The payout you see is already after tax
When a lottery, sports-betting, or gaming operator pays out a win, the figure that hits your account is rarely the headline prize. The tax is taken at source, meaning the operator subtracts it before crediting you and forwards it to the revenue authority on your behalf. You never handle that slice yourself. This calculator reverses the question most winners actually have: given a gross win, what does the operator keep back, and what reaches me. The deduction is a withholding tax, the same family of advance taxes that applies to rent and contract payments, just pointed at gaming income.
Two rates sit behind the tool. A resident winner has 5 percent withheld, and a non-resident is charged 15 percent. Those are the rates this calculator applies. The 5 percent resident figure reflects the treatment of winnings as modelled here, while the 15 percent non-resident rate follows the entertainers and sportspersons band the data uses for visiting winners. Nigeria's 2025 tax reform is reshaping several withholding categories, so treat these as the modelled position and confirm the live rate with the FIRS, the Federal Inland Revenue Service, before assuming a specific number.
A NGN 1 million win, resident against non-resident
Say you win NGN 1,000,000. As a resident, 5 percent is withheld, which is NGN 50,000, and you walk away with NGN 950,000. A non-resident winning the same prize loses 15 percent, NGN 150,000, and receives NGN 850,000. Same ticket, NGN 100,000 difference, decided purely by where the winner is taxed.

The chart compares the net payout and tax withheld for the current inputs.
A word of realism: the prize an operator advertises is what you compute from here, but some platforms quote the post-tax figure already, and a few apply their own deductions on top, such as processing or transaction charges. The tool models the tax alone, so reconcile its net against what the operator actually states before assuming a shortfall is the taxman's doing.
Who this helps, and a misconception to drop
It suits casual bettors checking a single payout, regular players estimating the drag across many wins, and operators sanity-checking their deduction logic. The misconception worth dropping is that you must separately declare and pay tax on a win that was already withheld at source. For a typical resident punter, the 5 percent taken by the operator is generally the end of the matter for that income, not a down payment on a bigger bill later. If gaming is a genuine business rather than a hobby, the position differs, and that is where a word with the FIRS or your state internal revenue service earns its keep.
Winnings tax questions players ask
Is the tax on each win or on my net position after losses?
Withholding at source looks at the gross winning event, not your running balance. A 5 percent or 15 percent deduction applies to the amount paid out on a win, and losing stakes from earlier bets do not reduce that figure. Players who expect to net losses against wins for the withholding are usually disappointed.
Are small wins below a threshold left untaxed?
The structure here applies the rate to the payout without a built-in tax-free floor, so even modest wins can carry a deduction in principle. Whether an operator bothers to withhold on very small amounts is a practical matter, and the rules around thresholds are among the items the reform may adjust, so confirm the current treatment with the FIRS.
How is residency decided for the higher rate?
Residency for tax turns on your tax status in Nigeria rather than your nationality, broadly whether you are taxed here as a resident. A Nigerian living abroad and a foreign visitor can both fall on the non-resident side and face the 15 percent rate this calculator applies. If your status is borderline, the relevant revenue service can confirm which rate should apply.
