B.C. PST professional services calculator 2026.

Estimate the new B.C. PST on one confirmed taxable accounting, architecture, engineering, geoscience, security, or non-residential real estate amount. Preserve the Province’s 7%-on-30% formula and screen the October 1 transition without uploading invoice data.

Published calculation bases

One 7% rate, two purchase-price bases.

The Province applies 7% to the taxable purchase price for three groups and 7% to an amount equal to 30% of the taxable purchase price for architecture, engineering, and geoscience. The calculator keeps those two steps visible.

Service group	Published PST calculation	C$100 example
Accounting, bookkeeping, and assurance	7% × taxable purchase price	C$7.00
Architectural services	7% × (30% × taxable purchase price)	C$2.10
Engineering and geoscience services	7% × (30% × taxable purchase price)	C$2.10
Security and private-investigation services	7% × taxable purchase price	C$7.00
Non-residential real estate services	7% × taxable purchase price	C$7.00

October 1 transition

The first paid-or-due date and December 1 service boundary both matter.

Run one invoice, retainer, or milestone at a time. The calculator does not infer when consideration became due or allocate work across dates.

When consideration is paid or due	When services are provided	Calculator path
Before October 1, 2026	Entirely before December 1, 2026	No PST under the published transition pattern
Before October 1, 2026	Any services on or after December 1, 2026	Apply the group formula only to consideration attributable to services on or after October 1
On or after October 1, 2026	Before or after October 1	Apply the group formula to the confirmed taxable purchase price unless an exemption applies

Worked arithmetic

Three results the calculator keeps distinct.

C$100 taxable accounting service

7% × C$100 = C$7.00 PST. The displayed purchase price plus PST is C$107.00; federal GST remains separate.

C$100 taxable engineering service

7% × (30% × C$100) = C$2.10 PST. The 2.1% equivalent is arithmetic, not a different statutory rate.

C$40 post-October attribution

For a pre-October architectural amount spanning December, 7% × (30% × C$40) = C$0.84 PST when C$40 is the documented post-October attribution.

Use one bounded calculation

Calculate only after the legal treatment is confirmed.

01
Choose the official service group and enter one purchase-price amount.
02
Enter the first date that consideration was paid or became due for that amount.
03
Confirm taxable, confirmed no-PST, or needs-review treatment; the tool stops when taxability is unresolved.
04
For pre-October consideration, confirm the December 1 boundary and enter any documented post-October attribution.
05
Save the calculation with the contract, classification, exemption, allocation, invoice, and registration evidence.

Definitions, exemptions, fees, disbursements, B.C. connection, registration, transition rules, and electronic filing differ by service. The calculator intentionally does not compress those legal tests into one yes-or-no question.

Questions before the number

Six boundaries this calculator will not guess.

Does selecting a service group prove that PST applies?

No. Each group has definitions, B.C.-connection rules, exemptions, resale treatment, fees, disbursements, and registration facts. Select confirmed taxable only after those facts are reviewed.

Is the rate 2.1% for architecture and engineering?

The Province publishes a 7% PST rate applied to an amount equal to 30% of the taxable purchase price. C$100 therefore produces C$2.10, but 2.1% is the equivalent arithmetic result rather than a separate statutory rate.

What date should I enter?

Enter the first date the consideration for that invoice, retainer, or milestone was paid or became due. Use separate calculations when different amounts have different dates.

What if an invoice issued before October covers work after November?

The published transition pattern can apply PST to consideration attributable to services provided on or after October 1 when any covered services are provided on or after December 1. The tool requires you to enter, not invent, that allocation.

Does the B.C. small-seller exception use the GST/HST C$30,000 test?

No. B.C. PST small-seller treatment is a separate provincial analysis. The calculator does not substitute the federal GST/HST threshold.

Does the result include 5% GST?

No. The result is a PST-only estimate. Federal GST taxability, place of supply, registration, invoice treatment, and rounding remain separate.

Educational scope

A calculation is not a taxability or registration decision.

This educational tool estimates PST only after the visitor supplies the service group, purchase price, first paid-or-due date, confirmed taxability, and any transition allocation. It does not determine professional definitions, property classification, B.C. connection, exemptions, small-seller status, resale, bundled supplies, disbursements, self-assessment, registration, filing, invoice requirements, or GST. Confirm material or unusual facts with the Province or a qualified adviser.
