SARS asked for documents on your VAT application

What happens when SARS asks for more documents on a South African VAT registration application, the five-business-day window, and backdating evidence.

You applied for VAT registration expecting a number by return. Instead, a formal letter from SARS asks for additional supporting documents. It is easy to set aside for a few days while you gather things together, and that is exactly the wrong move, because the window to respond is now very short.

This article explains how VAT registration applications work, what the letter means, how quickly you must respond and what happens if you do not, the evidence SARS asks for when a registration is backdated, and how to build the pack from your own books so it is ready in time.

How the application normally goes

SARS says a VAT registration application must be made through eFiling, or through a virtual appointment, by telephone or video, booked through its eBooking system. Where no risk is identified, SARS issues a VAT number immediately.

So a request for documents is SARS's signal that it wants more before it registers you. It is not a refusal. But it does put the application on a clock.

Five business days from the date of the letter

SARS says that from 8 December 2025, where it asks for additional or outstanding supporting documents for a VAT registration application by formal letter, the applicant has five business days from the date of the letter to upload them. If they are not uploaded in that time, the system automatically rejects the application.

Two details in that rule catch people out:

• The window runs from the date of the letter, not from the day you open it. If the letter sat unread in an inbox for two days, you have three left.
• Rejection is automatic. Nobody at SARS decides to give you a little longer. When the window closes, the application is rejected and you start again.

So treat the letter as urgent the day it arrives. Read it, list exactly what it asks for, and upload everything you have within the window rather than waiting to perfect the pack.

SARS announced the change in a news item on its VAT page, which also links to registration, returns, refunds and the VAT guides.

Evidence when a registration is backdated

Backdating is one situation where SARS's own pages say supporting documents are needed: the evidence has to justify the date the registration is meant to start.

Compulsory registration. SARS says eFiling (the RAV01) only allows a compulsory VAT registration to be backdated up to 6 months from the date the R2.3 million threshold was exceeded. Backdating further than that requires a branch appointment with supporting documents, such as financial statements, contracts or invoices.

Voluntary registration. SARS says a voluntary registration takes its liability date from the date of application, and cannot be backdated unless the applicant provides supporting documents to justify the backdating.

In both cases the question SARS is asking is the same: what evidence shows that the business's taxable supplies justify the date you are asking for? The documents it mentions answer that.

How the compulsory threshold works is covered in when a South African business must register for VAT, and the voluntary route in registering for VAT voluntarily in South Africa.

Building the evidence from your own books

With only five business days, the evidence has to come from somewhere quick. If your books are already in Achekam, most of it is a matter of running reports.

Turnover by period. Management accounts show an income statement for a chosen period beside the period before, and a balance sheet at period end, both added up from your own journals and exportable as PDF or CSV. Run them month by month across the period in question to show when turnover crossed the threshold. Note that the year-to-date preset starts on 1 January, not on your own year start, so pick the dates yourself when you need a particular 12-month window.

Money received. A business imports bank statements as PDF, CSV, Excel, OFX, QIF, MT940 or CAMT.053, and each import is checked so that the opening balance plus movements equals the closing balance. Statements already imported for the period give SARS the receipts behind the turnover. Where a workspace has an AI model configured, it can read scanned or unrecognised PDF statements, and every amount it reads must appear on the page.

Management accounts are not audited financial statements, so if SARS asks specifically for financial statements, ask your accountant whether they can be prepared in time or whether management accounts will do for this request.

Keeping the application pack in one folder

Gathering the pack is half the job; keeping it together is the other half. Achekam's Document Centre is a folder-based store where a business uploads files or whole folders, previews, downloads, renames, moves, tags, archives and searches them, and a new version keeps the earlier ones.

Create one folder for the VAT application and keep everything in it: SARS's letter, the management accounts you ran, the bank statements, the contracts and a sample of invoices. Uploads go in batches of up to 25 files, at 100 MB per file by default. If SARS asks a follow-up question, or the application has to be made again, the pack is ready.

The day the letter arrives

Note the date on the letter, count five business days, and put the deadline in front of whoever is handling it. List the documents requested, pull the reports from your books the same day, and upload what you have before the window closes. A complete pack uploaded on day three is worth far more than a perfect one finished on day six.
