Nigeria Crypto Tax Calculator 2026

Worried about how much tax you might owe on your Bitcoin, Ethereum or other digital assets in Nigeria after January 2026? Enter buys, sells and fees to get your capital gains, deductible costs and a clear CGT estimate you can use to plan ahead.

How do I calculate crypto capital gains in Nigeria

Enter proceeds, acquisition cost and all fees. The calculator subtracts costs from proceeds to find your gain, then applies your chosen allowance and rate to estimate tax.

What tax rate should I use for 2026

Enter the rate you expect to apply to capital gains on digital assets, or a custom rate if you are taxed as trading income. The rate field is editable so you can match advice from your accountant.

Do I pay tax if I only swap one coin for another

Swaps are treated like disposals. Use the fair market value of what you receive as the proceeds in the calculator.

Are network fees and exchange fees deductible

Yes. Add gas, exchange fees and reasonable costs of acquisition or disposal to the fee fields so they reduce your gain.

What tax applies to crypto in Nigeria

Gains on the disposal of digital assets can be treated as chargeable gains. The calculator lets you set the applicable rate and shows the maths for full transparency.

What counts as a disposal

Selling for cash, swapping one token for another or withdrawing into a form where you realise value can all be disposals. Each disposal can create a gain or a loss.

Which cost-basis method should I choose

If you do not have a set policy, Average Cost is the simplest for personal use. FIFO is common and easy to justify. Pick one method and use it consistently.

How do I enter fees and gas

Add exchange fees, agent charges, network gas and withdrawal fees in the buy or sell fields. These reduce your gains by increasing cost or reducing proceeds.

I trade in dollars. How do I handle FX

Enter the USD amounts and the naira exchange rate for the date of the transaction. The calculator multiplies to convert everything to naira for the tax estimate.

Can I offset losses

Yes. Enter your carried-forward crypto losses and the tool will net them against current gains. The estimate shows the chargeable gain after losses.

Does the calculator handle P2P cash-outs

Yes. Include the agent fee and the naira received. That is your sale proceed for the disposal calculation.

What if I only sold part of my holdings

Choose FIFO, LIFO or Average Cost and enter the units sold. The calculator computes the matched cost basis for the exact amount you disposed of.

Is there different tax for short-term and long-term

Policies can change. The tool uses a single rate by default. If different rates apply by holding period in the future, adjust the rate or run two scenarios.

Is this legal advice

No. It is an educational estimate to help you plan. Always confirm your figures and any filing duties with a qualified tax adviser.

Can I use this if I am in the diaspora

Yes. You can model sales while resident in or outside Nigeria by selecting your residency status and setting the rate or rules that match your situation.

How do swaps get taxed

A swap is treated as selling the asset you give up and buying the asset you receive. Enter the fair value and fees so the tool can calculate the gain on the asset disposed of.

What records should I keep

Keep wallet addresses, exchange statements, CSV exports, screenshots of rates and fees, bank or P2P receipts and any notes that explain your transactions.

Can I export the results

You can copy the summary into your notes or share it with your accountant. If you maintain a spreadsheet, the figures map directly to gain, losses and tax columns.

What rate should I use

Use the rate you reasonably expect to apply based on current guidance. The field is editable so you can run conservative and worst-case scenarios.

How do I handle airdrops or forks

Record a cost basis for the units. When you dispose of them, enter proceeds, your chosen basis and fees. The calculator will estimate the gain.

What if I made a loss

If your gain before relief is negative, the calculator shows a loss and zero tax. Keep good records so you can discuss any relief or carry rules with your adviser.

Which cost-basis method should I pick

Common methods are FIFO, LIFO and Average Cost. This version applies the method you used when entering the numbers. For multi-lot portfolios, repeat per lot and add up.

Does residency matter for crypto tax

Yes, residency can affect your overall tax position. This tool includes simple residency context fields and keeps your calculation transparent for professional advice.

How do I treat crypto received as salary

If you are paid in crypto, convert to naira at receipt to measure income. When you later dispose of the coins, calculate any gain or loss from that basis. Use the custom rate if your activity is taxed as income.

When is tax due

Use the result to plan cash set-asides for statutory payment timelines. Always confirm deadlines with current guidance or your accountant.

Do stablecoins attract tax when I sell to naira

Yes, if you dispose of units at a value different from your cost, the gain or loss is calculated the same way.

Can I net fees across multiple trades

Yes. For a single disposal, enter the total fees linked to that transaction. For many trades, run each disposal and sum the results.

What records should I keep

Keep wallet addresses, exchange statements, transaction hashes, screenshots of prices, fee receipts and bank settlement records.

Will this calculator be updated if rules change

Yes. NGDrives Tools connects content to forms through ACF and a custom CPT, so rates and text can be updated quickly as guidance evolves

Worked examples

Example 1 Average Cost single sale

Bought 0.5 BTC at ₦18,000,000 with ₦90,000 fees
Bought 0.3 BTC at ₦13,000,000 with ₦65,000 fees
Total cost = ₦18,090,000 + ₦13,065,000 = ₦31,155,000
Total units = 0.8 BTC
Average cost per BTC = ₦31,155,000 ÷ 0.8 = ₦38,943,750

Sell 0.4 BTC at ₦52,000,000 per BTC with ₦80,000 fee
Sale value = 0.4 × ₦52,000,000 = ₦20,800,000
Net sale = ₦20,800,000 − ₦80,000 = ₦20,720,000
Cost basis = 0.4 × ₦38,943,750 = ₦15,577,500
Gain = ₦20,720,000 − ₦15,577,500 = ₦5,142,500
If the CGT rate is 10 percent
Estimated tax = ₦5,142,500 × 0.10 = ₦514,250

Example 2 FIFO with loss carryover

Buys

1,000 USDT at ₦1,450 per USDT fee ₦5,000 cost ₦1,455,000
1,000 USDT at ₦1,520 per USDT fee ₦5,000 cost ₦1,525,000

Sell 1,500 USDT at ₦1,600 per USDT fee ₦7,500
FIFO cost basis uses the first 1,000 from the first lot and 500 from the second lot
Cost basis = (1,000 × ₦1,450) + (500 × ₦1,520) + proportional fees
= ₦1,450,000 + ₦760,000 + fees ₦7,500 buy side already included above
Sale value = 1,500 × ₦1,600 = ₦2,400,000
Net sale = ₦2,400,000 − ₦7,500 = ₦2,392,500
Total buy cost used = ₦1,455,000 + 0.5 × ₦1,525,000 = ₦2,217,500
Gain before losses = ₦2,392,500 − ₦2,217,500 = ₦175,000
Loss carryover entered = ₦50,000
Taxable gain = ₦175,000 − ₦50,000 = ₦125,000
At 10 percent
Estimated tax = ₦12,500
