We prepare the necessary Statement of Profit & Loss and Statement of Financial Position, and submit them directly to Companies House once they have been approved by the company.

You are also required to file a Corporation Tax Return annually with HMRC. We’ll take care of everything that HMRC requires and inform you of the corporation tax payment due well in advance. We will calculate your Corporation Tax liability, complete the CT600 tax return, and submit it to HMRC once it has been approved by the company.

If you have our Accounts Package your Annual Accounts are already included in your package and you don't need to pay any additional fees for them.

The price of accounts may be more or less than the base price, and will be outlined in your Proposal. For example, simple accounts and tax affairs may afford a discount; more complex accounts with lots of transactions or complications may incur a higher price.
