Provisional tax — how it works
If your taxable income from sources other than employment exceeds R30 000/year, you become a provisional taxpayer. Instead of a surprise bill at filing, you pay in two instalments:
First provisional return
By 31 August (6 months into the tax year)
Estimate your full-year income. Pay 50% of your estimated annual tax (less any PAYE already withheld from employment income).
Second provisional return
By 28 February (tax year-end)
Update your income estimate. Pay the remaining balance — any shortfall from the first payment is settled here.
Final annual return (ITR12)
After the tax year ends (eFiling deadline: November)
File your full ITR12. If you overpaid provisional tax, SARS refunds the difference. If you underpaid, you pay the shortfall plus interest.
When you need to register for VAT
Compulsory registration
R1m+/year
Once taxable turnover exceeds R1 000 000 in any 12-month period, you must register within 21 days. Applies to all business types — sole proprietor, company, trust.
Voluntary registration
R50k+/year
You may voluntarily register from R50,000/year. Useful if your clients are VAT-registered businesses — they can reclaim the VAT you charge, and you can reclaim input VAT on your business expenses.
Allowable deductions on side income
SARS allows deductions for expenses incurred in the production of the income (Income Tax Act s11). You cannot deduct personal expenses, and mixed-use items must be apportioned.
✓ Home office expenses
If you work from home exclusively for your side hustle, you can deduct a proportionate share of rent, electricity, and rates. SARS requires a dedicated workspace — you cannot deduct the kitchen table.
✓ Equipment and tools
Laptops, cameras, software, tools, and equipment used for the business. If used partly for personal purposes, only the business-use portion is deductible.
✓ Data, phone, and internet
The business-use portion of your phone and internet costs. Keep records of business vs personal use — SARS accepts a reasonable estimate if you can justify it.
✓ Vehicle costs (actual or deemed)
If you drive for your side hustle, you can claim actual costs (fuel, maintenance, insurance) × business km ÷ total km, or use SARS's deemed-cost tables per km. Keep a logbook.
✓ Professional services
Accounting, legal, and tax advice fees directly related to earning the income are fully deductible.
✓ Bank charges and payment fees
Business bank account fees, PayFast/PayGate processing fees, and similar transaction costs attributable to the side hustle.
Frequently asked questions
Do I need to declare side income to SARS?
Yes. All income earned in South Africa — whether from employment, freelance work, rentals, or gig platforms — must be declared in your annual tax return (ITR12). SARS has access to third-party data from banks, payment processors, and Airbnb/Uber. Undeclared income is taxable and carries penalties and interest.
What is provisional tax and does it apply to me?
Provisional tax (IRP6) applies if you have taxable income other than employment income (salary) that exceeds R30 000 per year. As a side hustler, you submit two provisional returns per year — by 31 August (6 months into the tax year) and by 28 February (year-end) — and pay estimated tax on your side income. This prevents a large lump sum tax bill after you file your ITR12.
When do I need to register for VAT on my side hustle?
You must register for VAT when your taxable turnover (not profit — revenue) exceeds R1 000 000 in any 12-month period. You may voluntarily register once you exceed R50,000/year in turnover. VAT registration means charging 15% VAT on invoices, filing bimonthly VAT returns, and collecting VAT on behalf of SARS — but you can also claim back input VAT on business expenses.
Can I register as a sole proprietor or company for my side hustle?
You don't need to register a company for a side hustle — you can operate as a sole proprietor under your own name. Income is declared in your personal ITR12. A private company (Pty Ltd) can offer liability protection and tax planning flexibility, but it adds admin (annual returns, company tax at 27%, dividends tax). For most side hustles under R500k/year, sole proprietor is simpler and cheaper.
How is rental income taxed in South Africa?
Rental income is declared in your ITR12 and taxed at your marginal PAYE rate, the same as other income. You can deduct expenses directly related to the rental: bond interest, rates and taxes, maintenance, insurance, and agent fees. The net rental profit (income minus allowable expenses) is added to your other income and taxed accordingly.
