Canadian Sales Tax by FSA

Sales Tax by Postal Code — How It Works

A Forward Sortation Area (FSA) is the first three characters of a Canadian postal code (in the format A1A). It represents a geographical area where all postal codes share the same three-character prefix. For example, M5V is the FSA for parts of downtown Toronto, while V6B covers Vancouver's central business district.

Canada Post divides the country into forward sortation areas for mail sorting and delivery. Each FSA corresponds to a specific region within a province or territory, making it possible to determine the applicable sales tax rate based on the first three postal code characters.

How to Calculate Sales Tax by Postal Code

To calculate sales tax for your location, you need to know the combined rate for your province or territory. The FSA tells you which province you're in, and the provincial rate structure determines the tax:

• GST Only (5%): Alberta, Northwest Territories, Nunavut, Yukon
• GST + PST: BC (12%), Manitoba (12%), Quebec (14.975%), Saskatchewan (11%)
• HST: New Brunswick (15%), Newfoundland (15%), Nova Scotia (14%), Ontario (13%), PEI (15%)

Anatomy of a Canadian Postal Code

Every Canadian postal code follows the format A1A 1A1 — a six-character alternating pattern of letters and numbers. Only the first three characters (the FSA) matter for sales tax, because they pin down the province or territory. The last three characters (the Local Delivery Unit, or LDU) narrow the address down to a block, building, or rural route and have no effect on the tax rate.

• 1st character (letter): the postal district — it maps directly to a province or territory (for example, every code starting with M is in Ontario, every V is in British Columbia).
• 2nd character (digit): urban or rural. A 0 means a wide rural FSA that serves an entire region; 1–9 means an urban FSA within a city.
• 3rd character (letter): a specific zone within that district.
• Last three characters: the exact delivery point — irrelevant to sales tax.

There are 1,666 tax-mapped FSAs in our database, spread very unevenly across the country: Ontario alone has 530, Quebec 422, and British Columbia 193, while Prince Edward Island has just 7 and each of the three territories has 3. Eight letters — D, F, I, O, Q, U, W and Z — are never used as the first character, because they are too easily confused with numbers or with each other when read by hand or scanned.

First Letter of a Canadian Postal Code by Province & Tax Rate

The single fastest way to know someone's sales tax rate is to read the first letter of their postal code. That letter alone identifies the province or territory — and therefore the 2026 GST/HST/PST rate. Here is the complete map:

Note: X is shared by the Northwest Territories and Nunavut, but both are GST-only at 5%, so the rate is identical. The letters D, F, I, O, Q, U, W and Z are not used.

Sales Tax in Major Canadian Cities (by FSA)

Because the rate is set at the provincial level, every neighbourhood in a given city pays the same combined rate. Here are the 2026 rates for Canada's largest urban centres, with a representative downtown FSA for each:

FSA Lookup Example

For Businesses: Destination-Based Sourcing

Critical for e-commerce and B2B sellers: Canadian sales tax is generally destination-based. This means you charge the rate based on your customer's delivery address, not your business location.

• Customer in Toronto (FSA M5V) → Charge 13% HST
• Customer in Vancouver (FSA V5K) → Charge 12% (5% GST + 7% PST)
• Customer in Calgary (FSA T2P) → Charge 5% GST only

Use the FSA lookup above for each customer's postal code to apply the correct rate automatically.

Provincial Deep-Dive: Tax Structures Explained

HST Provinces — Single Combined Rate (5 Provinces)

In Harmonized Sales Tax (HST) provinces, the federal government and province agreed to merge the 5% GST with the provincial sales tax into a single, combined rate. The Canada Revenue Agency (CRA) administers the entire HST, meaning businesses file one return and remit to one authority. This simplifies compliance significantly compared to dual-tax provinces.

• Ontario (13%): 5% federal + 8% provincial. Point-of-sale rebates on children's clothing, books, diapers, feminine hygiene products, and prepared food & beverages under $4.
• Nova Scotia (14%): 5% federal + 9% provincial. Point-of-sale rebates on books, children's clothing/footwear, diapers, and home heating fuel.
• New Brunswick (15%): 5% federal + 10% provincial. Point-of-sale rebates on books, children's clothing/footwear, and diapers.
• Newfoundland & Labrador (15%): 5% federal + 10% provincial. Point-of-sale rebates on printed books, children's clothing/footwear, baby diapers, and residential heating fuel.
• Prince Edward Island (15%): 5% federal + 10% provincial. Point-of-sale rebates on books, children's clothing/footwear, diapers, and residential heating oil.

