SARS has released updated interest rates, effective 1 May 2025, covering two key areas that impact tax calculations:

📌 Table 1 – Interest on Outstanding Taxes & Refunds
This rate applies when taxpayers pay taxes late—or when SARS owes interest on refunds after successful appeals or delays.

📌 Table 2 – Interest on Overpaid Provisional Tax
If a taxpayer overpays provisional tax, SARS pays interest at this rate in terms of section 89quat(4) of the Income Tax Act.

Why this matters

These rates affect how penalties, late payments, and provisional tax refunds are calculated. Staying up to date helps avoid errors and surprises for your clients.
