Board members turn over every year or two, and the returns keep coming whether anyone remembers them or not. This guide is for boards, property managers and owners in Ontario. It covers why the corporation behind your building usually pays no income tax, what can change that, what it files with the CRA and the province, and what Ontario law requires of its reserve, its statements and its audit.
Key Takeaways
- The exemption in paragraph 149(1)(l) removes the tax, not the return, so a return goes in every year.
- A reserve above $200,000 trips the T1044 asset test on its own, and once the T1044 is required it stays required.
- Filing a nil corporate return late costs nothing under the usual penalty formula, but each missed T1044 can cost up to $2,500.
- Fees charged to residential owners carry no GST/HST; roof leases and commercial unit fees can.
- Buildings under 25 units can skip the audit only with every owner’s written consent, collected again for each annual general meeting.
How Condominium Corporations Qualify as Non-Profit Organizations (NPOs)
Condominium corporations in Canada are created under the laws of the provinces and territories; in Ontario, that law is the Condominium Act, 1998 (the Ontario Act). The archived bulletin IT-304R2 describes the result as a corporation without share capital whose members are the owners, set up to manage the property and its assets. Quebec’s Civil Code reaches the same place through divided co-ownership: publishing a declaration of co-ownership establishes a syndicate that manages the common portions for the co-owners.
Federal tax law then decides whether that body pays income tax. Paragraph 149(1)(l) of the Income Tax Act (ITA) covers a club, society or association that is not a charity, is organized and operated exclusively for a purpose other than profit, and makes no part of its income payable to, or available for the personal benefit of, a member.
The agency’s guide to the NPO return, T4117, says that although a factual determination must be made in each case, most residential condominium corporations qualify because they are usually operated for a purpose other than profit. While the status holds, the corporation is exempt from paying Part I income tax, and IT-304R2 adds that owners’ condominium fees and contributions in excess of the year’s spending are not income at all.
Ontario law fits that picture. Subsection 95(3) of the Ontario Act makes the reserve an asset of the corporation that cannot be distributed to owners except on termination, which, on our reading, sits comfortably with the rule that no income be available for members’ personal benefit.
What Puts the Exemption at Risk: Rental Income and Business Profits
IT-304R2 separates two types of income. Interest on operating or reserve money, rent and other incidental income is income of the corporation, which the exemption covers while the status holds. If it carries on a business, though, the bulletin says its profits must be included in income and it will not be considered an NPO. Where incidental income ends and a business begins is a question of fact.
In our work with boards, the income that causes trouble is rarely large: a rooftop antenna licence signed by an earlier board, parking leased to neighbours, or a guest suite offered to the public, still paying into the general account years later with nobody reviewing it. Before signing or renewing, ask whether the income is incidental to running the building, whether it recovers costs rather than earning a margin, and whether every dollar goes back into the property. Then record the answers in the minutes.
If the status is lost, interest, rent and other outside income become subject to Part I tax, and the building also loses its paper-filing option, as the next section explains. Our overview of the types of audits the agency conducts shows how a review can start, and our tax dispute representation team can respond for the board.
Canada Revenue Agency Filing Requirements: The Annual Return
Paragraph 150(1)(a) of the ITA requires a corporation resident in Canada to file a return of income no later than six months after the end of each taxation year, without notice or demand. For corporations, subsection 150(1.1) excepts only registered charities. IT-304R2 put it directly: paragraph 150(1)(a) requires all corporations, including condominium corporations, to file an income tax return each year, even when they owe no Part I tax.
On page 1, the claim goes at line 085: the agency’s T4012 guide tells an organization described in paragraph 149(1)(e) or (l) to tick box 1, and the return goes in under the business number on line 001. Most corporations have to file electronically, but section 205.1 of the Income Tax Regulations leaves out corporations that section 149 relieves from tax, so a qualifying corporation can still use paper. One that loses the exemption has to send its tax return electronically, and the agency charges a $1,000 penalty for non-compliance under subsection 162(7.2).
