Every company is bound by law to pay Corporation tax. They have to fill in the Corporation Tax Return Form to the Inland Revenue along with all the supporting documents to validate the tax preparation. CT600 named form filled by smaller companies. While maintaining their daily accounts it is imperative for the company to maintain the records in such an order that a precise Tax Return for the company can be filled.
As I heard about one of mine financial adviser friend about Professional accounting firms, which offer services to prepare your tax preparation and ensure that you "legally" pay significantly lesser amounts as corporation tax.
Factors like over-charging, under-charging or you may end up filling the form inappropriately which can easily handle by them. Their experience, knowledge is the best in the industry, can save you a lot of precious time and money.
It is legally compulsory for companies to file in their Tax Return within twelve months after the end of the accounting period.
Before your company heavily fined and penalized, complete carefully its tax preparation and subsequently pay the corporation tax.
Money and time you would be able to save would surpass the fees you pay.
