If you relocated from India to Singapore in December 2022, you'll need to file your Indian income tax return for FY 2022-23. You'll pay tax in India for income earned from April to November 2022. The key question is whether income earned after your move, from December 2022 to March 2023, is also taxable in India, especially since you'll be paying tax in Singapore for this period too. It's recommended to consult a tax professional for definitive guidance on these complex international tax rules.
