Who suppose declare winnings, and wetin di law talk (for short)
Any winnings wey come from lottery, gaming, betting, or even reality shows like Big Brother Naija-type dey fall under di Deduction at Source (Withholding) Regulations 2024 — a regulation wey federal government gazette on 2 October 2024 and wey start work from 1 January 2025. Under dis regulation, winnings wey belong to tax-resident individual dey attract 5% withholding tax, while non-resident dey pay 15%. Both rate dey apply to your NET winnings — na wetin you win minus your stake, no be di full amount wey land your account.
From 1 January 2026, di 2025 tax-reform package don full enter force: di Nigeria Tax Act 2025 and di Nigeria Tax Administration Act 2025. Under di Nigeria Revenue Service (Establishment) Act 2025, di old FIRS change name go Nigeria Revenue Service (NRS) — so if you see “NRS” for any tax document from 2026 go, na di same body wey used to be FIRS.
Now here be di part wey confuse plenty people: WHERE you go file no be di same for everybody. If you be resident individual, your personal income tax dey filed with your STATE revenue service — LIRS if you dey Lagos. But if you be FCT resident, non-resident, or you dey file for company, na di NRS (wetin used to be FIRS) go handle your matter. Mix up dis one, and confusion go follow you throughout di whole process — so make sure you sabi which basket you fall inside before you begin.
Resident vs non-resident — which rate concern you
If Nigeria be your tax home — meaning say you dey ordinarily reside for Nigeria and your centre of economic life dey here — na di 5% rate concern you. If you no be resident (maybe you dey live abroad but you still get Nigerian betting account you dey use), na di 15% rate go apply to your winnings instead. If you no too sure which category you fall under — especially if you dey shuttle between Nigeria and abroad — no guess am. Confirm your residency status with a tax professional before you file, because di wrong assumption fit cost you.
How to declare gambling winnings tax for Nigeria, step by step
Forget di long grammar — how to declare gambling winnings tax in Nigeria dey come down to six practical steps. Follow dem in order, and by di time you reach Step 6, your paperwork go dey correct and your mind go dey rest.
Step 1 — Gather di records wey you get
Before you begin anything, collect your winning slip or bet-slip ID, your casino transaction reference, and every payment or withdrawal confirmation — bank alert, OPay alert, PalmPay alert, whichever one apply to you. Note down di dates, and write down di operator name plus wetin kain licence dem carry (state-licensed or offshore). Screenshots and account statements dey count as evidence too, so no delete dem.
Step 2 — Work out your gross and net winnings
Your net winnings na di amount you won minus your stake — and na dis net figure di withholding tax dey land on, not di full gross amount. Make dis clear with a small example:
| Item | Amount |
|---|---|
| Stake | ₦500 |
| Gross win | ₦50,000 |
| Net winnings (win minus stake) | ₦49,500 |
| 5% withholding tax (resident rate) | ₦2,475 |
| Wetin you carry go (net payout) | ₦47,025 |
You no need do dis maths by hand every time — use a withholding tax calculator to run your own numbers quick quick, especially if your stake pattern dey different from dis example.
Step 3 — Lagos-licensed payout: dem don usually comot di WHT already
From February 2026, Lagos-licensed operators begin enforce automatic deduction for payout — dem dey remit di 5% straight to LIRS before di money even reach your account. So if you play for a state-licensed platform like Bet9ja (mentioned here only as an example, no be recommendation), check your payout or transaction history first: if wetin land your account na di net figure already, di 5% don already handled for source. Keep or request di deduction record — di operator statement or di LIRS-side receipt — as your proof, because you generally no dey pay am twice.
Step 4 — Offshore winnings: declare am for your annual return (Form A)
Offshore operators — Curaçao, Anjouan, MGA-licensed sites and di rest — no get any automatic deduction mechanism wey dey remit tax on your behalf. So if na from one of dis platforms you win, di responsibility land for your own hand: you go self-assess. Enter di winnings as income for your annual self-assessment return — Form A (di Taxpayer Self-Assessment Form, wey you fit download from your state IRS) — under di worldwide-income rule wey di 2025 tax regime carry over. If you win for USDT or any other crypto from an offshore site, still record di naira value for di time you receive am.
Step 5 — File with di correct authority, before di deadline
Resident individuals dey file Form A with dia STATE revenue service — LIRS if you be Lagos resident — on or before 31 March each year, for di previous year income. If you be FCT resident, non-resident, or you dey file for a company, na di Nigeria Revenue Service (NRS/FIRS) go handle your case instead. E-filing dey available too: LIRS e-Tax for Lagos state cases, or TaxPro-Max for federal NRS/FIRS cases. Once you file, settle any balance wey remain.
Step 6 — Keep your records for 5 years
No throway your slips, statements, deduction receipts, or di return wey you file — keep dem for at least 5 years. Dis matter for SCUML, NFIU, and general AML compliance, plus any source-of-funds (SoF) review wey fit come your way, especially since CBN and EFCC dey monitor fintech accounts wey dey feed offshore betting closely. Good records na your defence if anybody ever question where your money come from.
Special cases wey fit meet you
Whether your winnings come from casino, sportsbook, lottery, or poker, di same 5%/15% framework and di net-winnings basis dey apply across board — so a big casino jackpot and a football acca dey taxed di same way, just di source dey different. Even reality-show type winnings — Big Brother Naija prize money and di rest — dey fall under di same “winnings” head, so treat dem di same way you go treat betting winnings.
If your year mix onshore and offshore winnings together — say you win small for a Lagos-licensed platform and bigger for an offshore site — declare di offshore portion for your return, and keep di deduction proof for di onshore side separate. And if an offshore site pay you for USDT or any crypto, e still count as income: record di naira value for di time you receive am, and remember say di AML/source-of-funds exposure dey higher for crypto payout, so keep extra documentation for dat one.
Common mistakes wey you suppose avoid
Plenty player dey mismanage dis process, and na small mistake dey cause big wahala later. Watch out for dese:
- To assume say all your winnings dey tax-free — dem no be.
- To double-count withholding tax wey dem don already comot for source, and pay am again.
- To forget offshore winnings completely because “nobody deduct am automatically.”
- To throway your slips and statements before di 5-year mark reach.
- To mix up di filing authority — sending your return to di wrong place (state IRS versus NRS/FIRS).
- To declare di gross amount instead of di net winnings, and overpay yourself for confusion.
Wetin to carry go
For most resident player wey dey use Lagos-licensed platform, how to declare gambling winnings tax in Nigeria don already start before you even do anything — di 5% withholding tax dey taken for source, so your job na to verify di deduction and keep your records straight. But offshore winnings na different matter entirely: na you go self-declare am on your annual Form A return with your state revenue service — LIRS if you dey Lagos — or di NRS if you be FCT resident or non-resident. Whichever category you fall under, keep everything — slips, statements, receipts, and your filed return — for at least 5 years.
