Frequently asked questions

What is a CT600 tax return and why is it important?

A CT600 tax return is the form used by limited companies to report their profits and calculate Corporation Tax liability to HMRC. It is a legal requirement for every active company, and it must be submitted within twelve months of the end of your accounting period. Filing accurately and on time helps you avoid penalties and ensures you pay the correct amount of tax.

How can an ACCA or ICAEW accountant help with company tax returns?

ACCA and ICAEW accountants are highly trained professionals who specialise in tax compliance and planning. They can prepare your company tax returns, ensure all allowable expenses are claimed, and advise on tax-efficient strategies. Their expertise reduces the risk of errors and helps you meet HMRC deadlines without stress, giving you peace of mind.

What are the penalties for late filing of Corporation Tax returns?

If you file your Corporation Tax return late, HMRC will charge an automatic penalty of £100. If your return is late three times in a row, this increases to £500. Further penalties apply for longer delays, and interest accrues on unpaid tax. Professional accountants help you avoid these costs by ensuring timely and accurate submissions.

Can an accountant help with both Corporation Tax and Self Assessment?

Yes, many accountants are qualified to handle both Corporation Tax and Self Assessment. They can manage your company tax returns as well as your personal tax affairs if you are a director or shareholder. This integrated approach ensures that all your tax obligations are coordinated, minimising the risk of discrepancies and maximising tax efficiency.

What information do I need to provide for company corporation tax filing?

To prepare your company corporation tax filing, your accountant will need your financial records, including income, expenses, bank statements, and details of any assets. They will also require information about salaries, dividends, and any other payments. Providing organised records helps the accountant prepare an accurate CT600 return and identify potential tax savings.

How do I choose the right accountant in Carmarthen for my business?

Start by browsing local firms on AccountingFirms, where you can compare providers based on their qualifications, experience, and client reviews. Look for accountants who are ACCA, ICAEW, or AAT certified and who have experience with businesses similar to yours. It is also important to arrange an initial consultation to discuss your needs and ensure they are a good fit.
