Tax Deductions Every South African Business Owner Should Know

A cautious, records-first guide to common South African business deductions and the proof needed before claiming them.

Last updated: 20 May 2026

Key takeaways
  • A business expense is not deductible just because money was spent; it must connect to income-producing activity and be properly supported.
  • VAT input tax, income tax deductions, capital allowances, and private-use adjustments are separate checks.
  • Keep invoices, bank proof, contracts, apportionment notes, and working papers for each claim.

Common categories to review

Trading stock and cost of sales.

Rent, utilities, software, accounting fees, insurance, and bank charges.

Employee remuneration, payroll costs, and training where properly documented.

Motor vehicle, travel, cellphone, and home-office costs where business use can be shown.

Capital assets and wear-and-tear allowances where the asset is used in the business.

Claims that need extra care

Mixed private and business expenses need a reasonable apportionment.

Entertainment, shareholder costs, penalties, and personal expenses are high-risk areas.

VAT vendors must separately check whether input VAT may be claimed and whether the tax invoice is valid.

Working file checklist

Supplier invoice or contract.

Bank proof of payment.

Business reason for the expense.

Tax period and VAT period allocation.

Apportionment calculation where there is private use.

Records to keep

  • SARS notices, assessments, eFiling confirmations, and statements of account.
  • Invoices, contracts, bank statements, payroll records, VAT reports, or calculations that support the position.
  • A short note showing the tax year, rule checked, source used, and reason for the treatment.

FAQ

Can I deduct every business bank transaction?

No. The amount must be connected to business income, not capital or private in nature unless a specific rule allows treatment.

Is a card slip enough proof?

Usually not on its own. Keep the invoice or supporting document that shows what was bought and why it relates to the business.

Can I rely on this guide for a final tax decision?

No. This guide is educational. Verify current SARS guidance and get professional advice where the amount is material or the facts are complex.
