Responding to a VAT supporting document request

Responding to a SARS VAT supporting document request requires South African SMEs to present verified, complete transactional records matching their VAT201 return.

When the South African Revenue Service (SARS) selects a Value-Added Tax (VAT) declaration for verification or audit, vendors receive an official notification requesting supporting documentation to substantiate declared output tax and input tax deductions 1 2.

To maintain compliance and avoid unexpected processing delays or estimated assessments, small and medium enterprises (SMEs) must identify the requested scope period, verify that every invoice and reconciliation schedule strictly matches the submitted VAT201 return, and secure an official submission receipt upon uploading their evidence pack 1 3 4.

Request scope period and submission receipt

Identifying the Audit Purpose and Issuing Authority

When SARS issues a document request, it is essential to determine whether the request stems from a routine verification or a comprehensive audit 2 5. A verification is a targeted, less intensive evaluation focused on checking specific line items—usually on the vendor's most recently submitted return—to ensure accuracy 2 5. In contrast, an audit involves an in-depth examination of multiple tax periods, accounting ledgers, and third-party data to verify overall compliance 5.

— Practical point from this guide

Official requests are transmitted electronically via eFiling under the "SARS Correspondence" section 1. Opening the notification letter automatically activates a dedicated upload link within the "SUPPORTING DOCUMENTS" container on the relevant VAT201 work page 1.

Understanding the Verification Scope and Timelines

The notification letter specifies the precise tax period under review (the scope period) and outlines the specific records required 1 2. Vendors must adhere strictly to the submission timeframe stipulated in the letter 6 7. Under Section 95(1)(c) of the Tax Administration Act, if a vendor fails to furnish the requested material within the prescribed time, SARS is empowered to issue an estimated assessment 8 9.

If additional time is needed to gather records, vendors can submit a formal request for an extension via eFiling prior to the deadline 6 9. Once the evidence pack is uploaded, clicking "Submit to SARS" generates a verified submission receipt and updates the work page status to "Submitted", providing proof of compliance 3.

Documents grouped by purpose: request scope period

Mandatory Tax Documents

To support a VAT201 declaration, SMEs must assemble mandatory source records that provide legal proof for every entry in Part A (Output Tax) and Part B (Input Tax) 4 10. Law and regulator guidance require the following core documents:

• Tax Invoices for Standard-Rated Inputs: Valid tax invoices containing all statutory details (including the supplier’s and recipient’s full registered names, addresses, VAT numbers, serial numbers, and explicit VAT amounts) for standard-rated purchases declared in Fields 14 and 15 10 11 12.
• Import Documentation: Bills of entry (such as Form SAD 500), official SARS Customs receipts for VAT paid, and EDI Customs Status 1 Release Messages for imported goods claimed in Fields 14A and 15A 13 14 15.
• Output Tax Summary Registers: Sales listings, tax invoice registers, and point-of-sale summaries supporting standard-rated supplies, zero-rated supplies, and exempt supplies declared in Fields 1 to 3 4.

Conditional and Transaction-Specific Records

Depending on the nature of the business operations, conditional documentation must be provided:

• Second-Hand Goods Purchases: A fully completed and signed Form VAT264 declaration, proof of payment, and a copy of the non-vendor seller’s identity document or business letterhead to substantiate notional input tax claims 13 16.
• Agency Transactions: Formal statements provided by agents under section 54(3)(b) detailing tax paid and goods acquired on behalf of the principal vendor 10 14 17.
• Third-Party Banking Nominations: Form VAT119i indemnity forms accompanied by corporate resolutions where a vendor is legally permitted to nominate a group subsidiary or holding company bank account 18 19 20.

Recommended Supporting Schedules and Reconciliation Sheets

Evolv recommends preparing internal reconciliation schedules to streamline the reviewer's audit process:

• VAT201 Line-Item Reconciliations: A structured spreadsheet linking every general ledger tax account directly to Fields 1 through 18 of the VAT201 return 4 21.
• Bank Statement Cross-Referencing: Highlighted bank statements matching payment amounts to high-value tax invoices and import receipts 16 22.

