Source of funds (SOF) documentation is a core component of broker AML/CFT compliance frameworks across regulated forex brokers in 2026. The framework operates through threshold structures — basic deposits typically do not trigger enhanced SOF requirements, while substantial deposits or specific risk patterns trigger enhanced documentation. The specific thresholds and triggering patterns vary by broker and jurisdiction, with FCA-regulated, ASIC-regulated, and EU-regulated brokers operating under specific framework requirements that shape SOF practice.
For prospective customers planning substantial account funding, understanding the specific SOF framework supports advance preparation that prevents onboarding delays. The acceptable documentation patterns include bank statements, employment verification, business income documentation, investment income documentation, inheritance/gift documentation, and specific others depending on the customer's specific source of funds. Specific document quality, recency, and completeness matter substantially for SOF acceptance.
This piece walks through the specific SOF framework, the threshold structures, the acceptable documentation patterns, and the practical customer practice for substantial broker funding in 2026.
The Threshold Framework
How SOF triggering operates.
Basic deposit thresholds. Basic deposits below specific thresholds typically do not trigger enhanced SOF documentation. Specific thresholds vary; common patterns include $10,000-$20,000 or equivalent annually as basic threshold.
Specific cumulative aggregation. Cumulative deposits over time aggregate against specific thresholds. Multiple smaller deposits aggregating to substantial amount trigger enhanced framework.
Specific risk-based triggers. Specific risk-based triggers operate independent of nominal threshold. Specific patterns produce enhanced framework regardless of amount.
Specific jurisdiction-based triggers. Specific high-risk jurisdictions trigger enhanced framework.
Specific PEP-related triggers. PEP-related activity triggers enhanced framework.
Specific industry-based triggers. Specific high-risk industries trigger enhanced framework.
Specific specific other triggers. Specific other triggers based on broker-specific risk framework.
The combined trigger framework supports broker-side compliance.
Acceptable Documentation Patterns
Specific documentation that supports SOF.
Bank statements showing accumulated savings. Bank statements showing accumulated savings over specific period supports SOF for accumulated savings.
Employment income documentation. Salary statements, employment contract, specific employment verification supports SOF for employment income.
Specific business income documentation. Specific business income documentation including business bank statements, specific tax filings, specific other.
Specific investment income documentation. Specific investment account statements, specific dividend statements, specific other.
Specific property sale documentation. Specific property sale documentation supports specific property-sale-funded activity.
Specific inheritance documentation. Specific inheritance documentation supports inheritance-funded activity.
Specific gift documentation. Specific gift documentation supports gift-funded activity.
Specific specific other documentation. Specific other documentation for specific funding sources.
Specific multi-source combination. Multi-source funding may combine multiple documentation types.
The combined documentation framework supports specific source verification.
Comparison Across Major Broker Categories

| CySEC-regulated | Specific EU framework | Comprehensive EU documentation | Mature framework |
| FSA Seychelles | Specific international framework | Standard documentation | Established framework |
| FSCA-regulated | Specific SA framework | SA-specific documentation | SA-specific framework |
| Multi-jurisdiction | Variable | Variable | Specific framework |
The pattern shows specific framework alignment with regulatory framework.
