Master USA Compliance: LLCs, IRS Reporting, and Sales Tax
The United States is often the first stop for global expansion, but it also has some of the most rigorous reporting requirements for foreign owners. If you operate through a US LLC, you must stay on top of federal and state-level obligations.
Secure Your Standing with IRS Form 5472
If you own a single-member US LLC as a non-US resident, the IRS views your entity as a “Foreign-Owned Disregarded Entity.” While you might not owe federal income tax if you have no US-sourced income, you are required to file Form 5472 and a pro forma Form 1120.
- The Deadline: For the 2025 tax year, these are typically due by April 15, 2026.
- The Penalty: Failure to file this informational return carries a staggering $25,000 fine.
Doing this correctly ensures your LLC remains in good standing and avoids unnecessary legal headaches.
Navigate the Sales Tax Nexus Maze
Since the Wayfair decision, physical presence is no longer the only trigger for US Sales Tax. You now have to worry about Economic Nexus. Most states require you to register and collect sales tax once you exceed a specific threshold, usually $100,000 in sales or 200 transactions into that state.
Keep this in mind:
- Monitor your sales: Track your revenue state-by-state to identify when you are approaching a threshold.
- Register early: Once you hit the limit, you must register and begin collecting tax from your customers.
- Marketplace Facilitators: If you sell on Amazon or Walmart, they often collect tax for you, but you may still have state reporting obligations.
Don’t Forget BOI Reporting
Starting in 2024 and continuing through 2026, the Beneficial Ownership Information (BOI) report is a mandatory filing with FinCEN. This is separate from the IRS and requires you to disclose who truly owns and controls the company. Register your BOI within 30 days of forming a new entity to avoid civil and criminal penalties.
Conquering Canada: GST/HST for Non-Resident Sellers
Canada’s tax system is structured yet accessible if you know the thresholds. For international sellers, the primary focus is the Goods and Services Tax (GST) and Harmonized Sales Tax (HST).
Understand the $30,000 CAD Threshold
In 2026, the magic number for Canada remains $30,000 CAD. If your taxable sales to Canadian customers exceed this amount over four consecutive calendar quarters, you must register for GST/HST.
Two ways to register:
- Standard Registration: Best if you store goods in a Canadian warehouse (like Amazon FBA Canada). This allows you to claim Input Tax Credits (ITCs) on the tax you pay at the border.
- Simplified Regime: Designed for cross-border digital services and platform-based sellers who do not have a physical presence or inventory in Canada.
The Benefit of NRI Status
Being a Non-Resident Importer (NRI) allows you to act as the importer of record. This simplifies the process for your customers because they won’t be hit with unexpected tax and duty bills upon delivery. Maintaining an NRI status builds trust and improves the customer experience, which is essential for repeat business.
Dominating Australia: GST and the ABN Essentials
Australia is a lucrative market, but its “connected with Australia” rules for GST are unique. Whether you are shipping from abroad or using local warehouses, you need to understand your footprint.
The $75,000 AUD GST Trigger
Non-resident businesses must register for GST if their annual turnover in Australia reaches or is expected to reach $75,000 AUD.
- Low-Value Goods: If you sell items valued under $1,000 AUD directly from your website, these sales count toward your threshold.
- Marketplace Exception: If you sell only through a marketplace like Amazon AU, and they collect the GST at checkout, those sales generally do not count toward your $75,000 registration limit.
Simplified vs. Standard GST
If you are just starting and shipping from overseas, Simplified GST is often the easiest path. You won’t need an Australian Business Number (ABN), and reporting is straightforward.
However, if you plan to store stock in Australia (FBA AU), you must obtain an ABN and use Standard GST registration. This is essential because it allows you to reclaim the GST you pay on imports and local Amazon fees. To avoid late payment fines and ensure compliance, it is essential to set this up before your first shipment arrives.
Your Cross-Border Compliance Checklist for 2026
To ensure you stay ahead of the curve, follow this structured approach to global compliance:
- Check Thresholds Monthly: Don’t wait until the end of the year. Use accounting software to track your “nexus” in the US and turnover in Canada and Australia.
- Maintain Records: Keep all import documentation, invoices, and digital receipts for at least five years.
- Register Proactively: If you know a big marketing push will push you over a limit, register for VAT/GST/Sales Tax in advance.
- Partner with Experts: Cross-border tax is complex. Using a service like Sterlinx Global ensures your filings are accurate and submitted on time.
