The Anatomy of a Bulgarian Tax Audit

Tax audits by the National Revenue Agency (NRA) are becoming more frequent, more data‑driven, and more detail‑oriented. Many businesses ask:

How do I know my accounting is compliant? What documents will auditors request? How can I avoid penalties?

This description also emphasizes problem‑solving:

What happens if the NRA finds discrepancies? How do you defend your position? What documents prove compliance?, Financial accounting – Accounting Services in Bulgaria

Step 1: The Audit Assignment Order (ZVR)

An audit begins officially when the NRA serves an Audit Assignment Order (Заповед за възлагане на ревизия). This document explicitly states:

• The audited entity and registration details.
• The assigned revenue inspectors and audit lead.
• The exact scope (e.g., Corporate Income Tax, VAT, Social Security Contributions).
• The audited tax period (the NRA can audit back up to 5 calendar years from the deadline of the relevant return).
• The designated timeframe for completion (typically 3 months, extendable by up to 2 months, or longer in complex cross-border cases).

Step 2: The Audit Phase & Information Requests

Inspectors request primary accounting documents, electronic sales ledgers, contracts, bank statements, and written explanations. Submissions are primarily handled digitally through the NRA E-Services Portal using a Qualified Electronic Signature (QES).

Step 3: The Audit Report (Ревизионен доклад – RD)

Within 14 days after the audit phase ends, the NRA issues an Audit Report detailing their factual findings, calculated adjustments, and proposed liabilities.

Step 4: Your Defense Window (Objections)

You have 14 calendar days from the receipt of the Audit Report to submit a formal written objection (Възражение). You may request a 1-month extension if additional supporting evidence needs to be gathered.

Step 5: The Audit Act (Ревизионен акт – RA)

Within 14 days of the objection deadline, the NRA issues the final Audit Act. This document sets the final tax liability, interest charges, and deadlines for payment, Taxes – Accounting Services in Bulgaria

How to Survive: Pre-Audit Preparation Checklist

Surviving an audit starts long before the NRA issues a ZVR. Follow these essential compliance practices:

1. Master Statutory Document Retention

Bulgarian accounting law establishes clear mandatory archiving periods:

• 5 Years: Tax returns, VAT purchase/sales ledgers, supporting returns.
• 10 Years: Primary accounting documents (invoices, bank receipts, contracts, protocols).
• 50 Years: Payroll ledgers and employment agreements.

2. Verify Primary Supporting Documents

A tax-deductible expense in Bulgaria requires more than just an invoice. Inspectors scrutinize whether transactions actually took place (economic reality vs. formal paperwork):

• Attach signed Acceptance Protocols (Приемо-предавателни протоколи) or delivery notes for services and goods.
• Document the commercial rationale for consultancy, management, or marketing fees.
• Ensure supplier VAT numbers are valid in the EU VIES or NRA database at the time of the transaction.

3. Maintain Digital Alignment

Ensure your electronic accounting data aligns with NRA filings (VAT returns, SAF-T/e-invoicing standards, and cash-register telemetry). Discrepancies between monthly VAT logs and annual financial statements are automated triggers for audits.

Play Defense with Pristine Bookkeeping

When the official audit notice arrives, your response time and organization dictate the tone of the review.

• Keep Documents Audit-Ready: Maintain chronological, unbroken sequences of invoices, protocols, bank slips, and payroll sheets.
• Document Business Purpose: Every expense must clearly serve the economic interest of the company. If an expense cannot be justified with a tangible contract, delivery protocol, or report, treat it as non-deductible beforehand.
• Clarity from your Accountant: Your internal or outsourced accounting team must be able to explain basic revenue, margin movements, and balance adjustments without delay or confusion, Annual closing – Accounting Services in Bulgaria

How to THRIVE: Strategic Audit Defense

To minimize penalties and protect your business rights, adopt a structured defense posture during an active audit:

Contesting an Adverse Audit Act

If the NRA issues an Audit Act claiming back taxes or penalties, you have two levels of protection:

Administrative Appeal (Mandatory Step 1):

• Must be filed within 14 days of receiving the Audit Act.
• Submitted to the Director of the Directorate for Appeals and Tax and Social Security Practice (ODOP / ОДОП) via your local NRA territorial directorate.

Judicial Appeal (Step 2):

• If ODOP rejects the appeal or fails to rule on time, you can appeal to the regional Administrative Court within 14 days.

NEXT, important: Instead of viewing the inspector as an adversary, treat the audit as an independent health check of your corporate structure,

• Professional Representation: Have your certified accountant or a specialized tax professional manage direct communications and document handovers with the NRA.
• Correct Early, Correct Fast: If an internal review uncovers a minor reporting error before the audit concludes, active cooperation and voluntary adjustments significantly minimize administrative friction.
• Post-Audit Implementation: Use the auditor’s final feedback report to patch systemic weak points in your workflow, making your next fiscal year bulletproof, ABOUT US | Accounting Services in Bulgaria

Crucial Tip on Staying Enforcement: Appealing an Audit Act does not automatically freeze tax collection. To suspend immediate execution, you must lodge collateral (cash deposit, unconditional bank guarantee, or approved financial securities) equal to the principal plus accrued interest, How we work – Accounting Services in Bulgaria
