Financial year end

When you incorporate a company, the company is given a default financial year end.

Usually this will be 12 months to the end of the month of incorporation.

For example, if you incorporated a business on 24 July 2023, then your company’s default year end would be 31 July 2024.

A small note on the side.  For accounting purposes this does not present any problems.  However, for corporation tax purposes, a period cannot be longer then 12 months long.

So, in the above case, two corporation tax returns will need to be prepared and submitted.

However, this default year end may not be practical or ideal for you.  So can you change your company’s financial year end?

Changing the financial year end

If you have not already changed your company’s year end, then the short answer here is yes.

You can change the year end to a date which is more practical for your business.

Common year ends include 31 December, or 31 March to align with the UK tax year.

For businesses which are seasonal, it is common to change the year end to the end of that seasonal period.

For example, a business that sells products or services related to Valentine’s day may choose a 28 February year end.

However, you can change your year end to any period that suits you and your business.
