Can I pay UK corporation tax from an overseas bank account?

HMRC publishes account details for payments from a non-UK bank account, including a specific IBAN and BIC for overseas transfers, separate from the standard UK sort code and account number. You will need the company's 17-character payment reference, which combines the UTR with the accounting period.

International transfers can take several working days to clear and count as paid only when HMRC's account is credited, so overseas owners should send funds well before the deadline rather than on the day.

Payment is due before filing: nine months and one day after the year end for payment, twelve months after the year end for the CT600 return itself. Missing the payment deadline triggers interest immediately even if the return is filed on time.

Companies with profit above £1.5 million pay in quarterly instalments instead, a threshold that rarely affects a newly formed overseas-owned company but is worth knowing about as profit grows.

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.

Rates, thresholds and deadlines here reflect the 2026/27 UK position and current Companies House and HMRC guidance. Check GOV.UK, or ask us, before relying on them for your own company.
