Correcting efile errors

The preparer is responsible for correcting any efile errors in rejected returns. Once corrective steps have been taken, a return can be retransmitted.

If, however, changes made to the personal income tax return alter the refund or balance owing by more than $300, a new efile authorization form (T183 or TP-1000.TE) must be completed and signed by the taxpayer.

Also note that if an efile error cannot be corrected, the return will have to be printed and filed on paper.

Each government's efile program has its own list of efile errors:

• CRA T1 efile error messages can be found in Chapter 2 of the CRA's electronic filers manual.

• CRA T1 ReFILE error messages can be found here.

• CRA T1 EFILE Online web service error messages can be found here.

In DT Max, see Overriding T1 efile records for help on correcting certain errors.
