South Africa collected R1.25-trillion in tax revenue in the financial year ended March 2021, around 12% less than the government's original target of R1.425-trillion, the revenue service said on Thursday.
The initial 2020/21 target was set by the National Treasury before the coronavirus pandemic struck in March last year.
Treasury revised the estimate down to R1.112-trillion in October, but then upped it to R1.212-trillion in the February 2021 budget.
The South African Revenue Service (Sars) said improved economic activity, higher collections company tax, especially mining firms, and greater tax compliance, had led to better collection than the February target.
Sars Commissioner Edward Kieswatter said the agency would focus on stricter compliance, especially by high net-worth individuals, to close the gap.
"Sars is aware of increasing number of south Africans who have financial assets offshore ... they have more than R400-billion in offshore accounts. We've identified around 10% of that, but we believe there's still a lot to be explained," Kieswatter told a news conference.
Kieswatter said the bans on the sale of alcohol and tobacco during the strictest period of the coronavirus lockdown cost the country around R14-billion in lost excise taxes.
