RNOR (Resident but Not Ordinarily Resident) status can exempt your foreign income from Indian tax for up to 3 years. The date you move changes everything — this tool shows you exactly how.
Withdrawing 401(k) funds during your RNOR window (the first 2-3 years after return) avoids Indian tax on that income entirely, since foreign-sourced withdrawals aren't taxed during RNOR status — though US taxes and a possible 10% early-withdrawal penalty (if under 59½) still apply. This timing can save 30-40% in combined taxes compared to withdrawing after becoming a full ROR.
