Company Tax Return preparation and filing

An online accountant prepares your Corporation Tax calculation and Company Tax Return (CT600) from the company records. We also prepare the annual accounts needed for the standard trading package. You review the documents before we file with HMRC and Companies House.

From £199, bookkeeping included

£199 for a trading company with turnover up to £90,000 in the accounting period; £499 above £90,000. The price covers one company and one accounting period, subject to reviewing the records and agreeing the scope.

Any Corporation Tax owed is paid separately to HMRC. VAT, payroll, personal tax and specialist work are separate.
