Self-Assessment Tax Returns: Common Pitfalls and How to Avoid Them

Published: 20 April 2024

The self-assessment tax return is an annual ritual for many in the UK, including the self-employed, certain business owners, and individuals with various forms of untaxed income. While it’s a fundamental aspect of tax compliance, it’s fraught with potential pitfalls that can lead to stress, penalties, and sometimes, overpayment. At DD Accounting, we’re committed to guiding you through the self-assessment process with minimal fuss. Here’s a look at common pitfalls and our expert advice on avoiding them.

1. Missing the Deadline

The Pitfall: One of the most common and easily avoidable mistakes is missing the self-assessment deadline. For online returns, the deadline is January 31st following the end of the tax year. Late submissions incur an immediate £100 penalty, which increases over time.

How to Avoid: Start preparing your tax return well in advance. Consider setting reminders leading up to the deadline or, better yet, aim to submit your tax return months ahead to avoid last-minute pressures.

2. Inaccurate Records

The Pitfall: Failing to keep detailed and accurate records can make filling out your tax return a nightmare. Inaccuracies can lead to penalties or result in you paying more tax than necessary.

How to Avoid: Maintain diligent financial records throughout the year. Digital accounting software can streamline this process, making it easier to gather the necessary information when tax season arrives.

3. Overlooking Allowable Expenses

The Pitfall: Many individuals fail to claim for all the expenses they’re entitled to, effectively paying more tax than they need to. Commonly overlooked expenses include home office costs, business travel, and professional subscriptions.

How to Avoid: Familiarise yourself with HMRC’s guidelines on allowable expenses. If in doubt, consult with an accountant who can help ensure you’re claiming all your entitled deductions.

4. Incorrectly Reporting Income

The Pitfall: Incorrectly reporting income, whether by underreporting earnings or failing to declare all income sources, can lead to investigations by HMRC and potential penalties.

How to Avoid: Ensure all income sources, including rental income, dividends, and any overseas income, are accurately reported. Using a comprehensive accounting solution or consulting with a professional can help mitigate errors.

5. Not Saving for Your Tax Bill

The Pitfall: It’s not uncommon for individuals and small business owners to be caught off guard by their tax bill due to inadequate financial planning.

How to Avoid: Regularly set aside a portion of your income in preparation for your tax bill. A good rule of thumb is to save around 20-30% of your income, depending on your expected tax bracket, in a separate savings account.

6. Handling the Process Alone

The Pitfall: Attempting to navigate the self-assessment process without professional help can be daunting and may lead to costly mistakes.

How to Avoid: While it’s entirely possible to manage your self-assessment tax return on your own, leveraging the expertise of an accounting firm like DD Accounting can provide peace of mind and potentially save you money by identifying additional savings or avoiding penalties.

The self-assessment tax return doesn’t have to be a source of anxiety. By understanding common pitfalls and how to avoid them, you can streamline the process and ensure compliance. Remember, preparation and accurate record-keeping are your best tools against the complexities of tax filing.
