Options in ISA, SIPP, and GIA

The general principle

The Individual Savings Account Regulations 1998 (SI 1998/1870, as amended) define what can be held in an ISA. They were made by the Treasury, not by HMRC — HMRC administers them. Regulation 7 sets out the qualifying investments for a stocks and shares component, and there is no derivatives category in it: the list runs to shares, qualifying securities, gilts and government securities, investment trusts, UCITS and non-UCITS retail scheme units, depositary interests, cash, insurance policies and long-term asset funds.

HMRC's guidance for ISA managers puts the exclusion in terms: "Qualifying shares do not include: nil paid rights (purchased in the market by the manager), warrants to subscribe for shares (but see shares and securities in investment trusts), futures or share options. These investments are not qualifying investments and may not be held in a stocks and shares ISA."

There is one genuine route to option-derived exposure inside an ISA, and it is not an exception to the above:

• Funds that use options internally. Covered call and option-income ETFs (e.g. UCITS versions of the US option-income funds) are qualifying ISA investments in their own right — not because their options are permitted, but because what you hold is units in a collective investment scheme, which is on the reg 7 list. The fund runs the option book; you never hold an option.

There is no equivalent exception for writing options yourself, on ISA-held shares or anything else. See option income alongside an ISA for what can actually be done.

Wrapper-by-wrapper rules

Stocks & Shares ISA

• Direct options trading: Not permitted — no strategy, no broker, no exception.
• Covered call writing on existing ISA shares: Not permitted. The written call is itself a share option, and share options are not qualifying investments.
• Option-based ETFs: Permitted (e.g. covered call ETFs), because you hold fund units rather than options.
• Tax: Tax-free growth + income inside the wrapper on whatever the wrapper is allowed to hold.

SIPP (Self-Invested Personal Pension)

• Direct options trading: Not an HMRC question — a scheme one. PTM121000 confirms "the tax rules for registered pension schemes do not impose any restrictions on the types of asset a pension scheme can invest in", and that scheme investments "include futures contracts and options contracts". Whether you can trade them depends on the provider or administrator, and almost none allow it.
• In practice: Hargreaves Lansdown and AJ Bell offer no options in any account, so neither permits them in a SIPP. Saxo's SIPP facilitates "non-leveraged products such as stocks, bonds and certain ETFs" and states that "access to leveraged products is not allowed" — options, futures, CFDs and FX are excluded. Interactive Brokers can support equity options in a SIPP sub-account, but IBKR does not accept direct SIPP applications: an approved third-party SIPP administrator opens the account and configures the trading permissions, and many administrators exclude options entirely. Confirm with the administrator, in writing, before transferring anything.
• Tax: Tax-free growth in wrapper. Withdrawals subject to pension rules (25% tax-free up to LSA cap).

GIA (General Investment Account / unwrapped)

• Direct options trading: All strategies permitted.
• Tax: CGT applies to gains above £3,000/year (2026/27): 18% basic / 24% higher.
• Bed-and-breakfasting 30-day rule applies — see the 30-day rule guide.

Junior ISA / Junior SIPP

• Options trading: Not permitted in a Junior ISA — the same qualifying-investment rules apply as to an adult ISA. In a Junior SIPP it is a provider restriction, and no mainstream provider allows it.
• Option-based ETFs: Permitted.

Option income alongside an ISA

Start from the honest position: there is no way to get option premium into an ISA tax-free. Not by writing calls against shares the ISA already holds, not through any broker, not on any underlying. The premium is consideration for granting a share option, the option is not a qualifying investment, and no ISA manager has discretion to accept one. If a page or a forum post tells you a named platform permits covered calls inside an ISA, check that platform's own investment range before you act on it.

What you can do is separate the two legs. Each route below has a real cost, and the cost is the point — none of them reproduces the tax-free premium that doesn't exist.

Shares in the ISA, option leg in a GIA

You keep the shares sheltered and write the calls in a General Investment Account. This works, but the two positions sit in different wrappers and the tax system treats them as unconnected:

• The call is naked as far as the broker is concerned. Your GIA cannot see shares held in an ISA — legally a different account, often a different provider — so the short call is not collateralised by them. Expect a margin requirement and the options approval level that goes with uncovered call writing, not the benign treatment a genuinely covered call gets.
• No netting between the wrappers. Premium and any gain or loss on the option are CGT events in the GIA, chargeable above the £3,000 annual exempt amount. Gains on the shares inside the ISA are outside CGT entirely. A loss on the option leg can only be set against other GIA gains — it can never be netted against the sheltered position it was written against.
• Assignment is the expensive part. If the call is exercised you must deliver shares. Selling the ISA shares to do it means taking them out of the wrapper: an in-specie withdrawal permanently loses that ISA shelter and cannot be put back except by using fresh annual subscription allowance. Buying the shares in the GIA instead means funding the purchase at market, plus 0.5% stamp duty reserve tax if they are UK shares.

