I’ve always calculated my business income for a full year to 30 April. On my tax return for 2010/11 I’ve recorded my business profits, income, and expenses for the year to 30 April 2010. But when I rang the Tax Office with a query the adviser told me that my accounts should always be drawn up to 5 April. Have I been doing it wrong for 20 years?
The adviser at the tax office is wrong. You can draw up your business accounts to any date you please. The year end of 30 April gives you a long delay between the end of your accounting year and the date on which you need to pay tax on the profits for that period.
