Why the price? transfer pricing services Is there a price discrepancy? This is a question that puzzles many CFOs and Chief Accountants when preparing related-party transaction documentation for the 2026 tax season. On the market, consulting fees can range from a few million VND to hundreds of millions VND, or even billions of VND for multinational corporations. However, behind this price difference lies not only the cost of services but also the quality of comparative data, the expertise of the specialists, and the level of legal security during tax audits. This article will analyze why transfer pricing service prices vary and warn of the serious risks businesses may face if they choose low-quality, cheap services during the 2026 tax season.
Why is transfer pricing documentation no longer just a formality?
Entering 2026, the Vietnamese tax authorities have completed a Big Data system combined with artificial intelligence to screen businesses showing signs of transfer pricing. Decree 132/2020/ND-CP, along with the latest updates from Decree 20/2025/ND-CP and Global Minimum Tax Mechanism (Pillar Two) OECD regulations on related-party transactions have established a strict technical barrier.
Transfer Pricing Documentation is now more than just a document to submit when requested; it is the sole legal evidence a business can use to protect its interests. The introduction of the Automatic Exchange of Information (AEOI) mechanism allows the General Department of Taxation to fully understand the financial picture of the parent company abroad. Therefore, if the documentation in Vietnam is inconsistent with the Country-by-Country Report of Profits (CbCR), the risk of tax arrears is real and extremely high. The 2026 tax filing season is predicted to be a "hot spot" for inspections, especially for FDI businesses with consistently negative profits but still expanding production.
Why is there such a large difference in transfer pricing service fees between different consulting firms?
To understand why transfer pricing services vary, let's explore the components that make up the value of a well-prepared portfolio with MAN – Master Accountant Network. There's no fixed price for professional quality, but key factors create the difference:
Factor 1: Database Benchmarking Licensing Costs
This is considered the "heart" of the transfer pricing documentation. According to the Arm's Length Principle, businesses must demonstrate that their profit margin falls within the benchmark range of comparable independent companies.
- Reputable providers: They use copyrighted global databases such as Orbis (Moody's), Bloomberg, or specialized data for specific industries. Maintaining these accounts can cost tens of thousands of USD annually. The extraction of accurate, up-to-date data up to the current fiscal year is the reason for the higher service price.
- Low-cost providers: These often use "illegible" data, outdated data from previous years, or fabricated figures from unreliable financial reports. When tax authorities verify the tax identification numbers of comparable businesses, these records are immediately rejected due to a lack of objectivity and timeliness.
Factor 2: Professional qualifications and practical experience
The difference between a regular service accountant and a transfer pricing specialist (TP Specialist) is significant.
- A high-quality filing requires expertise in global value chains, functional, asset, and risk (FAR) analysis, and sophisticated econometric methods. Senior professionals are able to justify losses due to market factors or startup costs, which less experienced firms often overlook, leading to the company accepting unfair tax assessments.
- The difference in transfer pricing service fees also lies in the ability to "litigate." The real value lies in whether the consulting firm has the courage and knowledge to defend its arguments in the documentation when the inspection team arrives.
Factor 3: Scope of work
Many businesses confuse "creating an appendix" with "creating documentation".
- Low-cost service: Only assists in filing related party transaction declarations (Appendices I, II, III, IV) according to the tax authority's template. This is only the initial declaration step.
- Professional service: Includes a 3-level documentation package in accordance with international regulations: Local File, Global Corporate File (Master File), and Country-Based Profit and Loss Report (CbCR). They conduct a detailed FAR Analysis (Functions, Assets, Risks) to identify and address risk gaps before final settlement.
Factor 4: Commitment to partnership and after-sales service
Transfer pricing doesn't end when the documents are handed over. It really begins when the tax authorities send an inspection notice. Low-cost firms often disappear or refuse to assist with explanations because the low cost isn't enough to justify their time working with the inspection team. Conversely, reputable firms will commit to supporting the business throughout the post-audit process, protecting the data and interests of the business to the very end.
Comparing transfer pricing service segments in the market.
To better understand why transfer pricing services vary so significantly in the market, businesses need to consider the differences in data quality, depth of specialized analysis, scope of support, and the level of legal security offered by each group of consulting firms. In reality, service costs not only reflect the effort involved in preparing the documentation but also the source of copyrighted data, practical experience, and the ability to protect the documentation during tax audits. The comparison table below will help businesses gain an overview of the three most common transfer pricing service segments currently available on the market.
| Criteria | The Big4 | Tier 2 Group | Budget group |
| Data quality | Absolutely accurate, international copyright. | Accurate, copyrighted data. | Source unknown, old, outdated data. |
| Depth of analysis | Very deep, multi-dimensional. | In-depth analysis, closely reflecting the current realities of the business. | Shallow, copied from the template. |
| Fee | Very high | Reasonable | Extremely low |
| Legal safety | Very high | High | Very low (easily subject to assessment and tax recovery due to unconvincing documentation) |
| Inspection Support | Professional | Dedicated and attentive | Avoiding responsibility, lacking the capacity to provide an explanation. |
As the comparison table above shows, the difference in transfer pricing service fees is not random but directly reflects the level of expertise, data quality, and ability to protect businesses from tax audit risks. Reputable international or domestic consulting firms often invest heavily in copyrighted databases, expert teams, and in-depth analytical processes, thereby providing a higher level of legal security for businesses.
