Scope of the documentation obligation

Under the transfer pricing regulations in Prakas 574, effective from 1 January 2025, a taxpayer with related-party transactions must prepare documentation unless it qualifies for the small-taxpayer exemption. That exemption applies where, during the year, the taxpayer has annual turnover of less than approximately KHR 8 billion and tangible assets of less than approximately KHR 4 billion, together with the related condition on its transactions. A related-party disclosure annex is filed with the corporate income tax return, which is due within 90 days of the fiscal year-end.

Distinctive features of the Cambodian regime

The defining feature of the Cambodian regime is its recency: the documentation framework under Prakas 574 applies only from 2025, so it represents a newly formalised obligation rather than a long-standing one, structured around a small-taxpayer safe harbour defined by turnover and assets. The enforcement runs through the audit rather than a fixed documentation fine. Where no documentation is available it is difficult to justify the pricing of related-party transactions, exposing the taxpayer to a transfer pricing adjustment, and an obstruction penalty can apply where requested documents are not submitted. There is no Country-by-Country reporting obligation in the regime as captured.

Benchmarking and comparables

Local comparables are preferred, but they are difficult to find given the limited publicly available data and the small number of locally listed companies, so regional comparables are accepted. There is no stated preference between single-year and multi-year testing, and a roll-forward study is acceptable. The general limitation period is three years, extendable to ten years where fraud or obstruction is involved, with audits generally covering the previous three unaudited years.
