BC PST on Accounting Services: What Changes October 1, 2026

Will I have to pay PST on my accountant’s fees in BC? Yes. A 7% provincial sales tax applies to most accounting, bookkeeping, and tax services when the amount is paid or becomes due on or after October 1, 2026, on top of the 5% GST you already pay. Here is what that means for your next invoice and what you can still do before the deadline. AL Accounting is a Vancouver CPA firm helping BC businesses get ready for the October 1, 2026 PST change on professional services, with practical invoice-level guidance and updated engagement letters.

What’s changing on October 1, 2026?

BC is extending its 7% Provincial Sales Tax to accounting and related professional services, effective October 1, 2026. The change comes from Budget 2026 and Bill 2, the Budget Measures Implementation Act, 2026, which amends the Provincial Sales Tax Act. Final regulations released July 9, 2026 confirmed that the rules include tax advice, document preparation, and representation in tax disputes with the CRA. The province published Notice 2026-001 to alert providers and purchasers.

The PST stacks on top of the 5% GST you already see on accounting invoices. So a service that cost $500 plus $25 GST last year will carry an additional $35 PST once the rules kick in. The province projects this expansion will bring in over $260 million in the first six months and over $530 million in 2027/28. If you buy or sell accounting services in BC, this affects your cash flow, your quotes, and your software setup.

Which services are taxable, and which are still exempt?

PST applies to accounting, bookkeeping, payroll processing, tax return preparation, financial statement preparation, assurance services, and tax advice or representation in CRA matters. The definition is activity-based, not title-based. If your “consultant” actually does your books or payroll, that work is taxable even if the person is not a CPA. The government’s accounting services page makes this explicit: the rules apply “even if you’re not a Chartered Professional Accountant.”

Services that are NOT on the new taxable list include management consulting, IT services, marketing, HR consulting, and financial planning. Legal services were already subject to PST in BC under pre-existing rules; the October 1 expansion is about accounting and related professional services newly brought into the tax base. The distinction turns on what the person actually does for you, not their job title or firm name.

If you are unsure whether a specific engagement falls inside or outside the scope, ask your provider to confirm in writing. The safest approach is to review each service line on your recurring invoices and sort them into taxable and exempt columns before October.

When exactly does PST hit my invoices?

The transitional rule that trips most people: PST follows when consideration is paid or becomes due, not when the work was performed. If your accountant does the work in September but invoices you on October 1 or later, PST applies. If you prepay before October 1 for services that finish before December 1, no PST applies. The December 1 date is the backstop for the prepayment exemption.

Here are the three government worked examples translated into plain language:

The proration example matters for retainers and recurring engagements. If you pay $100 per month for a service running October through December, and the invoice went out September 15, PST applies only to the post-October-1 portion. That means $21 PST on $300 of taxable services. Review every active engagement letter and recurring billing schedule now to see where you land.

Can I save money by prepaying before October 1?

Yes, for services delivered through November 30, and the government’s own Example 1 confirms the approach. If you pay or your invoice becomes due before October 1, and all services under that invoice are completed before December 1, 2026, the entire amount is PST-free. You still pay the 5% GST, but you avoid the 7% PST on that batch of work.

The catch is that the prepayment must be genuine. You cannot prepay for a 12-month engagement in September and expect the full amount to escape PST. The exemption only covers services completed before December 1. Anything delivered on or after December 1 is prorated and the post-October-1 portion carries PST. Talk to your accountant about whether interim invoicing or pre-billing makes sense for your specific engagements. If you have a year-end engagement that wraps up in November, pre-billing before October 1 can legitimately save you 7%. If your engagement runs into January, only the pre-October-1 service portion is exempt.

How much more will accounting actually cost me?

Your total tax on accounting invoices goes from 5% to 12% after October 1. Unlike GST, there are no input tax credits for PST. You cannot claim PST back on your return. It is a sunk cost that compounds through your supply chain, which the BC Chamber of Commerce has flagged as a cascading cost issue for small businesses.

Here is the invoice math for two common engagements:

On a typical $500 monthly bookkeeping engagement, you pay an extra $35 per month, or $420 per year. On a $2,500 year-end, the PST adds $175. If you use AL Accounting’s bookkeeping services or corporate tax page, budget for roughly 7% more starting in October. The non-recoverability is the real sting. GST comes back through input tax credits on your return; PST does not. That means the 7% is a permanent cost increase, not a timing difference.

