Understanding Corporation Tax Return (CT600)

For Limited companies ("Limited" or "Ltd"), completing a Company Tax Return, formally known as a "Corporation Tax Return (CT600)", is mandatory, regardless of whether your business generates profits or incurs losses.

If your business is a limited company registered in the UK, you are obligated to pay corporation tax on your taxable profits. This requirement applies even if your business's primary operations are not based in the UK; if you maintain a UK branch or office, you're liable to pay corporation tax on profits derived from your UK activities.

To ascertain the amount of corporation tax owed, we undertake the preparation and submission of your company tax return on your behalf.

Corporation Tax Return Deadline Explained

The deadline for submitting your Company Tax Return is set at 12 months following the end of the corresponding 'accounting period.' However, this date varies for each business and hinges on your company's establishment date. If we did not assist with your company formation and you are uncertain about your accounting period, we can assist you in identifying the relevant dates.

Subsequently, there is a secondary deadline for settling your Corporation Tax. Typically, this falls 9 months and one day after the conclusion of the aforementioned accounting period.

It's crucial to note that there are penalties for missing your Company Tax Return deadline, with the severity contingent on the extent of the delay in filing.
