Calculators
Count your days, in your browser.
These calculators run the same rules engine as the app, validated against the same golden test fixtures. They run entirely client-side: nothing you enter is transmitted, stored or seen by us.
US
Physical presence test calculator (FEIE)
Check the FEIE physical presence test: full days abroad, the best 12-month window, how many days you are short, and the earliest date you could qualify.
IN
Residential status calculator (India)
Work out your Indian residential status: Resident, RNOR or Non-resident, with the limb that decided it and how far you are from the next threshold.
SCHENGEN
Schengen 90/180 calculator
Check your Schengen short-stay allowance: days used, days remaining, the date you would breach the limit, and the next day a day frees up.
UK
Statutory Residence Test calculator (UK SRT)
Work through the UK Statutory Residence Test in order: automatic overseas tests, automatic UK tests, then sufficient ties, with the deeming rule applied.
US
Substantial Presence Test calculator
Work out whether you meet the IRS Substantial Presence Test: the three-year weighted count, days remaining, and your latest safe departure date.
