This article will thoroughly cover Romania thin capitalization interest deductibility 2026 and its implications.

Understanding Thin Capitalization in Romania: The Core Problem

Companies, particularly those part of multinational groups, often finance their operations through a mix of equity and debt. When a company is predominantly financed by debt from related parties, rather than equity, it is considered "thinly capitalized." This structure can be advantageous as interest payments are typically tax-deductible, reducing the taxable base, unlike dividend payments. To prevent excessive debt financing from eroding the tax base, many countries, including Romania, implement thin capitalization rules.

Legal Framework: Romanian Fiscal Code Provisions

The fundamental provisions regarding interest deductibility, including thin capitalization rules, are enshrined in the Romanian Fiscal Code (Codul Fiscal), Law no. 227/2015, with subsequent amendments and completions. Specifically, Article 40 of the Fiscal Code, titled "Deductibility of expenses with interest and other costs assimilated to those with interest," outlines the general and specific limitations.

The General Interest Deductibility Limit (Rule based on EBITDA)

Romania adopted provisions stemming from the EU Anti-Tax Avoidance Directive (ATAD I and ATAD II) to align its tax rules with international best practices. Since January 1, 2018, Romania applies an earnings-before-interest-taxes-depreciation-and-amortization (EBITDA) based limitation for interest deductibility. This rule supersedes the former debt-to-equity ratio rule, although some specific provisions regarding related-party debt remain relevant in certain contexts.

According to Article 40, paragraph (1^1) of the Fiscal Code, expenses with interest and other costs assimilated to interest are deductible in the calculation of corporate income tax only up to an annual ceiling of EUR 200,000. If the deductible amount of expenses with interest and other assimilated costs exceeds this threshold, the excess is deductible up to 30% of the adjusted fiscal result.

Adjusted Fiscal Result (AFR) is calculated as: (Accounting profit or loss + specific non-deductible expenses (e.g., corporate income tax, non-deductible interest and assimilated costs, impairment adjustments concerning long-term assets, net expense related to fixed assets' scrapping/sale) - specific non-taxable income (e.g., non-taxable interest and assimilated income, income from adjustments relating to long-term asset impairment, income from fixed assets' scrapping/sale)).

• Carry-forward mechanism: Any non-deductible interest exceeding the EUR 200,000 threshold and 30% of AFR can be carried forward indefinitely. This is a crucial point for long-term financial planning and is stipulated in Article 40, paragraph (1^3) of the Fiscal Code. This carry-forward ability ensures that genuinely incurred interest may eventually be deductible, albeit delayed.

• Scope of application: These rules apply to both related party debt (as defined by Article 7, point 21 of the Fiscal Code) and third-party debt. This broad application means that all interest expenses, regardless of the creditor, are subject to these limitations.

What Constitutes "Costs Assimilated to Interest"?

It's not just explicit interest payments that are caught by these rules. The Fiscal Code, in Article 40, paragraph (1^5), specifies a broad range of costs assimilated to interest, including but not limited to:

• Costs related to the financing of leases.
• Capitalized interest included in the acquisition cost of an asset (for corporate income tax purposes, the capitalized interest will be treated as an interest expense in the period of capitalization).
• Net foreign exchange losses related to loans (under specific conditions).
• Guarantees and commissions related to loan financing.
• Any other costs that constitute consideration for the use of capital, even if not explicitly termed "interest."

This broad definition aims to prevent recharacterization of interest expenses into other forms to circumvent the limitation rules.

Specific Considerations for Romania Thin Capitalization Interest Deductibility 2026

While the general EBITDA-based rule is the primary mechanism, foreign investors should be aware of nuances and potential future developments related to Romania thin capitalization interest deductibility 2026.

Companies Exempted from the Interest Deductibility Rules

Certain entities are partially or entirely exempted from the EBITDA-based interest limitation rule, as per Article 40, paragraph (1^4) of the Fiscal Code:

Practical Implications and Planning for 2026

For foreign investors, understanding the Romania thin capitalization interest deductibility 2026 framework requires proactive financial planning:

• Debt-Equity Ratio Analysis: While not the primary limitation, a healthy debt-to-equity ratio from a commercial perspective can also mitigate risks from a financing perspective. Avoid excessive reliance on related-party debt, especially if the borrowing entity has low expected profitability.
• Profitability Projections: Closely monitor your Romanian subsidiary's projected Adjusted Fiscal Result (AFR). If AFR is low or negative, a significant portion of interest expenses may become non-deductible, increasing the effective tax burden.
• Cash Flow Management: Non-deductible interest means higher taxable profit, leading to higher corporate income tax payments, which impacts cash flow. Model this impact carefully.
• Loan Structuring: Consider the source and terms of loans. While no longer expressly preferring third-party debt for full deductibility, the commercial rationale for loans (e.g., arm's length principle for related-party loans) remains crucial under transfer pricing rules (Article 11 of the Fiscal Code).
• Documentation: Maintain meticulous documentation for all intragroup loans, including loan agreements, calculation of interest, and justification for the terms (transfer pricing documentation). This is vital for potential tax authority scrutiny.

Consequences of Non-Compliance: Penalties and Fines

Failure to correctly apply the thin capitalization rules and interest deductibility limits can lead to significant financial penalties and increased tax exposure.

