The agency said it had received 6.4 million of the 9.1 million returns sent out, with just a week to go until the 31 January deadline.

A Revenue spokeswoman told AccountancyAge.com: ‘The figures are very similar to last year, and if that continues to be the case we expect to receive in the region of 300,000 returns a day in a last minute rush to file on time.’
Meanwhile, just 61,836 returns have so far been filed electronically.
