Cambodia VAT Guide 2026

Cambodia VAT at a glance

Do I need to comply? — 60-second check

Do you have to apply for registration for Cambodia VAT? The answer turns on three triggers — and one of them is particularly easy to miss for overseas digital service providers who assumed they could operate informally in the Cambodian market. The first trigger is the resident-business test: Medium Taxpayers (annual turnover KHR 700M–4B) and Large Taxpayers (above KHR 4B) must register for VAT; Small Taxpayers may operate outside. The second is the non-resident e-commerce trigger: under Sub-Decree 65 (effective 8 April 2022), overseas companies supplying digital products and services to Cambodian customers must apply for VAT registration under the simplified framework. The third is the imported-services trigger for B2B: Cambodian VAT-registered businesses self-assess VAT on imported services under reverse charge.

Before you dig into the persona tracks, run through this short check. It tells you which of the four tracks below applies to you — and which you can skip:

• Cambodian-resident business? Whether you must apply for registration depends on your taxpayer classification — Medium Taxpayer or Large Taxpayer status triggers VAT registration. The Local Cambodian Business track covers the full picture.
• Overseas company supplying digital services or SaaS to Cambodian customers? Foreign SaaS / Digital Services Seller track. Sub-Decree 65 (2022) introduced mandatory VAT registration for non-resident e-commerce / digital service providers. Quarterly returns through GDT online services.
• Overseas company shipping physical goods to Cambodian consumers — your own store, marketplace-routed? Foreign E-commerce Seller track. Import VAT at 10% applies at customs alongside Customs Duty and Special Tax (for specific categories).
• Overseas company importing goods into Cambodia for distribution, manufacturing, or onward sale? Foreign Importer track. Import VAT at 10% applies at customs on CIF + duty + applicable Special Tax base. Recoverability through input VAT credit for VAT-registered Cambodian entities. SEZ (Special Economic Zone) framework provides preferential treatment for qualifying export-oriented operations.

Two contextual points worth surfacing up front. First: Cambodia’s economy operates with widespread USD usage alongside the Cambodian Riel — VAT obligations are denominated and reported in KHR, but underlying commercial transactions often denominate in USD. This dual-currency reality creates operational complexity around exchange rate selection and VAT calculation. Second: Sub-Decree 65 on E-commerce VAT (2022) was a meaningful structural addition — overseas digital service providers historically operated informally in the Cambodian market; the post-2022 framework formalises this with simplified registration through GDT online services.

Foreign SaaS / Digital Services Seller into Cambodia

You’re an overseas company supplying digital services to Cambodian customers and you have no Cambodian permanent establishment. The first question isn’t “do I have to apply for registration” — it’s “does Sub-Decree 65 on E-commerce VAT (effective 8 April 2022) apply to your specific service category”. The post-2022 framework requires non-resident vendors supplying digital products and services to Cambodian customers to register under the simplified framework, charge 10% VAT on B2C supplies, and submit quarterly returns through GDT online services. The B2B portion typically operates under reverse charge with the Cambodian VAT-registered buyer self-assessing.

Are your Cambodian sales actually in Cambodia’s tax base?

Place of supply for cross-border digital services follows the recipient’s location. Sub-Decree 65 and GDT guidance set out indicators expected for the determination: customer billing address in Cambodia, payment instrument issued by a Cambodian institution, IP address resolving to Cambodia, and other commercially relevant location data.

Take Manolete Lumiere SAS, a French entertainment SaaS with EUR 5 million ARR. Manolete operates a streaming-and-content platform sold as B2C subscriptions globally; the Cambodian subscriber base reached USD 280,000 of annual revenue in 2025. Under Sub-Decree 65, Manolete is required to register with GDT, charge 10% VAT on Cambodian B2C subscriptions, and submit quarterly returns. The dual-currency reality (Manolete’s subscribers pay in USD; VAT must be denominated in KHR for reporting) creates an exchange-rate calculation discipline.

The triggers — and the timing window each opens

Three operational triggers.

