Editing Individual savings account (section)

==Subscription limits==
There are restrictions on investing in ISAs in each [[tax year]] (6 April to the following 5 April) which affect the type of ISA that may be opened and the cumulative amount of investment during the course of that year. The key restrictions are:

*The limits are per ISA, not per account, so you can have many accounts with current year money at one manager, all within the same overall ISA. This is sometimes called a "split ISA".
*No more than the annual amount limit can be paid in. Formerly, the amount of subscription in cash used to be restricted in an adult ISA. Any amount not used for cash can be used in other types of ISA.
*Newly subscribed (paid in) money in the current tax year can only be held in one Individual Savings Account of each type. For example, current year cash ISA subscription money can be held in a help to buy account, instant access accounts, fixed rate accounts, variable rate accounts and deposit accounts with the same cash ISA manager in the same overall ISA even though this is five or more accounts. None could be held in any accounts within another cash ISA elsewhere. The introduction of the help to buy cash ISA made this flexibility within one ISA more significant because it cannot use the full cash limit.{{clarify|date=March 2025}}
*Provided the annual contribution limits are not exceeded significantly HMRC can be expected to forgive one transgression using too many ISA managers/accounts and merely post a letter reminding about the rules after the annual returns from ISA providers reveal the problem.<ref name=HMRCBulletin14>{{cite web|url=http://www.hmrc.gov.uk/isa/bulletin14.htm|title=ISA Bulletin 14: HMRC compliance|publisher=[[HM Revenue and Customs]]|access-date=2 April 2013|quote=those who over-subscribe for one year, but not significantly in excess of the annual subscription limits, receive a letter drawing their attention to the ISA rules and advising them no action will be taken unless they over-subscribe in a later tax year}}</ref> This should not be relied upon, as it is at HMRC's discretion.

These restrictions only apply to money paid in during the current tax year. For adult ISAs an unlimited number of ISA managers' accounts can hold money from past years and it can be freely moved between managers using ISA transfer requests.
