How to Submit a Tax Return for Small Business in South Africa

Filing business tax returns can feel overwhelming for many South African small business owners. However, understanding how to submit a tax return for your small business in South Africa is essential for staying compliant with SARS and avoiding costly penalties. The process may vary depending on your business type — whether you’re a sole proprietor, partnership, or registered company — but the goal remains the same: to legally declare your income and ensure accurate tax payments.

This guide is tailored for SMMEs in South Africa, walking you through why tax compliance matters, practical steps to follow, and common mistakes to avoid. By the end, you’ll feel confident and equipped to submit your tax return correctly and on time.

Why This Matters for South African SMEs

For small businesses in South Africa, tax compliance is more than just a legal requirement — it’s a reflection of good business governance and financial discipline. Submitting accurate and timely tax returns affects your business in the following key ways:

Compliance with SARS regulations: All South African businesses generating income are required by the South African Revenue Service (SARS) to register for tax and submit returns annually.
Avoiding financial penalties: Late or incorrect filings can result in penalties ranging from R250 to R16,000 per month, depending on your company turnover and duration of non-compliance.
Access to funding: Whether applying for government grants or a bank loan, funders often require up-to-date tax clearance certificates — issued only if your returns are current.
Business credibility: Filing taxes responsibly shows potential investors, partners, and customers that your operations are legitimate and trustworthy.
Better financial planning: Tax filing forces you to review income, expenses and cash flow — enabling better decision making and growth strategies.

Too many entrepreneurs delay or avoid filing because they fear the process. But with clear steps and resources, the submission process becomes a manageable business practice — and a growth enabler.

Step-by-Step Guide to Submitting a Tax Return for Your Small Business

Step 1: Register your business with SARS

If you haven’t registered your business with SARS yet, this is your first step. Once your business is operational, you must be registered for income tax. For sole proprietors, this is usually the individual’s tax number. Companies receive a separate company tax number upon registration with the Companies and Intellectual Property Commission (CIPC).

To register a business online, visit the SARS eFiling portal.
If registered through CIPC, SARS automatically generates a tax number and sends it to the CIPC-linked email address.

Step 2: Determine the correct type of tax return

The type of return you submit depends on your business structure:

Sole proprietors: Submit an ITR12 (individual income tax return), declaring both employment and business income.
Companies (Pty Ltds): Submit a ITR14 (company income tax return).
Micro Businesses: Registered for turnover tax, these businesses submit the TT03 tax return via eFiling.

You can check your applicable return type under your SARS profile or consult a registered tax practitioner.

Step 3: Gather financial documentation

Keep well-organised records to make filing simple. The documents you’ll typically need include:

Annual financial statements or management accounts
Business income and expense reports
Bank statements
VAT201 forms if you’re VAT registered
Previous tax returns (if applicable)
Proof of expenses and supplier invoices

Cloud-based accounting tools like Xero or Sage Business Cloud can streamline this process.

Step 4: Submit your return via SARS eFiling

All SARS tax returns can be submitted online via the SARS eFiling system:

Login or register for a free SARS eFiling account
Navigate to “Returns Issued” and select ‘Income Tax Returns’
Open the relevant tax year and complete your return
Declare all income, expenses, and deductions accurately
Submit and receive confirmation of submission

The system pre-populates some data, but double-check figures carefully. Always submit before the SARS deadlines (typically 12 months from company year-end).

Step 5: Request your Tax Compliance Status (TCS) if needed

After submitting your return, you may require a Tax Clearance Certificate (now called TCS PIN) to apply for tenders or funding. Apply via eFiling under “My Compliance Profile.” Ensure all returns and payments are up to date before applying.

Real-World Example: How Tax Submission Helped a Local SME

Before: Nomsa runs a small cleaning services company in Durban operating as a registered Pty Ltd. For years, she didn’t submit her company tax returns, believing it wasn’t necessary since her income was under R1 million annually.

Problem: In 2023, she was shortlisted for a municipal cleaning tender that required a valid Tax Clearance Certificate. Upon trying to apply, she discovered her SARS profile was flagged “non-compliant” due to missing ITR14 submissions for the past two years.

Action: With help from a local business coach, Nomsa used eFiling to backfile her company tax returns, declaring income and expenses. She paid nominal penalties (R250 per month) and successfully restored her compliance.

After: Within weeks, Nomsa obtained her TCS PIN and qualified for the government contract — boosting her business income substantially. Now, she files annually and uses cloud software to track finances.

Common Mistakes and How to Avoid Them

Procrastinating and missing deadlines: Set calendar reminders and plan well in advance of financial year-end.
Mixing personal and business expenses: Open a separate business bank account to track income and deductions accurately.
Failing to record all income: Even informal payments count — declare all revenue sources to avoid audits or penalties.
Submitting incorrect forms: Know whether you should file ITR12 or ITR14 based on structure.
Misreporting VAT: If VAT-registered, make sure your income and expenses are correctly reflected.
