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 key steps so you do not have to deal with the paperwork alone.
You may need to file if you are self-employed, a sole trader, a freelancer, a contractor, a landlord, a company director or someone with additional income such as dividends or rental income. Not everyone in these groups automatically needs to file, so it is worth checking your situation with us.
You provide your income and expense information, and we review it carefully. We then prepare your return, check everything for accuracy and submit it to HMRC once you are happy. The process is handled online, making it convenient for clients in Lanark.
You will need details of your income, such as invoices, bank statements or payment records, along with records of allowable expenses. If you have other income sources like rental income or dividends, include those details too. Having this information ready helps us prepare your return accurately.
Yes, we review your expenses and identify allowable costs that can be claimed. Many self-employed people miss expenses they are entitled to claim, so we check your records to make sure your return includes appropriate claims. This helps keep your return accurate and complete.
We stay up to date with HMRC rules and prepare your return with accuracy in mind. Every figure is checked before submission, and we make sure the return meets HMRC requirements. This reduces the risk of errors or queries from HMRC.
The deadline for online filing is 31 January following the end of the tax year. If you miss the deadline, penalties may apply, so it is best to prepare early. We can help you stay on track and submit your return before the deadline.
Getting started is simple. Just get in touch with us and we will guide you through the information we need. From there, we handle the preparation and submission, keeping you informed along the way.
