The verdict in three sentences
Collecting referral commissions in undeclared cash exposes you to assessment and blocks any access to credit or formal contracts. Under a presumptive or turnover-tax regime, a partner on GHS 34,000 of annual commissions keeps 85 to 92 % net in 2026, once expenses are deducted. The key: invoice every commission, keep the Mobile Money/bank trail, and pick the right regime from the start.
Informal vs declared: your risk and your gain
Informal cash seems to "keep 100 %" but builds nothing: no provable income, no credit, and a risk of assessment with penalties. The declared regime costs a moderate tax but turns your commissions into bankable, secure income.
| Criterion | Informal cash | Declared (self-employed) |
|---|---|---|
| Apparent tax | 0 % | 3 to 15 % by regime |
| Assessment risk | high (+ penalties) | none |
| Provable income (credit, lease) | no | yes |
| Expense deduction | impossible | yes |
| Access to formal contracts/agencies | limited | full |
| MoMo/bank traceability | uncontrolled | managed |
Regimes, thresholds and deductible expenses 2026
In anglophone markets (Ghana, Nigeria, Kenya), personal income tax bands or a presumptive/turnover tax apply to small earners, often with withholding by the paying agency. Watch the VAT threshold above which you must charge the tax.
| Item | 2026 order of magnitude | Note |
|---|---|---|
| Presumptive / turnover tax | 3 to 8 % of turnover | by country and band |
| Possible withholding at source | ~5 % | deducted by paying agency |
| Indicative VAT threshold | varies by country | above it, charge VAT |
| Deductible expenses | phone, data, transport, equipment | with receipts |
| Income tax bands | progressive | on higher earnings |
Deductible expenses (phone/data plan, prospecting travel, a laptop) shrink the taxable base and should be documented systematically.
Mini case study
Ama, a referral partner in Accra, collects GHS 34,000 of Kolonell commissions over the year (showcase at 15 %, e-commerce at 12 %, plus 5 % recurring). She opts for the presumptive regime.
She deducts GHS 3,700 of real expenses (data, transport, phone): her base drops to GHS 30,300. At a 6 % presumptive rate, she pays about GHS 1,820 in tax. The agency already withheld 5 %, which she reconciles. Net in her pocket: about GHS 28,400, or 84 % kept, with 100 % provable income for credit or a lease.

FAQ
Do referral commissions need to be reported?
Yes. Beyond one-off use, these commissions are taxable income. Reporting them under a self-employed or presumptive regime costs 3 to 15 % but removes any assessment risk and makes your income bankable.
How much is left net on GHS 34,000 of commissions in 2026?
After deductible expenses and presumptive tax, a partner typically keeps 85 to 92 % net, around GHS 29,000 to 31,000. The exact figure depends on the country, regime and documented expenses.
What is withholding at source?
Some agencies deduct ~5 % directly from the commission paid and remit it to the tax authority on your behalf. It is a tax advance; you reconcile it in your annual return.
Which expenses can I deduct?
Phone, data plan, prospecting travel, computer equipment, within reason and with receipts. These expenses reduce your taxable base, so document them from the first month.
Is the Mobile Money trail a problem?
Quite the opposite: managed well, it proves your income for credit or a lease. The problem is undeclared informal cash. An invoiced, tracked commission is an asset, not a risk.
