Hi,
- Until August 2018, you received salary and TDS was deducted on such salary therefore no need to worry for payment of taxes at the time of filing of ITR in the m/o July 19.
- From sep.2018, you received consultancy charges against which you raised invoices to overseas clients. This income falls into definition of Income from profession. Under Income tax, either you should pay advance tax on estimated basis or pay income tax in the form of self assessment tax alongwith the interest for non-payment of advance tax at the time of filing of ITR. You can file ITR-4 i.e. presumptive tax and should both salary income and income from profession. For professional income, as the income is less than Rs. 50 lacs, you need to pay tax on atleast Rs.5 lacs (i.e. 50% of 10 lacs).
- Under GST, you need to register and obtain LUT. In GST, your services are termed as export of services and to export without payment of taxes, you need to obtain letter of undertaking.
Thanks