GST + PST/QST Provinces — Dual Rates (4 Provinces)

These provinces maintain separate federal and provincial tax systems. The 5% GST is administered by CRA; the provincial tax (PST, QST, or RST) is administered by the province. Businesses must register separately, file separate returns, and calculate each tax independently on the purchase price (not compounded).

• British Columbia (12% — 5% GST + 7% PST): PST administered by BC Ministry of Finance. Remote sellers: $10,000 threshold for PST registration. PST is NOT recoverable as ITC — treat as business expense.
• Manitoba (12% — 5% GST + 7% RST): Retail Sales Tax (RST) administered by Manitoba Taxation. $10,000 threshold for remote sellers. RST not recoverable.
• Quebec (14.975% — 5% GST + 9.975% QST): Unique dual administration by Revenu Québec for both taxes. QST calculated independently on base (not on GST). QST recoverable via Input Tax Refunds (ITRs). Remote sellers: $30,000 threshold.
• Saskatchewan (11% — 5% GST + 6% PST): PST administered by Saskatchewan Ministry of Finance. No threshold for remote sellers — register from first sale. PST not recoverable.

GST-Only Territories — Federal Tax Only (4 Territories)

The three territories and Alberta do not levy a provincial sales tax. Only the 5% federal GST applies. This makes compliance simplest: one rate, one return (CRA), full ITC recovery. However, businesses selling into other provinces must still track destination-based obligations.

• Alberta (5%): Only province without PST or HST. Relies on resource revenues.
• Northwest Territories (5%): No territorial sales tax.
• Nunavut (5%): No territorial sales tax.
• Yukon (5%): No territorial sales tax.

Sales Tax for Online Sellers: Shopify, Amazon & Etsy

If you sell online into Canada, the postal code you ship to is the single most important field on the order. Because Canadian sales tax is destination-based, the correct rate is decided by the buyer's FSA — not by where your warehouse, your accountant, or your Shopify store happens to be. A $200 order to Toronto (M5V) carries $26.00 of HST; the identical order to Calgary (T2P) carries just $10.00 of GST. Same product, same price, different tax — entirely because of the postal code.

How the major platforms handle it

• Shopify: once you enter your GST/HST (and any PST/QST) numbers under tax settings, Shopify applies the destination province's rate automatically from the shipping postal code. You are still responsible for registering and remitting — Shopify only calculates.
• Amazon & other marketplaces: under Canada's marketplace-facilitator rules, large platforms are generally deemed the supplier and collect and remit GST/HST on third-party sales. Confirm what the marketplace collects on your behalf versus what you must remit yourself.
• Etsy: collects and remits Canadian GST/HST on many transactions as a facilitator, but sellers over the $30,000 threshold may still have their own registration and filing duties for direct/off-platform sales.

Selling into Canada from the US or abroad? Non-resident businesses must register for GST/HST once taxable sales to Canadian consumers cross $30,000 over any trailing 12-month period. Non-resident digital-product and platform sellers register under the CRA's simplified GST/HST regime, which uses the same $30,000 threshold. After that, you charge the destination province's rate by the customer's FSA, exactly like a domestic seller.

Compliance Checklist for Canadian Sellers

Whether you're a Canadian business or a foreign seller shipping into Canada, use this checklist to stay compliant:

1. Determine nexus: Physical presence, inventory storage, or economic threshold ($30,000 federal / province-specific thresholds) in a province triggers registration.
2. Register for tax accounts: Federal GST/HST via CRA Business Registration Online. Provincial PST/QST/RST via respective provincial portals (BC eTaxBC, Manitoba TAXcess, Revenu Québec, Saskatchewan eTax).
3. Apply destination-based rates: Use customer's delivery address FSA to determine the correct provincial rate. This tool makes that instant.
4. Separate tax on invoices: Show GST/HST and PST/QST as separate line items. In HST provinces, show the combined HST rate.
5. File returns on time: CRA assigns monthly/quarterly/annual frequency based on revenue. Provincial frequencies may differ.
6. Claim ITCs correctly: Federal GST/HST fully recoverable. Provincial PST/RST generally NOT recoverable (deduct as business expense). QST recoverable via ITRs.
7. Keep records 6+ years: CRA and provincial auditors require invoices with supplier Business Numbers, tax breakdowns, and dates.
