Frequently Asked Questions

Answers to your cross-border concerns

Everything you need to know about double taxation, US & UK obligations, and our
cloud-based tech stack.

Cross-Border & Double Taxation

I operate my business in both the US and the UK. Will my profits be taxed twice?
No, not if your accounting is structured correctly. The US and UK have a robust Double Taxation Convention explicitly designed to prevent this. The treaty determines which country has the “first right” to tax your specific business income, allowing you to claim Foreign Tax Credits (FTC) to offset your liability in the other country. We ensure your corporate structure takes full advantage of these protections so you never pay full tax twice on the same dollar or pound.

 

In the US, tax exposure comes down to two frameworks: Federal (Income Tax) and State (Sales Tax). Federal: Under the US-UK treaty, you generally aren’t subject to US federal income tax unless you have a Permanent Establishment (like a physical office, warehouse, or a dependent agent signing contracts) in the US. State Level: Physical presence doesn’t matter for Sales Tax. Ever since the landmark Wayfair decision, states can tax you based on Economic Nexus. If your remote sales into a single US state exceed their specific threshold (commonly $100,000 or 200 transactions annually), you are legally required to register, collect, and remit sales tax in that state.
If your UK business provides services to US companies, US tax law requires those payers to withhold a default 30% of your invoice value for the IRS. To stop this, you must give them a completed Form W-8BEN-E before they pay you. This form certifies to the IRS that you are a legitimate UK entity entitled to a 0% withholding rate under the US-UK tax treaty. We frequently handle the complex preparation of these forms to ensure your global cash flow remains uninterrupted.

Cloud Setup & Technology

How do you manage accounting software when my transactions span different currencies?
We build your digital infrastructure using multi-currency cloud platforms like QuickBooks Online or Xero. The software locks in live, daily foreign exchange rates, allowing you to invoice a client in USD, receive payments into a GBP bank account, and accurately track realized or unrealized currency gains automatically.
Yes. Because the UK operates under HMRC / UK GAAP rules and the US operates under IRS / US GAAP frameworks, each legal entity requires its own dedicated cloud accounting file to remain legally compliant. However, we leverage advanced reporting tools to seamlessly consolidate both accounts into a single, unified “global dashboard”—giving you a bird’s-eye view of your total business health in real-time.
