How do traders account for invoices raised in foreign currency?

The unit of currency to feature in books of account, tax returns and tax invoices must be in Kenya shillings as per Section 23 of the Tax Procedures Act. Taxpayers are advised to convert the foreign currency into the Kenyan shilling equivalent value using the prevailing CBK mean rate for the day. The foreign currency values may appear on the invoice, however, for tax purposes reference will be made to the Kenya shilling values.
