After reading your query, I read with interest the provisions concerning OCIs. My views are validated even after reading the provisions concerning OCIs. Now, I summarise my views concerning your situation:
1. Whether you are a citizen of India or not, you are a Resident for the purpose of Indian taxation for the financial year 2022-23. The income earned by you in India will be taxable at the rates applicable to you.
2 As you received income from consultation, the provisions concerning presumptive taxation u/s 44ADA or 44AD of the Income Tax Act, depending upon the nature of your consultancy service, will apply. Most likely you'll be covered u/s 44ADA applicable to professional income. Accordingly, 50% of your gross receipts from the profession will be taken as your income. Accordingly, as your professional income is say Rs 10 Lakhs, the income assessable under the head " Income from business or profession" will be Rs. 5 Lakhs.
3 Most likely, you may not have tax liability, as your taxable income is probably less than Rs 5 Lakhs, after considering the rebate available u/s 87A of the Income Tax Act. Hence, you may get back your TDS as refund after filing your return latest by July 2023 with interest.
4 As you are only an overseas citizen of India, the income earned by you in India may need to be declared in the country of your citizenship and pay taxes there if applicable.
5 As an OCI, the special provisions applicable to you are only about your country of citizenship. But as a resident, you need to disclose about your incomes and assets held abroad.
