One finance function, many corporations
The organizing decision is to treat the whole group as a single finance function that happens to file several returns, because that is how everyone who judges you already sees it. Your lenders read the portfolio on a combined basis before pricing the next mortgage. CRA reads the intercompany activity as one fact pattern across related companies. Your family reads it as one pool of wealth. Only the bookkeeping, done entity by entity, often by different people at different times, treats the group as strangers, and that mismatch is where most of the expensive problems start.
Groups rarely arrive at multiple corporations by design. A first rental bought personally, the next in a company at the bank's suggestion, a numbered company per project because a partner wanted it that way, a holdco added somewhere along the line: the structure accretes, and the accounting inherits the archaeology. The result is familiar to anyone who works with property investors: no two companies on the same year-end, intercompany balances nobody can explain, and no single statement anywhere that says what the portfolio actually earns.
The question on this page usually arrives at a recognizable moment: the third or fourth property, the first outside partner, or the first time a lender asks for a personal net worth statement and the group's own records cannot produce one. Up to that point, the owner's memory has been the consolidation, and it worked. Past it, the portfolio's complexity outruns any one person's recall, decisions start being made on entity-level numbers that mislead, and the cost of the missing system starts compounding quietly in professional fees, lender friction and tax positions taken by default.
Getting this right is not about more bookkeeping; it is about running the group on three coordinated layers. The accounting layer keeps each entity's books clean and its intercompany positions reconciled. The cash flow layer consolidates, showing what the portfolio generates after every mortgage payment and where the next acquisition's equity will come from. The tax layer plans across the group, HST, capital cost allowance, refundable tax and the eventual exits, instead of treating each return as its own event. The rest of this page takes the layers in order.
A note on scope: this page is about how the pieces should work together in a multi-entity group. The service side, monthly books, rent rolls and filings for an investor's portfolio, is covered on our real estate investor accounting page, and the two are meant to be read from exactly where you are standing.
The entity map sets the rules the accounting must follow
Before any ledger entry is right or wrong, someone has to be able to draw the group on one page: every company, who owns its shares, which properties it holds, where each mortgage sits, and who has guaranteed what. That map is the constitution of the accounting, because it decides which company earns which rent, who may pay which expense, and what has to happen on paper when money moves. Groups that cannot produce the map produce, instead, a slow blur of entries in whichever company had cash that month, and unwinding a few years of that costs more than a decade of doing it properly. Drawing the map is always the first hour of work on a new portfolio, whoever does it.
The map also encodes decisions that deserve to have been made deliberately. Whether a property belongs in a corporation at all, given that corporate rental income enjoys no small-business rate, is a real question with a real answer per property, covered on should rental properties be held personally or in a corporation. Moving an existing property into or between companies is possible on a tax-deferred basis under the right elections, see transferring rental property to a corporation tax-deferred, but the mortgage complicates everything: debt above the property's tax cost can break the deferral, lender consent is required, and Ontario land transfer tax has no general exception for related-company transfers. The traps are collected on the tax risks of transferring mortgaged property to a corporation.
Separate corporations per property or per project remain common for good reasons, lenders like ring-fenced security, liability stays contained, and outside partners can hold one project without holding the portfolio. The cost is real too: every additional company is another return, another minute book, another set of intercompany relationships to maintain. The map is where that trade-off gets managed, and the honest rule is that a company should exist because something, a lender, a partner, a liability, requires it, not because incorporation had momentum that year.
The map's least glamorous column, guarantees and cross-collateralization, is the one that saves you at a bad moment. Personal guarantees accumulate deal by deal and are rarely revisited; properties end up securing each other's mortgages through general security agreements nobody rereads; and the group's true exposure to any one building's failure is larger than any single loan document admits. Mapping it once, then negotiating releases as loans season and values grow, is cheap insurance, and it is the kind of housekeeping that only happens when someone is looking at the whole group on one page.
Where partners or family members own pieces of some entities and not others, the map matters twice, because every intercompany decision now moves value between people, not just between companies. Management fees, loan terms and which entity gets the next deal stop being bookkeeping and become governance, and the paper standard rises accordingly.
Intercompany transactions are where bookkeeping becomes tax
Money moves constantly inside a property group, and every movement needs a name, paper to match, and both sides recorded in the same period. A transfer with no name eventually gets one assigned, by an auditor, a lender or a court, and the assigned name is rarely the cheap one. The recurring flows are few and worth doing properly:
- Management fees, where one company runs the portfolio and charges the others. The fee must reflect services actually provided at a defensible rate, be invoiced, and carry HST where it applies, because fees between commonly-owned companies are still taxable supplies unless a specific election is in place.
