    What is a Self-Assessment tax return?

    A Self-Assessment tax return is a form you fill out to declare your income and capital gains to HMRC. It determines how much tax you owe or how much will be refunded for the tax year.

    Who needs to file a Self-Assessment tax return?

    Generally, if you are a sole trader or self-employed and make a profit, then you will be expected to pay tax on your income, much like how employees pay tax through their salary.

    Since employees pay tax directly through their salary, they don’t have to worry about working out the numbers. Working for yourself, on the other hand, means filing a yearly tax return to ensure HMRC is notified and you pay the correct amount of tax.

    Unsure whether you need to file a Self-Assessment return? There are various reasons why you might need to, including if:

    • you are a self-employed sole trader with annual profits of over £1,000;
    • you are a partner in a business partnership;
    • your total taxable income is over £100,000;
    • you receive £2,500 or more in untaxed income, such as renting out property;
    • you receive £10,000 or more in savings or investments.

    If any of these sound like you, then get in touch, and we can help you with your tax liabilities. HMRC also has a helpful online tool to help determine whether you need to file a Self-Assessment return.

    When should you do a Self-Assessment tax return?

    When it comes to your finances, timing is everything. For online Self-Assessment returns, the deadline is 31 January, following the end of the tax year.

    To reduce the risk of a hefty fine or financial stress, you should submit your Self-Assessment tax return long before this deadline.

    At Guildford Accounting, we are committed to ensuring you don’t pay the consequences of a late tax return. With a mix of accounting expertise, experience and the latest cloud accounting software, we implement a robust tax strategy that means no late payments.

    What is the fine for a late Self-Assessment tax return?

    While we make every effort to ensure you don’t experience the consequences of a late tax return, it’s important to be aware of the impact. Missing the January deadline results in an automatic fine of £100. You will also start accruing interest on late payments from 1 February.

    We understand that managing your own financial affairs can be challenging – especially while running a business. To help take some of the weight off your shoulders, we are helping you with our personal tax returns service.

    If you are looking for more information to help you understand how Self-Assessment tax returns work, please look at some of our frequently asked questions below.

    How many years of Self-Assessment tax returns should I keep?

    Generally, you’ll be required to keep your Self-Assessment records for at least 5 years after the submission deadline (31 January) in the relevant tax year. This ensures you have the relevant documents to refer back to if needed.

    What is the difference between Self-Assessment and tax return?

    Self-Assessment refers to the system used by HMRC to collect tax from self-employed individuals. Whereas a tax return is the actual form that is submitted to detail the amount of tax owed.

    How often should you do a Self-Assessment tax return?

    If you work for yourself, then you are expected to file annual Self-Assessment tax returns to HMRC and pay the relevant amount of tax due. The deadline is 31 January for online returns and 31 October for paper returns.

    How long does it take for HMRC to process a Self-Assessment tax return?

    The amount of time it takes HMRC to process a Self-Assessment return varies depending on whether you submitted it online or via post. Online returns tend to have a faster turnaround, while paper returns can take much longer.
