Gambia Cross-Border Tax Guide 2026

Overview — Cross-Border Taxation in Gambia

Gambia's cross-border tax rules are governed by the Income and VAT Act and administered by the Gambia Revenue Authority (GRA). As a territorial jurisdiction, Gambia taxes only income derived from or accruing in Gambia. This makes Gambia an attractive location for holding companies and regional headquarters. Multinational enterprises operating in Gambia must comply with transfer pricing documentation requirements and withholding tax obligations. As a member of ECOWAS (Economic Community of West African States), Gambia applies regional trade agreements and investment protocols.

Transfer Pricing — Arm's Length Principle

Gambia's transfer pricing rules require that transactions between related parties be priced at arm's length. Related parties include companies under common control, parent-subsidiary relationships, and individuals with significant influence. Documentation requirements include contemporaneous documentation for transactions exceeding specified thresholds. Acceptable transfer pricing methods include the Comparable Uncontrolled Price (CUP) method, Cost Plus method, Resale Price method, and Transactional Net Margin Method (TNMM). Penalties for non-compliance can be significant. The GRA has been building its transfer pricing audit capacity.

Withholding Taxes to Non-Residents

Payments to non-residents from Gambia-source income are subject to withholding tax at the following standard rates (treaty rates may apply):

• Dividends — 15%
• Interest — 15%
• Royalties — 20%
• Management fees — 15%
• Technical service fees — 15%
• Rent (commercial property) — 15%

The person making the payment must withhold the tax and remit it to GRA within 15 days. A withholding tax certificate must be issued to the non-resident.

ECOWAS Regional Framework

As a member of ECOWAS (Economic Community of West African States), Gambia participates in regional economic integration including:

• Free trade area — preferential tariff treatment for goods originating from ECOWAS member states
• Investment facilitation — ECOWAS Investment Protocol providing protections for cross-border investors
• Tax cooperation — regional initiatives for tax information exchange and combating tax evasion
• Common external tariff — harmonised customs duties on imports from outside ECOWAS

ECOWAS member states are Benin, Burkina Faso, Cabo Verde, Côte d'Ivoire, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Niger, Nigeria, Senegal, Sierra Leone, and Togo.

Double Tax Treaties

Gambia has a limited network of double tax treaties. As of 2026, Gambia has signed comprehensive DTTs including with the United Kingdom and certain other Commonwealth countries. Gambia also has tax information exchange agreements (TIEAs) with several jurisdictions. To claim treaty benefits, a non-resident must obtain a Certificate of Tax Residency from their home country tax authority and submit a treaty relief application to GRA.

FAQs

Do I need to register for tax in Gambia as a non-resident investor?

Non-residents earning Gambia-source income subject to final withholding tax generally do not need to register. However, a non-resident with a permanent establishment in Gambia must register and file corporate tax returns.

How do I claim a refund of excess WHT?

A non-resident may claim a refund if WHT was deducted at the full statutory rate when a reduced treaty rate should have applied. The refund claim is submitted to GRA with supporting documents.

Does Gambia have a General Anti-Avoidance Rule?

Yes, the Income and VAT Act includes general anti-avoidance provisions that allow GRA to recharacterise transactions entered into for tax avoidance purposes.
