NETFILE - "You are reporting income from an
international organization."
During the tax year, you were employed by a prescribed
international organization, such as the United Nations. In the
section "Other deductions", you claimed a
deduction on line 256 - "Additional
deductions" for the net employment income you report from
that organization. Net employment income is your employment income
minus the related employment expenses you are claiming.
In this case, you cannot send the federal tax return via
NETFILE. This is one of the CRA restrictions:
