Filing a self-assessment tax return in the UK can be a daunting task, even for the most financially savvy individuals. The intricate nature of tax regulations and the fear of making mistakes often lead to errors that can have serious consequences. In this article, we will delve into the top five common errors people make in their self-assessment tax returns and provide guidance on how to avoid them.
One of the most prevalent errors in self-assessment tax returns is misreporting income. This can occur when taxpayers fail to accurately declare all sources of income, including freelance earnings, rental income, dividends, and interest. HM Revenue & Customs (HMRC) has access to various databases, making it easy for them to cross-reference the information provided in your tax return with the income reported by third parties. Failure to report all your income can lead to penalties and potential legal consequences.
How to avoid it: Maintain detailed records of all your income sources throughout the tax year. Use the information provided on forms like P60 and P11D as a reference to ensure accurate reporting.

Incorrect Expense Claims
Claiming excessive or inappropriate expenses is another common mistake. While it’s essential to claim legitimate business expenses to reduce your tax liability, some taxpayers exaggerate expenses or claim personal costs as business expenses. This can trigger HMRC‘s scrutiny and result in penalties.
How to avoid it: Familiarize yourself with the HMRC guidelines on deductible expenses. Keep organized records and receipts for all claimed expenses, ensuring they are directly related to your business activities.
Mathematical errors in calculations can lead to discrepancies in your tax return. These errors can be in the form of miscalculating income, deductions, or tax credits. Even a simple mistake can result in an incorrect tax liability, which might raise red flags during HMRC’s review.
How to avoid it: Use tax software or work with a qualified accountant to ensure accurate calculations. Double-check all your entries and calculations before submitting your tax return.
Missing Deadline or Incomplete Filing
Missing the self-assessment tax return deadline (31st January each year) is more common than you might think. Submitting your return late incurs an automatic penalty, which increases the longer you delay. Additionally, incomplete filings—leaving out important sections or failing to provide necessary documents—can lead to unnecessary complications.
How to avoid it: Mark the tax return deadline on your calendar and set reminders well in advance. Begin the process early to avoid a last-minute rush. If you’re having trouble completing your return, consider seeking professional help.
Inaccurate Classifications and Categories
Assigning the wrong classifications or categories to your income and expenses can confuse HMRC and potentially trigger audits. This includes misclassifying different types of income, such as mixing capital gains with regular income, or using incorrect tax codes.
How to avoid it: Educate yourself on the proper classification of various income sources and expenses. Use the guidance provided by HMRC or consult a tax professional if you’re unsure.
Filing a self-assessment tax return is a responsibility that requires attention to detail and a solid understanding of tax regulations. By avoiding these common errors—such as misreporting income, incorrect expense claims, calculation mistakes, missing deadlines, and inaccurate classifications—you can significantly reduce the risk of penalties, audits, and unnecessary stress.
While it’s possible to prepare your self-assessment tax return independently, seeking guidance from a qualified accountant or using reputable tax software can provide an added layer of confidence in the accuracy of your return. Remember, a well-prepared and error-free tax return not only ensures compliance with HMRC but also helps you make the most of available deductions and credits, ultimately minimizing your tax liability.
