Startup Advisory provides fast, 100% online GST registration in Delhi NCR – serving businesses in Delhi, Gurugram (Gurgaon), Noida, Greater Noida, Ghaziabad and Faridabad. Our CA-led team in Saket, South Delhi gets you a valid GSTIN and sets you up for smooth, ongoing GST compliance.
GST registration is the gateway to operating a fully compliant business in India. Once you have a GSTIN, you can legally charge GST on your invoices, claim input tax credit on your purchases, sell on e-commerce marketplaces, and trade across state lines. For many businesses it isn't optional – crossing the turnover threshold, or simply selling online or inter-state, makes registration mandatory.
We make the process painless: we prepare your application, guide you through Aadhaar authentication, deal with the GST portal, and hand you a registration certificate – then help you stay compliant with your returns.
You must register for GST if any of the following applies to your business:
Turnover threshold: aggregate turnover above ₹40 lakh (goods) or ₹20 lakh (services) – ₹20 lakh / ₹10 lakh in special category states.
Inter-state supply of goods – mandatory regardless of turnover.
E-commerce sellers and operators (Amazon, Flipkart, your own online store).
Casual and non-resident taxable persons, and anyone liable under reverse charge.
Input Service Distributors and those required to deduct TDS or collect TCS.
Voluntary registration – even below the threshold, to claim input tax credit and boost credibility.
Input Tax Credit: claim credit for GST paid on your purchases and expenses.
Sell online & inter-state: a GSTIN is required to list on marketplaces and supply across states.
Business credibility: a valid GSTIN reassures customers, vendors and banks.
Legal compliance: avoid heavy penalties for operating without required registration.
Access to tenders & B2B clients: most corporate and government buyers deal only with GST-registered vendors.

PAN of the business / proprietor
Aadhaar & photo of proprietor / partners / directors
Constitution proof (partnership deed / COI / registration certificate)
Authorisation letter / board resolution for the signatory
Place of business proof – electricity / water bill or property-tax receipt
Rent agreement + NOC (if premises are rented)
Bank proof – cancelled cheque / statement / passbook
Digital Signature (for companies & LLPs) or mobile/email for EVC
The entire registration is online on the GST portal through Form REG-01. Here's how we do it for you:
Step 1 – Part A of REG-01: We submit your PAN, mobile and email to generate a Temporary Reference Number (TRN).
Step 2 – Part B of REG-01: We complete business details, HSN/SAC codes, promoters, bank details and upload your documents.
Step 3 – Aadhaar authentication: The signatory and a promoter complete Aadhaar OTP authentication (or biometric verification at a GST Suvidha Kendra, if flagged).
Step 4 – ARN & verification: An Application Reference Number (ARN) is generated and the application is processed by the system or officer.
Step 5 – GSTIN & certificate: On approval, your GSTIN is allotted and the GST registration certificate (REG-06) is available to download.
Typical timeline: 3 working days under the simplified scheme / for low-risk applicants, about 7 working days in a normal case, and up to 30 working days where physical verification is required.
The GST portal now offers a faster, more transparent registration experience. Key changes currently in effect:
Small businesses can choose between the regular scheme and the simpler composition scheme:
| Feature | Regular Scheme | Composition Scheme |

| Returns | Monthly / quarterly | Quarterly + annual (simpler) |

A GSTIN comes with regular filing duties. We handle these for you so you never miss a deadline:
GSTR-1 – details of outward supplies (monthly or quarterly under QRMP).
GSTR-3B – summary return and tax payment (monthly or quarterly).
GSTR-9 – annual return (for turnover above the prescribed limit).
E-invoicing & e-way bills – where applicable based on turnover and goods movement.
Let us handle your filings end-to-end with our bookkeeping and tax advisory services.
