Amalgamation (corporations)

An amalgamation takes place when two or more corporations, known as predecessor corporations, combine their businesses to form a new successor corporation.

Corporations Canada and the provincial and territorial governments approve all corporate amalgamations.

The CRA accepts either of the following as proof of amalgamation:

Send either proof of amalgamation to your tax centre.

Based on the information received, the CRA makes the necessary changes to the old business numbers (BN) including the corporation income tax accounts, and, if necessary, register a new BN and CRA accounts for the newly created corporation.

If you want to keep the BN of one of the old corporations, send a letter to your tax services office or tax centre to tell the CRA which number to keep. However, if one of the corporations is non-resident, you have to apply for a new BN.

Several topics below explain how an amalgamation may have an effect on many of your dealings with the CRA.
