MAR² Ledger

Corporation Tax filing

Corporation Tax for UK limited companies. Keep each company’s accounting periods, prepare the CT600 with a live tax calculation (main rate, small profits rate and marginal relief), attach iXBRL accounts and computations, and file with HMRC. Ledger follows each return to HMRC’s outcome and tracks what is owed and paid. MAR² Ledger is independent software and is not part of, or endorsed by, HMRC.
