The 1.5% rate and the KES 1M / 25M band live on a Rates tab, each dated and sourced, so if KRA moves a figure you change one cell. Enter your monthly gross sales and the sheet computes ToT per month, your cumulative turnover for the year, and the annual total. The Dashboard tells you plainly whether you're below the band (ToT optional), inside it (file 1.5% monthly), or above KES 25M (time to register for VAT and normal tax).
ToT is charged on gross sales with no expense deductions and is filed monthly by the 20th — the guide spells this out. Opens in Excel or Google Sheets. Always confirm current rates at kra.go.ke before filing.
