CT600 Tax Return Filing in Wallsend – Prepare and File Your Company Tax Return with HMRC

A CT600 is the Company Tax Return form used to report a company's Corporation Tax position to HMRC. It sets out details such as the accounting period covered, the company's income, allowable deductions, and the Corporation Tax calculation that follows from those figures. It is submitted to HMRC rather than to Companies House, and it is a different document from the company's statutory accounts. In most cases the figures in the CT600 are supported by a Corporation Tax computation that explains how taxable profit has been derived from the accounting profit.

Whether a company needs to file a Company Tax Return depends on its circumstances rather than on its size alone. HMRC can require a company to file a CT600, and a notice to deliver a return should be treated as an instruction to file. Some companies may not receive a notice in a particular period, and there are situations in which companies notify HMRC of their position instead of filing a full return. Because the requirement depends on the individual company's situation, it is worth checking your own position with HMRC or with an accountant rather than assuming a blanket rule applies.

Yes, they are separate filings with different purposes and different recipients. Statutory accounts are prepared under an accounting framework and filed at Companies House (and provided to members and, where relevant, HMRC). The CT600 is the Company Tax Return submitted to HMRC, and it reports the company's Corporation Tax position. The accounts often provide the starting point for the tax figures, but the return is not simply a copy of the accounts, and the filing obligations run independently of one another.

A company that qualifies as a micro-entity for accounting purposes may be able to prepare simpler statutory accounts, but that does not automatically remove any Corporation Tax filing obligation. If HMRC requires the company to deliver a Company Tax Return, it needs to file a CT600 reporting its position for the period. Equally, being a micro-entity does not mean Corporation Tax will necessarily be payable – that depends on the company's own income, deductions and taxable profit. Accounting size classification and Corporation Tax liability are two different questions.

No. The Corporation Tax computation is the working document that starts with the accounting profit and applies the relevant tax adjustments to arrive at the taxable profit, before the tax charge is calculated. The CT600 is the return form on which the resulting figures are reported to HMRC. A well-prepared computation makes the figures in the CT600 easier to follow and gives you a clear record of how the taxable profit was arrived at, which is useful if HMRC raises a query later.

Taxable profit generally begins with the profit shown in the accounts, but adjustments are then made to reflect how items are treated for tax purposes. Expenditure that is not allowable for tax may need to be added back; income or costs treated differently for tax may need to be adjusted; and capital items and other reliefs may be dealt with separately from the accounts. The result is the taxable profit used for the Corporation Tax calculation. Because the adjustments depend on the transactions involved, the computation should be prepared in line with the current rules that apply to your company.

No – filing and payment are separate obligations. Submitting the CT600 reports the company's position to HMRC, while paying Corporation Tax is a separate transaction that must be dealt with in its own right. Depending on the company's circumstances, Corporation Tax may be payable in instalments or by a single payment, and separate rules can apply to groups and larger companies. It is possible for a return to be filed on time while a payment obligation still exists, so both should be diarised and tracked carefully.

Yes. Companies commonly appoint an accountant or tax agent to prepare the CT600, prepare the supporting Corporation Tax computation and submit the return to HMRC on the company's behalf. The company remains responsible for the accuracy of what is filed and for making sure its records are complete, so the agent will normally need access to the accounting records, details of income and expenses, and information about any items that need special tax treatment. Can a company file its CT600 before its accounts are finalised? In practice the tax figures need to be based on complete and accurate accounting records, and the accounts themselves may need to be finalised before the computation can be prepared properly. Submitting a return on incomplete figures creates a risk of amendments being needed later, so it is generally better to resolve any open accounting questions first and then prepare the CT600 on a sound basis.
