The Tax Years Stop at the Dissolution Date
Dissolution ends the corporation, and with it the sequence of tax years. The final period runs to the dissolution date and its return is due six months after that date. No period after it is a tax year, so there is nothing further to file.
What dissolution does not do is clear what came before. A year that was unfiled on the day of dissolution is unfiled afterwards, and it is still the corporation’s year.
Which Periods Are Owed and Which Are Not
| Period | Return owed? | Deadline |
|---|---|---|
| Each full tax year before the final one | Yes, until filed | Six months after each year-end |
| The final period, ending on the dissolution date | Yes, the final T2 | Six months after the dissolution date |
| Any period after the dissolution date | No | No tax year arises |
| A year already filed and assessed | No | Closed, unless adjusted |
The final T2 return due date calculator dates the final return on its own, and the dissolution timeline calculator puts it in the order of the wind-up steps around it.
The Earlier Years Come First
A T2 carries figures forward from the year before it, so outstanding years are filed oldest first and the final return goes last. Filing the final return on top of a gap leaves the gap where it was, and an unfiled year blocks both a clearance certificate and the dissolution itself.
A true nil return carries no percentage late-filing penalty, because that penalty is a percentage of tax owing and the corporation owes $0.00. The unfiled year still stays open forever, invites a demand to file and an arbitrary assessment, blocks a clearance certificate and dissolution, and costs a non-resident-owned corporation $25.00 per day up to $2,500.00.
Frequently Asked Questions
Does a dissolved corporation owe returns for later years?
No. The final period ends on the dissolution date and no tax year arises after it, so there is nothing further to file.
When is the final T2 due?
Six months after the date of dissolution. Where that date falls on a Saturday, a Sunday or a public holiday recognised by the Canada Revenue Agency, a return received by the next business day is on time.
Does dissolution clear the years that were never filed?
No. Those years stay open and stay the corporation’s, and they block a clearance certificate and the dissolution itself until they are filed.
