In December 2011, the Zimbabwe Revenue Authority (respondent) contended that Delta Beverages (applicant) had underestimated its provisional tax payments for 2009 and 2010, and demanded payment of interest totaling US$698,864.48. To avoid garnishment of its bank account, the applicant paid the demanded interest in three instalments in September, October and November 2012. The applicant challenged the respondent's right to payment of such interest in the High Court. In case HC 9715/12 decided on 29 January 2015, the court held that the applicant had no obligation to pay that interest and that the respondent was obligated to waive payment. The respondent credited the applicant with the amount but did not pay interest on the sum that had been unlawfully demanded and held from 2012 until refund in March 2015. The applicant demanded refund on 19 February 2015 and payment was made on 14 March 2015. The applicant then sought a declaration that the respondent was obliged to pay interest at 10% per annum on the refunded amount for the period it was held.
1. The application is dismissed. 2. The applicant to pay the respondent's costs.
The binding legal principles established are: (1) The relationship between a taxpayer and tax authority is sui generis and primarily governed by statute, not common law principles of contract or delict; (2) Section 48(3) of the Income Tax Act imposes an obligation on the Commissioner to pay interest on refunded tax only if the refund is not made within 60 days from the date of demand by the taxpayer; (3) Section 48(3) operates prospectively, requiring interest only for delays after the 60-day period, not retrospectively for the entire period the funds were held; (4) The "pay now, argue later" principle under section 69 of the Income Tax Act is lawful and does not constitute unlawful deprivation of funds; (5) The Prescribed Rate of Interest Act does not apply where specific statutory provisions (such as section 48(3)) govern the transaction.
The court observed that while under common law there is no immunity for the fiscus from payment of mora interest (following COT v Kristianten), this principle has been superseded by specific statutory provisions in the Income Tax Act. The court noted that the applicant did not formally request the Commissioner to suspend the continuing obligation to pay the charged tax pending determination of the dispute, which was a mechanism available under section 69 to ameliorate financial hardships. The court commented that mechanisms were put in place to address hardships from the "pay now, argue later" rule, but these require the taxpayer to place relevant facts before the Commissioner as they are within the exclusive knowledge of the taxpayer.
This case clarifies the application of section 48(3) of the Income Tax Act regarding when the Zimbabwe Revenue Authority is obliged to pay interest on tax refunds. It establishes that the obligation to pay interest arises only when refunds are not made within 60 days of demand, and that the provision operates prospectively rather than retrospectively. The case reinforces the principle that the relationship between tax authorities and taxpayers is governed by statute rather than common law principles of contract or delict, and affirms the "pay now, argue later" principle in tax administration as lawful under section 69 of the Income Tax Act. It distinguishes the earlier authority in COT v Kristianten by recognizing that statutory provisions now specifically address interest on tax refunds.
