Cambodia is tightening its tax compliance and financial reporting framework in 2026, with new rules affecting capital gains taxation, transfer pricing, mandatory independent audits and penalties for late payments and filings. Tax experts from DFDL and the European Chamber of Commerce in Cambodia (EuroCham) highlighted the changes at a breakfast briefing in Phnom Penh on October 6, urging businesses and non-governmental organisations (NGOs) to reassess their obligations before the end of the year.
The regulatory changes include sector-specific thresholds for mandatory audits, expanded coverage of certain business categories regardless of size, and stricter requirements for companies conducting transactions with related parties. Businesses that fail to comply may face additional tax assessments, penalties and interest, while some entities seeking audit exemptions must act within a limited timeframe.
Key Facts

Organisers: DFDL and EuroCham Cambodia.
Capital gains tax: A 20% tax applies to taxable gains from specified capital assets under the regime described at the briefing, with different implementation timelines for certain asset classes.
Transfer pricing: The General Department of Taxation (GDT) may scrutinise related-party transactions and adjust pricing.
Audit requirements: Prakas 063, signed on August 18, 2026, introduces revised thresholds for annual financial statement submissions and independent audits.
Newly covered categories: Certain foreign company branches, casino operators and larger property developers are included regardless of size under the rules described at the briefing.
Audit exemption window: Eligible businesses and NGOs must apply within 30 days after the end of their accounting year.
Late-payment penalties: The briefing described penalties that double after 30 days of non-payment and triple after 60 days.
1. Cambodia's Tax Compliance Framework Is Becoming More Demanding
The October 6 briefing brought together chief financial officers, tax directors, chief accountants, in-house legal counsel and representatives of NGOs to discuss changes to Cambodia's tax, transfer pricing and accounting requirements.
DFDL specialists explained how the regulatory developments could affect companies with cross-border operations, related-party transactions and complex financing arrangements. The session also addressed changes to mandatory independent audits, an area with direct implications for financial reporting and year-end compliance planning.
For businesses, the changes mean that compliance reviews should go beyond calculating annual tax liabilities. Companies may also need to reassess their reporting obligations, transaction documentation, audit status and eligibility for exemptions.
The exact obligations depend on the applicable regulation, the entity's activities and financial circumstances. Businesses should therefore verify the rules that apply to their own operations rather than relying on a general checklist alone.
2. Capital Gains Tax: A 20% Rate for Specified Assets
DFDL tax partner Vajiravann Chamnan highlighted Cambodia's capital gains tax regime, which imposes a 20% tax on taxable capital gains from specified capital assets, including share transfers, investment assets, goodwill and intellectual property.
The briefing also noted that different implementation timelines apply to certain asset classes. Filing is due within three months of a sale, according to the source report.
For businesses and investors, the rules make it important to identify whether a proposed disposal falls within the regime and how the taxable gain should be calculated.
Potentially affected transactions include:
Transfers of company shares.
Disposals of investment assets.
Transactions involving goodwill.
Transfers of intellectual property.
Companies considering mergers, acquisitions, restructuring or asset disposals should review the tax implications before completing a transaction. The applicable treatment and timing should be confirmed for the particular asset and transaction, because the briefing did not provide a complete breakdown of implementation dates or calculation rules for every asset class.
3. Tax Liabilities May Follow Business Restructuring
The briefing also covered rules clarifying responsibility for unpaid taxes when a business is sold, merged or transfers its shares.
According to the statement cited in the report, tax debts may remain associated with the entity that survives a transaction or with an entity that has not been properly deregistered.
This issue is relevant to buyers, sellers and companies undergoing restructuring. A transaction that changes ownership or legal structure does not necessarily eliminate existing tax exposure.
Before completing a business acquisition or restructuring, companies should consider reviewing outstanding tax liabilities, filing history, unresolved assessments and deregistration requirements.
For buyers, tax due diligence can help identify potential liabilities that might otherwise emerge after completion. Sellers should also ensure that required tax filings and corporate procedures are properly addressed.
The briefing did not specify every circumstance in which liability transfers or remains with a particular entity. Businesses should obtain advice based on the transaction structure and applicable rules.
4. Transfer Pricing: Related-Party Transactions Face Greater Scrutiny
Transfer pricing was another major topic at the briefing. DFDL tax partner Vajiravann Chamnan said the General Department of Taxation may scrutinise transactions between related companies, including:
Intercompany loans.
