Check current HST rates by province.

The Rate You Charge Depends on Where the Customer Is

I was sitting in my office last Tuesday, staring at a receipt for a single box of paperclips that had been scribbled on with a leaking ballpoint pen, when it hit me: most business owners are losing sleep over the wrong things. They spend hours obsessing over tiny supply costs while completely tripping over the current hst rates by province because they assumed “tax is just tax.” Let me tell you, if you’re operating across the border of Ontario and New Brunswick, that assumption is a fast track to a CRA penalty you didn’t see coming.

I’m not here to give you a lecture or a dense, academic breakdown that reads like a legal textbook. My goal is to give you the straight talk I wish my clients had heard three years before they ended up in my office with a mountain of unfiled paperwork. I’m going to lay out exactly what these rates look like right now, where the provincial math gets tricky, and how to make sure you aren’t leaving money on the table simply because you didn’t know which rule applied to your specific corner of Canada.

A Harmonized Sales Tax by Province List Youll Actually Use

I’ve spent enough time staring at spreadsheets to know that nobody wants to memorize a tax table. You just want to know what to charge the customer sitting in front of you so you don’t end up owing the CRA a chunk of your profit come quarter-end. Most people get tangled up in a gst vs hst comparison, thinking it’s a different beast entirely, but it’s really just about how the provinces decided to play ball with the federal government.

If you are operating in Ontario, New Brunswick, Newfoundland and Labrador, Nova Scotia, or PEI, you’re dealing with the full harmonized rate. For example, in Ontario, you’re looking at a flat 13%. However, if your business touches the West or the Prairies, the math changes because they haven’t fully “harmonized” everything. You’ll be dealing with a mix of the federal GST plus a separate provincial component. This harmonized sales tax by province list isn’t just academic; if you apply the wrong rate because you assumed everyone followed Ontario’s lead, you’re the one left holding the bag during an audit.

The Combined Sales Tax Rates Canada What Youre Really Paying

Here is the reality: when you look at your invoices, you aren’t just seeing one number. You’re seeing a cocktail of different tax layers. Most people get tripped up trying to do a manual gst vs hst comparison in their heads, but it’s simpler than that. In provinces like Ontario or the Maritimes, you’re dealing with a single, unified rate where the federal and provincial portions have been mashed together. In other places, like BC or Alberta, you’re dealing with the standard GST plus a separate provincial tax that hits your customers differently.

The reason this matters for your cash flow is that the combined sales tax rates Canada uses can vary significantly depending on exactly where your business is registered and where your customers are sitting. You can’t just pick a flat percentage and hope for the best. If you’re miscalculating that total amount on your outgoing invoices, you’re essentially playing a high-stakes game of chicken with the CRA. Get the math right now, or you’ll be spending your next tax season explaining to me why your books don’t match your bank statements.

Five Ways to Keep the CRA From Taking More Than Their Fair Share

  • Stop treating HST like it’s “your” money. When you collect that tax from a customer, it’s already gone; you’re just holding it in trust for the government. If you treat it like part of your revenue and spend it on a new piece of equipment, you’re going to have a very stressful conversation with me come tax season.
  • Watch your province of supply. If you’re an Ontario-based consultant selling to a client in Nova Scotia, you don’t get to use your local rate. You use the rate where the service is actually provided. It sounds simple, but I’ve seen plenty of shoeboxes filled with errors because people just applied their home province’s rate to everything.
  • Don’t forget your Input Tax Credits (ITCs). This is where most small business owners leave money on the table. Every cent of HST you pay on legitimate business expenses—from your office supplies to your professional fees—is something you can claim back. If you aren’t tracking those receipts, you’re essentially giving the government a tip they didn’t ask for.
  • Be careful with “mixed” supplies. If you sell a product that has both taxable and exempt components, you can’t just pick the easier rate. The math gets messy quickly, and if you guess wrong, the CRA won’t care that you were trying to be efficient.
  • Set up a separate savings account specifically for your HST remittances. Every time a client pays an invoice, move the tax portion into that account immediately. It keeps your operating cash flow clean and ensures that when the filing deadline hits, the money is actually there.

The Bottom Line: Three Things to Stop Worrying About

Stop trying to memorize every single rate; just remember that if you’re in the Maritimes, you’re looking at 15%, and if you’re in Ontario, it’s 13%.

Always collect the rate based on where your customer is located, not where your office is, or you’ll end up with a math headache come tax season.

Keep your sales and tax collected in separate columns in your bookkeeping—mixing them together is the fastest way to realize you’ve accidentally spent the CRA’s money.

The Bottom Line on Your Sales Tax

At the end of the day, navigating the patchwork of HST and GST across the provinces doesn’t have to be a headache, provided you stop treating it like a guessing game. We’ve covered the rates, we’ve looked at how they shift depending on whether you’re in Ontario or the Maritimes, and we’ve identified where the math actually hits your bottom line. The most important takeaway is this: don’t wait until tax season to realize you’ve been applying the wrong rate to a client in a different province. Keep your records clean, understand your specific provincial obligations, and stop leaving your compliance to chance. A little bit of organization now saves you from a very expensive conversation with me—or the CRA—later.

I know that when you started this business, you had a vision for a product or a service, not a desire to become an expert in provincial tax jurisdictions. It feels like a distraction because, frankly, it is. But once you get these basics down and build a repeatable system for tracking your rates, the tax side of things stops being a source of anxiety and starts being just another routine part of your operations. You built this company to create something meaningful, not to chase receipts. Get your tax math sorted, get it out of your head, and get back to doing the work that actually matters.

Frequently Asked Questions

If I'm selling my services to a client in a different province, which rate am I actually supposed to charge them?

This is the question that keeps me up at night, usually right before a curling tournament. Here’s the rule: you charge the rate based on where your customer is located, not where you sit in your home office. If you’re in Ontario but your client is in Nova Scotia, you charge the NS rate. It feels backwards, but the CRA wants the tax collected where the service is actually consumed. Just keep your client’s address on file so you aren’t guessing.

I already collect GST—do I need to do anything special to start collecting HST in the Maritimes?

If you’re already collecting GST, you’re halfway there, but don’t assume the transition is automatic. Since you’re moving into a province that uses HST, you need to update your registration with the CRA to reflect the harmonized rate. It’s usually a simple administrative tweak to your existing account, but you must ensure your invoicing reflects the correct combined rate immediately. Don’t wait until filing season to realize you’ve been undercharging; that’s a headache nobody needs.

Does the rate change if I'm selling digital products or professional services versus physical goods?

The short answer is: no, the rate itself doesn’t change, but the “is it taxable?” part is where people trip up. Whether you’re shipping a box of widgets, selling a downloadable PDF, or billing for a consulting hour, the HST rate stays the same. The trap is assuming digital products are exempt like some books are—they usually aren’t. If it’s a taxable supply, you charge the full rate. Don’t overcomplicate it; just keep your records straight.
