The question wey plenty Naija punters dey ask before dem move big money — what Nigerian banks report to NFIU — get answer wey dey inside statute, no be rumour. Under the Money Laundering (Prevention & Prohibition) Act 2022, your bank must file a Currency Transaction Report for any cash transaction wey pass ₦5,000,000 for individual account and ₦10,000,000 for corporate body. A Suspicious Transaction Report na different matter entirely: no minimum amount dey, and e must reach the Nigerian Financial Intelligence Unit within 24 hours.
Three bodies dey run this system and dem no dey do the same work. SCUML register and supervise the businesses wey must report. The NFIU collect the reports and pass intelligence to enforcement agencies. FIRS — now the Nigeria Revenue Service under the Nigerian Tax Act 2025 — plus your State Internal Revenue Service dey handle tax. Reporting itself no be accusation; na routine compliance. But large or out-of-pattern flow dey visible, and e fit carry consequence.
This guide na independent educational resource. E explain wetin each agency dey do, the thresholds wey trigger a report, the tax layer wey touch player winnings, and the paperwork wey suppose dey ready before you send big money go any offshore operator.

Who dey watch the money: SCUML, NFIU and FIRS explained
Naija AML/CFT framework share the work across three separate bodies, and mixing dem up na the most common mistake person dey carry go bank. The order dey sequential, no be overlapping: SCUML supervise the entities wey must report, the NFIU receive and analyse wetin dem file, and the Nigeria Revenue Service plus the State Internal Revenue Services collect tax. None of the three fit freeze your account by itself — that one need EFCC and, for practice, a court order.
SCUML and the EFCC — registration and monitoring
SCUML stand for Special Control Unit Against Money Laundering, and e dey operate as a unit under the Economic and Financial Crimes Commission. Im job na to register and supervise Designated Non-Financial Businesses and Professions — DNFBPs — wey include accountants, lawyers, estate agents, dealers for precious metal, and licensed gaming operators. SCUML dey run compliance inspection on dem and dey refer case go EFCC where enforcement need to follow.
For an ordinary punter, SCUML role na indirect: you no dey register with SCUML and you no dey file anything to dem. But the licensed operator wey dey hold your money na DNFBP under SCUML supervision, so e carry im own customer due-diligence duty — and that duty na wetin dey produce report wey later reach the NFIU.
The NFIU — where the reports actually land
The Nigerian Financial Intelligence Unit na the central hub for financial intelligence for the country. Banks, fintechs, microfinance institutions and DNFBPs all dey file dem Currency Transaction Reports and Suspicious Transaction Reports to the NFIU. From there the NFIU dey analyse the data and share intelligence with the competent authorities — the EFCC first among dem — wey get power to investigate.
Important distinction: the NFIU no dey investigate and e no dey prosecute — e dey collect, analyse and pass on. So a report wey land there no mean say enforcement dey come tomorrow morning. Consequence dey arrive when the NFIU pass the intelligence go an enforcement agency and that agency decide to move.
Wetin your bank must report: what Nigerian banks report to NFIU as CTR and STR
Two instruments carry almost all the weight for a punter account: the Currency Transaction Report and the Suspicious Transaction Report. Both sit on the Money Laundering (Prevention & Prohibition) Act 2022 (section 7) and the Terrorism (Prevention & Prohibition) Act 2022 (section 84), with the operational detail for the NFIU STR Guidelines of 13 December 2024. The two run on different logic — one na threshold, the other na behaviour.
| Report type | Threshold | Filed to | Timeframe |
|---|---|---|---|
| Currency Transaction Report (CTR) | Above ₦5,000,000 (individual) / above ₦10,000,000 (corporate body) | NFIU (DNFBPs route through SCUML) | Within the prescribed filing window |
| Suspicious Transaction Report (STR) | No minimum — any amount at all | NFIU | Within 24 hours of the suspicion arising |
Currency Transaction Report — the ₦5 million and ₦10 million lines
Under section 7 of the MLPPA 2022, a bank or DNFBP must file a CTR with the NFIU for any cash transaction wey pass ₦5,000,000 for individual customer or ₦10,000,000 for corporate entity. The filing na mandatory and non-discretionary. Nobody dey sit down to judge whether the money look suspicious — the threshold alone dey trigger the duty, and the compliance officer no get discretion to skip am.
