Failing to pay taxes on time can result in interest charges imposed by SARS. Understanding how interest on late payments is calculated is crucial for taxpayers to avoid surprises and manage their tax liabilities effectively. This detailed guide explains SARS’s methods for calculating interest on overdue tax amounts, how rates are determined, and tips to minimize interest costs.
Why Does SARS Charge Interest on Late Payments?
SARS charges interest on late tax payments to compensate for the time value of money lost due to delayed payments. This also serves as a deterrent to encourage timely compliance with tax obligations.
How SARS Calculates Interest on Late Payments
Interest on late payments is calculated daily on the outstanding tax amount from the due date until full payment is made. Key points include:
- Interest accrues on the total unpaid tax, including penalties and penalties that remain unpaid.
- The calculation uses a simple interest formula rather than compound interest.
- Interest is calculated at a prescribed rate determined quarterly by SARS.
Simple Interest Calculation Formula
SARS applies the following formula for calculating interest on late payments:
Interest = Principal Amount × Interest Rate × (Number of Days Late / 365)
Where:
- Principal Amount: The unpaid tax amount.
- Interest Rate: The SARS prescribed interest rate for the relevant period.
- Number of Days Late: Days from the payment due date to the actual payment date.

Prescribed Interest Rates by SARS
SARS updates the interest rates quarterly, reflecting prevailing economic conditions. Rates are published on the SARS website and are applicable for specific periods. It is important to check the current rate when calculating interest.
Examples of Interest Calculation
Suppose you have an outstanding tax debt of R50,000, and the SARS interest rate is 7% per annum. If the payment is 30 days late, the interest would be:
Interest = 50,000 × 7% × (30/365) = R287.67
Impact of Interest on Tax Planning
- Delaying payments increases interest costs, adding to overall tax liabilities.
- Making partial payments can reduce the principal and therefore the interest charged.
- Keeping abreast of SARS deadlines helps avoid interest and penalties.
How to Minimize Interest on Late Payments
- File and pay taxes on or before due dates.
- Use SARS eFiling for convenient and timely payments.
- If unable to pay in full, negotiate payment arrangements with SARS promptly.
- Maintain clear communication with SARS to avoid misunderstandings.
Conclusion
Interest on late tax payments can quickly increase your tax burden if not managed properly. By understanding SARS’s calculation methods and prescribed rates, taxpayers can plan payments effectively, avoid unnecessary costs, and maintain good standing with SARS.
