What is small business tax in South Africa?

Small business tax in South Africa refers to the taxes your business must pay to the South African Revenue Service (SARS), the country's tax authority. The system offers several pathways, and the one you follow depends on how your business is structured and how much it earns.

At the standard level, companies pay a flat corporate income tax rate of 27% on taxable income. But SARS recognises that smaller businesses need room to grow. That's why two preferential tax regimes exist specifically for qualifying small businesses.

The first is Small Business Corporation (SBC) tax, a graduated rate structure that taxes your first R99,000 at 0% and applies progressively higher rates as income increases. It's available to qualifying companies, close corporations (CCs), and co-operatives. The second is Turnover Tax, a simplified system designed for micro businesses where you pay tax on gross turnover rather than taxable income, which means you don't need to calculate deductions or capital gains separately.

Understanding which regime applies to you is the first step toward paying only what you owe and keeping more of what you earn.

How SARS defines a small business

SARS uses specific criteria to determine whether your business qualifies for preferential tax treatment. The definition varies depending on which regime you're applying for.

For the SBC regime, your business must meet all of the following requirements:

• Be a private company (Pty Ltd), close corporation (CC), or co-operative
• Have only natural persons as shareholders or members (not trusts or other companies)
• Have gross income of R20 million or less per year
• Not be a personal service provider
• Not derive more than 20% of gross receipts from investment income, rental from letting fixed property or personal service activities

For Turnover Tax, the threshold is simpler. Your business must have an annual turnover of R2.3 million or less, following the increase announced in the 2026 Budget. This was previously capped at R1 million.

Types of business structures and how they're taxed

The tax you pay depends heavily on how your business is legally structured. South Africa recognises several business forms, and each one is taxed differently. Here's how the main structures work.

A sole proprietor operates as an individual. Your business income is added to your personal income, and you pay tax at personal income tax rates, which range from 18% to 45% depending on your total taxable income. There's no separate business tax return; everything flows through your personal return filed with SARS.

A partnership works similarly. Each partner is taxed individually on their share of the partnership's profits, again at personal income tax rates. The partnership itself doesn't pay tax.

A private company (Pty Ltd) is a separate legal entity. It pays corporate income tax at the standard 27% rate, unless it qualifies as an SBC, in which case graduated rates apply. This is the most common structure for small businesses that want limited liability and potential tax savings.

A close corporation (CC) is taxed identically to a Pty Ltd. Although SARS no longer allows new CC registrations, existing CCs continue to operate and can still qualify for SBC rates.

Sole proprietor vs company: Tax implications

If you're earning above a certain level, incorporating as a Pty Ltd could save you tax. As a sole proprietor, income above R887,000 is taxed at 41% or higher (2026/2027 tax year). A qualifying SBC company, by contrast, pays a maximum of 27% on income above R550,000.

The trade-off is complexity. A company requires separate tax returns, annual financial statements and compliance with the Companies Act. For many growing businesses, the tax savings outweigh the extra admin, but it's worth discussing with your accountant before making the switch.

Small Business Corporation (SBC) tax rates

The SBC regime is one of the most valuable tax incentives available to South African small businesses. If your company qualifies, you pay 0% tax on the first R99,000 of taxable income, which means significant savings compared to the flat 27% corporate rate.

Here are the SBC tax rates for the 2026/2027 tax year (years of assessment ending between 1 April 2026 and 31 March 2027):

• R0 to R99,000: 0% (no tax payable)
• R99,001 to R365,000: 7% of the amount above R99,000
• R365,001 to R550,000: R18,620 plus 21% of the amount above R365,000
• R550,001 and above: R57,470 plus 27% of the amount above R550,000

To put this in perspective, a qualifying SBC with R500,000 in taxable income would pay roughly R46,970 in tax. A non-qualifying company earning the same amount would pay R135,000 at the flat 27% rate. That's a difference of over R88,000.

Beyond lower rates, SBC-qualifying businesses also benefit from accelerated depreciation on manufacturing assets and an immediate write-off for assets used in the business that cost less than R7,000 each.

SBC qualification requirements

Not every small business qualifies for SBC rates. SARS applies strict criteria, and failing to meet even one of them disqualifies your business for that tax year.

