Managing your Self Assessment tax in the UK can often resemble piecing together a complex puzzle, particularly when you have multiple streams of income to consider. However, there’s no need to feel overwhelmed! This comprehensive guide will empower you to confidently navigate the Self Assessment process, ensuring that you accurately report all of your income, whether it comes from employment, investments, or other sources.
Understanding the basics of Self Assessment Tax
What is Self Assessment Tax return?
Self Assessment is the way HMRC collects income tax from individuals. It places the responsibility squarely on you to report your income, expenses, and other crucial details.
Who needs to complete a Self Assessment?
The requirement to complete a Self Assessment tax return applies to various individuals. Primarily, if you are self-employed, a partner in a business partnership, or earning income from other sources—such as renting out properties or generating investment income—you will typically be obligated to file a Self Assessment. Additionally, those with income exceeding certain thresholds or complicated financial circumstances, such as company directors or those with income from abroad, will also need to complete a Self Assessment.

Identifying your income sources
To accurately complete your Self Assessment, it’s crucial to identify and report all your income sources. Here’s an in-depth look at typical income streams:
Employment income
Employers typically deduct Income Tax and National Insurance from employees’ paychecks using the PAYE system. However, even though these deductions are made before you receive your pay, you are still required to report your total employment income on your Self Assessment tax return if you are receiving other income. Include any bonuses, overtime, or taxable benefits you receive from your employer.
Self-employment income
Keeping meticulous records of your income and allowable expenses is crucial if you operate your own business. These records provide a clear picture of your profits and will be necessary for calculating your taxable income accurately. Remember, allowable expenses include office supplies, travel, and business-related utilities, among others.
Rental income
For those renting out residential or commercial properties, it’s critical to declare all rental income earned during the tax year. Besides reporting the total revenue, be aware that you can claim certain expenses against this income, such as repairs, property management fees, and mortgage interest, which can reduce your overall taxable income.
Investment income
Investment income encompasses a range of earnings, including interest earned on savings accounts, dividends from shares, and any capital gains realised from selling assets. Each form of income must be assessed and reported accordingly. It’s important to highlight that there are particular allowances, like the Dividend Allowance and the Personal Savings Allowance, for which you might qualify, possibly lowering your tax burden.
Foreign income or gains
If you have earned income or made gains abroad while being a UK resident, including this information in your Self Assessment tax return is imperative. The UK taxes its residents on their worldwide income, so all foreign earnings must be accurately reported. This includes income from overseas employment, foreign property rentals, and dividends from international investments. Ensure you are aware of any double taxation agreements that may apply, which could help mitigate your tax liability on foreign earnings.
Side hustles
If you are regularly selling items through an online marketplace or running a regular service where you are earning income, those all need to be included in your Self Assessment tax return. Best to be upfront, HMRC gets lots of information you may not be aware of through the digital sales reporting legislation, which came into effect on 1 January 2024; for example, eBay will pass on data to HMRC automatically of anyone selling 30 or more items through them a year or if the person has received total earnings over the equivalent of £1,740.
