10 Essential Questions About TIN in Montenegro

In Montenegro, the Tax Identification Number is called the PIB (Poreski identifikacioni broj).

It is a unique identifier assigned to legal entities and individuals for all tax purposes. It effectively acts as both a tax ID and a VAT number (when registered for VAT).

Montenegro distinguishes clearly between corporate entities and natural persons:

• Business PIB: The primary tax ID for companies (DOO, AD).

• Individual JMBG: The Unique Master Citizen Number (Jedinstveni matični broj građana). This 13-digit number is the standard identification for citizens across former Yugoslav countries.

• CRPS Registration Number: The registration ID issued by the business court, though the PIB is often used as the primary key.

The formats are strictly numeric and follow distinct generation rules.

• Business PIB: A strictly 8-digit numeric string.

  • Structure: It is randomly generated but always concludes with a specific checksum algorithm (Modulo 11).

• Individual JMBG: A 13-digit string.

  • Structure: Encodes the date of birth (DDMMYYY), region of birth, gender, and control digits.

• CRPS Number: Typically corresponds to the registration sequence in the central court database.

Technical Note: When processing onboarding data, a common error is confusing the PIB (8 digits) with the JMBG (13 digits). While an individual entrepreneur might provide their JMBG, corporate invoicing requires the PIB. TaxDo’s Global Syntax Verification (GSV) automatically distinguishes these two formats to prevent validation failures in the EFI system.

The Revenue and Customs Administration (UPC) issues the PIB. The Central Register of Business Entities (CRPS) handles corporate registration. The Ministry of Interior (MUP) issues the JMBG (National ID).

• Local Businesses: Mandatory for any economic activity.

  • VAT Threshold & Rates: The standard rate is 21%. However, a 7% reduced rate applies to essentials, and a new 15% intermediate rate (introduced in 2026 reforms) applies to specific sectors like hospitality and food services.

• Non-Resident Digital Services: Foreign companies providing electronic services to Montenegrin consumers must register for VAT and obtain a PIB.

• Real Estate Investors: Foreigners purchasing property must obtain a PIB to pay property transfer tax.

The registration process in Montenegro is centralized but involves distinct steps for Legal Existence vs. Tax Compliance.

Step 1: Company Registration (CRPS)

• Portal: Visit the Central Registry of Commercial Entities (CRPS) website.

• Action: Submit the Registration Form (JPR) along with Articles of Incorporation and proof of bank capital deposit (min €1 for LLCs).

• Outcome: Within 5-7 days, you receive the Certificate of Registration. Crucially, the PIB (8-digit Tax ID) is printed on this certificate. You do not need to apply for a PIB separately; it is assigned at the birth of the company.

Step 2: General Tax Registration (UPC)

• Portal: Go to the Revenue and Customs Administration (UPC) website to download the JPR Form.

• Action: Within 24 hours of receiving your PIB, you must file the JPR form with the local tax office to activate the PIB in the tax database.

• Outcome: Your company is now visible in the central tax system.

Step 3: VAT (PDV) Registration

• Action: If your expected turnover exceeds €30,000, you must submit the PR-PDV-1 Form to the UPC.

• Outcome: You receive a VAT Certificate (Potvrda o registraciji za PDV). Your PIB is now flagged as "Active" for VAT purposes.

Step 4: Electronic Fiscalization (SEP)

• Requirement: Before issuing your first invoice, you must obtain a Digital Certificate (from Posta Crne Gore or CoreIT).

• Action: Log in to the SEP Self-Care Portal (Efiskalizacija), register your business unit, and link your operator software.

• Outcome: You obtain security codes allowing you to issue fiscalized invoices (JIKR).

Verification is essential because only an "Active" PIB can receive a valid fiscal invoice.

• The Manual Way:

  • CRPS Search: The Central Registry allows searching for companies by name or registration number to see their legal status (Active, Deleted, Bankruptcy).

  • EFI Portal: Checks if a taxpayer is fiscalized.

• The Scalability Gap: The CRPS site requires manual input, often has downtime, and relies on CAPTCHA. This makes it impossible to automate checks for a high volume of users. Solve this with TaxDo’s Tax ID Validator to bypass manual hurdles.

• The Solution: We connect directly to the registry logic to validate the ID in real-time.

TaxDo delivers a regulatory-grade Global TIN Validation platform, essential for the Euro-based Montenegrin market.

• Official Global TIN Lookup (125+ Countries): Real-time validation via UPC/CRPS logic to confirm if the Business PIB is active.

• Fiscalization Readiness: Ensures the PIB you are invoicing is valid, preventing rejection errors from the EFI server.

• Identity Distinction: Separates JMBG (Personal) from PIB (Business), ensuring accurate tax reporting.

• Enterprise-Ready: Features automated revalidation and bank-grade security.

We cover the complete spectrum of Montenegrin identifiers required for compliant onboarding:

A valid PIB is the key to the mandatory "Fiscal Service". Here is how it is used:

The penalties for non-compliance are strict under the Law on Fiscalization:

• Invoice Rejection: If the buyer's PIB is invalid, the EFI system will not generate the IKOF (fiscal verification code), rendering the invoice illegal.

• Fines: Penalties for failing to issue a fiscalized invoice can range from €650 to €20,000.

• Business Closure: Repeated offenses can lead to a temporary ban on business operations (up to 90 days).
