## The Regulatory Shift in Montenegro
- On **24 July 2026**, Montenegro published a package of tax laws in “Službeni list CG 104/26” amending the **Corporate Profit Tax Act**. These amendments include harmonisation with EU law, specifically revising rules around **interest and loan deductions** and taxation for **non-resident entities**.([gov.me](https://www.gov.me/cyr/clanak/novi-poreski-zakoni?utm_source=openai))
- Also adopted were changes to the **Law on Tax Administration** aligning with EU norms on exchange of information and reporting, plus a legal foundation for establishing a **Central Liaison Office**.([gov.me](https://www.gov.me/cyr/clanak/novi-poreski-zakoni?utm_source=openai))
## Key Changes & Impacts for Businesses
| Area | What’s Changed | Implication for Businesses |
|---|---|---|
| **Loan/Interest** | Tighter specification of what interest payments may be **tax deductible**, consistent with EU anti-base erosion standards. Specified thresholds or documentation may be required. | Companies with related-party loans must revise documentation; real economic substance and rate arms-length will be scrutinised. |
| **Non-Resident Taxation** | Clarified rules for withholding and tax treatment of non-resident entities’ income activities in Montenegro. | Foreign companies or branches should check double tax treaties and whether income taxed at source—or eligible for relief. |
| **Tax Administration** | A Central Liaison Office will facilitate information exchange; penalty and interest rate-related rules updated. | Companies must ensure compliance with transfer pricing, reporting, and information disclosure; audits will likely intensify. |
## What Entities Should Do Now
1. **Review intercompany lending** and ensure your interest payments meet the new documentation and arm’s-length tests. If not, adjust structure or budget expectations. |
2. **Check any operations with non-resident income**—royalties, dividends, services. Ensure withholding and reporting align with both Montenegro’s updated law and applicable treaties. |
3. **Update tax admin processes**—set up internal systems for exchange of information, maintain required records. |
4. **Monitor implementation dates**—some rules may come into force immediately, others (like profit tax changes) from **1 January 2027**.([gov.me](https://www.gov.me/cyr/clanak/novi-poreski-zakoni?utm_source=openai)) |
## Example Scenario
A foreign holding company lends EUR 1 million to its Montenegrin subsidiary. Prior rules allowed broad interest deduction. Under the new law, only interest at arm’s-length, properly documented, will be deductible. The holding may also owe withholding tax on interest unless treaty provisions apply.
## Strategic Takeaways
- Businesses operating cross-border with Montenegro must re-evaluate internal finance arrangements. |
- Where possible, re-structure to avoid excessive interest payments subjected to disallowance. |
- Use tax treaties to your advantage for both avoidance of double taxation and in defining withholding obligations. |
## Conclusion
Montenegro’s mid-2026 reforms mark a significant step toward EU-aligned tax rules, especially in corporate profit taxation and nonresident regimes. Companies with exposure to Montenegro must act promptly to align documentation, review financing structures, and plan for new tax deductibility criteria effective in 2027.
