How Cambodia’s accounting and auditing infrastructure — standards, regulation, talent, and firm capacity — shapes the country’s competitiveness for foreign direct investment over the next five years, benchmarked against ASEAN peers.

Executive Summary

As Cambodia enters a period of intensifying regional competition for foreign direct investment, the quality and credibility of its accounting and auditing infrastructure has moved from a back-office compliance matter to a front-line determinant of investor confidence. Between 2026 and 2031, three forces will decide whether accounting and audit services function as a genuine comparative advantage for Cambodia rather than a bottleneck: the completeness of IFRS convergence, the depth and independence of the licensed audit market under the Accounting and Auditing Regulator (ACAR), and the pace at which the profession’s talent base scales to match investment volume.

Cambodia’s position is genuinely favourable on paper. It has adopted IFRS Accounting Standards without local modification, operates a single unified professional body in the Kampuchea Institute of Certified Public Accountants and Auditors (KICPAA), and has stood up a dedicated sectoral regulator in ACAR with its own licensing, quality-assurance, and enforcement functions — a more unified architecture than several larger ASEAN peers can claim. Full foreign ownership is permitted for most Qualified Investment Projects, and the accounting profession itself is open to standards convergence without the multi-year transition timelines some neighbours still carry.

The gap is not in the rules but in the market that applies them: as of early 2026, ACAR had licensed roughly 131 accounting and auditing firms nationwide, a majority of them small practices concentrated in Phnom Penh, with international network membership still limited to a handful of firms. For investors, that translates into a comparative advantage that is real but shallow — strong on paper, thin in bench depth. This article sets out where that advantage currently stands, how it compares with regional peers, and what would need to change for it to hold through 2031.

1. Why Accounting and Auditing Infrastructure Matters to Investors

Foreign investors evaluating a jurisdiction rarely treat accounting and auditing as a standalone consideration. It is embedded in almost every other decision they make: whether reported financial statements can be relied upon for a valuation or a loan covenant, whether a joint-venture partner’s books can be trusted, whether tax exposure can be quantified with confidence, and whether an eventual exit — a trade sale, an IPO, or a repatriation of capital — will be recognised by counterparties and regulators outside Cambodia. In this sense, the accounting and auditing profession functions as connective tissue between the domestic economy and the global capital that Cambodia is trying to attract.

Cambodia’s own experience over 2025–2026 illustrates the point. Investment approvals accelerated sharply, with the Council for the Development of Cambodia approving several hundred fixed-asset projects worth billions of dollars across manufacturing diversification, agro-processing, electronics, and logistics. Much of this is described by investors and business chambers as “China+1” diversification — capital that could as easily have gone to Vietnam, Indonesia, or the Philippines. In a competition of that kind, the credibility of financial reporting and the reliability of audit sign-off are not incidental; they are part of what a jurisdiction is selling alongside its labour costs and tax incentives.

2. Cambodia’s Accounting and Auditing Architecture Today
2.1 A single, purpose-built regulator

Cambodia consolidated oversight of the profession under the Accounting and Auditing Regulator (ACAR), established under the Ministry of Economy and Finance and operating under the Non-Bank Financial Services Authority. ACAR issues three categories of professional licence — Level 1 accounting (bookkeeping only), Level 2 accounting (bookkeeping and financial statement preparation), and auditing — and has paired licensing with a functioning Quality Assurance Review programme aligned with international standard-setting body requirements. This gives Cambodia something several regional peers built only gradually: a single door through which both standards and enforcement pass.

2.2 Full IFRS adoption, without local carve-outs

ACAR has adopted IFRS Accounting Standards without modification as the basis for Cambodian financial reporting for publicly accountable entities, alongside a separate framework for not-for-profit entities. For investors, unmodified adoption removes a layer of reconciliation risk that persists in jurisdictions running a nationally adapted variant of IFRS or a parallel local GAAP. Statutory records must still be kept in Khmer and in Khmer riel, with dual-language or foreign-currency reporting permitted only under conditions approved by the Ministry of Economy and Finance — a practical friction point for multinational groups consolidating into other currencies, but not a substantive divergence in accounting treatment.

