TGC Talks: The Risks of Late or Incorrect VAT Submissions

Introduction: VAT Compliance Is Not Optional — and SARS Takes It Seriously

Value-Added Tax (VAT) is one of the most tightly monitored tax types in South Africa. Unlike income tax, which is filed annually, VAT is submitted regularly throughout the year. This means businesses have more frequent interaction with SARS — and more opportunities to make mistakes.

Late or incorrect VAT submissions are among the most common compliance issues faced by small and medium-sized enterprises. Many business owners underestimate the seriousness of these mistakes until they are faced with penalties, interest charges, or even a SARS audit.

Understanding how VAT submission cycles work, what happens when deadlines are missed, and how to correct errors is essential for protecting your business from unnecessary financial and legal risk.

Understanding VAT Submission Cycles in South Africa

Once your business is registered for VAT, you are required to submit VAT returns according to the category assigned by SARS. These categories determine how often you must submit returns and pay VAT.

The most common VAT categories are:

Category A

· VAT periods end on the last day of every second month, typically covering January–February, March–April, and so on.

Category B

· VAT periods also cover two months but are offset, usually February–March, April–May, etc.

Category C

· Monthly submissions, generally assigned to businesses with high turnover or specific risk profiles.

Each VAT period has a strict submission and payment deadline. Returns are usually due by the 25th of the month following the end of the VAT period, or the last business day of that month if submitted via eFiling.

Missing these deadlines — even by a single day — can trigger automatic penalties.

Penalties for Late VAT Submissions

One of the most important things for business owners to understand is that SARS penalties for late VAT submissions are not discretionary — they are applied automatically.

Typical consequences of late submission include:

· Administrative penalties for missing the deadline

· Interest charged daily on any outstanding VAT amount

· Accumulating compliance risk, which may affect your overall SARS profile

Even if your business has no VAT payable for that period, failing to submit a return can still result in penalties because the obligation is to submit the return, not just to make a payment.

Over time, repeated late submissions can lead to increased scrutiny from SARS and a higher likelihood of audit selection.

The Risks of Submitting Incorrect VAT Returns

While late submissions are risky, incorrect submissions can be even more serious. Errors in VAT returns may lead to underpayment or overpayment, both of which can create complications.

Common VAT errors include:

· Incorrect VAT calculations on sales or purchases

· Claiming input VAT on non-qualifying expenses

· Failing to account for zero-rated or exempt supplies correctly

· Duplicate or missing invoices

Under-declaring VAT — whether intentional or accidental — is viewed as a compliance risk by SARS and may result in additional penalties beyond standard interest.

Over-declaring VAT can also harm your business by reducing your available cash flow and complicating future reconciliations.

How VAT Errors Can Trigger SARS Audits

SARS uses sophisticated risk assessment systems to monitor taxpayer behaviour. Patterns such as frequent corrections, large input VAT claims, or inconsistent reporting may flag a business for review.

Situations that often trigger audits include:

· Repeated late submissions

· Sudden drops or spikes in VAT payable

· Input VAT claims that are unusually high relative to turnover

· Discrepancies between VAT returns and income tax or financial statements

Once a business is selected for audit, SARS may request:

· Supporting documentation

· Bank statements

· Supplier invoices

· Detailed explanations of specific transactions

Preparing for and responding to a SARS audit can be time-consuming and stressful, particularly if your financial records are not well organised.

Real-World Scenarios Where Businesses Get Into Trouble

Many VAT compliance issues do not arise from deliberate wrongdoing, but from everyday business pressures and administrative oversight.

Example 1: The Busy Business Owner

A business owner focusing on operations forgets to submit a VAT return on time. By the time the oversight is noticed, penalties and interest have already accumulated.

Example 2: Incorrect Input VAT Claims

A company claims VAT on expenses that are partially for private use, such as mixed-use vehicles or home office costs. During a review, SARS disallows these claims and demands repayment with penalties.

Example 3: Cash Flow Constraints

A business submits VAT returns on time but delays payment due to cash flow problems. Interest accrues daily, and SARS may initiate collection processes if the debt remains unpaid.

These scenarios highlight how easily VAT issues can escalate when there is no structured system in place to manage compliance.

How to Correct VAT Errors with SARS

Mistakes in VAT submissions are not uncommon, and SARS provides mechanisms for correcting them. However, corrections must be handled carefully to avoid further complications.

The correction process typically involves:

· Identifying the error through reconciliation

· Submitting a revised VAT return or correction on eFiling

· Providing supporting documentation if requested

If errors relate to multiple periods or involve significant amounts, businesses may need to submit a Voluntary Disclosure Programme (VDP) application to regularise their tax affairs and reduce penalties.

Attempting to ignore or conceal VAT errors is likely to worsen the situation, as SARS systems and audits often uncover discrepancies over time.
