How to Survive a SARS VAT Audit (and how Xero helps)

/

Let’s be honest — getting a message from SARS saying you’ve been selected for a VAT verification or audit can make your stomach drop. Even if you know everything has been done correctly, it’s still stressful.

Most VAT audits and reviews are manageable, especially when your records are kept properly and your VAT is prepared using accounting software like Xero.

SARS uses two different processes, and they are not the same thing.

VAT verification

This is a basic “show us your proof” check. SARS wants to confirm that the VAT return matches the documents behind it.
This usually happens after submitting a VAT return or when a refund is claimed.

SARS will:

  • Send a letter via eFiling

  • Ask for specific documents

  • Aim to complete the process fairly quickly once documents are submitted

VAT audit

This is more detailed. SARS looks at how VAT is applied across your business, sometimes over multiple VAT periods. They may request:

  • Accounting records

  • Bank statements

  • Contracts and explanations

This can take longer, but it doesn’t automatically mean something is wrong.

SARS’s powers (and your obligations)

SARS operates under the Tax Administration Act (TAA). In simple terms, this means:

  • SARS is allowed to ask for relevant information to check VAT compliance

  • You must respond within the timeframe given

  • If information is not provided, SARS can raise estimated VAT assessments, plus penalties and interest

That’s why responding properly — and on time — is crucial.

What SARS usually asks for in a VAT audit

Most VAT audits and verifications focus on the same core items.

VAT records

  • VAT201 returns

  • VAT control account

  • Trial balance or general ledger

Invoices and supporting documents

  • Tax invoices for input VAT claimed

  • Sales invoices for output VAT

  • Credit notes and debit notes

If SARS cannot link VAT claims back to valid tax invoices, they are entitled to disallow the VAT — even if the expense itself was legitimate.

Bank statements

  • Full bank statements for the VAT period

  • SARS often checks that income declared matches money received

Business information

  • A short explanation of what your business does

  • Contracts with customers or suppliers

  • Lease agreements or proof of business premises

How Xero helps reduce VAT audit risk

This is where using Xero properly makes a huge difference.

When we prepare your accounting records and VAT using Xero, we’re doing far more than just submitting numbers to SARS.

1. Everything is linked and traceable

Xero allows every VAT amount to be linked back to:

  • An invoice

  • A bill

  • A receipt

  • A bank transaction

This makes it much easier to prove VAT claims during a SARS review.

2. VAT control accounts can be reconciled

One of SARS’s biggest red flags is when:

  • The VAT201 does not reconcile to the accounting records

With Xero, we can:

  • Reconcile VAT control accounts properly

  • Spot errors early

  • Fix problems before SARS ever asks questions

3. Bank feeds improve accuracy

Direct bank feeds mean:

  • Transactions are captured completely

  • Income is less likely to be missed

  • SARS bank-to-turnover checks are easier to explain

Missing or inconsistent bank transactions are a very common audit trigger.

4. Supporting documents are stored securely

When invoices and receipts are attached in Xero:

  • Documents are not lost

  • SARS requests can be answered quickly

  • There’s less panic when deadlines arrive

5. Patterns and anomalies are easier to spot

Xero makes it easier to identify:

  • Unusual VAT refunds

  • Large once‑off expenses

  • VAT percentages that don’t look right

These are exactly the things SARS focuses on.

What clients can do to limit VAT audit risk

Even when we do your VAT, there are a few things clients must still help with.

Things that really help

  • Send us invoices and receipts on time

  • Don’t pay business expenses from personal accounts unless necessary

  • Tell us about unusual or large transactions

  • Flag once‑off deals, deposits, refunds or reversals

Things that cause problems

  • Missing invoices

  • Claiming VAT on non‑business expenses

  • Uploading bank statements late

  • Not telling us when something has changed in the business

Most VAT issues are not “tax fraud” — they are simply missing information.

If SARS contacts you — what to do

If you receive a VAT verification or audit letter:

  • Don’t ignore it

  • Don’t panic

  • Don’t respond without checking with us

Send the letter to us straight away. We’ll:

  • Review exactly what SARS is asking for

  • Prepare the correct documents

  • Make sure everything reconciles properly

  • Respond in a clear, professional way

Responding correctly the first time can prevent weeks (or months) of unnecessary back‑and‑forth.

SARS VAT audits are becoming more common, more detailed, and more data‑driven.
The best defence is good records, good systems, and good communication.

Using Xero properly — and using it consistently — puts you in a far stronger position if SARS ever comes knocking.
