Structuring vs Smurfing: What is the Difference?
In brief: Structuring breaks activity into smaller parts to avoid scrutiny, while smurfing uses multiple people or accounts to do that at scale.
Key points
- Structuring is the deliberate splitting of transactions, payments, or activity to avoid attention.
- Smurfing is a form of structuring that uses multiple people, accounts, or entities.
- For accountants and law firms, the key risk is repeated activity that appears designed to avoid normal checks.
Structuring vs smurfing in plain English
Structuring means deliberately splitting activity into smaller transactions or steps to avoid checks, thresholds, questions, or detection. Smurfing is a type of structuring where multiple people, accounts, branches, businesses, or wallets are used to spread the activity.
The concepts are often discussed in banking, but they matter for professional firms because they can appear in source-of-funds explanations, bookkeeping records, client accounts, company structures, and repeated instructions.
How structuring can appear in professional work
Examples include:
- Several payments just below an internal approval or review threshold.
- A client splitting fees or retainers across unrelated accounts.
- Multiple small injections of capital instead of one explainable transfer.
- Invoices broken into smaller amounts with no operational reason.
- Repeated small transactions that do not fit the client profile.
The question is whether there is a legitimate business reason or whether the pattern appears designed to avoid scrutiny.
How smurfing can appear
Smurfing usually adds a network element:
- Multiple individuals contribute funds for one client without a clear relationship.
- Several companies make similar payments to the same beneficiary.
- A group of connected people move money through personal and business accounts.
- A client uses friends, family, employees, or associates to receive and pass on funds.
For a regulated firm, the risk increases when the client cannot explain why these people or entities are involved.
What to ask
Use simple, proportionate questions:
- Why was the activity split?
- Who controlled the funds at each point?
- What is the relationship between the parties?
- What documents prove the commercial purpose?
- Does the pattern match the client's profile and risk rating?
- Has the client avoided ordinary AML checks?
Evidence checklist
Depending on risk, keep:
- Bank statements showing the route of funds.
- Contracts, invoices, or loan agreements.
- Ownership and control records.
- Source-of-funds and source-of-wealth evidence.
- Notes explaining why the split activity is legitimate or why it was escalated.
- MLRO or nominated officer decision records.
When to escalate
Escalate when the pattern appears artificial, the explanation changes, the client avoids checks, or the evidence does not support the stated purpose. A firm does not need certainty before escalating internally. Suspicion can arise from inconsistent facts and unexplained behaviour.