The Sub-Decree 65 trigger applies on every cross-border digital service supply to a Cambodian customer. Registration is required for non-resident vendors of e-commerce / digital services regardless of revenue threshold; the framework operates on a category-based rather than threshold-based trigger.

The reverse-charge B2B trigger applies for imported services to Cambodian VAT-registered businesses. The Cambodian buyer self-assesses VAT on its own monthly return; the non-resident supplier does not directly charge VAT under this mechanism.

The permanent-establishment trigger applies when an overseas company creates a Cambodian presence. The Cambodian presence has direct registration obligations under the standard VAT framework.

What the registration actually involves

Registration runs through GDT’s online services portal for non-resident e-commerce suppliers. Four operational steps:

• Apply for non-resident e-commerce VAT registration through GDT. Required information includes business name and home jurisdiction details, authorised representative information, business activity description, and Cambodian revenue data.
• Receive the Tax Identification Number assigned by GDT. The TIN appears on every invoice issued to Cambodian customers.
• Designate a Cambodian tax representative — commonly engaged for compliance support given the framework’s relative novelty and operational complexity.
• Configure billing platform for Cambodia 10% VAT on B2C supplies to Cambodian customers, with the TIN displayed on invoices, and KHR-denominated VAT calculation.

What you charge, and on what

Cambodian VAT at 10% applies to B2C e-commerce / digital service supplies under Sub-Decree 65.

For B2B supplies to Cambodian VAT-registered business buyers, the reverse-charge mechanism applies — the Cambodian buyer self-assesses on its monthly return.

Consider BrightLearn Inc. selling USD 79/month subscriptions. A Phnom Penh consumer subscribes. BrightLearn charges USD 79 + 10% VAT = USD 86.90, collects the KHR equivalent of USD 7.90, and submits this through the quarterly return.

What a Cambodian tax invoice must say

Mandatory elements: supplier name and TIN, customer identification (name or email for B2C), invoice date, description of services, total amount, VAT amount (10%) separately stated, KHR equivalent of VAT amount (with exchange rate source).

Submitting and paying GDT

Non-resident e-commerce VAT registrants submit quarterly returns through GDT online services. Returns and payment due by the 20th day of the month following each calendar quarter.

What this actually costs

Approximate operating ranges for a non-resident e-commerce VAT registrant:

• Cambodian tax representative retainer (commonly engaged): USD 6,000–18,000 per year.
• Quarterly return preparation: USD 1,000–3,000 per submission — typically bundled into representative retainer.
• Initial registration through GDT online: minor cost; mostly internal effort plus representative onboarding.
• Initial billing-platform configuration for Cambodia 10% VAT and KHR-denomination handling: USD 3,000–10,000.
• Annual reasonableness review by Cambodian tax advisor: USD 2,000–6,000 per year.

The patterns that catch foreign SaaS sellers out

After enough overseas-seller engagements, three patterns recur.

The first: misjudging the post-2022 framework. Sub-Decree 65 fundamentally changed Cambodia’s cross-border digital service VAT landscape; vendors operating under pre-2022 assumptions face compliance gaps.

The second: under-investing in dual-currency operational discipline. KHR-denominated VAT reporting on USD-denominated commercial transactions requires consistent exchange rate methodology.

The third: under-investing in indicator capture for customer location. GDT’s audit attention on cross-border digital services has progressively intensified post-Sub-Decree-65.

If you get this wrong

Fine framework under the Law on Taxation and Sub-Decree 65:

• Late submission: KHR 100,000 per month of delay + interest.
• Late payment: 2% per month interest.
• Under-reporting: 10–40% of underpaid tax depending on circumstances.
• Tax evasion: multiple of evaded tax + criminal prosecution under Law on Taxation.

If you’ve been operating without proper compliance

Engage a Cambodian tax advisor with cross-border digital services experience. Voluntary disclosure prior to GDT audit unlocks fine mitigation. Sub-Decree 65 has been operational since 2022; GDT’s enforcement posture has progressively matured.

