GST Registration your GSTIN, filed right the first time.
End-to-end GST registration services in Mumbai and across India — new GSTIN application, regular and composition scheme enrolment, voluntary GST registration, multi-state GST numbers, and Aadhaar-authenticated filing for proprietors, partnerships, LLPs, and private limited companies.
GST registration is the foundational compliance for every business operating in India under the Goods and Services Tax regime. Once aggregate turnover crosses the threshold limit of Rs 40 lakh for goods (Rs 20 lakh in special category states) or Rs 20 lakh for services (Rs 10 lakh in special category states), GSTIN registration becomes mandatory. Inter-state suppliers, e-commerce operators, casual taxable persons, non-resident taxable persons, and persons liable to deduct or collect tax at source must obtain GST registration irrespective of turnover.
Beyond the legal mandate, voluntary GST registration under Section 25(3) of the CGST Act is increasingly common among startups, freelancers, and small service providers. The 15-digit GSTIN unlocks input tax credit, allows you to issue tax invoices, makes you eligible to deal with B2B and GST-registered buyers, supports onboarding to e-commerce marketplaces, and signals statutory credibility to lenders, investors, and government tenders.
Our GST registration practice covers the entire lifecycle — eligibility assessment, document preparation, Form GST REG-01 filing, Aadhaar authentication, response to deficiency memos in Form GST REG-03, physical verification coordination, GSTIN allotment, and post-registration setup including invoice format, HSN/SAC code mapping, and GST return filing scheduling. Whether you are a proprietorship, partnership firm, LLP, private limited company, trust, or society, our Chartered Accountants ensure your GST number application is filed accurately and processed without back-and-forth.
