Can You Have More Than One Stocks and Shares ISA?
Navigate the nuances of Stocks and Shares ISA regulations to optimize your tax-efficient investment strategy and avoid common pitfalls.
An Individual Savings Account (ISA) is a tax-efficient investment vehicle. These accounts allow individuals to shelter their gains, income, and interest from UK taxes. The rules governing ISAs are established and overseen by HM Revenue & Customs (HMRC).
Stocks and Shares ISA Subscription Rules
Recent changes to ISA regulations allow individuals to subscribe to multiple Stocks and Shares ISAs within a single tax year, effective April 6, 2024. This represents a shift from previous rules, which generally limited new subscriptions to one Stocks and Shares ISA per tax year. While this offers flexibility, the total amount subscribed across all ISAs remains subject to an overarching annual allowance.
You can also hold numerous Stocks and Shares ISAs from previous tax years, with different providers, without impacting your current year’s subscription allowance. Individuals must track their total contributions across all providers to ensure compliance with the overall limit.
Understanding Your Overall ISA Allowance
The annual ISA allowance dictates the maximum total sum an individual can save or invest across all ISA types in a given tax year. For the 2024-25 and 2025-26 tax years, this allowance stands at £20,000. This limit applies comprehensively, encompassing contributions to Cash ISAs, Stocks and Shares ISAs, Innovative Finance ISAs, and Lifetime ISAs.
This overall allowance can be split across different ISA types. For instance, one could allocate a portion to a Cash ISA and the remainder to a Stocks and Shares ISA, as long as the combined total does not exceed £20,000. While multiple Stocks and Shares, Cash, and Innovative Finance ISAs can receive new subscriptions in a tax year, specific limits apply to certain types. A Lifetime ISA has its own annual contribution limit of £4,000, which counts towards the overall £20,000 allowance, and only one Lifetime ISA can be opened per tax year. Junior ISAs have a separate allowance of £9,000 for the same tax years, which does not count towards the adult ISA limit.
Transferring Existing ISAs
Transferring funds held within an existing ISA operates differently from making new subscriptions and does not impact the annual allowance. This process allows individuals to move their ISA savings between providers or even between different types of ISAs while maintaining their tax-free status. A proper ISA transfer must be initiated by the new ISA provider to ensure the tax wrapper is preserved.
Funds from an ISA opened in the current tax year can be transferred to another provider, but historically this required transferring the entire amount. Recent changes for the 2024-25 tax year now permit partial transfers of current year ISA funds. Funds held in ISAs from previous tax years can typically be transferred in full or in part, offering flexibility to consolidate or diversify holdings. These transfers are distinct from new contributions and provide a mechanism for managing ISA portfolios without penalty.
Consequences of Exceeding the Rules
Breaching ISA rules, such as exceeding the overall annual allowance or making impermissible subscriptions, can lead to corrective action by HMRC. If an individual contributes more than the £20,000 annual limit, or if they subscribe to a type of ISA where only one is permitted per year (like a Lifetime ISA), HMRC will identify the excess contributions. The responsibility for adhering to these limits lies with the individual, as each ISA provider only monitors contributions made to accounts they manage.
When a breach is identified, HMRC invalidates the portion of the ISA that exceeds the allowance or was opened improperly. This means that the ISA with the latest subscription, or the one that caused the breach, will be deemed invalid. Any gains, income, or interest generated within that invalid portion of the ISA then become liable for income tax, capital gains tax, or dividend tax, depending on the nature of the returns. The ISA provider will be instructed to remove the tax-exempt status from the affected funds, and the individual will be responsible for reporting these amounts to HMRC and settling any due tax.
