How TaxDin counts your days
In short
TaxDin records one fact per day per person — the country you were in at that midnight — and derives everything else from it. Days are re-bucketed per country (UK tax year, Indian financial year, calendar year), untracked days are surfaced rather than guessed, and manual corrections always beat bulk imports.
Midnight-based counting
Most residency rules — including the UK SRT — turn on where you were at midnight, not which countries you touched during the day. TaxDin therefore stores a single location per person per date, which keeps the record unambiguous and auditable.
Honest gaps, protected edits
Days you haven't logged are shown as 'untracked', never silently zero-filled — a partial history produces partial answers, clearly labelled.
When you correct a day by hand, that day is protected: spreadsheet re-imports can never overwrite a manual edit.
Per-country year boundaries
- United Kingdom: 6 April – 5 April tax year, midnights
- India: 1 April – 31 March financial year, days of presence
- Singapore: calendar year, days of presence

Frequently asked questions
What happens on a travel day touching two countries?
You record the country where you were at midnight — the measure most residency tests actually use. If a specific rule treats presence differently, your midnight record is still the cleanest starting point.
Can TaxDin's automated readouts be wrong?
They are only as good as your data and are a day-counting aid, not tax advice. Borderline positions — split years, treaty ties, exceptional circumstances — should always go to a qualified adviser with your TaxDin export in hand.
