FAQ
Questions we hear from UK clients
Short answers to start with. Your consultation covers the details for your situation.
See all questionsWhen is the Self Assessment deadline?
Online returns and any tax owed are due by 31 January after the end of the tax year. Paper returns are due earlier, by 31 October.
When do I have to register for VAT?
When your taxable turnover over the last 12 months goes above the VAT threshold (£90,000 at the time of writing), or you expect it to in the next 30 days. Registering voluntarily can also make sense — we will tell you if it does.
Can I run a UK limited company from outside the UK?
Yes. Directors and shareholders do not have to live in the UK. You will need a UK registered office address, and we handle the filings from there.
How much do your services cost?
Most work is priced as a fixed monthly fee or a fixed fee per filing, agreed in writing before we start. After a free consultation we send a proposal with the scope and price, so there are no surprises.
Can you work with me if I am in a different country?
Yes. Everything — document collection, review calls and sign-off — works remotely. Many of our clients live in one country and have filings in another.