Your business must satisfy all of these conditions:

• have only natural persons as shareholders or members (not trusts, companies or other entities)
• have gross income of R20 million or less for the year of assessment
• not carry on a personal service, as defined in paragraph 1 of the 4th Schedule to the Income Tax Act
• not derive more than 20% of total receipts and accruals (excluding capital gains) from investment income, rental from letting fixed property or remuneration from a connected person for personal services rendered

If your business structure changes during the year, for example if a trust acquires shares, you'll lose SBC status for that entire year of assessment. It's important to check your eligibility annually.

Turnover Tax for micro businesses

Turnover Tax is a simplified tax system designed for the smallest businesses in South Africa. Instead of calculating taxable income with deductions and capital gains, you simply pay a percentage of your total annual turnover. It replaces Income Tax, Provisional Tax, Capital Gains Tax (CGT), and Dividends Tax in a single, streamlined return.

The 2026 Budget brought significant changes to this system. The qualifying threshold increased from R1 million to R2.3 million, and the tax-free threshold rose to R600,000. This means many more micro businesses can now use this simpler system, and those already on it keep more of their earnings.

2026 Turnover Tax rates

The updated rates for the 2026/2027 tax year reflect the expanded thresholds announced in the Budget.

Here are the current Turnover Tax rates:

• R0 to R600,000: 0% (no tax payable)
• R600,001 to R950,000: 1% of the amount above R600,000
• R950,001 to R1,400,000: R3,500 plus 2% of the amount above R950,000
• R1,400,001 and above: R12,500 plus 3% of the amount above R1,400,000

Turnover Tax is available to sole proprietors, partnerships, companies, CCs, and co-operatives, provided the business's qualifying turnover doesn't exceed R2.3 million. However, certain types of businesses are excluded, including professional services regulated by law, labour brokers, and businesses with investment income exceeding prescribed limits.

To register, you submit an application to SARS via eFiling. You can switch from the standard tax system to Turnover Tax at the start of a new year of assessment.

SBC vs Turnover Tax: Which is right for your business?

Choosing between SBC and Turnover Tax isn't a one-size-fits-all decision. The right option depends on your business's turnover, expenses, and growth plans. Here's a practical way to think about it.

Choose SBC if your business has high operating expenses. Because SBC tax is calculated on taxable income (turnover minus deductions), you benefit from claiming expenses like salaries, rent, equipment, and professional fees. The more deductions you have, the lower your tax bill.

Choose Turnover Tax if your expenses are low relative to your turnover and your annual turnover is under R2.3 million. Since tax is based on total turnover with no deductions, this system works best for businesses with high profit margins and minimal costs, such as consultants, freelancers or online service providers.

Here's a worked example. Imagine your business has R800,000 in annual turnover and R300,000 in deductible expenses.

Under Turnover Tax, you'd pay tax on the full R800,000 turnover. Using the 2026/2027 rates, that comes to 1% of R200,000 (the portion above R600,000), which equals R2,000.

Under SBC, your taxable income would be R500,000 (R800,000 minus R300,000 in deductions). Using the 2026/2027 SBC rates, your tax would be R18,620 plus 21% of R135,000 (the portion above R365,000), totalling R46,970.

In this example, Turnover Tax saves you R44,970. But if your expenses were R650,000, your SBC taxable income would be R150,000, and your tax would be just R3,570 under SBC rates, making SBC the cheaper option.

The key factors to consider are:

• Your profit margin: low margins favour SBC; high margins favour Turnover Tax
• Your turnover level: Turnover Tax is only available up to R2.3 million
• Your growth trajectory: If you expect rapid turnover growth, you may outgrow Turnover Tax quickly.
• Your record-keeping preference: Turnover Tax requires less detailed bookkeeping.

Tax deductions and allowances for small businesses

If you're on the standard corporate tax system or the SBC regime, claiming all eligible deductions is essential. Every legitimate expense you claim reduces your taxable income and, in turn, your tax bill.

Common deductible business expenses include:

• Salaries and wages paid to employees
• Rent for business premises
• Utilities such as electricity and water used for business
• Office supplies and consumables
• Professional fees for accountants, lawyers and consultants
• Insurance premiums for business-related policies
• Marketing and advertising costs

For assets used in your business, items costing less than R7,000 each can be written off immediately in the year you buy them. SBC-qualifying businesses also benefit from accelerated depreciation, which allows you to claim a larger portion of an asset's value in the early years rather than spreading it evenly over its useful life.

