In today’s regulated financial landscape, proving the legitimacy of your funds is essential for compliance, transparency, and trust. Whether you're engaging in traditional banking, investment activities, or digital asset transactions, financial institutions and platforms often require documentation to verify both your source of wealth and source of funds. Understanding the difference between these two concepts—and knowing which documents are acceptable—can streamline your verification process and prevent unnecessary delays.
This guide breaks down everything you need to know about acceptable proof for wealth and fund origins, including document types, best practices, and frequently asked questions.
What Is Source of Wealth vs. Source of Funds?
While often used interchangeably, source of wealth and source of funds serve distinct purposes in financial compliance.
Source of Wealth
This refers to how an individual has accumulated their total net worth over time. It provides a broad overview of long-term financial growth and may include income from employment, business ownership, investments, inheritance, or asset sales.

Source of Funds
This focuses on the origin of specific funds used in a particular transaction. For example, if you deposit $50,000 into a trading account, the platform will want to know whether that money came from a recent salary, sale of property, loan proceeds, or another verifiable source.
Both elements are critical for anti-money laundering (AML) and know-your-customer (KYC) protocols across global financial systems.
Acceptable Documents for Source of Wealth
To verify your overall financial standing, institutions typically accept the following documents based on your primary wealth source:
Employment Income
- Recent payslips (within the last 3 months)
- Latest tax return filings
- Bank statements showing salary deposits (last 3 months)
- Employer verification letter stating position, start date, and compensation
Note: Self-employed individuals must also provide audited financial statements or business tax returns.
Investment Income
- Bank or brokerage statements confirming asset management (within 3 months)
- Cryptocurrency exchange balance verification
Business Ownership
- Official proof of ownership, share register, or equity statement
- Most recent corporate tax returns
- Audited financial statements showing profits, dividends, or bonuses
Sale of Assets (Real Estate, Businesses, Equity)
- Copy of the sales agreement indicating amount and receipt of proceeds
- Latest audited financial statements
Inheritance or Gift
- Grant of probate or will certification
- Donor’s letter explaining the reason, amount, and their own source of wealth
- Bank statement showing deposit from donor
- Court orders related to divorce settlements involving monetary or property awards
Students
Even students must demonstrate financial legitimacy when transacting at scale:
- Two recent payslips
- Latest tax return
- Employment verification letter from part-time job or internship
- Bank statements reflecting wage deposits (within 3 months)
Acceptable Documents for Source of Funds
When it comes to specific transactions, acceptable proof varies by fund origin:
Salary Income
Same as above: payslips, tax returns, bank statements, and employer letters.
Sale of Assets
- Sales contract copy detailing transaction value and payout
- Most recent audited financial statements
Business Profits
- Latest audited financial reports
- Business bank statements (last 3 months)
- Recent corporate tax filings
- Third-party compliance certification
- Proof of ownership or equity stake

Funds from Decentralized Finance (DeFi)
With the rise of blockchain-based finance:

Personal Savings
Demonstrating savings requires tracing back to original income sources:

- Employment verification letters (position, dates, salary)
- Inheritance or gift documentation (if applicable)
- Court orders for spousal support or settlements
Frequently Asked Questions (FAQ)
Q: Why do platforms ask for proof of source of funds?
A: Financial platforms are required by law to comply with AML and KYC regulations. Verifying fund sources helps prevent money laundering, fraud, and terrorist financing.
Q: Can I use cryptocurrency gains as a valid source?
A: Yes. Exchange balance proofs, wallet transaction histories, and DeFi activity records are increasingly accepted—especially when linked to verified identities.
Q: How recent should my documents be?
A: Most institutions require documents dated within the last 3 months, especially bank statements and payslips. Tax returns and audited reports can be up to one year old unless otherwise specified.
Q: Do I need notarized documents?
A: Not always. Many platforms accept clear scanned copies. However, some high-value transactions may require notarization or official certification.
Q: What if my funds come from multiple sources?
A: You should provide documentation for each major source. For example, combine salary statements with sale-of-property contracts and investment summaries to build a comprehensive picture.
Q: Is there a difference between fiat and crypto platform requirements?
A: While core principles remain the same, crypto platforms often place greater emphasis on on-chain transaction history and exchange statements. Traditional banks focus more on payroll and tax documentation.
Best Practices for Submitting Documentation
- Ensure Clarity and Legibility: All documents should be high-resolution scans with readable text.
- Include Identifying Information: Make sure names, dates, and amounts are clearly visible.
- Maintain Consistency: Ensure dates and figures align across documents (e.g., deposit amounts match sale proceeds).
- Use Secure Channels: Only submit documents through official verification portals.
- Prepare in Advance: Have digital copies ready before initiating large transactions.
👉 Access a secure platform where source verification is fast, simple, and transparent.
