Montenegro Cross-Border Tax Guide 2026

Overview — Cross-Border Taxation in Montenegro

Montenegro's cross-border tax rules are governed by the Law on Corporate Income Tax, the Law on Personal Income Tax, and the Law on Tax Administration. The Tax Administration has been strengthening its international tax capacity, including participation in the OECD's Base Erosion and Profit Shifting (BEPS) Inclusive Framework. As an EU candidate country, Montenegro is progressively aligning its tax legislation with EU standards and directives. Multinational enterprises operating in Montenegro must comply with transfer pricing documentation requirements, thin capitalisation rules, and withholding tax obligations. Non-residents earning Montenegro-source income are generally subject to withholding taxes at statutory rates, which may be reduced under applicable treaties.

Transfer Pricing — OECD Guidelines

Montenegro's transfer pricing rules follow the OECD Transfer Pricing Guidelines. The regulations require that transactions between related parties be priced at arm's length. Related parties include companies under common control, parent-subsidiary relationships, and individuals with significant influence. Documentation requirements include a master file and local file for qualifying taxpayers. Acceptable transfer pricing methods include the Comparable Uncontrolled Price (CUP) method, Cost Plus method, Resale Price method, Transactional Net Margin Method (TNMM), and Profit Split method. Advance Pricing Agreements (APAs) are available for qualifying taxpayers. Penalties for non-compliance may include tax adjustments and interest.

Thin Capitalisation Rules

Montenegro's thin capitalisation rules limit the amount of interest that a company can deduct on related-party debt. The maximum allowable debt-to-equity ratio is 4:1 (debt exceeding equity by no more than 4 times). Interest on debt exceeding this ratio is disallowed as a deduction. The rules apply to all related-party debt, including loans from foreign parent companies and sister companies. Certain long-term financing from approved financial institutions may be exempt. The Tax Administration may also apply general anti-avoidance rules where debt arrangements lack commercial substance. Interest on loans from non-residents is subject to withholding tax at 9% (reduced under DTTs).

Withholding Taxes to Non-Residents

Payments to non-residents from Montenegro-source income are subject to withholding tax at the following standard rates (treaty rates may apply):

• Dividends — 15% (reduced to 5-10% under most DTTs)
• Interest — 9% (reduced to 5-10% under DTTs)
• Royalties — 15% (reduced to 5-10% under DTTs)
• Management, consulting, and technical fees — 9%
• Rental of movable property — 9%
• Capital gains on real estate — 15%

The person making the payment must withhold the tax and remit it to the Tax Administration. A withholding tax certificate must be issued to the non-resident. Treaty relief requires the non-resident to provide a Certificate of Tax Residency.

Controlled Foreign Company (CFC) Rules

Montenegro's CFC rules attribute certain passive income of a foreign company to its Montenegrin resident shareholders where the foreign company is controlled by Montenegrin residents. A foreign company is a CFC if Montenegrin residents hold more than 50% of the shares, voting rights, or entitlements to profits. The attributed income includes dividends, interest, royalties, rent, and capital gains of the CFC. The rules are designed to prevent Montenegrin residents from deferring tax by earning passive income through foreign entities in low-tax jurisdictions. Active business income of the CFC is not attributed.

Double Tax Treaties — Practical Application

Montenegro has over 40 double tax treaties. To claim treaty benefits, a non-resident must:

• Obtain a Certificate of Tax Residency from the home country tax authority
• Submit a treaty relief application to the Montenegrin Tax Administration
• Provide the certificate to the Montenegrin withholding agent
• Wait for approval (typically 2-4 weeks)

Treaty benefits include reduced withholding tax rates and potential exemption from CGT on certain assets. Montenegro's treaties generally follow the OECD Model Convention. The Limitation on Benefits (LOB) clauses in newer treaties restrict treaty access to genuine residents.

FAQs

Do I need to register for tax in Montenegro as a non-resident investor?

Non-residents earning Montenegro-source income (e.g., dividends, interest, rent) generally do not need to register if the income is subject to final withholding tax. However, a non-resident with a permanent establishment in Montenegro must register and file tax returns.

How do I claim a refund of excess WHT?

A non-resident may claim a refund if WHT was deducted at the full statutory rate when a reduced treaty rate should have applied. The refund claim is submitted to the Tax Administration with supporting documents.

Does Montenegro have a General Anti-Avoidance Rule (GAAR)?

Yes, Montenegro's tax legislation includes a GAAR that allows the Tax Administration to recharacterise transactions entered into primarily for tax avoidance purposes.
