Tracks the 120-day threshold for the India NRI tax residency test. For certain Indian citizens or Persons of Indian Origin (PIO) visiting India with qualifying Indian income above ₹15 lakh, spending 120 days or more in India during the tax year may result in Indian tax residency if they also spent 365 days or more in India during the preceding four years. The Indian tax year runs from 1 April to 31 March. This tracker only counts days toward the 120-day threshold and does not evaluate income, citizenship/PIO status, the preceding four-year requirement, or other tax-residency conditions.
