Editing Individual savings account (section)

===Origins===
ISAs were introduced on 6 April 1999, replacing the earlier [[personal equity plan]]s (PEPs; very similar to a Stocks and Shares ISA) and [[tax-exempt special savings account]]s (TESSAs; very similar to a Cash ISA).  Other tax-advantaged savings that predate ISAs include many offered by [[National Savings and Investments]], a state-owned institution which has in the past offered a range of other tax-free accounts, in addition to its own ISAs.

Junior ISAs, introduced in 2011, replaced the [[Child trust fund|Child Trust Fund]].<ref>{{cite news| last=Blackmore| first=Nicole | title=Child trust fund savings can be moved to Junior Isas | newspaper=The Telegraph | date=23 December 2013| url=https://www.telegraph.co.uk/finance/personalfinance/savings/10534380/Child-trust-fund-savings-can-be-moved-to-Junior-Isas.html|quote = The schemes were replaced by Junior Isas in November 2011, which across the board offer better interest rates and a far wider selection of investments.}}</ref><ref>{{Cite web|title = Child Trust Fund - GOV.UK|url = https://www.gov.uk/child-trust-funds/overview|website = www.gov.uk|access-date = 2015-05-29}}</ref>

With a few exceptions, such as from an employee share ownership plan, all investor contributions must be in cash, not kind. Adult ISAs are available to UK residents aged over 16, provided that they have a [[National Insurance number]], but individuals between 16 and 18 are only permitted to use the adult cash component or can use a Junior ISA.

There are four broad types of adult ISA: cash, stocks and shares, innovative finance (including peer-to-peer lending) and lifetime.
