T5018 construction reporting deadline: calendar year or fiscal period?

Confirm the reporting requirement and period

CRA describes T5018 reporting for qualifying construction payments to subcontractors. It is not a rule for every business that hires a contractor. Review the construction-activity and payment conditions with the preparer before enabling a reporting task.

The reporting period can be a calendar year or fiscal period. The filing deadline is six months after that chosen period ends. A calendar-year period ending December 31 ordinarily gives a June 30 filing date; a different period needs a different calculation and any applicable date adjustment.

Prepare the subcontractor record

• Confirm the reporting period actually used for T5018.
• Reconcile relevant contract payments against the books.
• Review recipient information and reportable amounts with the preparer.
• Agree who prepares and submits the information return.
• Keep the submission acknowledgement and any follow-up.

Use the current CRA instructions for the applicable eligibility and amount calculations. An accounts-payable list is useful preparation, but it is not itself a completed information return.

Do not substitute another return's deadline

The T2 return, GST/HST reporting and T5018 can use different periods or filing schedules. Identify the period on each confirmation so that a completed tax-return task does not hide an outstanding construction-information return.

Understand the calendar’s current T5018 scope

Compliance Calendar currently displays calendar-year T5018 reporting and labels that limitation in the profile and calendar notes. It does not offer a separate fiscal-period selector for T5018. If you use a fiscal reporting period, verify and track that deadline separately rather than relying on the displayed June example. The product does not prepare or submit the return.
