Coming back to India after spending years abroad is an emotional and financial milestone. But here’s something most NRIs miss. Your tax laws may change sooner than you think, usually within months of your arrival. Many returning NRIs believe they will remain non-residents for tax purposes until they have spent a full financial year in India. That assumption can be expensive. Your residential status for the purpose of taxation is not based on your intention but on the days you are in India and the rules have undergone a sea change under the Income-tax Act, 2025. Knowing these rules before you land can help you avoid unexpected tax bills, penalties and compliance headaches.
