Calculate the 30-day window to lodge an objection against a ZIMRA assessment under s.62 of the Income Tax Act. Don't miss the deadline — late objections require condonation.
Specific grounds in fact and law — not just "we disagree".
Exactly what you want ZIMRA to do (e.g. reduce assessment to X, withdraw penalties, etc.).
Schedules, contracts, invoices, expert opinions.
Disputed tax remains payable unless ZIMRA grants a suspension. Apply for suspension at the same time as the objection.
Show good cause for the delay. Don't assume condonation will be granted.