Ontario adds its own requirement to file returns. Under O. Reg. 377/17, an annual return goes to the Condominium Registrar by March 31, in practice through the Condominium Authority of Ontario (CAO), along with a turn-over return no later than 90 days after the turn-over meeting and a notice of change no later than 30 days after a change. Section 9.6 of the Ontario Act adds a late fee for any of them.
When the T1044 Information Return Is Required
Subsection 149(12) of the ITA adds a second federal return for an organization that relies on paragraph 149(1)(e) or (l). The return must be filed within 6 months after the end of each fiscal period, without notice or demand, if any one of three tests is met:
- Taxable dividends, interest, rentals and royalties received or receivable in the period total more than $10,000.
- Total assets at the end of the previous fiscal period, determined under generally accepted accounting principles, were more than $200,000.
- The organization had to file this return for any earlier fiscal period.
The third test makes the return permanent: once one year triggers it, every later year is caught, even after interest rates fall. T4117 says total assets are their book value under generally accepted accounting principles, so the reserve accounts count, and it directs the paper return to the T1044 Program at the Jonquière Tax Centre.
Example. A 140-unit building in Mississauga ends its fiscal year on December 31. At December 31, 2025, its balance sheet shows $1.9 million in reserve investments and $260,000 in its general account. Assume the reserve earns 3.5% during 2026. By our arithmetic, that is $66,500 of interest, more than six times the $10,000 test, and the prior year-end assets passed $200,000 more than ten times over. Either test alone makes a T1044 due for 2026, by June 30, 2027, and every year after that. Neither number creates a dollar of income tax.
Late Filing: Why a Missed T1044 Costs More Than a Missed Corporate Return
For the corporate return, subsection 162(1) charges 5% of the tax unpaid at the due date plus 1% of it for each complete month late, up to 12 months. When no tax is owing, that formula comes to zero. The T1044 falls under subsection 162(7) instead: the greater of $100 and $25 for each day the failure continues, up to 100 days, which T4117 states as a $100 minimum and a $2,500 maximum for each failure to file.
Example. A board discovers the T1044 was never filed for the last five years. By our arithmetic, if the agency assessed all five at the maximum, the penalties would total $12,500 against zero tax. The agency’s Voluntary Disclosures Program covers certain unfiled returns of this type, with Form T1135 as its example, but only for an application made before an audit or investigation starts, so ask whether a catch-up qualifies before you file the missing years. Where tax is actually owed, the rules in our guide to interest and penalties apply too.
Tax Implications of Reserve Fund Investment Income
Owners’ contributions are not income, but the interest earned on them is. IT-304R2 says a residential condominium corporation that qualifies under paragraph 149(1)(l) pays no Part I tax, and the provision that taxes the investment income of certain paragraph (l) bodies is aimed elsewhere.
That provision, subsection 149(5), taxes the property income and certain capital gains of an organization through a deemed trust, after a $2,000 deduction, but only where the organization’s main purpose is to provide dining, recreational or sporting facilities for its members. A residential building’s corporation exists to manage property, as IT-304R2 describes it, so on our reading the rule should not reach it on ordinary facts. A building whose amenities start operating like a members’ club deserves a second look.
Ontario law adds its own rule. Subsection 93(7) says income earned from investing reserve money forms part of the fund, so it cannot pay for the operating budget. It still counts toward the $10,000 T1044 test, which looks at interest received or receivable, not at where it is spent.
Section 115 regulates where the money sits: separate general and reserve accounts at a Schedule I or II bank, a trust or loan corporation, or a credit union in Ontario, with investments limited to eligible securities such as instruments issued or guaranteed by the Government of Canada or a province. General account money may go only into securities convertible to cash within 90 days of the board’s request, and before investing reserve money the board must develop an investment plan based on its most recent study.
Reporting Requirements: Reserve Fund Studies and Financial Statements
Section 93 requires one or more reserves, used solely for major repair and replacement of the common elements and assets and funded through owners’ common expense contributions. Section 94 requires periodic studies of whether the balance and contributions are adequate. A new corporation completes its first study within the year after registration, and O. Reg. 48/01 then requires another within every three years; a study without a site inspection must be followed by one with a site inspection or by a new comprehensive study.
