What business expenses are tax deductible in South Africa?
Every rand you spend running your business can lower the tax you pay — but only if it passes the SARS test and you can prove it. Here's the plain-English list of what you can deduct, what you can't, and the records that keep your claims safe.
- An expense is deductible if it's incurred in the production of income and isn't private or capital in nature.
- Rent, salaries, stock, fuel, phone, insurance, fees and marketing are the everyday deductions.
- Mixed personal-and-business costs must be apportioned to the business share only.
- No receipt, no deduction — SARS can disallow any claim you can't support.
The test SARS actually applies
South African income tax doesn't give you a fixed menu of "allowed" expenses. Instead, the Income Tax Act lets you deduct amounts that are incurred in the production of income and are not of a capital nature — and that aren't private, domestic or specifically blocked. That's the general deduction formula, and almost every legitimate business cost fits it.
In practice, ask three questions about any expense:
- Was it for the business? Spending to earn your trading income qualifies; personal spending doesn't.
- Is it a running cost, not an asset? Day-to-day costs are deductible in full; big capital items (a vehicle, machinery, a laptop) are usually claimed over time as wear-and-tear / capital allowances instead.
- Can you prove it? You need a valid receipt, tax invoice or record for the amount.
Common deductible business expenses
For most small businesses, sole proprietors and freelancers in South Africa, the everyday deductions look like this:
| Category | Examples |
|---|---|
| Premises | Rent, rates, water and electricity, office cleaning, security |
| People | Salaries and wages, UIF, contributions, casual labour, subcontractors |
| Stock & materials | Goods for resale, raw materials, packaging, consumables |
| Travel & vehicle | Fuel, oil, maintenance, licensing and insurance for business travel (log your business kilometres) |
| Communications | Cellphone, data, fibre, landline, hosting and software subscriptions |
| Professional fees | Accounting, bookkeeping, legal, consulting and bank charges |
| Marketing | Advertising, website, social media, printing, signage |
| Protection | Business insurance, tools, protective clothing, repairs and maintenance |
The home-office deduction
If you work mainly from home, you may be able to deduct a portion of your home-office costs — rent or bond interest, rates, electricity, cleaning and repairs — based on the floor area of the dedicated work space versus your whole home. SARS sets specific conditions: the space must be used regularly and exclusively for your trade and be specifically equipped for it. Keep the floor-area calculation and the underlying bills on file, because this is a frequently audited claim.
The deductions people lose aren't the big ones — it's the R80 parking, the R150 hardware run, the R45 stationery slip that never made it into the books. They're individually tiny but add up to thousands a year. The fix is capturing each one the moment it happens, not at year-end.
What you can't deduct
- Private and domestic expenses — groceries, personal clothing, your own medical bills.
- Capital items — claimed via wear-and-tear allowances over their useful life, not deducted in full upfront.
- Fines and penalties — traffic fines, SARS penalties and the like.
- The private portion of any mixed-use cost — apportion your cellphone, car and home office to the business share only.
- Entertainment VAT — note the VAT on entertainment is blocked even where the cost itself is deductible for income tax (see our VAT guide).
Proof is the whole game
A deduction is only as good as the record behind it. SARS requires you to keep supporting documents for five years, and on audit the burden is on you to produce them. A claim with no receipt is the easiest thing in the world for an assessor to disallow.
This is exactly where most small businesses leak money: the expenses are real and deductible, but the slips faded, got lost, or never got recorded. Capturing every receipt as it happens — and filing it somewhere searchable — turns tax time from a panic into a print-out.