A SIPP, where the administrator permits it

This is the only UK wrapper that can hold options and shelter the premium — but availability is the binding constraint, not the tax rules. As above, HMRC does not restrict the asset types a registered pension scheme may hold; the provider does. Hargreaves Lansdown and AJ Bell offer no options at all, and Saxo's SIPP excludes leveraged products. In practice that leaves Interactive Brokers via an approved third-party SIPP administrator, and only where that administrator has enabled options on the sub-account. Get it confirmed before you move a pension, and price in the administrator's fees, which are typically higher than a mainstream SIPP's.

Remember what the shelter costs: money in a SIPP is inaccessible until minimum pension age, and 75% of what you eventually take is taxed as income. Premium earned there is not tax-free — it is tax-deferred and then taxed at your marginal rate on the way out.

An option-income fund inside the ISA

A covered call or option-income ETF is ISA-eligible because you hold units in a collective investment scheme. The fund writes the options; you hold no derivative and the distributions are sheltered in the normal way. The trade-off is that you give up all control over strike, expiry and which positions get written, and you pay an ongoing charge for the manager to run it. It is a different product from writing your own calls, not a workaround for it.

Strategic implications

For income strategies (covered calls, cash-secured puts)

The wheel strategy (cash-secured put → assignment → covered call → assignment → cash-secured put) is most tax-efficient in a SIPP, if your administrator permits options at all — most do not. Second-best, and the realistic answer for nearly everyone: GIA with active CGT management. An ISA cannot run it in any form, because every leg of the wheel is an option.

For directional strategies (long calls, long puts)

GIA is the only practical option for most retail. Some SIPP brokers permit buying calls/puts as a directional hedge — confirm before opening.

For volatility strategies (iron condors, straddles)

GIA only. The complexity of multi-leg positions makes them impossible in standard ISA/SIPP setups.

For hedging an existing portfolio

If you have a £100k ISA, you cannot buy puts inside the ISA to hedge it. The practical answer is the first route below; the second is worth understanding mainly so you don't mistake it for a substitute.

• Hold cash outside the ISA in a GIA and buy puts there. The hedge behaves as intended, but it sits in a different wrapper: the premium and any payout are CGT events in the GIA, and a profitable hedge can generate a taxable gain in exactly the year your sheltered portfolio falls.
• An inverse FTSE 100 product inside the ISA is not an option-based hedge. These are short-and-leveraged ETPs that get their exposure through swaps or futures, not options — they are ISA-eligible only as listed securities. More importantly they reset daily, so their return compounds path-dependently and diverges from the inverse of the index over any period longer than a day. They are a short-term tactical instrument, not a standing hedge for a long-term portfolio, and they behave nothing like a put: no defined premium, no floor, and losses that are not capped at the amount you put in.

Tax-rate comparison by wrapper

For active options traders generating £20k+/year of gains, the wrapper choice can save £4,000+/year of tax. For occasional traders below £3k annual gains, the choice is administrative — same tax outcome.

Pitfalls to avoid

• Trying to "smuggle" options into a standard ISA. Voiding is not the automatic first consequence. The normal remedy is a repair: the manager strips the non-qualifying holding, and any income or gains arising from it, out of the wrapper, and HMRC's guidance confirms "invalid accounts can, in certain circumstances, continue as ISAs after being corrected". Full voiding — closing the account "with the loss of all tax exemptions" — applies only where the account cannot be repaired, such as a residence or age failure at the time of subscription. Either way you lose the shelter on the offending position and its gains, so the outcome is still bad; it just isn't the wholesale destruction of the ISA that the myth describes.
• Assuming a SIPP will allow options. Almost none do, and the restriction comes from the provider or administrator rather than HMRC. Confirm in writing before transferring a pension.
• Assuming a call written in a GIA is "covered" by ISA-held shares. It isn't — different account, no collateral link. You are writing an uncovered call and will be margined as such.
• Misreading the bed-and-breakfasting 30-day rule. It does apply to traded options: HMRC's CG55535 confirms "options of the same series are pooled in a Section 104 holding" and that the share identification rules therefore apply. But it does not block or disallow the loss. Section 106A TCGA 1992 is an identification rule: the disposal is matched against the reacquisition rather than the pool, so the loss is absorbed into the base cost of the new holding and deferred, not lost. Note also that the test is options of the same series — same type, same underlying, same expiry, same strike. A different strike or a different expiry is a different asset and is not caught. See the 30-day rule guide.

Sources and methodology

Rules above follow the Individual Savings Account Regulations 1998 (SI 1998/1870), reg 7 — made by the Treasury and administered by HMRC — together with HMRC's qualifying-investments guidance for ISA managers, PTM121000 on pension scheme investments, and published broker investment ranges checked in August 2026. Broker product ranges change — always confirm permitted instruments with the provider or SIPP administrator directly. For complex wrapper decisions, see the tax adviser editorial recommendation.
