Corporation income tax

Generally, you need approval from us to change a corporation's fiscal year-end or fiscal period. Also, a corporation that becomes bankrupt must get our approval to change its fiscal period.

To change an established fiscal period:

• Write a letter to your tax services office asking for approval.
• Explain the reasons for the change.

However, you do not need approval to change the fiscal period in some situations, including the following:

• The corporation has gone through a wind-up and you are filing its final return with an abbreviated fiscal period.
• The corporation has to end its tax year at a certain time because it is emigrating to another country, becoming exempt from tax, or ceasing to be exempt from tax.
• A person or a group of persons acquired control of the corporation under subsection 249(4).
