If you’re self-employed, a company director, or have other forms of income not taxed at source, you may need to file a self-assessment tax return with HM Revenue and Customs (HMRC) in the UK. Filing your tax return can seem like a daunting task, but with the right information and guidance, you can complete the process with ease.
What is Self-Assessment Tax?
Self-assessment tax is a system in the UK that requires taxpayers to declare their income and pay any tax due directly to HMRC. This applies to individuals who have income not taxed at source, such as self-employment income, rental income, or investment income. The self-assessment tax also applies to company directors, high earners, and those with complex tax affairs.
The self-assessment tax process involves completing a tax return form, declaring your income and expenses, and paying any tax due. You’ll need to file your tax return by 31 January each year for the previous tax year, which runs from 6 April to 5 April the following year.
How to Register for Self-Assessment Tax
If you’re self-employed or have other forms of income not taxed at source, you’ll need to register for self-assessment tax with HMRC. You can do this online or by filling out a form and sending it by post.
When you register, you’ll receive a Unique Taxpayer Reference (UTR) number, which you’ll need to complete your tax return. You’ll also receive a letter from HMRC outlining the next steps you need to take.
Completing Your Self-Assessment Tax Return
Once you’ve registered for self-assessment tax, you’ll need to complete your tax return each year by 31 January. You can do this online or by using paper forms, which must be submitted by 31 October.
Your tax return will ask for information about your income and expenses, including any employment income, self-employment income, rental income, or investment income. You’ll also need to declare any deductions or allowances you’re entitled to, such as business expenses, charitable donations, or pension contributions.
If you’re completing your tax return online, the system will calculate your tax liability for you, based on the information you provide. If you’re using paper forms, you’ll need to calculate your tax liability manually.
Paying Your Self-Assessment Tax
Once you’ve completed your tax return, HMRC will send you a statement of your tax liability. You’ll need to pay any tax due by 31 January, along with any payments on account due for the following tax year.
Payments on account are advance payments towards your next year’s tax bill. They’re calculated as half of your previous year’s tax bill, and are due on 31 January and 31 July each year.
You can pay your self-assessment tax online, by bank transfer, or by cheque. HMRC will provide you with the details you need to make a payment.
Self-assessment tax can seem complicated, but it doesn’t have to be. By registering for self-assessment tax, completing your tax return on time, and paying any tax due promptly, you can stay on top of your tax affairs and avoid penalties.
If you’re struggling to complete your tax return or have any questions about self-assessment tax, you can contact HMRC for help and guidance. They have a dedicated self-assessment helpline, as well as online resources and guides to help you through the process.
