If you own a business in British Columbia, mark your calendar: October 1, 2026 is one of the biggest sales tax deadlines in recent provincial history. Under the BC PST changes announced in Budget 2026 and finalized in regulations released on July 9, 2026, the 7% Provincial Sales Tax (PST) is expanding to professional services — including bookkeeping and accounting services — for the very first time.
At RG Keepers Business Solutions, we help BC small businesses stay compliant and stress-free, so we’ve put together this plain-English guide to the BC PST expansion: what’s becoming taxable, what it means for your books, and exactly how to prepare before October 1.
Key takeaways:
- The 7% PST applies to accounting, bookkeeping, architectural, engineering, security, and non-residential real estate services starting October 1, 2026.
- Engineering, architectural, and geoscience services are taxed on 30% of the purchase price.
- PST exemptions are being removed for items like clothing repair materials, basic cable TV, and residential landlines.
- If you provide any newly taxable service, you must register on eTaxBC and begin collecting PST.
- Unlike GST/HST, PST has no general input tax credits — the PST you pay on business services is generally a real cost.
What’s Changing: The BC PST Expansion at a Glance
Historically, BC’s PST applied mostly to goods and a narrow list of services. Budget 2026 changed that. Effective October 1, 2026, the province is extending the 7% PST to several categories of professional services that were previously exempt, aligning BC more closely with PST-administering provinces like Saskatchewan and Manitoba.
The final regulations, published by the BC Ministry of Finance, confirm which services are taxable and how the tax is calculated — giving businesses a clear roadmap for compliance.
Which Professional Services Become Taxable on October 1, 2026?
Under the new rules, PST at 7% applies to:
- Accounting services, including bookkeeping and assurance services (taxed on the full fee)
- Architectural services
- Engineering and geoscience services
- Security services, including private investigation services
- Non-residential real estate services, including trading services, rental property management, and strata management services
That’s right — bookkeeping is now a taxable service in BC. If you outsource your books (even to us!), you’ll see PST added to your monthly invoices starting October 1.
The 30% Rule: A Special Case for Engineering, Architecture & Geoscience
Here’s where the rules get technical. For architectural, engineering, and geoscience services, PST applies to only 30% of the purchase price — not the full invoice.
For example, on a $10,000 engineering invoice, PST is calculated on $3,000, resulting in $210 of PST rather than $700. Your invoicing and accounting software must be configured to handle this partial-tax calculation correctly, or you risk overcharging clients or under-remitting to the province.
PST Exemptions Being Removed: Everyday Goods and Services Now Taxable
The BC PST changes don’t stop at professional services. Starting October 1, 2026, previously exempt goods and services become taxable, including:
- Clothing patterns, yarn, natural fibres, synthetic thread, and fabric used to make or repair clothing
- Clothing and footwear repair services (basic laundry services remain exempt)
- Basic cable television, toll-free telephone services, and residential landline services
If your business sells any of these items or services, you’ll need to update your point-of-sale systems and pricing accordingly.
What the PST Expansion Means for Your Business
1. You may need to register for PST — even if you never have before
Many professional service firms (bookkeepers, engineers, property managers, security providers) have never held a PST number. If you sell a newly taxable service on or after October 1, 2026, you’re required to register online through eTaxBC, charge PST, and file returns. Registration can take several weeks to process, so waiting until late September is a compliance risk.
2. PST is a “tax on a tax” — and it’s a real cost
Unlike GST/HST, BC’s PST does not offer general input tax credits. That means the PST your business pays on its own bookkeeping, accounting, or property management fees is generally not recoverable. It’s a genuine increase in your cost of doing business, and your budget and pricing strategy should reflect it.
3. Contracts spanning October 1 need review
If you have multi-month or multi-year agreements in place, services delivered or billed on or after October 1, 2026 are generally taxable — even if the contract was signed before the rules changed. Review your agreements now and clarify tax treatment with clients in writing.
Your Pre-October 1 PST Compliance Checklist
Use this checklist to get PST-ready:
- Audit your revenue streams. Identify which of your services fall into the newly taxable categories.
- Register on eTaxBC now. If you’re not registered, apply online as soon as possible — you can register up to six months before your first taxable sale.
- Update your invoicing and accounting software. Configure 7% PST on taxable services, including the special 30% calculation for engineering, architectural, and geoscience fees.
- Review open contracts and proposals. Add tax clauses or amendments addressing PST on post-October 1 billings.
- Revisit your pricing and budget. Factor in unrecoverable PST on the professional services you purchase.
- Notify your clients. Give customers transparent advance notice that invoices will include PST starting October 1.
- Tighten your record-keeping. Clean, well-coded books make PST filing — and any future audit — painless.

Frequently Asked Questions About the BC PST Changes
Is bookkeeping taxable under BC PST starting October 1, 2026?
Yes. Accounting services, including bookkeeping and assurance services, become subject to 7% PST on the full purchase price effective October 1, 2026.
Do I need to register for PST if my only taxable service is bookkeeping?
Yes. If you sell any newly taxable service in BC on or after October 1, 2026, you must register for a PST account online through eTaxBC, charge PST, and remit it to the province.
Is PST charged on the full invoice for engineering or architectural services?
No. PST applies to only 30% of the purchase price of architectural, engineering, and geoscience services.
Can I recover the PST I pay on my own bookkeeping or accounting fees?
Generally, no. BC’s PST does not provide general input tax credits like the GST/HST system, so PST paid on most business services is a final cost.
When should I register on eTaxBC?
As soon as possible. Businesses can register up to six months before their first taxable sale, and processing times can take several weeks — don’t leave it to the last minute.
