About three minutes · no documents needed
Check what may need a closer look.
Answer one broad question at a time. Don’t enter tax IDs, exact amounts, addresses, precise travel dates or free text.
About three minutes. No email, documents or exact amounts required. Preliminary only—not tax advice. This public check does not prepare or file a tax return.
Step 1 of 4: US–UK connection
Answers stay only in this browser tab. Going back preserves them; refreshing starts over. This diagnostic does not calculate tax, determine an obligation or promise filing support.
What the preliminary map covers
The map keeps possible US federal, UK, state and local, US–UK treaty, and separate reporting areas distinct. It labels each area as something that may apply, needs more information, or cannot be assessed reliably from these answers.
It does not calculate tax, decide residence, determine a filing obligation, check a deadline, or confirm that Treaty can support a filing. Any later service would begin by checking your facts and explaining exactly what it can cover.
If you cannot use the questions, you can still read the public guidance without providing answers, an email address, documents, or exact amounts.