Do I or my provider need to register to collect PST?

If you provide taxable accounting services in BC, you must register to collect PST, even if you are not a CPA. Registration opened April 1, 2026 through the province’s eTaxBC portal. Processing takes up to 21 business days, so providers who have not yet registered need to move quickly. Small sellers with generally under $10,000 per year in taxable sales are exempt from registering, but only if they do not operate from established commercial premises. A firm with a commercial office does not qualify for the small-seller exemption regardless of revenue. Out-of-province providers who sell more than $10,000 in BC sales over a 12-month period must register.

On the purchaser side, if your provider does not charge PST where it is due, you may have to self-assess. This comes up most often when you use an out-of-province accountant who is not registered for BC PST. The obligation falls on you as the buyer to report and remit the tax. The government’s PST registration page walks through the steps. If you are unsure whether your current provider is registered, ask for their PST number before October 1. If they cannot provide one, confirm whether you will need to self-assess on future invoices. For AL Accounting’s GST/PST services, we already handle registration and remittance for clients who need it.

What should I do before October 1?

Run through this dated checklist to get your business ready. The window is short, but the steps are straightforward.

If you are a provider, your engagement letters should already say “plus applicable taxes.” AL Accounting has updated its engagement letter and quoting process to reflect this language. If your letters still say “plus GST,” change them now. The legally operative trigger is when consideration is paid or becomes due, but clear quote language prevents disputes later. Test your invoicing software with a sample October invoice to confirm the PST line calculates correctly on taxable services and does not apply to exempt ones.

FAQ

Can I avoid PST by prepaying my accountant before October 1?
Yes, but only for services completed before December 1, 2026. If you pay or your invoice becomes due before October 1 and all services under that invoice finish before December 1, the amount is PST-free. For engagements running into December or beyond, only the pre-October-1 service portion escapes PST. Talk to your accountant about whether pre-billing makes sense for your specific engagements.

My accountant did the work in September but invoiced me in October. Do I pay PST?
Yes. PST follows when consideration is paid or becomes due, not when the work was performed. If the invoice date is October 1 or later, the full amount is taxable even if the services were delivered in September or earlier. This is the transitional rule that catches most businesses off guard. Review your September work-in-progress billing schedule with your accountant before the deadline hits.

Is my consultant taxable too?
Only if the consultant actually performs accounting, bookkeeping, payroll, tax preparation, or assurance work. The definition is activity-based, not title-based. Management consulting, IT, marketing, HR, and financial planning are not on the taxable list. If your “consultant” does your books or tax returns, that work is taxable even without a CPA designation. Ask your provider to confirm in writing what services they deliver.

Can I claim PST back like GST?
No. Unlike GST, there are no input tax credits for PST. The 7% is a sunk cost that you cannot recover on your return. This is why the BC Chamber of Commerce has flagged the expansion as a cascading cost for small businesses. Budget for the increase as a permanent expense, not a timing difference. The GST portion remains recoverable through your usual input tax credit claim.

Do non-CPA bookkeepers have to charge PST?
Yes. The government explicitly states the rules apply “even if you’re not a Chartered Professional Accountant.” Any person or business providing taxable accounting services in BC must register and collect PST, regardless of professional designation. Small sellers under $10,000 per year in taxable sales are exempt from registering, but only if they do not operate from established commercial premises. A firm with an office does not qualify regardless of revenue. If your bookkeeper is unsure, point them to Notice 2026-001 and the eTaxBC registration page.

What if my accountant is outside BC?
If your out-of-province provider is not registered for BC PST and sells more than $10,000 of services to BC clients over a 12-month period, they must register and charge PST. If they do not, you as the purchaser must self-assess the tax. Place-of-supply rules generally look at whether the service relates to BC. Ask your provider for their PST number before October 1 to confirm whether you or they will handle the remittance.

Does PST apply to tax return preparation and CRA dispute help?
Yes. The July 9, 2026 final regulations confirmed that the rules include tax advice, document preparation, and representation in tax matters, including appeals, penalties, and interest disputes with the CRA. If your accountant helps you respond to a CRA notice or files a notice of objection after October 1, that work is taxable. Most content published before July 2026 misses this expansion.
