Filing your self-assessment tax return in the UK can seem daunting, but it doesn’t have to be. Whether you’re self-employed, a freelancer, or have additional income, completing a self-assessment tax return is essential to ensure you’re paying the right amount of tax. This simple guide will help you navigate the process easily.
What is Self-Assessment?
Self-assessment is the system used by HM Revenue and Customs (HMRC) to collect income tax. If you’re an employee with only one source of income, your tax is usually deducted automatically through PAYE (Pay As You Earn). However, if you’re self-employed, or have additional income, you’ll need to complete a self-assessment tax return.
Who Needs to Complete a Self-Assessment Tax Return?
You may need to complete a self-assessment tax return if you:
Are self-employed or a freelancer.
Have income from property or investments.
Earn over £100,000 a year.
Receive income from savings or dividends.
Are a director of a company or a partner in a business.
Steps to Complete Your Self-Assessment Tax Return
Register with HMRC: If this is your first time filing a self-assessment, you’ll need to register with HMRC. You’ll receive your Unique Taxpayer Reference (UTR) and activation code for online services.
Gather Your Documents: Before you start filling out your tax return, make sure you have all necessary documents such as:
Income statements (P60, P45, payslips)
Self-employment income and expenses
Bank statements
Records of any other income (e.g., rental income, dividends)
Log into the HMRC Online Service: Once registered, log into your HMRC online account to begin your self-assessment tax return.
Fill Out the Tax Return: You’ll be asked to provide information about your income, expenses, and any other relevant details. Be accurate, as providing incorrect information could result in penalties.
Submit Your Return: Once everything is filled in, review your tax return carefully. After double-checking your details, you can submit your return electronically through HMRC’s online portal.
Pay Your Tax: After submitting, HMRC will calculate how much tax you owe. You must pay this by the deadline (usually January 31st for online returns) to avoid penalties.
Important Deadlines
Register by October 5th: If this is your first time filing a self-assessment tax return, register by October 5th of the tax year.
Tax Return Deadline: The deadline for online submissions is January 31st following the end of the tax year.
Pay Tax: The tax payment deadline is also January 31st.
Common Mistakes to Avoid
Missing the deadline: Always aim to submit your self-assessment tax return early to avoid late filing penalties.
Not keeping good records: Keep a record of your income and expenses throughout the year to make tax season easier.
Failing to claim deductions: Make sure you claim all allowable expenses if you're self-employed or have business income.
