Yes. You can use the GST/HST Quick Method estimator below for a current reporting period. It is designed for an already-registered small business that uses the RC4058 service-business rate table. Enter one tax-included eligible-sales rate row and the tax band where the business has its permanent establishment (PE). A mixed-rate period needs RC4058’s 90% or multi-rate rules, so use the official guide for that case. For an ordinary invoice calculation instead, use the GST calculator.
Estimate one reporting period for a business using the service-business Quick Method table. This bounded version accepts one eligible supply-rate row only; it does not apply RC4058’s mixed-rate 90% or multi-rate rules. This is an estimate to check your return preparation, not an eligibility decision or a filed return.
This tool accepts only a whole period starting on or after 2025-04-01. It rejects earlier and straddling periods because Nova Scotia’s HST changed from 15% to 14% on that date. Read CRA Notice 342.
The supply rate and the PE band are separate RC4058 inputs. Selecting a rate here does not decide your legal place of supply.
Adjustments and comparison
The 1% credit is limited to the first $30,000 of qualifying eligible revenue in a fiscal year (maximum $300). Most operating-expense ITCs are already reflected in the Quick Method rates. Enter only an ITC you have independently established as eligible, such as one within RC4058’s capital-property rules.
Optional regular-method comparison. Use actual figures for the same reporting period; the calculator will not derive them from your sales rows.
Rules and rates: CRA Guide RC4058, retrieved 2026-10-20. The calculator excludes resale-business rates, 0% remittance-rate cases and related additional credits, point-of-sale rebate exceptions, non-eligible supplies, self-assessments, bad debts and other return adjustments. Check the official guide before filing.
Quick Method rates the calculator uses
RC4058’s service-business remittance rates are below, set by the GST/HST rate on eligible supplies and the tax band where the business’s permanent establishment (PE) is located. Find the row for the rate you collect and the column for your PE band to see the remittance rate before any credit.
| Rate collected on supplies | PE: 5% GST | PE: 13% HST | PE: 14% HST | PE: 15% HST |
|---|---|---|---|---|
| 5% GST | 3.6% | 1.8% | 1.6% | 1.4% |
| 13% HST | 10.5% | 8.8% | 8.6% | 8.4% |
| 14% HST | 11.3% | 9.6% | 9.4% | 9.2% |
| 15% HST | 12.0% | 10.4% | 10.2% | 10.0% |
Worked example: Ontario consultant
An Ontario-based consultant with a permanent establishment at the 13% HST band enters $56,500 in the 13% HST supplies row — $50,000 in service fees plus $6,500 of HST collected. RC4058 has you enter that total on line 101, rounded off to the nearest dollar; then apply the 8.8% service-table rate: $56,500 × 8.8% = $4,972 before credits. If the business qualifies for the 1% credit and has not used it yet this fiscal year, the credit is 1% of the first $30,000 of eligible revenue, or $300, giving an estimated net tax of $4,672. That is $1,828 less than the $6,500 actually collected, before any eligible capital-property ITCs. Enter the same figures into this GST Quick Method calculator to check your own period.
What this GST/HST Quick Method calculator estimates
The Quick Method is an accounting option for calculating GST/HST net tax. A registrant still charges the ordinary GST or HST rate on taxable supplies, then applies the applicable Quick Method remittance rate to tax-included eligible revenue. The applicable remittance rate can depend on both the rate on the supply and the business’s PE. CRA Guide RC4058 (retrieved 2026-10-20).
This estimator makes those two inputs visible, but it accepts only one supply-rate row. RC4058 has special 90% and multi-rate rules for a period with supplies in participating and non-participating provinces or different HST-rate groups; the estimator rejects a mixed entry rather than selecting a rule. It is also limited to the service-business rate table. A retailer or wholesaler whose goods-for-resale costs meet RC4058’s test uses a different table, including cases with a 0% remittance rate and a related credit; use the official guide for those cases rather than treating this result as universal.
Use only a current, whole reporting period
The calculator accepts a period that starts on or after April 1, 2025. It rejects earlier and straddling periods. Nova Scotia’s HST changed from 15% to 14% on that date, and the applicable rate for a transition can depend on when tax became payable or was paid. CRA Notice 342 (retrieved 2026-10-20) explains those rules.
What belongs in the sales rows?
Enter only tax-included revenue from supplies eligible for the Quick Method calculation. RC4058 lists supplies that are not eligible for that calculation, including zero-rated supplies, supplies made outside Canada, sales of real property and sales of capital assets. Those amounts need their own treatment on the return; leaving them out of the tool does not remove a reporting obligation. RC4058: supplies not eligible for the Quick Method calculation (retrieved 2026-10-20).
Quebec QST is not included. If a federal GST/HST calculation is appropriate for a Quebec transaction, the result is only that federal component; check the separate QST rules before relying on a total.
Why the 1% credit is optional in the tool
Include the 1% credit only if your business qualifies, and only for the part of the first $30,000 of eligible revenue not already used this fiscal year. See the Quick Method guide for the credit’s $30,000 revenue cap, timing conditions and its no-carry-forward rule. RC4058: 1% credit (retrieved 2026-10-20).
Quick Method versus the regular method
Quick Method rates already account for most operating-expense ITCs, so see the Quick Method guide for which capital-property purchases can still qualify separately. RC4058: claiming ITCs (retrieved 2026-10-20).
Check eligibility and make the election separately
A result is not a finding that the Quick Method election is available. See the Quick Method guide for the annual worldwide taxable-supplies test, associates and the business-activity exclusions RC4058 sets for eligibility. Review the Form GST74 election guide before using the method or filing a return.
