How do I calculate provisional tax in South Africa?
# How to Calculate Provisional Tax in South Africa
Provisional tax in South Africa is calculated based on **estimated taxable income** for the current tax year. You must pay provisional tax if your total tax liability (excluding PAYE) will exceed **R1,000** for the year.
## Who Must Pay Provisional Tax
You're liable for provisional tax if you:
- Earn business income, rental income, or investment income
- Are a company, trust, or individual with non-salary income
- Expect your tax liability to exceed R1,000 for the tax year
**Exemption**: Individuals whose only income is salary (subject to PAYE) and whose total tax liability won't exceed R1,000.
## Calculation Methods
### Method 1: Basic Amount (IRP6)
SARS issues an IRP6 with a **basic amount** based on your previous year's assessment. This is the simplest method.
**First Payment**: 50% of the basic amount
**Second Payment**: 100% of the basic amount, less the first payment
### Method 2: Estimate Method
Calculate based on your estimated taxable income for the current year.
**Formula**:
1. Calculate normal tax on estimated taxable income
2. **First Payment**: 50% of estimated tax liability
3. **Second Payment**: 100% of estimated tax liability, less first payment and any PAYE credits
### Method 3: Prior Year Method
Use 100% of the previous year's actual tax liability as your provisional tax for the current year.
## Calculation Example
**Estimated taxable income**: R500,000
**Normal tax calculation** (2024/25 rates):
- Tax on R500,000 = R101,829
**Provisional tax payments**:
- **First payment**: R101,829 ÷ 2 = **R50,915**
- **Second payment**: R101,829 - R50,915 = **R50,914**
## Payment Deadlines
- **First payment**: End of August (6 months after tax year start)
- **Second payment**: End of February (last day of tax year)
## Important Considerations
**Penalties apply** if you underestimate by more than 20% or R1,000 (whichever is greater). SARS charges interest on late payments at the prescribed rate.
**Top-up payments** may be required if your estimate was too low when filing your annual return.
**Companies** follow the same calculation principles but use the 27% corporate tax rate.
