Input: Consider Input: Whistleblower Herve Falciani has said the UK government should have known about the scandal in 2010.
Committee chairman Andrew Tyrie said the committee was concerned about the allegations and had decided to take oral evidence from both HSBC and HMRC.
Meanwhile, the BBC understands the Treasury is preparing legislation to tighten the tax evasion laws.
BBC business editor Kamal Ahmed has been told that it is preparing legislation to tighten the rules on undeclared income held in offshore accounts.
The chancellor made it clear last April that he would like to toughen the rules over tax evasion including offshore banking.
Since then there has been international agreement on the automatic exchange of information regarding tax matters, but no unilateral steps from the UK government.
Mr Tyrie said the committee would be probing whether banks had made adequate progress in changing their own practices.
"Banks have repeatedly told the committee that, since the crisis, they have put in place reforms to ensure that they operate on the basis of sharply improved standards," he said
"The committee will need reassurance that they have done so in private banking."
Mr Falciani, a former IT worker for HSBC, said UK tax authorities would have known about the stolen list of clients of HSBC's Swiss private bank when it was given to French officials.
The BBC has also learned the UK tax authority is to expand its inquiry. HMRC will meet the police and the Serious Fraud Office later in the week.
Speaking to BBC Radio 4's Today programme, Mr Falciani said French authorities had got in touch with HM Revenue & Customs and passed on information in 2010.
He said the UK government should have known the bank itself was doing wrong in 2010.
"By that time I (had) already declared and explained the problems that were happening," he said.
"It was made public at that time and of course I already at that time explained the major, huge issues we were foreseeing inside HSBC," he added.
Asked if the information Mr Falciani had provided in 2010 was also about the behaviour of the bank, as well as individuals, he said: "It was exactly about the behaviour and containing all the required information for an internal audit."
He said there was much more to be shared and that co-operation between European tax authorities would reveal far more evidence.
His latest revelations follow angry exchanges on Wednesday, when MPs accused tax officials of failing to deal with issues adequately.
Top officials from HM Revenue & Customs were shouted down by MPs, angry at what they said was a lack of urgency in tackling the HSBC tax-dodging scandal.
Margaret Hodge, chairwoman of the Public Accounts Committee, accused Lin Homer, HMRC chief executive, of a "pathetic response".
Herve Falciani's interview on the Today programme has raised two important issues.
Firstly, that he offered information in 2010 to UK authorities that HSBC was involved in aiding and abetting tax evasion for its clients.
The government says that all it knew about were the publicly reported facts that clients of HSBC's Swiss bank were being investigated over their tax affairs.
And that meant there was no reason to prevent Lord Green, the former chairman of HSBC, becoming the new trade minister.
Secondly, that HSBC's Swiss bank controls in the 2000s were in a mess and that failing computer systems made it impossible for the bank to have "sufficient oversight".
This is vital, because allegations of lack of control and oversight are toxic for any bank and its board.
Don't forget, HSBC was fined nearly Â£1.2bn for governance failures over money laundering allegations in its Mexico operation.
HSBC says that controls have been improved in its Swiss operation. The question is: if Mr Falciani is correct, why were they allowed to get into such a mess in the first place?
Ms Homer denied she had failed to take firm action against UK citizens hiding money in HSBC accounts in Geneva.
She said it was "absolutely not the case" she was failing the UK taxpayer.
Ms Homer explained why there had been only one prosecution of someone whose hidden accounts in Switzerland had been revealed.
She said that most of the information leaked via the French authorities in 2010, which involved about 3,600 UK individuals, was incomplete or "dirty" data.
Of these, 3,200 individuals had been traced and, of the 1,100 most serious cases - which HMRC had chosen to pursue - only 130 were now outstanding.
From the rest of those cases, Â£135m had been recovered, Ms Homer said.
"We were speedy and on the case," she told the MPs.
She explained that in fact, two-thirds of the total group of UK-based HSBC account holders "were found to be compliant" with UK tax rules, in some cases because they had non-dom status.

Output: The UK's Treasury Committee is to examine allegations that HSBC's Swiss private bank helped clients evade tax.


