Corporation tax, VAT and filing

Can I file UK company tax myself from overseas, or do I need an accountant?

Self-filing is legally possible from anywhere, but the combined complexity of CT600s, accounts and VAT makes an accountant the practical choice.

Short answer

There is no legal requirement to use an accountant; directors can file accounts, CT600 returns and VAT returns themselves using commercial software, from anywhere in the world. In practice, most overseas owners use an accountant because the combined workload, deadlines and specialist rules are harder to manage remotely without local knowledge.

What self-filing actually involves

Filing yourself means preparing statutory accounts to the correct format, computing corporation tax adjustments such as capital allowances and disallowable expenses, and submitting through commercial software since HMRC withdrew its own free CT600 filing tool for anything beyond the simplest company.

It is achievable for a very simple dormant or micro company, but becomes materially harder once there is payroll, VAT, foreign currency transactions or cross-border tax questions, all of which are common for non-resident-owned companies.

What an accountant adds beyond filing

A UK accountant handling non-resident clients monitors post at the registered office, tracks every deadline across Companies House, HMRC corporation tax and VAT, and applies rules such as disregarded income and treaty relief that self-filing software will not flag on its own.

For an overseas owner, the value is less about the filing itself and more about someone in the UK time zone catching problems, chasing missed post and translating UK-specific requirements into plain guidance before they become penalties.

What this costs with us

Our fixed monthly packages for a UK limited company start at £89 plus VAT and run to £169 and £289 plus VAT as bookkeeping, VAT, payroll and reporting are added. One-off filings are sold at fixed prices, and the Companies House fees we pay for you are charged at cost with no VAT added. Overseas owners are quoted on exactly the same published prices as UK-resident clients.