Conversely, cheap services often only go as far as copying sample documents or using unreliable comparative data, making the documents easily rejected by tax authorities during audits. In many cases, the initial cost savings are only a few tens of millions of dong, but this can lead to a very high risk of being overcharged and having to pay back taxes later on.
Therefore, when evaluating transfer pricing services, businesses should not only compare prices but also consider the true value of the documentation: accurate data, proper analytical methods, and the ability to provide support during tax audits. These are the decisive factors that help businesses minimize risks and ensure sustainable compliance during tax season.
Warning about the risks and penalties of choosing cheap services.
Many FDI businesses, in their pursuit of short-term cost savings, have fallen into the trap of "cheap prices." However, reality shows that excessively low transfer pricing service prices always come with a corresponding level of risk. Below are the specific risks and penalties that businesses face:
Risk of Rejection of Tax Filing and Assessment
This is the most serious risk. When a low-cost service provides an "empty" package (lacking benchmarked data or using incorrect methodology for analysis):
- Consequence: The tax authorities have the right to completely reject the company's application according to Article 20 of Decree 132/2020/ND-CP.
- Imposed penalty: The tax authorities will use their own data (usually the highest profit margins in the industry) to determine the corporate income tax payable. Businesses lose their autonomy and the right to apply favorable market transaction value ranges.
Administrative penalties and late payment fees
According to Decree 125/2020/ND-CP Regarding administrative penalties for tax violations, the fines for acts related to related-party transactions are very heavy:
- Penalty for false declaration: A penalty of 20% will be applied to the additional tax amount after inspection/audit.
- Late payment penalty: Calculated at a rate of 0.031 TP3T/day on the amount of tax overdue. For tax arrears cases spanning 3-5 years, the late payment penalty can amount to 40-501 TP3T of the original tax amount.
- Penalties for failure to submit documents or submitting them late: The fine ranges from VND 8,000,000 to VND 25,000,000. However, this figure is only the tip of the iceberg compared to the total amount of back taxes and assessed taxes.
Risk of being constrained by interest expense.
Low-cost services often fail to provide thorough advice on optimizing interest expense coverage within the 30% EBITDA ceiling.
- Risk: If calculations are incorrect or there is no documentation proving the reasonableness of the linked loan, the entire excess interest expense will be disallowed as a deductible expense. For FDI enterprises that are heavily reliant on borrowed capital, the additional corporate income tax payable could amount to tens of billions of VND.

Adding businesses to the high-risk "blacklist"
Submitting a low-quality, error-filled transfer pricing document is a sign that the business lacks a commitment to compliance.
- Consequence: The business will be classified as high-risk for tax purposes. This means the business will be subject to tax audits and inspections more frequently (possibly annually) instead of every 3-5 years like businesses that comply well.
How to choose the right transfer pricing consulting firm.
Before deciding to sign a contract, ask yourself the following questions to understand why transfer pricing services vary and choose the right partner:
- Database: “Which comparative data sources does the organization use? Is there a license for updates for the period 2025-2026?”
- Team: Who will directly conduct the economic analysis, assess the current state of the business, and determine the most optimal course of action? Do they possess professional certifications or practical inspection experience?”
- Process: "Is there a direct survey at the business, a review of all transactions to identify related-party transactions, or are we just relying on figures provided by the business via email?"
- Responsibility: “If the tax authorities reject the comparative method, how will the unit support the explanation?”
Conclude
In the context of tax authorities tightening regulations on related-party transactions and increasing inspections of FDI enterprises, understanding the reasons for the discrepancies in transfer pricing service fees is crucial for businesses to choose the right service provider. Reliable transfer pricing consultancy, This not only improves quality but also contributes to minimizing long-term legal risks. In fact, the cost of the service is not simply the fee for preparing the application, but also reflects the quality of comparative data, the depth of economic analysis, and the ability to defend the application against tax authorities.
Choosing a low-cost service might save initial costs, but if the documentation is substandard or rejected during an audit, the business could face late payment penalties, back taxes, and even an overestimation of corporate income tax. Conversely, a well-prepared transfer pricing documentation will help the business demonstrate the legitimacy of related-party transactions, minimize audit risks, and optimize its tax strategy legally.
Therefore, when preparing for the 2026 tax season, businesses should proactively reassess their related-party transaction records and choose a consulting firm with practical experience, copyrighted data, and a commitment to supporting them throughout the tax audit process. This is a necessary investment to protect the financial stability and legal reputation of the business in an increasingly stringent tax management environment.
