The verdict in three sentences
In Uganda, MTN MoMo and Airtel Money hold the vast majority of wallets, so a Kampala merchant should accept both. A 0.5 % mobile money tax on withdrawals sits on top of operator fees and must be built into your displayed prices. In 2026 the smart play is dual acceptance plus API automation, since MoMo leads on base while Airtel undercuts slightly on transfer.
Fees per amount in Kampala
Compare on your real baskets, not headline rates. Here is the 2026 order-of-magnitude for customer-side fees in Uganda.
| Amount | MTN MoMo Uganda | Airtel Money Uganda |
|---|---|---|
| UGX 20,000 | UGX 100-200 | UGX 100 |
| UGX 50,000 | UGX 350 | UGX 300 |
| UGX 100,000 | UGX 700 | UGX 600 |
| UGX 500,000 | UGX 1,500 | UGX 1,400 |
| Withdrawal tax | +0.5 % | +0.5 % |
The 0.5 % withdrawal tax applies on cash-out, so a customer who keeps money in-wallet and pays merchants directly avoids it — a good reason to push digital acceptance.
The Mali parallel: Wave vs Orange Money
West Africa offers a contrasting model, where Wave's free cash-out disrupts the incumbent Orange Money.
| Criterion | Wave Mali | Orange Money Mali |
|---|---|---|
| Transfer fee | 1 % (cap ~500 FCFA) | 1.5 - 2 % |
| Withdrawal fee | Free | ~1.5 % |
| Settlement | T+1 | T+1/T+2 |
| Wallet limit | 2,000,000 FCFA | 2,000,000 FCFA |
| Agent network | Growing (urban) | Very dense (national) |
| API | Wave Business API | OM API |
Mali's Wave eliminates cash-out cost entirely, whereas Uganda layers a withdrawal tax on top — a structural difference worth understanding if you operate across regions.
Mini case study
Grace, who runs an auto-parts shop in Kampala (Nakawa), processes UGX 25,000,000 a month over 200 sales. Accepting both MTN MoMo and Airtel Money, she pushes customers to pay her merchant number directly so they skip the 0.5 % withdrawal tax on their side, improving her close rate. She wires the MTN Uganda API into her POS for auto-reconciliation, cutting manual entry errors and saving several hours of bookkeeping each week.
