FAQs
What are T5018 filing requirements for Ontario contractors?
How does HST work for contractors and subcontractors?
Construction businesses that pay subcontractors for goods or services related to construction must report those payments to the CRA using Form T5018 within six months of their chosen reporting period.
Contractors making over $30,000 annually must register for and collect GST/HST. HST paid on business supplies and subcontractor invoices can be claimed as Input Tax Credits (ITCs) to offset HST collected.
What factors influence contractor bookkeeping costs?
How do I know if a worker is a subcontractor or an employee?
Bookkeeping costs depend on project volume, number of subcontractor accounts, payroll frequency, monthly receipt transactions, and whether job costing tracking is required.
The CRA considers factors like control over work, ownership of tools, financial risk, and integration into your business. Proper documentation and working terms determine official status.
How does job profitability tracking improve trade margins?
Job profitability tracking assigns direct materials, labor, and subtrade costs to specific contracts. This highlights low-margin job types so you can adjust estimate pricing and control job overhead.
