Nunavut GST Guide

Nunavut charges only the 5% federal GST with no territorial sales tax. Combined rate of 5% — tied for the lowest in Canada. Businesses deal only with the CRA for all sales tax matters.

Fly into Iqaluit on a clear morning and the first thing you notice after the tide flats is how little paperwork stands between a business and its customers here: Nunavut is one of only four Canadian jurisdictions that charges nothing but the federal 5% GST, with no territorial sales tax layered on top. A soapstone carving sold out of a co-op in Cape Dorset, a sealift container of building supplies landing in Rankin Inlet, or a claim-stage gold exploration contract near the Meliadine or Hope Bay properties all face the same single number: 5%. There is no provincial sales tax return to file, no separate registration with a territorial revenue office, and no second set of rules to reconcile against the federal ones, because Nunavut's government has simply never created a territorial sales tax.

That simplicity matters more in Nunavut than almost anywhere else in the country. This is Canada's largest and least populated territory, spread across 25 fly-in communities with no road or rail connection to the rest of Canada and almost everything — from groceries to mining equipment to art supplies — arriving by sealift in the short summer shipping season or by air year-round. A gold mine, a fishing co-op, or an Inuit art gallery already absorbs enough logistics complexity without also having to track a provincial sales tax base, exemptions, and a separate filing calendar. The 5% GST is administered entirely by the Canada Revenue Agency (CRA), so one registration, one return, and one payment channel cover the whole picture.

The practical upshot is that Nunavut is tied with Alberta, Yukon, and the Northwest Territories for the lowest sales-tax burden in Canada, and every dollar of that 5% GST paid on legitimate business inputs is fully recoverable through input tax credits (ITCs) for registrants. This guide walks through why the territory has no sales tax of its own, how to register and file GST correctly, how to work through a real ITC recovery example, and how the rules apply to remote sellers, digital products, and Nunavut's signature industries — gold and iron ore mining, commercial fishing, Inuit arts and crafts, and tourism.

Nunavut was created in 1999 and, like its two northern counterparts, never introduced a territorial sales tax. The territorial government funds its programs mainly through federal transfer payments, resource royalties, and personal and corporate income tax rather than a general consumption tax on goods and services. With a population spread across dozens of small, isolated communities and a cost of living already elevated by freight and fuel costs, layering a second sales tax on top of the 5% GST was never adopted as territorial policy.

That means every taxable sale in Nunavut — retail goods in Iqaluit, hotel stays in Rankin Inlet, professional services delivered by phone or video from the south, hardware shipped in on the sealift — carries only the 5% federal rate. There is no Nunavut sales tax number, no territorial exemption certificate, and no territorial audit function running in parallel with the CRA's. Businesses that also operate in Ontario, Quebec, or the Maritimes will notice immediately how much lighter the compliance load is once their Nunavut operations are the only thing on the books.

The 5% GST itself applies broadly: most goods, most services, restaurant meals, hotel rooms, equipment rentals, and professional fees are all taxable at the standard rate unless a specific exemption or zero-rating applies. Basic groceries, most health care, and residential rent remain GST-exempt or zero-rated everywhere in Canada, Nunavut included — the territory doesn't carve out any additional exemptions of its own because it has no tax base to carve them from.

Because there is no territorial tax authority, registration is a single federal step through the CRA. Any business or individual carrying on a commercial activity in Nunavut — including sole proprietors, corporations, partnerships, and non-resident vendors selling into the territory — must register once worldwide taxable revenue exceeds $30,000 CAD over four consecutive calendar quarters. This is the same federal small-supplier threshold that applies everywhere in Canada; Nunavut does not adjust it up or down.

Below that $30,000 threshold, you're considered a 'small supplier' and registration is optional. Many Nunavut sole proprietors — an artist selling carvings directly, a part-time guide, a small charter operator — stay under this line and simply don't charge GST. The moment cumulative revenue over a rolling four-quarter window crosses $30,000, registration becomes mandatory, and it's worth tracking that number closely if your business has seasonal spikes tied to tourism season or sealift-driven project work.

Registration itself runs through CRA Business Registration Online (BRO), by phone, or by mail, and results in a Business Number (BN) with an RT program account extension (e.g., 123456789RT0001) that covers your GST/HST obligations. Practical steps: gather your legal business name, structure (sole proprietor, partnership, or incorporated), estimated annual revenue, and fiscal year-end; apply through BRO or by calling the CRA business inquiries line; receive your BN and RT account, typically the same day online; then start charging 5% GST on taxable supplies from your effective registration date and issuing proper invoices that show the GST amount and your BN.

