Self-Employed Tax in South Africa

How is a sole proprietor taxed in South Africa?

A sole proprietor in South Africa is not a separate legal entity for tax purposes. Business profit and personal income merge into a single taxable amount reported on the ITR12 individual return filed with the South African Revenue Service (SARS) via eFiling. The same progressive brackets that apply to salary earners apply to business profit, minus allowable expenses incurred in the production of that income under Section 11(a) of the Income Tax Act 58 of 1962.

Because the sole proprietor receives no employer who withholds Pay-As-You-Earn (PAYE), the law classifies them as a provisional taxpayer under the Fourth Schedule to the Income Tax Act. This means the taxpayer must estimate their own annual tax liability and pay it in instalments before the final annual return reconciles the actual position. The ITR12 filing window for the 2025/26 year (ending 28 February 2026) opens in July 2026 and closes at the end of January 2027 for provisional taxpayers using a registered tax practitioner.

What are the 2025/26 income tax rates for individuals?

For the tax year 1 March 2025 to 28 February 2026, SARS applies the following progressive marginal rates to taxable income earned by resident individuals, including sole proprietors [C1]:

Three annual rebates reduce the gross tax liability. The primary rebate of ZAR 17,235 applies to every resident individual under 65 and effectively produces a tax-free threshold of ZAR 95,750 for the 2025/26 year. A secondary rebate of ZAR 9,444 applies to taxpayers aged 65 to 74, raising the effective threshold to ZAR 148,217. A tertiary rebate of ZAR 3,145 applies from age 75, producing a ZAR 165,689 threshold [C1].

For example, a sole proprietor with ZAR 500,000 of net business profit after expenses pays approximately ZAR 90,000 in income tax (effective rate roughly 18%), compared with roughly ZAR 350,000 at the 45% top marginal rate if profit exceeds ZAR 1.88 million.

How does provisional tax work for self-employed individuals?

Self-employed individuals are required to make two compulsory provisional payments each year using the IRP6 return on SARS eFiling [C2]:

• First payment: Due by 31 August 2025 for the 2025/26 year. Based on 50 percent of the estimated annual tax liability for the full year.
• Second payment: Due by 28 February 2026 (the last day of the tax year). A revised estimate covering the full year's income, topped up to the total estimated liability after deducting the first payment.
• Optional third payment: Due by 30 September 2026 after year-end. Voluntary top-up to reduce or eliminate the Section 89quat interest charge on any remaining underpayment before the ITR12 is finalised.

If the second payment estimate falls short of 90 percent of the actual assessed taxable income (or below the prior-year "basic amount" for those earning under ZAR 1 million), SARS may levy a 20 percent underestimation penalty on the shortfall. Late payment of any instalment attracts a further 10 percent penalty. Both instalments are submitted electronically through the IRP6 form on SARS eFiling [C2].

What is the Small Business Corporation alternative?

A sole proprietor who incorporates into a private company may qualify for the Small Business Corporation (SBC) reduced tax rates under Section 12E of the Income Tax Act [C3]. The SBC is a company vehicle, not available to unincorporated sole traders, but it is a legitimate structural option.

For the 2025/26 year of assessment (companies with year-ends 1 April 2025 to 31 March 2026), SBC rates are:

• 0% on taxable income up to ZAR 95,750
• 7% on income from ZAR 95,751 to ZAR 365,000
• 21% on income from ZAR 365,001 to ZAR 550,000 (plus ZAR 18,848 on the lower band)
• 27% on income above ZAR 550,000 (plus ZAR 57,698 on lower bands)

Key qualifying conditions include: all shareholders must be natural persons; at least one shareholder or director must be full-time in the business; the entity must not be a personal service provider; and gross income must not exceed ZAR 20 million per year. The SBC trades tax compliance complexity (company-level returns, annual audits or independent reviews in some cases) for a considerably lower effective rate on moderate profits. A qualified tax professional can model whether incorporation makes financial sense for a specific business before any structural change is made.

What is the Turnover Tax regime for micro-businesses?

Turnover Tax is a simplified tax system designed to reduce compliance costs for very small businesses with qualifying annual turnover under ZAR 2.3 million (increased from ZAR 1 million, effective 1 April 2026) [C4]. It replaces income tax, VAT, provisional tax, capital gains tax, and dividends tax in a single annual payment based on gross receipts rather than profit.

