QuickBooks Online B.C. PST setup for engineering: 7% on 30% plus GST (2026)

Start with the expected C$1,071 invoice, not a software label

For a confirmed C$1,000 taxable engineering service connected to B.C., the Province's formula produces C$21 of PST: 7% × (30% × C$1,000). If the federal facts separately support 5% GST on the C$1,000 fee, the illustrative tax lines are C$50 GST and C$21 B.C. PST, for a C$1,071 total.

That expected output is the acceptance test. A tax-code name, a combined percentage, or a green software status does not prove that the invoice, liability accounts, tax report, credit workflow, and return all preserve the same result.

Confirm the engineering-service definition, B.C. connection, exemption, resale treatment, disbursements, allocation, collector or small-seller position, first paid-or-due date, and GST treatment before configuring the software. This guide starts only after those legal facts are confirmed.

Reject the ordinary 12% GST/PST BC code for this fee

Intuit's current Canadian common-code table lists GST BC at 5%, PST BC at 7%, and GST/PST BC at 12%. That ordinary 12% code is designed for a transaction where both taxes apply to the full net amount. It does not express the Province's reduced engineering PST base.

On C$1,000, the ordinary 12% code would produce C$50 GST and C$70 PST, for C$120 of tax. The confirmed engineering example requires C$50 GST and C$21 PST, for C$71 of tax. The ordinary code would overstate PST and the invoice total by C$49.

Do not fix that error by entering one undifferentiated 7.1% tax. The 7.1% total is only the arithmetic sum of an illustrative 5% GST component and a 2.1% engineering PST equivalent. The invoice and books still need to identify the statutory taxes, agencies, and liabilities separately.

Create the 2.1% component under the B.C. PST agency only as a tested candidate

Intuit's current QuickBooks Online Canada instructions distinguish a fully custom tax from a custom rate added under an existing sales-tax agency. They warn that a fully custom tax code does not report to federal or provincial tax agencies. For this workflow, that makes agency mapping an explicit gate rather than a naming detail.

In the current web instructions, start in All apps, Sales Tax, Overview, then Manage sales tax. Confirm that the B.C. provincial agency exists. Under that existing agency, use Add custom rate if the feature is available in the company's tax model and plan. Give the candidate a dated, auditable name such as “BC PST ENG — 7% × 30% — 2026-10-01” and enter 2.1% only as the arithmetic equivalent for a fully taxable engineering purchase price.

Do not change the ordinary 7% PST rate, reuse a code already attached to historical transactions, or call 2.1% the statutory rate. If the company file offers only a fully custom tax that bypasses the B.C. agency, or the custom component does not reach the expected provincial liability and report, stop and obtain current Intuit or accounting support before using it.

• Capture the QuickBooks plan, tax model, company province, agency name, code name, component rate, effective date, and setup date.
• Keep the separate workpaper showing 7% × 30% beside every invoice that uses the 2.1% implementation component.
• Apply the component only to a line whose entire net amount is a confirmed taxable engineering or geoscience purchase price.
• Use separate lines or supported allocations for exempt work, other service groups, goods, software, actual-cost exclusions, credits, and transition amounts.

Build a group rate only when both components apply to the net amount

Intuit's current Canadian group-rate instructions allow existing tax rates to be combined and let the user choose whether the second component applies to the net amount, tax amount, or net plus tax amount. For the C$1,000 acceptance example, both the 5% GST component and the 2.1% engineering PST component must calculate from the confirmed C$1,000 net amount—not from one another.

A candidate group can therefore combine the existing 5% GST code with the tested 2.1% B.C. engineering PST component, with both applicable on the net amount. Use a transparent name such as “GST 5% + BC PST ENG 7%×30%” rather than “7.1% tax.” If GST does not apply to the transaction, do not use the group merely to obtain the PST component.

QuickBooks interfaces and plan capabilities can change. Treat the current menu path as a starting point, then inspect the generated invoice preview, PDF, sales-tax detail, liability accounts, credit memo, and return workflow. The setup is rejected if the software collapses both components into an unidentified total or posts either component to the wrong agency or account.

Run invoice, PDF, credit, rounding, and mixed-line tests before sending

Section 85 of the Provincial Sales Tax Regulation requires a collector who provides an invoice and levies PST to show that tax as a separate item. Print or save the customer-facing PDF and confirm that the B.C. PST amount is identifiable apart from GST. A correct backend split does not cure a customer document that only says “7.1% tax” or “sales tax C$71.”

Run at least the C$1,000 baseline, a larger invoice, a credit, a cents-sensitive amount, and one mixed or allocated invoice. Compare every result to the free Thirty North calculator and the saved 7%-on-30% workpaper. Do not test by emailing a live customer; use a draft or clearly fictional test record and remove it according to the company's controls.

A C$12,000 fully taxable engineering purchase price produces a C$3,600 PST calculation base and C$252 PST. If 5% GST separately applies to the full fee, the illustrative GST is C$600 and the total is C$12,852. A C$100 credit should reverse C$5 GST and C$2.10 PST when it reverses the same confirmed treatment.

Reconcile QuickBooks to Box A, Box B, and the B.C. PST payable

The Province's return guide says Box A contains total taxable, non-taxable, and exempt Canadian sales and leases for the period, excluding GST and PST. Box B contains the total PST collectable on taxable sales and leases, including PST charged even if it has not yet been collected. Sellers of the newly taxable professional services must file and remit electronically.

Intuit's Canadian guidance directs users to review the tax centre and a sales-tax liability or taxable-sales report before filing, then file with the tax agency and record the payment in QuickBooks. For the C$1,000 test, verify that the invoice contributes C$1,000 to the appropriate sales total, C$21 to the B.C. PST amount, C$21 to the B.C. PST payable, and no part of that C$21 to revenue or the GST payable.

Do not assume a 2.1% report column is sufficient. Reconcile the invoice list, credits, QuickBooks tax report, B.C. PST payable register, Box A workpaper, Box B workpaper, eTaxBC return, and payment. Keep a manual bridge if QuickBooks reports the full engineering fee at a 2.1% component while the internal legal workpaper must show 7% × 30%.

Keep transition, bundles, exemptions, and GST outside the shortcut

The 2.1% component is valid arithmetic only when the entire coded amount is a confirmed taxable engineering or geoscience purchase price. It cannot classify the service, choose an exemption, allocate a mixed contract, exclude actual-cost travel, determine a B.C. connection, or decide small-seller or registration status.

For the October 2026 transition, the first date consideration is paid or becomes due and the December 1 service boundary can change the amount subject to PST. Use separate invoice lines or calculations for retainers, milestones, September work billed in October, pre-October consideration spanning December, and credits. Never apply the custom component to the full contract when only an attributed part is taxable.

GST remains a separate federal conclusion. The examples in this guide use 5% GST only to test a common B.C. invoice when that federal treatment has already been confirmed. They do not decide registration, place of supply, zero-rating, exemptions, input tax credits, or the GST base for another engagement.

Use a fail-closed go-live checklist and preserve the software evidence

Approve the setup only when the legal classification, invoice display, component arithmetic, agency mapping, liability accounts, reports, credits, return bridge, and payment workflow all pass. Record who reviewed the test, the QuickBooks plan and interface date, the code names, screenshots or PDFs, reports, expected results, observed results, corrections, and approval date.

If QuickBooks cannot produce a separately identified PST item and the required reporting path, pause automated sending. Use a reviewed invoicing workflow that can meet those requirements and have a qualified bookkeeper, accountant, Intuit support representative, or the Province confirm the unresolved implementation. Do not disguise PST as a service line or revenue item merely to make the total equal C$1,071.
