Self-employed individuals, sole traders, freelancers, contractors, landlords, company directors and people with untaxed additional income may need to file. Not everyone in these groups automatically needs to submit a return, so it is worth checking your situation before assuming you do or do not need to file.
You provide your income and expense details, and we review the relevant information for your return. We then prepare the Self Assessment Tax Return, check it for accuracy and submit it to HMRC once you are happy with everything.

The main Self Assessment deadline for online returns is 31 January following the end of the tax year, with a separate deadline for paper returns earlier in the year. It is best to prepare well ahead so there is time to gather information and avoid last-minute pressure.
