Why UK Crypto Traders & Web3 Founders Need a US LLC in 2026
Post-Brexit, UK SaaS companies scaling to the US face new banking and compliance friction with US enterprise clients. A US LLC provides a clean US billing entity, US bank account, and familiar W-9/1099 structure for US procurement teams.
Coinbase and Kraken issue W-9 requests and 1099-B for US account holders. Providing LLC EIN for exchange accounts means crypto gains/losses are reported to your LLC, not your personal SSN. NFT marketplaces (OpenSea) issue 1099-K at $5,000+.
On the banking side: GBP/USD exchange rate volatility (7–12% swings annually) reduces predictable USD revenue. Mercury USD accounts hedge this entirely for US-billed work. A Mercury USD account — accessible only with a US LLC and EIN — holds your Coinbase revenue in USD outside UK's banking system until you choose to convert on your own terms.
The Real Cost of Routing Revenue Without a US LLC
The $397 Year 1 LLC cost is recouped in ~2.2 months at $10,000/mo revenue from Payoneer fee savings alone — before counting Stripe access, treaty withholding reduction, or enterprise contract access.
Coinbase, Kraken, Gemini, and regulated US exchanges require W-9 for US persons. Providing LLC EIN means exchange tax reporting goes to your LLC. OpenSea and other NFT platforms issue 1099-K at $5,000+ in transaction volume. A Wyoming LLC provides the EIN that satisfies this requirement — protecting your personal SSN from every platform relationship and keeping business and personal tax identities cleanly separated.

Payment Stack for UK Crypto Traders & Web3 Founders
Stripe
Available in UKStripe UK is excellent — but UK founders serving US clients often prefer US LLC Stripe accounts for USD billing, US acquiring rates, and avoiding GBP conversion friction on USD revenue.
Mercury Bank Account
Free · FDIC $5M · No minimumMercury welcomes UK founders with standard approval — typically 3–5 business days after EIN.
Mercury requires: Wyoming LLC Articles (Doola provides), IRS EIN CP575 letter, and your United Kingdom passport.Coinbase payouts deposit to Mercury via ACH at $0 cost on the platform's standard schedule.
Wire fees work one direction only: sending USD from Mercury to your United Kingdom bank account costs $20 flat per wire (no percentage). Platform → Mercury is always free. Minimize wire costs by accumulating funds in Mercury and batching into larger, less-frequent transfers — e.g. one $10,000 monthly wire costs $20 vs four $2,500 bi-weekly wires costing $80.
PayPal
Full access in UKPayPal UK is fully functional. US LLC PayPal is useful for founders who want to hold USD reserves without GBP conversion.
Tax Position: UK Crypto Traders & Web3 Founders
US–UK Tax Treaty: 15% Withholding Rate (vs 30% default)
The comprehensive US-UK tax treaty reduces dividend withholding to 15% and royalty withholding to 0% (on most royalty types). The 0% royalty withholding is exceptional — UK-based IP holders licensing to US companies pay no withholding on those royalties. File W-8BEN to claim.

Form 5472: The $25,000 Penalty Every UK LLC Owner Must Avoid
Every foreign-owned US single-member LLC — including United Kingdom-owned Wyoming LLCs — must file Form 5472 annually. The IRS automatic penalty for non-filing is $25,000 per year per form, regardless of whether the LLC had any revenue. New LLCs with zero income in their first year still owe the filing.
Year 1 trap: Paying the Doola formation fee from your personal funds counts as a capital contribution to the LLC — a reportable transaction under Form 5472. Even a $0-revenue LLC that only received its initial funding must file. Founders who skip this "because we had no revenue" are the ones receiving $25,000 IRS notices.
Doola's Tax & Compliance plan ($1,999/yr) includes Form 5472 preparation and filing — the most common compliance gap for international founders.
US Crypto Exchange Access with Your UK LLC
Major US crypto exchanges (Coinbase, Kraken, Gemini, Binance.US) require US entity verification for business accounts with higher withdrawal limits and institutional features. Your Wyoming LLC provides this verification — no US residency required.
Business Account Limits
Coinbase Pro: $1M+ daily withdrawal limit (vs $10,000 personal). Kraken Pro: unlimited with enhanced verification. Business accounts unlock OTC desk access for large trades with reduced slippage.
KYC Requirements for LLC
Exchange business verification requires: (1) Wyoming Articles of Organization, (2) EIN CP575 letter, (3) Operating Agreement naming you as member, (4) Your passport as beneficial owner. Doola provides all LLC documents.
MiCA Regulation & Your US LLC
Under EU MiCA (effective 2024), United Kingdom crypto traders face increasing local exchange compliance requirements and potential asset restrictions. A US LLC with a US Coinbase/Kraken account operates under US regulatory jurisdiction — separate from MiCA obligations. You still owe United Kingdom tax on worldwide crypto gains; the LLC provides platform access and USD liquidity outside the EU framework.
UK Banking Context
GBP/USD exchange rate volatility (7–12% swings annually) reduces predictable USD revenue. Mercury USD accounts hedge this entirely for US-billed work.
