How to File IT1 on iTax
Step-by-step guide to uploading your IT1 on the KRA iTax portal for Tax Year 2025.
Download the official IT1 template from KRA
Go to itax.kra.go.ke → Log in with your KRA PIN and password → Navigate to Returns → Download Return → Select Income Tax - Individual (IT1) → Download the Excel file (ends in .xlsm).
Log back into iTax and file your return
Back on itax.kra.go.ke → Click Returns → File Return → Select Income Tax - Resident Individual → Select Year 2025 → Click Upload Excel Return.
Upload the ZidiTax-filled IT1 file
Select the .xlsm file downloaded from ZidiTax. iTax will parse the file and display all values. Review carefully — confirm gross income, PAYE paid, reliefs, and net tax payable match your ZidiTax summary. Click Submit.
Pay and download acknowledgment
If tax is due, generate a payment slip → Pay via M-Pesa or bank transfer using the generated reference number. Once payment is confirmed, download your e-Acknowledgment Receipt — keep this as proof of filing. Upload a copy to your ZidiTax Document Vault.
