Withthe start of a new tax year just around the corner, it’s a good idea to startgetting your finances in order so that you don’t have a last-minute panic.

Last year, 12.5 million taxpayers submitted their tax returns to HMRC on time, with 778,068 submitting it on the deadline day. 32,958 submitted it between 23:00and 23:59 on the 31st January 2024!
Accordingto ‘Which?’, in a November 2022 survey, 31% of people who had filed a tax return before, saidthe thing they disliked most was worrying about making a mistake.

But it really doesn’t need to be this difficult, particularly if you keep yourfinances up-to-date throughout the year. Our team supports thousands of freelancers and small businessowners to manage their accountancy online, including their Self-Assessment Tax Return.

Here we explain more about what’s involved.

Who needs to complete a Self-Assessment?

You will normally need to complete a self-assessment if you areself-employed or a director / shareholder of a limited company. We can register you forself-assessment and prepare and submit your tax return on your behalf. Thisensures everything is done correctly and makes life easier for you. With adedicated accountant by your side, all you have to do is pay your tax bill usingthe verification HMRC sends when they confirm receipt of your tax return.

What to include in a tax return?

To complete your tax return, it is necessary to document allyour income sources over the year. If you are a company director and your onlyincome is a salary from your business, that’s what should be recorded on thetax return.

If you’ve received dividend payments or income from otherinvestments and shares, or an asset such as a rental property, this will needto be detailed too, as will any pension contributions, state benefits andcapital gains (such as a property you’ve inherited and disposed of) and lumpsums such as redundancy payments.
