Online tax calculator falls over

From about midday the calculator was displaying an error message to some users saying it was unavailable reports The BBC.

A spokesman for HM Revenue & Customs (HMRC) said 400,000 people had tried to use the site during the morning.

“Our online calculator is extremely busy at this time but a full service is being restored,” he said.

“The mobile app is unaffected,” he said.

The new services was launched as part of the government’s plan to improve the transparency of government finances.

Labour said the system did not include VAT or recent changes to tax credits and child benefits.

The service is available via apps downloaded to smartphones and, in theory, on the HM Revenue & Customs (HMRC) website.

Last year the Treasury announced that from 2014-15 every taxpayer would be sent a printed statement showing exactly how much tax and national insurance they had paid and how it had been spent.

The spending will be broken down by categories such as welfare, health, education, defence and the repayment of government debt.

“We think it is right that people know how much tax they pay and what the government spends it on,” said David Gauke, Exchequer Secretary to the Treasury.

“At the moment, over half of taxpayers do not know how much income tax and national insurance they pay in a year.

“Our new tax calculator will allow them to find out, which is a big step towards a more transparent, twenty-first century system,” he added.
