About
Straight answers, from someone who does this every day
Emma advises expats, digital nomads and globally mobile professionals on UK tax — residency, exit and entry planning, returns and voluntary disclosures. The work is deliberately narrow: no bookkeeping, no payroll, no company accounts. Just UK tax for people whose lives cross borders.
Most clients arrive with the same problem. They have left the UK, or arrived in it, and cannot get a straight answer about what HMRC can still tax. The rules are knowable, but they are scattered across guidance written for advisors rather than the people affected by them.
Everything published here is written to close that gap: the actual rule, in plain English, with the traps named. Emma is a member of the Association of Taxation Technicians, and Global Tax Consulting is registered with HMRC as an agent.
With the right advice, international tax doesn’t have to be complicated. In fact, some of the biggest opportunities to optimise your tax position arise while you are a global citizen.
