Capital gains tax in Kenya can be paid in installments or at the end of the tax period. The payment is initiated online by selecting capital gains tax under the income tax subhead, choosing the applicable CGT type based on the transaction, selecting self-assessment as the payment type, and either cash or cheque as the payment mode. This generates an e-slip used to make the payment through deposit at a bank or via M-Pesa using the pay bill number 572572 and the payment registration number on the e-slip as the account number.
