Mr. Zhang runs an engineering company in Laos and recently paid a technical service fee to a design company in China. The finance officer Xiao Li asked: "Can we just wire the money directly?" Mr. Zhang recalled a friend mentioning that payments abroad might require withholding tax, but he was confused about the specifics.

In fact, Lao tax law has specific withholding tax (source deduction) rules for payments of service fees/charges, royalties, interest, dividends, etc. to overseas entities. Simply put, the payer must deduct a portion of the tax from the payment and remit it to the tax authority on behalf of the recipient.

When is withholding required?

According to the Income Tax Law and Tax Administration Law, enterprises are generally obligated to withhold tax when making the following payments to overseas entities:

Service fee/charge (e.g., consulting, design, management fees)
Royalty (e.g., patent, trademark, copyright royalties)
Interest (e.g., interest on loans from overseas)
Dividend (distribution to overseas shareholders)

Whether withholding is required and the applicable tax rate depend on the nature of the payment and current Lao tax law. If the recipient's country has a Double Taxation Agreement (DTA) with Laos (e.g., the China-Laos Tax Treaty), a lower tax rate or tax exemption may apply.

Withholding process and considerations

In practice, the payer should first determine the nature of the payment, calculate the tax to be withheld at the applicable rate, deduct it at the time of payment, and declare and pay it to the tax authority within the prescribed time limit. After withholding, the payer must provide the recipient with a tax payment certificate and retain the contract, invoice, payment voucher, and declaration records for tax inspection.

Failure to withhold or declare in time may result in additional tax and penalties. Given the complexity of specific tax rates and treaty applicability, it is advisable to consult a professional before proceeding.

Common examples

Paying overseas service fee/charge: For example, hiring a foreign designer for a project, withholding tax is generally required at the rate specified by Lao tax law. If the recipient is in China, check the China-Laos Tax Treaty for possible benefits.
Paying overseas interest: Interest paid to an overseas bank or shareholder typically requires withholding tax.
Paying overseas dividends: Dividends distributed to overseas shareholders also involve withholding tax.

FAQ

Is withholding tax always required when paying a service fee/charge to an overseas company?

According to the Lao Income Tax Law and Tax Administration Law, withholding tax is generally required when paying a service fee/charge to an overseas entity. However, whether and how much to withhold depends on the nature of the payment, current Lao tax law, and any tax treaty between Laos and the recipient's country. It is advisable to consult a professional before making the payment.

What are the consequences if withholding tax is missed?

The payer is obligated to withhold, declare, and retain records. If withholding or declaration is missed, the payer may face additional tax and penalties. The specific consequences are determined by the Lao tax authorities.

Yes, China and Laos have signed the China-Laos Tax Treaty. When making payments to a Chinese company, you can check whether the treaty provides for a reduced tax rate or tax exemption.
