Special situations, what to prepare

Home-based businesses

You can use your residence as the principal place of business. Provide a recent electricity bill or property tax receipt, ownership proof, and if not in your name, an NOC from the owner along with their ownership document.

Co-working spaces

Have three items ready, provider NOC, provider’s utility or ownership proof, and your service agreement or monthly invoice. Some officers ask for cabin or desk details, keep a brief description and a photo ready, just in case.

Multiple locations

Declare principal and additional places of business in the application. Each location must have its own proof per owned, rented, or shared rules. You can add more addresses later via amendment.

E-commerce sellers

Registration is usually mandatory regardless of turnover when selling on marketplaces. Standard documents suffice, the crucial part is principal place of business documentation, often your home office or warehouse.

Composition scheme

No extra documents are needed at registration. Ensure you meet turnover and activity conditions, remember that inter-state supplies and input tax credit claims are not allowed under composition.

Aadhaar authentication, the fast track

Why it matters

Successful Aadhaar e-KYC often cuts processing to about 7 working days, reduces the odds of physical verification, and lowers the chance of REG-03 queries.

What to ensure

• Authorized signatory and key persons should have Aadhaar with active mobile numbers.
• Names on PAN and Aadhaar should align, significant differences may need an affidavit.

If it fails

Expect physical or video checks and longer timelines. Fix mismatches on Aadhaar if needed and reattempt e-KYC.

File formats and upload tips

• Use color scans when possible, ensure text is crisp and fully readable.
• PDF for multi-page documents, JPEG for photos or single pages, keep within portal size limits.
• Use clear names like PAN_ABC_LLP.pdf, RentAgreement_MainOffice.pdf to avoid mix-ups.
• Utility bills from the last 2 to 3 months work best, cancelled cheques must have pre-printed names.

GST registration process, what happens step by step

Understanding the flow reduces anxiety and errors. For an expanded walkthrough, explore GST registration in India.

Generate your TRN

Start on the GST portal, choose Services, Registration, New Registration, then verify OTPs to get your TRN. Save it for later sessions.

Complete the application

Log in with TRN, fill Part B of REG-01, add addresses, promoters, and bank details, upload all documents in the asked format, and recheck every field.

Authentication and submission

Finish Aadhaar e-KYC for signatories, apply DSC for companies and LLPs, or use EVC or OTP for others, then submit to generate your ARN.

Track and respond

Monitor status daily and watch for REG-03. If a notice arrives, respond within 7 days with clear, complete documents. Missing the deadline means starting over.

Approval and go-live

Download REG-06 once approved, update your invoices and displays with the GSTIN immediately, and issue GST-compliant invoices from the effective date.

Common rejection reasons, and how to avoid them

• Name or address mismatches: Keep PAN, bank proof, and premises proof perfectly aligned. If variations are unavoidable, attach an affidavit or name change evidence.
• Incomplete address proof: For rented or shared offices, always submit the complete set, agreement, recent utility bill, and NOC.
• Poor scans or outdated papers: Re-scan, use recent utility bills and bank statements, upload all pages of deeds and agreements.
• Missing authorization: If the signatory is not the proprietor or Karta, include a proper resolution or authorization letter that explicitly mentions GST matters.
• Skipping Aadhaar e-KYC: Expect delays and extra checks if you skip it, finish e-KYC to accelerate approval.
• Ignoring REG-03: Notices have tight timelines, respond fast and fully.

FAQ

What exact documents do I need for GST registration as a first-time founder?

Start with entity PAN, Aadhaar for the authorized signatory, photographs, principal place of business proof based on owned, rented, or shared rules, bank proof, and authorization letters or resolutions where applicable. Companies and LLPs also need a Class 3 DSC. If you want a tailored list and a pre-check to avoid REG-03, Virtual Accounting by AI Accountant can prepare and validate your pack end to end.

Can I use my home as my principal place of business without issues?

Yes, provide a recent electricity or property tax bill, ownership proof, and an NOC if the property is not in your name. Many startups begin from home and clear on the first attempt when the address documents match the portal entry exactly.

Do I need bank details at the time of applying, or can I add them later?

You can add bank details within 30 days of registration or before your first return, but adding them upfront reduces notices and speeds activation. A cancelled cheque with pre-printed name, the first page of the passbook, or a recent statement works.

Is a DSC compulsory for proprietors or partnerships?

No, DSC is mandatory for companies and LLPs only. Proprietors, partnerships, HUFs, trusts, and societies can use Aadhaar OTP or EVC. If you expect frequent filings and authorizations, a DSC can still be convenient.

How recent should my utility bill be for address proof?

Within the last 2 to 3 months. Older bills often trigger REG-03 requests for newer proof of possession. Always combine the bill with the right agreement and NOC when the premises are rented or shared.

What if my rent agreement is not registered, will my application get rejected?

Unregistered agreements are usually accepted if paired with the latest utility bill of the premises and a clear owner NOC. A registered agreement reduces queries, but is not an absolute requirement in most cases.

Do all partners or directors need Aadhaar for Aadhaar authentication?

At minimum, the authorized signatory must complete Aadhaar e-KYC. Having Aadhaar for all partners or directors helps speed verification, reduces queries, and avoids physical checks.

I sell on marketplaces, are there extra documents for e-commerce GST?

No special documents beyond the standard set. Ensure your principal place of business proof is strong, your GSTIN will be required for marketplace onboarding after approval.

How long does approval take in 2026 if I do everything right?

With successful Aadhaar e-KYC and clear documents, about 7 working days is common. Without Aadhaar authentication, or if you receive a REG-03, expect 15 to 30 days. Submitting complete, legible, and consistent proofs is the fastest path.

I received a REG-03 notice, how should I respond to avoid rejection?

Log in immediately, read the query carefully, and upload the exact documents requested, not substitutes. Respond within 7 days. If you need help interpreting the officer’s note or assembling the right combination, Virtual Accounting by AI Accountant can draft and upload the response for you.

Can a foreign company get GST registration without Indian Aadhaar?

Yes, non-resident taxable persons use passports and home country incorporation or tax documents, and must appoint an Indian authorized signatory with PAN and Aadhaar to complete e-KYC. You will also need a temporary Indian address proof and advance tax deposit challans.

Is there any government fee for GST registration on the official portal?

No, government registration on the official portal is free. Professional fees apply only if you engage service providers to help prepare and file your application.

What is the most common reason startups get rejected on the first attempt?

Address proof gaps, especially for rented or shared spaces, are the top reason. Officers look for the specific trio, agreement, recent utility bill, and owner or provider NOC. Submitting only a rent agreement is not enough. A pre-submission review by Virtual Accounting by AI Accountant eliminates these gaps.

Do I need to upload bank proof if my current account is not yet opened?

You can submit the application and add bank details within 30 days, but it is best to open the account and upload proof before filing your first return. This avoids additional notices and speeds operational onboarding with customers and marketplaces.

What if my PAN and Aadhaar names do not match exactly?

Minor variations often pass, but significant differences may cause Aadhaar e-KYC failures and delays. Update Aadhaar or prepare an affidavit and supporting evidence for name changes. Getting this right upfront saves weeks.
