The Most Common Tax Mistakes Bulgarian Companies Make (and How to Avoid Them)

By Published On: 20/04/2026Актуализирана: 04/05/2026

Bulgaria is often seen as one of the most attractive tax jurisdictions in Europe. With:

  • a flat 10% corporate tax
  • relatively straightforward rules
  • EU membership

…it is an appealing destination for both local entrepreneurs and international businesses. However, despite this favorable environment, many companies make the same tax mistakes – often leading to:

  • financial corrections
  • audits
  • penalties

In most cases, these issues don’t arise from intentional wrongdoing, but from:

  • misunderstanding the rules
  • poor advice
  • fast decisions in a dynamic business environment

Below are the most common tax mistakes — and how to avoid them.

1. Incorrect VAT Treatment

VAT is one of the most frequent sources of issues during tax audits.

Many companies assume: if they receive and pay an invoice with VAT, they can automatically reclaim it. In reality, the rules are more complex.

To reclaim VAT:

  • the transaction must be real
  • it must be related to business activity
  • there must be sufficient supporting evidence

An invoice alone is often not enough. During an audit, authorities may require:

  • contracts
  • acceptance protocols
  • correspondence
  • proof of delivery or performance

A common mistake is reclaiming VAT on expenses that are actually personal or unrelated to the business.

How to avoid it: Ensure every transaction is real, business-related, and well documented.

2. Expenses Without Proper Documentation

In fast-moving businesses, documentation is often overlooked. This creates significant tax risk.

Every expense must be:

  • properly documented
  • economically justified
  • clearly connected to the business

If documentation is incomplete or unclear, the expense may be rejected for tax purposes. mThis can result in:

  • higher taxable profit
  • additional tax liabilities
  • potential audits

How to avoid it: Maintain full documentation — invoices, contracts, and proof of execution.

3. Personal Expenses Paid by the Company

This is especially common in smaller businesses. Typical examples include:

  • daily personal purchases
  • travel unrelated to business
  • household expenses
  • personal equipment
  • restaurants without business purpose

While convenient, this practice is risky. If an expense is not business-related:

  • it cannot be recognized for tax purposes
  • it may be treated as hidden profit distribution

This can lead to:

  • additional corporate tax
  • dividend tax
  • penalties and interest

How to avoid it: Keep a clear separation between personal and business finances.

4. Transfer Pricing Issues Between Related Parties

With international expansion and group structures, this becomes increasingly important. Transactions between related companies must be conducted at market (arm’s length) prices. If not, tax authorities may assume that profits are being shifted artificially.

This can result in:

  • profit adjustments
  • additional tax liabilities
  • penalties

Many entrepreneurs underestimate this risk, especially when working with their own companies in different jurisdictions.

How to avoid it: Ensure all related-party transactions are at market terms and properly documented.

5. Incorrect Dividend Distribution

Distributing profits may seem straightforward – but mistakes are common.

Key rules:

  • dividends can only be distributed from actual profits
  • dividend tax must be declared and paid on time
  • international structures may trigger additional tax considerations

Failure to comply can lead to:

  • penalties
  • interest
  • tax adjustments

How to avoid it: Follow legal procedures carefully and consider cross-border tax implications.

6. Missing or Late VAT Registration

Many companies underestimate when VAT registration becomes mandatory — especially when:

  • growing quickly
  • working with international clients

Common issues:

  • missing the turnover threshold (~EUR 51,000)
  • ignoring early VAT triggers (EU services, etc.)

Late registration can result in:

  • retroactive VAT liabilities
  • penalties
  • no right to reclaim VAT for past periods

How to avoid it: Monitor turnover regularly and analyze all transactions — especially cross-border ones.

7. Incorrect Treatment of International Services

As businesses become more global, VAT rules become more complex.

Common mistakes include:

  • incorrect place of supply
  • failing to apply reverse charge
  • misreporting cross-border transactions

This can lead to:

  • double taxation
  • missing VAT where required
  • audit risks

How to avoid it: Clearly determine VAT treatment for each international transaction.

8. Incorrect Treatment of Employee Benefits

Expenses related to employees are often misunderstood:

  • bonuses
  • vouchers
  • travel
  • accommodation
  • additional benefits

Not all of these are automatically tax-deductible.

Some may:

  • be treated as personal income
  • require social contributions

Incorrect treatment can lead to:

  • additional taxes
  • penalties

How to avoid it: Review the tax treatment of each benefit and document it properly.

9. Lack of Tax Strategy During Growth

As companies grow, many continue operating with structures that were suitable only at an early stage.

This leads to:

  • inefficient tax positioning
  • increased risks
  • problems during audits or investor due diligence

Often, these issues are only discovered:

  • during tax inspections
  • when raising investment
  • when expanding internationally

How to avoid it: Review your business structure regularly — especially during growth or expansion.

How Companies Can Reduce Risk

Most tax problems arise not from intent, but from lack of clarity. A few practical principles can significantly reduce risk:

  • maintain strong documentation for key transactions
  • separate personal and business finances
  • seek advice before making decisions
  • review your tax strategy regularly
  • work with experienced professionals

Build Structure – Not Just Compliance

Tax environments are becoming more dynamic, and control is increasingly digital. The right approach is not just to meet minimum requirements. It is to build a robust financial and tax structure.

This helps businesses:

  • reduce risk
  • improve transparency
  • create a solid foundation for growth
