Cambodia Property Capital Gains Tax Guide: 2027 Rules
Cambodia property capital gains tax from January 2027: who pays, rates, timing vs stamp duty 2026 window, seller behaviour, and foreign owner planning.
Quick answer: Cambodia property capital gains tax is scheduled from 1 January 2027 while stamp duty incentives run through 31 December 2026. Foreign owners should model buy, hold, and sell timing with a qualified tax adviser before late-2026 transactions.
When does Cambodian property capital gains tax start?
Capital gains tax on immovable property takes effect on 1 January 2027 at 20% of the gain, and it applies to non-residents on Cambodian assets. The charge has been legislated and repeatedly deferred, so the operative fact for a buyer is the current effective date rather than the drafting history.
| Item | Position |
|---|---|
| Effective date | 1 January 2027 |
| Rate | 20% of the gain |
| Applies to non-residents | Yes, on Cambodian immovable property |
| Basis | The gain, not the sale price |
| Interaction with transfer tax | Separate; the 4% transfer tax is unaffected |
| Prior deferrals | Several; treat the date as live but verify before relying |
Our underwriting models every exit after 1 January 2027 on the assumption the charge applies, because planning for it and being wrong costs nothing while the reverse is expensive. The buyer scenario that suffers is the short-hold purchaser who bought in 2025 expecting to sell in 2028 and never priced a 20% charge on the gain into the model.
- Model the charge as live for any exit after 1 January 2027.
- It is charged on the gain, not on the price.
- Full fee context sits in the taxes and fees guide.
- Exit routes are in the exit strategy guide.
- Relief before the date is in the stamp duty guide.
Who does it actually affect?
Anyone selling Cambodian immovable property at a gain after the effective date, including non-residents. Whether it hurts depends almost entirely on holding period and the size of the gain rather than on the buyer’s nationality or structure.
| Owner | Exposure |
|---|---|
| Short-hold buyer selling in 2027 or 2028 | High; the gain is concentrated in a few years |
| Long-hold owner selling after a decade | Present, but spread across a long period |
| Owner selling at no gain | None on this charge; other costs still apply |
| Owner holding and letting indefinitely | None until sale |
| Heir receiving the unit | Depends on treatment; take advice |
| Owner selling before 1 January 2027 | Outside the charge, if registration completes |
Our analysis treats the last row carefully, because completing before the date means the transfer registering before it, whatever date the contract was signed, and registration on a hard, LMAP or strata title takes about 12 weeks. A seller aiming to complete outside the charge needed to be in the process well before the end of 2026, and a seller starting in November 2026 was already too late.
- Completion means registration, not signature. Allow about 12 weeks.
- Holding period matters more than nationality or structure.
- Transfer timing sits in the transfer timeline guide.
- Resale timing is in the resale valuation guide.
- Inheritance treatment is in the inheritance guide.
How does it interact with the 2026 stamp duty window?
The two run in opposite directions and bracket the same decision. Stamp duty relief through 31 December 2026 lowers the cost of buying; capital gains tax from 1 January 2027 raises the cost of selling, and both bind to registration rather than to contract dates.
| Date | Effect | Side of the trade |
|---|---|---|
| Through 31 Dec 2026 | Relief on qualifying value | Buyer |
| From 1 Jan 2027 | 20% of the gain | Seller |
| Both bind to | Registration at the cadastre | Both |
| Transfer duration | About 12 weeks | Both |
| Net effect on a short flip | Worse after the date | Seller |
| Net effect on a long hold | Marginal | Both |
Our underwriting reads the pair as a mild encouragement to buy in 2026 and a strong discouragement from flipping after 2027, which is broadly what the policy appears designed to produce. The red flag is a sales pitch that quotes the relief without mentioning the charge, since a buyer who captures a few thousand dollars of relief and then pays 20% of a gain three years later has been sold half a picture.
- One lowers the cost of buying, the other raises the cost of selling.
- A pitch quoting only the relief is quoting half the arithmetic.
- Relief detail sits in the stamp duty guide.
- The cost picture is in the closing costs guide.
- Yield after tax is in the net versus gross yield guide.
What can a foreign owner actually do about it?
Five things, and none of them is avoidance. The charge is on the gain, so the levers available are the size of the gain, the timing of the sale, and the quality of the records that establish the base cost.
| Lever | How it works |
|---|---|
| Document the base cost properly | Purchase price, transfer tax, legal fees, capital improvements |
| Keep improvement receipts | Unevidenced spend is hard to add to the base |
| Extend the holding period | Spreads the gain and reduces the pressure to sell |
| Complete registration before the date, if genuinely possible | Requires about 12 weeks of lead time |
| Take advice where a structure holds the asset | Treatment differs and multiplies filings |
| Model the charge into your entry price | Changes what you are willing to pay today |
Our underwriting treats the first two rows as the highest-value work, because the base cost is what the charge is measured against and it is assembled at purchase rather than at sale. An owner with a complete file of purchase costs and improvement receipts pays tax on a smaller gain than an owner with the same economics and no paperwork. The work involved is ordinary record-keeping, and it costs nothing.
- The base cost file is built at purchase.
- Unevidenced improvement spend is spend you cannot deduct.
- Cost lines sit in the closing costs guide.
- Furnishing and improvement is in the furnishing guide.
- Exit routes are in the exit strategy guide.
Buying or selling across the 2027 boundary? We will model both sides before you agree a completion date.
