If you run a services firm in India, GST registration and input tax credit are two halves of the same decision. Registration is what puts you inside the GST system. Input tax credit (ITC) is the mechanism that makes being inside it worthwhile, because it lets you recover the GST you pay on rent, laptops, software, and subcontractors against the GST you collect from clients.<\/span><\/p>\n

Most guides treat these as separate topics. In practice, they are one workflow: you register, you set up your vendors and invoices correctly, your suppliers file on time, you match what they filed against what you bought, and you claim the credit. Break any link in that chain and the credit stalls in your ledger or disappears entirely.<\/span><\/p>\n

This guide walks through the whole chain. It covers when registration becomes mandatory, how the process works after the November 2025 changes, the exact conditions for claiming ITC under Section 16 of the CGST Act, what is blocked under Section 17(5), how GSTR-2B and the Invoice Management System (IMS) now shape your monthly claim, and a worked example for a 40-person consulting firm. It ends with a practical monthly routine you can hand to your finance team.<\/span><\/p>\n

One note on scope: this is an operational guide, written for founders and finance leads at project-driven services firms. It is accurate as of September 2026 and links to the statute wherever a rule is stated. It is not tax advice. Confirm your specific position with a chartered accountant.<\/span><\/p>\n

What GST Registration And Input Tax Credit Mean Together<\/b><\/h2>\n

GST registration is the process of obtaining a 15-digit GSTIN from the GST portal, so your business can collect GST on its sales, file returns, and claim ITC. Input tax credit is the credit for GST already paid on business purchases, which a registered person can set off against the GST payable on their own supplies.<\/span><\/p>\n

The connection is written directly into the law. Under<\/span> Section 16(1) of the CGST Act<\/span><\/a>, only a “registered person” is entitled to take credit of input tax on goods or services used in the course or furtherance of business. Without registration, there is no credit to claim. An unregistered consultancy paying 18% GST on its office lease simply absorbs that tax as a cost.<\/span><\/p>\n

For a services firm, this matters more than it might for a trader, because your inputs are mostly taxed at 18% and your clients are mostly registered businesses who expect a GST invoice. Registration lets you pass GST through cleanly and recover what you spend on the way.<\/span><\/p>\n

When GST Registration Becomes Mandatory<\/b><\/h2>\n

Registration is triggered by aggregate turnover, and the thresholds depend on what you supply and where you operate.<\/span><\/p>\n\n\n\n\n\n
Type of supply<\/b><\/td>\nStandard states<\/b><\/td>\nSpecial category states<\/b><\/td>\n<\/tr>\n
Exclusively goods<\/span><\/td>\nRs 40 lakh<\/span><\/td>\nRs 20 lakh<\/span><\/td>\n<\/tr>\n
Services, or goods plus services<\/span><\/td>\nRs 20 lakh<\/span><\/td>\nRs 10 lakh<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The base rule sits in<\/span> Section 22 of the CGST Act<\/span><\/a>, which sets the Rs 20 lakh threshold (Rs 10 lakh for special category states) for any supplier of goods or services. The higher Rs 40 lakh limit for exclusive goods suppliers came through Notification 10\/2019 Central Tax, effective 1 April 2019. Some states opted differently, so check your state’s position if you are near the line.<\/span><\/p>\n
