Key takeaways

• Small businesses in South Africa can deduct operating costs, travel, home office costs, employee expenses, and other business expenses from taxable income. They can also claim wear and tear for most movable capital assets.
• To calculate the tax on business profits, sole proprietors and partners should use their individual income tax rates. Corporations face a 27% rate, while small business corporations (SBCs) are taxed at tiered rates from 0 to 27%.
• If you're audited or selected for a review, SARS requires invoices, receipts, logbooks, and depreciation schedules for every claim, and you need to keep records for five years.
• Businesses with annual turnover under R2.3 million can opt for Turnover Tax, a simpler system that replaces income tax, provisional tax, capital gains tax, and dividends tax. Instead, you just pay a much lower tax rate on your top-line revenue.

What is a tax deduction?

A tax deduction is an amount you subtract from your gross income before calculating your tax liability. Businesses can deduct legitimate business expenses from their revenue when they file their tax returns. The more qualifying deductions you claim, the lower your taxable income, and the less tax you'll owe.

For an expense to qualify as a deduction, it must meet the "production of income" test set out in Section 11(a) of the Income Tax Act. In simple terms, the expense must be incurred in the course of carrying on your trade and for the purpose of earning business income. Personal expenses, even if paid from a business account, don't qualify.

Businesses can also use tax credits to reduce their tax liability, but they work differently from deductions. While a deduction reduces the income on which tax is calculated, a credit directly reduces the amount of tax you pay. In South Africa, most business tax relief comes through deductions rather than credits – so it's critical to understand what you can claim and how.

Who qualifies for business tax deductions in South Africa?

If you're earning business income in South Africa and registered with the South African Revenue Service (SARS), you're likely entitled to claim business deductions. The structure of your business determines how those deductions are applied and what tax rates you'll pay.

Sole proprietors and freelancers

As a self-employed individual, you can claim expenses directly related to earning your business income. Your business profits are added to your personal income and taxed at the applicable individual income tax rates. You'll report your deductions on your ITR12 return.

Partnerships

Partners split up their share of the business's income and expenses, based on their partnership agreement. Then, they report their income and deductions on their ITR12 return and pay tax accordingly.

Companies and close corporations

If your business is registered as a company or close corporation, it's taxed as a separate legal entity. You'll deduct allowable expenses from your company's gross income before applying the standard corporate tax rate of 27% – small business corporations qualify for different rates. Companies file an ITR14 return with SARS, which is completely separate from the owners' individual ITR12 returns.

Small Business Corporations (SBCs)

SBCs benefit from reduced, progressive tax rates that are significantly lower than the flat 27% corporate rate. To qualify as an SBC for the 2026/2027 year of assessment (1 March 2026 to 28 February 2027), your business must meet specific requirements: all shareholders must be natural persons, your gross income can't exceed R20 million, and you may need to meet other criteria related to passive income or outside shares.

You don't have to apply. When you file your ITR14, SARS will use the info you provide on the form to decide if you're eligible. If so, they'll apply the SBC tax brackets for 2026/2027:

• 0%: on the first R99,000 of taxable income
• 7%: on taxable income from R99,001 to R365,000
• 21%: on taxable income from R365,001 to R550,000
• 27%: on taxable income above R550,000

SBCs also enjoy accelerated depreciation allowances, including a 100% write-off on manufacturing assets in the year of purchase. These benefits make the SBC structure one of the most tax-efficient options for growing businesses in South Africa.

Common tax-deductible business expenses in South Africa

Understanding which expenses qualify as deductions is the first step to reducing your tax bill. Here's a breakdown of the most common categories.

Operating expenses

Your day-to-day running costs are generally fully deductible. These include:

• rent and utilities: office or retail space rental, electricity, water, and property rates
• office supplies: stationery, printing, and consumables
• insurance premiums: business insurance, professional indemnity, and asset cover
• marketing and advertising: digital campaigns, print media, and website costs
• telecommunications: business phone lines, mobile contracts, and internet
• accounting and legal fees: professional services related to running your business

Employee costs

If you employ staff, their costs represent some of your largest deductible expenses:

• salaries, wages, bonuses, and commissions: all remuneration paid to employees
• UIF contributions: your share of Unemployment Insurance Fund payments
• SDL contributions: Skills Development Levy payments
• training and development: costs incurred for employee upskilling and professional development programmes

Travel and vehicle expenses

Business travel is deductible, but you need proper records to support your claims. SARS lets you claim wear and tear for delivery vehicles based on their useful life, and if you use a vehicle for both personal and business use, you can claim a deduction based on its portion of business use. You can also deduct accommodation and subsistence for local and foreign travel as long as it's for business purposes.

Keeping accurate records, including logbooks and repair receipts, throughout the year is critical. Without them, SARS may disallow your vehicle or travel expense claims entirely.

Capital expenses and depreciation

Capital assets like equipment, machinery, and vehicles aren't deducted in full immediately. Instead, you claim a wear and tear allowance that spreads the deduction over the asset's useful life.

There's an important exception: assets costing less than R7,000 can be written off in full in the year of purchase. This "small asset rule" applies to items like laptops, small office furniture, and tools. SARS also lets SBCs claim accelerated depreciation – they can write off 100% of manufacturing equipment in the year of purchase and 50% of most other assets.

What if you convert a personal asset into business use? Then, you can claim wear and tear based on its cost or value in light of its remaining useful life.

Home office expenses

If you run your business from home, you can claim a proportional deduction for your home office expenses. To qualify, the space must be used regularly and exclusively for business purposes, and it may need to meet other requirements, such as being equipped for your trade – for example, a desk if you do office work.

