AIT Supporting Documents: How to Build a Traceable Source-of-Funds File
A strong AIT file does more than prove that money exists. It explains where the funds came from, how they moved, what tax treatment applies and why the supporting documents, asset-and-liability position and wider SARS record all tell the same story.
Six layers should connect before the application is submitted.
The strongest application is internally consistent across the transaction, supporting documents, tax treatment and taxpayer profile.
Transfer purpose
State what is being transferred, why the transfer is being made and how the transaction relates to the applicant's wider tax and financial position.
Source category
Identify whether the funds arise from savings, property, investments, a loan, inheritance, trust distribution, earnings or another source because SARS asks for different evidence by source.
Origin trail
Show where the money originated and how it moved into the account or asset position now being used for the transfer.
Tax treatment
Prepare the tax explanation and calculations relevant to the source, such as capital gains implications or income already declared where applicable.
Applicant profile
Reconcile the AIT information to the taxpayer's assets, liabilities, residency position, tax returns and other disclosures so the application does not contradict the wider SARS record.
Current supporting documents
Use the latest source-specific documents required by SARS and check date-sensitive evidence such as bank statements before submission.
The evidence should show a flow of value, not a folder of unrelated documents.
For example, a property-sale file may need to connect the sale and conveyancing evidence to the proceeds, banking trail and tax treatment. The exact documents change by source, but the traceability principle stays the same.
The same logic applies to loans, inheritances, trust distributions and investments: the source, ownership, movement of funds and tax consequences should be capable of being followed from the application back to the underlying records.
Evidence test
Can the source be traced from origin → transaction → account → AIT amount?
If any step relies on an unexplained assumption, the file should be repaired before submission rather than waiting for SARS to expose the gap.
AIT delays often begin where the application story and supporting records disagree.
The bank balance exists but its origin is unexplained
Cash in an account proves availability, not necessarily the historical source or tax treatment of the funds.
The transaction story and tax record differ
The application describes a sale, loan or distribution that is not aligned to returns, financial statements or other information already held by SARS.
Documents prove pieces but not the chain
A sale agreement, bank statement and tax calculation exist, but the file does not connect them into one traceable flow of funds.
Source-specific requirements are missed
The applicant submits a generic pack even though SARS publishes different supporting-document requirements for different sources of funds.
Old bank statements are used
SARS currently specifies recency requirements for bank statements in several AIT source categories, so stale evidence can weaken an otherwise coherent file.
Assets and liabilities do not reconcile
The AIT request is inconsistent with the applicant's wider declared asset, liability, investment or loan position.
Use the evidence article to strengthen the file, then connect the wider tax and accounting position.
AIT Clearance
Prepare the full AIT application, taxpayer profile and supporting evidence.
SARS Compliance
Resolve returns, debt or profile issues that can surface during the AIT process.
Tax Services
Connect the transaction to the wider South African tax-return and disclosure position.
Financial Statements
Support company, trust or investment records with credible financial information where relevant.
What applicants usually ask about AIT supporting documents.
What does SARS mean by source of funds for an AIT application?
SARS requires relevant material showing where the capital or value being transferred came from. The evidence depends on the source selected in the application and may include bank statements, sale documents, loan agreements, trust records, investment statements, tax calculations and other supporting records.
Are bank statements enough for an AIT application?
Often not. A bank statement can show that funds are available, but SARS also asks for documents proving where those funds originated. The source-of-funds chain should therefore connect the current balance to the underlying transaction or asset history.
How recent must AIT bank statements be?
SARS currently specifies, for several AIT source categories, that bank statements must be issued no longer than 14 days before the application date. The exact current requirement should be checked against the source category being used before submission.
Does SARS require assets and liabilities for AIT?
Current SARS guidance requires a statement of assets and liabilities for the previous three tax years for AIT applications by individuals, together with source-specific supporting documents and other information applicable to the taxpayer's circumstances.
Can LBA guarantee SARS will approve an AIT application?
No. LBA can help prepare the taxpayer profile, source-of-funds schedule, tax treatment and supporting evidence so the application is coherent and traceable. SARS decides the application and may request further information or conduct verification or audit work.

AIT documentary requirements change by source and taxpayer circumstances. Check the current SARS source-specific requirements when preparing an actual application.
Build the source-of-funds story before the application turns into a document chase.
LBA can map the transaction, tax treatment, source-of-funds evidence and wider taxpayer profile, then prepare the AIT application file around the actual source and current SARS requirements.
