The applicant, a small company, filed income tax self-assessment returns with the Zimbabwe Revenue Authority (ZIMRA) in July 2010 for the 2009 and 2010 financial years. ZIMRA conducted audits and issued initial assessments showing tax liabilities of USD$140,785.20 (2009) and USD$48,253.87 (2010) with penalties. A garnishee order was imposed in 2012 but uplifted after parties reached a compromise. ZIMRA later issued amended assessments showing reduced liabilities of USD$78,604.62 (2009) and USD$32,464.63 (2010). In April 2012, the applicant acknowledged these debts in writing and requested reduced penalties. In October 2015, ZIMRA finalized a new audit showing further reduced liabilities of USD$20,546.03 (2009) and USD$68,588.46 (2010), which it termed "final" and demanded immediate payment. Despite this final audit, in March 2016 ZIMRA imposed garnishee orders on the applicant's bank accounts based on the earlier 2012 assessment figures rather than the 2015 final audit results. The applicant challenged this as unlawful, unreasonable, and contrary to its legitimate expectations under the Administrative Justice Act and the Constitution.
1. The decision by the respondent imposing garnishee orders against the applicant's bank accounts is set aside and all garnishee orders issued by respondent are uplifted forthwith. 2. The respondent is ordered to return all monies it garnished from applicant's bank account as from 31 March 2016. 3. The respondent is ordered to finalize the applicant's tax audit for the 2009 and 2010 financial years considering all payments made towards the tax obligations. 4. The respondent to pay costs.
Where a tax authority conducts a final audit showing reduced tax liability compared to earlier assessments and explicitly terms its findings as "final," it acts unlawfully, irrationally, and in breach of the taxpayer's legitimate expectations if it subsequently imposes garnishee orders based on the earlier, higher assessments rather than the final audit results. An administrative authority exercising statutory powers must act lawfully (within statutory authorization), rationally (complying with the logical framework of the power granted), consistently, fairly (impartially with opportunity to be heard), and in good faith. When a tax authority establishes through audit that a taxpayer has been charged tax in excess of what is properly due, it is obliged under section 48(1) of the Income Tax Act to issue amended assessments reflecting the reduced liability before taking enforcement action. Failure to do so renders subsequent enforcement action unlawful. Courts will intervene to set aside administrative decisions by revenue authorities that fail to meet the constitutional requirements of administrative justice, even though revenue collection is important to the fiscus. The obligation to pay tax pending objection or appeal under section 69 of the Income Tax Act does not suspend judicial review of unlawful administrative action or protect arbitrary exercise of administrative power.
The court observed that as a revenue collector, the respondent should not be bogged down by a single entity continuously challenging its findings by filing new documents, suggesting that finality is important in tax administration. The court noted that judging by the applicant's income figures, it was a small company and an audit for two years should not take more than six years, implying criticism of the protracted nature of the audit process. The court remarked that it was "but for technicalities and the arbitrary way in which the respondent handled this income tax issue that applicant has been able to succeed," suggesting that proper administrative procedure by ZIMRA would have avoided this litigation. The court cited with approval the principle from Affretair (Pvt) Ltd v MK Airlines that courts must guard against usurping administrative bodies' functions and should ensure they carry out functions fairly and transparently rather than substituting their own judgment for that of the authority. However, the court emphasized that where functions have not been carried out fairly, transparently, lawfully, and rationally, courts have a duty to intervene.
This case is significant in Zimbabwean administrative law (and relevant to South African jurisprudence by analogy given similar constitutional provisions on administrative justice) as it reinforces the constitutional right to administrative justice and the courts' willingness to review and set aside arbitrary administrative action by revenue authorities. The judgment emphasizes that tax authorities must exercise their powers lawfully, rationally, fairly, and in good faith, even in the context of tax collection which is vital to the fiscus. It establishes that administrative authorities cannot arbitrarily revert to outdated findings when more recent assessments favorable to taxpayers have been finalized, as this violates legitimate expectations and the principles of rationality and fairness. The case demonstrates that courts will intervene to uphold administrative justice principles where authorities abuse discretion or fail to follow proper procedures, even in specialized areas like tax administration. It also clarifies that section 69 protection (obligation to pay pending appeals) does not shield unlawful administrative action from judicial review.
