When you incorporate federally and start business in Alberta, you need to register here provincially and obtain CAN (corp access number) with which you can file Alberta Corp Tax Return i.e. AT1, since in Alberta you need to file a separate return and pay provincial taxes under your CAN unlike ON/BC/MB where no provincial returns are filed separately.
Hi Tim
Yes - I believe you talking about SIC gir Alberta corp tac - which refers to the Standard Industrial Classification (SIC) Code. You must provide this 4-digit numeric code on Line 028 of your Alberta Corporate Income Tax Return (AT1) to officially classify your business’s primary nature of operations.
Just like t2125 self employee reporting needs classifications fir what type business they do - 6 numbers though -
Whether the corporation is registered provincially or federally is mostly irrelevant (for us tax practitioners). The corporate taxes work the same, no matter how or where the corp is legally registered.
If the “head office” is located in Alberta, the corp will need to file both a T2 (to CRA) and an AT1 (to TRA - Alberta Treasury Board).
Similarly, if the “head office” is located in Quebec, there is a separate Quebec tax return required, though I don’t know what the return is called or where you send it, because I’ve never done one.
Saskatchewan is in the process of setting up a corporate tax department as well, but the gov’t hasn’t announced a date when we will have to start filing separate provincial corporate tax returns.
