Reporting Rental Income in Quebec: A Plex Owner's Guide to Forms TP-128 and T776

Reporting rental income in Quebec runs through two forms that every plex owner must file each year: the TP-128 with Revenu Québec and the T776 with the Canada Revenue Agency. This is the annual reporting of rental income — not to be confused with the capital gain, which only arises on sale. This guide explains, step by step, how to report your gross income, which expenses to deduct, and how to allocate the co-ownership share if you own your duplex or triplex with others. The goal: file accurate forms, lawfully reduce your tax, and avoid the mistakes that draw an audit.

TP-128 and T776: Two Forms, One Logic

In Quebec, an individual who earns income from renting a property must file two parallel statements. Form TP-128 "Income and Expenses Respecting the Rental of Immovable Property" accompanies your provincial return to Revenu Québec. Form T776 "Statement of Real Estate Rentals" accompanies your federal return to the Canada Revenue Agency. Both follow the same logic: gross income, minus expenses, equals net rental income (or loss).

That net income is then added to your taxable income and taxed at your marginal rate — like a salary. So it has nothing to do with the capital gain on the sale of your plex, which follows completely different rules and only happens once, when you dispose of the property.

Step 1 — Calculate Gross Rental Income

Gross rental income is the starting point of both forms. It groups together all amounts received from your tenants during the calendar year, before any deduction. For a plex, that includes far more than the base rent.

• Monthly rent collected for each unit;
• Parking, laundry, storage income charged separately;
• Last-month rent amounts when they are actually applied as rent;
• Any amount received for a service tied to the rental (charged snow removal, furnished unit, etc.).

Most small owners report on the cash method: you record the rents actually collected during the year, not those merely billed. Unpaid rent is therefore not reported as income until it is received — but it does not automatically become an expense either. To gauge the impact of a vacant unit or overdue rent on overall profitability, our guide to calculating a multiplex's yield can help you place these figures in the bigger picture.

Step 2 — Deduct the Right Expenses

You can deduct the current expenses incurred to earn your rental income. This is where most of your tax savings — but also the main risk of error — plays out. The table below sums up the most common items for a plex.

The trickiest distinction is between a current expense (repairing, restoring to original condition — deductible immediately) and a capital expense (improving, extending useful life, replacing a whole asset — depreciable only). Repainting a unit is current; redoing the entire roof is capital. When in doubt, the position of Revenu Québec and the CRA rests on the lasting nature of the improvement.

Step 3 — Allocate the Co-Ownership Share and Owner-Occupied Unit

If you own your plex with others — a spouse, a parent or a partner — each co-owner reports their share of income and expenses based on their actual percentage of ownership. A couple owning the property equally will each report 50% of the net income on their own return, provincially and federally. That percentage must reflect true ownership on title; you cannot freely choose the split to minimize tax.

Another common situation on the North Shore: the owner-occupant who lives in one unit of their duplex or triplex. In that case, only the rented portion generates rental income. Common expenses (taxes, insurance, central heating) must be split between the personal and rental portions, generally in proportion to floor area or number of units.

CCA and the Link to a Sale

For capital expenses (roof, heating system, addition), you don't deduct the amount all at once: you can claim the capital cost allowance (CCA), which spreads the expense over several years according to the asset's class. CCA is optional. Key rule: it can never create or increase a rental loss. If your building is already in a loss before CCA, you cannot claim it that year.

Above all, claiming CCA has a consequence on sale: it can trigger a recapture of depreciation, taxed as ordinary income in the year of the sale. It's a long-term trade-off, explained in our dedicated article on the recapture of CCA when selling your plex. Annual reporting and sale taxation are therefore linked, but remain two distinct mechanisms.

Common Mistakes to Avoid

• Deducting mortgage principal repayment. Only interest is deductible, never the principal portion of your payments.
• Confusing repair and improvement. Running a major renovation through as a current expense to deduct it all at once is a classic error.
• Forgetting ancillary income. Parking, laundry and storage are taxable rental income.
• Misallocating the ownership share. Each co-owner reports based on actual ownership, provincially and federally.
• Creating a loss with CCA. CCA cannot generate a rental loss — the CRA and Revenu Québec will disallow it.
• Not keeping documents. Keep receipts, leases and statements for at least six years in case of audit.

If your building keeps stacking up losses year after year and reporting becomes a burden, it may be time to reassess your position. ImmoMulti buys multi-unit properties directly on the North Shore, with no broker and no commission — an avenue worth considering when the taxation of your building weighs more than the return it delivers.

