For most people, the answer is no. IRAS says gains from selling shares in Singapore are “generally not taxable”, because buying and selling shares is “generally viewed as personal investments.” The word that matters is “generally”. If your buying and selling looks like a business, IRAS can treat the profit as income and tax it.
IRAS decides that case by case, using a set of tests often called the badges of trade. This post quotes what IRAS says, lists the 8 badges, and shows what each one asks. It is general education, so for your own position, check with IRAS or a tax adviser.
What does IRAS say about gains from shares?
The plain answer sits on IRAS’s page about what is taxable for individuals. It says: “Gains from the sale of a property, shares and financial instruments in Singapore are generally not taxable.”
Then it is more specific. “Profits or losses derived from the buying and selling of shares or other financial instruments (including digital tokens) are generally viewed as personal investments.”
On that same page, IRAS also says “You do not need to declare gains that are not taxable in your Income Tax Return.” So most people who buy and sell shares in their own name report nothing about those gains.
A reader on r/singaporefi summed up the confusion well in January 2025: “a purely hypothetical question regarding trading income got me curious, but I can’t find any answers in Singapore’s context.” The rest of this post is that answer, in IRAS’s own words.
When can trading profits become taxable?
When the activity looks like a trade, in the tax sense. IRAS’s page for companies explains the idea: “The word ‘trade’ is not defined in the Income Tax Act 1947. Whether a trade is being carried on is a question of fact.”
The pages name no single test and no trade count that tips you over. IRAS says “All the factors are taken into consideration when determining whether a trade exists, and no single factor is conclusive.”
Its page for individuals lists 4 criteria, written for property: “Frequency of transactions”, “Reasons for buying and selling”, “Financial means to hold the property for long term”, and “Holding period.” The individual page gives no separate list for people who trade shares. The same questions of frequency, motive and holding period are the natural place to start, but only IRAS can say how they apply to you.
What are the 8 badges of trade?
These are the 8 factors IRAS lists on its page about whether a trade exists. They are written for companies, and the quotes below are IRAS’s own words.
| Badge | What IRAS says | What it looks at |
| 1. Nature of subject matter | Some assets “are normally regarded as the subject of trading” | Whether the asset is one people usually trade |
| 2. Length of ownership | “The shorter the holding period, the more likely it is regarded as held for trading.” | How long you usually hold |
| 3. Frequency of transactions | “A high frequency of similar transactions is more indicative of trading than an isolated transaction.” | How often you buy and sell |
| 4. Supplementary work | Work done “to make it more marketable or extra effort made to find or attract purchasers” | Any extra work you do to sell |
| 5. Circumstances of the realisation | A forced sale or “sudden urgent need of cash” is “less likely to be indicative of trading” | Why you sold |
| 6. Motive | “whether there was an intention to trade at the time of the acquisition” | What you intended when you bought |
| 7. Mode of financing | “Short-term financing is more indicative of trading than long-term financing.” | How you paid for it |
| 8. Other factors | Records, accounting treatment and “other evidence… to indicate its intention” | What your own records show |
No badge decides it alone. A person who holds for weeks, trades often with borrowed money, and runs it like a business is in a different position from a person who buys an index fund once a month and holds for years. Most people sit somewhere in between, which is why the answer is “generally” and never “always”.

Are dividends taxable in Singapore?
For individuals, most are tax-free. IRAS lists as not taxable “Dividends paid to shareholders by a Singapore resident company under the one-tier corporate tax system (as the tax paid by a company is final), except co-operatives.”
Foreign dividends are also on the not-taxable list when they are “received in Singapore by resident individuals, except those received through a partnership in Singapore.” Tax withheld abroad on a foreign dividend is a separate matter, and depends on the other country’s rules.
How dividends and other corporate actions reach your account is covered in how SGX trading works.
What should a frequent trader actually do?
3 things, and none of them is a tax opinion.
- Keep records. A dated log of every trade, with the reason you took it, is good trading practice anyway. IRAS’s eighth badge looks at “the availability of documentation or other evidence” of intention, so your own records matter. A trading journal does both jobs.
- Read the IRAS pages yourself. Start with “Gains from sale of property, shares and financial instruments” and “What is taxable, what is not” on iras.gov.sg. They are short and plainly written.
- Ask before you assume. If you trade often, use margin, or trade through a company, check with IRAS or a tax adviser before you file. They can look at your facts, which no article can.
Tax is one of several things that sit around your trading and quietly shape the result. The others, from position size to drawdowns, are in the money and risk management guide, and the wider picture of stocks and CFDs is in the ultimate guide to stocks and CFDs trading.
Where does that leave you?
With a question of fact. For most people buying and selling shares in Singapore, IRAS treats the gains as personal investments, and they go untaxed. For a few, the pattern looks like a business, and IRAS may treat the profit as income. Which side you are on depends on how you trade, and only IRAS can rule on it.
If someone had to describe your trading from your records alone, would it read like investing or like a business?
