Tax is added at the rate for your province.
Years Are Filed Oldest First
Unfiled years are filed oldest first, one return per tax year, so the Canada Revenue Agency assesses them in the order they fell due.
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.
What Each Return Includes
The fee covers one nil T2 for one corporation for one tax year, including the T2 Short where the corporation qualifies, GIFI Schedules 100, 125 and 141 where they are required, Schedule 24 on a first return, Schedule 50 for every shareholder at 10% or more, Schedule 8 and loss continuity, your Form T183CORP package, single-use secure e-signing, CPA review, electronic transmission by a registered EFILE electronic filer, one corrected transmission if the Agency rejects the first one, and your CRA confirmation emailed within 3 business days.
Frequently Asked Questions
Does a Late Year Cost More Than a Current One?
No. A year filed late costs the same as a current one, $300.00 plus HST per tax year, with no late surcharge and no hourly billing.
How Many Years Can Be Filed at Once?
There is no limit in the tool or in the filing. Years are prepared together and transmitted oldest first, one return per tax year.
Is HST Included in the Figure the Calculator Shows?
No. The calculator shows the fee before tax, the number of years multiplied by $300.00. Tax is then added at the rate for your province, because the price is $300.00 plus HST per tax year.
Does Every Unfiled Year Need Its Own Form T183CORP?
Yes. Each tax year is a separate return and carries its own T183CORP, signed before that year is transmitted. All of them are included in the fee for those years.
What If One of the Years Is Not Nil?
A holding corporation with investment income, a rental corporation and a corporation that paid or received a dividend are not nil. Those are handled by Gondaliya CPA Professional Corporation at gondaliyacpa.ca at $350.00 plus HST per year. We check before you pay. If we find it afterwards, we refund you in full.
