GST Quick Method explained for Canadian small businesses

The GST Quick Method lets eligible small registrants remit GST/HST as a flat percentage of their taxable revenue, rather than tracking most input tax credits (ITCs) on every purchase. If your worldwide taxable supplies are $400,000 or less and you have a permanent establishment in Canada, you likely qualify. To get started, file Form GST74 or use My Business Account to make the election. Note that accountants, bookkeepers, lawyers, and listed financial institutions cannot use this method, regardless of revenue.

A few quick points before you read further:

• The GST Quick Method is officially documented in CRA guide RC4058, which is the authoritative source for rates, eligibility, and election rules.
• T4A slips, which report service payments to contractors, do not include GST/HST amounts. The CRA requires payers to exclude sales tax from T4A slip totals. This differs from how GST/HST is tracked in your own books.
• T4 slips report employment income and payroll deductions. T3 slips report trust income (such as investment fund distributions). T5 slips report investment income like dividends and interest. T4A slips cover other income, including self-employment and contractor payments, but always without GST/HST.

Key takeaways

The GST Quick Method saves time and often saves tax for service-based small businesses with low expenses, but it requires a deliberate eligibility check and a real numbers comparison before electing.

Consult RC4058 and Form GST74 for the official eligibility rules, current remittance rates, and election procedures.

What is the GST Quick Method and how does it differ from regular accounting?

The Quick Method is a CRA-approved simplified accounting option. Instead of calculating the exact GST/HST you collected minus every ITC you are entitled to claim, you multiply your total taxable revenue (including the GST/HST charged) by a set remittance rate. The difference between what you collected from customers and what you remit to the CRA stays in your pocket as a bookkeeping benefit.

Under the regular method, you track every dollar of GST/HST collected and every dollar of GST/HST paid on business expenses, then remit the net amount. That works well when your eligible expenses are high, because the ITCs reduce your remittance significantly. The Quick Method trades that precision for simplicity.

Here is what changes when you switch to the Quick Method:

• What you stop tracking: Most ITCs on day-to-day operating expenses (supplies, rent, professional fees, etc.).
• What you must still track: Total taxable supplies including GST/HST, exempt and zero-rated sales, and any excluded supplies that must be reported under the regular method.
• What stays the same: You still charge customers the correct GST/HST rate. The method only changes how you calculate your remittance, not your obligation to collect tax.
• Reporting differences: Your GST/HST return uses different line calculations, and you still claim ITCs on certain capital purchases (such as equipment) even under the Quick Method.

Canada’s streamlined accounting options include both the Quick Method and the Streamlined Input Tax Credit Method, giving eligible registrants two ways to reduce bookkeeping costs.

Who qualifies for the Quick Method?

Eligibility comes down to three main tests. Work through them in order.

1. Revenue threshold. Your worldwide taxable supplies (including those of any associated businesses) must not exceed $400,000 in the last four of five consecutive fiscal quarters, including GST/HST in that total. Exclude financial services, sales of capital assets, real property, and goodwill from the calculation.
2. Permanent establishment in Canada. You must have a permanent establishment here. A home office qualifies when it is your primary place of business.
3. Not an excluded registrant. RC4022 lists the registrants who cannot use the Quick Method, including:
   • Accountants and bookkeepers (including tax preparation firms)
   • Lawyers and notaries
   • Financial consultants and listed financial institutions
   • Charities and public institutions (separate rules apply)

New registrants can still elect in their first full year of business if they reasonably expect their worldwide taxable supplies and those of any associates to remain within the eligibility threshold. If you revoke the election, you must wait one full year before re-electing.

How do Quick Method remittance rates work across provinces?

The CRA’s RC4058 guide sets the remittance rates, and they vary along two dimensions: whether your permanent establishment is in a participating province (one that has harmonised its provincial sales tax with the federal GST to create HST) and whether your business is primarily service-based or goods-based.

The 40% goods threshold matters here. If at least 40% of your taxable supplies in the previous fiscal year were goods purchased for resale, you are treated as a goods/retail business and a different (generally lower) remittance rate applies.

Rates above are illustrative ranges only. Always confirm the current rate in RC4058 before filing, as rates can change and the CRA publishes effective dates for any revisions.

New Brunswick is a participating province, so if your permanent establishment is here, the participating-province rates apply to your remittance calculation. If you make sales in multiple provinces, the rate that applies depends on where your permanent establishment is located, though multi-province revenue can complicate rate selection and may warrant professional review.

How do you calculate your Quick Method remittance?

The formula is straightforward. According to the CRA’s calculation guidance:

Quick Method remittance = (taxable supplies including GST/HST) × remittance rate

You also subtract a 1% credit on the initial portion of eligible supplies in each fiscal year. That credit is easy to miss and worth including in every calculation.

