HST for Ontario contractors

The small supplier threshold has two tests, and the one that catches a contractor is the one nobody warns you about. These guides cover when you have to register, what you charge and on which part of the job, what comes back to you as an input tax credit, and how to keep books that turn a CRA letter into a morning of work.

3 ways to move forward

Practical guidesHST without the surpriseNobody writes to tell you that you crossed the threshold. Register on time, charge it on the whole invoice, keep the collected money separate, and read your return on the CRA's own line numbers before you sit down with your accountant.After you qualifyCRA RegistrationBusiness Number, HST/GST, payroll deductions, corporate income tax: every CRA account your construction company needs.Practical guidesBooks that stand upThe fear is being asked a question about your own business and not being able to answer it. The way out is records made as the work happens, by the system that raised the invoice, so there is nothing to reconstruct in March.