The Plex Owner's Tax Calendar: Dates, Penalties and Instalments

Filing the TP-128 and T776 only pays off if you meet the deadlines. For an individual who owns a plex, the tax calendar is simple to grasp but costly to ignore: every week of delay chips away at your net return through penalties and interest. Here is how to structure your year so you are never caught off guard.

The deadline: April 30 for almost everyone

For an individual, the income tax return — provincial and federal — and payment of any tax balance must reach the authorities no later than April 30 of the year following the tax year. If April 30 falls on a Saturday or Sunday, the deadline shifts to the next business day. Rental income is property income, not business income: unlike the self-employed (who get until June 15 to file, but must still pay by April 30), the plex owner gets no extension. Remember a single date: April 30.

An important nuance: the filing date and the payment date both fall on April 30, but they trigger two separate sanctions. Filing late triggers a penalty; paying late triggers interest. Even if you lack the cash to settle your balance, file on time: you will avoid the late-filing penalty, often far heavier than the interest.

Late penalties, in figures

Revenu Québec and the CRA apply the same logic. The late-filing penalty equals 5% of the unpaid balance at the deadline, plus 1% of the balance for each full month late, up to a maximum of 12 months. A prolonged delay can therefore cost up to 17% of the balance owing — and that at each level, provincial and federal, which calculate their penalty separately.

Sources: Revenu Québec — Late penalties and CRA — Late-filing penalty.

Instalments: when tax is paid in advance

If your plex generates meaningful net income and no tax is withheld at source, you may become subject to instalment payments — quarterly prepayments of tax (March 15, June 15, September 15, December 15). In Quebec, the obligation arises when your net tax owing exceeds $1,800 for the current year and for one of the two preceding years. Federally, the general threshold is $3,000 (reduced to $1,800 for Quebec residents, because of the abatement).

In concrete terms: an owner whose triplex yields $12,000 of net income with no withholding at source will quickly cross these thresholds. Revenu Québec then mails form TPZ-1026.A in February and August with the suggested amounts. Ignoring these payments exposes you to instalment interest — an avoidable tax cost that directly penalizes your return.

Every Deductible Expense Under the Microscope

The Step 2 table gives the overview; this section drills into the detail, item by item, because this is where the most money is won — or lost. On a North Shore plex, the difference between a sloppy return and a careful one can amount to several thousand dollars of tax each year.

Mortgage interest: the most misunderstood item

On a mortgage payment, only the interest portion is deductible; the principal repayment never is. Early in the amortization, the interest share is high, which boosts the deduction; over the years it shrinks as you repay principal. Your lender issues an annual interest statement each winter: that is the figure to report. Certain ancillary financing costs (mortgage brokerage fees, legal fees for the loan deed, lender-required appraisal fees) are also deductible, but amortized over five years rather than deducted all at once.

Taxes, insurance and energy

The municipal and school taxes on the rental portion are fully deductible. So is the insurance premium on the rental building — remember to deduct only the portion prepaid for the year in question. Electricity and heating are deductible only if you pay them: in a triplex where each unit has its own meter in the tenant's name, there is nothing to deduct there; in a building with central heating paid by the owner, the whole bill (rental portion) is.

Maintenance, repairs… and the capital red line

This is the king of distinctions. A current expense restores the property to its original condition and is deducted immediately: patching and repainting, fixing a leak, replacing a few torn shingles, clearing a drain. A capital expense improves, extends useful life or replaces a whole asset: a fully redone roof, new windows throughout the building, an entirely renovated kitchen. The first reduces your tax this year; the second must go through capital cost allowance.

The overlooked items that boost the deduction

• Professional fees: accountant to prepare your rental schedules, legal fees tied to lease management or rent collection.
• Management and advertising fees: ads to find a tenant, a manager's fees, property-management software.
• Landscaping, snow removal, caretaking: services rendered to the rental building.
• Reasonable office and travel costs to collect rents or supervise work — subject to strict rules.
• Condo fees if a rented unit is a divided co-ownership.

Conversely, never try to deduct the value of your own labour: if you repaint a unit yourself, only the materials are deductible, never your time. It is a common mistake among hands-on owners.

CCA in Depth: Class 1, Class 8 and the Half-Year Rule

Capital cost allowance (CCA) deserves its own section, because it is at once the plex owner's most powerful and most booby-trapped tool. Well used, it turns a capital expense into spread-out tax savings; badly used, it sets up a hefty bill on resale.

