Days, my counter of trips abroad, now counts Indian tax residence. It is for NRIs who visit India and want to know how many more days they can spend there this year. It is at allkeep.org/en/days#india-tax, in six languages, and needs no account.
How many days, and how many are left
Add each visit to India to the list, with the day you arrived and the day you left. Days counts your days in the tax year, 1 April to 31 March, planned trips included. It then says how many more days you can spend in India before 31 March and stay non-resident. The rule is section 6 of the Income-tax Act, 2025, which applies from the 2026-27 tax year, and the slip quotes it.
The day you arrive
The Act does not say how a day of travel counts. Tax officers have counted both the day of arrival and the day of departure. The tribunals at Bangalore, Ahmedabad and Delhi (Delhi on 30 December 2025) left the day of arrival out. Days gives its verdict on the stricter count and shows the other count with its own answer, so you can see when the two differ.
The years before
The test depends on your case. A citizen or person of Indian origin visiting from abroad becomes resident only at 182 days. If their Indian income is over ₹15 lakh, 120 days plus 365 in the four years before also make them resident. Days adds up those four years from the same list, and the seven years before as well, which decide RNOR. Pick your case and tick the income box under "Change dates, read the rule".
Days does not decide deemed residence or a ship's crew's voyage days, and the slip says so.
