GST/HST filing in Mission

The threshold is a rolling test, not a year-end one

The rule that catches growing Mission businesses is not complicated, but it is misremembered almost universally. Registration becomes mandatory once taxable revenue exceeds $30,000 over four consecutive calendar quarters. That is a rolling window, tested continuously — it is not your fiscal year, it is not a calendar year, and it is not something you look at when you prepare your return in the spring.

A business that grows steadily through a summer can cross the line in August and not realise until the following March. By then it has issued seven months of invoices with no GST on them. The liability does not disappear because the tax was never charged: the business owes it. Going back to customers months later to ask for 5% they were never billed is, in practice, a way of turning a tax problem into a customer problem. Our registration guide works through the test and the mechanics.

Why voluntary registration is often the right call anyway

Below the threshold, registration is optional — and frequently worth doing. A registrant claims input tax credits on the GST it pays. For a Mission business in its first year buying tools, equipment, a vehicle, materials or professional services, that recoverable tax can be substantial, and a small supplier recovers none of it.

The trade-off is real but usually smaller than it looks. Registering means charging GST, which matters if you sell to consumers who cannot recover it, and it means filing returns on a schedule. If your customers are themselves registered businesses — other contractors, other companies — the GST you charge costs them nothing, because they claim it back. In that situation voluntary registration is close to a free option on your input tax. The calculation is different for a business selling to households, where the 5% is a genuine price increase.

Once registered: frequency, deadlines and the money that is not yours

Registration assigns a reporting period based on annual taxable supplies. Monthly and quarterly filers file and pay one month after the reporting period ends. Annual filers with a December 31 fiscal year-end file by June 15 with the balance due April 30; other annual filers file and pay three months after their fiscal year-end. Annual filers whose net tax for the previous year was $3,000 or more also owe quarterly instalments during the year, which is the obligation most new annual filers discover from a notice rather than from a plan. The dates are set out on the deadlines page.

The habit worth building from the first registered invoice is simple: the GST portion of a deposit is not revenue. Move it to a separate account the day it arrives. Businesses that treat collected tax as working capital create their own crisis at the filing date, and it is the single most common way an otherwise profitable small business ends up with a CRA balance it cannot clear.

Remote, with no Mission office

EverStone works from a single office in Abbotsford and has no Mission location. Everything runs online — a video call to work out whether and when you need to register, secure exchange for records, e-signature for approvals. For a business at the stage where the owner is doing the work as well as running it, that is usually the deciding factor. The GST calculator is free to use if you want to model what registration would mean for your pricing first.