The building: Class 1, a 4% rate

Most buildings acquired after 1987 fall into Class 1, depreciated at a declining-balance rate of 4% per year. "Declining balance" means the 4% applies each year to the remaining balance (the undepreciated portion of the capital cost), not to the original cost. CCA therefore melts away gradually, year after year. Key point: land is never depreciable. You must split your purchase price between the building (depreciable) and the land (non-depreciable), generally according to the municipal assessment roll.

Furniture and appliances: Class 8, a 20% rate

Assets that are not part of the structure — refrigerators, stoves, supplied washers and dryers, blinds, furniture in a furnished unit — generally fall into Class 8, depreciated at 20%. The higher rate reflects their shorter useful life. For a plex rented furnished or where you supply the appliances, this class becomes a meaningful deduction lever.

The half-year rule in the year of acquisition

In the year you add an asset to a class, the half-year rule (50% rule) generally limits you to half the normal CCA on that net addition. A Class 1 building acquired this year will therefore allow only 2% (half of 4%) in the first year, then 4% of the balance in later years. Special investment-incentive rules have modulated this mechanism in recent years: for the exact treatment of your year of acquisition, confirm with a tax specialist.

Sources: CRA — Rental classes of depreciable property and CRA — Guide T4036, Rental Income.

The golden rule: never a loss created by CCA

Let us say it again, because it is the most defining constraint: CCA cannot create or increase a rental loss. If, before CCA, your building already shows a loss, you cannot claim CCA that year. If, before CCA, your net income is $3,000, you can claim at most $3,000 of CCA, bringing net income to zero — never below. This "unused" CCA stays available in the class balance for future years. That is what makes CCA a tax-deferral tool, not an erasure.

A Full Worked Example: A North Shore Triplex

Nothing clarifies the mechanics of the TP-128 and T776 better than a concrete case. Take a fictional triplex in Sainte-Thérèse, owned equally by a couple. The figures below are illustrative — they show the path of the calculation, not your actual situation.

Step A — Gross rental income

The three units rent for $1,250, $1,100 and $1,350 per month. One tenant pays $60 a month for a parking spot, and the shared laundry brings in about $480 in the year.

• Rents: ($1,250 + $1,100 + $1,350) × 12 = $44,400
• Parking: $60 × 12 = $720
• Laundry: $480
• Total gross income: $45,600

Step B — Eligible expenses

Step C — Net income and the ownership share

Gross income ($45,600) minus expenses ($33,100) = net rental income of $12,500. Since the couple owns the building 50/50, each spouse reports $6,250 of net rental income, on both their TP-128 and their T776. That amount is added to their taxable income and taxed at their respective marginal rate.

This example shows why two triplexes with identical gross income can produce very different tax bills: it all comes down to the rigour of the expenses and the choice, or not, to claim CCA. To place your own building in this picture, our guide to calculating a multiplex's yield breaks down the same logic on the profitability side.

GST/QST, Deductible Losses and Reasonable Expectation of Profit

Three questions come up constantly among plex owners: do I charge tax on the rent? what do I do with a loss year? and how far can losses accumulate? Here is the essential, sourced.

Long-term residential rental is GST/QST-exempt

Good news for simplicity: renting a residential unit for a period of one month or more is an exempt supply. You therefore do not charge GST or QST on your tenants' rent, and you have nothing to collect or remit. The flip side: because your rents are exempt, you cannot recover, through input tax credits (ITCs/ITRs), the GST/QST you pay on your expenses (renovations, fees, etc.). That tax paid simply becomes part of the deductible or depreciable cost.

Do not confuse this with short-term accommodation (tourist-style rentals under 31 days), which follows entirely different tax rules. A new rental building or one that has undergone major renovations may also open the door to a partial GST/QST rebate, subject to value conditions — a file to build with a professional.

A rental loss can reduce your other income

If your eligible expenses exceed your gross income, you report a net rental loss. Unlike a capital loss, this rental loss (a loss of property income) can reduce your other taxable income for the same year: salary, investment income, etc. It therefore lowers the household's overall tax in the year it occurs. Crucial reminder: CCA must never have been used to create or deepen this loss.

The reasonable-expectation-of-profit test

The authorities accept a loss as long as it flows from a genuine activity carried on for profit. A structurally loss-making building, year after year, with no realistic prospect of ever generating net income, may have its losses challenged if the activity looks more like personal use or a business with no hope of profitability. A plex rented at market rate to third parties generally passes the test easily; it is the chronic accumulation of losses, or below-market renting to a relative, that draws questions.

