How to File Your GST/HST Return in Canada (2026)

The short answer

To file a GST/HST return in Canada you report the tax you collected, subtract your input tax credits (ITCs) on business purchases, and remit the difference to the CRA — most freelancers file online through CRA's My Business Account or NETFILE. The bigger money question is how you calculate it: the regular method (track every ITC) versus the Quick Method (a flat remittance rate), which for a typical Ontario service business means remitting 8.8% of your HST-included revenue instead of the full 13% you collect.

That second sentence is where real dollars live, so most of this guide is about it. But first, the mechanics — because the return itself is simpler than it looks.

(This is the downstream companion to our $30,000 registration threshold guide. That post answers whether and when you have to register; this one answers what you do once you are registered and a return is due.)

What "filing a GST/HST return" actually is

A GST/HST return is a short reconciliation. Over your reporting period you did two things: you charged tax on your sales, and you paid tax on some of your business purchases. The return nets them:

• GST/HST you collected on sales (this is line 105 on the return).
• Minus your input tax credits — the GST/HST you paid on eligible business expenses (line 108).
• Equals your net tax — what you send the CRA (or, if your ITCs were larger, a refund).

The single most important thing to internalise: the tax you collected was never your money. It is the CRA's money, sitting with you on its way to Ottawa. Treat it as revenue and filing becomes a shock; treat it as money held in trust and filing becomes a transfer you already had set aside.

The five steps to file

1. Total up the GST/HST you collected across the period.
2. Total up your ITCs — the recoverable tax on your business purchases (regular method only; the Quick Method handles this differently, below).
3. Calculate your net tax — collected minus ITCs, or the Quick Method formula.
4. File online. Almost every registrant must now file electronically. The two routes freelancers use most are your CRA account (My Business Account), which has GST/HST NETFILE built in, or the standalone GST/HST NETFILE form, which needs a 4-digit access code. (Filing by phone via TELEFILE and by paper still exist, but paper filing carries a penalty for most businesses.)
5. Remit by the deadline tied to your reporting period. You can file even if you owe — just make sure the payment lands on time.

The decision that actually moves money: regular vs Quick Method

Here is the part almost no "how to file" article covers, and it is the one worth real attention.

The regular method

You remit exactly what you collected, minus every input tax credit you can document. Net tax = GST/HST collected − ITCs. The upside: if you have significant business costs (inventory, subcontractors, equipment, software), your ITCs are large and you remit less. The cost: you have to track every ITC — keep every receipt, categorise it, and be able to defend it if the CRA asks.

The Quick Method

Instead of tracking ITCs on your day-to-day costs, you remit a flat percentage of your GST/HST-included sales. The rate is deliberately set below what you charged, and that gap is the CRA's built-in estimate of the ITCs you would otherwise have claimed. You still charge your customers the normal GST/HST — you just get to keep part of it.

For a service business located in Ontario, the Quick Method remittance rate is 8.8% of your HST-included sales — against the 13% HST you actually collected. On top of that, the Quick Method gives you a 1% credit on the first $30,000 of eligible supplies each fiscal year. You can also still claim ITCs on capital purchases (a laptop, a camera), just not on everyday operating costs.

A worked example (estimate, not advice)

Say you're an Ontario consultant. Over the year you bill $100,000 and add 13% HST, so you collect $13,000 in HST. Your clients pay you $113,000 in total — that's your "GST/HST-included sales."

	Regular method	Quick Method
HST collected	$13,000	$13,000 (you still collect it)
Remittance calculation	$13,000 − your actual ITCs	8.8% × $113,000 = $9,944
Minus 1% credit on first $30,000	—	− $300
Roughly what you remit	$13,000 − ITCs (e.g. $11,800 if ITCs ≈ $1,200)	≈ $9,644

In this example the Quick Method leaves roughly $2,000 more in the business than the regular method — because a lean service business doesn't have enough ITC-eligible costs to beat the flat rate. Flip the numbers — heavy equipment, inventory, big subcontractor bills — and the regular method wins, because your real ITCs exceed what the flat rate assumes. The honest rule of thumb: the Quick Method favours low-expense service businesses; the regular method favours high-expense ones. These are estimates to frame the decision, not tax advice for your specific situation — the exact break-even depends on your costs, so it's worth a conversation with an accountant before you elect.

Are you eligible for the Quick Method?

You can elect the Quick Method if your revenues (including the GST/HST) from annual worldwide taxable supplies — yours and your associates' — are not more than $400,000 over the relevant four consecutive fiscal quarters. A handful of businesses are specifically excluded, including accountants, bookkeepers, financial consultants, tax preparers, and certain other listed professionals. You have to elect the Quick Method with the CRA before it applies — it isn't automatic, and it isn't retroactive.

A quick word on ITCs (for the regular method)

Input tax credits let you recover the GST/HST you paid on purchases used to run your business — software, equipment, professional fees, supplies, a share of home-office and vehicle costs. On a regular-method return you subtract your total ITCs from what you collected, so you only remit the net. The mechanics of tracking them day to day are covered in our HST/GST tracking guide. The one rule that matters at filing time: keep the receipts that show the tax paid — the CRA can ask you to support every ITC you claim.

Your filing period and deadline

The CRA assigns a default reporting period based on your revenue:

Annual taxable supplies	Assigned reporting period
$1,500,000 or less	Annual
More than $1,500,000 up to $6,000,000	Quarterly
More than $6,000,000	Monthly

Most freelancers and small businesses land in the first row and file annually — though you can ask the CRA for a more frequent period if you'd rather remit in smaller pieces. Your deadline follows your period:

• Monthly and quarterly filers: file and pay one month after the period ends. (A quarter ending March 31 is due April 30.)
• Most annual filers: file and pay three months after your fiscal year-end.
• Sole proprietors with a December 31 year-end and business income get a split deadline: pay by April 30, file by June 15.

You still have to file even if you had no activity or owe nothing — that's a "nil return." And you must file even when you can't pay in full; interest is cheaper than a missed return.

Where your filing figure should already be sitting

The reason GST/HST filing feels stressful is almost never the arithmetic — it's discovering, at the deadline, that the money you collected got spent as if it were income. VRITTI is a Canadian self-employed money app that tracks the GST/HST you collect in its own compartment — the CRA's money, held in trust — so your filing figure is already sitting there, not spent. When the return is due, the number you need is a number you've been watching all year, not a surprise you reconstruct from a shoebox.

VRITTI is coming soon for Canadian freelancers and sole proprietors. If a calmer relationship with the CRA's share sounds worth it, you can join the waitlist — no pressure, no download yet, just an early spot when it opens. In the meantime, our tax set-aside calculator helps you park the right amount as you go.

The one-paragraph version

Filing a GST/HST return means reporting what you collected, subtracting your ITCs, and remitting the net to the CRA — filed online through My Business Account or NETFILE. The decision worth thinking about is the method: the regular method (track every ITC) versus the Quick Method (a flat rate — 8.8% of HST-included sales for an Ontario service business, plus a 1% credit on your first $30,000), which usually wins for low-expense service businesses and loses for high-expense ones. Know your reporting period, keep the tax you collect apart from day one, and the return stops being a scramble.