2.3 A maturing profession, still building scale

Cambodia’s own CPA qualification became operational with its first sittings in 2024, complemented by an Accounting Technician Qualification developed with UNDP and ICAEW support. As of March 2026, ACAR’s public register showed 131 licensed firms: 8 with a Level 1 accounting licence, 61 with Level 2, and 62 with an auditing licence. That is a functioning market, but a narrow one relative to the pipeline of new investment entities it is being asked to serve — and it means due diligence on audit-firm capacity, not just audit-opinion quality, is now a genuine part of investor screening.

2.4 Tightening professional accountability

ACAR has moved in parallel to raise the entry and ongoing-conduct bar for licensees, introducing stricter “fit and proper” vetting criteria for individuals and firms applying for or renewing licences, together with mandatory reporting obligations when personnel face issues of dishonesty, fraud, or insolvency. For investors, this signals a regulator willing to police its own licensed population rather than treat licensing as a one-off administrative step — a meaningful, if still young, credibility signal.

3. Comparative Positioning Across ASEAN, 2026

No jurisdiction in the region combines every advantage. The comparison below sets out how Cambodia’s accounting and auditing environment stacks up against the ASEAN peers most frequently cited by investors weighing a “China+1” or regional-diversification allocation.

Market	Reporting standards	Regulatory structure	Audit market depth	Investor-facing friction
Cambodia	IFRS adopted without modification	Single regulator (ACAR) + KICPAA	~131 licensed firms; thin outside Phnom Penh	Statutory books in Khmer/KHR; talent bench still shallow
Vietnam	VAS, converging toward IFRS by policy roadmap	Ministry of Finance oversight; VACPA	Larger domestic market; strong mid-tier firm base	VAS-to-IFRS reconciliation still commonly needed
Thailand	TFRS, substantially IFRS-aligned	Federation of Accounting Professions	Deep, long-established profession	Foreign audit-firm ownership restrictions
Indonesia	PSAK, converged but not identical to IFRS	IAI standard-setter; OJK for listed entities	Large but fragmented market	Local-language filings; residual PSAK–IFRS gaps
Philippines	PFRS, fully IFRS-aligned	SEC / BOA oversight	Established Big Four and mid-tier presence	Relatively mature; fewer structural gaps
Singapore	SFRS(I), full IFRS adoption	ACRA single regulator	Deep, internationally networked	Benchmark market; higher cost base

Two things stand out. First, Cambodia’s decision to adopt IFRS without local modification puts it in the same camp as Singapore and the Philippines on pure standards alignment — ahead of Vietnam and Indonesia, which still carry converging or partially converged national frameworks. Second, Cambodia’s regulatory architecture is comparatively young and its market comparatively thin: a single-digit number of internationally networked firms serve a rapidly growing pool of foreign-invested entities, which is the opposite problem to Thailand or Singapore, where the constraint is cost rather than capacity.

4. Where Cambodia’s Comparative Advantage Is Real

• Standards credibility without a convergence timeline. Because IFRS was adopted wholesale rather than nationally adapted, Cambodia does not carry the multi-year “convergence roadmap” overhang that complicates investor due diligence in Vietnam and Indonesia.
• A single point of regulatory contact. ACAR’s consolidation of licensing, standard-setting liaison, and quality-assurance review under one body is simpler for investors to navigate than jurisdictions splitting these functions across several agencies.
• Open foreign participation. The 2021 Law on Investment permits full foreign ownership for most Qualified Investment Projects, with no general local-equity requirement — a more liberal starting position than Thailand’s Foreign Business Act restrictions on many service activities, audit firms included.
• A young profession scaling from a low base. Cambodia’s CPA and Accounting Technician programmes are recent enough to be built with international curricula and technical assistance (ICAEW, UNDP) baked in from the start, rather than retrofitted onto an older national qualification.
• Digital and procedural modernisation moving in the same direction as licensing reform, including the rollout of e-invoicing and continued digitisation of ACAR’s licensing and filing functions, both of which reduce the manual-compliance burden that has historically been a complaint among foreign investors.

