What IRIS Business Tax can do for you:

Transferring the critical data from clients’ final accounts and dealing with all of the addbacks, disallowable expenses and capital allowances before you can finalise their tax return can be both challenging and time-consuming – not to mention low value. Clients expect the compliance as standard; there is no added value to this work. It doesn’t matter how complicated the legislation is; clients just expect the work to be accurate and on time.

It becomes quick and easy to complete tax returns and computations with this product. There’s almost no data entry required as all data is drawn from the clients’ accounts and addbacks are made automatically. Mapping allows for individual addbacks to be made on a client-by-client basis or globally across all clients and then remembered year on year.