Registration Threshold Alignment

When reviewing financial eligibility, SARS applies administrative registration thresholds 23 24 25. Under statutory rules, compulsory registration applies when taxable turnover exceeds R1 million in a 12-month period 23 26, while voluntary registration requires a minimum of R50 000 in historical or expected turnover 24 25. Current SARS administrative guidelines administer an updated compulsory threshold of R2.3 million 25.

This position represents regulator guidance rather than an unqualified statutory amendment to Section 23 of the VAT Act.

Check identity period and consistency: submission receipt

Cross-Checking Entity Details and Tax Numbers

Before submitting an evidence pack, SMEs must conduct a internal consistency check 22. The registered legal entity name, trading name, and 10-digit VAT registration number appearing on tax invoices must match the SARS Notice of Registration exactly 12 27. Invoices issued in the name of individual directors or unlinked third parties will result in disallowed input tax deductions 10.

Validating Tax Periods and Entitlement Windows

Document dates must align directly with the specific tax period under review 4 17. For input tax claims, the supply must have occurred within the verified tax period or within the allowable 5-year statutory window from the date first entitled to the deduction 17 28. Input tax claims older than five years are statutorily barred and will be disallowed upon audit 17 29.

Mathematical Accuracy and Payment Reference Numbers

Output tax and input tax figures must be mathematically verified using the standard tax fraction (15/115 for the 15% VAT rate) 30 31 32. Furthermore, every document bundle must be referenced against the pre-populated 19-digit Payment Reference Number (PRN) generated on eFiling for that specific VAT201 declaration to maintain complete audit trail integrity 33 34.

File Indexing and Naming Conventions

To facilitate rapid processing by SARS auditors, evidence packs should be compiled systematically 1. Evolv recommends creating an electronic file index that mirrors the structure of the VAT201 return:

1. Index Schedule: A master PDF listing every document, invoice number, supplier name, net amount, and VAT amount linked to its specific VAT201 field 4 21.
2. Clear Naming Conventions: Files should be labelled logically using standardized titles, such as Field15_InputTax_Invoices_CategoryA.pdf or Field01_OutputTax_SalesRegister.pdf.
3. Document Formatting: Combine individual invoices into logical PDF bundles, ensuring scans are clear, upright, and legible 1 7.

Submission Channels and Formatting Requirements

Documents must be submitted through authorised digital channels—primarily eFiling or the SARS Online Query System 1 7 35. SARS explicitly rejects photocopied, faxed, or emailed documentation, as well as printed copies of eFiling returns submitted manually at branch offices 36 37 38.

Numbered Checklist for Evidence Pack Assembly

1. Open SARS Correspondence: Extract the official document request letter and record the submission deadline 1.
2. Export VAT201 Calculation Sheets: Retrieve the general ledger summary supporting the specific return version filed 4 39.
3. Gather Primary Invoices: Collect valid tax invoices for standard-rated inputs and cross-check supplier VAT numbers 10 12.
4. Compile Import & Special Files: Attach SAD 500 customs releases, EDI messages, or signed VAT264 forms where applicable 13 15 16.
5. Construct Master Index: Build a reconciliation spreadsheet cross-referencing document totals to VAT201 Fields 1–18 4 21.
6. Upload and Confirm: Upload files into the eFiling "SUPPORTING DOCUMENTS" container, press "Submit to SARS", and archive the "Submitted" receipt 3.

Missing or contradictory records: submission receipt

Authentic Record Reconstruction and Supplier Engagement

If an SME discovers that a primary supplier tax invoice is missing during a verification audit, it must not attempt to create replacement or fictitious documentation 22. Instead, the enterprise should contact the supplier immediately to request an authentic copy clearly stamped or marked "Copy" by the issuer 10.

Statutory Rulings and Prior-Period Omissions

Where an original tax invoice cannot be obtained due to circumstances beyond the vendor's control, Section 16(2)(g) allows a vendor to apply to the Commissioner for a formal VAT ruling authorising alternative documentary proof 40 41. This application must be submitted at least two months prior to the expiry of the 5-year entitlement period, proving that all reasonable steps were taken to obtain the invoice 40 41.

If an input tax deduction was omitted from a past tax period, vendors are legally prohibited from increasing input tax on a revised past VAT201 return 28 42. Regulator guidance dictates that omitted input tax must be claimed in the current or a subsequent VAT return within five years of the original entitlement date 28 42.