Foreign E-commerce Seller into Cambodia

Do you have to comply with Cambodia’s import VAT framework? The answer is yes the moment your goods physically enter Cambodian customs territory. The General Department of Customs and Excise applies VAT at 10% on CIF + Customs Duty + applicable Special Tax at clearance. Cambodia’s e-commerce sector has been growing rapidly, with marketplaces like Khmer24, MD Mall, and various social-commerce platforms operating alongside cross-border platforms shipping to Cambodian consumers.

Does this apply to your store?

If physical goods you sell arrive at a Cambodian address, you’re inside the import-VAT framework:

• Direct cross-border shipping: import VAT at 10% on CIF + Customs Duty + applicable Special Tax. Cambodia has relatively standard de minimis thresholds; most commercial e-commerce consignments attract import VAT.
• Cambodian fulfilment via distributor or own subsidiary: imported under subsidiary’s name; full VAT + duty paid at customs; domestic VAT on onward sales.
• Marketplace-routed sales: Cambodia’s e-commerce marketplace landscape includes Khmer24 and others. Per-marketplace confirmation in writing.

The triggers — and the timing window each opens

Import VAT attaches at every consignment. Registration question is structural: Cambodian subsidiary (registers based on taxpayer classification — Medium or Large) vs Cambodian distributor.

What the registration involves (for Cambodian subsidiaries)

Cambodian subsidiary route: incorporation under the Law on Commercial Enterprises → Ministry of Commerce registration → Tax Identification Number from GDT → VAT registration (based on taxpayer classification) → Customs registration → bank account configurations. For foreign-invested entities, additional Council for the Development of Cambodia (CDC) registration may apply. Full sequence typically 6–10 weeks.

Charging VAT on goods, shipping, and returns

Cambodian subsidiary as VAT-registered: 10% on most taxable goods. Zero-rated for exports and SEZ supplies.

On import: 10% VAT on CIF + Customs Duty + applicable Special Tax. Customs Duty varies by HS code. Special Tax applies to specific categories (luxury items, certain consumer goods).

Invoice rules for e-commerce

Cambodian VAT invoice format applies for VAT-registered entities. GDT’s electronic invoicing infrastructure is progressively expanding.

Submitting — and the marketplace question

Cambodian subsidiary submits monthly VAT returns by the 20th of the following month through GDT online services.

Cambodian marketplace operational treatment varies; confirm in writing per marketplace.

The compliance cost stack

Total run-rate for mid-volume foreign e-commerce through Cambodian subsidiary typically lands in USD 15,000–60,000 per year. Subsidiary establishment one-time USD 5,000–20,000.

The patterns that catch e-commerce sellers out

The first: under-preparing for the dual-currency operational complexity that pervades Cambodia’s commercial environment.

The second: under-investing in CDC and Ministry of Commerce registration coordination for foreign-invested entities.

The third: under-monitoring of Sub-Decree 65 expansion to broader categories beyond initial digital service scope.

The fine exposure

Same framework: KHR 100,000 per month of delay for late submission, 2% per month late-payment interest, 10–40% under-reporting fine, criminal exposure for fraud.

If you’ve been selling without proper structure

Engage a Cambodian tax advisor with cross-border experience. Voluntary disclosure prior to GDT audit unlocks fine mitigation.

Foreign Importer / Physical Goods Seller into Cambodia

Do you have to deal with Cambodia’s import tax framework? Yes for every commercial-scale import. The General Department of Customs and Excise (GDCE) applies Customs Duty (HS-code dependent), VAT at 10%, Special Tax (for specific categories like luxury items, alcohol, tobacco, motor vehicles, certain petroleum products), and Public Lighting Tax (where applicable). The Council for the Development of Cambodia (CDC) and the SEZ framework provide structural preferential treatment for qualifying export-oriented operations.

Whether you’re the importer of record

Bring goods into Cambodia and GDCE assesses Customs Duty, VAT at 10%, applicable Special Tax, Public Lighting Tax (where applicable), and any sector-specific levies. Combined liability payable at clearance — unless SEZ or bonded arrangement defers it.

The triggers — and the timing window each opens

Import VAT attaches at every consignment. Registration question is structural based on Cambodian subsidiary vs distributor.

