Does a Service Business Charge Provincial Sales Tax? Which Taxes Apply

You have landed on a work permit, you have started doing freelance consulting or home-based services, and you are trying to figure out whether does a service business charge provincial sales tax in your case. A client asks, “Do I charge PST on this invoice?” The answer is: it depends on which province you are in, and what exactly you are charging for.

Canada’s provincial sales tax system is not one system — it is six different systems running in parallel. Some provinces tax services broadly. Others tax only goods. Some provinces have exemptions for professional services. Understanding your province’s rules before you invoice is the difference between an angry CRA audit and straightforward bookkeeping — and whether a service business charges provincial sales tax at all depends entirely on that province.

The six provincial tax systems

Alberta: No provincial sales tax at all. If you are doing business in Alberta, you charge no provincial tax. Federal GST (5%) applies to some services, but not all.

British Columbia: 7% PST (Provincial Sales Tax) applies to goods and most services, with exemptions. Professional services (accounting, legal, medical) are typically exempt. Labour-only services (plumbing, electrical) are taxable. Consulting is a grey zone — it depends on exactly what you are billing for.

Saskatchewan and Manitoba: 5% PST on goods; services are generally exempt unless specifically listed as taxable (vehicle repair, certain tradespeople). Professional services are typically exempt.

Ontario and Atlantic Provinces (except PEI): 13% HST (Harmonized Sales Tax — federal + provincial combined). HST applies broadly to goods and services, with exemptions for professional services (accounting, legal advice, medical). Labour-only services are taxable; consulting is often taxable.

Quebec: 5% GST (federal) + 9.975% QST (Quebec Sales Tax). Services are narrowly taxed compared to goods. Professional services are largely exempt.

Prince Edward Island: 14% HST (federal + provincial). Applies broadly with exemptions similar to Ontario.

What “service” means for tax purposes

This is where it gets genuinely blurry. A service provider might be charging for:

Expertise/advice (consulting, design, planning) — often exempt if it is professional advice.
Labour only (your time on a project, no materials) — often taxable.
Materials + labour (supplies + installation, such as plumbing or electrical work) — typically taxable on the full amount.
Arrangement/coordination (project management, brokerage) — varies widely by province.

Example: you are a software developer in British Columbia. If you invoice a client CAD $5,000 for “custom software development,” you might not charge PST (professional services exemption). If you invoice “labour for custom software development at CAD $100/hour for 50 hours,” you probably should charge PST (labour is typically taxable). The same work, two different tax treatments.

How to know for certain

The safest approach:

Consult your province’s tax authority or website — all have detailed guidance on which services are taxable.
Ask an accountant in your province — a 30-minute consultation costs CAD $100–200 and clarifies your obligations. It is money well spent if you are starting a business.
If you are unsure, charge the tax. It is easier to refund the customer if you over-charged than to ask them to pay additional tax later if you under-charged.

GST vs PST/HST: both apply

Do not assume that charging GST (federal, 5%) means you do not also charge provincial tax. In most provinces, both apply. In Ontario, you charge 13% HST (which includes both GST and Ontario’s provincial component). In BC, you charge 5% GST and 7% PST — both, on top of your service fee.

In Alberta, you charge 5% GST (federal) only — there is no provincial layer.

What small businesses often miss

Many newcomer service providers try to avoid the tax question by simply not charging it, or charging only GST federally. This is a mistake:

The CRA (Canada Revenue Agency) has authority over GST; provincial tax authorities have authority over PST/HST.
If you under-collect provincial tax and the tax authority audits, you owe the unpaid tax plus interest and penalties.
If you are registered for GST/HST but not properly tracking and remitting provincial tax, you have an incomplete tax picture.

Registration and collection

If your service business generates over CAD $30,000 in annual revenue, you must register for GST (federal). Provincial requirements for PST/HST registration vary — some provinces require registration above CAD $30,000; others have different thresholds. Once registered, you must collect and remit the tax on time.

Before you invoice your first client, register for the taxes you are obligated to collect in your province. It is free to register, and it keeps you compliant from day one.

The honest approach

Build the tax into your pricing from the start, clearly separate it on your invoices, and remit it on time. Customers expect to see tax itemised. Transparency builds trust and protects you if an audit ever happens.