Model both sidesBuyer scenarios
Scenario A: Buy in 2026 for rental hold, where CGT matters only on eventual sale after 2027.
Scenario B: Flip within 24 months, where CGT plus thin resale liquidity can erase brochure yield.

Risks, red flags, and what to verify
- Treating the start date as flexible: the regime applies to disposals from 1 January 2027 and completion date is what counts.
- No acquisition records kept: the gain is computed against your cost base, and undocumented costs cannot be deducted.
- Improvement spending undocumented: invoices and transfers are what make a renovation deductible rather than invisible.
- Selling into a crowded window: if many owners exit before the start date, pricing in late 2026 reflects that crowd of sellers more than anything about your own unit.
- Home-country treatment unmodelled: the same gain may be taxed again where you are resident, with or without relief.
Advantages and disadvantages
| Advantages | Disadvantages |
|---|---|
| USD-priced Phnom Penh stock | 76,000 to 80,000 units caps rent growth |
| 2026 stamp duty window | capital gains tax on property from 1 January 2027 changes exit math |
| Strata path for condos | Quota bottlenecks on popular towers |
| ASEAN growth narrative | Thinner liquidity than Thailand |
| Payment plans on entry tier | 8.9% banking NPL ratio completion risk |
| Growing expat tenant base | Legal paths vary by product type |
How did the market behave approaching the date?
Deferral history matters here, because the charge has been announced and postponed more than once and the market has learned to discount announcements. That produces two opposite behaviours near an effective date, and a buyer meets both.
| Behaviour | What it looks like |
|---|---|
| Accelerated selling | Owners listing to complete before the date |
| Discounting to force completion | Price cuts tied to a registration deadline |
| Wait-and-see | Owners assuming another deferral |
| Buyers using the deadline as leverage | Offers conditional on completing in time |
| Agents quoting urgency without arithmetic | The most common, and the least useful |
| No behaviour change at all | Long-hold owners, correctly |
Our analysis treats deadline-driven discounting as genuinely interesting and deadline-driven urgency as noise. A seller offering a real price reduction to complete before the date is transferring value to the buyer; an agent describing urgency without a number is transferring nothing. The checklist item is to ask what the discount actually is in dollars, and to check that the registration timetable can realistically be met.
- A real deadline discount has a number. Urgency without one does not.
- Check the registration timetable before accepting a deadline-driven price.
- Valuation method sits in the resale valuation guide.
- Market context is in the 2026 outlook.
- Transfer timing is in the transfer timeline guide.
How should a landlord plan around it?
A landlord letting for income is exposed to the charge only on sale, so the planning question is whether the exit assumption in their model still holds. A unit yielding 5.22% to 7.4% gross does not become a bad asset because of a charge that applies once.
| Landlord position | What changes |
|---|---|
| Holding indefinitely for income | Nothing until sale |
| Planning a sale in 2027 or 2028 | The gain is now taxed at 20% |
| Modelling total return with a five-year exit | Reduce the terminal value accordingly |
| Considering a sale to fund another purchase | The charge is a real drag on rotation |
| Passing the asset to heirs | Different treatment; take advice |
| Selling at a loss or flat | The charge does not arise |
Our underwriting reprices rotation rather than ownership. Moving capital between Cambodian units becomes materially more expensive once each sale triggers 20% of the gain plus 3% to 5% agency and legal fees, which argues for fewer and better purchases rather than an active portfolio. The buyer scenario worth revisiting is the investor planning to trade up every three years, because that plan was built for a market without this charge.
- The charge reprices rotation.
- Fewer, better purchases beat an active trading plan under this regime.
- Yield workings sit in the yield guide.
- Rental tax is in the rental income tax guide.
- Inheritance is in the inheritance guide.
What to decide before the date arrives
Archive SPA, quota letters, and tax receipts in one shared folder before your first tenant or instalment milestone.
Compare shortlist rows against Cambodia Property Investment Guide 2026 and Phnom Penh Rental Yield Guide before you increase deposit beyond 10% to 20%. Request written foreign quota confirmation, milestone photos on off-plan towers, and sinking fund statements on resale stock. Model net yield after management and vacancy, and set brochure gross claims aside. Archive every SPA revision and bank SWIFT receipt in one folder for tax and exit planning.

What should a buyer do differently today?
Three things, all of them at purchase rather than at sale. The charge applies once, on the gain, and the levers that matter are set long before an owner thinks about selling.
| Action now | Effect later |
|---|---|
| Open a base-cost file at purchase | Price, 4% transfer tax, legal fees, improvements |
| Keep every improvement receipt | Unevidenced spend cannot be added to the base |
| Assume a longer hold in your model | Spreads the gain and removes forced-sale pressure |
| Price the charge into what you offer | Changes the maximum sensible bid today |
| Avoid planning a three-year rotation | Each rotation now costs 20% of the gain |
| Take advice if a structure holds the asset | Treatment and filings differ |
Our underwriting has moved from modelling five-year holds to modelling seven- and ten-year holds on Cambodian residential since this charge became imminent, because the arithmetic of a short flip no longer works once 20% of the gain, 3% to 5% agency and legal fees are all deducted from a market absorbing 3% to 4% of stock a year. That is a change in strategy rather than a change in whether the market is worth entering.
- The base-cost file is built at purchase, and it is free to keep.
- The charge reprices short holds; the case for the market itself is unchanged.
- Cost lines sit in the closing costs guide.
- Exit routes are in the exit strategy guide.
- Market context is in the 2026 outlook.
