Goods and Services Tax registration is mandatory once a business crosses the turnover threshold — in Karnataka, ₹40 lakh for suppliers of goods and ₹20 lakh for services (lower limits apply to certain categories) — and compulsory regardless of turnover for inter-state suppliers, e-commerce sellers, businesses liable under reverse charge and several other categories. Many businesses register voluntarily below the threshold to claim input tax credit or to work with customers who require a GSTIN.
Who this is for
- New businesses, startups and proprietors crossing or approaching the threshold
- Businesses opening a Bengaluru branch (additional place of business or new state registration)
- Traders considering the composition scheme
- Businesses whose registration was cancelled or rejected and needs revival or re-application
- Firms changing constitution, partners, address or business activity (amendments)
When you need it — common situations
Turnover crosses the threshold
Registration must be applied for within the prescribed period; late registration can attract penalty and loss of credit.
A customer or marketplace demands a GSTIN
Voluntary registration, with the compliance calendar that comes with it.
Inter-state supply or e-commerce
Compulsory registration regardless of turnover.
Constitution or address change
Core-field amendments need approval; non-core changes are simpler. Getting the category right avoids a rejected amendment.
What Marvel does
- Determine whether registration is required, which type (regular, composition, casual, non-resident, ISD) and in which state(s)
- Prepare the application on the GST portal with the correct business details, HSN/SAC codes and place-of-business proof
- Assemble the document set in the format the portal and the officer accept — the most common cause of queries is address proof
- Respond to clarification notices within the deadline and follow up to issue of the GSTIN
- Set up the post-registration essentials: invoice format, e-invoicing/e-way bill applicability, return calendar
- Amendments, additional places of business, composition opt-in/opt-out, and cancellation or revocation
Documents and information usually required
- PAN of the business and of proprietor/partners/directors; Aadhaar for authentication
- Constitution documents: partnership deed, certificate of incorporation, MOA/AOA as applicable
- Principal place of business proof: rent agreement plus owner's NOC and utility bill, or property tax receipt/ownership document
- Bank account proof (cancelled cheque or statement)
- Photographs of proprietor/partners/directors; authorised signatory letter or board resolution
- Digital signature (for companies and LLPs)
Step-by-step process
Applicability check
Threshold, category and state analysis; composition eligibility if relevant.
Application
Part A (PAN, mobile, email verification) and Part B (business details, documents) on the GST portal; Aadhaar authentication.
Scrutiny
The officer may raise a clarification (typically with a short deadline) or schedule physical verification of the premises; we respond and prepare you.
GSTIN issued
Registration certificate downloaded; invoicing and returns set up from the effective date.
Timeline and fees
Where Aadhaar authentication succeeds and no query is raised, GSTINs are commonly issued within about a week; queries or physical verification extend this. There is no government fee for registration itself. Our fee is fixed per registration type.

Common problems we see
- Address proof not matching the portal's requirements (missing NOC, expired agreement, utility bill in another name)
- Wrong business category or HSN codes, later requiring amendment
- Aadhaar authentication failures leading to physical verification
- Applications abandoned after a clarification notice, then re-filed with the same defect
- Composition opted where inter-state sales or ineligible supplies make it unavailable

Frequently asked questions
What is the GST registration threshold in Karnataka?
₹40 lakh aggregate annual turnover for suppliers of goods and ₹20 lakh for suppliers of services, with compulsory registration irrespective of turnover for inter-state suppliers, e-commerce sellers, persons liable under reverse charge, non-resident and casual taxable persons and certain others. Thresholds and categories are set by law and change; we confirm your position before applying.
How long does GST registration take?
Commonly within about a week when Aadhaar authentication succeeds and no clarification is raised; longer if the officer seeks documents or physical verification. We track the ARN and respond to notices within the deadline.
Should I choose the composition scheme?
Composition suits small businesses with mainly local B2C sales that do not need to pass on input credit: lower tax rate on turnover, quarterly compliance, but no ITC and no inter-state sales. If your customers are businesses that want credit, or you sell across states, regular registration is usually right. We run the comparison for your numbers.
Can a cancelled GST registration be revived?
A revocation application can be filed within the prescribed period after a suo-motu cancellation, typically after filing pending returns and paying dues. Beyond that period, a fresh registration is usually required. Act quickly — the window is short.
Do I need to visit your office to start?
No. Most matters start with a call or WhatsApp and photographs of your documents. We meet at our Yeshwanthpur office or at the property when a physical inspection, signature or original document is needed.
How are your fees structured?
A fixed professional fee agreed before work starts, quoted after a free first assessment of your documents. Government fees, stamp duty and statutory charges are separate and paid to the authority. We do not quote a headline price for complex matters because the work depends on what the records show.
