The Revenue inquiry into Ansbacher has netted 25.6 million to date, according to a Revenue spokeswoman. It involves 289 cases.

There have been 51 settlements concluded and there have been 25 payments on account.

The spokeswoman said that, of the cases examined, it has been established that 62 involved non-residents, including 17 former Irish residents, and in 12 cases the persons involved availed of the 1993 tax amnesty.

In four cases, there had been insufficient evidence available to establish the identities of the account-holders.
