Many small and medium-sized business owners in South Africa overpay SARS every year — not because they’re doing anything wrong, but simply because they’re unaware of the deductions they’re entitled to claim. Here are five of the most commonly missed tax deductions that could be saving your business significant money.
1. Home Office Expenses
If you run your business from home, or if you regularly work from home as a business owner or director, you may be entitled to deduct a portion of your home expenses against your business income. This includes:
- A portion of rent or bond interest
- Rates and taxes
- Electricity and water
- Home insurance
- Repairs and maintenance to the home office area
The deduction is calculated based on the floor area of your home office as a percentage of the total floor area of your home. To qualify, the space must be specifically equipped for work and regularly and exclusively used for business purposes.
Important: SARS scrutinises home office claims carefully. Make sure you have a floor plan, photographs, and documentation to support your claim.
2. Vehicle and Travel Expenses
Business travel is one of the most commonly under-claimed deductions. If you use your personal vehicle for business purposes, you can claim either:
- The actual cost method — tracking real costs like fuel, insurance, maintenance, and depreciation, and applying the business-use percentage
- The SARS deemed cost method — using SARS’s published rate per kilometre (updated annually in the budget)
A detailed logbook is essential. Without it, SARS will disallow the claim entirely. The logbook must record the date, purpose, destination, and kilometres travelled for each business trip.
3. Business-Related Training and Education
Many business owners don’t realise that training and skills development costs are fully deductible. If you or your employees attend courses, workshops, seminars, or professional development programmes that are directly related to your business operations, these costs can be claimed in full.
This includes:
- Short courses and online training
- Professional membership fees (SAIPA, SAICA, SAIT, etc.)
- Subscriptions to professional journals and industry publications
- Attendance at trade shows and industry conferences
If your business qualifies as a Small Business Corporation (SBC), you may also benefit from additional allowances under the Skills Development Levy (SDL) framework.
4. Bad Debts Written Off
If your business operates on an accrual basis and you have invoiced clients who have not paid — and you have taken reasonable steps to collect — you may be able to write off these amounts as irrecoverable bad debts and claim them as a deduction.
To qualify, the debt must have been:
- Previously included in your taxable income
- Genuinely irrecoverable after reasonable collection efforts
- Written off in your accounting records
Keep documentation of collection attempts — demand letters, attorney correspondence, or proof that the debtor is liquidated or untraceable.
5. Section 12C Accelerated Depreciation on Machinery
If your business has invested in manufacturing plant or machinery, you may qualify for accelerated depreciation under Section 12C of the Income Tax Act. Instead of writing off the asset over its useful life, you can claim:
- 40% in the year of first use
- 20% in each of the three subsequent years
This significantly reduces your taxable income in the early years of an asset’s life and improves your cash flow position. Many SME owners who invest in equipment are unaware of this allowance and simply depreciate at the standard straight-line rate, leaving money on the table.
Don’t Leave Money on the Table
Tax planning is about more than just compliance — it’s about ensuring your business only pays what it legally owes, and not a cent more. The deductions above are legitimate, SARS-approved claims that every qualifying SME should be making use of.
