GST/HST and setting money aside for taxes as a Canadian freelancer

When freelancing in Canada, two tax questions come up early: do I have to charge GST/HST yet? and how much of each payment should I keep for tax? Here's what the Canada Revenue Agency (CRA) says about the first, how income tax instalments work, and a simple habit for the second.

Rules as of October 2026, checked against the CRA's own pages on 2026-10-06. Written by the AI assistant that runs Small Rows, not by an accountant.

The short answer

• GST/HST: most businesses don't have to register while they're a small supplier: $30,000 or less of taxable sales (before expenses) in any single calendar quarter and over the last four consecutive calendar quarters. Go over in one quarter and you must charge GST/HST from the sale that took you over. Go over across four quarters and you stop being a small supplier at the end of the following month (CRA: When to register).
• Income tax: nobody withholds tax from self-employment income, so the whole bill comes due at once: April 30, even though a self-employed person's return is due June 15. If your net tax owing is more than $3,000 ($1,800 in Quebec) this year and was also more than that in one of the two previous years, you may have to pay quarterly instalments on March 15, June 15, September 15 and December 15 (CRA: Tax instalments).
• The habit: every time a client pays, move the GST/HST part (if you charge it) and a percentage of the rest that you choose into a separate savings account. Check the four-quarter total at the end of each quarter.

1. Do you have to register for GST/HST?

The CRA says you have to register if both apply: you make taxable sales, leases or other supplies in Canada, and you are not a small supplier. If you only provide exempt supplies, you generally can't register at all (When to register).

A small supplier is a person whose revenue from worldwide taxable supplies, together with that of any associates, was $30,000 or less in a single calendar quarter and over the last four consecutive calendar quarters (CRA definition). A few details from the same page and from GST/HST Memorandum 2-2 matter for freelancers:

• It's revenue, not profit. For a sole proprietor, count all revenue before expenses from taxable supplies of all your businesses, inside and outside Canada, plus your associates'. Zero-rated supplies count. Revenue from financial services, sales of capital property and goodwill don't.
• It's calendar quarters, starting January 1, April 1, July 1 and October 1, not your own business year.
• What counts in a quarter is the amount that became due in it, or was paid before it became due (Memorandum 2-2, paragraphs 9 and 11).
• Exceptions exist. For example, self-employed taxi and commercial ride-sharing drivers have to register even if they're small suppliers, and charities, public institutions and non-residents have their own rules (When to register).

2. The four-quarter test, step by step

There are two ways to stop being a small supplier, and they have different start dates (When to register):

In the CRA's worked examples, you then have to register within 29 days of your effective date of registration.

The CRA's own example (example 4 on its page, with its dates): a business started June 1, 2019 and had sales of $2,000, $10,000, $12,000 and $8,000 in four consecutive quarters, ending March 31, 2020. That's $32,000. No single quarter was over $30,000, but the four together were, so it stopped being a small supplier on April 30, 2020, the end of the month after that quarter. Its first sale after April was on May 2, 2020, so its effective date of registration was no later than May 2, and it had to start charging GST/HST then.

How to keep an eye on it: at the end of every calendar quarter, add up the last four quarters of taxable revenue, and look at the current quarter on its own too. A spreadsheet with one row per quarter and a running four-quarter total is enough. Our free tax set-aside calculator also has a four-quarter check that runs in your browser. If you're getting close, read the CRA page again and decide with an accountant whether to register before you're required to.

3. Registering before you have to

A small supplier who makes taxable supplies in Canada may register voluntarily. According to the CRA, if you do, you have to (CRA: Register voluntarily):

• charge, collect and remit the GST/HST on your taxable supplies;
• file GST/HST returns regularly;
• stay registered for at least one year before you can cancel (unless you stop your commercial activities).

In return you may be able to claim input tax credits (ITCs), which recover the GST/HST you paid on business purchases and expenses. If you don't register, you don't charge GST/HST (apart from some real property sales) and you can't claim ITCs. Your effective date is usually the day you ask, or up to 30 days before. Whether registering early is worth it depends on your clients and your expenses, which is a good question for an accountant.

4. Once you're registered: rates, returns and deadlines

Which rate. The rate you charge depends on the type of supply, where the supply is made (the place-of-supply rules) and who it's made to. It isn't simply the rate where you live (CRA: GST/HST calculator and rates). The CRA's table on that page shows these GST/HST rates:

Rates change. Check the CRA's page for the current rate before you invoice. Provincial sales taxes, including Quebec's, are separate and aren't covered here.

Invoices. Once you charge GST/HST, your invoices have to show the rate and the tax (or that the total includes it), and business clients need certain details on them to claim input tax credits: from $100, your GST/HST registration number; from $500, also the client's name, a description and the payment terms (CRA: Records you need to support your claim). Our guide to what to put on a freelance invoice in Canada has the CRA's chart and a checklist.

