This Is the Third of Three Catch-Up Tools
The family has two already and they answer different questions, so it is worth saying which is which rather than leaving you to find out.
The unfiled years checker works out which years are outstanding. The unfiled years cost calculator gives what the whole catch-up costs. This page gives the dated schedule: a row per year, with its deadline and how overdue it is.

Oldest First Is Not a Preference
Each year’s return opens from the closing balances of the one before it: retained earnings, the undepreciated balance on Schedule 8, the loss continuity. A year filed out of order carries opening figures that have not been established.
That is why the schedule is numbered. The order is part of the work rather than a tidy way of presenting it, and the retained earnings rollforward calculator is what carries one year’s closing figure into the next.
Prepared in Order, Transmitted Together
The years are prepared in sequence and can then be transmitted in one sitting. You sign one Form T183CORP for each year, because each year is its own return and each transmission needs its own signature.
Each year is $300.00 plus HST per tax year, so the total is the number of years at that price. There is no discount for volume and no part-year rate: a three-month stub period is a return like any other.
What the Overdue Column Does and Does Not Say
It counts days past the filing deadline, which is a fact about the calendar. It is not a penalty calculation and it does not grow into one on a true nil year.
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.
The nil return late penalty checker works through that distinction properly, and the guide to catching up on unfiled corporate tax returns sets out the whole process.
Frequently Asked Questions
How do I catch up on several unfiled T2 returns?
Oldest first, because each year opens from the closing balances of the one before it. Once prepared they can be transmitted together.
How much does a catch-up cost?
Each tax year is its own return at $300.00 plus HST per tax year, so the total is the number of outstanding years at that price.
Can several years be filed at once?
They are prepared in order and can then be transmitted in one sitting. You sign one Form T183CORP for each year.
Does an unfiled year eventually expire?
No. It stays open, invites a demand to file and an arbitrary assessment, and blocks a clearance certificate until it is filed.
Does the overdue count mean I owe a penalty?
It counts days past the deadline, not money. On a true nil year the percentage late-filing penalty is a percentage of tax owing, and the corporation owes $0.00.
