Putting Shares into an ISA Wrapper – is it worth it?

In a recent Q&A with The Scotsman, we respond to a reader who grew a £15,000 share portfolio to £56,000 using a classic buy-and-hold strategy. While the reader now faces tax on dividends, they asked if these shares could be moved into an ISA to protect future income and growth from tax.

Andrew explained that although holding shares within an ISA is tax-efficient, moving existing shares isn’t always straightforward. They must be sold first, which can trigger Capital Gains Tax (CGT) if the gains exceed the annual exemption. A phased approach can reduce the CGT bill, but fully transferring a large portfolio can take years – or a bigger tax hit upfront if done faster.

He highlights that the decision could be seen as a balance between paying CGT now and enjoying future tax-free income. Speaking with a qualified financial planner can help find the right strategy.
