- Parties are jointly under the management, control, capital contribution or investment of another party (directly or indirectly).

Decree 20/2017/ND-CP on related-party transactions regulates control of loan interest expenses

- Total net interest expense (interest expense after deducting deposit interest and loan interest) of an enterprise that is deductible when calculating corporate income tax does not exceed 20% of total net profit from business operations plus interest expense and depreciation expense (similar to EBITDA indicator).
In other words, a business can only calculate a maximum of 20% of net interest expenses into deductible expenses, the excess amount will not be deductible when determining taxable income.
Mechanism for transferring excess interest expense
The interest expense exceeding the 20% limit is not completely lost, but is carried forward to the next tax period (up to 5 years). Therefore, the enterprise still has the opportunity to record this expense in the future if it has a profit large enough to absorb the excess amount.
Regulatory restrictions
Decree 20/2017/ND-CP on related-party transactions is the first legal document at the Decree level issued by the Government to manage taxes on related-party transactions and prevent transfer pricing. The issuance of this Decree marks an important step forward in bringing Vietnam's regulations closer to international practices, in the context of increasingly sophisticated and complex transfer pricing and tax avoidance behaviors of multinational corporations.
“The current corporate income tax policy provides for tax incentives and exemptions for industries, sectors, and localities. Corporations take advantage of differences in tax rates, incentives, and tax exemptions to transfer profits between domestic corporations to evade taxes. In addition, some domestic corporations also arrange transactions and transfer pricing to transfer profits to corporations that are operating at a loss (with losses to be transferred); transfer profits from profitable enterprises to loss-making enterprises to evade taxes.
Transfer pricing and profit transfer not only occur in FDI enterprises but also appear in domestic enterprises because even in domestic operations, Vietnamese enterprises have invested in many industries and fields such as trade, services, production... Obviously, even domestically, there is a phenomenon of transferring profits from enterprises and locations with high tax rates to enterprises and locations with low tax rates; transferring profits from profitable enterprises to loss-making enterprises"

Comparison of Decree 20/2017/ND-CP on related party transactions and Decree 132/2020/ND-CP
In the process of tax management for related-party transactions, Decree 20/2017/ND-CP on related-party transactions is considered the first legal basis. However, the implementation has revealed many limitations, especially the regulation on controlling loan interest expenses 20%. To overcome and approach international practice, the Government issued Decree 132/2020/ND-CP with many important innovations. The table below will help you clearly visualize the differences and connections between these two decrees.
| Criteria | Decree 20/2020/ND-CP | Decree 32/2020/ND-CP | Change points and significance |
| Main objective | Anti-transfer pricing, tax management with related transactions | Perfecting the mechanism, in line with international practices (BEPS), reducing shortcomings of Decree 20 | Increase transparency, balance interests |
| Control interest costs | Up to 20% EBITDA | Up to 30% EBITDA | Support businesses, reduce loan burden |
| Transfer pricing determination dossier | Requested to be established, but not yet synchronized | Clearly defined according to BEPS standards: Local file, Master file, CbCR | Transparency, international integration |
| Country-by-Country Reporting (CbCR) | Yes, but not in detail | Clearly stated: The parent company in Vietnam with revenue ≥18,000 billion must pay | Clear multinational corporate responsibility |
| Principles of application | Independent transaction, nature determines form | Inheriting the principles of Decree 20, but more detailed and stricter | Increase the effectiveness of anti-transfer pricing |
| Impact on business | Being reflected causes difficulties, especially regulation 20% loan interest | More open, but still tightening anti-transfer pricing | Balance between management & business support |
Through the comparison table, it can be seen that Decree 132/2020/ND-CP not only inherits the foundation from Decree 20/2017/ND-CP on related-party transactions but also completes and adjusts many regulations to be more suitable to reality. These changes help businesses have a clear and transparent legal basis in declaring and determining transfer pricing, while creating conditions for tax authorities to enhance management efficiency and prevent budget losses.
