Understanding Self Assessment Tax Returns: A Comprehensive Guide by The Infinity Group 

Navigating the intricacies of the UK tax system is essential for freelancers, self-employed individuals, and business partners. The Infinity Group is here to guide you through the Self Assessment ensuring compliance and peace of mind. 
 
What is a Self Assessment Tax Return? 
The Self Assessment Tax Return, a cornerstone of HMRC’s tax collection system, meticulously captures an individual’s earnings and income sources during the tax year. If you find yourself in any of the following situations, completing a Self Assessment Tax Return is mandatory: 
 
Self-employed as a sole trader with earnings surpassing £1,000 after tax relief. 
A partner in a business partnership. 
Total taxable income exceeding £100,000. 
Obligated to pay the High Income Child Benefit Charge. 
Additionally, untaxed income sources such as COVID-19 grants, rental income, tips, commissions, savings, investments, dividends, and foreign income may also warrant a tax return.
