was being reported to the Bulgarian authorities.

​

Under Article 195 of the Bulgarian Corporate Income Tax Act (CITA), Bulgarian payers of income to foreign legal entities without a permanent establishment in Bulgaria must withhold tax at the source, unless an applicable double taxation agreement (DTA) provides for tax exemption or a reduced rate. For example, Bulgaria's DTAs with Germany and Austria require specific forms and documentation to apply reduced rates. If incorrectly withheld, the company could either face liability or complicate the foreign contractors’ tax credits abroad.

​

We address this by analysing applicable DTAs and advising on both tax residency determination and the qualification of foreign service providers under Bulgarian tax regulations. In these cases, we structured contractor agreements to align with treaty rules and filed the required DTA relief declarations. We often assist businesses in Elin Pelin, Bankya, and Slivnitsa with ongoing international tax advice regarding foreign staff, including the setup of compliant reporting systems and mitigation of double withholding exposure.

​

What should we do if foreign tax authorities challenge our Bulgarian tax residence?

​

A senior executive with dual residence in Sofia and Paris contacted us after receiving a tax audit notice from the French tax authorities. France was claiming her worldwide income, including income declared and taxed in Bulgaria, on the basis that her “centre of vital interests” was located in France. The client had already filed her income tax returns in Bulgaria as a tax resident, and now risked being taxed a second time.

​

This kind of conflict revolves around the tax residency determination rules embedded within bilateral DTAs. Article 4(2) of most tax treaties signed by Bulgaria, including the Bulgarian-French DTA, outlines tie-breaker rules for individuals who qualify as resident in both contracting states. These include criteria such as permanent home, habitual abode, and where the person's vital interests lie. Errors or omissions in residence declarations can lead to retroactive penalties and double taxation unless resolved.

​

We regularly advise clients in Sofia, Kostenets and Godech on resolving residency disputes through mutual agreement procedures (MAP), supported by Article 24 of the respective DTA. We prepare detailed residency claims substantiated by documentary evidence (leases, utility bills, bank statements, schools, etc.) and liaise with Bulgarian and foreign tax authorities to secure a binding resolution. Our tax lawyers ensure that future declarations accurately reflect the taxpayer’s central economic and social interests to prevent recurring disputes.
