EFILE multiple years

When selected, this feature alerts the CRA that multiple tax years for the same taxpayer are being transmitted, for tax years 2013 and later:

This allows the returns to be assessed in order of year, rather than when the returns are received.

Note: Each tax year must still be individually transmitted. The option only flags the returns to be processed together and in order. We recommend that the returns be sent in order, and within 24 hours.
