What is a Company Tax Return?

A Company Tax Return  is the return that must be submitted to HMRC by Ltd Companies after the end of their financial year.

A form called a CT600 is the main part of the Company Tax Return.

A Ltd Company’s financial year can run to the last day of any month of the year, usually initially dictated by the month that the company was incorporated.

The deadline for your Company Tax Return is 12 months after the end of the accounting period it covers. You’ll have to pay a penalty if you miss the deadline.

Interestingly there is a separate deadline to pay your Corporation Tax bill which is usually 9 months and one day after the end of the accounting period. We recommend that all our clients file everything well before either deadline so that they know exactly what they have to pay and when.

You can check when your company year end is on the Companies House website.


What is the purpose of a Company Tax Return?

Your Company Tax Return tells HMRC how much taxable profit your company has made and subsequently the amount of tax you should pay.

Taxable profit and Operating profit can be quite different depending on the allowances and accounting treatments used – so it’s important that you either know exactly what you’re doing, or that you get an expert like Mazuma to do it for you.

Who has to file a Company Tax Return?

Ltd Companies, regardless of their size or how much money they have made, will need to file a Corporation Tax Return with HMRC. You’ll be sent a ‘Notice to Deliver a Company Tax Return’ by HMRC which will tell you the date by which you have to file. It’s important that you check that this date is correct and inform HMRC if you think you should be filing to a different date.

There are some Ltd Companies that may not need to file a Company Tax Return if HMRC regards them as ‘dormant for Corporation Tax’

How do I file a Company Tax Return?

Ltd Companies can file their Corproation Tax Return using the HMRC website or by using a piece of third party software. But be warned! You’ll need to submit your Company Accounts to HMRC at the same time. And not just as a pdf, but in a special format called iXbrl. Specialist software can produce your accounts in this format, but we don’t advise that business owners attempt this themselves unless they have experience of producing accounts.

It is always better to get a professional to produce and file your Accounts and Company Tax Return on your behalf so that you can rest assured that everything is correct and you won;t incur any fines or penalties from HMRC for late or incorrect filing.