Romanian Fiscal Procedure Code (Codul de Procedură Fiscală), Law no. 207/2015, governs tax audits and penalties:

• Re-qualification of expenses: The tax authorities may re-qualify non-deducted interest expenses, disallowing them entirely or partially, leading to an increase in corporate income tax due.
• Late payment penalties: For additional corporate income tax identified during an audit, late payment interest and penalties will be applied. According to Article 174 of the Fiscal Procedure Code, late payment interest is 0.02% per day of delay. A penalty for non-declaration or incorrect declaration, as per Article 181 of the Fiscal Procedure Code, can range from 0.06% to 0.08% per day depending on the specific violations, in addition to late payment interest.
• Fines for incomplete/incorrect declarations: Any misstatement or omission in tax declarations can trigger administrative fines. For example, substantial errors can lead to fines ranging from RON 500 to RON 5,000 (approx. EUR 100-1,000) for legal entities, as per Article 337 of the Fiscal Procedure Code.
• Reputational damage: Non-compliance can lead to a negative reputation with tax authorities, potentially triggering more frequent and stringent audits.

Required Documents and Deadlines for Interest Deductibility

While there is no specific annual declaration solely for thin capitalization, the correct application of these rules is reflected in the statutory corporate income tax return (Formular 101 – Declarație privind impozitul pe profit), which must be filed annually.

Key Documents to Maintain:

• Loan agreements: Detailed contracts for all loans, clearly stating principal, interest rate, repayment schedule, and parties involved.
• Amortization tables: Schedules showing interest and principal repayments.
• Bank statements: Proof of interest payments.
• Transfer pricing documentation: For related-party loans, this includes a comparability analysis, proving that the interest rate and loan terms are arm's length (Article 11 of the Fiscal Code and ANAF Order no. 442/2016 regarding the content of transfer pricing documentation).
• Financial statements: The calculation of the Adjusted Fiscal Result (AFR) is derived from the company's financial statements.
• Internal calculation worksheets: Documenting how the deductible interest was calculated, including the EUR 200,000 threshold and 30% AFR limit.

Deadlines:

• Annual Corporate Income Tax Return (Formular 101): Generally due by the 25th day of the third month following the end of the fiscal year. For companies with a calendar fiscal year, this means March 25th of the following year (e.g., March 25, 2027, for the 2026 fiscal year). According to Article 41, paragraph (1), letter a) of the Fiscal Code.
• Quarterly/monthly advance payments: Depending on the company's chosen system, advance payments of corporate income tax are due by the 25th day of the month following the quarter/month, with the final adjustment being made in the annual return.

Practical Advice from an Experienced Lawyer's Perspective

The following practical information concerns Romania thin capitalization interest deductibility 2026 for foreign investors:

Frequently Asked Questions (FAQs)

Q1: Do the thin capitalization rules apply to third-party loans as well?

Yes, unlike some historical rules, the current EBITDA-based limitation (EUR 200,000 + 30% of AFR) applies to all interest expenses, regardless of whether the loan is from a related party or a third party. This is explicitly stated in Article 40, paragraph (1^1) of the Fiscal Code.

Q2: Is there a maximum period for carrying forward non-deductible interest?

No, one of the key benefits of the current Romanian regime is that non-deductible interest and assimilated costs can be carried forward indefinitely. This is provided under Article 40, paragraph (1^3) of the Fiscal Code.

Q3: How is the "Adjusted Fiscal Result" (AFR) calculated?

The Adjusted Fiscal Result (AFR) is a specific tax concept. It's broadly calculated as: Fiscal Profit/Loss before considering interest, income tax, depreciation, amortization, and certain impairment adjustments. A precise calculation is crucial and involves accounting profit adjusted for various non-deductible expenses and non-taxable incomes, as detailed in Article 40, paragraph (1^2) of the Fiscal Code.

Q4: Are there any industries or types of businesses exempt from these rules?

Yes, financial institutions and insurance/reinsurance companies, as well as companies involved in certain public utility infrastructure projects under specific conditions, may be partially or fully exempt from the 30% of AFR limitation. They generally remain subject to other tax rules or specific industry regulations. Refer to Article 40, paragraph (1^4) of the Fiscal Code for details.

Q5: What is the main difference between the old and new thin capitalization rules?

The primary difference is the shift from a debt-to-equity ratio test (old rule, primarily for related parties) to an EBITDA-based limitation (current rule, for all parties). The current rule also introduces a fixed EUR 200,000 threshold and an indefinite carry-forward period for non-deductible interest. This distinction is vital for understanding Romania thin capitalization interest deductibility 2026.

Q6: What if my Romanian subsidiary generates a loss? How does this impact interest deductibility?

If your Romanian subsidiary generates a fiscal loss, its Adjusted Fiscal Result (AFR) will likely be negative or very low. In such cases, only the fixed EUR 200,000 threshold would typically be deductible. Any interest exceeding this amount would be non-deductible and carried forward indefinitely until sufficient AFR is generated in future periods. This highlights the importance of profitability for full interest deductibility.

Q7: Can capitalized interest (e.g., on construction loans) be deducted?

Yes, interest that is capitalized into the cost of an asset (e.g., during a construction period) is still considered an interest expense for corporate income tax purposes in the period of capitalization and is subject to the general deductibility limits under Article 40 of the Fiscal Code. It is not treated as part of the asset's depreciable cost for tax purposes from a deductibility stand-point, but rather as an interest expense subject to the annual limitations.

Q8: What role does transfer pricing play with these rules?

While the thin capitalization rules directly limit the amount of deductible interest, transfer pricing rules (Article 11 Fiscal Code) determine if the interest rate itself on related-party loans is at arm's length. If the interest rate is deemed non-arm's length, the excess interest charged can be re-qualified and disallowed, before the application of thin capitalization rules. Therefore, both sets of rules are crucial and often apply concurrently to related-party debt.
