GST
India's unified indirect tax on goods and services, replacing multiple state taxes.
By Amit Tyagi, Fitoor Capital · AletheiaAI Glossary
Definition
Goods and Services Tax (GST) is India's primary indirect tax implemented on 1 July 2017. It replaced a fragmented system of central excise, service tax, VAT, and state-level levies. GST is levied at the point of sale and operates on a destination-based consumption model.
GST has five standard rates: 5% (essential goods like food, books), 12% (intermediate goods), 18% (most common for services and goods), 28% (luxury items, automobiles), and 0% (exemptions). Startups must register if annual turnover exceeds ₹40 lakh (₹10 lakh for service providers in specific states). Once registered, businesses collect GST from customers and remit it to the government after claiming input tax credit (ITC) on purchases.
Startups benefit from ITC—paying tax only on value added, not gross revenue. However, GST compliance requires monthly/quarterly filings (GSTR-1, GSTR-3B), accurate invoicing, and record-keeping. Non-compliance attracts penalties up to 10% of tax owed, plus interest at 18% per annum.
For SaaS and digital services, GST is levied where the service recipient is located, not where the service provider operates. This creates complexity for startups serving pan-India or international customers.
India Context
GST registration is mandatory above ₹40 lakh turnover (services: ₹10 lakh in some states). The GSTN (GST Network) portal handles filings—GSTR-1 (outward supplies), GSTR-3B (tax liability), and GSTR-6 (ITC). Monthly filing creates compliance overhead; many early-stage startups hire chartered accountants or use compliance software like Zoho Books or ClearTax, adding ₹5,000–₹15,000 monthly costs.
Inter-state transactions attract Integrated GST (IGST), while intra-state transactions use State GST (SGST) + Central GST (CGST). Startups exporting services are zero-rated, allowing full ITC refund—a significant advantage for B2B SaaS and outsourcing. Reverse charge applies to specified services (consulting, IT services from unregistered vendors), shifting tax payment to the buyer.
Recent changes: e-invoicing is mandatory for turnover above ₹50 crore. GST exemption for startups under government schemes applies only to goods manufacturing, not services, creating inequity for tech startups.
Example
Consider a fintech startup generating ₹50 lakh annual revenue processing payments. Once they cross ₹40 lakh, GST registration becomes mandatory. They charge customers ₹10,000 + 18% GST = ₹11,800. They claim ITC on cloud hosting (₹30,000 + 18% GST), AWS costs, and office rent. Monthly tax liability = GST collected minus ITC. Non-compliance (late GSTR-1 filing) results in ₹1,000–₹10,000 penalty per month.
Another example: a D2C e-commerce brand selling apparel. Stock purchased at ₹100 (12% GST = ₹112 paid). Sold at ₹500 (18% GST = ₹590 to customer). GST payable = ₹90 (₹90 collected minus ₹12 ITC on purchase). Invoicing errors or missing e-way bills trigger GST audits, common for inventory-heavy startups.
