What is an accounting year?

Definition of an accounting year

An accounting year is the year covered by your business's accounts. Every business must prepare accounts for a year at a time.

Accounting years for different business types

Sole traders

If you're a sole trader, the easiest accounting year end for you is 5th April, to match the tax year end, or 31st March, which HMRC treat as matching the tax year end.

Limited companies

If you run your business through a limited company, Companies House will set your accounting year end as a year after the end of the month in which you created ('incorporated') the company.

You may wish to change your company's accounting year end to match the calendar year (31st December) or the financial year (31st March).

Frequently Asked Questions

Why is it easier to have my accounts match the tax or financial year end?

Tax reliefs such as capital allowances often change at the tax or financial year end, so you could save time on calculations by choosing the tax or financial year end for your accounts.
