Crypto trading in Nigeria has come a long way  but as the space matures, so does the regulation. Starting in 2026, new national tax rules will require individuals to pay tax on profits from crypto transactions, with rates reaching up to 25% based on income brackets.

That means every trade, swap, or withdrawal could count toward your annual taxable income. And for many traders juggling multiple wallets and exchanges, calculating taxes manually can be confusing, time-consuming, and prone to mistakes.

That’s exactly why this free Crypto Tax Calculator was created  to make tax time less stressful. It helps you keep track of every trade, calculate profits or losses in Naira, and estimate how much you owe in just a few clicks.

Key Takeaways:

• Starting in 2026, the profits you make from buying and selling crypto in Nigeria will be taxed.

   

• The tax rate can be as high as 25%, depending on how much you earn.

   

• Keeping clear records of all your crypto transactions is now very important.

   

• The free Crypto Tax Calculator makes it easy to track your trades and stay on the right side of the law.

Features of an Easy Crypto Tax Calculator

A good crypto tax calculator shouldn’t make your life harder, or leave you in a confused state for  hours. It should be simple, clear, and easy to use  by Nigerian traders.

Here’s what makes it stand out:

• Supports Nigerian Naira (₦) – Every calculation is done in your local currency for easier tracking and accuracy with no  need to convert from USD or worry about fluctuating exchange rates.
• Uses local tax rates – The sheet automatically applies Nigeria’s crypto tax rules (currently 10%, soon up to 25% under the new regime), so you always know where you stand.
• Easy trade input – Just enter your buy and sell prices, dates, fees, and how long you held your assets the calculator will do the rest.
• Automatic profit and tax calculation – It instantly shows your capital gains, losses, and the estimated tax you owe.
• Printable reports for tax filing – At the end of the year, you can print or export your summary to attach to your FIRS filing or keep for your records.

Together, these features make crypto tax tracking less of a headache and more of a quick and easy way to handle your tax.

Common Challenges of Calculating Crypto Tax Manually

If you’ve ever tried to do it yourself, you’ve probably run into one or more of these:

• Different exchange rates: Prices vary between USD and NGN conversions on each platform.
• Trading fees: Fees eat into your profit, but they’re easy to forget.
• Missing data: P2P and wallet transfers aren’t always recorded properly.
• No clear FIRS format: There’s no official crypto tax form yet, so everyone’s guessing.

The CubEx Crypto Tax Calculator helps you bypass these struggles by doing the math for you.

Tips for Maximizing Tax Savings and Staying Compliant

Here are some simple but effective tips  that can help you:

• Keep detailed records all year round – Don’t wait until tax season, always record every trade, deposit, and withdrawal as it happens. It saves you from confusion later.
• Offset your losses against profits – If you made a loss on one crypto and a gain on another, you can balance them out within the same tax year to reduce your taxable amount.
• Stay updated on tax changes – Nigeria’s crypto tax laws are still evolving. Keep an eye on updates or verified reports from reliable sources so you always know the current rates and requirements.
• Ask for professional help when needed – If you trade often or earn from multiple sources (like staking or NFTs), it’s wise to talk to a registered tax expert. A short consultation can save you from big errors later.

Small steps like these can help you protect your profits, avoid penalties, and trade with complete ease.
