Ten new alleged tax-dodgers have been added to the Government's most-wanted list.
Writing for ITV News, Richard Murphy, one of the founders of the Tax Justice Network, says Google is using the law to its advantage.
In a strongly worded report the Public Accounts Committee criticises Google for the way the internet company legally reduces its tax bill.
HM Revenue and Customs (HMRC) has urged parents who have not registered child benefits to do so now to avoid further fines.
This only applies to families where one parent earns £50,000 or more and who have not already opted out of the payments.

Although we are past the deadline, people should still register for self-assessment to minimise any penalties they may face.
Fines for failing to register will be decided on a case-by-case basis, HMRC said.
Tens of thousands of parents could be fined for failing to register the child benefit they received this year with the taxman.
An estimated 165,000 people missed Saturday's deadline, meaning they face penalties as well as losing the handout.
Under Government reforms, households where one parent earns more than £50,000 a year have to return the benefits through the self-assessment system unless they have opted out of receiving it in the first place.
HM Revenue and Customs said the number of parents who had opted out of child benefits altogether had far exceeded expectation.
HM Revenue and Customs (HMRC) has insisted that the tax benefits enjoyed by top civil servants were past of a scheme that is "quite a common practice by employers".
Responding to the Daily Telegraph's report, the department said:
– HM Revenue and Customs (HMRC)
We can't discuss individual cases. However, cars provided by an employer that are available for employee use are a benefit in kind for the employee and are taxable. These rules have been in place for 37 years.
Employers may choose to pay the tax due on the benefit. If so any such payment will constitute an additional benefit - which will also be taxable on the employee.
This is quite a common practice by employers and is a matter between employer and employee. HMRC makes sure all the tax due is paid.
A senior Conservative MP has criticised the reported tax bill benefits enjoyed by senior civil servants in Whitehall.
– Richard Bacon, Tory member of the Commons Public Accounts Committee
Most taxpayers would be surprised to find that this sort of thing is tax-free. These are out of line with what one would expect from the way people in the private sector are treated
Taxpayers are already paying a lot for these people, I don't think they would be expecting to dig into their pocket to pay for the tax on the benefit as well.
Some of Britain's top civil servants are enjoying an effective pay boost of up to £30,000 a year by having part of their tax bills paid out of public funds, The Daily Telegraph has reported.
The newspaper said Government departments were paying the taxes on perks such as official cars, first class rail travel and rent-free accommodation.
HM Revenue and Customs (HMRC) said the rules have been in place since the 1970s and insisted taxpayers do not lose out.
The report said those benefiting from the system included the Cabinet Secretary, Sir Jeremy Heywood, the head of NHS England, Sir David Nicholson, and the former head of the Serious Fraud Office, Phillippa Williamson.
HMRC have created an interactive map that shows where the Government's most wanted tax dodgers are believed to be hiding.
The government has added ten new alleged tax dodgers to its most wanted list, who have cost the taxpayer between £120,000 and £10 million,HMRC claims.
Shadow Treasury minister Catherine McKinnell says the Government needs to do better on tax-evaders:

One year on, it's a huge failure that 18 of the 20 most wanted tax fraudsters have still not been caught.
At a time when families are facing a cost of living crisis, it's even more important that everyone pays their fair share of tax. The Government needs to do better.
Chancellor George Osborne says the Government will not tolerate those who evade paying their taxes:
The new list includes Michael George Voudouri, who pleaded guilty at Glasgow High Court in relation to money laundering linked to VAT fraud but failed to appear for sentencing.
HMRC said the man, aged between 40 and 50, is believed to be residing in northern Cyprus and is estimated to have cost taxpayers £10 million.
Anish Anand, aged between 25 and 35, is also included after failing to appear at Croydon Crown Court in April 2013 in relation to £6 million VAT and film tax credit fraud.
Anand was convicted in his absence last month and is thought to be in the UK.
Another on the list is Michael "Arthur" Fearon, aged between 18 and 25, who was charged in connection with evasion of excise duty on nearly 8.4 million Benson & Hedges cigarettes, according to HMRC.
He is also wanted by the UK Border Agency in connection with money laundering offences and also by Republic of Ireland police for driving offences.
HMRC said he crossed over the border into Northern Ireland driving a Black Mercedes C200 CDI Sport. The department estimates the Northern Irish man has cost taxpayers £2 million and believes he is in the Republic of Ireland.