The rates for the year commencing 1 March 2026 are:

• 0% on turnover up to ZAR 600,000
• 1% on turnover from ZAR 600,001 to ZAR 950,000
• 2% on turnover from ZAR 950,001 to ZAR 1,400,000 (plus ZAR 3,500)
• 3% on turnover from ZAR 1,400,001 to ZAR 2,300,000 (plus ZAR 12,500)

Eligible entities include sole proprietors, partnerships, close corporations, companies, and co-operatives meeting the turnover threshold. A business cannot register if it derives income from professional services in certain categories (such as investment income, personal services, or consulting in some forms). The Turnover Tax is registered via SARS eFiling and two interim payments are made by the last business day of August and February respectively, with a final payment after the annual TT03 return. Simplicity is the key advantage; the trade-off is that profitable low-overhead businesses may pay more than under the standard income tax regime with expense deductions.

When must a sole proprietor register for VAT?

VAT registration becomes compulsory when taxable supplies in any rolling 12-month period reach ZAR 1 million under Section 23 of the Value-Added Tax Act 89 of 1991 [C5]. Registration is mandatory within 21 business days of reaching or expecting to reach that threshold. The standard VAT rate is 15 percent (increased from 14 percent on 1 April 2018).

Voluntary registration is available once taxable supplies exceed ZAR 50,000 in the preceding 12 months, providing access to input-tax credits on business purchases even before compulsory registration kicks in. Practical note: from 1 April 2026, budget legislation raised the compulsory threshold to ZAR 2.3 million and the voluntary threshold to ZAR 120,000 for entities registering under the new rules. Businesses already registered under the prior ZAR 1 million threshold remain registered; the higher threshold affects new registrations and de-registration eligibility [C5].

Once registered, VAT201 returns are submitted bi-monthly by default, with payment due on the 25th of the month following the period. Zero-rated supplies include most basic foodstuffs (brown bread, maize, rice, vegetables, fruit, milk), exports, and certain services to non-residents. Financial services, residential rent, and educational services are typically exempt.

What expenses can a sole proprietor deduct?

A sole proprietor deducts expenses incurred in the production of business income under Section 11(a) of the Income Tax Act, subject to the general prohibition in Section 23 against private and capital expenditure. Common allowable categories include:

• Direct business costs: stock purchased for resale, raw materials, subcontractor fees, professional fees directly related to the business
• Occupancy costs: rent for business premises, utilities, insurance, maintenance
• Wear and tear (depreciation): SARS publishes write-off periods for different asset classes; computers and electronic equipment are typically written off over 3 years, office furniture over 6 years, vehicles (subject to the Section 11(e) cost ceiling) over 4 to 7 years depending on classification
• Travel and motor vehicle expenses: actual business kilometres at the SARS rate per kilometre, or actual costs apportioned by a vehicle logbook; a company car alternative uses the fringe-benefit tables
• Insurance and professional indemnity: premiums for business-purpose cover are deductible
• Retirement Annuity Fund contributions: up to 27.5% of the higher of taxable income or remuneration, capped at ZAR 350,000 per year under Section 11F
• Business telecommunications, software subscriptions, stationery: fully deductible where used for business

Personal expenses, capital expenditure (subject to depreciation write-down), and fines or penalties are explicitly non-deductible. Where expenditure has a mixed personal and business character, only the business proportion is allowable. A logbook or similar contemporaneous record is required to support proportioned claims under SARS audit.

Home office deduction: A sole proprietor may deduct a portion of household occupancy costs (rates, rent, utilities, cleaning) where a room is used regularly and exclusively for business purposes and is specifically equipped for that use under Section 23(b) of the Income Tax Act [C6]. The formula is: (home office floor area in square metres) divided by (total residence floor area) multiplied by total qualifying premises costs. Equipment, fixtures, and wear-and-tear on office furniture used exclusively in the home office are deductible in full without apportionment. Mortgage bond interest is no longer deductible for home-office claims following the updated Interpretation Note 28 published 4 March 2022. A dining table used occasionally does not qualify; a dedicated study or workspace does.

For a full picture of how business structure, capital gains, and estate planning interact with the self-employment tax position, see the South Africa country overview. Navigating provisional tax estimates, SBC qualification, or complex deduction apportionment is fact-specific work that warrants input from a registered Chartered Accountant (SA) or registered tax practitioner recognised by SARS.
