A buyer comparing Southeast Asian property markets will sometimes weigh up where each country sits on financial-information exchange. It is reasonable context to understand. It is also frequently over-weighted, because — as we explain throughout our CRS coverage — a country’s reporting status does not change your own duty to declare income to your home tax authority. With that caveat firmly in place, here is how Cambodia compares to its neighbours, drawn from the OECD’s own commitments list rather than the folklore that circulates on this topic. Citations are marked [S-NNN]; the source list is at the end.
The regional picture
The Common Reporting Standard has been adopted across most of the larger economies of the region — but the line runs in a less obvious place than commonly assumed. On the OECD’s official status list (updated May 2026), Singapore, Malaysia, Indonesia, and Brunei all began automatic exchanges by 2018, alongside the financial centres of Hong Kong, Japan, and China. Thailand is a recent joiner, undertaking first exchanges only by 2023 [S-064].
The widely repeated claim that “everyone but Cambodia, Laos, and Myanmar participates” is wrong in one important respect: Vietnam and the Philippines have not committed to automatic exchange either. Both appear — together with Cambodia — among the OECD’s 42 “developing countries not asked to commit and that have not yet set a date for the first year of exchanges” [S-064]; the OECD’s Asia Initiative names Cambodia, the Philippines, Uzbekistan, and Vietnam as its four Asian members in exactly this position [S-065]. Laos and Myanmar sit further out still: they do not appear on the commitments list at all, because they are not Global Forum members in the first place.
| Jurisdiction | Automatic exchange (CRS) | Since |
|---|---|---|
| Singapore | Yes | 2018 |
| Malaysia | Yes | 2018 |
| Indonesia | Yes | 2018 |
| Brunei | Yes | 2018 |
| Thailand | Yes | 2023 |
| Vietnam | No — no committed date | — |
| Philippines | No — no committed date | — |
| Cambodia | No — no committed date | — |
| Laos | Outside the framework entirely | — |
| Myanmar | Outside the framework entirely | — |

The common thread is still capacity: the OECD’s own reporting attributes the non-commitments to missing legal frameworks and insufficient administrative capacity, not to deliberate haven positioning [S-065]. But note what the corrected map does to the usual narrative — Vietnam, a far larger and faster-industrialising economy than Cambodia, sits in the same column. Non-participation is not a Cambodia oddity; it is where the region’s developing-country tier mostly still is.
One more distinction keeps Cambodia from being lumped with the true outsiders: it has been a Global Forum member since 2017 and exchanges tax information on request, a practice rated “Largely Compliant” in its 2026 peer review [S-066]. Laos and Myanmar offer no such channel. Treat the table as a snapshot, not a permanent state of affairs — the regional trend is clearly toward participation.
What the comparison actually tells you
The useful reading of this table is about financial-system maturity, not secrecy. A CRS-participating country like Singapore or Thailand has, almost by definition, a more developed tax administration, deeper integration with the international banking system, and smoother correspondent-banking relationships. A non-participating country like Cambodia has a younger system that is still building those capacities.
For a property investor, that maturity gap shows up in places that matter far more than reporting: the reliability of land registration, the depth and liquidity of the market, the ease of moving money in and out, and the strength of legal protections. These are the real differences between buying in Bangkok and buying in Phnom Penh — not whether a tax form crosses a border automatically.
The comparison that misleads
The unhelpful reading is the one that treats Cambodia’s non-participation as a reason to bank or buy there in order to stay out of sight. This is a mistake on two levels.
First, it is usually illegal. If you are tax-resident in a country that taxes worldwide income — which includes most of Europe, North America, Australia, and many others — you must declare your Cambodian income and assets regardless of what Cambodia reports. Using a non-CRS jurisdiction to conceal taxable income is evasion, not planning.
Second, it is a fragile basis for a long-term decision. Property is illiquid and held for years. Betting a structure on Cambodia remaining outside CRS is betting against the entire direction of international regulation. If Cambodia joins — and the regional trend suggests participation is more a question of when than whether — anyone who built a plan on non-reporting is left exposed.
The takeaway
The region splits three ways, not two: automatic exchangers (Singapore, Malaysia, Indonesia, Brunei, and since 2023 Thailand), Global Forum members without an automatic-exchange date (Cambodia, Vietnam, the Philippines), and countries outside the framework altogether (Laos, Myanmar) [S-064] [S-065]. Cambodia sits in the middle tier — no automatic reporting, but a functioning on-request exchange channel rated Largely Compliant [S-066]. That placement reflects how young its financial system is, not a deliberate posture. Understood properly, it is a lens on market maturity and the practical frictions of operating there — useful, sober context for a buyer weighing Cambodia against Thailand or Vietnam.
Understood improperly, as an invitation to hide money, it is both unlawful and unwise. Compare the region on the things that actually differ for an investor — title security, liquidity, capital mobility, legal recourse — and handle your tax affairs correctly wherever you are resident. That is the comparison worth making.