Within 120 days of receiving a study, the board proposes a funding plan. Within 15 more days it sends owners a summary and the auditor copies, and it implements the plan once another 30 days have passed.
Subsection 66(2) requires a balance sheet, a statement of general operations, a statement of changes in financial position, a statement of operations for the reserve, prescribed reserve information and the total remuneration of directors and of officers, all prepared under generally accepted accounting principles. Section 16 of O. Reg. 48/01 adds two comparisons: reserve contributions collected, and reserve spending, each against the board’s funding plan. Two directors sign the approved balance sheet, a copy goes out with the notice of the annual general meeting, and the reserve balance on it is part of the total the $200,000 T1044 test reads.
When a Condominium Corporation Needs an Audit
Subsection 60(2) requires the owners to appoint an auditor at each annual general meeting, and section 67 requires a yearly examination and report on the statements, including whether the reserve figures do not fairly present the reserve studies the auditor received. Under section 61, a director, officer or employee, or the manager who provides management services to the corporation, cannot be its auditor.
Smaller condominiums may skip the audit only under subsection 60(5), when all three conditions hold: the turn-over meeting has been held, there are fewer than 25 units, and, as of the date of the meeting, all the owners consent in writing to dispense with the audit until the next annual general meeting. Under subsection 60(6), an owner 30 days or more in arrears on common expense contributions cannot consent until the arrears are paid, so one overdue account can bring the audit back for the year.
What the audit covers, and why a board might keep one even when it could waive it, is the subject of our guide to the condo audit in Ontario. The audit and the tax returns are often separate engagements, and in our experience the gap between them is where the T1044 goes missing: the manager assumes the auditor files it, and the auditor was never engaged to. Name the person who owns each filing in the minutes.
GST/HST on Fees for Residential and Commercial Condominium Units
Section 13 of Part I of Schedule V to the Excise Tax Act (ETA) places supplies by the corporation to the owner or lessee of a residential unit, where they relate to the occupancy or use of the unit, among the supplies that carry no GST/HST. GST/HST Memorandum 19.2.2 draws the consequence: residential condominium corporations are treated much like residential landlords and generally cannot claim input tax credits (ITCs) on related purchases, a result our explainer on how exemptions differ from zero-rating walks through. The memorandum also treats roof space rented to a cellular phone company as unrelated to a residential unit, so a registered corporation must charge GST/HST on that rent.
Commercial units fall outside section 13, which speaks only of residential units. On our reading, a commercial owner’s common expense contributions are taxable supplies that count, with outside rent, toward the small supplier limit. If the corporation meets the ETA’s NPO definition, section 123 makes it a public service body, and section 148 sets its limit at $50,000 rather than $30,000, tested in a single calendar quarter and over the four quarters before it. Beyond that limit, section 240 requires registration, covered in our guide to HST for small business, and the corporation charges 13% HST in Ontario, the harmonized form of the goods and services tax (GST), on those supplies.
Example. A mixed-use building in Toronto has 180 residential units and 6 ground-floor commercial units whose owners each pay $1,100 a month in common expenses. By our arithmetic, the commercial fees alone come to $19,800 a quarter and $79,200 over four quarters, well above $50,000, so on our reading the building cannot stay a small supplier. Once registered, it adds 13% HST, $143 a month, to each commercial owner’s fees, while the 180 residential owners’ fees stay free of GST/HST.
Common Mistakes Condo Boards Make With Tax Obligations
- Treating the annual return as optional because the building owes no tax.
- Filing the corporate return but not the T1044 after the reserve pushed total assets past $200,000.
- Dropping the T1044 when interest rates fall, even though the third test keeps it running.
- Assuming the audit engagement covers the tax returns when the engagement letter does not say so.
- Signing a roof, parking or amenity agreement with outsiders without asking what it does to the NPO status.