The part wey dey catch people na the aggregation rule. Structuring — breaking one big amount into plenty smaller transfer so e go stay under the line — na itself reportable and unlawful under the Act, and monitoring systems dey calibrated to add linked transfers together. Person wey push ₦2,000,000 every week for four weeks no dey below the threshold in any way wey protect am; that exact pattern na wetin the rule dey there to catch.
Suspicious Transaction Report — no minimum, and a 24-hour clock
The STR no get floor at all. Any transaction, any size, wey make a compliance officer form suspicion of money laundering, terrorism financing or unusual activity must reach the NFIU within 24 hours of that suspicion arising. The NFIU STR Guidelines of 13 December 2024 set out the behavioural indicators: transaction wey no match the customer declared income profile, sudden big transfer after long quiet period, or repeated international transfer wey no get clear reason behind am.
For a bettor, the 24-hour window mean say your bank compliance desk fit act the same business day. And because size no dey matter for STR, na this instrument — no be the CTR threshold — wey most likely go touch a player whose deposits to an offshore operator no gree match wetin im declared income fit carry. A ₦150,000 transfer fit generate STR while a ₦4,900,000 one dey pass quietly, depending on the profile.
The tax layer: FIRS betting tax, the Nigeria Revenue Service and your winnings
The Nigerian Tax Act 2025 enter into force on 1 January 2026 and restructure the federal tax authority. The Federal Inland Revenue Service now dey formally known as the Nigeria Revenue Service, even though the FIRS name still dey common for everyday use. Gaming and lottery companies now fall inside the general NTA framework instead of a separate sector regime. But the point wey concern you as player na this: withholding tax on winnings na State Internal Revenue Service business, no be federal.
Tax wey dem withhold at source for your winnings (Lagos 5%)
Lagos State dey enforce 5% withholding tax on the net winnings of Nigerian-resident players, and 15% for non-residents, from February 2026. The licensed operator dey deduct am at source before the payout land for your account, then remit am to the Lagos Internal Revenue Service. So a Lagos-resident player wey win ₦100,000 net go collect ₦95,000 after deduction. Other states dey expected to bring similar frameworks as the 2026 gaming-tax overhaul spread, but the timeline dey differ state by state.
Separate from that, licensed operators dey face a gross gaming revenue tax framework — reported around 11% under the 2026 overhaul, though the final position still dey settle. That one na operator obligation; e no dey show as extra deduction for your payout slip.
Offshore operator and your own tax exposure
Offshore betting sites wey register outside Naija usually no dey withhold any Nigerian tax at source. That absence no cancel your domestic obligation, and e definitely no cancel the bank reporting. When big offshore winnings enter a Nigerian account, two systems dey look am at once: bank AML monitoring and tax-authority data-matching. Where the amount big relative to declared annual income, talk to a qualified tax adviser before you repatriate am, no be after query don land.
Wetin actually dey trigger a flag (and the 2024 account freezes)
Beyond the written CTR and STR rules, some operational patterns dey pull heavy attention from banks, fintechs and the EFCC. For a Naija punter these ones dey bite faster than the statutory thresholds, because dem dey run on automated monitoring wey no need human to press button first.
Fintech wallets and automatic monitoring
OPay, PalmPay and Moniepoint na regulated entities wey carry the same NFIU reporting duty as deposit-money banks, and dem transaction-monitoring systems dey flag large or unusual outflow automatically. Wallet holder wey dey receive repeated inbound transfer and dey route the bulk of am go offshore betting site within short window dey show exactly the shape wey the system dey look for — whether each single transfer stay below ₦5,000,000 no dey change that.
Card rails don already tighten. International Mastercard and Visa transactions on merchant category code MCC 7995 dey blanket-blocked at GTBank, Access, Zenith, UBA, First Bank, Wema, FCMB, Stanbic IBTC and Kuda. That block no be an NFIU reporting trigger by itself, but e push plenty offshore deposit traffic go wallet and crypto rails — and both of those carry dem own monitoring exposure.
