HMRC reassured taxpayers and accountants that its Self Assessment Online services will be fully available ahead of the 31 January filing deadline.
AccountingWEB member Mr. Mischief reported getting a "website currently unavailable" response last Thursday evening and asked if other members had been affected. None responded.
HMRC told AccountingWEB its SA site had slowed down between 19:45 and 20:15 due to testing, but was never completely off-line and was back to full capacity immediately afterwards.
"The SA Online system experienced a very limited period of slow functionality due to testing for around 30 minutes. The system remained working, but we apologise to any users who experienced a slow service. Full functionality returned once the test was complete," an HMRC spokesperson said.
So far, Thursday's hiccup is the only one reported to AccountingWEB this month. Some members may recall the difficulties experienced in 2005, but since then the department has invested a lot of time and effort to ensure the online SA system could cope with demand.
January 2012 passed without incident, so there's a good chance HMRC's reassurance that it expects no more downtime will hold true for 2013.
