Introduction to Self Assessment for Agents

Self Assessment Online is simple, secure and available day or night. You can see details of your clients' liabilities and payments, their latest statements and claim to reduce their payments on account.

As well as being able to view and change your clients' contact details, you can file their tax return with or without accompanying attachments using a range of Internet software, which are available from third party software suppliers. Or you can use HMRC's free product (Online Tax Return - SA).

If you file online you will get more time, for 2007-08 and subsequent years the filing deadlines change to 31 October for paper returns but remain as 31 January for online filers. All the software and online forms check the return as you fill it in and do the calculations for you. You will also get an immediate online acknowledgement.
