Understanding the UK Side: Zero-Rating Your Exports
Before you worry about the IRS in America or the CRA in Canada, you need to handle your UK obligations. When you export goods from the UK to a country outside the UK and EU, those sales are generally zero-rated for VAT.
This means you do not charge 20% VAT to your American or Canadian customers. However, you must keep thorough evidence of the export: such as commercial invoices and shipping documents: to prove the goods left the country. Failing to maintain these records could lead to HMRC demanding the VAT you didn’t charge.
You should also ensure your VAT invoices are correctly formatted for international trade. For more on managing your local obligations, check out our UK tax tips to run your business accounting.
Navigating the USA: It’s Not VAT, It’s Sales Tax
The biggest shock for UK sellers entering the US market is the lack of a federal VAT. Instead, the USA uses a Sales Tax system managed at the state and local levels. There are over 11,000 different tax jurisdictions in the US, each with its own rates and rules.
What is Nexus?
In the US, your obligation to collect and remit sales tax is triggered by “Nexus.” Nexus is a connection between your business and a state.
- Physical Nexus: Having an office, employees, or inventory in a warehouse (like Amazon FBA) in a specific state.
- Economic Nexus: Reaching a certain threshold of sales or transactions in a state (e.g., $100,000 in sales or 200 transactions in a calendar year).
Once you trigger Nexus, you must register for a Sales Tax Permit in that state and start collecting tax from customers. Don’t worry; we handle the registration and ongoing filings for you, so you don’t have to keep track of 50 different state deadlines.
Marketplace Facilitator Laws
If you sell via Amazon, eBay, or Walmart, your life is slightly easier. Most US states have “Marketplace Facilitator” laws. This means the marketplace collects and remits the sales tax on your behalf. However, you may still have a requirement to register and file “zero-returns” in certain states to stay fully compliant.
Cracking the Canadian Code: GST, HST, and PST
Canada’s system is a hybrid that feels a bit more familiar to UK sellers but has its own traps. Canada uses three types of sales taxes:
- GST (Goods and Services Tax): A 5% federal tax applied nationwide.
- HST (Harmonized Sales Tax): A combined federal and provincial tax (usually 13% or 15%) used in provinces like Ontario and New Brunswick.
- PST/QST (Provincial Sales Tax): Separate provincial taxes applied in provinces like British Columbia, Saskatchewan, and Quebec.
The $30,000 Threshold
Generally, if your worldwide revenues stay below $30,000 CAD in a single calendar quarter or over four consecutive quarters, you may be considered a “small supplier” and might not need to register for GST/HST immediately. However, once you cross that threshold, registration is mandatory.
Being a Non-Resident Importer (NRI)
Many UK sellers choose to act as a Non-Resident Importer (NRI). This allows you to clear goods through Canadian customs in your own company name. It simplifies the process for your customers because they won’t be hit with unexpected duties or taxes upon delivery. Working with ecommerce accountants who understand NRI status is vital to ensure you aren’t overpaying on import duties.
Comparing the Two: USA vs. Canada Tax Compliance
| Feature | United States (Sales Tax) | Canada (GST/HST/PST) |
|---|---|---|
| Tax Level | State and Local (No Federal) | Federal and Provincial |
| Registration Trigger | Physical or Economic Nexus | Exceeding $30,000 CAD threshold |
| Marketplace Collection | Widely handled by platforms | Mixed (Some GST handled, PST varies) |
| Filing Frequency | Monthly, Quarterly, or Annually | Monthly, Quarterly, or Annually |
| Tax Type | Consumption tax (no input credits) | Value-added tax (input tax credits available) |
How to Maintain Compliance Without Losing Your Mind
Expanding internationally shouldn’t mean spending forty hours a week on spreadsheets. The key to successful cross border VAT and sales tax management is automation and expert execution.
- Centralize Your Data: Use a system that pulls data from your Shopify, Amazon, or eBay stores directly.
- Monitor Your Thresholds: You need to know the moment you are about to hit an economic nexus in California or the GST threshold in Canada.
- Register Early: Don’t wait until you’ve already made thousands of dollars in sales to register. Retroactive tax bills often come with heavy penalties.
- Partner with Professionals: Trying to DIY US sales tax is a recipe for a compliance headache.

Why You Need an Ecommerce Accountant UK for Global Growth
If you are a UK-based business, you need an ecommerce accountant who understands both local HMRC rules and international requirements. You don’t want a traditional accountant who only looks at your year-end accounts; you need a compliance partner who understands the daily pace of digital sales.
Managing cross-border expansion involves more than just tax. It’s about understanding how your UK bookkeeping integrates with your US sales tax filings. It’s about knowing when to register for GST in Canada to claim back the tax you paid on your inputs.