- Intercompany loans, when one property's surplus funds another's renovation or closing. Documented terms, a running balance both companies agree on, and interest where the tax results depend on it; an undocumented balance that grows for years is a reassessment waiting for a reason.
- Rent between related companies, when an operating business pays rent to a related property company. Market rate, under a written lease, consistently applied, both because the deduction depends on it and because a lender will read the lease before crediting the income.
- Shareholder flows, the owner's own draws, contributions and personal use. These belong in loan accounts reconciled monthly, since a shareholder debit balance left uncorrected can convert into personal income under rules with little sympathy.
The discipline that keeps all of this safe is boring and completely effective: a monthly close where every intercompany balance is confirmed by both entities, differences chased while they are small, and the paper, invoices, leases, notes, resolutions, filed as it happens rather than reconstructed for an audit. Groups that do this pass CRA reviews and lender diligence as a matter of routine; groups that do not fund those reviews out of professional fees and settlements.
Filing season is where the intercompany discipline gets tested, because the group's corporate returns have to tell one consistent story. A management fee deducted in one company must appear as income in another, in the matching period; interest expensed on an intercompany note must be interest income somewhere; and the companies are associated for tax purposes, which affects how certain limits and rates apply across the group and requires schedules that agree with each other. Returns prepared entity by entity, by preparers who never see the whole map, drift apart in exactly these places, and reconciling them after a CRA query costs multiples of preparing them together.
Year-ends deserve one sentence here: aligning the group on a single fiscal date is not mandatory, but it makes the monthly close, the consolidation and the intercompany confirmations dramatically simpler, and unless a specific reason argues otherwise, new entities should be born onto the group's date.
The reporting pack: entity statements plus one consolidated view
The group needs one reporting pack, produced on a rhythm, with three levels in it, and nothing about a portfolio can be decided sensibly without all three. Level one is per-property: rent actually collected, vacancies, operating costs and the property's net operating income, the number every appraisal and refinancing will be built on. Level two is per-entity: the statements each corporation files and shows its own lender. Level three is the consolidation, with intercompany flows eliminated: what the portfolio as a whole earns, what it keeps after every mortgage payment, and what is genuinely available for distributions or the next deposit.
The consolidated cash flow line deserves its status as the number the owner watches, because entity-level statements are structurally misleading in a group. One company can show handsome profit while its cash is trapped as an undocumented loan to a sibling; another can show a loss while sitting on the group's only liquidity. Refinancing proceeds look like income to a casual reading and are nothing of the kind. Only the consolidation, with the internal noise removed, answers the questions that matter: can the group carry its debt, fund its capital spending and still pay the family, and how much acquisition capacity is real rather than apparent.
The pack has an external audience too. Lenders with portfolio exposure increasingly ask for group-level disclosure at annual review, a net worth statement, a schedule of properties with their debts and maturities, sometimes the consolidation itself, and producing it on request, from a pack that already exists, reads as competence and prices accordingly. The same schedule of maturities is your own early-warning system: staggered renewal dates, watched together, are a manageable calendar, while the same dates discovered separately are a sequence of emergencies.
A forward view belongs in the pack as well, because property cash flow is lumpy in ways operating businesses are not. Each building carries a capital plan, the roof, the boiler, the unit turnovers, whose timing is roughly knowable, and the group carries a renewal calendar whose rate resets can move the whole portfolio's coverage. A rolling forecast that layers the capital plan and the debt calendar over the operating run-rate turns both from shocks into line items, and it is the difference between choosing which property funds the next reserve call and discovering that none of them can this quarter.
Where third-party property managers run the buildings, their monthly statements are source documents, not books. Manager reports arrive on cash timing, net of fees, and in the manager's categories; they have to be reconciled into the entity ledgers, not pasted over them, or the year-end becomes an excavation. That reconciliation habit, and the rest of the manager-to-owner pipeline, is its own discipline, and it is where a surprising share of portfolio bookkeeping actually goes wrong.
