Ghana’s Sentinal System: A New Era in Digital Tax Collection for Foreign Platforms
Ghana is set to revolutionise the collection of Value Added Tax (VAT) on digital services provided by foreign entities with the imminent rollout of the Sentinal System, an initiative by the Ghana Revenue Authority (GRA). Scheduled to commence on October 15, 2026, this sophisticated mechanism, operating under the Real-Time VAT (RTVAT) framework, aims to ensure that foreign digital platforms contribute their fair share to the nation’s revenue without imposing any new taxes on Ghanaian consumers or businesses.
The core principle behind Sentinal is not the introduction of new levies, but a more effective collection method for existing taxes. Since 2022, Ghanaian law has mandated that foreign providers of digital services register with the GRA and charge VAT on sales to Ghanaian customers. However, the previous system’s reliance on voluntary declarations by these companies proved insufficient, leading to significant revenue leakage. The Value Added Tax Act, 2025 (Act 1151), which came into effect on January 1, 2026, provides the legal bedrock for this reform, having already streamlined the tax structure by removing a 1 per cent levy, consolidating the total tax rate at 20 per cent (15% VAT, 2.5% NHIL, and 2.5% GETFund Levy).
Sentinal functions as an automated checkpoint integrated with Ghana’s existing financial infrastructure, including banks, mobile money operators, and payment service providers. The system is triggered when a transaction meets three specific criteria: payment is made using a Ghana-issued card, mobile money account, or digital wallet; the seller is a non-resident business; and the service is delivered electronically, such as streaming, cloud storage, or software subscriptions. Crucially, everyday transactions like local mobile money payments or utility bill settlements remain unaffected.
Under the Sentinal system, when a Ghanaian consumer purchases a service from a foreign digital provider, the VAT and levies are calculated and withheld at the point of payment. For instance, a GH¢100 service would incur an additional GH¢20 in taxes, with the GH¢100 remitted to the merchant and the GH¢20 held by the payment provider as a withholding agent for the GRA. This real-time deduction ensures immediate remittance, eliminating the delays and uncertainties of self-declaration. Refunds and chargebacks are also automatically reversed, with recourse available through the payment provider for any erroneous charges.
Concerns regarding double taxation and price increases have been addressed by the GRA. The system adheres to international tax principles, taxing services where they are consumed. Foreign merchants registered under the Simplified VAT Regime will have these real-time collections reconciled with their VAT returns, preventing any instance of double payment. Furthermore, for foreign companies that were already compliant with VAT regulations, customer costs are expected to remain unchanged. The reform primarily targets foreign entities that previously evaded their tax obligations, thereby levelling the playing field for local Ghanaian businesses.
Ghana’s adoption of Sentinal aligns with global trends, as countries like the EU, South Africa, Kenya, Nigeria, and New Zealand have implemented similar measures to tax foreign digital services. The GRA estimates that Sentinal could have generated over GH¢2.5 billion in 2025 alone, revenue that will bolster essential public services like healthcare and education. The authority also cautions that transactions outside the RTVAT scope, such as SWIFT transfers or payments via foreign cards, are not exempt from VAT and may fall under other tax regimes. Foreign merchants are reminded of their ongoing obligations to display prices exclusive of VAT, notify customers of the added tax, maintain records, and remain VAT-registered.
