GST Registration in Chennai
GST (Goods and Services Tax) is a single tax system that applies to the supply of goods and services across India. Businesses that exceed a certain annual turnover threshold are required to register for GST. In Chennai, GST registration allows companies to collect GST from customers and remit it to the government, ensuring legal compliance. It also offers the benefit of claiming Input Tax Credit (ITC), which allows the business to offset the GST paid on their inputs. This reduces the overall tax liability for businesses. Moreover, registering for GST adds to the business's legitimacy, helping to establish trust with customers, vendors, and financial institutions.