If you work from home, you may be able to claim a home office deduction. SARS allows this if a specific room or area is used regularly and exclusively for business. The deduction covers a proportionate share of rent or bond interest, rates, electricity, and cleaning costs.

Commonly missed deductions

Many small business owners leave money on the table by overlooking deductions they're entitled to claim. Here are some that are frequently missed:

• Telephone and internet costs used for business purposes
• Training and development expenses for yourself or your staff
• Travel costs, including fuel, tolls, and vehicle maintenance for business trips
• Bad debts that have been written off
• Subscriptions to trade publications or professional bodies

Keep detailed records and receipts for every expense. SARS may request supporting documentation during an audit, and you'll need to prove that each claim is genuine and business-related.

VAT obligations for small businesses

Value-Added Tax (VAT) is a consumption tax charged at 15% on most goods and services in South Africa. Whether you need to register depends on your annual turnover.

VAT registration is compulsory if your business's taxable supplies exceed R2.3 million in any consecutive 12-month period, following the increase from R1 million announced in the 2026 Budget (effective 1 April 2026). You can also register voluntarily if your turnover is below this threshold, which may benefit you if your customers are VAT-registered businesses that can claim input tax.

Once registered, you charge VAT (output tax) on the goods and services you sell, and you can claim back the VAT you've paid on business purchases (input tax). The difference between the 2 is what you pay to, or receive from, SARS.

VAT returns are typically submitted every 2 months via SARS eFiling, though some businesses may qualify for different filing periods. It's important to file and pay on time; SARS imposes penalties and interest on late submissions.

If you're on the Turnover Tax system, and your taxable supplies are below R2.3 million, you don't need to register for VAT compulsorily. You can still register voluntarily if it suits your business, though.

Provisional tax: What small businesses need to know

Provisional tax isn't a separate tax; it's a way of paying your income tax in advance. Instead of settling your full tax bill at the end of the year, you make payments during the year based on your estimated taxable income.

You're a provisional taxpayer if you earn income that isn't subject to employees' tax (PAYE). This includes most business owners, freelancers and self-employed individuals, as well as companies and CCs.

There are 2 compulsory provisional tax payments each year. The 1st payment is due within 6 months after the start of your year of assessment (typically by the end of August for businesses with a February year-end). The 2nd payment is due by the last day of your year of assessment (typically the end of February).

You can also make an optional 3rd payment within 6 months after your year-end to top up any shortfall and avoid interest charges.

Getting your estimate right matters. If you understate your taxable income by more than the permitted margin, SARS can charge penalties on the shortfall. A good approach is to base your estimate on the previous year's actual taxable income and adjust for any known changes in revenue or expenses.

How to register your business with SARS

Before you can pay tax, you need to be registered with SARS. Here's the process step by step.

1. Register your business entity with the Companies and Intellectual Property Commission (CIPC) if you're setting up a Pty Ltd or CC. Sole proprietors don't need CIPC registration but should register a trading name if applicable.
2. Create a SARS eFiling profile at the SARS website. You'll need your identity document, proof of address and your CIPC registration number (if applicable).
3. Register for the relevant tax types through eFiling. At a minimum, you'll need to register for Income Tax. Depending on your circumstances, you may also need to register for VAT, Pay As You Earn (PAYE), the Unemployment Insurance Fund (UIF), and the Skills Development Levy (SDL).
4. Set up your banking details on your SARS profile. This allows SARS to process refunds directly into your account and enables electronic payments.

The entire process can be done online through SARS eFiling, though you may need to visit a SARS branch to verify your identity if this is your first registration.

Key tax deadlines for small businesses

Missing a deadline can result in penalties, interest and even legal action from SARS. Staying on top of these dates is essential for every small business.

Here are the key dates to note:

• Income tax returns: The filing season typically opens in July each year. Companies and CCs must file within 12 months of their financial year-end.
• Provisional tax (1st payment): due within 6 months after the start of your year of assessment.
• Provisional tax (2nd payment): Due by the last day of your year of assessment.
• VAT returns: Due by the 25th of the month following the end of your VAT period (every two months for most businesses).
• PAYE, UIF, and SDL: Monthly returns and payments are due by the 7th of the following month.

SARS charges a fixed penalty for each month your return is outstanding, based on your assessed taxable income. Interest is also charged on late payments. Setting up calendar reminders or using accounting software with built-in deadline alerts can help you stay compliant without the stress.
