Two tax specialists said my return all hinged on the Statutory Residence Test, and one wanted £500 just to answer my questions. This tool cleared up every definition and let me model exit dates and exactly how many UK days I had left. I'd happily have paid more for it, and I cancelled the £500 meeting.
I bought your tool simply because the gov.uk page for split year treatment is very complicated to navigate… It gives an evaluation of my situation in a matter of minutes and it is clear how the tool arrives at the evaluation.
The dashboards are the only interactive tools I came across that shed light on split year treatment and residency status based on HMRC parameters. I can highly recommend this tool.

Day Budget Dashboard

Adjust every SRT variable and see your residence status update in real time. Know exactly how many days you can spend in the UK before triggering residence.

  • Real-time day budget with proximity alerts
  • Toggle ties on/off to see impact instantly
  • Full residence matrix - every days/ties combination
  • Automatic test summary and deeming rule calculator

Adjust any variable - your residence status updates in real time.


Split Year Treatment Dashboard

Leaving or arriving in the UK mid-year? The split year dashboard works through all 8 HMRC cases and tells you exactly which one applies, your split date, and what you need to evidence.

  • All 8 HMRC cases evaluated with priority resolution
  • Split date calculation and tax year timeline
  • Eligibility checklist - conditions met and unmet
  • Evidence collection checklist for your case

See which split year case applies and your exact split date.


Residence Tracker

The dashboards answer where you stand today. The tracker keeps answering it all year - log your trips once and it holds a live day count against your personal limit, then tells you before a threshold is crossed rather than after.

  • Live ties-adjusted UK day budget, running across tax years
  • Email alerts before you cross a limit, not after
  • Schengen 90/180 and per-country day counters alongside the UK
  • Evidence log plus an HMRC-ready export - day schedule and full ledger

Log a trip once - your day count and alerts stay current all year.
