In brief
Source of funds explains the origin and movement of the money involved in a particular transaction or business relationship. Source of wealth explains how an individual accumulated their overall assets or financial position over time.
The two answers may overlap, but they are not interchangeable. A bank may accept that an account is funded from a recent property sale while still asking how the seller acquired the property or built the wider wealth behind the transaction.
When this matters
- Opening a corporate or personal bank account.
- Funding a new company, holding structure, or investment vehicle.
- Making a large capital contribution, loan, acquisition, or asset transfer.
- Onboarding a shareholder, beneficial owner, nominee, or authorised signatory.
- Responding to enhanced due diligence involving a high-risk country, activity, transaction, or politically exposed person.
Key takeaways
- Source of funds is transaction-specific: salary savings, business income, a dividend, a loan, an asset sale, an inheritance, or investment proceeds.
- Source of wealth is broader: employment history, business ownership, investments, inheritance, property, or another long-term wealth-building path.
- A statement without supporting evidence is rarely enough for a material or higher-risk transaction.
- The documents, dates, amounts, names, and account movements should tell one consistent story.
- A bank or professional may ask further questions even when the funds are lawful; the depth of review is risk-based.
Recommended approach
- Identify the exact amount, transaction, sender, recipient, and intended use.
- Write a short chronological explanation in plain language.
- Match every important part of the explanation to evidence.
- Show the movement of money from its origin to the account or transaction.
- Explain the wider wealth background where the amount or risk profile makes that relevant.
- Reconcile inconsistencies before the file is given to a bank, authority, or service provider.
What you will usually need
Depending on the explanation, evidence may include:
- bank statements showing accumulation and transfer;
- employment contracts, salary records, or tax filings;
- company accounts, dividend vouchers, sale agreements, or ownership records;
- property sale documents and evidence of original acquisition;
- loan agreements and evidence of the lender's capacity;
- probate, inheritance, or gift documentation;
- investment statements and redemption confirmations; and
- a group structure showing the relationship between the parties.
Documents should cover both the legal event and the financial trail. A sale agreement proves a sale, but the receiving bank statement shows that the stated proceeds were actually received.
Common mistakes
- Describing the source only as “savings” without explaining how they arose.
- Providing a bank balance but no evidence of the underlying activity.
- Using a loan from a related party without documenting the lender's own source.
- Submitting figures or dates that conflict with contracts, accounts, or tax records.
- Moving funds through several personal or company accounts without explaining the chain.
- Treating a request for further evidence as a rejection rather than a normal part of enhanced review.
Kapiti perspective
A strong file is not the largest bundle of documents. It is a clear narrative supported by a short, complete evidence chain. Kapiti reviews the explanation, the transaction path, the corporate structure, and the supporting records together before an application or onboarding file is submitted.
No adviser can guarantee that a bank or authority will accept a particular document set. The objective is to remove avoidable gaps and make the legitimate commercial and financial story easy to verify.
