With the self assessment deadline fast approaching, HMRC has asked that when using the online service, taxpayers file returns during off-peak periods wherever possible.
Thses are expected to be any time on Saturday 26 and Sunday 27 January, and between 5pm and 8am on weekdays.
HMRC say 'it's an imperative agent filers if at all possible file their clients self assessment returns outside of the peak periods, which are 10am to 12 noon (sic) weekday mornings (sic), and also mid-afternoons.
'The last week coming up to the deadline will be particularly busy so is best avoided if at all possible.'
Every year HMRC exhort advisers not to file returns during peak times, completely overlooking the fact that in reality, they will have no option but to do so.
Last year, the system coped well with the pressure, it is to be hoped that it will do so again this year.
HMRC added, with regard to the availability of online filing during the peak period, advisers should view the service availability page entry for self assessment which can be accessed via the link on homepage of the HMRC website.
There is no planned downtime in January 2008 but if the system should be unavailable for any reason HMRC say that they will give details here.
They 'strongly encourage customers encountering problems to look at the service issues page (accessed via a link on the service availability page) before reporting problems to the helpdesk.
'This page will show details of any known problems with the SA Online service and will give advice on how to self-help wherever possible.'
HMRC add that 'changes to our publishing process mean that we will be able to update the information on this page more quickly than in previous years if we do have any problems'.
HMRC have put a range of measures in place in preparation for the January peak. These include:
- System capacity upgrades
- Putting in place a change freeze on the e-infrastructure from November until the end of January
- Putting additional technical support in place
- Implementing several contingency measures such as stand-by power supplies to protect key systems
- Improving systems in place since 2007 giving them a greater ability to monitor the live service capability allowing us to identify and respond to problems more effectively