Worked example for a New Brunswick freelancer

Suppose you are a freelance graphic designer based in Fredericton with the following figures for a quarterly reporting period:

• Revenue from taxable services billed: $20,000
• HST charged to clients at 15%: $3,000
• Total taxable supplies including HST: $23,000
• Applicable Quick Method remittance rate (service, participating province): 8.8%
• Gross remittance: $23,000 × 8.8% = $2,024
• 1% credit on first $30,000 (annual; assume this is the first quarter): $23,000 × 1% = $230
• Net remittance: $2,024 − $230 = $1,794

You collected $3,000 in HST but remit only $1,794, keeping $1,206 as a net benefit from using the Quick Method.

Spreadsheet formula (Excel or Google Sheets)

If your taxable supplies including HST are in cell B2 and your remittance rate is in cell B3, and the 1% credit base is in cell B4:

=(B2*B3)-(B4*0.01)

Keep a separate row for excluded supplies (such as zero-rated sales or sales of capital assets) and report those on your return under the regular method lines.

Reporting on your GST/HST return:

• Line 101: Total sales and other revenue (all taxable supplies including GST/HST)
• Line 103: GST/HST collected (your actual collected amount)
• Line 105: Total ITCs (under the Quick Method, this is generally zero for operating expenses, except for capital purchases)
• Line 113A / 113B: Quick Method calculation lines (net tax)

Pro Tip: Always separate excluded supplies before you apply the remittance rate. Applying the Quick Method rate to zero-rated sales or exempt supplies is one of the most common filing errors.

How do you elect or revoke the Quick Method?

The election is straightforward, but timing matters.

1. Obtain Form GST74. Download GST74 from the CRA website or access it through My Business Account or Represent a Client.
2. Choose your effective date. The election must take effect on the first day of a GST/HST reporting period. You cannot elect mid-period.
3. File the form. Submit GST74 to the CRA by the due date of the return for the period in which you want the election to begin. Online filing through My Business Account is the fastest option.
4. Confirm the election is active. Keep a copy of the filed form in your records.

Once elected, the Quick Method stays in effect until you revoke it or until a disqualifying event occurs (exceeding the $400,000 threshold or becoming an excluded registrant). If either happens, you must switch back to the regular method starting from the first day of the next reporting period.

Revocation rules by filing frequency:

• Annual filers: You can revoke effective the first day of any reporting period, but you must file the revocation by the due date of the return for that period.
• Quarterly or monthly filers: Same rule applies; the revocation takes effect on the first day of a reporting period.

After revoking, you must wait one full year before you can re-elect. For example, if a Moncton-based consultant revokes the election effective January 1, 2026, the earliest re-election date is January 1, 2027.

What records do you need to keep under the Quick Method?

The Quick Method reduces your ITC tracking, but it does not reduce your obligation to maintain proper records. The CRA expects you to retain supporting documents for a minimum of six years from the end of the last tax year to which they relate.

Keep the following:

• Sales records showing total taxable supplies for each reporting period, including the GST/HST component.
• Excluded supplies records: Any zero-rated, exempt, or excluded supplies must be documented separately, since they are reported differently on your return.
• Capital purchase receipts: You can still claim ITCs on capital property (equipment, computers, vehicles used in the business), so keep those invoices.
• GST74 election form: Retain a copy as proof of your election effective date.
• Annual revenue tracking: You need to monitor the $400,000 threshold on a rolling four-of-five-quarters basis, so keep quarterly revenue summaries.

Your filing frequency (monthly, quarterly, or annual) does not change under the Quick Method. What changes is the calculation method on your return, not how often you file. If you use T-Ledgers’ bookkeeping services, your records are maintained in a format that makes Quick Method reporting straightforward at filing time.

Is the Quick Method right for your business?

The honest answer depends on your expense profile. MoneySense notes that the Quick Method typically suits service businesses with low expenses but can be less profitable for expense-heavy or inventory-heavy businesses.

Reasons the Quick Method tends to work in your favour:

• You are a service-based business (consulting, design, writing, coaching) with few GST/HST-eligible expenses.
• Your actual ITCs on operating expenses are lower than the notional credit built into the remittance rate.
• You want to reduce bookkeeping time and filing complexity.
• Your revenue is well below the $400,000 threshold, giving you a comfortable buffer.

Reasons the regular method may be better:

• You purchase significant inventory or materials (the 40% goods threshold may shift your rate, but high ITCs may still exceed the Quick Method benefit).
• You have large eligible expenses (rent in a commercial space, equipment leases, significant professional fees) that generate substantial ITCs.
• You operate across multiple provinces, making rate selection complex.
• Your revenue is close to $400,000, increasing the risk of inadvertently exceeding the threshold.

