Understanding the US Substantial Presence Test

The US substantial presence test determines if you’re a US tax resident. It hinges on how many days you’ve spent in the States over a three-year period. Let’s simplify:

• 31 days minimum in the current year.
• 183 days total over three years, calculated as:
• 100% of days in the current year.
• 1/3 of days in year one before the current year.
• 1/6 of days in year two before the current year.

Example time:
You were in the US 120 days in 2023, 2024 and 2025. For 2025:
– 120 days (full count for 2025)
– 40 days (1/3 of 120 from 2024)
– 20 days (1/6 of 120 from 2023)

Total? 180 days. You miss the 183-day threshold by just three days. No US residency under the substantial presence test for 2025.

Exceptions and Exempt Individuals

Some days simply don’t count:

• Commuting daily from Canada or Mexico.
• Transit stays under 24 hours.
• Crew members on foreign vessels.
• Medical emergencies that trap you in the US.
• Individuals on certain A, G, J, M or Q visas.

If you exclude days, you must file Form 8843. Otherwise Uncle Sam won’t recognise your carve-outs.

Navigating UK Residency Rules for Innovator Visa

UK Innovator Visa rules don’t tally days in the same way. Instead, focus on:

• Continuous residence: You must not spend more than 180 days outside the UK in any 12-month period.
• Home Office compliance: Provide passport stamps, travel itineraries and utility bills.
• Endorsement body standards: Show proof of genuine innovation, viability and scalability.

Key points to remember:

• You can’t split your time like the US substantial presence test.
• Missing stamps or documents? That’s a red flag.

To stay organised, track your travel in a simple spreadsheet or diary. You’ll thank yourself later.

Key Differences: US vs UK Residency Criteria

Here’s where the two systems diverge:

1. Counting Days
   – US substantial presence test uses weighted days over three years.
   – UK Innovator Visa cares about any 180-day absence in a rolling year.

2. Documentation
   – US relies on Form 8843 and travel logs.
   – UK demands proof of residence, business plan and endorsement letters.

3. Legal Status vs Tax Status
   – US test determines tax residency.
   – UK rules determine visa endorsement and legal stay.

4. Grace Periods
   – US offers closer connection exceptions for students and diplomats.
   – UK has limited flexibility once you breach the 180-day rule.
