Frequently asked questions
Is Japan or United Kingdom better for tax?
It depends on your income, residency status and which special regime you qualify for. Compare the residency rules, rates and regimes side by side below, and use the interactive tool for your own income.
Which has the lower tax-residency threshold, Japan or United Kingdom?
Japan treats you as tax resident after its own residence test (no simple day count), and United Kingdom after 183 days. But ties like a home, family or economic centre can trigger residency on fewer days — never rely on a day count alone.
Does Japan or United Kingdom have a digital nomad visa?
Japan has a dedicated nomad/remote-work visa; United Kingdom has no dedicated digital-nomad visa. See the "Digital nomad visa" row below for the sourced detail.