Quick decision checklist:

• Are your taxable supplies $400,000 or less? If no, stop here.
• Is your profession excluded (accountant, lawyer, bookkeeper)? If yes, stop here.
• Do goods-for-resale represent 40% or more of your taxable supplies? If yes, use the goods rate, not the service rate.
• Are your actual ITCs on operating expenses likely to exceed the notional savings from the Quick Method rate? If yes, the regular method may save you more tax.

Pro Tip: Run a side-by-side comparison using one full year of your actual revenue and expense data before electing. A virtual CFO can model both methods and show you the net tax difference, including the 1% credit on the first $30,000 of eligible supplies, which is often overlooked in DIY comparisons.

Common mistakes to avoid when using the Quick Method

Most errors with the Quick Method fall into a small number of predictable categories. Knowing them in advance keeps you clear of reassessments.

• Misclassifying your profession. If you provide bookkeeping, accounting, or legal services, you cannot use the Quick Method even if your revenue is well under $400,000. The exclusion is profession-based, not revenue-based.
• Forgetting the 1% credit on the first $30,000. This credit applies annually to eligible supplies and reduces your remittance. Missing it means overpaying.
• Miscounting associated businesses in the $400,000 test. If you own or control associated businesses, their taxable supplies count toward your threshold. Treating each entity as independent when they are associated is a common audit trigger.
• Applying the Quick Method rate to excluded supplies. Zero-rated supplies (such as basic groceries or exported services) and exempt supplies must be reported separately under the regular method. Applying the Quick Method rate to them is incorrect.
• Wrong rate for multi-province sales. Your remittance rate is based on your permanent establishment’s province, but if you make significant sales in other provinces, the allocation can be more complex than a single rate suggests.
• Not reviewing eligibility at year-end. If your revenue grows close to or past $400,000, you need to switch back to the regular method. Missing this transition is a compliance risk.

Review your eligibility at the end of every fiscal year before filing the first return of the new year.

An editorial perspective on when the Quick Method actually makes sense

Most articles about the GST Quick Method present it as a straightforward win for small businesses. The reality is more nuanced, and the businesses that benefit most are a narrower group than the eligibility rules suggest.

The Quick Method genuinely shines for pure service businesses with minimal overhead: a freelance writer in Saint John, a web developer in Moncton, a consultant billing from a home office in Fredericton. For these businesses, the gap between what they collect in HST and what they would claim in ITCs is small, so the notional savings built into the remittance rate translate into real money kept and real time saved.

Where the method gets misapplied is with businesses that have meaningful expenses. A trades contractor who buys materials regularly, or a small retailer with inventory, often finds that their actual ITCs under the regular method exceed the notional benefit of the Quick Method rate. They elect the Quick Method because it sounds simpler, then discover at year-end that they overpaid.

The 1% credit on the first $30,000 of eligible supplies is genuinely underappreciated. For a very small business in its early years, that credit can offset a meaningful portion of the remittance. It should be in every comparison calculation, and it rarely is when business owners run the numbers themselves.

The other underestimated factor is multi-province revenue. A New Brunswick business that does significant work for clients in Alberta or British Columbia needs to understand how that affects rate selection. The rules are not impossible, but they are specific enough that a one-rate-fits-all approach creates errors.

The practical recommendation: do not elect the Quick Method based on a gut feeling that it is simpler. Run the numbers for one full year, include the 1% credit, and account for your actual ITC-eligible expenses. If the Quick Method saves you tax or time without costing you more than the bookkeeping savings are worth, elect it. If the numbers are close, the regular method gives you more flexibility.

FAQ

What is the Quick Method for calculating GST/HST?

The GST Quick Method lets eligible small registrants remit GST/HST by multiplying their total taxable supplies (including the GST/HST charged) by a set remittance rate, rather than tracking individual ITCs on expenses. The applicable rate depends on your province and whether your business is primarily service-based or goods-based.

Who cannot use the Quick Method for GST/HST?

Accountants, bookkeepers, tax preparation firms, lawyers, financial consultants, and listed financial institutions are excluded from the Quick Method regardless of their revenue level. See the exceptions section in RC4022 for the full list.

What is the HST rate in New Brunswick?

New Brunswick is a participating province with a combined HST rate of 15%. You still charge customers this full 15% rate under the Quick Method, only your remittance calculation changes.

How do I calculate GST/HST manually under the Quick Method?

Multiply your total taxable supplies including HST for the reporting period by your applicable remittance rate, then subtract the 1% credit on the first $30,000 of eligible supplies in the fiscal year. For example, $23,000 in taxable supplies at an 8.8% rate gives a gross remittance of $2,024, less a $230 credit, for a net remittance of $1,794.

Can a new business in New Brunswick use the Quick Method right away?

Yes, if you are a new registrant and reasonably expect your worldwide taxable supplies and those of any associated businesses to be $400,000 or less in your first full year, you can elect the Quick Method from the start. File Form GST74 with your first return or through My Business Account.
