The short answer: Yes. Income from a side hustle is taxable, in addition to your salary. If it is business income, you are generally a provisional taxpayer even though you are employed, and the R30,000 exemption does not apply to you. You are taxed on the profit, which is the income minus the expenses that really belong to earning it. This is general information, so confirm your own situation with SARS or a registered tax practitioner.
Many people earn extra from selling online, weekend work, tutoring, design jobs or a small trade. It rarely feels like a business, so tax is easy to ignore. SARS treats it as income, and the earlier you set it up properly, the less likely you are to face a surprise bill.
Is side hustle income taxable?
Yes. Your salary is taxed through PAYE, which your employer deducts. Side income does not have PAYE deducted, so it is your responsibility to declare it on your tax return. It is added to your salary and taxed at your marginal rate. The deductions guide on tax deductions you are probably missing is a useful companion, and the post on reading your payslip shows what PAYE already covers.
Do you need to register as a provisional taxpayer?
This is the question that catches people. SARS says you are generally a provisional taxpayer if you earn income from carrying on a business, and a side hustle that sells goods or services to make a profit is business income. There is no separate registration for provisional tax: you must first be registered as a taxpayer with SARS (within 21 business days of becoming liable), and then you submit provisional tax returns, called IRP6, on eFiling.
The R30,000 rule is narrower than many people think. SARS says you are not a provisional taxpayer if you do not carry on a business and your taxable income from sources other than your salary, such as interest or rental income, is R30,000 or less for the year. It does not protect business income. For the 2027 tax year the tax threshold for people under 65 is R99,000, and the provisional tax guide for freelancers explains the returns and the deadlines.
How much tax would you pay?
Here is an example using the 2027 SARS tax table. You earn R25,000 a month, which is R300,000 a year, from your job. On the side you earn R3,000 a month, which is R36,000 a year, and you have R6,000 of genuine business expenses. Your profit is R30,000.
Your taxable income rises from R300,000 to R330,000. Both amounts fall in the 26% bracket, which runs from R245,101 to R383,100. The extra tax is 26% of R30,000, which is R7,800, so you keep R22,200 of the profit. This assumes you are under 65 and have no other deductions. If your total taxable income moves into a higher bracket, the part above the bracket line is taxed at the higher rate.
What can you deduct?
You can deduct expenses you incurred to earn the side income. Examples are the cost of materials or stock, software and platform fees, data used for the work, and equipment used mainly for the hustle. Personal spending, travelling to your regular job and costs that belong to your private life are not deductible. The rules are strict, so keep the invoice for every expense and be able to explain why it belongs to the hustle.
SARS also has a simplified regime for very small businesses, called turnover tax. Whether you qualify depends on your circumstances, so check with SARS before you assume it applies.
What records should you keep?
- A separate bank account for side hustle income and costs, so the figures are easy to read.
- Invoices and receipts for every expense, and a simple list of every amount you were paid.
- A monthly summary of income, expenses and profit.
- Your records for five years, which is how long SARS expects you to keep them.
It also helps to set money aside for the tax when you are paid. A simple habit is to move a fixed share of each side payment, say 20% to 30% depending on your bracket, into a separate pot. That way the bill at filing time is already saved. The post on doing a no-spend month is one way to build the habit, and budgeting on an irregular income covers uneven payments.
What if you have not declared before?
SARS receives information from many third parties, and unreported income can lead to penalties and interest. If you have not declared side income in the past, SARS has a voluntary disclosure programme that can reduce the penalties. Speak to a registered tax practitioner before you decide how to proceed.
How can Budget Hub help?
Budget Hub lets you track your income and expenses in one place, so you can see how much your side hustle brings in and what it costs. The more accurate your monthly picture is, the easier it is to set aside the tax and to fill in your return. You can also create a savings goal for your tax pot and track each contribution. The free plan includes up to three savings goals.

Yes. It is taxable income, added to your salary and taxed at your marginal rate, and you must declare it on your return.

Treat the side hustle as a small business from the first rand. Keep a separate account, save a share for tax, and keep the records for five years. That makes the return simple, and the tax a planned cost instead of a shock.
