How to Respond to a SARS Request for Reasons: A Complete Guide

A SARS request for reasons is a formal legal procedure where a taxpayer asks the South African Revenue Service to explain the basis of an assessment or a decision. Under the Tax Administration Act (TAA), you are entitled to these reasons if they are not already apparent, allowing you to formulate a clear objection. Effectively managing a SARS request for reasons ensures your small business can challenge unfair assessments with precision and legal backing.

What is a SARS request for reasons?

A SARS request for reasons is a formal application made by a taxpayer under Rule 6 of the Tax Administration Act to understand the justification behind a tax assessment. It is the first critical step when you disagree with a tax bill but do not yet have enough information to file a formal objection. By requesting reasons, you force the Revenue Service to disclose the facts and legal grounds they relied upon to reach their decision.

For South African small business owners, this is a powerful tool. Often, an assessment might be issued after a desk audit or a verification process that feels arbitrary. If the notice of assessment doesn't clearly state why certain expenses were disallowed or why additional income was added, you cannot defend yourself effectively. The request for reasons bridges this information gap. It ensures that the 'audi alteram partem' principle—the right to be heard—is upheld in your dealings with the tax authorities.

Why would a small business need to request reasons from SARS?

You should request reasons when a SARS assessment result is unexpected and the provided assessment notice lacks sufficient detail to allow for a meaningful objection. This commonly occurs when SARS disallows business deductions, VAT input claims, or ignores valid tax credits without a specific explanation. Without these reasons, your subsequent objection may be too vague, leading to it being dismissed or disallowed.

Consider a scenario where your SME claimed R500,000 in qualifying research and development expenses. If SARS issues an additional assessment taxing that amount without explanation, you don't know if they think the expense wasn't incurred, if they believe it wasn't for trade, or if they simply lost your supporting documents. Requesting reasons forces SARS to pinpoint the issue. This allows you to gather the specific proof needed rather than guessing what went wrong.

How do you submit a SARS request for reasons officially?

To submit a SARS request for reasons, you must use the eFiling platform or visit a SARS branch to lodge a 'Notice of Objection' (NOA) form, specifically selecting the option to request reasons first. This must be done within 30 business days of the assessment date to remain within the prescribed legal timeframes. Ensure you clearly identify the specific items or adjustments in the assessment that you are questioning.

Using eFiling for your request

Most small businesses in 2026 use the SARS eFiling portal for all interactions. To initiate the process, log in and navigate to the 'Returns History' section. Find the specific tax type—be it Income Tax (ITR14/ITR12) or VAT—and locate the assessment in question. There will be an option to initiate a dispute. Before you file an objection, the system will allow you to select 'Request for Reasons.' This is the preferred digital route as it creates an immediate digital paper trail and a case number.

Legal timeframes you must follow

In the South African tax calendar, timing is everything. You have 30 business days from the date of the assessment to lodge your request. If you miss this window, you must provide 'senior official' level justification for the delay, which is often difficult to get approved. Once you submit the request, SARS generally has 45 business days to respond, though they can extend this if the matter is complex. Understanding these dates prevents you from losing your right to object later.

What are the legal requirements for a valid request?

A valid request for reasons must be in writing, specify the assessment it refers to, and clearly state the aspects of the assessment that require clarification. It is not enough to simply say you 'disagree' with the tax bill; you must point to specific line items. Under Rule 6 of the Dispute Resolution Rules, the request must be delivered to the specific address or digital channel designated by SARS for disputes.

When writing your request, be clinical and professional. Use language like: 'The taxpayer requests the findings on matters of fact and the reasons for the disallowance of the repairs and maintenance deduction amounting to R120,000 as reflected in the assessment dated 15 January 2026.' This specificity prevents SARS from giving a generic, unhelpful response. It also sets the stage for a stronger legal position if the matter eventually goes to the Tax Board or Tax Court.

What happens after you receive the reasons from SARS?

Once SARS provides the reasons for their assessment, you have 30 business days to either accept the findings or lodge a formal objection if you still disagree. The reasons provided will dictate your strategy; for example, if SARS claims a document was missing, your objection will simply include that document. If they cite a specific section of the Income Tax Act incorrectly, your objection will focus on the legal interpretation of that section.

This stage is where many small businesses benefit from automated record-keeping. If SARS argues that your travel allowance claims were not supported by a logbook, having a digital, cloud-based logbook ready for upload makes the objection process seamless. If the reasons provided by SARS are still inadequate, you have the right to request 'further and better' reasons, although this is a more complex legal maneuver.

Assessing the strength of the SARS argument

Read the response from SARS carefully. Sometimes, they might admit to a processing error, which can be resolved through a Request for Correction (RFC) rather than a full dispute. Other times, they may highlight a genuine oversight in your tax filing. If their reasons are legally sound, it may be cheaper and faster to settle the debt or apply for a payment arrangement rather than fighting a losing battle in court.

How to structure an effective response to SARS

To structure an effective response, start by referencing your case number and the date of their correspondence, then address each reason provided by SARS point-by-point. Attach clear, high-quality PDF evidence for every claim you make, such as invoices, bank statements, or contracts. Keep your tone objective and refer directly to the relevant sections of the Tax Administration Act or the Income Tax Act wherever possible.

The Importance of Evidence

In South African tax law, the burden of proof rests on the taxpayer. If you claim an expense is deductible, you must prove it. When responding to reasons, use a numbered list of attachments. If SARS says, 'We disallowed the rental expense because no lease was provided,' your response should be: 'In response to point 1, please find the signed lease agreement for the period March 2025 to February 2026 attached as Annexure A.'

Common Pitfalls to Avoid

Do not become emotional or argumentative in your response. Avoid vague statements like 'This is unfair' or 'My business cannot afford this.' SARS officials operate based on law and internal manuals, not sympathy. Additionally, never ignore a deadline. If you are struggling to gather information, it is better to submit a partial response and request an extension than to let the 30-day window expire and face a final, binding assessment.