The April 2024 freezes — wetin dem show
For April 2024 the EFCC obtain a Federal High Court order freezing accounts wey dem link to illicit forex and crypto peer-to-peer flow. The initial announcement mention around 300 accounts; as the investigation widen, the figure reach 1,146 accounts. Dem freeze the accounts pending investigation — no conviction dey at that stage — but the episode show how fast an unusual crypto-P2P or forex pattern fit climb from automated monitoring go court-ordered restriction within weeks.
The USDT and crypto-P2P channel, wey become the main rail for offshore gambling deposit after the card blocks land, don dey draw direct CBN and EFCC attention since 2023. Binance NGN P2P market itself dey suspended from February 2024 following those same concerns. Anybody wey still dey lean on crypto-P2P for offshore funding dey operate inside a segment under heightened scrutiny.
Practical: source of funds documentation and source of wealth
The single most useful thing a player fit do before a big offshore deposit na to arrange clean paperwork ahead of time. Banks and operators dey apply Enhanced Due Diligence to large or out-of-profile transaction, and when that query land, the person wey already get im documents together dey settle am for days instead of weeks.
Source of Funds (SoF) na the origin of this particular money — the salary, business revenue or asset sale wey this specific deposit come from. Source of Wealth (SoW) na the bigger question of how your overall net worth build up over time. Compliance officer wey ask for SoF wan know where this ₦5,000,000 come from; operator wey dey apply EDD to a high-value account fit also wan understand the position wey make that kind deposit make sense repeatedly. Under the MLPPA 2022, records dey kept for at least five years, so consistency across years matter.
Wetin paperwork to keep before a big deposit
| Document | Wetin e dey prove | How far e suppose cover |
|---|---|---|
| Pay slips | Gross salary, employer identity and PAYE deduction — confirm employment SoF | Three months minimum |
| Bank statements | Balance history and inflow pattern wey match the declared SoF | Three to six months |
| CAC registration certificate | The legal entity wey business income dey come through (self-employed and business owners) | Current registration |
| Tax returns / tax clearance certificate | Income wey you don declare to your State IRS and the NRS — e connect SoF to formal tax record | Most recent filed year |
Keep the four of dem for one organised file and make sure the figures gree with each other. Discrepancy between wetin pay slip talk and wetin bank statement show na one of the most common reasons a routine query dey escalate into full review.
How to keep am clean and consistent
Structuring — splitting transfer to sit under the CTR line — na reportable behaviour under the MLPPA 2022 on top of being unlawful, so e no be strategy, e na exposure. Moving another person money through your own account create a profile wey look exactly like money-mule activity no matter your intention, and modern monitoring dey catch that pattern reliably.
Where big deposit dey planned, e dey wise to tell your primary bank before the money move, provide the SoF documents upfront, and answer any compliance correspondence sharp and complete. Slow or half answer na wetin dey turn a small clarification request into an STR filing inside that same 24-hour window.
Conclusion
What Nigerian banks report to NFIU dey set with statutory precision: Currency Transaction Reports for cash transactions above ₦5,000,000 (individuals) or ₦10,000,000 (corporate bodies), and Suspicious Transaction Reports for any amount at all, filed within 24 hours of the suspicion arising, under the Money Laundering (Prevention & Prohibition) Act 2022. On top of that sit the tax layer — the Nigeria Revenue Service federally, and your State Internal Revenue Service for winnings, wey Lagos dey enforce as 5% WHT on resident net winnings (15% non-resident) from February 2026.
For the player, the practical position dey simple. Clean, consistent paperwork — pay slips, bank statements, CAC registration and tax clearance — kept ready before any big offshore deposit na the strongest protection against a compliance hold, as the April 2024 EFCC court-ordered freezes wey reach 1,146 accounts show. Structuring transfers to duck a threshold na itself reportable and unlawful. Transparency wey get paper trail behind am na wetin the framework dey built to reward.