The calculation is straightforward. Determine the floor area of your home office as a percentage of your home's total floor area, then apply that percentage to:

• bond interest or rent: the proportional share of your monthly payment
• utilities: electricity, water, and rates for the home
• insurance and repairs: home insurance and maintenance costs related to the office space

Be conservative with your home office claims, or consult with a tax expert. SARS scrutinises these deductions closely, and overclaiming is a common audit trigger.

Professional fees and subscriptions

You can deduct fees and subscriptions that are directly related to your trade:

• industry body memberships: professional associations relevant to your business
• professional registrations: mandatory registrations required to practise in your field
• legal and accounting fees: ongoing advisory services, tax preparation, and audit fees

Business expenses you cannot deduct

Not every business-related cost qualifies as a tax deduction. Understanding the boundaries helps you avoid SARS disputes and potential penalties.

• Personal living expenses: Groceries, personal clothing, and household costs are never deductible, even if paid from a business account.
• Fines and penalties: Traffic fines, SARS penalties, and other regulatory fines can't be deducted.
• Entertainment: Business entertainment has limited deductibility. General client entertainment is often disallowed unless it's directly linked to earning income.
• Loan repayments: While interest on a business loan is deductible, the capital portion of your repayments isn’t.
• School fees and personal education: Education costs for yourself or your family don't qualify unless they're directly related to your current trade.

The turnover tax option for small businesses

If your business has an annual turnover of R2.3 million or less, you may qualify for the turnover tax system. This simplified tax option replaces income tax, VAT, provisional tax, capital gains tax, and dividends tax with a single tax calculated on your turnover.

Turnover tax offers real simplicity. You file a single annual return, and because the tax is based on turnover rather than profit, record-keeping requirements are less demanding. You don't need to track and categorise every individual expense.

However, there's a trade-off. Under turnover tax, you can't claim the business expense deductions outlined in this guide. If your business has high operating costs relative to turnover, you might pay more tax under this system than you would under the standard income tax regime. But crunch the numbers to be sure. Because the turnover tax rates are so much lower than the standard corporate and SBC tax rates, most businesses pay less if they qualify.

Turnover tax suits businesses with relatively low revenue, modest expenses, and straightforward operations. If your deductions are significant, sticking with the standard tax system and claiming every qualifying expense may be the better option. An accountant or tax practitioner can help you model both scenarios using your actual figures.

How to claim tax deductions with SARS

Claiming your deductions doesn't have to be complicated. Here's the process.

1. Register for income tax. If you haven't already, register your business with SARS via eFiling. Sole proprietors register as individuals; companies register separately.
2. Keep records throughout the year. Track every deductible expense as it occurs. Store invoices, receipts, bank statements, logbooks, and depreciation schedules in an organised system.
3. Complete your tax return. Companies and close corporations file an ITR14. Sole proprietors, freelancers, and partners file an ITR12 and include their business income and expenses under the trade section.
4. Submit supporting documents if requested. SARS may request verification of specific deductions. Having your records in order means you can respond quickly and confidently.

Your record-keeping needs to meet SARS standards. You're required to retain all business tax records for five years from the date of your last submission. Required documents include invoices, receipts, bank statements, vehicle logbooks, asset registers, and depreciation schedules.

A cloud-based accounting system that captures and categorises expenses in real time saves hours of manual admin at tax time. It also makes it far easier to respond to SARS queries, especially if your return is audited.

Common mistakes when claiming business tax deductions

Even experienced business owners make errors with their tax deductions. Avoiding these common pitfalls can save you from penalties and unnecessary audits.

• Claiming personal expenses as business costs: This is the most frequent mistake. Make sure every deduction relates directly to your trade.
• Inadequate documentation: A claim without supporting records is a claim SARS can reject. Keep every invoice, receipt, and logbook entry.
• Missing provisional tax deadlines: If you're a provisional taxpayer, late payments attract interest and penalties. Mark your payment dates in your calendar and set reminders.
• Not separating business and personal finances: Mixing accounts makes it difficult to track deductions accurately and creates confusion during an audit. Use a dedicated business bank account to keep your expenses organised.
• Overclaiming home office deductions: Only claim the proportional space you use exclusively for business. SARS flags disproportionate home office claims.

FAQs on business tax deductions in South Africa

Here are answers to some of the most common questions about business tax deductions in South Africa.

What business expenses are tax-deductible in South Africa?

Any expense that passes the Section 11(a) "production of income" test is generally deductible. The key question to ask before claiming any expense is whether you incurred it directly in the course of earning your business income – if you didn't, it's not a business deduction.

What is the tax exemption for small businesses in South Africa?

The SBC 0% bracket isn't a formal exemption from registration or filing, nor is the 0% bracket for businesses that file turnover tax. You still need to register with SARS and submit annual returns; the 0% rate simply means no tax is owed on that portion of your taxable income or on your revenue if you're dealing with turnover tax.

Can you claim your home office as a tax deduction?

Yes, but be aware that claiming a home office deduction may affect your capital gains tax (CGT) exemption if you later sell the property. The portion claimed as a home office could be excluded from the primary residence CGT exclusion.

How long do you need to keep tax records in South Africa?

SARS requires you to keep records for five years, but during audits, SARS accepts both physical and digital formats, so scanned receipts and cloud backups count. If SARS audits you and your records are missing, your claims may be disallowed entirely, potentially creating a significant tax liability.

What’s the difference between SBC tax and standard corporate tax?

Standard corporate tax applies a flat rate of 27% to all taxable income – that's revenue minus deductible business expenses and depreciation allowances. SBC tax uses progressive brackets starting at 0% on the first R99,000 and climbing to 7%, 21%, and finally to 27% on taxable income over $550,001 as of 2021. That means smaller profits are taxed at significantly lower rates. SBCs must meet specific criteria, including having natural person shareholders and an annual gross income of R20 million or less.