What the registration involves (customs and VAT together)

Three importer-specific registrations:

• Customs registration with GDCE.
• CDC registration for foreign-invested entities and SEZ tenant approval where applicable.
• Importer-of-record designation through GDCE.

How import VAT is calculated

Standard 10% VAT on CIF + Customs Duty + applicable Special Tax. For most consumer goods: USD 100K CIF → USD 15K Duty (15%) → USD 115K VAT base → USD 11.5K VAT. Special Tax adds to base for luxury / specific categories.

Invoicing for re-sold imports

Cambodian VAT invoice format applies. Reference the customs declaration number on the tax invoice.

Submitting and where importers extract real value

Cambodian subsidiary submits monthly VAT returns through GDT online services. Input VAT recovery is the principal compliance value at the 10% rate.

The real cost of compliance for importers

Itemised cost matrix for mid-sized foreign importer through Cambodian subsidiary (USD 5M–USD 50M annual Cambodian turnover):

What we see importers get wrong

Four lines we audit:

• ☐  HS classification correct and defensible — GDCE scrutiny is active.
• ☐  Input VAT reconciliation discipline — customs records vs monthly VAT return.
• ☐  Customs declaration reference on outward tax invoices.
• ☐  SEZ documentation chain in place where preferential treatment is claimed.

Customs and VAT fines together

GDT fine framework plus Customs Law fines for misdeclaration.

If you’ve been importing without proper structure

Engage both a Cambodian customs broker AND a Cambodian tax advisor before voluntary disclosure.

Local Cambodian Business

Do you have to apply for registration as a Cambodian business? The answer depends on your taxpayer classification: Medium Taxpayer (annual turnover KHR 700M–4B) and Large Taxpayer (above KHR 4B) status triggers mandatory VAT registration; Small Taxpayer (KHR 250M–700M) status places you outside the standard VAT regime. The bigger 2026 questions for Cambodian-resident businesses are about continued GDT modernisation through e-VAT and e-Tax infrastructure expansion, and the operational discipline around the dual-currency commercial environment.

When the trigger level kicks in

Medium Taxpayer (KHR 700M–4B annual turnover) and Large Taxpayer (above KHR 4B) classifications trigger VAT registration. Small Taxpayer status (KHR 250M–700M) places businesses outside the standard VAT regime.

Acting in time and what backdating means

Within 30 days of becoming subject to the relevant taxpayer classification.

Registering as a resident Cambodian business

Through GDT online services. Documents required: Ministry of Commerce business registration, TIN, proof of business address, bank account details, authorised representative designation.

What you charge — and the zero-rated vs exempt distinction

Standard rate 10%. Zero-rated 0% on exports and qualifying SEZ supplies — input VAT credit recoverable. Exempt categories (unprocessed agricultural products, certain healthcare and educational services) — outside VAT system.

Invoicing rules and electronic infrastructure

Cambodian VAT invoice format. GDT’s e-VAT and e-Tax infrastructure is progressively expanding.

Submitting rhythm for local businesses

Monthly VAT returns through GDT online services by the 20th of the following month.

The internal cost of being VAT-compliant

Medium-sized businesses (USD 1M+ revenue): USD 8,000–30,000 per year on external Cambodian tax advisor support.

The traps for local Cambodian businesses

Where do most local Cambodian finance teams trip up first in 2026?

Mis-managing the dual-currency operational reality. USD-denominated commercial transactions with KHR-denominated VAT reporting requires consistent exchange rate methodology and documentation.

What’s the second?

Under-investing in GDT electronic infrastructure adoption as e-VAT and e-Tax progressively expand.

And the third?

Misjudging the Small/Medium/Large Taxpayer classification transitions as turnover crosses thresholds. The classification change triggers new compliance obligations.

Fine exposure for residents

Same framework: KHR 100,000 per month of delay for late submission, 2% per month late-payment interest, 10–40% under-reporting fine.

Catching up after a misclassification

Voluntary disclosure prior to GDT audit unlocks fine mitigation.
