West Africa Is Taxing Mobile Money Again. Here's What It Costs Your Business.

Several West African governments are introducing new taxes on mobile money transfers. Senegal, Cameroon, and Mali are all moving to charge customers a fee on every transaction. For small business owners who rely on mobile money to pay suppliers and receive customer payments, the cost adds up fast. And Ghana's experience shows exactly how this tends to end.

What Governments Are Charging

Three countries have introduced or tightened mobile money taxes in recent months.

Senegal introduced a 0.5% tax on every mobile money transfer. Merchant payments face an additional 1.5% levy, plus an extra 2% fee charged directly to merchants. The government expects to raise CFA 220 to 230 billion (around $388 to $405 million) over three years.

Cameroon has a 0.2% levy on each transfer and cash withdrawal, plus a flat CFA4 fee per transaction added in 2025. Mobile money already accounts for nearly 50% of Cameroon's GDP by transaction volume.

Mali raised the tax on mobile operator revenues from 8% to 10% and introduced a 1% levy on mobile money withdrawals.

These are not small numbers. For a business sending or receiving money dozens of times a week, the fees compound quickly.

Ghana Tried This. It Failed.

Ghana launched its E-Levy in 2022. It charged 1.5% on all electronic transfers above a small daily threshold. The government projected it would raise GHS 6.9 billion in its first year.

It raised GHS 328 million, less than 5% of the target.

Within weeks of the tax going live, transaction volumes dropped sharply. A GSMA study found usage fell by around 25% and platform revenues dropped 20%. People switched back to cash. Businesses that had moved their operations onto mobile money started reverting.

Ghana repealed the E-Levy in May 2025 after three years of poor revenue collection and clear evidence it was hurting financial inclusion.

Transaction-based taxes introduced in Cameroon, Mali, and Senegal are pushing users back to cash, repeating a pattern already seen in Ghana and other markets.

Senegal's government says its situation is different. But the mechanics are the same: raise the cost of a digital transaction, and some portion of users stop using it.

What the Math Looks Like for Your Shop

The impact depends on how you use mobile money.

If you receive customer payments in Senegal, the merchant levy means you are paying 1.5% on every transfer you receive, plus another 2% fee. On a CFA 50,000 payment, that is CFA 750 from the levy and CFA 1,000 from the merchant fee. CFA 1,750 gone before the money reaches you.

If you pay suppliers by mobile transfer, the 0.5% transaction tax applies. On CFA 200,000 in supplier payments per week, that is CFA 1,000 per week. Around CFA 52,000 per year, roughly equivalent to a week of small customer purchases.

In Cameroon, the 0.2% plus flat-fee structure is smaller per transaction. But it hits high-volume businesses hard. Shops processing dozens of small payments daily accumulate significant fees across a month.

These amounts are not catastrophic for a large business. But for a market seller or kiosk operator running on thin margins, they change the calculation on whether mobile money is worth using at all.

Will Customers Go Back to Cash?

Some already are. Industry groups in Senegal have warned that market women, motorcycle taxi drivers, and informal workers who rely on digital wallets daily are the most exposed. They make frequent small payments. A 0.5% fee on many small transactions is a bigger burden than the same rate applied to one large payment.

When mobile money becomes more expensive, the research is consistent: cash use goes up. Ghana's experience showed an immediate shift. Transaction volumes fell, agent network income fell with them, and businesses lost the record-keeping and security benefits they had built around digital payments.

The concern is not just the fees. Businesses that used mobile money built routines around it. Digital receipts, instant supplier settlements, credit history from transaction records. Going back to cash means losing those tools.

Africa's mobile money market reached $1.4 trillion in transaction value in 2025, according to GSMA data. Sub-Saharan Africa accounts for roughly 66% of all global mobile money transaction value. That infrastructure did not appear overnight. Policies that chip away at it carry real costs beyond the direct levy.

Why This Matters

Mobile money is not just a payment tool for small businesses in West Africa. It is how many of them manage cash flow, settle with suppliers, pay staff, and build a financial record. For a kiosk owner or market vendor who never had a bank account, their mobile wallet is their bank.

A transaction tax makes every one of those actions more expensive. It does not distinguish between a large company moving millions and a trader paying for a bag of tomatoes. The fee is proportional. But the burden falls hardest on the people making the most frequent, smallest transactions.

If you operate in Senegal, Cameroon, or Mali, now is the time to review your payment volumes and calculate your actual costs. Some businesses may find the fees are manageable. Others may find that certain transaction types no longer make sense through mobile money.

Conclusion

Mobile money taxes are back in West Africa, and the lesson from Ghana's e-levy is clear: they tend to hurt more than they raise. If you run a shop or stall in an affected country, check what the new rates mean for your transaction patterns. And watch whether your customers start asking for cash again.
