Decree 132/2020/ND-CP was issued to combat transfer pricing, prevent the erosion of the tax base, and stop profit shifting through the artificial inflation of interest expenses. Article 16, Clause 3 of this Decree, which regulates the limitation of interest expenses, creates a ceiling at which businesses are compelled to understand the true nature of EBITDA as defined in Decree 132.
Simply put, according to Decree 132, EBITDA is a measure of profit before interest, taxes, and depreciation accepted by the tax authorities as a basis for calculating the deductible interest expense threshold. If actual interest expense exceeds this threshold (30% EBITDA), the excess amount will not be considered a deductible expense when settling corporate income tax. This is a crucial point that every Chief Accountant and CFO needs to understand to avoid the risk of tax arrears.
What is EBITDA according to Decree 132? And how to determine it accurately?

Many businesses often confuse EBITDA in conventional corporate financial management with EBITDA as defined by Decree 132. In a legal context, businesses need to strictly adhere to the formula stipulated in Article 16 to ensure that the figures included in the tax return are transparent.
| Indicators | Meaning |
| Profit from business operations (HĐSXKD) | Net income from core business operations (before interest and taxes). |
| Interest expense | All interest expenses incurred by the business during the period. |
| Depreciation expense | Total depreciation expense of fixed assets and allocation of investment properties during the period. |
General formula:
According to Decree 132, EBITDA = Profit from business operations + Interest expense + Depreciation expense |
Note: When determining the components in the EBITDA formula according to Decree 132, these figures must be taken directly from the audited or tax-settled Income Statement. Incorrectly extracting depreciation or interest expense figures between accounting records will lead to inaccurate EBITDA calculation according to Decree 132, resulting in incorrect calculation of the deductible interest expense limit.
Practical example: Calculating interest rate limits based on EBITDA
To help you visualize this, consider the following specific example of a business with related-party transactions:
Let's assume the data is for 2025:
- Profit from business operations: 5,000,000,000 VND
- Interest expense: 2,000,000,000 VND
- Depreciation cost: 1,000,000,000 VND
Calculate EBITDA according to Decree 132:
EBITDA according to Decree 132 = 5,000,000,000 + 2,000,000,000 + 1,000,000,000 = 8,000,000,000 VND |
Calculate the limit for deductible interest expense under code 30%:
Ceiling amount = EBITDA x 30% = 8,000,000,000 x 30% = 2,400,000,000 VND |
Result: The company has actual interest expense of VND 2 billion, but the EBITDA ceiling is higher than the actual interest expense. The company will be entitled to a deduction. all interest expenses during the corporate income tax period.
Detailed analysis of application scenarios
The application of the EBITDA regulations under Decree 132 does not apply to all cases:
Exempted subjects
Loans under national target programs, preferential loans from the government, or public projects are generally outside this scope. Therefore, before calculating EBITDA according to Decree 132, accountants need to review the entire loan portfolio to exclude those not subject to adjustment.
Handling situations when a business incurs losses or negative profits.
This is the most complex situation. When the EBITDA target under Decree 132 is zero or negative, it means the business has no limit on deductible interest expense (according to the 30% limit). However, businesses need to be aware of the regulation allowing the carry-forward of non-deductible interest expense to the next period. Strict management of this balance requires absolute accuracy in monitoring EBITDA under Decree 132 annually.
Optimizing EBITDA according to Decree 132 to ensure maximum interest expense.
Instead of trying to circumvent the law, the smart strategy is to optimize capital structure. Businesses should maintain a reasonable debt-to-equity ratio to ensure that EBITDA, as per Decree 132, always meets safe thresholds. This will maximize the use of the 30% ceiling on deductible interest expenses, helping to legally optimize corporate income tax payable.