- Charging HST on residential fees, or not registering once commercial fees and outside rent pass the $50,000 limit.
- Losing copies of past returns and notices when the condo management company changes.
Action Checklist: Filing Obligations for Condominium Corporations
- Diarize the date six months after year-end for both federal returns.
- Test the prior year-end balance sheet against $200,000, and the year’s interest, rentals, royalties and dividends against $10,000.
- Ask your accountant to confirm the paragraph 149(1)(l) claim at line 085 and to note the facts behind it.
- Minute who files each return: the manager, the auditor or a separate adviser.
- Review every agreement that brings in outside money before it is signed or renewed.
- Total commercial unit fees and outside rent each quarter against the $50,000 small supplier limit.
- Collect written audit-waiver consents from every owner before each annual general meeting, if the building qualifies.
- Keep the information required for all three returns, with each notice of assessment, in one year-end file that every condo board can hand to the next.
Frequently Asked Questions
Do condo corporations file tax returns in Ontario?
Yes. Every condominium corporation resident in Canada has to file a return of income each year under paragraph 150(1)(a) of the ITA, even when no tax is owed. It adds the T1044 when a subsection 149(12) test is met, and an annual return with the CAO by March 31.
Who is not required to file a corporate tax return?
The Canada Revenue Agency says all resident corporations, except tax-exempt Crown corporations, Hutterite colonies and registered charities, have to file a T2 return for every tax year, even if there is no tax payable. A condo corporation is none of these, so it is required to file each year.
What is the CRA 3-year rule?
It is the normal reassessment period in subsection 152(3.1) of the ITA: generally three years after the earlier of the original notice of assessment and the original notification that no tax is payable, or four years for a corporation other than a Canadian-controlled private corporation. Which applies to a particular building turns on its classification, so confirm it with your accountant; our guide to statute-barred tax years covers the exceptions.
Can you claim condo fees on your tax return?
Not as a unit owner living in the suite: fees on your own home are a personal cost, and paragraph 18(1)(h) of the ITA bars deducting personal or living expenses from business or property income. If you rent the unit out, the agency says you can deduct condominium fees that represent your share of the upkeep, repairs, maintenance and other current expenses of the common property.
Are condo special assessments tax deductible?
Not on your own home. For a rented unit, the archived bulletin IT-304R2 said the reserve portion of fees and special levies for common property repairs cannot be deducted or capitalized until the corporation lays the money out, and the nature of the work then decides whether the cost is current or capital.
What penalties apply to a late tax filing by a condo corporation?
A late T1044 costs the greater of $100 and $25 a day for up to 100 days, so up to $2,500 a return. A late corporate return costs 5% of unpaid tax plus 1% for each complete month, to 12 months, which is nothing when no tax is owed. Returns delivered late to the CAO also attract a fee under the Ontario Act.
Does the corporation pay tax on interest its reserve earns?
Not while it qualifies under paragraph 149(1)(l). The interest still counts toward the $10,000 test for the T1044, and Ontario law requires it to stay in the reserve.
Can a condo corporation get back the GST/HST it pays?
Generally not on the costs of serving residential owners, because Memorandum 19.2.2 says such corporations generally cannot claim input tax credits on those purchases. A registered corporation can claim credits to the extent its purchases are used to make supplies it charges GST/HST on, such as commercial unit fees or roof rent.
The Bottom Line
The tax position is usually simple; the filing calendar is not.
- File the federal return every year, six months after year-end, even at nil tax.
- Check the three T1044 tests each year, and keep filing once any one has applied.
- Vet outside income against the NPO conditions before signing, not after.
- Keep residential fees free of GST/HST, and register once commercial fees and outside rent pass $50,000.
- Follow the Ontario Act on the reserve, the statements and the audit, and renew any audit waiver every year.
Every building mixes these obligations differently, depending on its units, its reserve and its outside income, so treat this as orientation rather than a ruling on yours. Our corporate tax team can take over the federal returns, our assurance team handles the audit Ontario law requires, and you can book a review of your board’s returns before the next year-end.