Owner-Occupant: Allocation, Principal Residence and the CCA Trap

The duplex or triplex lived in by its owner is a North Shore classic: you live in one unit, you rent the others. Tax-wise, this setup blends two worlds — rental income and principal residence — and it is precisely at their border that the costliest mistakes hide.

Allocating income and expenses on a prorated basis

Only the rented units generate rental income. The building's common expenses — taxes, insurance, central heating, structural maintenance — must be split between your personal portion and the rental portion. Two allocation methods are accepted, provided they are reasonable and consistent:

• By number of units: in a triplex where you occupy one unit, about 2/3 (67%) of common expenses are rental.
• By floor area: if your unit occupies 40% of the living area, 60% of common expenses are rental. This method is preferable when units are very unequal in size.

Choose a method, document it, and keep it from year to year. Expenses specific to your own unit (your electricity, your personal repairs) are neither income nor a deductible expense.

The CCA trap on your occupied unit

Here is the most important warning of this section. Your personal unit normally benefits from the principal residence exemption, which shelters the gain on that portion when you sell. However, claiming CCA on the part you live in can be interpreted as a partial change of use and jeopardize that exemption for your unit. Many tax specialists therefore recommend that an owner-occupant not claim CCA in order to preserve the exemption on their residential portion. It is a delicate trade-off: consult a professional before ticking anything.

The border between residential and rental portions resurfaces when you sell: the gain then splits between an exempt portion (your residence) and a taxable portion (the rented units). Our article on the change of use between residence and rental details this mechanism.

Bookkeeping: Preparing Your Forms Without Stress

An accurate TP-128 and T776 are not improvised in April: they are built throughout the year. Careful bookkeeping turns the annual chore into a simple transfer of figures — and protects you in case of an audit.

One account and one ledger per property

Ideally, each property has its own bank account: all rents come in, all expenses go out. The year-end reconciliation then becomes obvious. Failing that, keep a ledger — a simple spreadsheet will do — with, month by month, one column per item: rents collected, parking, laundry, then taxes, insurance, interest, energy, maintenance, management. The sum of the columns gives you, at a glance, each box of the TP-128 and T776.

What to keep — and for how long

• Leases and rent-adjustment notices;
• Annual mortgage interest statements;
• Municipal and school tax bills;
• Maintenance, repair and renovation invoices (invaluable for distinguishing current from capital);
• Proof of rents collected (deposits, receipts);
• Insurance policies and proof of payment.

Revenu Québec and the CRA recommend keeping these documents for at least six years after the end of the tax year in question. Scanned documents are accepted, provided they are legible and complete. This well-kept file serves twice: it makes your annual return easier, and it will document the adjusted cost base of the building the day you sell.

Sources: CRA — Keeping records and Revenu Québec — Rental Income (line 136).

The signals that draw an audit

• A personal/rental allocation that changes each year for no reason.
• "Repairs" wildly out of proportion to the building's income.
• A rental loss that repeats year after year.
• Ancillary income (parking, laundry) systematically absent.
• CCA that, as if by chance, brings net income exactly to zero every year.

When the Return Becomes a Signal to Sell

Filing your forms is one thing; what they reveal is another. Year after year, the TP-128 and T776 paint a merciless health check of your plex. When certain figures keep coming back, they stop being an administrative chore and become a portfolio decision.

The tax signals of a building that weighs more than it earns

• Chronic net losses that eat into your other income instead of adding to your wealth.
• Mortgage interest that crushes net income, especially on renewal at a higher rate.
• Capital expenses piling up (roof, windows, structure) with no possible rent increase.
• CCA you no longer dare to claim, for fear of recapture on resale.

None of these signals alone commands a sale. But their combination, year after year, deserves a cold calculation: between tax on a loss-making building, rising upkeep and locked-in capital, is the building still funding your future, or draining your energy?

Selling without commission when taxation wins

If your returns tell, year after year, the same story of losses and heavy expenses, a direct sale may be the cleanest exit. ImmoMulti buys multi-unit properties directly across the whole North Shore, with no broker and no commission, with a firm price within 48 hours. You avoid marketing costs and you know your net upfront. To understand the taxation of the exit itself, see our guide on the capital gain on selling your plex in 2026 and on the recapture of CCA.
