Small business tax refresher course

Tax Tune-Up: A short refresher on all things small business tax

As the tax season swings into action again once again, small business owners in South Africa must equip themselves with up-to-date tax knowledge to ensure compliance, maximise their deductions, and streamline financial processes. Understanding the tax landscape is crucial for the success and growth of any SME. In this comprehensive refresher “course”, we will cover essential tax concepts, obligations, deductions, and practical tips to refresh your small business tax knowledge.

First up, let’s dive a little bit deeper and understand the South African tax system for SMEs.  

What is small business tax?

Small businesses are the backbone of the economy. They produce goods and services, create jobs, and contribute to economic growth. But, in order for them to grow and thrive, they need a business environment that is conducive to their needs. And this means that they need tax policies which are fair, competitive and promote economic growth. Small business tax falls under Corporate Income Tax (CIT), which according to SARS is a tax imposed on companies' resident in the Republic of South Africa i.e. incorporated under the laws of, or which are effectively managed in, the Republic, and which derive income from within or outside the Republic. Non-resident companies which operate through a branch, or which have a permanent establishment within the Republic are subject to tax on all income from a source within the Republic.  

In other words, if you operate a business within South Africa, whether that is a South African business or not, you will need to pay tax on all income. All SMEs that are registered under the ordinary small business tax system will need to pay provisional tax, which means that your tax liability will be spread out over the assessment period (we will explain this a bit further down).

Important small business tax jargon  

Taxpayer Identification Number (TIN)

Before diving into the tax season, ensure that your small business has a valid Taxpayer Identification Number (TIN), also known as the Tax Reference Number (TRN). This unique identifier is crucial for all tax-related activities. A registered company is a separate legal entity with its own TRN, while a sole proprietor business is included in the owner’s personal tax return so it’s TRN is the same as that of the business owner.

Income Tax

The core tax for any business, calculated on the taxable income derived from trade, investment, or other sources.

Value Added Tax (VAT)

Applicable to businesses with an annual turnover exceeding the VAT threshold (currently R1 million). SMEs charge VAT on goods and services supplied and claim input tax credits for eligible purchases.

Pay-As-You-Earn (PAYE)

Relevant if you have employees. PAYE is the withholding tax on employees' salaries, deducted by employers and remitted to SARS (South African Revenue Service).

Skills Development Levy (SDL)

A levy used to fund training initiatives, applicable to employers whose total salaries exceed the prescribed threshold.

Contributions to this fund are mandatory for employers and employees and provide support during periods of unemployment.

What is my small business tax year?  

For sole props, the business tax year is the same as the tax year for individuals. The tax year in South Africa runs from 1st March to 28th/29th February.

Ensure your business is up to date with its tax compliance so that it can conduct business effectively without unnecessary delays. Note, SARS is no longer issuing tax clearance certificates; instead they issue a PIN, which you need to send to the companies that are requesting tax clearance from you. The company will then enter the PIN on SARS eFiling and check if your taxes are compliant.A Tax Clearance Certificate is often required for various business activities, tenders, or government contracts. Ensure your business has a valid certificate to avoid unnecessary delays, and so that you can file your tax return correctly.