Input: Consider Input: Avijit Roy, an atheist who advocated secularism, was attacked as he walked back from a book fair with his wife, who was also hurt in the attack.
No-one has been arrested but police say they are investigating a local Islamist group that praised the killing.
Hundreds of people gathered in Dhaka to mourn the blogger's death.
Mr Roy's family say he received threats after publishing articles promoting secular views, science and social issues on his Bengali-language blog, Mukto-mona (Free Mind).
He defended atheism in a recent Facebook post, calling it a "rational concept to oppose any unscientific and irrational belief".
His Mukto-mona website on Friday bore the message in Bengali "we are grieving but we shall overcome" against a black background.
US State Department spokeswoman Jen Psaki described it as an assault on Bangladesh's proud tradition of free intellectual and religious speech.
A group of men ambushed the couple, who live in the US and were visiting Dhaka only to attend the book festival, as they walked toward a roadside tea stall.
At least two of the attackers hit the couple with meat cleavers in the attack on Thursday evening, police chief Sirajul Islam told AP news agency.
Dropping their weapons, the attackers ran away, disappearing into the crowds.
Police told the BBC they were investigating a local hard-line religious group that had praised the killing in an online message.
Ajay Roy, father of the dead man, urged the authorities to find the killers and "ensure exemplary punishment".
"This Bangladesh which was built  by the blood-sacrifice of the martyrs has now turned into a den of militants," he said.
Students, teachers and bloggers gathered at Dhaka University on Friday to protest against the killing.
In a forthcoming article to be published in the Free Inquiry magazine of April-May 2015, Mr Roy likens religious extremism to a "highly contagious virus".
He says he received threats from Islamist hardliners in Bangladesh last year when his book, The Virus of Faith, was released at a book fair.
"The death threats started flowing to my e-mail inbox on a regular basis," he writes.
"I suddenly found myself a target of militant Islamists and terrorists. A well-known extremist... openly issued death threats to me through his numerous Facebook entries.
"In one widely circulated status, he writes, 'Avijit Roy lives in America and so, it is not possible to kill him right now. But he will be murdered when he comes back.'"
The killing in early 2013 of another secular blogger, Ahmed Rajib Haider, which was blamed on religious hardliners, sparked protests from free-speech supporters and counter-protests from Islamists.
The police say the attack on Mr Roy was similar to the 2013 murder.
Avijit Roy
Death threats against atheist writers and bloggers are nothing new in Bangladesh.
Prominent writer Taslima Nasreen had to leave Bangladesh after she received death threats from hard-line Islamists in the mid-1990s.
She wrote on her blog: "Avijit Roy has been killed the way other free thinker writers were killed in Bangladesh. No free thinker is safe in Bangladesh.
"Islamic terrorists can do whatever they like. They can kill people with no qualms whatsoever."

Output: Attackers in the Bangladeshi capital Dhaka have hacked to death a US-Bangladeshi blogger whose writings on religion angered Islamist hardliners.


Input: Consider Input: Mr Pu was found guilty by a Beijing court earlier on Tuesday for "inciting ethnic hatred" and "picking quarrels" in social media posts.
The court sentenced him to three years in prison but also said the sentence would be suspended.
He is the latest to be tried in a crackdown on dissidents in China.
Mr Pu was released from Beijing's Number One Detention Centre on Tuesday afternoon, where he had been held for 19 months.
He is now under "residential surveillance", and has 10 days to decide whether to appeal against his conviction and sentence, his lawyer says.
Experts say the suspended sentence means Mr Pu can avoid serving time in jail - but could be monitored during the suspension period. The guilty verdict means he can no longer practice law.
Mr Pu could have faced a maximum sentence of eight years in prison.
State news agency Xinhua said that during his sentencing Mr Pu had "acknowledged the reality of his crimes", apologised, and accepted his sentence. However, his lawyers said he had not pleaded guilty.
Rights group Amnesty International said that the sentence was "a deliberate attempt by the Chinese authorities to shackle a champion of freedom of expression".
However, foreign ministry spokesman Hong Lei said Mr Pu's case had been handled "in accordance with the law" and that "foreign governments should respect China's judicial sovereignty".
Mr Pu has been in detention since May 2014, after he posted several messages on microblogging platform Weibo that were critical of the government.
He had questioned the "excessively violent" crackdown on Uighurs in the restive Xinjiang region, alleged the Chinese Communist Party was an untruthful party, and mocked government rhetoric over disputed islands in the East China Sea.
Supporters say his arrest was politically motivated, as he is known for representing dissidents in sensitive human rights cases.
Pu Zhiqiang represented artist Ai Weiwei in a tax evasion case that critics complained was politically motivated. He also campaigned for the eventual abolition of the labour camp system, under which suspects could be detained for years without trial.
Prior to the sentencing, a small group of activists and foreign journalists gathered in front of the court. There were brief scuffles with the police, in a repeat of scenes seen last week during Mr Pu's one-day trial.
A BBC team witnessed supporters and journalists being dragged away by dozens of plainclothes policemen. The BBC team was later asked to leave.
Amnesty said at least 12 activists were detained on Tuesday.
Human rights activist Hu Jia told the BBC that China's authorities had "attacked a leading human rights lawyer... as a warning to other rights lawyers [in China]."
International interest in his case could have contributed to his jail sentence being suspended, Mr Hu said, but added that Mr Pu was still at risk of being persecuted by the authorities.
Pu Zhiqiang is something of a celebrity as a lawyer. He's a big, bear-like man with a baritone voice who has defended a range of causes, especially those involving freedom of speech and detention in labour camps.
He mixes popular street speech with allusions to classical literature in a powerful rhetorical fashion. "Feisty" is an adjective often used to describe him.
He has also been a thorn in the side of the authorities since his imprisonment in 1989 as a student pro-democracy protester.
His defenders say his current treatment is not because of the content of the seven posts on social media cited by the authorities. Rather, they say, it is to send a warning to dissidents - and the lawyers of dissidents.


Output: Prominent Chinese human rights lawyer Pu Zhiqiang has been released from detention after receiving a suspended jail sentence.
