Why UK obligations still apply
UK tax residence for a company is based on the place of incorporation, not the location of its trade, so a company doing all its business overseas is still taxed in the UK on its worldwide profit unless it is also treated as resident elsewhere and a tax treaty allocates residence away from the UK.
Where profit is genuinely earned and taxed overseas, double tax relief or a treaty exemption can prevent double taxation, but this needs active management rather than assuming trading abroad removes UK tax entirely.
