The appellant, FMC Finance (Private) Limited, operates a microfinance business with customers primarily from public service employees and State organs. The appellant had agreements with State institutions (Zimbabwe National Army, Public Service Commission) whereby these institutions would deduct loan repayments from employees' salaries and remit them to the appellant. In return, the appellant paid commissions of 2.5% to 5% to these institutions. The respondent, Zimbabwe Revenue Authority (ZIMRA), investigated and found that the appellant failed to withhold 10% from commissions paid to institutions without valid tax clearance certificates as required by Section 80(2) of the Income Tax Act. ZIMRA issued assessments for withholding tax totaling ZWL$1,139,279.08 (later revised to ZWL$783,913.65), plus penalties and interest. The appellant objected to the assessments, the objection was disallowed, and the appellant noted an appeal. On the eve of the hearing, the appellant filed supplementary heads of argument raising new legal points: that the assessments did not contain taxable income and were unlawful; an assessment cannot be subject to audit; and ZIMRA could not issue an assessment for withholding tax. Both counsel conceded that the assessments were irregularly issued and defective, agreeing the appeal should be struck off but disagreeing on costs.
