The situation
John and Sue had been living in Country Y for a number of years and were planning a move to Country X before ultimately returning to the UK. They wanted their financial and tax affairs fully reviewed and resolved before becoming UK resident again.
Their circumstances included a mixture of UK pension funds, ISAs, cash savings and other investments built up over many years. With several changes of residence behind them, one of the first priorities was to establish a clear timeline of where they had lived and been tax resident, and to identify any historic reporting or compliance matters that needed addressing before their return.
Where things became complicated
Residence history
Establishing a clear chronology of where they had lived and been tax resident, across several countries, before anything else could be planned.
Tax
Reviewing their UK and overseas tax position, including their pensions and investments while non-UK resident, and the consequences of moving from Country Y to Country X and then becoming UK resident again.
Pensions and investments
Reviewing their existing UK pensions and ISAs, and considering the right ownership and investment structure for their assets.
Sequencing
Rather than looking at pensions, investments or tax years in isolation, the work had to be coordinated across residence, tax reporting, pension planning, investment restructuring and the practical movement of capital between countries.
The Montfort approach
01 Establish the history
We built a clear chronology of their residence and tax history, and identified any historic reporting or compliance matters that needed addressing before their return.
02 Coordinate the tax position
We coordinated a review of their UK and overseas tax position, including their pensions and investments while non-UK resident and the effect of each move.
03 Review structure
We reviewed their existing UK pensions and ISAs, considered the right ownership and investment structure, and identified actions better taken before rather than after their return.
04 Sequence and implement
We created one coordinated implementation plan covering residence, tax reporting, pension planning, investment restructuring and the practical movement of capital between jurisdictions.
The turning point
The plan came before the move, not after it.
By the time John and Sue returned to the UK, historic issues had already been identified and dealt with, and the principal planning decisions had already been made. Sequencing the work, rather than tackling each pension, investment or tax year on its own, was what made that possible.
The outcome
By the time John and Sue returned to the UK, they had a clear understanding of their position, any historic issues had been identified and dealt with, and the principal planning decisions had been made in advance. This let them return with their financial affairs organised and a clear UK planning strategy already in place.
What this case shows
01 Look at the whole picture
Several changes of residence created tax and compliance questions that only showed up once the whole history was reviewed together.
02 Timing matters
Planning before the return to the UK meant issues were dealt with in advance, not discovered after.
03 Sequencing matters as much as the decisions themselves
A coordinated implementation plan, not isolated decisions about individual pensions or tax years, was what brought everything together.
