Some financial decisions carry tax consequences that only become clear after the fact. We work with clients who want to understand their position before they act, not after.

We advise on IR35 status and contractor arrangements, incorporation decisions for sole traders and partnerships, capital gains tax on cryptocurrency disposals, and UK tax residency including permanently severing UK tax ties for clients relocating abroad.

If your situation does not fit a standard template, that is exactly the kind of work we do.
