Tax on trading in your country

Tax authorities treat trading profit as income, not as a windfall. In Nigeria, the Federal Inland Revenue Service (FIRS) handles companies, while your state internal revenue service handles personal income. The type of income matters because it affects how you report it. For individuals, trading profit is usually added to other income, such as salary or business earnings. That total then determines your tax rate.

If you trade through a company, the company pays tax on its profits. If you trade as an individual, your profit is part of your personal income. The rate you pay depends on your total income for the year. A small profit may fall below the threshold where tax starts. That threshold varies, so check with a Nigerian tax professional.

The law does not care whether you call trading a hobby or a business. What matters is whether you are making profit regularly. If you trade often and aim to make money, the tax authority may treat it as a business. That means you must report it. Keeping records from the start helps you show what you earned.

Start by saving every broker statement. Download a monthly statement and keep it in a folder, either on your computer or in the cloud. These statements show your trades, fees, and the naira value at the time. Without them, you cannot prove what you earned or what you spent. The tax authority may ask for them if they review your income.

Record every deposit and withdrawal in naira. Note the date, the amount, and the exchange rate used. If you deposit ₦100,000 and later withdraw ₦150,000, the difference is not all profit. You need to track the trading results in between. Also record commissions, spreads, and swap fees. These costs reduce your profit, so they lower your tax.

Keep a simple spreadsheet or a notebook. List each trade with the date, the instrument, the lot size, the profit or loss in naira, and any costs. At the end of the year, add up your net profit. That figure is what you report. If you are unsure, ask a Nigerian tax professional. Do not rely on what another trader tells you.

Your taxable profit is not the same as your gross profit. You can subtract the costs of trading, such as commissions and spreads. In the example on this page, a ₦65,100 gross profit became ₦58,760 after ₦2,000 commission and ₦4,340 spread. That lower figure is what you report. So every cost you record reduces the amount tax is calculated on.

Brokers may charge swap or overnight fees if you hold a position past a certain time. They may also round pip values or use a different exchange rate when converting to naira. These details change your final profit. Check your broker's terms to know exactly what they charge. Then record those charges as they happen.

If you trade frequently, these costs add up. A small difference in the exchange rate can change your naira profit by thousands. That is why you should record the rate you actually got, not an estimate. Your broker's statement will show the exact amounts. Use those figures, not memory.
