How to Understand Your SARS Notice of Assessment ITA34: A Guide

A SARS notice of assessment ITA34 is the official document issued by the South African Revenue Service after you submit your Income Tax Return (ITR12). It summarizes your taxable income, rebates, and deductions, ultimately showing whether you owe SARS money or are due a tax refund. This assessment serves as the final determination of your tax liability for a specific financial year.

For many South African small business owners and sole traders, receiving this document via eFiling can be a source of anxiety. However, understanding the SARS notice of assessment ITA34 is the first step toward masterminding your business finances. Whether you are navigating the 2025/2026 tax season or reviewing past filings, clarity on these figures ensures you remain compliant and avoid unnecessary penalties.

What is a SARS notice of assessment ITA34?

A SARS notice of assessment ITA34 is an automated statement issued to taxpayers after their annual tax return has been processed. It acts as a formal record that details how SARS has calculated your tax liability based on the information you provided in your ITR12. It includes your total income, allowable expenses, tax credits, and the final balance due to or by you.

When you submit your return through the SARS eFiling portal, the ITA34 is usually generated almost instantly, unless your return has been flagged for manual verification or audit. For small business owners, this document is vital because it proves your tax compliance status, which is often required when applying for business loans, vehicle financing, or government tenders. It translates your complex business year into a simplified set of figures that dictate your cash flow for the coming months.

How do you read the 'Selected Risk Criteria' section?

The 'Selected Risk Criteria' summary on your ITA34 indicates whether SARS has flagged your return for further verification or an audit. If this section mentions that you have been selected for verification, it means you must submit supporting documents (like your IRP5s, medical aid certificates, or business expense receipts) to justify the figures on your return.

This is a standard procedure and does not necessarily mean you have done something wrong. SARS frequently uses automated algorithms to identify returns that deviate from historical patterns or include significant business losses. As a SME owner, you should check this section immediately upon receiving your SARS notice of assessment ITA34. If verification is required, your refund—if you have one—will be withheld until the process is completed and the 'Letter of Completion' is issued.

What does the 'Summary of Assessment' calculate?

The Summary of Assessment section provides a high-level overview of your taxable income and the resulting tax calculation before rebates are applied. It lists your gross income (all money earned), exempt income, and allowable deductions (such as retirement annuity contributions or business expenses for sole props).

For the 2026 tax year, SARS calculates your tax based on the sliding scales for individuals and trusts, or at a flat rate if your business is registered as a Small Business Corporation (SBC). The summary will show your 'Taxable Income,' which is the amount SARS actually taxes you on. It is important to cross-reference this with your own bookkeeping records to ensure that all business expenses you claimed have been correctly captured as deductions.

Understanding Taxable Income vs. Gross Income

Taxable income is your total income minus any tax-exempt amounts and allowable deductions. Gross income includes every Rand your business earned before any expenses were taken out. In a SARS notice of assessment ITA34, the taxable income figure is the most important number because it determines which tax bracket you fall into. For the year ending February 2026, ensure you are aware of the current tax thresholds to see if your business qualifies for lower rates reserved for small business corporations.

Why are tax rebates and credits significant?

Tax rebates are fixed amounts that reduce the total tax you owe, while tax credits (like the Medical Scheme Fees Tax Credit) specifically offset your liability bit by bit. Every individual taxpayer in South Africa under 65 is entitled to a primary rebate, which effectively creates a tax-free threshold. On your ITA34, these rebates are subtracted from the initial tax calculated on your taxable income, often bringing your final bill down significantly.

How do I know if I owe SARS money or if I am getting a refund?

To determine your final status, look at the very bottom of your SARS notice of assessment ITA34 for the 'Net Amount' or 'Account Summary.' A minus sign (-) in front of the amount usually indicates a credit, meaning SARS owes you a refund. If there is no minus sign, it typically means you have a debt that must be paid to the South African Revenue Service by the specified due date.

If you see a balance due, it might be because your provisional tax payments throughout the year were insufficient to cover your total liability. Conversely, if you are a sole trader who had PAYE deducted from a side salary, you might find you are due a refund if your business expenses lowered your overall tax liability. Always check the 'Payment Advice' section at the end of the document for the exact date by which any outstanding amounts must be settled to avoid interest and penalties.

