Zamp Extends Its Fully Managed Sales Tax Service to Canada

U.S. businesses selling into Canada can rely on the same end-to-end sales tax service they trust across all U.S. states, Canadian provinces, and territories, now available in every Canadian province, with Zamp continuing to own every outcome.

NEW YORK--(BUSINESS WIRE)--Zamp today announced that its fully managed sales tax service now covers Canada end-to-end. U.S. businesses selling into Canada can rely on the same service they trust across all U.S. states, Canadian provinces, and territories: exposure tracking, registration, filing and remittance, and notice management across every Canadian province and territory — with Zamp shouldering the accountability at each step in the process.

Canada is one of the first international markets U.S. businesses expand into, and one of the most underestimated for compliance. The GST/HST registration threshold is just CAD $30,000 in worldwide revenue, a low bar that catches U.S. sellers early, often before they realize they have a tax obligation. From there it gets harder, GST/HST federally, PST in British Columbia, Manitoba, and Saskatchewan, and QST in Quebec. Separate regimes, separate registrations, separate filings. Most U.S. businesses are not equipped to manage that alone.

This service expansion came directly from Zamp's customers. Many of the businesses Zamp already serves had expanded into Canada and wanted the same hands-off compliance they get domestically. Zamp calculated Canadian tax for them for years. Now, Zamp also manages the entire sales tax compliance lifecycle across Canada, built the same way Zamp builds everything – own the data, own the workflow, own the result.

"Our customers asked for Canada, so we built it. Hundreds of the businesses we serve are already selling there, and they deserve the same thing we give them at home: we do the work, and we stand behind every filing. That's true across all U.S. states, Canadian provinces, and territories. Starting today, it's true in every Canadian province — and it's another step in taking the fully managed model internationally," said Rohit Bhadange, CEO and Founder of Zamp.

Zamp covers every Canadian province and territory across every tax regime: GST/HST nationwide, PST in British Columbia, Manitoba, and Saskatchewan, and QST in Quebec. Zamp tracks exposure, handles registration, prepares and files returns, and remits on the customer’s behalf. The service is available as a flat annual fee with no per-province or per-filing charges. Zamp's accounting partners can offer the same fully managed service to their own clients as well.

Canada is the first market outside the U.S. where Zamp manages the entire process — from calculation to initial exposure through registration, filing, remittance, and notice management. It is a significant milestone for Zamp’s global platform expansion strategy and is the model Zamp will bring to more markets as U.S. businesses keep expanding abroad.

"Zamp's expanded Canadian tax compliance capabilities are a game-changer, giving our Canadian and U.S. merchants a single, fully managed solution to handle domestic and cross-border tax compliance with confidence," said Spiro Khouri, Senior Partnerships Manager at Ecom North.

Zamp has remitted over $330 million in sales tax, completed more than 100,000 on-time filings, and maintained 99.97% filing accuracy since launch. The company's accounting firm partner network spans 140+ firms, including Baker Tilly, Eide Bailly, Withum, Anchin, Frank Rimerman and Larson Gross, with 97.8% client retention. Canada extends that infrastructure — the same team, the same model, the same accountability — beyond US borders for the first time in the company's history.
