Who this is for

This is suited to sole traders, freelancers and individuals who must file on paper or prefer to do so for this tax year. It is especially useful if you have multiple income sources, are unsure what you can claim, or you have fallen behind on record keeping.

How the process works

You will be asked for a shortlist of information first, then you will receive a tailored records checklist. Once your figures are pulled together, the return is completed and checked, and you will get clear instructions on how to submit it by post in time for 31 October. If anything is missing or unclear, you will be told exactly what is needed and why.

What happens after the return is submitted

You will be guided on what to keep for your records and how to track key dates for payment. Where appropriate, you will also get practical suggestions to make next year easier, such as improving your expense tracking and moving to a smoother, more predictable process.
