A US LLC and a UK Ltd, kept clean on both sides.
You run a US LLC and a UK Ltd side by side — founder-owned, or a small group. Two sets of filings, and an LLC's US tax treatment doesn't map neatly onto how the UK sees it.
The LLC mismatch nobody warned you about
A US LLC is often fiscally transparent for US tax, while the UK may treat it as opaque — a classic mismatch that can cause double taxation or lost foreign tax credits for the owner. Add two sets of accounts, two corporation tax positions and intercompany flows, and it needs one team who sees both.

The things founders ask first
Why does my LLC cause a UK tax problem?
Because the US and UK can classify it differently — transparent versus opaque — which can mean the same profit is taxed in a way that doesn't line up, and credits get lost. We resolve how yours is treated for you specifically.
Do the two companies need transfer pricing?
If they trade with each other, usually yes — both HMRC and the IRS expect arm's-length pricing. We set an intercompany policy that satisfies both.
Can you do both sets of accounts?
Yes — US and UK bookkeeping, accounts and filings from one team, which is the whole point of not splitting it across two firms.
