Frequently Asked Questions
Straight answers about self-employed tax, registration and our fixed-fee service.
We review your income and allowable expenses, prepare the return, check the figures for accuracy and submit everything to HMRC on your behalf. You provide the information, and we handle the preparation and filing so you know it has been done properly.
Self-employed individuals, sole traders, freelancers, contractors, landlords, company directors and people with untaxed income may need to file. Not everyone in these groups has to file, so it is worth checking your position if you are unsure.
You send us your income and expense details, and we review what is relevant to your return. We prepare the Self Assessment Tax Return, check it carefully and submit it to HMRC once you have confirmed the information is correct.
You will usually need details of your income, any allowable expenses, and records such as invoices, receipts or bank statements. If you have other income sources, such as rental income or dividends, include those details as well so nothing is missed.
Allowable expenses generally include costs that are wholly and exclusively for your business, such as office costs, travel for work, professional fees and certain equipment. We review your records and identify relevant claims so your return reflects your circumstances accurately.
We prepare your Self Assessment Tax Return in line with HMRC rules and check the information before submission. Our aim is to make sure the return is accurate, complete and filed correctly, reducing the risk of avoidable errors or follow-up queries.
Online returns and any tax owed are generally due by 31 January following the end of the tax year. Registering with HMRC and gathering your records early helps avoid last-minute problems, so it is worth starting the process well before the deadline.
