Contractor accountant in Barrie
Simcoe County has spent years building houses, subdivisions and the roads and services behind them for people moving north from the GTA. That work runs on Ontario’s holdback rules, WSIB and HST on every progress draw. EverStone is an accountant for incorporated contractors and a Barrie small business accountant, at fixed fees, online.
Quick answer: Barrie contractors deal with the Construction Act’s 10% holdback, HST that becomes payable on progress billings before the cash arrives, T5018 slips for subcontractors, and WSIB coverage that reaches further in construction than in most industries. EverStone handles the books, T5018s, payroll and the year-end T2 at a fixed fee agreed before work begins. Published fees start at $300 a month for bookkeeping and $100 for a personal return.

The same subcontractor and equipment questions come up for Barrie carriers and Barrie fabricators; the national contractor accounting page 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 on an improvement retains 10% of each payment as a holdback, released once the lien period has passed. For a subcontractor several tiers down, that money can sit for months after the work is finished. On the books it is a receivable, separate from ordinary accounts receivable, and it has to be tracked job by job so that each release is claimed and none is forgotten.
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 goes through the entries.
Progress billing and when HST becomes payable
HST does not wait for the cheque. On a progress billing, the 13% HST is generally payable on the earlier of the day you are paid and the day the invoice is issued or the payment is due. That means a Barrie contractor can owe HST on a draw that has not been paid, and a slow-paying builder can leave you financing the tax. The exception is the holdback itself: the HST on the retained portion is generally not payable until the holdback is paid or becomes payable.
Two habits help. Issue progress invoices that show the holdback separately, so the tax on each part is clear. And file HST often enough that the tax collected in a busy summer is remitted before it has been spent on materials and wages. Most contractors recover a lot of HST on purchases too, so the ledger has to code every input tax credit rather than leave them on the table.
Subcontractors, T5018 slips and classification
A business whose primary activity is construction reports payments to subcontractors for construction services on T5018 slips. The reporting period can be the calendar year or your fiscal year, and the return is due six months after the period ends. The information comes straight from the ledger, which is why subcontractor payments are coded by vendor from the start rather than pulled together in a rush.
The harder question is whether a worker is a subcontractor at all. That turns on the substance of the arrangement: who controls the work, who supplies the tools, whether the person can profit or lose, and whether they could send someone else. A tradesperson working only for you, on your schedule, with your tools, is the classic exposure, and reclassification brings CPP and EI with interest. See subcontractor versus employee.
WSIB in construction reaches further
Construction is where Ontario’s WSIB rules are broadest. Most construction employers must register, and coverage extends to many independent operators and some executive officers who would be outside the system in other industries. Premiums are based on insurable earnings and the classification of the work, and the payroll reported to WSIB should agree with the payroll on the books.
The detail that costs money is clearance. If you hire a subcontractor who is not in good standing with WSIB, you can be held responsible for their unpaid premiums. Getting a clearance certificate before paying each sub, and keeping it with their invoice, closes that off.
Residential building, and HST on a house
Contractors who build new homes rather than work for a builder face a different sales tax picture. A builder selling a new house charges HST on the sale, and the new housing rebates affect how the price is set and who claims what. A builder who builds a house or a rental unit and rents it out, rather than selling it, can be treated as having sold it to themselves and owe HST on its value. Renovations of existing homes follow the ordinary rules. None of this needs figures to understand, but it does need to be settled before the first contract is signed rather than after the house is finished.
Equipment, vehicles and the quiet season
Trucks, trailers, excavators and tools are recovered through capital cost allowance at rates set by their class, not expensed when bought. Timing a purchase before year-end can bring the deduction forward, but only helps if the year’s income can use it. Winter is when many Barrie crews slow down, which is also when the numbers from the season can be looked at properly. That review shows which jobs made money, how much tax is coming, and whether the instalments you are paying match the year you actually had.
What lenders, bonding companies and builders ask for
Growth in construction usually depends on someone else’s comfort: a bank extending equipment finance, a surety backing a contract, or a general contractor checking a new trade before letting them on site. Each of them asks for financial statements. For most owner-managed trades, a compilation engagement is the right form: statements prepared from your records with a report that says plainly it is not an audit or a review. Where a counterparty needs assurance, that is a different engagement, and we will tell you before you send something that will not satisfy them.
The request always comes with a deadline, often in the middle of the season. Statements are quick to produce when the books have been kept monthly, the holdbacks are listed by job and the work in progress is known. They are slow and expensive when the year has to be rebuilt first. That is the practical case for keeping the books current: not tidiness, but being able to say yes to the next contract.
