Our approach
Built for the cross-border edge cases.
Most US-UK filings fail the same way: a treaty position that wasn’t disclosed, a foreign account that slipped under FBAR thresholds, a PFIC election filed in the wrong year, a carry-forward not tracked from one preparer to the next. The cost of any single one of those is rarely catastrophic on its own — it’s the compounding over multiple filing seasons that quietly turns a clean tax life into a six-figure remediation project.
We start every engagement by looking at the edge cases first — the elections, the disclosures, the carry-forwards, the side-effects on next year’s return — and only then turn to the routine line items. The result is a filing that reads cleanly to anyone who picks it up next: another preparer, the IRS, or a successor in your own business.
- Position memo on every meaningful election, with the reasoning written down for the next return
- Carry-forwards (FTC, capital losses, PFIC basis) tracked year-on-year so nothing expires unused
- Plain-English commentary on every position taken — the kind that makes a future audit a non-event

FAQs
Common questions about LLC tax returns
Is my single-member LLC reported on my personal return?
By default yes — on Schedule C (active trade/business) or Schedule E (rental activity). Check-the-box elections (Form 8832) can change that to partnership or corporate treatment.
Do I pay self-employment tax on LLC profits?
US-resident members typically yes (Schedule SE — 15.3%). UK-resident members covered by the US-UK Totalisation Agreement usually no, provided you hold a Certificate of Coverage from HMRC.
What about state franchise taxes?
Most US states charge an LLC filing fee or franchise tax. California's $800 minimum catches everyone; Delaware has a $300 franchise tax. State rules vary widely and add complexity for multi-state LLCs.
Can my UK partner receive K-1s from a US LLC?
Yes if the LLC is taxed as a partnership. The UK partner would also file 1040NR or have tax withheld via Form 8804/8805 depending on income character. Cross-border LLCs need coordinated US/UK reporting.
