The long-awaited goods and services tax (GST) is a reality now, which subsumes most of the indirect taxes in it. While tax base will increase the complication of compliance is set to decline. Now the tax is not on manufacturing, sale or provision of service but is on supply. The system of GST is such, where the credit of the GST paid on Inward Supply can be set off towards the GST on outward supply where the chain of tax credit needs to remain intact. Under the new tax regime, all persons involved in the supply of goods or services are required to have registration of GST. Those who are not registered under GST shall not be allowed to collect GST from customers or claim input tax credit (ITC) on inward supply. GST Council has prescribed 20 Lakhs of turnover to be the threshold limit for registration under GST. However, for northeastern states, it is 10 Lakhs. The registration must be applied within 30 days of reaching the threshold limit. For GST, the term Aggregate Turnover means all supplies made by the taxable person whether on his own or behalf of a principal. However, if of registered job worker, the turnover of supplies under job work won’t be included in his turnover.
