Important service notice
Tax and Accounting Hub is not currently able to provide Certifying Acceptance Agent (CAA) services. Our IRS Acceptance Agent authorisation is under renewal and we expect CAA document certification to resume in early 2027. Until then we continue to prepare, review and submit Form W-7 ITIN applications, and we will explain the document-certification options available to you (IRS Taxpayer Assistance Centre appointment, or certified copies issued by the passport-issuing authority) before you engage us.

What brings you here?
Four situations cover most of our UK-based clients. Pick the one closest to yours and we will take you to the right page.
UK resident with US income
Rental property, dividends, royalties or a US property sale. You need a Form 1040-NR and, in most cases, an ITIN.
1040-NR and ITIN →1040 + FBARUS expat living in the UK
Worldwide income still reportable to the IRS, plus FBAR and FATCA disclosure of your UK accounts and pensions.
US expat filing →W-7 + K-1UK member of a US LLC or LLP
Schedule K-1 income, withholding on your distributive share, and an ITIN before the partnership can report you.
ITIN for partners →1042-SReclaiming 30% US withholding
Authors, creators, musicians and casino winners. Treaty relief is claimed by filing — that is how the 30% comes back.
Reclaim withholding →Start here
Which describes you?
Two entirely different tax systems apply depending on whether you are a US person. Pick the wrong one and the return is wrong from line one.
I am a US citizen or Green Card holder
You are taxed on worldwide income wherever you live. You must file annually, report foreign accounts, and claim treaty and credit positions to avoid double taxation. If you are behind, Streamlined Filing is the route back.
US 1040 filing categories
I am not a US person but I have US income
You are taxed only on US-source income — but often at 30% of the gross amount, withheld at source before you see it. Filing is usually how you claim treaty relief, deduct expenses, and recover the difference.
1040-NR filing categoriesWhere we work
Two tax systems. Five locations.
We specialise in United States and United Kingdom tax, with our head office in London and representative support across the UAE, Singapore and India.
