Laos Cross-Border Tax Guide 2026

Overview — Cross-Border Taxation

Cross-border taxation in Laos is governed by the Tax Law and regulations on international tax matters, as well as Laos's network of Double Tax Treaties (DTTs). Laos follows a territorial tax system, meaning only income sourced in Laos is subject to Laotian tax. Payments to non-residents are generally subject to withholding tax (WHT) at source, with rates potentially reduced under applicable DTTs. The Tax Department has strengthened its international tax compliance capabilities, including transfer pricing audits and exchange of information under treaty frameworks.

Withholding Tax Rates

Payments are subject to withholding tax at the following standard rates:

• Dividends: 10% WHT (residents), 20% WHT (non-residents)
• Interest: 10% WHT (residents), 20% WHT (non-residents)
• Royalties: 10% WHT (residents), 20% WHT (non-residents)
• Services: Varies depending on the nature of services and residency of the recipient
• Branch remittances: Subject to WHT on after-tax profits remitted by a branch to its head office

These rates may be reduced under applicable DTTs. The Laotian payer must withhold and remit the tax within the prescribed timeframe.

Double Tax Treaties (DTTs)

Laos has signed and ratified approximately 10-12 double tax treaties, generally following the OECD Model Convention. Key treaties include:

• East Asia: China, Korea, Japan
• ASEAN: Vietnam, Thailand, Cambodia, Myanmar
• Other: Treaties with additional countries are under negotiation or in force

DTTs typically reduce WHT rates on dividends, interest, and royalties, and provide for the elimination of double taxation through foreign tax credit or exemption methods. They also include mutual agreement procedures for dispute resolution and exchange of information provisions.

Transfer Pricing

Laos has introduced transfer pricing rules aligned with OECD Transfer Pricing Guidelines. Requirements:

• Arm's length principle: All related-party transactions must be at arm's length
• Documentation: Taxpayers must prepare contemporaneous transfer pricing documentation
• Related parties: Includes direct and indirect control, management influence, and family relationships
• TP return: Annual transfer pricing declaration must be filed with the CIT return
• Penalties: Adjustments can result in additional tax plus penalties and interest

Thin capitalisation rules limit interest deductions on related-party debt. Advance Pricing Agreements (APAs) are available for taxpayers seeking certainty on transfer pricing matters.

Permanent Establishment (PE)

A foreign company with a Permanent Establishment (PE) in Laos is subject to Laotian CIT at 20% on profits attributable to the PE. A PE is created if the foreign company has:

• A fixed place of business in Laos (office, branch, factory, workshop, construction site)
• A dependent agent with authority to conclude contracts in Laos
• Service presence exceeding a prescribed period

Foreign companies with a PE must register with the Tax Department and file CIT returns. Without a PE, foreign companies are subject only to final withholding tax on Lao-source income.

FAQs