Management fees.
Sales of goods between related entities.
Royalty and licensing payments.
These transactions can attract scrutiny when the prices or terms do not reflect the arm's-length principle—the standard that related parties should transact on terms comparable to those that independent parties would agree under similar circumstances.
If the GDT determines that a transaction's pricing is inappropriate, the resulting adjustment may increase a company's taxable income or otherwise affect its tax position.
Chamnan identified possible consequences of an unsuccessful audit, including the disallowance of related-party expenses, additional tax assessments and penalties ranging from 10% to 40%, plus monthly interest. In serious cases involving deliberate tax evasion or fraud, further enforcement measures may apply.
The precise consequences depend on the circumstances and applicable provisions; the reported ranges should not be interpreted as a single penalty automatically applying to every transfer pricing adjustment.
What businesses should review
Companies with related-party transactions should examine whether their pricing and contractual arrangements are supported by adequate evidence.
Practical steps include:
Map related-party transactions: Identify payments, loans, services, royalties and goods exchanged with related entities.
Review pricing methods: Check whether the terms can be supported under the arm's-length principle.
Maintain supporting records: Keep contracts, invoices, calculations and other evidence that explains how prices were determined.
Review exposure regularly: Reassess arrangements when business conditions, transaction values or applicable thresholds change.
These measures can help companies prepare for questions from tax authorities and identify weaknesses before a formal review.
5. Prakas 574: Transfer Pricing Adjustments and Relief Regimes
DFDL transfer pricing lead Vandana Vijayakumar discussed Prakas 574, which addresses transfer pricing requirements and related adjustments.
According to the briefing, an upward pricing adjustment may create a second layer of tax exposure if the difference is reclassified as a dividend, loan or capital contribution.
This means businesses should not assess transfer pricing adjustments solely by looking at the immediate change to taxable income. They should also consider whether the adjustment could affect the classification and treatment of the underlying funds or transaction.
Vijayakumar described two separate relief regimes:
A documentation relief regime: Qualifying companies may be exempt from preparing full transfer pricing documentation when they meet the applicable financial thresholds.
A related-party loan relief regime: A narrower exemption applies to certain related-party loans.
Both regimes must be reassessed annually, according to the briefing.
The exemptions are not interchangeable. A company qualifying for one form of relief should not assume it also qualifies for the other.
Vijayakumar advised businesses to map related-party transactions, reassess thresholds and exemptions each year, and retain documentation supporting the arm's-length nature of their arrangements.
For companies with frequent intercompany financing or cross-border dealings, this review should form part of their regular tax compliance process.
6. Prakas 063 Revises Mandatory Audit Requirements
One of the most significant accounting developments discussed at the event was Prakas 063, signed on August 18, 2026.
Accounting director Michelle Cielo said the regulation sets out which entities must submit annual financial statements and undergo an independent audit.
The new rules raise turnover and asset thresholds that trigger mandatory audits, with sector-specific thresholds introduced for the first time, according to the report.
As a result, some small and medium-sized enterprises that fell within the previous requirements may no longer be subject to mandatory audits under the revised thresholds.
However, the changes do not mean that all smaller businesses are automatically exempt. Audit obligations depend on the applicable sector, financial criteria and entity category.
Entities that need particular attention
Cielo highlighted several categories that are newly covered regardless of size under the rules described at the briefing:
Branches of foreign companies.
Casino operators.
Larger property developers.
NGOs face separate triggers based on factors including project cost, overall expenditure and staff numbers.
These distinctions matter because a company may not be able to determine its audit obligations from turnover or assets alone. Its legal form, sector and other criteria may also be relevant.
The source report did not provide the complete numerical thresholds for each sector or category. Businesses should consult the full text of Prakas 063 and confirm the applicable requirements before concluding that an audit is no longer necessary.
7. The 30-Day Audit Exemption Window
The briefing also highlighted a strict deadline for eligible businesses and NGOs seeking an exemption from the relevant audit requirements.
According to Cielo, entities that fall outside the new thresholds can apply for an exemption, but the application must be made within 30 days after the end of their accounting year.
This makes the accounting year-end an important compliance date. An entity that qualifies for relief but misses the application window may face a different compliance position from one that applies on time.
Businesses should establish who is responsible for assessing eligibility, preparing the application and confirming submission.
A practical year-end checklist should include:
Confirming the entity's accounting year-end.
Reviewing the applicable sector and financial thresholds.
