The London crackdown on wealthy tax evaders follows a similar campaign run in the North of England last October say Harris & Co accountants Northampton.
The taskforce will focus its attention on individuals and businesses with offshore accounts and those living lifestyles beyond their obvious means through assets from undeclared income.
A similar taskforce will also focus on South Wales, while other taskforces will target restaurants in London and East Anglia, and the construction industry in the Midlands.
A further 30 taskforces are planned for 2014-15.
HMRC is also running the third stage of the tax evasion advertising campaign, using advertising, radio, train car panels, washroom posters and mirror stickers.