HST and CCA run on different logic, and both need a written policy
HST in a property group is decided activity by activity, not company by company, and the mixed portfolio holds both statuses at once. Long-term residential rent is exempt: no HST charged, and none of the HST paid on that building's costs recoverable. Commercial rent is taxable: HST charged to tenants and input tax credits recovered on the costs. The awkward cases sit between, mixed-use buildings needing allocations, new construction facing self-assessment when it converts to residential rental, and intercompany fees that stay taxable regardless of what the underlying property does. The working map:
| Activity | HST treatment | What to track |
|---|---|---|
| Long-term residential rent | Exempt; no ITCs on related costs | Costs stay HST-inclusive; no registration needed for this activity alone |
| Commercial rent | Taxable; ITCs recoverable | Registration, collection on rents, ITC documentation |
| Mixed-use building | Split by use | A supportable allocation method, applied consistently |
| New build or substantial renovation for rental | Self-assessment at fair value when first rented residentially; rebates may offset | The valuation, the timing and the rebate filings |
| Sale of property | Depends on use and buyer status; commercial sales often close with the buyer self-assessing | Certificates and elections settled before closing, not at it |
| Intercompany management fees | Taxable unless a specific election applies | Invoices, HST collected and remitted, or the election documented |
Capital cost allowance is the other system, and it is a choice each year, not an automatic entry. Buildings generally depreciate at 4% declining balance, CCA on a rental property generally cannot create or enlarge a rental loss, subject to exceptions for corporations whose principal business is real estate, and every dollar claimed is a dollar of potential recapture, taxed as income, when the property sells. Claiming maximum CCA is right for a long-hold property and wrong for one being groomed for sale; the decision belongs in the tax plan, per property, per year, with the recapture exposure tracked so a future sale's tax bill is a number, not a surprise.
Underneath the annual CCA decision sits a per-property record that only stays accurate if someone keeps it: the adjusted cost base, purchase price, closing costs, and every genuinely capital improvement since, alongside the repairs that were properly expensed. The capital-versus-repair line is one of CRA's favourite questions in real estate, and the answer is documentation contemporaneous with the work, not recollection at audit. The same record is what makes the tax on an eventual sale computable in advance, and it is the file most often missing when a portfolio changes accountants.
Both systems reward the same thing: a written policy, which building sits where, how mixed costs are allocated, what CCA posture each property takes, applied consistently and revisited annually. Improvisation at filing time is how a portfolio ends up with positions no one can explain three years later.
Tax planning across the group, and the facts that change it
The starting truth of corporate real estate taxation is that rental profit is investment income: taxed at roughly 50% in an Ontario corporation, with a large refundable slice that only comes back when taxable dividends are paid out. There is no small-business rate to protect, the specified-investment-business rules see to that unless the group genuinely employs more than five full-time people in the activity, so the planning centres on the refund mechanics, on which entities should hold cash, and on scheduling dividends so refundable balances do not sit sterile. Capital gains on sales add their own account: the untaxed half credits the capital dividend account, and paying it out tax-free before losses or missteps erode it is a discipline with a deadline no one announces.
Financing is tax planning's twin across a portfolio, because interest is usually the group's largest deduction and debt placement is a choice. Interest deductibility follows what borrowed money was used for, not which building secures the loan, so refinancing one property to fund another, or to fund distributions, changes the tax result and has to be traced properly. Renewals, meanwhile, are the moment the reporting pack pays for itself: a group that walks into a refinancing with clean entity statements, a current consolidation and a reconciled intercompany schedule gets underwritten on its numbers, and one that cannot produce them gets underwritten on the lender's caution.
Getting money to the family is its own scheduling problem in a structure where every dollar sits behind a corporate wall. The toolkit is ordinary, salary where there is real work and RRSP room to build, dividends timed to release refundable tax, repayment of whatever the owners have genuinely lent the companies, but the sequencing across entities is not: which company pays, in which year, decides how much refundable tax comes back and what personal rate applies. A group that plans distributions annually, as one exercise, routinely funds the same lifestyle at a lower total cost than one where each company improvises its own payout.
The horizon questions belong in the same plan, because a property group is usually the family's largest estate asset and the least liquid. Which properties are hold-forever and which are trading stock shapes everything from CCA posture to entity design; capital gains at death land on shares that no one can sell a floor of; and an estate freeze at the right moment caps the founder's tax exposure while the next generation's growth accrues in their own hands. This is where a business estate planning CPA in Ontario earns the title: the corporate structure, the leases and the wills have to describe the same plan, and in most groups we meet, they have never been read together.
What changes the answer, portfolio to portfolio, is a short list: how many entities and whether partners share any of them; the residential, commercial and development mix, which drives the HST posture; whether the strategy is hold, trade or build, which drives CCA and even whether gains are capital at all; how much of the group's cash flow the family actually needs; the refinancing calendar; and how close succession really is. Two portfolios of identical size can need opposite plans across every one of those dimensions, which is why the planning starts with the map and the pack rather than with someone else's structure, and why generic advice about holding companies and rental corporations transfers so poorly between owners.
The shape of the work follows from everything above. A property group's finance function is a monthly rhythm, the close, the intercompany confirmations, the pack, the HST filings, punctuated by planned events: renewals, acquisitions, sales, and eventually the freeze. That rhythm is exactly what our Ongoing Financial Partnership provides, with the one-time restructurings scoped separately as projects. Either conversation starts with the same free 15-minute discovery call, and the first deliverable is usually the one-page map this page kept coming back to, drawn from your minute books, mortgage statements and last filed returns rather than from memory.
