Incorporating an excavation business: financing iron, and where the iron should live

The corporation is how you afford the iron

Loan principal is repaid with after-tax dollars, and that single fact decides where excavation equipment debt belongs. Inside an Ontario corporation, profit used to pay down a machine is taxed at about 12.2% up to the $500,000 small business limit; the same repayment funded personally costs you dollars taxed at up to 53.5%. Across a fleet financed over five to seven years, the corporation is often the difference between growing the iron and servicing it forever.

The HST side matters just as much for cash flow. A registered corporation recovers the tax on a mid-size excavator as a five-figure input tax credit on its next return — money a non-registered or sloppy setup leaves stranded. Dealers finance new corporations routinely; expect personal guarantees in the early years and treat retiring them as a milestone the company's own statements eventually earn.

Opco or holdco: where the machines should sit

Excavation claims are the reason this question exists. A struck gas line, a trench collapse, an undermined foundation next door — claims like these target the operating company, and every paid-down machine sitting in it is exposed. The mature structure holds the iron in a holding company that leases it to the opco at market rates, so the fleet stands behind the corporate wall rather than inside the ring.

The elections that make the split workable

Two filings turn the holdco from theory into a working structure. The GST/HST section 156 election (form RC4616) lets closely related, exclusively commercial corporations treat the equipment lease as made for nil consideration — no HST invoiced between your own companies, no cash flow lag waiting on ITCs. And machines already owned by the opco move up under a section 85 rollover so the transfer itself triggers no income tax; without it, shifting an appreciated or heavily depreciated machine can create recapture in the very year you were trying to plan around.

Respect the paperwork the structure depends on. The lease is written, priced like a third-party rental, and actually invoiced monthly; the election is filed, not assumed; and the shared small business limit is planned so leasing income and operating profit together stay inside it.

Lenders come before structure

Talk to your lender before you move a single machine — financed equipment almost always carries clauses that make an unapproved transfer a default. Most lenders want the borrowing entity to own the collateral, so the practical pattern is patience: machines under loan stay in the company that financed them, and the holdco takes ownership as they pay out or buys the next machine itself where the lender agrees. Watch cross-collateralization too — blanket security that ties the whole fleet to one facility quietly defeats the purpose of separating it. A conversation with the finance arm before the reorganization usually finds a workable path; a transfer they discover afterward rarely does.

CCA, US auctions, and day one

Excavators, dozers, and loaders land in Class 38 at 30% declining balance, while tandem dump trucks rated over 11,788 kg typically reach Class 16 at 40% — worth getting right when a single machine is a six-figure entry. Fleet buys at US auctions add duty, possible tariffs, and GST at the border on top of the hammer price, which we break down on our cross-border tax page for excavation contractors. Day one itself is standard but unforgiving: incorporate with share classes that leave room for the future holdco, open the RC, RT, and RP accounts, register WSIB, insure the fleet in the corporate name, and keep the entity current through ongoing compliance. We set the structure up in the right order and keep the leases, elections, and T2s aligned as the fleet grows.
