If you fall in the category of 'resident' and ordinary resident of India your global income will be taxable in India. This income may have been earned or received outside India, but it shall be taxed in India. Although your income earned outside India will be taxable in India, but you will get the benefit of DTAA (Double Tax Avoidance Agreement), if any, between India & the country where you earn income. Only the marginal tax, if liable, will be payable by you being the rate of tax higher in India.
