Frequently Asked Questions
Straight answers about self-employed tax, registration and our fixed-fee service.
Our service includes reviewing your income and allowable expenses, preparing your Self Assessment Tax Return, checking the figures for accuracy, and submitting the return to HMRC. We handle the process from start to finish so you do not have to deal with the forms yourself.
You may need to file if you are self-employed, a sole trader, a freelancer, a contractor, a landlord, a company director, or if you have additional income that is not taxed at source. Not everyone in these situations will need to file, so it is worth checking your position with us if you are unsure.
You provide your income and expense details online, and we review the information relevant to your tax return. We then prepare your Self Assessment Tax Return, check it carefully, and submit it to HMRC on your behalf. You can get support throughout the process without needing to visit an office.
You will need to provide details of your income, such as self-employment earnings, rental income, or other taxable income, along with records of allowable expenses. We may also ask for relevant documents like invoices, receipts, and bank statements to ensure your return is accurate and complete.
Allowable expenses are costs that are wholly and exclusively for your business, such as office supplies, travel for work, and professional fees. We review your records to identify relevant expenses and include appropriate claims on your return, helping to ensure it is accurate and compliant.
We prepare your return based on the information you provide and check it against HMRC rules and deadlines. Our accountants stay up to date with current requirements, so your Self Assessment Tax Return is submitted correctly and on time, reducing the risk of errors or penalties.
The deadline for online Self Assessment Tax Returns is 31 January following the end of the tax year. If you need help meeting this deadline, we can prepare and submit your return in good time. It is best to provide your information early so there is no last-minute rush.
Getting started is simple: contact us with your details, and we will guide you through what information we need. Once you provide your income and expense records, we will prepare your Self Assessment Tax Return and handle the submission to HMRC. You can then relax knowing your tax affairs are in order.
