Top Tips for Sole Traders with One Customer



Navigating HMRC compliance as a sole trader can be challenging, more so when you have only one customer. While it may sound straightforward, you must follow specific rules and regulations to avoid any potential pitfalls. From maintaining proper records to understanding your tax obligations, ensuring compliance requires diligence and understanding. In this article, we'll explore crucial tips that can help you stay compliant with HMRC as a sole trader with a single client. 


Let's delve into useful practices such as effective record-keeping, understanding allowable expenses, and timely tax return submissions. With the help of the Pie Tax App and our team of expert tax assistants, you can make this often daunting task much more manageable.

Maintain Accurate Records

Keeping precise records is vital for HMRC compliance. As a sole trader, ensure that you document every transaction you make, including expenses and income. This not only helps you at tax time but also provides a clear picture of your financial health.

Understand Tax Deadlines

Meeting tax deadlines is crucial to avoid penalties. HMRC expects timely submissions of your Self-Assessment tax return by the 31st of January each year. Set reminders and use digital tools to ensure you never miss a deadline.

If your annual turnover exceeds £85,000, you must register for VAT. This not only affects your pricing but also adds complexity to your accounting obligations. Be sure to monitor your income regularly.

Recognise Allowable Expenses

Recognising allowable expenses is fundamental to reducing your tax liabilities. Expenses like office supplies, travel costs, and even part of your household bills (if you work from home) can be claimed. However, remember to save all receipts and invoices as HMRC may request evidence during an audit.


Understanding the scope of what you can claim ensures you legitimately reduce your tax bill, helping you reinvest in your business. It's also an area where the expert tax assistants available on the Pie app can provide valuable guidance.

Handle HMRC Inquiries

If HMRC raises a query about your tax return, respond promptly and accurately. Ignoring an inquiry or providing incomplete information can result in severe penalties. Your primary goal should be to supply the requested documents and information as quickly as possible.


The Pie Tax App simplifies this process by allowing you to keep all your financial documents in one place, which can be easily accessed when required. Not to mention, the expert tax assistants available on the Pie app are there to offer advice and support, reducing your stress and ensuring compliance.

Understanding IR35 Legislation and Ensuring Compliance

IR35 legislation, introduced by HMRC, aims to identify "disguised employees" who work as contractors through their own limited companies but would otherwise be considered employees if the intermediary was not used. The legislation ensures that these individuals pay similar taxes to regular employees. IR35 rules apply to all sectors, and non-compliance can result in substantial tax liabilities and penalties. It's crucial for contractors to understand their status under IR35 to avoid unexpected financial consequences.


To remain compliant with IR35, it is essential to accurately assess your employment status for each contract. Factors such as the level of control your client has over your work, your ability to provide a substitute, and the mutuality of obligation should be considered. Use HMRC’s Check Employment Status for Tax (CEST) tool to evaluate your status. Additionally, maintain clear and detailed contracts that reflect your working practices and keep thorough records of your business activities. Seeking advice from a tax professional or using services like the Pie Tax App can also help ensure compliance and provide peace of mind.
