Tax Advice When Moving To The UK

Q: When do I need to file my UK tax return by?

Not all individuals are required to file UK tax returns and this will typically only be the case if you have untaxed income that you need to pay UK tax on or if you want to claim exemptions and reliefs. If you are required to file, you must register for self-assessment by 5 October following the end of the tax year and file your return by 31 January following the end of the tax year.

" Jacob is fast, structured, and deterministic. He responds quickly, gives clear and definitive answers where the law allows, and doesn't hide behind vague replies. He knew the expat and non-resident space cold — no need to "look into it later." The written advisory memo was clear and actionable, and the tax return was prepared and filed efficiently with minimal back-and-forth. If you're a non-resident, digital nomad, or expat dealing with a complex tax situation, I'd strongly recommend Jacob. He's exactly the kind of advisor you want in your corner. "
