Under the Inland Revenue's Self Assessment regime, the onus is now on the taxpayer, to complete and file the return accurately and on time. Failure to do so will result in a system of increasing penalties. It is therefore essential that all taxpayers who receive the Self Assessment Returns take a professional approach in completion and submission of these returns.

Corporation Tax Self Assessment (CTSA) is now in operation. It applies to accounting periods ending on or after 1 July 1999. It completes the self assessment reforms introduced for individuals four years ago by extending the principles of self assessment to company tax returns.
However, for most companies the process of moving to CTSA is straightforward. This is because the Pay and File rules for the submission of returns and the payment of tax are substantially unchanged.
