CT600 Tax Return Filing in Garforth – Preparing and Filing Your Company Tax Return with HMRC

A CT600 is the form used to file a Company Tax Return with HMRC. It reports a company's Corporation Tax position for an accounting period, including the taxable profit and the Corporation Tax calculated on it, along with other information HMRC requires such as the accounting period covered and details of the company. It is submitted to HMRC, not to Companies House, and it is a separate document from the company's statutory accounts, its Confirmation Statement and any VAT Returns. Most companies with Corporation Tax obligations file the CT600 online, either through HMRC's own service or through commercial software.

Yes, they are two distinct filings with two different recipients. Statutory accounts are prepared under the applicable accounting framework and filed with Companies House as part of the public record. The CT600 is a tax return filed with HMRC. Although both are usually based on the same underlying accounting records, they are not interchangeable: the accounts show the company's accounting profit or loss, while the CT600 reports the taxable profit after any Corporation Tax adjustments have been made. It is entirely normal for the two sets of figures to differ.

No. The Corporation Tax computation is the working paper that starts with the accounting profit shown in the accounts and adjusts it to arrive at the taxable profit — for example by adding back expenses that are not allowable for tax, removing income that is not taxable, or replacing accounting depreciation with capital allowances where relevant. The CT600 is the return form on which the results of that computation are reported to HMRC. In other words, the computation does the thinking and the CT600 does the telling. Preparing the computation properly is usually the part of CT600 Tax Return Filing that takes the most care and judgement.

Possibly, depending on the company's circumstances. Being a micro-entity affects how the statutory accounts may be prepared, but it does not by itself remove Corporation Tax filing obligations. A company that is within the charge to Corporation Tax, or that HMRC has asked to file a return, will normally need to submit a CT600. Equally, a micro-entity is not automatically liable to pay Corporation Tax — whether any tax is payable depends on the company's taxable profit and its own tax position. The safest approach is to review the company's circumstances and, where a return is required, prepare and file it on time.

We normally need the company's accounting records for the relevant accounting period, including sales and income, expenses with supporting documentation, bank statements, payroll information, and details of any assets purchased or sold. It also helps to know about anything unusual, such as loans to or from directors, dividends, interest received, or one-off costs, because these often trigger tax adjustments. If statutory accounts have already been prepared, we will use those as the starting point for the Corporation Tax computation. The clearer and more complete your records are, the more straightforward the CT600 Tax Return Filing process tends to be.

The accounting profit in your accounts is the starting point, but it is rarely the figure that is taxed. The Corporation Tax computation adjusts it to arrive at the taxable profit. Typical adjustments include adding back expenditure that is not allowable for tax purposes, removing income that is not taxable, and replacing accounting depreciation with capital allowances where the company is entitled to claim them. Other adjustments may apply depending on the company's activities and circumstances. Because these adjustments are specific to each company, the taxable profit can be higher or lower than the accounting profit — which is why a CT600 should never simply repeat the profit figure from the accounts without checking.

No, they are separate obligations. Filing the CT600 is about reporting the company's Corporation Tax position to HMRC, while paying Corporation Tax is about settling any liability that arises because of that position. A company can file a return showing no tax payable, and a company can owe tax that must be paid regardless of when the return is submitted. Keeping the filing and the payment in view separately helps avoid the common mistake of assuming that sending the return also settles the bill. If you are unsure what is due and when, we can help you work through it.

HMRC can charge penalties for filing a Company Tax Return late, and interest may also apply to any Corporation Tax that is paid late. The consequences generally depend on how late the return is, how many returns have been filed late previously, and whether any tax remains outstanding, so the position is not the same for every company. The practical point is that it is usually better to address a late or missing return promptly rather than let it sit — and if you are unsure whether a return is due, it is worth checking rather than assuming.
