GST/HST filing in Mission

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

The rule is simple but widely misremembered. Registration becomes mandatory once taxable revenue exceeds $30,000 over four consecutive calendar quarters. That window rolls and is tested continuously. It is not your fiscal year, not a calendar year, and not something to check only at tax time.

A business growing through summer can cross the line in August and not notice until March, after seven months of invoices without GST. The business still owes the tax. Asking customers months later for 5% they were never billed turns a tax problem into a customer problem. Our registration guide covers the test and mechanics.

Why voluntary registration is often the right call anyway

Below the threshold, registering is optional and often worthwhile. Registrants claim input tax credits on GST paid, which can be substantial on first-year tools, equipment, vehicles and services. Small suppliers recover none.

The trade-off is usually smaller than it looks. Registering means charging GST and filing on schedule. If your customers are registered businesses, the GST costs them nothing because they claim it back, so voluntary registration is close to a free option. Selling to households is different: the 5% is a real price increase.

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

Registration assigns a reporting period by annual taxable supplies. Monthly and quarterly filers file and pay one month after the period. Annual filers file and pay three months after year-end (March 31 for a December 31 corporation); a December 31 sole proprietor files by June 15 and pays by April 30. Annual filers with prior-year net tax of $3,000 or more owe quarterly instalments, often learned from a notice. See the deadlines page.

Build one habit from the first registered invoice: the GST in a deposit is not revenue. Move it to a separate account the day it arrives. Treating collected tax as working capital is the most common way a profitable small business ends up with a CRA balance it cannot clear.

Remote GST/HST filing

GST/HST filing for Mission clients is remote. There is no Mission office and no local team. Meetings are virtual, documents are e-signed, and you deal with the CPA directly. Returns come from the same bookkeeping as the corporate return, so sales figures agree.

Where the same file also needs corporate returns for Mission owners and the Mission personal tax page, that is handled in one engagement.

Businesses that also want the Mission bookkeeping engagement and getting the Mission returns filed can have both quoted together.
