GST registration is not simply “getting a GST number”. Your registration type, state, business constitution, place of business, nature of supplies and future compliance obligations all matter. StartStartup helps you determine whether GST registration is required, voluntary or better avoided for now.

Government GST registration has no filing fee. Our plans cover professional preparation, filing and support. Current online competitors advertise prices ranging from roughly ₹399 to ₹1,500+ for basic registration, while some bundled platforms price considerably higher.
For a straightforward single-state application with standard documentation.
For businesses that want registration plus a practical first-month GST setup.
For founders setting up a more serious B2B / multi-state operation.
Prices are professional assistance fees for the scope described. Government fees, if any become applicable for a separate service, statutory deposits, tax payments, return filing and special-case work are outside these packages unless expressly included.
GST registration depends on aggregate turnover, nature and location of supplies, the type of business and specific compulsory-registration provisions. The ordinary threshold is not the only test. CBIC's registration framework also contains exceptions and special cases.
We first map your actual business model, then decide whether you should register, whether voluntary registration makes commercial sense, and what compliance comes after the GSTIN.
The GST portal does not prescribe a government fee for obtaining registration. Professional platforms charge for preparation, filing, follow-up and support.
See our professional feesThresholds are only one part of the answer. The nature of your supplies and compulsory-registration provisions can change the result.
For eligible suppliers of goods in states where the higher threshold applies, registration exemption can generally extend up to ₹40 lakh aggregate turnover, subject to the applicable conditions and state rules.
The commonly applicable threshold for service suppliers is ₹20 lakh, with lower thresholds applying in specified special-category states. Exceptions can apply.
Certain categories can require registration even below the normal turnover threshold. This is why a turnover-only calculator can give the wrong answer.
These are examples, not an automatic conclusion that registration is mandatory in every case. The exact applicability must be checked against the current law and facts.
A clean application is much easier when the legal name, address, constitution and business activity are settled first.
Proprietorship, partnership, LLP, company or another constitution changes the document set and authorised-signatory requirements.
Ownership/rent/lease documentation and address evidence should match the place from which the business is actually operated.
Products/services, HSN/SAC, nature of supply and expected customers affect the registration profile.
Regular vs composition eligibility, ITC expectations and B2B/B2C mix should be considered before filing.

The GST registration application is made through the common portal using FORM GST REG-01. Depending on the case, authentication and verification steps may be involved before registration is granted.
Confirm state, constitution, business activity, turnover and registration reason.
Prepare REG-01 details, business address proof, constitution documents and authorised-signatory information.
Complete the authentication or verification route applicable to the applicant.
Track the application, respond to any deficiency memo if issued, and obtain the registration certificate.
The exact documents depend on the constitution and premises. A proprietor and a private limited company do not submit the same file.
A GSTIN can create ongoing obligations. Your return frequency, invoice rules, payment, records, e-invoicing/e-way bill applicability and annual compliance depend on your facts and current rules.
GSTR-1, GSTR-3B and other applicable returns.
Correct GST invoices, tax rates and mandatory particulars.
Track eligible input tax credit and reconcile appropriately.
Keep registration details updated when business facts change.
They start with mismatched information, weak address proof or an unclear business model.
PAN, incorporation records, rent documents and application details do not line up.
The principal place of business evidence is incomplete or does not support the claimed premises.
Business activity, HSN/SAC or nature of supply is described too broadly or inaccurately.
A clarification/deficiency notice is received and the response is incomplete, late or inconsistent.
For StartStartup, GST should be part of a founder's broader formalisation journey.
Sometimes a business below the threshold chooses GST registration for commercial reasons — for example, B2B customers may prefer a registered supplier or the business may want to evaluate input-tax-credit implications.
But voluntary registration also brings GST compliance. CBIC's FAQ notes that a person voluntarily registering while below the threshold becomes a taxable person after registration.
Don't register merely because “GST looks professional”. Register when the law requires it or when the commercial case makes sense.
Tell us what you sell, where you operate, your business structure and approximate turnover. We'll help you understand the registration decision before you pay for a filing.
