Change of fiscal period (year-end change)

A change of fiscal period is a change in the date a business’s tax year ends. Section 249.1(7) of the Income Tax Act says no change in when a fiscal period ends may be made for the purposes of the Act without the Minister’s concurrence. The CRA lists situations where approval is not needed.

A buyer meets this after closing, when it wants the target’s year-end to match its own. The CRA says that generally, unless approval to change the tax year-end has been received, a corporation’s fiscal period is the same from year to year. For a corporation, section 249.1(1) says no fiscal period may end more than 53 weeks after it began.

How a change is requested

The CRA says to write a letter to your tax services office asking for approval, explaining the reasons for the change and its effective date. It also lists situations where approval is not needed, including a dissolution with a final return, a year-end forced by emigration or a change in tax-exempt status, and an acquisition of control under subsection 249(4). A bankrupt corporation must get the CRA’s approval.

What to ask

  • Whether the purchase itself ended the target’s tax year under the acquisition-of-control rule
  • Whether a further change needs the CRA’s approval, and who will write the request
  • How the new year-end affects T2 filing dates and any group schedules
