The South African Revenue Service (SARS) has lowered interest rates on outstanding taxes and overpayments, effective as of 7 January 2025. 

Interest rates charged in terms of the legislation administered by SARS are split into three main categories, namely –

  • interest charged on outstanding taxes, duties and levies and those payable in respect of refunds of tax on successful appeals and certain delayed refunds
  • interest payable on credit amounts (overpayment of provisional tax) in terms of section 89quat(4) of the Income Tax Act, 1962
  • interest applicable to a loan denominated in the currency of the Republic, as described in paragraph (a) of the definition of ‘official rate of interest’ in section 1(1) of the Income Tax Act, 1962

For ease of reference, the tables of interest rates are given below in three separate documents, numbered according to the three main categories, i.e. the first group of interest rates can be found in Table 1.
