Legal support with tax assessments in Sliven
You run a family business in Sliven and recently received a tax assessment from the local office of the National Revenue Agency (NRA). The auditors claim you underreported your revenue and are now seeking penalties and back taxes. You’ve kept diligent records and believe their conclusions are flawed — but you're unsure how to respond or what legal recourse is available.
Many of our clients throughout Sliven, Nova Zagora, Tvurditsa, Kotel, and Shivachevo find themselves in similar situations. Whether facing a routine audit or a more serious tax investigation, the process can be intimidating, especially for those unfamiliar with the local procedures or language. Questions we hear often include:
- “How can I challenge a tax assessment?”
- “What are my rights during a tax audit?”
- “Should I speak to a tax lawyer before responding to the NRA?”
- “Is it possible to reduce or suspend a tax penalty?”
Our team at Black Sea Law Counsel provides comprehensive legal representation in tax disputes, including advice on appealing tax assessments, corporate tax compliance in Bulgaria, and defense during tax audits and investigations.
Is it worth appealing a tax assessment if I disagree with the findings?
Yes — under Bulgarian law, you are entitled to appeal both the tax assessment and any penalties it imposes. But the timelines are short, and the process must follow strict formalities.
According to Article 154(1) of the Bulgarian Tax and Social Insurance Procedure Code (TSIPC):
“A person may appeal an act of the revenue authorities before the director of the competent territorial directorate of the National Revenue Agency within 14 days of its service.”
This means you have just two weeks after receiving the notice to act. Failing to file a timely objection may result in the assessment becoming final — even if it was flawed. Once the objection is filed, the tax authority must review the facts again internally, and may uphold, amend, or revoke its earlier decision.
In our practice across Sliven and its surrounding municipalities, we assist clients by:
- Reviewing the tax assessment for procedural or factual errors
- Preparing detailed arguments supported by accounting and legal analysis
- Representing clients in internal review procedures and before the administrative courts
- Advising on suspension of enforcement while the case is pending
A well-prepared objection can often persuade the NRA to amend or cancel the assessment, avoiding lengthy litigation.
What are my obligations and rights during a tax audit or investigation?
Tax audits and investigations are governed by strict rules under Bulgarian law — both for the tax authority and for the taxpayer. Still, many problems arise when individuals and businesses don’t know what documentation they are required to provide or how to respond when approached by auditors.
As per Article 114(1) of the TSIPC:
“The revenue authority shall carry out a tax inspection by performing actions with the purpose to establish obligations or circumstances of importance for taxation through documentary or on-site examinations.”
In practice, this means the NRA can demand access to invoices, contracts, and accounting logs. But they must also inform you of the scope of the audit, its duration, and your rights — including the right to legal representation.
We frequently support clients in Sliven and Nova Zagora during ongoing tax audits by:
- Attending all interviews and document reviews
- Ensuring the NRA respects lawful procedures and confidentiality
- Preparing responses to audit findings
- Preventing misinterpretations that might lead to penalties
When the audit extends into a formal investigation regarding suspected tax fraud or undeclared income, the stakes are even higher — and early legal intervention is essential.
Can I get legal help for undeclared income or VAT disputes?
Yes — navigating disputes over value-added tax (VAT) or alleged undeclared income requires careful strategy. These cases are common not just in Sliven, but also in more rural areas like Kotel and Shivachevo, where smaller businesses sometimes struggle with recordkeeping.
The most frequent issues we see include:
- Clients unaware of registration thresholds under the Bulgarian VAT Act
- Invoices being deemed invalid due to administrative errors
- Receiving VAT adjustment notices due to late reporting
According to Article 96(1) of the Bulgarian VAT Act:
“Any taxable person whose taxable turnover for a period not exceeding 12 consecutive months prior to the current month exceeds BGN 100,000 shall be obligated to register under this Act within 7 days after the expiry of that period.”
Failure to register on time — even by accident — can lead to retroactive VAT liabilities and fines. We provide legal support with VAT registration and disputes by:
- Reviewing whether the statutory threshold was correctly calculated
- Challenging unlawful VAT assessments
- Negotiating with the NRA to mitigate penalties
- Advising on re-registration following deactivation
Corporate clients also rely on us for continuing corporate tax compliance in Bulgaria, enabling them to avoid such problems before they arise.
What are the consequences of tax penalties, and how can I appeal them?
Penalties can include fines, default interest, and even property attachment. These sanctions are often imposed automatically after a tax assessment becomes final — but many can be appealed or mitigated.
Article 18 of the Bulgarian Tax and Social Insurance Procedure Code provides:
“The person declared as liable may submit a request for deferral or rescheduling of the public obligation in case of temporary financial difficulty.”
This legal mechanism can help clients whose businesses are facing liquidity issues, especially in seasonal industries common in the Tvurditsa region. We combine legal and financial analysis to submit compelling requests for:
- Postponement or rescheduling of tax debts
- Suspension of enforcement pending appeal
- Reduction of penalty interest
When needed, we also provide full representation before the tax authorities and the administrative courts. Whether you need a tax lawyer consultation in Sliven or a tax fraud defense lawyer in the surrounding towns, our team has the regional experience to act efficiently.