5. Where the Advantage Is Still Fragile

• Market depth. A licensed population of roughly 131 firms, most without international network affiliation, means capacity can become a genuine constraint if investment approvals continue at the pace seen through 2025–2026, when several hundred projects a year already strain available qualified audit hours during peak filing season.
• Talent pipeline lag. A CPA qualification with its first cohorts only sitting exams in 2024 will not, by itself, produce the depth of experienced partners and technical staff that investors associate with more established regional practices for several more years.
• Compliance-cost complexity beyond the headline rate. As Cambodia’s own tax-competitiveness analysis has noted, investors increasingly weigh total compliance burden — accounting, audit, documentation, and dispute-resolution costs — rather than the statutory tax or audit-fee rate alone; transfer-pricing documentation under Prakas 574 and evolving e-invoicing obligations both add to that burden even as they professionalise the system.
• Institutional consistency. Cambodia’s own investment-guides literature continues to flag institutional capacity and regulatory consistency as structural challenges alongside an otherwise positive trend, a caveat that applies as much to audit and tax administration as to investment licensing generally.
• Language and currency friction. Statutory bookkeeping in Khmer and Khmer riel, with only conditional allowance for dual-language or foreign-currency records, adds a translation and consolidation step that peers with English or bilingual statutory filing regimes do not impose.

6. Strategic Implications, 2026–2031
6.1 For the regulator and profession

The single highest-leverage action available to ACAR and KICPAA over the next five years is widening the licensed, internationally credible audit-firm base outside Phnom Penh, in step with where new Qualified Investment Projects and Special Economic Zone activity are concentrated — Sihanoukville, Svay Rieng, Kampong Speu, and similar corridors. Sustained investment in the CPA and Accounting Technician pipelines, and continued alignment with International Standards on Quality Management, will determine whether audit quality keeps pace with audit volume rather than being diluted by it.

6.2 For accounting and audit firms

Firms that can combine local ACAR/KICPAA licensing with an international network affiliation, sector specialisation in the industries actually attracting capital — electronics, agro-processing, logistics, renewable energy — and bilingual (Khmer/English) service delivery are positioned to capture a disproportionate share of a growing but still-concentrated market. Early investment in transfer-pricing, e-invoicing, and ISA 705-compliant audit-opinion capability is likely to be a differentiator rather than a mere compliance cost over this horizon.

6.3 For foreign investors

Due diligence on Cambodia should now explicitly include audit-firm capacity and continuity, not only the headline fact of IFRS adoption. Investors entering higher-value manufacturing, financial services, or technology sectors should budget for the compliance-cost realities of transfer-pricing documentation, e-invoicing integration, and Khmer-language statutory bookkeeping from the outset, and treat the choice of local audit and accounting partner as a strategic relationship rather than a commoditised annual filing exercise.

Outlook: 2026–2031

Cambodia’s accounting and auditing framework is better positioned on paper than its market depth currently allows it to fully deliver — a gap that is narrowing but has not closed. If ACAR and KICPAA succeed in scaling licensed capacity and CPA output in step with investment approvals, and if firms continue building sector and cross-border capability, accounting and auditing quality could genuinely function as a differentiator for Cambodia within ASEAN by the end of this horizon, rather than simply keeping pace with the compliance expectations of the investors it is trying to attract. The more likely near-term path is incremental convergence: a steadily improving but still comparatively young profession, whose credibility will be tested most directly during the next cycle of large-scale FDI due diligence.
