A breakthrough deal to recover lost tax from Britons holding bank accounts in Liechtenstein will net £1bn, Chancellor¹ Alistair Darling has said.

英国大臣Alistair Darling称，大不列颠人在列支敦士登所持银行账户所收税款协议取得突破并获利10亿英镑。

Liechtenstein has come under pressure to open up its financial records

HM Revenue & Customs struck an agreement last month with the Alpine² tax haven³ to exchange information.

Up to 5,000 British investors⁴ are thought to have funds in secret accounts in the country - which would mean an average pay-back of £200,000.

The Revenue has requested details of 100,000 offshore⁵ accounts worldwide.

Tackling offshore evasion⁶ tax evasion and tax havens⁷（避税掩护所） was "not only fair" but "particularly important... especially at a time when we expect public spending in the period ahead to be tighter", Mr Darling told the CBI Scotland annual dinner.

Pressure

Under the Liechtenstein arrangement, investors will be offered the chance to volunteer details of their deposits in return for penalties, capped at 10% of tax evaded⁸ over the past 10 years.

HMRC said that those who failed to make a full disclosure would have their accounts closed down and risked losing all their savings⁹.

Liechtenstein was once seen as one of the most secretive jurisdictions¹⁰（司法权）, favoured by the wealthy looking to shelter money from their own tax authorities.

However, it came under pressure last year after the German government obtained a list of wealthy Germans with money invested there.

More generally, pressure has mounted on tax havens to share information since April's G20 Summit and similar deals have already been struck with the US and Germany.

Miscreants¹¹ who confess will find the cash they have to hand over to HMRC will not be limited to just the penalty of 10%.

They will have to repay all the tax they should have paid in the first place, up to 10 years.

And they will also have to pay interest, which could turn out to be worth far more than the formal penalty charge.

Havens targeted

Governments are particularly keen to trace and recover unpaid¹² revenues as tax receipts（纳税收入） fall in the global recession.

In April, the UK government launched a second push to squeeze millions of pounds in unpaid tax from UK citizens with offshore accounts.

It has already signed agreements with tax havens such as Jersey¹³, Guernsey, Isle¹⁴ of Man, and the British Virgin¹⁵ Islands to allow the exchange of financial information on UK residents.

The Revenue's first disclosure campaign in 2007 raised £450m from 45,000 people.

That targeted offshore accounts held by the customers of the UK's big High Street banks.
