The 1099-K Threshold: The End of “Under the Radar” Selling
For years, the IRS planned to lower the reporting threshold for Form 1099-K from $20,000 to just $600. After several delays and “transition periods,” the 2026 tax year marks the full implementation of stricter reporting requirements.
If you sell on platforms like Amazon, eBay, or Shopify, or if you accept payments via PayPal and Stripe, these third-party settlement organizations (TPSOs) are now required to report your gross proceeds to the IRS much more aggressively.
Why this matters for international sellers:
- Data Matching: The IRS uses automated systems to match the 1099-K data sent by payment processors with your tax filings. If there is a discrepancy, it triggers an automatic flag.
- Increased Scrutiny on Foreign Entities: Even if you are a non-US resident selling through a USA LLC, the IRS is looking closer at “effectively connected income” (ECI).
- No More Minimum Transaction Count: Previously, you needed 200 transactions to trigger a report. That safeguard is gone. One large sale or many small ones, it all counts.
Economic Nexus: The Rules Are Getting Local
While the IRS handles federal income tax, you cannot ignore state-level Sales Tax. By early 2026, nearly every US state has refined its “Economic Nexus” laws. You no longer need a physical warehouse or office in a state to owe taxes there. Simply reaching a specific sales volume (often $100,000 or 200 transactions, though some states have removed the transaction count) makes you liable.
The 2026 Shift in State Compliance
Many states are now moving toward “Destination-Based Sourcing” for all digital products and services, not just physical goods. If you sell SaaS, digital downloads, or remote consulting to US clients, you may have a Sales Tax registration requirement you didn’t have two years ago.
Action Item: Conduct a Nexus study. If you cross the threshold in a state like Texas or California, you must register, collect, and remit sales tax. Failure to do so can lead to back taxes and penalties that wipe out your profit margins.
The Corporate Transparency Act (CTA) and Beneficial Ownership
If you use a USA LLC to facilitate your sales, the Corporate Transparency Act is now in full swing. This isn’t strictly an “IRS” update, but it is a federal requirement that the IRS uses for cross-referencing.
Most “reporting companies” (including most small LLCs used by international sellers) must report their Beneficial Ownership Information (BOI) to FinCEN.
- Who is a Beneficial Owner? Anyone who exercises substantial control over the company or owns at least 25% of it.
- The Penalty: Failure to report or updating late can result in civil penalties of up to $500 per day and even criminal charges.
For international entrepreneurs, this means the “anonymity” of certain US states (like Wyoming or Delaware) is effectively over for compliance purposes. Transparency is the only way forward.
Marketplace Facilitator Laws: The “Hands-Off” Trap
Many sellers believe that because Amazon or Walmart “collects and remits” sales tax under Marketplace Facilitator laws, they are 100% compliant. This is a dangerous misconception in 2026.
The Compliance Gaps:
- Income Tax vs. Sales Tax: Amazon handles the Sales Tax at the point of sale, but they do not handle your federal or state income tax obligations.
- Inventory Presence: If you use FBA (Fulfillment by Amazon), your inventory moving between warehouses can create “Physical Nexus,” which might trigger additional filing requirements like franchise taxes or personal property taxes.
- Direct Sales: If you sell even one item through your own website (Shopify/WooCommerce) to a state where you have nexus, you are responsible for that tax, not the marketplace.
Maintaining healthy cash flow management requires accounting for these hidden tax liabilities before they become a crisis.
Streamlining Your US Compliance Checklist
Don’t let the complexity paralyze your growth. Follow this checklist to ensure your US expansion remains profitable and legal:
- Apply for an EIN: If you haven’t already, ensure your foreign entity or US LLC has a Federal Employer Identification Number.
- Monitor Thresholds Monthly: Track your sales by state. Don’t wait until the end of the year to realize you crossed a nexus threshold in October.
- Separate Business and Personal Finances: This is the #1 mistake international sellers make. Use a dedicated business account.
- Implement Robust Bookkeeping: The IRS requires “contemporaneous” records. You cannot recreate your books three years later during an audit.
- File Form 5472 and 1120: If you have a foreign-owned US Disregarded Entity (LLC), these forms are mandatory. The penalty for failing to file Form 5472 is currently $25,000.
