Playbook №1 · for movers with equity and US accounts

The US→UK Move Playbook

Built for people moving from the US to the UK who have RSUs, a 401(k) or Roth, a regular investment account, and a move date (or a firm plan to have one). It is the same guide for everyone in that spot, and it feels personal because the spot is specific.

Every section is dated, so you always know which year’s rules it was written against, and it shows the sources behind what it says. When a rule changes, we update the playbook and email you what changed and why.

Start here: your move, mapped

The playbook opens with your move on a single timeline, set up with a typical mover's year. Drag the move date and each event switches rulebooks. This is the moment it clicks, before any of the detail arrives.

The thirteen sections that follow work through what the timeline surfaces, from residence and the FIG window to your investments, the accounts to open and close, the state you're leaving, your retirement and equity, the paperwork, and family who aren't US taxpayers, ending with a first-90-days calendar built around your own move date and an honest chapter on when a professional is worth it, and how to arrive prepared.

The full section, and everything below it, opens after you buy.

What’s inside

Nine interactive tools, powered by the same tested rules as the free tools on this site, just without the trimming.

  • Your move on a timelineDrag your move date and watch each event switch between the US and UK rulebooks.
  • Residence day counterThe full day-count tool: days in the UK, your ties, and both arriving and leaving. It shows how much room you have and which test decided it.
  • Split-year checkerFlags which split-year cases your situation is likely to meet. When the honest answer is that it depends on your details, it says so instead of guessing.
  • Fund and PFIC checkerSorts the kinds of holdings you own and lays the options out side by side, each with the source behind it.
  • Before-and-after timing examplesTwo worked examples on the timeline, using clearly labelled sample numbers, never your own.
  • State exit checklistA checklist tailored to your state (New York, California, or Massachusetts) that saves as you tick things off.
  • Equity split exampleOne RSU grant drawn across your move date, with the split shown as a shaded band. A worked sample, not your numbers.
  • Paperwork checklistYour reporting to-dos grouped by type, each with the rule behind it, saved to your account.
  • First-90-days calendarEverything above pulled into one dated checklist that re-dates itself around your move.
