Yes, but far less than most people assume. Listed options are qualified investments, so the tax rules permit them. What stops you is the account structure: a TFSA is a cash account, so it cannot use margin — which rules out every spread, every naked position, and every short sale.
What is left is buying calls, buying puts, covered calls, protective puts, and — depending on your broker — cash-secured puts.
People get this wrong in both directions. Some assume that because the tax rules permit something, their broker must allow it. Others assume that because their broker allows it, the CRA must be fine with it. Neither follows.
| Gate 1 — CRA | Is this a qualified investment? Listed options on shares of public companies are. This gate opens for everything a normal investor would trade. |
| Gate 2 — your broker | Do they permit it in that specific account? This is where most strategies actually die. |
Registered accounts are cash accounts. That is structural, not a policy your broker chose, and it does not change with your options approval level.
A spread contains a short leg. A short leg requires collateral. Collateral requires margin. Registered accounts cannot use margin. So the spread cannot exist there — even if you hold the highest approval level in your non-registered account.
| Strategy | Permitted? |
|---|---|
| Buy calls | Yes — fully paid at the outset |
| Buy puts | Yes |
| Covered calls | Yes — backed by shares you already own |
| Protective puts | Yes |
| Cash-secured puts | Broker dependent — see below |
| Any spread | No |
| Naked writing | No |
The CRA permits them. The cash is set aside, no margin is involved, and the structure is fine under the qualified investment rules.
Not every broker allows them anyway. Some Canadian brokers permit cash-secured puts in registered accounts at the appropriate approval level; others do not offer them.
There is one reliable way to find out, and it takes four minutes:
Phone your broker and ask: "Can I sell cash-secured puts in my registered account, and what option level do I need?"
They employ people whose job is to answer exactly that. It is faster than searching and far more reliable than a forum, where half the answers are out of date and a good proportion are about a different country.
Being permitted to place a trade and having the income stay tax-free are two different questions.
Under subsection 146.2(6) of the Income Tax Act, a TFSA that is carrying on a business is taxable on that business income. The TFSA trust itself is the taxable person — the CRA does not need to reassess you personally.
This is not theoretical. In Ahamed v The King, 2023 TCC 17, a self-directed TFSA grew from roughly $15,000 in contributions to over $617,000 through frequent trading in speculative stocks. The Tax Court held the TFSA was carrying on a business and the income was taxable. The Federal Court of Appeal affirmed in 2024 as Canadian Western Trust Company v The King, 2024 FCA 108.
The facts were extreme — the taxpayer was an investment adviser trading frequently in speculative securities. But the principle established is general, and it applies to options as much as to shares.
The CRA's published views have categorised option writing as a business activity, alongside foreign currency trading and excessive stock trading.
That is a direct statement about selling options, not an inference. It does not mean one covered call makes your account taxable — context matters and the multifactor test still applies. But a systematic covered call programme, run monthly across several holdings, sits closer to that line than most people running one realise.
The test comes from CRA Interpretation Bulletin IT-479R, Transactions in Securities, paragraph 11. Six factors, weighed together, with no single one deciding:
There is no answer, and the CRA has consistently refused to publish one. Reassessments have typically involved hundreds of trades a year with holding periods of days or less — but that describes past cases, not a safe harbour.
Anyone who gives you a number is inventing it. It does not come from the legislation, the bulletin, or the courts.
