Business Tax Deductions in South Africa: What Your Business Can Claim

South African businesses may deduct expenses incurred in producing taxable income under the general deduction formula in section 11(a) of the Income Tax Act 58 of 1962. For the 2024/2025 tax year, the test has three parts: the expense must be actually incurred, in the production of income, and not of a capital nature (SARS: Business Tax Deductions, 2024). Missing any of these three conditions disqualifies the expense.

Key Takeaways

The general deduction test (s11(a)): actually incurred + in production of income + not capital = deductible.

Capital assets are not immediately expensed - they are written off using wear and tear allowances under s11(e) at SARS-prescribed rates.

Penalties and fines paid to government authorities are never deductible.

Every deduction must be supported by invoices and proof of payment - SARS may request documentation during a verification.

The general deduction formula

Section 11(a) of the Income Tax Act is the starting point for most business expense deductions (legislation.gov.za). An expense qualifies if it meets all three requirements:

Actually incurred: the liability must have arisen in the relevant tax year. If you account on an accrual basis, the expense is deductible when the obligation arises - not only when the cash leaves your account.
In the production of income: there must be a direct connection between the expense and the income your business earns. General personal costs are not deductible.
Not capital in nature: recurring operational costs are revenue. One-off costs that create an asset with enduring value - a piece of equipment, an improvement to premises - are capital and deductible only through allowances, not as immediate expenses.

Common allowable deductions

Staff costs:

Salaries and wages paid to employees.
Employer contributions to pension, provident, and retirement annuity funds on behalf of employees.
Skills development levies (SDL) paid to SARS.
Staff training and development costs.

Premises:

Rent paid for business premises.
Municipal rates and taxes on business property.
Electricity, water, and business internet.
Repairs and maintenance (not structural improvements - those are capital).

Vehicle and travel:

Fuel, insurance, maintenance, and licensing for vehicles used in the business.
Where a vehicle is also used privately, only the business proportion is deductible - keep a logbook recording dates, destinations, purposes, and kilometres.

Professional and advisory fees:

Accounting, bookkeeping, and registered tax practitioner fees.
Legal fees for business operations (not capital transactions like company formation or property conveyancing).
Management and consulting fees.

Marketing and sales:

Advertising, branding, and promotional costs.
Website development costs (if treated as an ongoing expense rather than a capital website asset).
Trade show and exhibition costs.

Finance costs:

Interest on business loans and overdrafts used to fund income-producing activities.
Bank charges and merchant processing fees.

Insurance:

Business insurance premiums - public liability, business interruption, and asset cover.

Subscriptions and software:

Professional body membership fees where membership is a requirement for carrying on the trade.
Software licences and subscription services used for business.

Bad debts:

Bad debts previously included in income and written off in the current year, subject to the specific requirements in section 11(i) of the Income Tax Act.

Capital allowances - writing off assets over time

Capital assets (equipment, machinery, computers, vehicles) cannot be deducted as expenses in the year of purchase - they are capital in nature. Instead, the Income Tax Act provides specific allowances (SARS: Capital Allowances):

Section 11(e) - wear and tear: most business assets are written off at SARS-prescribed rates. Computers typically over 3 years; office furniture over 6 years; motor vehicles over 5 years. Check the current SARS rate list for the specific asset type.
Section 12C - manufacturing plant and machinery: accelerated deductions (40/20/20/20 allowance or 50/30/20 allowance) for qualifying manufacturing businesses.
Section 12B - renewable energy assets: a 100% first-year deduction for qualifying energy-efficient assets meeting SARS technical requirements.

Expenses that are not deductible

Capital expenditure: purchasing land, constructing a building, buying equipment - deductible only through capital allowances, not as an immediate expense.
Private or personal expenses: personal clothing, personal meals, personal travel - even if partly incurred during a business event.
Penalties and fines: amounts paid to SARS, municipalities, or other authorities for non-compliance are specifically excluded from the general deduction formula.
Pre-commencement expenses: in some cases, costs incurred before a business starts trading require special consideration under section 11A.

Home office deductions

If you run a business from home, a proportion of home running costs attributable to the dedicated business space is deductible (SARS: Home Office Expenses). Calculate the proportion using office floor area as a fraction of total home floor area. Only the business-use portion of rent or bond interest, rates, electricity, and maintenance is deductible - the room must be used exclusively and regularly for business.

Records required to support deductions

Keep the following for at least five years:

Invoices and receipts for all expenses claimed.
Bank statements showing payment.
Contracts and agreements for recurring costs.
Logbooks for vehicle expenses.
Payroll records for staff costs.
Asset registers and depreciation schedules for capital allowances.

Frequently Asked Questions

Can a business deduct the full purchase price of a laptop or equipment in the year of purchase?

No. Capital assets are not immediately deductible as expenses under section 11(a). The cost is written off over time through wear and tear allowances under section 11(e), using SARS-prescribed rates. Computers are typically written off over three years using the specified rate. Some assets may qualify for accelerated allowances - check the specific SARS list for your asset type.

Are penalties and fines paid to government authorities deductible?

No. Amounts paid as penalties, fines, or levies to government authorities for non-compliance are excluded from the general deduction formula. This applies to SARS interest and penalties, municipal fines, and similar regulatory charges. Only legitimate business costs incurred in the normal course of operations qualify.

How do I apportion vehicle costs between business and personal use?

Keep a logbook recording each business trip - the date, destination, purpose, and kilometres travelled. At year-end, calculate business kilometres as a percentage of total kilometres driven. Apply that percentage to total vehicle costs (fuel, insurance, maintenance, depreciation allowance). SARS regularly challenges vehicle expense claims without a logbook.

Can a sole proprietor deduct their own salary?

No. A sole proprietor and their business are legally the same entity - drawings are not a deductible expense. The entire net profit (income minus allowable business expenses) is included in the sole proprietor’s personal taxable income. Deducting a “salary to self” would amount to deducting the same amount twice.