What are the common codes on an ITA34?

SARS uses specific source codes to categorize different types of income and deductions. For example, code 3601 represents your main salary, while code 4201 relates to investment income. For small business owners, understanding these codes is essential for diagnosing errors in your assessment.

• **Code 3601:** Income from employment (Salary).

• **Code 3810:** Medical aid contributions paid by an employer.

• **Code 4001:** Total contributions made to a Pension Fund.

• **Code 4006:** Total contributions to a Retirement Annuity (RA).

• **Code 4582:** Remuneration for foreign services.

If you notice a code on your SARS notice of assessment ITA34 that does not align with your business activities, it could result in an incorrect tax calculation. In such cases, you may need to file a Request for Correction (RFC) on eFiling to update the information and receive a revised assessment.

What should a small business owner do if the ITA34 is incorrect?

If you believe your SARS notice of assessment ITA34 contains an error, you should first file a Request for Correction (RFC) on eFiling to fix simple data entry mistakes. If the error is more complex or if SARS has disallowed a deduction you believe is valid, you have the right to lodge a formal 'Notice of Objection' (NOO) within 80 business days of the assessment date.

When objecting, you must provide clear evidence, such as invoices, bank statements, or a detailed asset register, to support your claim. As a South African entrepreneur, keeping pristine digital records is the best defense against assessment errors. Do not ignore an incorrect ITA34; even if you think the difference is small, it can impact your 'Tax Compliance Status' (TCS) and your ability to do business with the state or large corporates.

Understanding the Statement of Account versus the ITA34

While the ITA34 is the notice of assessment for a specific year, the Statement of Account (ITSA) provides a rolling view of your entire history with SARS. The ITSA tracks all payments you have made, all assessments issued, and any interest or penalties accrued over time. It is your ultimate 'balance sheet' with the revenue service.

Often, a taxpayer might see a refund on their SARS notice of assessment ITA34 but not receive it in their bank account. This usually happens because there is an outstanding debt from a previous year or an unfiled return elsewhere in their profile. By requesting a Statement of Account on eFiling, you can see if SARS has offset your current year's refund against older debt.

Why does the ITA34 matter for Provisional Taxpayers?

Provisional taxpayers, which include most small business owners and freelancers, must pay tax in two or three installments during the year. The SARS notice of assessment ITA34 acts as the final 'wash-up' that compares what you already paid via the IRP6 returns against what you actually owed.

If your ITA34 shows a large amount due, it likely means your provisional tax estimates (submitted in August and February) were too low. This can trigger 'underestimation penalties' under the Fourth Schedule of the Income Tax Act. To avoid this in the future, ensure your mid-year bookkeeping is accurate so your provisional payments closely reflect your actual year-to-date profit.

How to ensure your next ITA34 is accurate

The most effective way to ensure a smooth assessment process is to maintain monthly accounting records. Many small businesses in South Africa wait until the end of the tax year to tally their receipts, leading to missing deductions and inaccurate filings. By the time you receive your SARS notice of assessment ITA34, it is often too late to find missing paperwork easily.

Using a dedicated bookkeeping platform simplifies this by categorizing expenses as they happen. When you know exactly what your 'Entertainment' vs. 'Travel' expenses are, you can populate your ITR12 with confidence. This precision reduces the likelihood of SARS flagging your return for verification and ensures that when your ITA34 arrives, the 'Net Amount' is exactly what you expected.

Critical Deadlines for the 2026 Tax Season

For the South African tax year ending 28 February 2026, the filing season typically opens in July 2026. Non-provisional taxpayers (individuals earning a salary) usually have until October or November to file. However, most small business owners are provisional taxpayers and have until January 2027 to submit their final returns.

Always check the official SARS announcements for the exact dates, as these can shift slightly. Missing a deadline results in administrative penalties that start from R250 per month, depending on your taxable income. Your SARS notice of assessment ITA34 will reflect these penalties if they have been applied, adding an unnecessary cost to your business overheads.
