Cambodia's Capital Gains Tax Arrives in 2027: The Property Owner's Planning Guide

For five years, Cambodia’s capital gains tax has been the regional oddity you could safely footnote: legislated in 2020, deferred, deferred again, never collected on a single condo. That era has an end date. From 1 January 2027, the 20% CGT applies to real estate — and this time the rest of the regime is already running around it, which changes how seriously to take the date. Twelve of our own articles reference this tax in passing; this is the deep-dive they point to. Citations are marked [S-NNN]; the source list is at the end.

How we got here — and why this deferral reads differently

The tax was born as Prakas 346 in 2020 and spent half a decade being postponed. Two things changed recently. First, in July 2025 the Ministry of Economy and Finance reissued the entire framework as Prakas 496, a fuller rulebook covering six classes of “capital assets” — immovable property, leases, investment assets like shares, goodwill, intellectual property, and foreign currency [S-150]. Second, in January 2026 the GDT’s Notification 041 deferred only the real-estate leg — to 1 January 2027 — while leaving the rest in force: gains on share transfers are taxable from 2026, catching M&A exits and shareholder reorganisations now [S-021].

Read those together and the signal is hard to miss. Cambodia did not park the tax; it built the machine, switched it on for everything else, and gave property owners one more year. Our standing advice across this site — model CGT on any exit after 2027 — is no longer conservatism; it is the schedule.

Who the tax catches

Prakas 496 reaches resident individuals on capital assets worldwide, and non-residents — individuals and entities — on assets located in Cambodia [S-150]. The typical reader of this site, a foreign owner of a Phnom Penh condo, is squarely in scope on sale. Three boundary cases worth knowing:

• VAT-registered (self-assessment) taxpayers — i.e., businesses — are taxed on gains under the ordinary Tax on Income instead [S-150].
• Non-residents’ gains taxed under CGT are exempted from the 14% withholding on Cambodian-sourced income, resolving a double-taxation worry from the earlier drafts [S-150].
• Trust-held property already lives under equivalent 20% treatment in the trust tax rules — see trust law for foreign owners [S-063].
• Residents of a double-tax-treaty partner apply the treaty’s capital gains article [S-150].

The math: two methods, one big documentation lesson

The rate is 20% of the gain — selling price minus deductions — and for immovable property you choose between two deduction methods [S-150]:

1. Lump-sum method: deduct a flat 80% of the sale price. The arithmetic collapses to 4% of gross proceeds, whatever your real gain.
2. Actual-expense method: deduct documented costs — what you paid, fees, qualifying expenses — under the Prakas’s substantiation rules.

Worked example, in the dollars Cambodian property actually trades in:

Scenario	Lump-sum	Actual expenses
Bought $150k, sell $200k	20% × ($200k − $160k) = $8,000	≈20% × ($200k − $150k − fees) ≈ $9,500
Bought $190k, sell $200k	$8,000	≈20% × ($200k − $190k) ≈ $2,000
Bought $220k, sell $200k (loss)	$8,000	$0 — but the loss is not refundable, nor usable against other gains [S-150]

The lesson sits in the bottom rows. The lump-sum method taxes your sale price, not your success — sellers with small gains, or none, pay 4% of gross unless they can prove their costs. In a mid-market that has corrected 15–20%, plenty of 2027-era sellers will be in exactly those rows. The cheapest tax planning available in Cambodia today is a folder: your SPA, your transfer-tax receipt, your renovation invoices.

The exemptions — narrow, but real

Article 6 of Prakas 496 exempts [S-150]:

• Your primary residence, held at least five years — strictly one residence per taxpayer and spouse combined. An owner-occupier expat who has lived in their condo since 2022 may exit clean in 2027; a landlord cannot.
• Transfers within relatives by succession, or by first-time donation (for establishing common property) — which dovetails with the estate mechanics in our inheritance guide and the family-property analysis in the spouse guide.
• Agricultural land owned by citizens and actively farmed, state and diplomatic property, and expropriations.

No holding-period taper, no indexation for inflation, no rollover into a replacement property — KPMG flags all three absences [S-150]. What you see is what you get: 20% of the gain or 4% of the price, unless an exemption fits.

The enforcement design: why this one will actually collect

Two provisions make the 2027 regime self-enforcing in a way the deferral years never required:

• An unpaid-CGT transfer is not legally valid (Article 15) [S-150] — the tax is welded to the title-transfer process itself, the same chokepoint that already collects the 4% transfer tax. There is no quiet route around it that ends with a registered title — and an unregistered “sale” is precisely the soft-title risk this site exists to warn about.
• The GDT can reassess your declared price against the stamp-duty base or the Property Evaluation Committee’s valuation [S-150] — the under-declared SPA, a regional folk tradition, becomes a tax-audit liability on top of everything else already wrong with it.

Filing is per-transaction: declare and pay within three months of realising the gain, at the GDT for Phnom Penh property or the provincial branch where the asset sits [S-150].

What it changes — and doesn’t — about the investment case

Be honest about the magnitude: for a documented seller with a healthy gain, the lump-sum method prices Cambodia’s exit at 4% of proceeds. Stack the round trip and Cambodia still undercuts the neighbourhood: the Philippines charges 6% of gross plus 1.5% stamp on every sale; Malaysia takes 30% of gains within five years and never drops below 10%; Singapore charges most foreigners 60% at the door. What 2027 actually ends is the zero — the era when yield math and exit plans could ignore the tax line entirely, and when “no CGT” could be waved around as if it were a permanent feature of a tax haven. It never was; it was a deferral, and the deferral now has a published expiry.

The pre-2027 checklist

• Assemble the cost file now — SPA, transfer-tax receipts, renovation invoices, agent fees. It is the difference between the $2,000 row and the $8,000 row above [S-150].
• Check the primary-residence clock — five years, one residence per couple [S-150]. If you are close to qualifying, the calendar matters.
• Model both methods before listing — and if you are selling at or near a loss, understand that only the actual-expense method respects that.
• Family transfers and estates: the relative-succession and first- donation exemptions [S-150] reward planning done before a sale is on the table — coordinate with your will and succession plan.
• Don’t structure around it — the validity rule [S-150] means the only exits that dodge the tax are the ones that never produce a registered title. That trade is worse than the tax.

The takeaway

Cambodia’s CGT spent so long deferred that the market priced it as folklore. Prakas 496 ended that: the regime is built, live for everything except real estate, and dated for property at 1 January 2027 — with collection welded to the title transfer and a default method that taxes gross proceeds at 4% when sellers can’t prove their costs. The response it demands is unglamorous: keep documents, know your exemption position, model the exit both ways, and update every yield and return calculation that still assumes zero. Cambodia remains the cheapest exit in its peer group even after 2027 — but “cheapest” and “free” were never the same claim. None of this is tax or legal advice; implementation details can shift again, so confirm the current position with a qualified Cambodian tax adviser before transacting.
