Form T183CORP is used to allow an electronic filer to electronically file a corporation income tax return to the CRA. This form must be completed for every initial and amended T2 Corporation Income Tax Return electronically filed to the Canada Revenue Agency (CRA) on your behalf.
By completing Part 2 and signing Part 3, the corporation acknowledges that, according to section 150.1(4) of the Income Tax Act, if someone other than the corporation (required filer) is going to transmit the tax return electronically, an authorized signing officer of the corporation must complete and sign a Form T183CORP before the tax return is transmitted.
Part 4 must be completed by either the corporation or the preparer of the corporation income tax return. If "3rd party (i.e. accounting firm)" was selected in the Tax Preparer’s Profile form, the transmitter name and address entered will be displayed in Part 4 of Form T183CORP.
Do not submit Form T183CORP unless the CRA asks for it. The corporation keeps the copy of the signed form for their records. It must be kept for at least six years following the date that the return was filed.
The CRA is responsible for ensuring the confidentiality of the corporation’s electronically filed tax information only after the CRA has accepted it.
