Documents Required for GST Registration

Documents Required for GST Registration

If you are planning to take GST registration, the first question is always the same – what papers do I need to keep ready? The good news is that for most businesses the core list is short and simple. The part that actually changes from person to person is your address proof (depends on whether you own or rent your place) and your proof of business (depends on whether you are a proprietor, a partnership, a company, an LLP or a HUF).

This page gives you the full checklist, then breaks it down by business type and by the kind of premises you have. One thing that surprises a lot of people in 2026 – you do not need to submit your bank details to get your GST number anymore. The bank proof is handled after your GSTIN is granted. We have explained that clearly further down, because missing it is the single most common reason a new registration gets suspended.

For the complete picture of the service, eligibility, fees and the step-by-step process, see our main GST Registration page.

The Basic Documents Everyone Needs

No matter what type of business you run, the following documents form the base of every GST application. Keep clear, readable scans ready before you start – blurred uploads are a common cause of rejection.

Quick tip: The photograph size limit of 100 KB catches many applicants. If your photo is larger, compress it before uploading, otherwise the portal will not accept it.

Documents by Type of Business

The base documents above stay the same for everyone. What changes is the proof of business constitution – the paper that proves your business legally exists. Here is exactly what each type of business needs.

Proprietorship

This is the simplest case and also the most common. A proprietorship needs the PAN and Aadhaar of the proprietor, a passport-size photo, address proof of the business place, and bank proof (added later). There is no separate incorporation document, because in a proprietorship the proprietor's PAN is the business PAN. Many first-time applicants look for a separate business registration certificate here – you do not need one. Your own PAN and Aadhaar are enough to prove the business.

Partnership Firm

A partnership firm needs the partnership deed, the PAN of the firm, and the PAN and Aadhaar of all partners along with their photographs. You will also need an authorisation letter naming which partner will act as the authorised signatory for GST.

Private Limited Company

A company has the longest list because it is a separate legal entity. You will need the Certificate of Incorporation, the company PAN, the MOA and AOA, and a board resolution authorising the GST registration. Add the PAN, Aadhaar and photograph of all directors, plus the Digital Signature (DSC) of the authorised signatory, which is compulsory for companies. For the full company-specific list, see our Private Limited Company registration documents page.

Limited Liability Partnership (LLP)

An LLP needs the LLP agreement, the Certificate of Incorporation, the PAN of the LLP, and the PAN and Aadhaar of the designated partners. Like companies, an LLP also requires a Digital Signature (DSC) of the authorised signatory.

Hindu Undivided Family (HUF)

A HUF needs the PAN of the HUF and the PAN, Aadhaar and photograph of the Karta (the head of the family who manages the HUF). Address and bank proof follow the same rules as everyone else.

Address Proof – What Counts, Owned vs Rented

Your proof of place of business depends entirely on your relationship to the premises. This is where most confusion happens, so here is the exact document you need for each situation. All of these are accepted directly by the GST portal.

Note: A rent or lease agreement can be uploaded up to 2 MB. All other address documents should be within 100 KB. Make sure the name and address on your proof are clearly readable.

Aadhaar and Biometric Verification – What Changed

This is the part most old articles miss, and it directly affects how your documents are used. Since 10 July 2024, biometric Aadhaar authentication applies across all of India (Notification No. 13/2024 – Central Tax), not just a few pilot states as before.

After you submit your application, one of two things happens. If you choose Aadhaar OTP authentication and the system does not flag your application, the whole process stays online. But if the portal flags you based on its risk checks, you will get an email asking you to visit a GST Suvidha Kendra (GSK) in person for fingerprint and photo verification, along with a check of your original documents.

So in practice, your documents are step one, and verification is step two. Two things that help – keep your original documents ready to carry to the GSK in case you are called, and make sure the name and date of birth on your Aadhaar match your PAN. A mismatch between the two is a common reason authentication fails.

Bank Account Proof – The 30-Day Rule Most People Miss

Here is something that trips up a lot of new registrations. You do not need bank details to get your GSTIN – that field is optional when you apply. But once your GST number is granted, the rule kicks in.

Under Rule 10A of the CGST Rules, you must add your bank proof – a cancelled cheque, passbook copy, or bank statement – within 30 days of getting your registration, or before you file your first GSTR-1 or use the Invoice Furnishing Facility, whichever comes first. The GST portal now automatically suspends registrations that miss this deadline. A suspended GSTIN cannot raise invoices or file returns, so your business effectively stops.

Adding the bank detail is simple – go to Services, then Registration, then Amendment of Registration (Non-Core Fields), then Bank Account, and upload your proof. Do it as soon as your account is ready so you never hit the suspension. This rule does not apply to TDS, TCS or suo-moto registrations.

The 3-Day Fast-Track Route (Rule 14A)

If you are a small business, there is now a faster option. Since 1 November 2025 (Notification No. 18/2025 – Central Tax), small suppliers whose monthly output tax on supplies to registered businesses stays within ₹2.5 lakh can opt for a simplified route that grants the GST number electronically within 3 working days.

The document checklist is the same as a normal application. The difference is that you must select "Yes" under the Rule 14A option when you apply, and complete Aadhaar authentication. A few honest points to keep in mind – this route is optional, you can take only one registration per state under this rule against the same PAN, and if your tax liability later crosses the limit you have to withdraw from the scheme using Form REG-32. For most small proprietors and B2B service providers, it is a genuinely quicker way in.

Common Reasons GST Applications Get Rejected

Most rejections are not about missing documents – they are about small avoidable mistakes. Watch out for these:

• Photograph over 100 KB or in the wrong format
• Blurred or unreadable scans of any document
• Name on the address proof not matching the applicant
• Rent agreement submitted without the landlord's ownership proof
• Name or date of birth on Aadhaar not matching the PAN
• Forgetting the 30-day bank detail step, which leads to suspension after approval
