Key ISA, EIS and asset-backed deadlines for Tax Year End 2022/23

Tax year end is fast approaching and there are a number of key deadline dates you need to know to ensure your clients make the most of their annual allowances.

When is the deadline for using annual allowances?

The tax year ends on Wednesday 5th April 2023. However, many platforms and services require information to be submitted before this deadline in order to ensure that all investments can be completed before the end of the tax year.

This is true for ISA, EIS and asset-backed investments, with deadlines up to two weeks before allowances are refreshed and the new tax year begins.

In order to help your clients meet their deadlines, we have compiled a list of key dates for your diary to make sure they maximise their tax efficiency.
