Services
End-to-end GST registration for businesses in Kharar, Mohali, and Chandigarh Tricity — correct HSN/SAC mapping, Aadhaar E-KYC, and GSTIN active within 3–7 working days.
What you get
GST registration is the legal prerequisite for commercial operations in India above the threshold — and the most common cause of delay, rejection, or post-registration notices is a classification or document error that was entirely avoidable. The GSTN portal accepts submissions it cannot fully validate; the jurisdictional officer or automated scrutiny system rejects them later, sometimes months after the GSTIN has been issued and invoices have gone out under the wrong tax rate. We review the application before it is filed, not after it is rejected.

Registration triggers
The turnover threshold is one of four distinct scenarios under which GST registration is required or advantageous. Misreading which applies to your business is the most common cause of delayed registration and retrospective penalty exposure.
Registration is mandatory once aggregate annual turnover crosses ₹40 lakhs for goods or ₹20 lakhs for services. The threshold applies to total turnover under the same PAN across all states — including exempt supplies, nil-rated goods, and exports. Businesses in Special Category States (Himachal Pradesh, Uttarakhand, J&K, and North-Eastern states) have a lower limit of ₹20 lakhs for goods and ₹10 lakhs for services.
Amazon, Flipkart, Meesho, Myntra, Shopify, and any marketplace where an operator facilitates or collects payment requires registration from your first sale — no turnover exemption. The operator withholds TCS at 1% under Section 52 and remits payment only to verified GSTINs. Without a GSTIN, the platform holds your settlements. The Composition Scheme is not available to e-commerce sellers; regular scheme filing is mandatory from the first tax period.
Supplying goods or services across state lines — Mohali to Chandigarh, Punjab to Delhi, or anywhere outside your registered state — triggers mandatory registration before the first inter-state invoice is raised. No turnover threshold applies. This catches growing businesses and pan-India service providers who assume the ₹20/₹40 lakh rule is always relevant: it is not, for inter-state transactions of any size.
Below-threshold businesses that supply to GST-registered companies gain a structural advantage from voluntary registration: you can issue tax invoices, your buyers can claim Input Tax Credit on your invoices, and you become a viable vendor in corporate and institutional procurement. For businesses with high-value B2B customers, the ITC argument frequently converts an optional compliance cost into a competitive differentiator that unlocks contracts.
The HSN code on your registration determines the tax rate on every invoice you issue. Getting it wrong at registration costs more to fix than the registration itself.
Composition Scheme limits and mandatory registration triggers differ by business category and state classification. The table covers standard registered persons; Input Service Distributors, non-resident taxable persons, and persons liable for TDS deduction under Section 51 follow separate rules regardless of turnover.
| Business category | Mandatory registration | Composition limit | Key constraint |
|---|---|---|---|
| Goods — regular states | ₹40 lakhs annual turnover | ₹1.5 crore | No inter-state supply under Composition |
| Services | ₹20 lakhs annual turnover | ₹50 lakhs | Cannot issue tax invoices under Composition |
| Goods — Special Category States | ₹20 lakhs annual turnover | ₹75 lakhs | Applies to NE states, Himachal, Uttarakhand, J&K |
| E-commerce sellers | No threshold — first sale | Not available | TCS mechanism mandates GSTIN before first listing |
| Inter-state suppliers | No threshold — first invoice | Not available | Applies to both goods and services of any value |
Methodology
PAN, Aadhaar, and business address proofs are reviewed for internal consistency before anything is submitted to the GSTN portal. Eligibility is confirmed — mandatory threshold, applicable state category, and correct business classification. Mismatched documents are resolved at this stage, not after a rejection order.
Every principal business activity is mapped to the correct HSN code (goods) or SAC code (services), cross-referenced against the GST rate schedule. Composition Scheme viability is modeled against your estimated turnover and B2B/B2C ratio — a wrong scheme selection at registration costs more in forfeited ITC than any professional fee.
Form GST REG-01 is filed on the GSTN portal with all attachments formatted to jurisdictional officer standards. Aadhaar E-KYC is completed for all authorised signatories. For eligible businesses, we apply the Rule 14A fast-track route to bypass the standard physical verification queue and secure same-day ARN issuance.
If the jurisdictional officer raises a Form GST REG-03 notice, a written reply is prepared and filed within 48 hours — well inside the 7-day statutory window. Physical premise verification, if triggered, is coordinated and attended by our team. No application is abandoned mid-process.
On GSTIN allotment, your invoicing setup is reviewed for correct GSTIN display, HSN/SAC fields, applicable tax rates, and e-invoice eligibility. The first-period GSTR-1 and GSTR-3B due dates are calendared. Where ongoing compliance is required, transition into the managed filing cycle requires no separate mobilization.