• $30,000 CAD over four consecutive quarters is the mandatory registration threshold — same as everywhere in Canada
• Registration is federal only: one Business Number, one RT program account, no territorial counterpart
• Small suppliers under $30,000 may register voluntarily to claim ITCs, which is common for capital-intensive startups
• Non-resident and remote vendors selling into Nunavut use the same $30,000 threshold under the digital economy rules

The CRA assigns your GST filing frequency based on annual taxable supplies, and this schedule is identical whether your business is based in Iqaluit or Toronto — Nunavut has no separate filing calendar to track. Businesses with $1.5 million or less in annual taxable supplies file annually by default (though monthly or quarterly is available on request); those between $1.5 million and $6 million file quarterly; and those above $6 million must file monthly. Annual filers with a December 31 fiscal year-end owe their return, and any balance, by June 15 of the following year, but if a balance is owing it still has to be paid by April 30 — an easy trap for annual filers to miss.

Quarterly filers report and remit within one month of each quarter's end, and monthly filers within one month of each month's end. Given Nunavut's reliance on the sealift season for major purchases — hardware, vehicles, and building materials often arrive in one summer window — many businesses find quarterly reporting keeps large ITC claims closer to when the GST was actually paid, rather than waiting for an annual return.

All filing runs through CRA My Business Account, GST/HST NETFILE, or a registered tax preparer; paper filing is discouraged and, for larger filers, not permitted. Payment can be made electronically through CRA My Payment, online banking bill-payment (most Canadian banks list 'CRA GST/HST' as a payee), pre-authorized debit set up in My Business Account, or wire transfer for those without a southern bank branch nearby. Because Iqaluit and the smaller communities don't have in-person CRA counters, electronic filing and payment aren't just convenient in Nunavut — for most businesses they're the only realistic option.

This is where Nunavut's tax structure genuinely pays off for registered businesses. Because there is no territorial sales tax component sitting on top of the GST, there's nothing 'stuck' the way a non-recoverable provincial tax can be in some other jurisdictions — the entire 5% GST paid on eligible business inputs is recoverable as an input tax credit, provided the input relates to your commercial activity and you hold a proper invoice showing the supplier's GST/HST number.

Take a concrete example: a construction contractor in Rankin Inlet orders a sealift shipment of lumber, fasteners, and heavy equipment parts totalling $80,000 before tax, plus $4,000 in 5% GST charged by the southern supplier. On the same return period, the contractor also pays $6,000 plus $300 GST for a barge freight invoice covering delivery, and $12,000 plus $600 GST for a subcontracted excavation crew. Total GST paid on inputs: $4,000 + $300 + $600 = $4,900. If the contractor billed clients $150,000 for the season and collected $7,500 in GST on those sales, the net GST remittance to the CRA is $7,500 collected minus $4,900 in ITCs, leaving $2,600 payable — every dollar of the $4,900 paid out on freight, materials, and labour comes straight back rather than being absorbed as a cost.

Eligible ITC categories in Nunavut mirror the rest of Canada: commercial rent, sealift and air freight charges, fuel, heavy equipment and vehicle purchases or leases, professional fees, office and shop supplies, subcontractor costs, and inventory for resale all qualify, with meals and entertainment restricted to 50%. For purchases under $100 including GST, you can claim the ITC without the supplier's BN printed on the receipt, which helps with small cash purchases in communities where formal invoicing is less common. Keep every sealift bill of lading and freight invoice — with input costs this geographically inflated, ITCs on transportation alone can be a material recovery for northern businesses.

Nunavut's remote geography makes it a heavy consumer of goods and services shipped or streamed in from elsewhere, so the federal digital economy and place-of-supply rules matter as much here as the local ones. A non-resident digital business — a SaaS company, a streaming service, an online retailer with no physical presence in Canada — must register for and charge 5% GST once its sales to Canadian customers, including those in Nunavut, exceed $30,000 over four consecutive quarters. That $30,000 threshold is federal and territory-blind; it doesn't matter whether the customers are in Iqaluit or Ottawa.

For place-of-supply purposes, the rate charged is determined by the customer's location, not the seller's. A business in Manitoba shipping goods to a customer in Arviat charges 5% GST, because Nunavut has no provincial component to add — the same invoice sent to a customer in Winnipeg would carry 5% GST plus 7% Manitoba PST if PST applied to that good. Nunavut-based sellers shipping to customers in HST provinces need to charge the destination province's HST rate on B2C sales where those rules apply, which is one of the few areas where a Nunavut business needs to look beyond its own 5% rate.

Sealift and air freight carriers moving goods into Nunavut charge GST on their freight services just like any other taxable supply, and that GST is recoverable by a registered business receiving the shipment as a normal input tax credit — it isn't a separate 'import tax' requiring special customs-style handling for domestic interline shipments. Inuit art and craft sales follow the same rule as any other taxable supply: a carver, printmaker, or textile artist selling directly is GST-taxable once registered, but stays outside the system entirely as a small supplier below $30,000, which describes a large share of individual Nunavut artists. Co-ops and galleries that exceed the threshold must charge GST on sales, including sales shipped south to buyers in other provinces, since the tax follows the seller's registration status and the destination rules, not where the piece was carved.