Checking whether the entity falls within a category covered regardless of size.
Assessing whether an exemption is available.
Preparing and submitting any required application within the prescribed window.
Retaining evidence of submission and the relevant supporting records.
The 30-day period should be verified against the full regulation and the entity's circumstances. Businesses should not assume that simply falling below an audit threshold automatically grants an exemption.
8. Late Payments and Filings Can Become More Expensive
The briefing warned that penalties for late compliance can escalate quickly.
Cielo said penalties double after 30 days of non-payment and triple after 60 days, with further enforcement action possible beyond that point.
These escalating consequences increase the importance of monitoring payment obligations and filing deadlines. A delay that initially appears manageable may create a substantially larger financial exposure if it remains unresolved.
Companies should distinguish between payment deadlines, financial statement submission deadlines and any separate exemption application deadlines. Each may have different requirements and consequences.
Finance teams can reduce the risk of missed obligations by maintaining a compliance calendar, assigning responsibility for each filing and payment, and escalating potential delays before deadlines expire.
The report did not specify the original penalty amounts or provide a complete schedule of every sanction. Businesses should verify the applicable calculation and legal basis rather than assume that the same multiplier applies uniformly to all tax and accounting violations.
9. Intercompany Funding and Loans Remain a Practical Concern
During a question-and-answer session moderated by DFDL tax partner Diberjohn Balinas, participants raised questions about routine funding between related companies.
Topics included loans and cash advances from head offices, shareholders or sister companies, as well as how to establish a fair interest rate.
These arrangements can raise both transfer pricing and tax classification questions. The appropriate treatment may depend on the nature of the funding, the relationship between the parties, the contractual terms and the evidence supporting the interest rate.
Businesses should ensure that funding arrangements are properly documented and that their accounting treatment is consistent with the underlying transaction.
Useful records may include loan agreements, repayment terms, interest calculations, evidence of fund transfers and documentation explaining how the interest rate was determined.
Companies should also consider whether a funding arrangement is genuinely debt or could be treated differently under the applicable rules. The source report did not provide definitive answers to the individual questions raised at the event, so the treatment of a particular arrangement should be confirmed separately.
10. A Practical Compliance Checklist for Cambodian Businesses
The changes discussed at the briefing give businesses several areas to prioritise before year-end.
| Compliance area | Recommended action |
|---|---|
| Capital gains tax | Review planned disposals and confirm the applicable tax treatment and filing deadline. |
| Business restructuring | Check unpaid tax liabilities and deregistration requirements before a sale, merger or share transfer. |
| Transfer pricing | Map related-party transactions and maintain evidence supporting arm's-length pricing. |
| Exemptions | Reassess documentation and related-party loan relief annually. |
| Independent audits | Review the requirements under Prakas 063 using the entity's sector, legal form and financial data. |
| NGOs | Check the separate criteria involving project cost, expenditure and staffing. |
| Exemption applications | Confirm eligibility and meet the 30-day window after accounting year-end where applicable. |
| Payments and filings | Track deadlines and address potential delays promptly to reduce penalty exposure. |
| Intercompany financing | Document loans, cash advances, repayment terms and interest-rate calculations. |
This checklist is a starting point, not a substitute for reviewing the full regulations. The specific thresholds, exceptions and deadlines must be confirmed against the rules applicable to each entity.
Angkor Times Analysis: Compliance Planning Becomes a Business Priority
The regulatory changes described at the DFDL-EuroCham briefing point to a more detailed compliance environment for companies operating in Cambodia. The impact will vary: some smaller enterprises may fall outside mandatory audit thresholds, while foreign company branches, casino operators, property developers and certain NGOs may face obligations that cannot be assessed by size alone.
For businesses with cross-border operations, related-party transactions and intercompany financing, the key challenge is maintaining a clear record of how transactions are structured, priced and reported.
The changes also highlight the importance of coordination between finance, accounting, legal and management teams. Capital gains tax, transfer pricing, audit requirements and corporate restructuring can overlap, meaning that a decision in one area may create obligations in another.
Companies should therefore prioritise three actions: verify their status under the latest regulations, establish a reliable calendar for filings and payments, and maintain documentation that supports their tax positions.
The most important limitation is that the briefing report does not reproduce the full numerical thresholds or every provision of Prakas 574 and Prakas 063. Businesses should consult the official regulations and qualified Cambodian tax advisers before making decisions based on the reported changes.
