Discounts and VAT in South Africa: which comes first?
Whether VAT in South Africa is charged before or after a discount, with a worked example and the difference in what the customer pays.
Key facts
| Place | South Africa |
|---|---|
| Tax | VAT |
| Standard rate on file | 15% |
| Multiply net price by | 1.15 |
| Tax share of a gross price | 13.04% |
| Currency | ZAR |
Discount first, then tax
In general the discount reduces the taxable amount, and VAT at 15% is charged on the reduced price. If a 15% discount is applied to a net price, the tax is calculated on the remaining 85%.
Worked example
Here is the calculation with sample figures. Change any number in the South Africa Discount and VAT Calculator to run your own.
| Price | ZAR600.00 |
| Discount (%) | 15% |
| Tax rate (%) | 15% |
| Discount | ZAR90.00 |
|---|---|
| Net amount | ZAR510.00 |
| Tax | ZAR76.50 |
| Total | ZAR586.50 |
Does the order change the total?
Mathematically, applying a percentage discount and a percentage tax gives the same final price in either order. What changes is the tax amount you record and report, and that must reflect the price actually charged.
Vouchers and coupons
Store vouchers, manufacturer coupons and gift cards can each be treated differently. Some reduce the taxable price, others are treated as a form of payment. Check how each type is handled in South Africa before you run a promotion.

Key terms

- Tax deducted at source, by an employer or payer, before the money reaches you.
- Reduced rate
- A lower rate that applies to specific categories, often essentials such as food, medicine or books.
- Deduction
- An amount subtracted from taxable income. It saves tax equal to the deduction times your marginal rate.
Common mistakes to avoid
- Charging tax on the full list price after giving a discount.
- Treating gift cards as discounts.
- Advertising a discount on the gross price but calculating it on the net price.
