How to Track Business Expenses for SARS in South Africa (2026 Guide)

To claim a business expense from SARS it must be actually incurred in earning your income and not be capital in nature, and you have to keep the supporting record for five years. The practical answer is to capture each expense the day it happens, with the tax invoice attached, so filing season is a report rather than a reconstruction.

That is the whole discipline in two sentences. The rest of this guide is what actually qualifies, the records SARS expects, and a simple system that keeps you ready instead of scrambling in October.

What business expenses can you claim from SARS?

South African tax law does not hand you a tidy shopping list. It hands you a test. The general deduction formula in section 11(a) of the Income Tax Act allows you to deduct expenditure and losses actually incurred in the production of income, as long as they are not of a capital nature and the income is not exempt. Read plainly, that is three questions for every expense:

• Was it actually incurred? Real money you were genuinely obliged to pay, not an estimate or a plan.
• Was it in the production of income? It has to be connected to earning your business income, not a private cost wearing a business label.
• Is it revenue, not capital? Day-to-day running costs are deducted in full. A lasting asset is capital, and you claim it over time through wear-and-tear allowances instead.

Get those three right and you are on solid ground. Most disputes with SARS are not about exotic rules. They are about an expense that fails one of these three tests, or a record that cannot prove it passed them.

Common deductible expenses for a South African small business

Within that test, the everyday costs of running a business are usually claimable. Common examples include:

• Rent for business premises and related utilities
• Salaries, wages and the contributions you pay for staff
• Stock, raw materials and direct cost of sales
• Business phone, data and internet
• Accounting, bookkeeping and professional fees
• Bank charges on the business account
• Business insurance
• Marketing, advertising and website costs
• Business travel and vehicle running costs, apportioned to business use
• Repairs and maintenance to business assets

Two cautions sit on top of this list. Anything used for both business and private life, a car or a home office, must be split honestly and only the business portion claimed. And a genuine asset, a laptop or machinery, is capital, so it is written off through allowances rather than deducted all at once. When in doubt, keep the record and ask an accountant which side of the line it falls on.

The rule that catches people out: no record, no deduction

An expense you cannot prove is an expense you cannot claim. Section 29 of the Tax Administration Act requires you to keep the records, books and documents that support your return for five years from the date you submit it, and longer if SARS has opened an audit or query that is not yet closed.

For most expenses the document that matters is a valid tax invoice, not a card slip or a bank line. A card statement shows that money left your account. It does not show what you bought or that the supplier charged VAT. We set out exactly what a compliant invoice must contain in tax invoice requirements in South Africa. If you plan to claim it, keep the invoice behind it.

How to track business expenses so filing is not a scramble

The businesses that file calmly are not the ones with the best accountant. They are the ones who captured as they went. Here is a system that takes minutes a week.

1. Separate the money. Run every business cost through a dedicated business bank account. The moment personal and business money mix, every claim becomes an argument you have with yourself at year end.
2. Capture at the point of spend. Photograph or save the tax invoice the day you get it and log the expense while you still remember what it was for. A receipt captured today costs nothing. A receipt reconstructed in October costs an afternoon, and often the deduction.
3. Categorise consistently. Use the same expense categories all year so your totals line up with the fields on your return. Guessing categories once a year is how real deductions get missed.
4. Reconcile monthly, not annually. Match your logged expenses to the bank account once a month. Twelve small reconciliations beat one that eats a weekend and hides mistakes.
5. Store it where it survives. Keep the records digitally and backed up for the full five years. Shoeboxes fade, phones get lost, and SARS accepts neither as an excuse.

None of this is difficult. It is just admin, and admin is exactly the kind of quiet, repeated work that bleeds a small business when it is left to pile up, as we covered in the real cost of manual admin. The same instinct that makes owners too busy to grow is the one that leaves expense tracking for later. Capturing as you go is the cheapest habit in business.

Why this matters right now: filing season 2026 is open

This is not a January problem. The 2026 filing season is already running. SARS ran auto-assessments from 1 to 12 July 2026, and the general filing period is open from 13 July to 23 October 2026 for non-provisional taxpayers, with provisional taxpayers having until 22 January 2027. If your records are in order, filing is a short job. If they are not, you are reconstructing a year of spending against a deadline.

Good expense tracking is really just one habit inside a wider one: knowing where your time and money actually go, before a deadline or a tax bill forces you to look. That is the same reason we push owners to map their operations early, the theme of the hidden cost of starting a business, and to capture work as it happens, the way a good time tracking habit does for hours.

Frequently Asked Questions

What business expenses can I claim from SARS?
You can claim expenses actually incurred in earning your business income that are not capital in nature, such as rent, salaries, stock, professional fees, bank charges, insurance and business travel. Private costs, or the private portion of a shared cost, cannot be claimed.

How long must I keep records for SARS?
Five years from the date you submit the relevant return, under section 29 of the Tax Administration Act. If SARS has notified you of an audit or investigation, keep the records until that process is fully concluded, even if it runs past five years.

Do I need a tax invoice to claim an expense?
For most business expenses, yes. A valid tax invoice proves what you bought and the VAT charged, which a card slip or bank statement does not. Without the supporting document, SARS can disallow the deduction.

Can I claim home office expenses in South Africa?
Sometimes, if you meet SARS's conditions, such as a dedicated area used regularly and exclusively for work. Only the business portion is claimable, usually calculated on floor area, and the rules are strict, so confirm your position with an accountant before claiming.

When is the 2026 SARS tax filing deadline?
Non-provisional taxpayers have until 23 October 2026, and provisional taxpayers until 22 January 2027. The season opened on 1 July 2026 with auto-assessments, followed by general filing from 13 July 2026.

Track the work, not just the receipts

Expense records are one symptom of a bigger question: does your business capture what it does as it happens, or reconstruct it under pressure later? A Business Autopsy looks at exactly where that reconstruction is costing you time and money, expenses included, and shows what to fix first. Book a discovery call if you would rather talk it through.
