To calculate tax on income is a crucial aspect of financial planning for individuals and businesses in South Africa. Understanding how tax brackets, thresholds, and rebates work can help you make informed decisions and ensure compliance with tax regulations. This guide will walk you through the process of calculating tax on income using the most recent tax tables, providing you with a clear and easy-to-understand approach.
Understanding South Africa’s Tax Structure
South Africa employs a progressive tax system, meaning the rate of tax increases as income increases. The tax rates are structured into different income brackets, with each bracket having a specific percentage of tax applied to it. The higher your income, the higher the percentage of tax you will pay on the income that falls within each bracket.
Below, we’ll break down the steps to calculate tax on income, using the tax tables for the 2024/2025 tax year.
Step 1: Determine Your Taxable Income
Your taxable income is the total income you earn in a year, minus any deductions or exemptions allowed by the South African Revenue Service (SARS). This includes your salary, bonuses, interest from investments, rental income, and any other form of income. Common deductions include contributions to a retirement annuity fund, medical expenses exceeding the threshold, and donations to a public benefit organization.
Step 2: Identify Your Tax Bracket
Once you have your taxable income, the next step is to identify which tax bracket it falls into. Below are the tax brackets and their corresponding rates for the 2024/2025 tax year:
| Taxable Income (R) | Rates of Tax (R) |
|---|---|
| 1 – 237 100 | 18% of taxable income |
| 237 101 – 370 500 | 42 678 + 26% of taxable income above 237 100 |
| 370 501 – 512 800 | 77 362 + 31% of taxable income above 370 500 |
| 512 801 – 673 000 | 121 475 + 36% of taxable income above 512 800 |
| 673 001 – 857 900 | 179 147 + 39% of taxable income above 673 000 |
| 857 901 – 1 817 000 | 251 258 + 41% of taxable income above 857 900 |
| 1 817 001 and above | 644 489 + 45% of taxable income above 1 817 000 |
Step 3: Calculate the Tax Payable
To calculate the tax payable, you’ll apply the tax rate for your income bracket to your taxable income. Let’s work through an example to demonstrate this.
Example: Suppose your taxable income is R500,000 for the year. Here’s how you would calculate your tax:
- Identify the bracket: R500,000 falls within the third bracket (R370,501 – R512,800).
- Base tax for the lower bracket: R77,362 (base tax for the third bracket).
- Calculate tax on income above R370,500:
- R500,000 – R370,500 = R129,500
- Tax on R129,500 at 31% = R129,500 * 0.31 = R40,145
- Total tax payable:
- R77,362 + R40,145 = R117,507
Thus, the tax payable on a taxable income of R500,000 would be R117,507 for the year.
Step 4: Apply Tax Rebates
South African taxpayers are entitled to certain rebates based on their age. These rebates reduce the amount of tax you owe. For the 2024/2025 tax year, the rebates are as follows:
| Tax Rebate | 2025 (R) | 2024 (R) | 2023 (R) | 2022 (R) |
|---|---|---|---|---|
| Primary (All taxpayers) | 17 235 | 17 235 | 16 425 | 15 714 |
| Secondary (65 and older) | 9 444 | 9 444 | 9 000 | 8 613 |
| Tertiary (75 and older) | 3 145 | 3 145 | 2 997 | 2 871 |
Continuing the example:
- Assume you are under 65 years old.
- Your tax rebate would be R17,235.
Final tax payable:
- R117,507 – R17,235 = R100,272
So, after applying the primary rebate, the final tax payable on a taxable income of R500,000 would be R100,272.
Step 5: Consider the Tax Thresholds
Tax thresholds represent the income level at which you start to pay tax. If your income is below the threshold, you won’t owe any income tax. The thresholds for different age groups are:
| Age | 2025 (R) | 2024 (R) | 2023 (R) | 2022 (R) |
|---|---|---|---|---|
| Under 65 | 95 750 | 95 750 | 91 250 | 87 300 |
| 65 and older | 148 217 | 148 217 | 141 250 | 135 150 |
| 75 and older | 165 689 | 165 689 | 157 900 | 151 100 |
If your income is below these thresholds, you don’t have to pay any tax.
Additional Considerations
- Medical Tax Credits: If you pay for medical aid contributions, you may be eligible for additional tax credits. These credits directly reduce the tax you owe.
- Retirement Contributions: Contributions to retirement annuity funds are tax-deductible up to a certain limit, which can further reduce your taxable income.
- Donations: Donations to approved public benefit organizations are tax-deductible within certain limits.
Tax Planning Tips
- Keep Accurate Records: Ensure you maintain detailed records of all your income, expenses, and deductions. This will make it easier to calculate your tax accurately and take advantage of all eligible deductions and credits.
- Plan for Tax Payments: If you owe significant tax, consider making provisional tax payments throughout the year to avoid a large bill at year-end. Provisional tax is paid in two installments, with a third optional top-up payment if necessary.
- Consult a Professional: Tax calculations can become complex, especially if you have multiple income sources, significant deductions, or business income. Consulting a tax professional can help ensure that you comply with all regulations and minimize your tax liability.
