Our approach
US business filings that fit the UK reality.
A US LLC, partnership or corporation owned or run from the UK sits between two systems that rarely line up — distributions, basis, and the credit for UK tax paid all have to be reconciled, and a US corporation with foreign shareholders brings its own reporting (Forms 5472, 1120-F) that is easy to miss.
We prepare the US business return with the UK side in view from the start, track basis and distributions so they are not taxed twice, and make sure any inbound-reporting obligations are met rather than discovered in an IRS notice.
- US and UK treatment of distributions and basis reconciled, not assumed
- Owner-level and entity-level filings prepared as one coherent set
- Inbound reporting (5472 / 1120-F) checked for US entities with foreign owners