• [Omitted Input Tax Identified] > CANNOT alter past VAT201 return 28
• Claim on NEXT VAT201 return (within 5 years) 28 42

Handling Estimated Assessments and Voluntary Disclosures

Where missing records lead to a Section 95(1)(c) estimated assessment, vendors retain the right to submit the outstanding relevant material or request a suspension of payment while submitting the required evidence 6 9. If incomplete or unrecorded tax liabilities are identified across historical periods, businesses can use the Voluntary Disclosure Programme (VDP) to disclose tax defaults voluntarily, obtaining penalty relief provided strict application criteria are met prior to the commencement of an official audit 43 44.

Next steps for VAT refunds

Understanding the 21-Business-Day Statutory Timeline

When a VAT201 return results in a net refund position (Field 20), SARS is legally required to pay the refund within 21 business days of receiving the correctly completed return or all requested supporting documents 45 46 47. If payment is delayed beyond 21 business days without valid statutory cause, SARS is obligated to pay statutory interest at the prescribed rate 46 48.

Grounds for Refund Holds and Interest Suspension

SARS maintains the statutory authority to withhold a refund or suspend the 21-business-day interest clock under specific circumstances 46 49 50:

• Verification or Audit Pending: The refund claim has been selected for verification, inspection, or audit 46 51.
• Outstanding Tax Returns: The vendor has unsubmitted VAT or other tax returns outstanding 46 49 51.
• Defective Banking Particulars: Banking details are unverified, missing, or incorrect 46 49 50.
• Denied Record Access: SARS officers are unable to gain access to the vendor’s books and records 49.

Statutory Record Retention Obligations

Uploading supporting documents to eFiling generates an administrative status of "Submitted", but this does not constitute final assessment or formal legal acceptance by SARS 2 3 51. Vendors must retain all physical and electronic books of account, tax invoices, bank statements, customs documents, and submission receipts for a mandatory minimum period of five years from the date of return submission 52 53 54.

Background and Return Declaration

Apex Manufacturing (Pty) Ltd is a registered VAT vendor operating under Category A (two-month filing period ending May). For the tax period concerned, Apex submitted its VAT201 return via eFiling, declaring the following totals:

• Standard-Rated Supplies (Field 1): R1 150 000 (Exclusive: R1 000 000; Output Tax at 15% in Field 4: R150 000) 30 32.
• Capital Goods Acquired (Field 14): R230 000 (Exclusive: R200 000; Input Tax at 15%: R30 000) 21 55.
• Other Goods/Services Acquired (Field 15): R1 035 000 (Exclusive: R900 000; Input Tax at 15%: R135 000) 21 55.
• Total Input Tax (Field 19): R165 000 21.
• Net Refund Claimed (Field 20): R15 000 (Total Output Tax R150 000 minus Total Input Tax R165 000) 21 33.

SARS Verification Trigger and Response

Upon submission, eFiling generated a pre-populated Payment Reference Number (PRN) and issued an automated document request letter under "SARS Correspondence", selecting the return for verification 1 33. The letter requested supporting evidence for Fields 14 and 15 within 21 business days 1 7.

Apex Manufacturing executed the following steps:

1. Compiled Document Bundle: Assembled 12 primary tax invoices supporting Field 15 (R135 000 input tax) and 1 machinery purchase invoice supporting Field 14 (R30 000 input tax) 10 55.
2. Reconciled Schedules: Built a master PDF index linking each invoice supplier, VAT number, and tax amount directly to Field 14 and 15 return totals 4 21.
3. Uploaded to eFiling: Accessing the VAT201 work page, Apex uploaded Field14_Capital_Machinery.pdf (1 file) and Field15_General_Invoices.pdf (12 files) into the "SUPPORTING DOCUMENTS" container 1 3.
4. Submission Receipt: Clicked "Submit to SARS", generating a confirmation status of "Submitted" on the work page 3.

Outcome

Because all submitted tax invoices were valid and reconciled perfectly to Field 20, SARS finalised the verification within 14 business days, releasing the R15 000 refund directly into Apex’s verified bank account within the statutory 21-business-day window without interest suspension 45 46 47.
