Our Service Offerings

An Accounting Partner Built Around the Contracting Business

Contracting firms face financial realities that standard bookkeeping overlooks. Whether you're two years into self-employment or running an established firm, we manage these conditions with accuracy and foresight to deliver reliable numbers and full compliance.

Industry-Specific Tax Expertise

Our accountants for contractors understand how the CRA reviews contractor files and how project costs should be allocated. They also know which deductions are most frequently overlooked, including tools, vehicles used for business purposes, and equipment acquired during the year.

Year-Round Financial Guidance

Big financial decisions in contracting rarely line up with tax season. Before you commit to a major contract, we assess how its draw schedule, holdback terms, and payroll requirements will affect your working capital, so you can take on larger projects without straining your cash flow. We offer the same guidance when you're hiring, financing equipment, or preparing for a seasonal slowdown.

Advice Aligned With Your Business Structure

The appropriate strategy for a sole proprietor differs considerably from that of an established corporation with employees and family shareholders. We assess your current structure, income level, and objectives, then advise on compensation, retained earnings, and reporting obligations accordingly.

Core Services Built for Contractor Confidence

Tax Services

Contractor tax returns involve many variables. For incorporated businesses, you also need to balance salary and dividends. Our tax team prepares T1 and T2 returns, manages HST filings, and responds to CRA correspondence on your behalf. We also set up installment schedules so large balances don't build up by year-end. Our accountants for contractors conduct forward-looking planning as well, so that equipment purchases and other major expenditures are timed to your advantage.

Assurance Services

Surety companies, lenders, and project owners frequently require financial statements before approving bonding facilities, credit, or larger contracts. Our assurance team prepares compilation engagements, review engagements, and audits to the standard each stakeholder requires. We advise you in advance on the level of assurance needed, as a review engagement is often sufficient and costs less than a full audit. Statements are prepared on a timeline that supports upcoming tenders and bonding renewals.

Advisory Services

As a contracting business grows, financial decisions require more than historical records. Through our CFO advisory service, we prepare cash flow forecasts aligned with your draw schedules, analyze profitability by project type, and identify where margins are being lost. We also support planning for seasonal slowdowns, fleet and equipment expansion, and long-term succession. Reporting is delivered in a concise monthly format designed for decision-making.

Why Contractor Finances Require a Specialist Accountant

01

Incorporation vs. Sole Proprietorship

Incorporation can lower the tax on retained profits, but it adds T2 filings, payroll, and stricter bookkeeping. Contractors serving a single client also risk being classified as a personal services business, which removes the small business deduction. We model both structures on your actual income and recommend the more efficient option.

02

HST Registration, Remittance and Input Tax Credits

HST registration is mandatory once taxable revenues exceed $30,000 in a calendar quarter or over four consecutive quarters. Late filings and unsupported input tax credits are common triggers for a CRA review. We manage registration, filing and documentation in full, and assess whether the Quick Method would reduce your remittance.

03

Job Costing, Holdbacks and Work in Progress

Progress draws and the 10% holdback under Ontario’s Construction Act mean income is often earned well before it is received. We implement job costing that shows the true margin on each project. We also track holdbacks and work in progress accurately, so your statements satisfy sureties and lenders.

04

T5018 Reporting, Subcontractors and WSIB Compliance

Construction businesses must report subcontractor payments on T5018 slips within six months of the reporting period’s end. General contractors also require valid WSIB clearance certificates before releasing payment. We maintain these records and flag missing certificates before payments go out, protecting you from liability for unpaid premiums.

06

CRA Audit Risk and Worker Classification

The CRA regularly examines whether contractors are, in substance, employees. A reclassification can lead to denied expenses, CPP and EI assessments, and retroactive penalties. Our accountants for contractors review your agreements against the CRA’s criteria and maintain the documentation that supports your self-employed status.

Other Sectors We Serve

Frequently Asked Questions

A general accountant can prepare a standard return. Accountants for contractors bring specific knowledge of worker classification, progress billing, holdbacks, T5018 reporting, and HST compliance. That expertise typically leads to more accurate filings, fewer reassessments, and deductions you might otherwise miss. It is particularly valuable for contractors with subcontractors or bonding requirements.

Incorporation generally merits consideration once your business income consistently exceeds your personal living requirements, as income retained in a corporation is taxed at a lower rate. Liability exposure, the number of clients you serve, and whether you employ staff are also relevant. Before you proceed, we prepare a comparative analysis of both structures, including the after-tax impact over several years.

Eligible deductions commonly include tools and equipment, the business portion of vehicle costs, home office expenses, insurance, software, professional fees, and subcontractor payments. Incorporated contractors may also pay reasonable salaries to family members who work in the business. Eligibility depends on your structure and supporting documentation, which we review for every client before each return is filed.

Contractors should retain all invoices, receipts, and contracts, along with a vehicle mileage log and payroll records. You should also keep subcontractor payment details for T5018 reporting and copies of WSIB clearance certificates. The CRA generally requires records to be kept for six years. We set up an efficient record-keeping system that keeps your books current throughout the year.
