Updated September 2026 . The same subcontractor and equipment questions come up for Barrie carriers and [Barrie fabricators](https://www.everstonecpa.com/manufacturer-accountant-barrie); the national [contractor accounting page](https://www.everstonecpa.com/contractor-accountant) covers what the CRA looks at on a construction file. ## The 10% holdback, and where it sits on the books Under Ontario’s Construction Act, the payer holds back 10% of each payment until the lien period ends. A subcontractor several tiers down can wait months. It is a separate receivable, tracked by job so every release is claimed. At year-end the holdback raises a timing question. The work was done and invoiced, but the money is not yet due. Getting the cut-off right on each open job, what was earned, what was billed and what was retained, is the single item most likely to move a contractor’s taxable income. [Construction holdbacks](https://www.everstonecpa.com/blog/construction-holdbacks-accounting-canada) goes through the entries. ## Progress billing and when HST becomes payable HST does not wait for the cheque. On a progress billing, the 13% is generally payable at the earlier of payment or the invoice or due date. So a Barrie contractor can owe HST on an unpaid draw. But HST on the holdback is generally not payable until the holdback is paid or payable. Two habits help: show the holdback separately on invoices, and file HST often enough that summer's tax is remitted before it is spent. Contractors also recover much HST on purchases, so code every input tax credit. ## Subcontractors, T5018 slips and classification A business mainly in construction reports payments to subcontractors for construction services on T5018 slips, due six months after the calendar or fiscal period ends. The data comes from the ledger, so code subcontractor payments by vendor from day one. The harder question: is the worker a subcontractor at all? It turns on control, tools, profit or loss, and whether they could send someone else. A tradesperson working only for you, on your schedule and tools, is the classic risk; reclassification brings CPP and EI with interest. See [subcontractor versus employee](https://www.everstonecpa.com/blog/subcontractor-vs-employee-cra). ## WSIB in construction reaches further WSIB rules are broadest in construction. Most construction employers must register, and coverage reaches many independent operators and some executive officers. Premiums follow insurable earnings and work class, and WSIB payroll should match the books. The costly detail is clearance. Pay a sub not in good standing and you can owe their premiums. Get a clearance certificate before each payment and file it with the invoice. ## Residential building, and HST on a house Contractors who build new homes face a different sales tax picture. A builder selling a new house charges HST, and new housing rebates affect pricing and who claims what. A builder who rents out a house or unit instead of selling it can be treated as selling it to themselves and owe HST on its value. Renovations follow the ordinary rules. Settle this before the first contract is signed, not after the house is finished. ## Equipment, vehicles and the quiet season Trucks, trailers, excavators and tools go through [capital cost allowance](https://www.everstonecpa.com/blog/capital-cost-allowance-cca-classes-canada) at class rates. Buying before year end helps only if income can use the deduction. Winter, when Barrie crews slow, is the time to review the season: which jobs paid, what tax is coming, whether instalments fit. ## What lenders, bonding companies and builders ask for Growth needs someone else’s comfort: a bank, a surety or a general contractor vetting a trade. Each wants financial statements. For most trades a [compilation engagement](https://www.everstonecpa.com/compilation-engagement-canada) fits, with a report saying it is not an audit or review. If assurance is needed, we tell you before you send something that falls short. The request always has a deadline, often mid-season. Statements are quick when the books are kept monthly, holdbacks are listed by job and work in progress is known; slow and costly when the year must be rebuilt. That is the case for current books: being able to say yes to the next contract. ## What a Barrie contractor has to get right What a Barrie contractor has to get right The items that decide a contractor’s year — for a business operating in Barrie, Ontario | Item | Why it matters | | 10% holdback | Retained on each payment and tracked job by job until released | | HST on progress billing | Generally payable when invoiced or due, whichever is first; the holdback portion later | | T5018 slips | Due six months after the end of the reporting period | | WSIB clearance | Obtained for each subcontractor before payment | | Sales tax where you operate | 13% HST, one registration and one return | Source: [Construction & trades accounting](https://www.everstonecpa.com/construction-trades-accounting).

Common questions ## Barrie accounting for construction contractors FAQ **Do Barrie contractors file T5018s?** If construction is your main activity and you pay subcontractors for construction services, yes. We prepare them from the ledger and file them within six months of the end of your reporting period. [Ask about your case →](https://www.everstonecpa.com/quick-question) **Do I owe HST on a progress invoice that has not been paid?** Generally yes, once the invoice is issued or the payment is due. The HST on the holdback portion is generally deferred until the holdback is paid or becomes payable. **How is the holdback treated at year-end?** As a timing question. We review each open job at the cut-off to separate what was earned in the year from what was simply billed or banked. **Does WSIB cover me as the owner?** In construction, coverage can extend to independent operators and some executive officers. Check your own status with WSIB rather than assuming either way. **What does a trades corporation pay for accounting?** A typical bundle of bookkeeping, payroll and the year-end T2 with statements usually runs $500–$700 a month, fixed in writing before we start. **What does an accountant cost for a Barrie construction business?** Barrie businesses pay the same published fees as everyone else. Monthly bookkeeping starts from $325 a month and a personal return from $125; a corporate return is quoted after we review your enquiry. A single question can go to a 45-minute Advice Call, a flat fee of $225 + GST. Every fee is fixed in writing first.
