SARS VAT Audit Preparation Checklist for South African Vendors

A SARS VAT verification or audit is usually won or lost on the audit trail. The VAT201 figures must reconcile to sales reports, supplier invoices, import documents, bank records, accounting ledgers, and the specific supporting documents SARS requested. A clean VAT file makes the response faster and reduces the risk of an estimated assessment, disallowed input VAT, penalties, and delayed refunds.

Use this checklist before submitting a VAT201 return that may produce a refund, before uploading relevant material, or after receiving a SARS verification letter.

Key Takeaways

A VAT vendor must submit a VAT201 return for every tax period and keep records that prove output tax and input tax.

SARS can ask for relevant material through eFiling when a return is selected for verification or audit.

Input VAT normally depends on valid tax invoices or approved alternative documents.

VAT records should create a clear trail from the VAT201 return to invoices, bank records, ledgers, and customs documents.

If SARS issues a section 95 estimated assessment because supporting documents were not provided, eFiling may allow relevant material or an extension request within specific time limits.

First read the SARS letter

Do not upload a general bundle before reading the SARS request. The letter tells you the tax period, the case type, the due date, the documents requested, and the channel for submission. Build your response around that request.

Create a working folder with:

SARS verification or audit letter.
VAT201 return and VAT217 assessment notice, if issued.
VAT control account for the period.
Output tax schedule.
Input tax schedule.
Sales and purchases reconciliations.
Bank statement extracts.
Supporting invoices and credit notes.
Import or export documents where relevant.
A short index explaining what each file proves.

If the return is under audit because of a refund, prepare the refund explanation first. SARS needs to see why input tax exceeds output tax: export sales, major capital purchases, seasonal purchases, once-off stock build-up, or corrections.

Reconcile the VAT201 before uploading

The VAT201 should not be a standalone number. Reconcile each field back to the accounting records.

VAT201 area	Reconcile to	Common problem
Standard-rated sales	Sales ledger, invoices, point-of-sale reports, bank receipts	VAT-inclusive totals entered as VAT-exclusive figures
Zero-rated sales	Export file, zero-rated schedule, contracts, proof of export	Zero-rating claimed without the required proof
Exempt supplies	Separate exempt schedule	Exempt sales treated as zero-rated sales
Output tax adjustments	Credit notes, debit notes, bad-debt records	Adjustments claimed in the wrong period
Input tax	Supplier invoices, purchase ledger, import VAT documents	Missing or invalid tax invoices
Capital goods	Asset invoices, payment proof, asset register	Private or mixed-use assets claimed in full
Diesel, if applicable	Diesel logbooks and supporting schedules	Diesel amounts not matching qualifying activity

SARS officials do not calculate the VAT201 figures for the vendor. The vendor or representative is responsible for the calculation, submission, and supporting explanation.

Output tax checklist

For sales and output tax, prepare:

VAT201 return for the period.
Sales invoice listing showing invoice number, date, customer, VAT rate, VAT-exclusive value, VAT amount, and VAT-inclusive total.
Credit note and debit note schedules.
Point-of-sale summaries, if the business uses a till or retail platform.
Bank reconciliation showing sales deposits or merchant settlements.
Treatment notes for standard-rated, zero-rated, exempt, and out-of-scope items.
Contracts or delivery records for unusual transactions.

Check that advertised and invoiced prices include VAT where required. A VAT vendor must collect VAT on taxable supplies and include VAT in prices advertised or quoted, unless a lawful exception applies.

Input tax checklist

For purchases and input tax, prepare:

Supplier tax invoices.
Purchase ledger and input VAT schedule.
Proof of payment where SARS asks for it or where second-hand goods or unusual claims are involved.
Import VAT bills of entry and customs documentation.
Asset invoices for capital purchases.
Apportionment calculation where the business makes taxable and exempt supplies.
Entertainment, passenger motor vehicle, private-use, and blocked-input review.
Credit notes received from suppliers.

SARS states that the tax invoice is the most important document in the VAT system. Without a proper tax invoice, a vendor generally cannot deduct input tax on business expenses.

A full tax invoice is required where the consideration is more than R5,000. An abridged tax invoice may be used where the consideration is R5,000 or less, and a tax invoice is not required where the consideration is R50 or less, although a till slip or sales docket showing VAT may still be needed to verify the input tax deducted.

Valid tax invoice controls

Check supplier invoices before claiming input VAT. The invoice should show:

The words “Tax Invoice”, “VAT Invoice”, or “Invoice”.
Supplier name, address, and VAT registration number.
Recipient name, address, and VAT registration number where the recipient is a vendor.
Serial number and date of issue.
Accurate description of goods or services.
Quantity or volume supplied.
Value of the supply, VAT charged, and total consideration.

If a supplier invoice is missing a VAT number, has the wrong recipient, or is only a quotation or pro forma invoice, do not assume it supports an input claim. Get a corrected invoice before SARS asks for it.

Export and zero-rated supply proof

Zero-rated supplies are high audit-risk because the VAT rate is 0% but input VAT can still be claimed. For export sales, keep a complete export pack:

Customer order or contract.
Commercial invoice.
Packing list, if applicable.
Customs export declaration.
Transport documents.
Proof that goods left South Africa.
Proof of payment.
Clearing-agent correspondence.
Foreign-currency conversion working paper.

If the business exports regularly, keep separate folders for direct exports, indirect exports, and local zero-rated supplies. The proof requirements can differ.

Upload workflow for eFiling

When uploading relevant material:

Name files clearly, for example 2026-04 VAT201 sales reconciliation.pdf.
Use an index if there are many files.
Keep each file readable and complete.
Upload only documents relevant to the SARS request.
Save the upload confirmation.
Record the case number, submission date, and person responsible.
Monitor eFiling correspondence until SARS finalises the case.

If SARS issues an estimated assessment because supporting documents were not submitted, the VAT201 guide explains that eFiling can show options to submit relevant material, request an extension, or request suspension of payment, depending on the case status and timing.

Common VAT audit findings

VAT201 totals do not reconcile to the accounting system.
Input VAT is claimed from non-vendors or without valid tax invoices.
VAT-inclusive amounts are treated as VAT-exclusive.
Export sales are zero-rated without sufficient proof.
Exempt supplies are treated as zero-rated supplies.
Entertainment or passenger motor vehicle input VAT is claimed incorrectly.
Private expenses are claimed as business purchases.
Credit notes are included in the wrong period.
Supplier VAT numbers are not checked.
Bank deposits do not match sales reports.

Frequently Asked Questions

What does SARS ask for in a VAT audit?

SARS may ask for VAT201 schedules, output tax records, input tax records, valid tax invoices, credit notes, bank statements, accounting ledgers, import documents, export proof, and explanations for unusual refunds or corrections. The exact list depends on the verification letter.

Can SARS disallow input VAT if I paid the supplier?

Yes. Payment alone is not enough. A vendor generally needs a valid tax invoice or approved supporting document to deduct input VAT. Bank statements support the audit trail, but they do not replace the tax invoice requirement.

How long should VAT records be kept?

SARS says VAT vendors must retain records for five years. For practical audit purposes, keep transaction files, invoices, customs records, ledgers, VAT201 returns, assessments, and SARS correspondence in a format that can be produced quickly.

What should I do if I cannot meet the upload deadline?

Check the SARS letter and eFiling case options immediately. The VAT201 guide explains that, in certain estimated-assessment cases, eFiling may allow a request for extension to submit relevant material. Do not wait until the deadline has passed.
