The new penalties will be slapped on offshore investors who evade tax by failing to tell HMRC about the full extent of their holdings.
HMRC says the rules will apply to anyone who does not reveal information about income or gains arising from:
- Income from a source outside the UK
- Assets held outside the UK
- Financial transactions carried on outside the UK
The penalty rules apply to inaccuracies in tax returns or other documents relating to the tax year running from April 6, 2011 until April 5, 2012 or later filed with HMRC.
These tax returns are due for filing between now and January 31, 2013.
HMRC will charge a minimum 100% tax penalty for an inaccuracy in a return or document, a failure to notify a tax liability and the deliberate withholding of information where a tax return is more than 12 months late.
In territories which do not share information with HMRC, deliberate or concealed gains will be subject to a maximum 200% tax penalty.
The penalties will not apply to taxpayers filing information about their offshore finances under a disclosure agreement – like the current scheme involving investors with funds in Liechtenstein.
The rules apply to UK taxpayers and expats living overseas who are still classed as UK residents and cover income tax and capital gains tax.

The penalty warning follows the UK and Switzerland agreeing to settle a tax dispute over investments held by wealthy Britons with Swiss private banks.
The deal means the taxpayers must declare their income to HMRC or pay tax that covers past failures to reveal undeclared assets.
