Options for 401k

Hello, I was wondering what others may have done with their 401k when moving to the UK.
I'm with Vanguard thru my employer, and I also have a pension in the UK from years ago when I worked in the UK. Now planning on going back again (on spouse visa). I am 17 years from full retirement age.

I rolled my employer 401k, managed by Schwab, into a Vanguard Rollover IRA before I moved back to the UK.  There is no tax consequence for a rollover like this, directly into another brokerage.

Vanguard allows customers to manage their IRA's once they move overseas provided that the IRA is opened before they move.

thank you for your response.

Because HMRC might treat a rollover as UK taxable (don't worry why too much, but HMRC have a peculiar view); ideally a rollover would be made in the UK tax year before returning to the UK.

What is the peculiar HMRC view? I was always under the impression they took the treaty view which was that rollovers were not UK taxable.

HMRC now say that the US Treasury Technical Explanation is not HMRCs view, so is not binding on them.  Some (limited) published guidance can be seen on page 3 here: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/455369/Minutes_8_July_2015.pdf
