Frequently Asked Questions
Straight answers about self-employed tax, registration and our fixed-fee service.
The service covers reviewing your income and allowable expenses, preparing the Self Assessment Tax Return, checking the figures for accuracy and submitting the completed return to HMRC. We handle the preparation side and keep you informed as the return progresses.
Self-employed individuals, sole traders, freelancers, contractors, landlords, company directors and people with additional income may need to file, depending on their circumstances. If you are unsure whether a return applies to you, we can review your situation and explain what is required.
You provide your income and expense details, and we review the information before preparing your return. Once everything is checked and accurate, we submit it to HMRC on your behalf. You do not need to deal with the filing yourself.
You will need details of your income, such as invoices, bank statements or payment records, along with information on relevant expenses. If you have other income sources, including rental or dividend income, those details should be included too so the return is complete.
Allowable expenses generally include costs that are wholly and exclusively for your business, such as office supplies, travel for work, professional fees and certain equipment. We review your expenses and identify relevant claims so your return reflects your circumstances accurately.
We prepare your return using the details you provide and check the figures carefully before submission. The return is completed in line with HMRC requirements, which helps reduce the risk of errors or queries after filing. If anything needs clarifying, we will ask before submitting.
The deadline for filing an online Self Assessment Tax Return is normally 31 January following the end of the tax year, with payment usually due by the same date. Registering with HMRC and gathering your records early helps avoid last-minute problems.
You can start by sending us your income and expense details through our online service. We will review the information, prepare your Self Assessment Tax Return and keep you updated until it is submitted to HMRC. Getting in touch early gives more time to sort everything properly.
