Corporation Tax accountant for UK limited companies

A Corporation Tax accountant prepares your company accounts, calculates the Corporation Tax due, completes and files the CT600 with HMRC and advises on legitimate reliefs and planning opportunities. At NDCA, one named accountant handles this alongside your annual accounts.

Our fees start from £95 plus VAT a month for limited companies, with no setup fee. Self Assessment starts from £245 plus VAT as a one-off fee. You receive a fixed quote at the end of your free 30-minute call, based on your turnover, transactions, VAT, payroll and number of directors. Any records alignment or bookkeeping catch-up is quoted separately in writing before work starts.

Corporation Tax is generally due nine months and one day after the end of your accounting period. The CT600 return itself has a later deadline, twelve months after the period ends.

A CT600 is the Company Tax Return a limited company files with HMRC. It reports the company’s income, calculates the Corporation Tax due and is based on the Corporation Tax computation drawn from the statutory accounts. The CT600, the accounts and the computation are related but are three separate documents.

There is no single trick. Legitimate ways to manage a Corporation Tax bill include claiming the capital allowances and reliefs your company is entitled to, timing certain expenditure correctly and making use of loss relief where it applies. We review each client’s position individually rather than applying the same approach to every company.

A limited company can generally claim expenses that are wholly and exclusively for business purposes, such as staff costs, business premises, equipment, professional fees and business travel. Some costs, such as client entertainment, are not allowable. We review your expenses as part of preparing your accounts.

Capital allowances let a company deduct the cost of qualifying assets, such as equipment, machinery and some fixtures, from its taxable profit rather than treating them as a standard expense. The Annual Investment Allowance covers most qualifying purchases up to the current annual limit. We check what your company can claim as part of preparing your Corporation Tax computation.

A company that makes a loss does not pay Corporation Tax for that period, and the loss can usually be carried back, carried forward or in some cases set against other income, depending on the circumstances. A Company Tax Return is still normally required even where no tax is due.

Many directors also need to file a personal Self Assessment return, particularly where they take dividends or have other income outside PAYE. Corporation Tax and Self Assessment are separate filings that need to work together. NDCA can look after both, so the two returns line up.

Yes, at any point in the year. We handle the handover with your previous accountant and keep you updated until it is complete.

No, a director can file a Corporation Tax return without an accountant. In practice, most limited company owners use one to make sure the computation is correct, the right reliefs are claimed and the return is filed on time. NDCA prepares and files the return as part of a fixed monthly fee.