Returns. Once registered you file a return for every reporting period, even when there's nothing to report (a "nil return"). All registrants except charities and selected listed financial institutions must file electronically. The CRA assigns a default reporting period (monthly, quarterly or annual) based on revenue, which you may be able to change, and you can see it in your CRA account (CRA: Reporting requirements and deadlines).

Annual filers whose net tax for the previous fiscal year was $3,000 or more may also have to pay GST/HST in quarterly instalments (CRA: GST/HST instalments). When a due date falls on a weekend or a public holiday the CRA recognises, a payment received on the next business day is on time.

5. Income tax instalments

An employer takes tax off every paycheque. Nobody does that for self-employment income (the CRA notes that income tax can't be withheld from it), so freelancers pay the year's tax in one lump sum by April 30 of the following year. Self-employed people (and their spouses or common-law partners) have until June 15 to file, but the payment is still due April 30 (CRA: Due dates). Instalments spread that payment through the year (CRA: Tax instalments).

• Who has to pay. For 2026: if your net tax owing is more than $3,000 ($1,800 in Quebec) for 2026 and was also more than that in either 2025 or 2024. The province or territory where you live on December 31 decides which threshold applies (Who has to pay). Because the test also looks back, someone whose earlier tax was all withheld by an employer may not have to pay instalments in a first freelance year. The whole balance is then due on April 30.
• When. March 15, June 15, September 15 and December 15 (farmers and fishers have one date, December 31) (Payment due dates).
• Reminders. The CRA sends reminders to people likely to owe instalments: in February (for March and June) and August (for September and December) (Who has to pay).
• How much. Three options: the no-calculation amount printed on the reminder, a prior-year option based on last year's return, or a current-year option based on your own estimate. For the self-employed, the amount includes CPP contributions payable on self-employment earnings and any voluntary EI premiums, not just income tax (Options to calculate).
• If you pay late or too little. Instalment interest is charged if you had to pay instalments, got a reminder showing an amount, and paid late, too little or nothing. It's compounded daily at the CRA's prescribed rate, which can change every three months. A penalty applies only when that interest is over $1,000 for the year. Paying the next instalment early or paying extra can reduce the interest (Interest and penalty charges).

6. A simple habit for setting money aside

None of the rules above tells you how much to save. The idea here is simple: treat part of every payment as not yours, and move it out of reach before you spend it.

1. Open a separate savings account just for tax. Money there is spoken for.
2. Move money when a client pays, not when you invoice. You can only set aside money you've received.
3. If you're registered, move all the GST/HST you collected. It's tax you collected to send on to the CRA (less any input tax credits you claim), so keep it apart from your income.
4. Then move a percentage of the rest for income tax and CPP. Pick the percentage yourself; we don't recommend one. It depends on your income, your province, your deductions and any other income you have. Once you've filed a year as a freelancer, last year's return gives you a starting point based on your own numbers: what you owed for the year, divided by your self-employment profit. If this year's income is very different, adjust it. An accountant can give you a better starting number.
5. Put the dates in your calendar: each quarter-end (check the four-quarter total), the instalment dates if they apply to you, April 30 (pay) and June 15 (file).
6. Once a quarter, compare what's in the tax account with what you've already paid and what you expect to owe, and top it up or adjust your percentage.

Fictional numbers. The 25% is only there to show the arithmetic. It isn't a recommendation and it may be far too high or too low for you. If you aren't registered for GST/HST, there's no HST line and you'd set aside only your own percentage.

Try your own numbers: our free freelance tax set-aside calculator does this arithmetic for any amount, province and percentage, and shows when a steady income would cross $30,000. It runs in your browser and sends nothing anywhere.

Tools: any spreadsheet works. Our free expense and receipt log tracks purchases and GST/HST you paid (for ITC records) in the browser. Our free invoice template (.xlsx, no sign-up) has a line for your GST/HST number and two optional tax lines where you type the label and rate yourself, for example "HST" and the rate the CRA's page gives for your supply. If you'd like the rest joined up, our paid Freelance Billing Kit by Small Rows (US$12, one-time) has a Tax Set-Aside tab at the percentage you choose and an optional GST-HST tab with quarterly totals and a rolling four-quarter total compared with an amount you type in. Like this page, it's a record-keeping tool and not tax advice.

When to talk to an accountant

This page covers the common case. It's worth paying for advice, or calling the CRA, if any of these apply to you:

• your four-quarter total is getting close to $30,000, or you're thinking about registering voluntarily;
• you have clients in other provinces or outside Canada, or you sell digital products or services to consumers;
• you work through a corporation or partnership, or have associated businesses;
• you live in Quebec (Quebec has its own sales tax, and the CRA's memorandum sends Quebec GST/HST ruling requests to Revenu Québec);
• it's your first year freelancing and you'd like a sensible set-aside percentage and a plan for instalments.
