South Africa Side Income Tax Calculator
Calculate the additional tax on your side income or second job earnings in South Africa.
Your main salary or employment income before side income
Side income in South Africa is added to your total taxable income and taxed at your marginal rate.
If your side income is from a trade or business, you can deduct related expenses (internet, equipment, supplies, etc.).
If you earn side income not subject to PAYE, you may need to register as a provisional taxpayer with SARS.
Keep records of all side income and expenses for at least 5 years as SARS may audit.
How SARS taxes income from side hustles, freelance work, and secondary employment
Do I need to pay tax on my side income?
Yes. All income is taxable in South Africa, including side hustle income. Whether you sell products online, do freelance work, tutor, drive for Uber, or rent out a room, the income must be declared to SARS. Side income is added to your main salary and taxed at your marginal rate. If your salary puts you in the 31% bracket, your side income is also taxed at 31% or higher.
How much side income can I earn before paying tax?
There is no separate threshold for side income. If you already earn a salary, every rand of side income is taxable. However, if your side income is your only income, the tax-free threshold is R95,750 per year (under 65). You must register as a provisional taxpayer if your side income exceeds R30,000 per year and is not subject to PAYE withholding.
What expenses can I deduct from side income?
Expenses directly related to earning your side income are deductible. Uber drivers can deduct petrol, vehicle maintenance, and insurance. Freelance designers can deduct software subscriptions, equipment, and internet costs. Airbnb hosts can deduct cleaning, utilities, and a portion of rates. Keep all receipts — SARS may request proof during an audit.
Do I need to register as a provisional taxpayer?
Yes, if your side income exceeds R30,000 per year and is not subject to PAYE withholding. Provisional taxpayers make two payments per year: 31 August and 28 February. Your first provisional payment must estimate your total annual income from all sources. If your salary is R400,000 and side income is R80,000, base your provisional tax on R480,000.
What if my employer does not know about my side income?
You do not need to tell your employer about side income (check your contract for any restrictions). However, SARS must know about all your income. Your employer only withholds PAYE on your salary. The additional tax on side income is your responsibility through provisional tax payments or when you file your annual ITR12 return.
Can my side income push me into a higher tax bracket?
Yes. Side income is added on top of your salary. If your salary is R350,000 (in the 31% bracket) and you earn R50,000 from a side hustle, your total is R400,000. The side income falls partly in the 31% bracket and partly in the 36% bracket (which starts at R370,500). You owe extra tax on the side income at these higher rates.
Do I need to register for VAT on side income?
Only if your total taxable supplies (from all sources, not just side income) exceed R1 million in 12 months. Most side hustles fall well below this threshold. If you are already VAT-registered for your main business, your side income may also need to be included in your VAT calculations — consult a tax practitioner for your specific situation.
