Tax on trading in your country

A trader who keeps a monthly statement file can answer a tax question in minutes. A trader who does not may spend weeks rebuilding the year. The difference is not talent. It is whether the paperwork was saved on the day it arrived.

The first trader downloads the broker statement on the first day of each month. The file is named with the month and year. A simple sheet records each closed trade: date opened, date closed, instrument, size, profit or loss in KSh, and any fee. The second trader relies on memory and a phone full of M-Pesa messages.

When the first trader is asked about a KSh 30,000 gain, the answer is already in the sheet. The second trader has to guess, and guessing is where errors start. The tax office does not need perfection. It needs a figure that can be explained.

In Kenya, the authority that wants to hear about trading results is the Kenya Revenue Authority. The regulator for the brokers themselves is the Capital Markets Authority, or CMA. The CMA supervises the firms. The tax authority deals with your personal tax position.

Trading gains are generally treated as income, but the exact label depends on your situation. For some people it is business income. For others it is an investment gain. The label matters because it decides which form you use and when you file. The rules can change, so confirm the current position with the tax authority or a qualified tax adviser.

You do not need to know every rule today. You need to know who to ask and what to keep. The records you save now are the evidence you will use later. Without them, even a correct rule is hard to apply.

Start with the broker statement. Download it every month, even in months with no trades. Save it as a file, not a screenshot. A screenshot cannot be searched, and it often misses the fee lines.

Next, keep a simple sheet with one row per closed trade. A closed trade is one that has been opened and then closed. Open trades are not yet a result. The row should show the date, the instrument, the size, the profit or loss in KSh, and any commission or swap charge.

Finally, keep the funding records. If you sent money by M-Pesa or bank transfer, save the confirmation. If you withdrew money, save that too. These records show the movement of your own money, which is separate from trading profit or loss. They answer the question of where the money came from and where it went.

Open a second account for trading alone. Fund it from your main account in one clear transfer, and write down the date and the amount. When you withdraw, do the same in reverse. This single habit turns a year of mixed payments into a short list of entries you can match against statements.

Pay broker costs from the trading account, not from your household budget. Deposits, withdrawals, commissions and swap charges then sit in one place, and the balance tells its own story. If you move KSh 40,000 in and later withdraw KSh 46,000, the difference is KSh 6,000, and you can point to the trades behind it. Mixing the two accounts hides that difference among rent, fuel and groceries.

Keep the account in your own name and in shillings where your broker allows it. A joint account or a friend's M-Pesa line makes ownership hard to show later. If your broker only settles in another currency, note the rate used on each transfer, because the shilling figure moves even when the trade does not.

Review the two accounts once a month. Check that every deposit and withdrawal appears in both your sheet and the broker statement. Fix any gap while the month is fresh, not in the following year.

A gain that arrives in your M-Pesa wallet feels like a bonus. A gain recorded in a ledger looks like income. The difference matters when a lender, a landlord or the revenue authority asks what you earned. Treat trading results as a small business activity, not as a lucky transfer from a friend.

That framing changes three habits. You date every deposit and withdrawal, you label each one as capital added or profit taken out, and you never mix the two. A KSh 20,000 withdrawal is not a KSh 20,000 gain if KSh 15,000 of it was money you put in earlier. Without labels, the two are indistinguishable a year later.

Keep a running figure for capital contributed. Add every deposit to it. When you withdraw, decide whether you are reducing capital or taking profit, and write which one beside the entry. The record stays honest because each row is decided at the moment it happens, not guessed afterwards.

This habit also answers the question every beginner eventually faces: how much of the balance is mine to spend. If capital contributed is KSh 80,000 and the account holds KSh 95,000, the difference is not all profit until you account for charges already deducted. The sheet shows the gap plainly.
