Taxation of Commercial Promotions in Cambodia: A Guide for Entrepreneurs

Any business registered in Cambodia that organizes commercial promotions (discounts, rebates, sweepstakes, gifts) is subject to the tax obligations described below. Expat entrepreneurs, especially those in Siem Reap, must ensure their accountant or tax department correctly applies the rules.

• VAT-registered businesses: must declare VAT on discounts and adjust their invoices.
• Businesses organizing sweepstakes: must withhold tax on winnings (cash or in-kind).
• Businesses offering gifts or samples: may be subject to VAT on the value of the item.
• Non-resident businesses: may have withholding tax obligations if they organize promotions through a local entity.

The tax rules for commercial promotions have been in effect for several years, but their enforcement is increasingly strict. Here are the key points to know.

To be tax compliant when organizing promotions, follow these steps.

1. Step 1: Identify the type of promotion. Discount, rebate, sweepstakes, gift, sample. Each type has different tax rules.
2. Step 2: Calculate VAT. For discounts, VAT applies to the net amount after discount. Ensure your invoices correctly reflect the reduction.
3. Step 3: Determine withholding tax. For sweepstakes, withhold 20% on the value of in-kind prizes (e.g., car, trip) and apply the progressive scale for cash winnings.
4. Step 4: Declare and pay taxes. Include VAT in your monthly declaration. Declare withholding tax within deadlines (usually the 15th of the following month).
5. Step 5: Keep a record of promotions. Retain lists of winners, prize values, modified invoices. These documents are required in case of an audit.
6. Step 6: Consult a tax expert. Cambodian rules can be complex. A local specialized accountant will help you avoid costly mistakes.

• Hotels and restaurants offering seasonal discounts must adjust their VAT declaration accordingly.
• Travel agencies organizing sweepstakes (e.g., free trip) must withhold 20% on the prize value and remit it to the tax authorities.
• Souvenir shops offering discounts must ensure their cash registers or billing software correctly handle VAT on the net amount.
• Expat entrepreneurs must train their accounting staff on the specific rules for promotions to avoid penalties during tax audits.
• Digital marketing companies managing promotional campaigns for clients must include tax obligations in their contracts.

Here are the most frequent mistakes made by expat entrepreneurs.

• Mistake 1 — Not declaring VAT on discounts. Some businesses apply the discount without adjusting VAT. However, VAT must be calculated on the net amount after discount.
• Mistake 2 — Forgetting withholding tax on in-kind prizes. During a sweepstakes, the value of the prize (e.g., a trip) is subject to a 20% withholding that the business must deduct and remit.
• Mistake 3 — Confusing discount and gift. A discount reduces the selling price, a gift is an item given for free. VAT rules differ: a gift may be considered a self-supply and generate VAT.
• Mistake 4 — Not keeping documentation. In case of an audit, the absence of a promotion register can lead to flat-rate penalties.
