Cleaning business tax services: HST on every contract, deductions on every kilometre

HST: always charged, unevenly felt

Cleaning is a taxable supply — there is no exemption for residential work, janitorial contracts, or post-construction cleans. Once your taxable revenue passes the $30,000 small-supplier threshold over four rolling calendar quarters, registration is mandatory and every invoice carries 13% in Ontario. The interesting part is not whether to charge it but what it does to each client's price.

A registered office, clinic, or warehouse client claims the 13% back as an input tax credit, so your HST is invisible to them. A homeowner pays it in full. So do most condominium corporations and residential landlords, because they make exempt supplies and recover nothing. That asymmetry drives two opposite strategies: a residential-focused solo operator under $30,000 may rationally delay registering to stay 13% cheaper than registered competitors, while a commercial-focused company should register voluntarily on day one to recover HST on chemicals, equipment, and vehicles.

Commercial contracts add one more HST wrinkle worth knowing: when a client goes under owing you months of invoices, the HST you already remitted on those unpaid bills can be recovered through a bad-debt adjustment on a later return — but only after the receivable is actually written off in your books, so the paperwork order matters.

The quick method rewards labour-heavy cleaners

Payroll carries no HST, and wages are usually a cleaning company's biggest cost — which means few input tax credits and exactly the profile the quick method rewards. A registered service business with taxable sales of $400,000 or less (tax included) can elect to remit 8.8% of its Ontario sales instead of the full 13% collected, keep the spread, and take a 1% credit on the first $30,000 each year. Capital purchases such as vans still earn full input tax credits on top. We run the quick-method math against actual ITCs every year, because the answer flips once equipment spending ramps up.

Vehicles, machines, and supplies: where the deductions live

The vehicle file is the one CRA asks about first. A cargo van used to haul equipment sits in Class 10 and depreciates at 30% declining balance with no cost ceiling; a passenger car lands in Class 10.1, where the depreciable cost is capped ($38,000 before tax for 2025 purchases) and no terminal loss is allowed on sale. Travel between client sites is deductible; a kilometre logbook splitting business from personal use is what makes fuel, insurance, and repair claims stick.

• Consumables — chemicals, cloths, liners, PPE — are deducted in full as used.
• Floor scrubbers, carpet extractors, and burnishers are Class 8 equipment at 20% declining balance.
• Uniforms, branded gear, and phone plans are deductible where the business use is documented.

T2125 or T2: structure follows the contract base

A solo operator reports on a T2125 with the personal return, and that is the right home until profit clearly exceeds what you draw to live on. Incorporating moves retained profit to roughly 12.2% Ontario tax on the first $500,000 under the small business deduction, which matters once you are financing a second crew or a truck-mounted unit from after-tax dollars. Subcontracted cleaners add a filing layer: genuine independents invoice you — with HST you recover if they are registered — and fee-for-service T4A questions follow, while misclassified employees create source-deduction liabilities. We cover that boundary on our cleaning business payroll page.

Instalments: the growth tax nobody warns you about

Instalments start quietly. Owe more than $3,000 at filing — personal, corporate, or GST/HST for annual filers — and CRA expects payments through the following year, quarterly for most small CCPCs with clean compliance. The trap for a scaling cleaner is that instalments are set from last year's smaller numbers, so a year of new contracts ends with a large balance plus interest that no reminder letter preceded. We reset the schedule after every filing and again mid-year when a major contract lands. And if your growth involves a US franchisor — royalty payments south carry their own withholding rules — that side lives on our cross-border tax page for cleaning businesses.
