Frequently Asked Questions
Straight answers about self-employed tax, registration and our fixed-fee service.
We review your income and allowable expenses, prepare your Self Assessment Tax Return and check the figures before submitting it to HMRC. You provide the details, and we handle the preparation and filing. The aim is to make the whole process clear and straightforward.
Self-employed individuals, sole traders, freelancers, contractors, landlords, company directors and people with additional income may need to file, depending on their circumstances. Not everyone in these groups automatically has to submit a return. If you are unsure, we can help you check whether Self Assessment applies to you.
You send us your income and expense information, and we review what is relevant to your return. We then prepare the Self Assessment Tax Return, check it carefully and submit it to HMRC on your behalf. You are kept informed as the return progresses.
You will usually need details of your income, any allowable expenses and other relevant records that affect your tax position. The exact information depends on your circumstances, such as whether you are self-employed, a landlord or a company director. We will tell you what is needed so you can gather it before we prepare the return.
Yes. We review your records and look for relevant allowable expenses that can be included in your Self Assessment Tax Return. Costs that are easy to overlook can make a difference to the figures. Getting these details right helps ensure your return is accurate.
We prepare your Self Assessment Tax Return using the information you provide and check the figures before submission. The return is completed in line with HMRC requirements for the relevant tax year. This helps reduce the risk of errors or queries after filing.
HMRC sets fixed deadlines for filing and paying Self Assessment tax, and missing them can lead to penalties. It is best to have your information ready well before the deadline so there is time to prepare and check the return. We can help you stay on track with the dates that apply to you.
Getting started is simple: send us your income and expense details and we will take it from there. We will review the information, prepare your Self Assessment Tax Return and submit it to HMRC once everything has been checked. You do not need to be local to us, as the service is handled online.
