Tax Returns
Filing an annual self-assessment tax return is a necessity for anyone who is self-employed or runs their own business. We take the hassle away.
The service
With increasing powers given to HMRC, avoiding the tax man could land you in jail. As a business owner you are responsible for making sure that you are paying the right amount of tax and that this is done on time every year. It means keeping records of all payments and expenses as well as working out any tax deductions.

Areas we serve
Self assessment and corporate tax returns are prepared from your records, reviewed with you before anything is sent, and filed with HMRC in time for the deadline. If there are allowances or reliefs you are entitled to, they are applied as part of the work, not offered as an extra.
If HMRC opens an enquiry we deal with the correspondence for you. Tax investigation work is one of our additional services, and it is handled by the same people who prepared the return, so nothing has to be explained twice.
