The Inland Revenue has delayed the go-live date of key modules in its update of the Pay As You Earn (PAYE) computer systems to allow for further testing.
The employer mainten-ance business service module of the Revenue's Computer Support for PAYE (CSP) system was due to hit the desktops at the beginning of April, but has been put back to the end of May. As a result, a second module, due to be launched in July, has been delayed until an unspecified time later in the year.
CSP is being rolled out over three years to replace the existing 15-year-old COP system. As each new module hits the desktop the corresponding functions it replaces are switched off.
This means the two systems must run side-by-side until the roll-out is complete. A spokesman told Computer Weekly, "The two systems have to run concurrently, they are very large systems and given that they have to work together, there are very complex integration issues.
"We have taken a prudent judgement about deferring the release so we can undertake further testing and proceed with confidence."
The CSP system will give computer support for the collection of student loans and Working Families' Tax Credit.
