GST Registration Documents for an LLP: Checklist and the DSC Rule
An LLP needs its PAN, the certificate of incorporation, the LLP agreement, PAN, Aadhaar and photographs of the designated partners, an authorisation for the signatory, proof of the place of business and bank proof. One thing sets it apart from an ordinary firm: the application has to be signed with a digital signature certificate (DSC).
- The GST portal manual says digital signing with a DSC is mandatory for LLPs and companies. Aadhaar e-sign and OTP signing are for other kinds of applicants.
- Aadhaar authentication is done for one designated partner and the primary authorised signatory.
- The portal does not make the DIN field compulsory for an LLP. It does for companies.
- Form GST REG-01 does not name a constitution document for LLPs. In practice the certificate of incorporation is uploaded.

What does an LLP need?
An LLP is a body of its own, created by registration with the Ministry of Corporate Affairs. So the papers have to show the LLP itself, the designated partners who run it and the one person who will sign.
| Document | What to keep in mind |
|---|---|
| PAN of the LLP | The portal checks the name and the constitution against the income tax database. Type the name as printed on the PAN, with "LLP" exactly as it appears there. |
| Certificate of incorporation | Issued by the Registrar when the LLP was formed. It carries the LLP's identification number (LLPIN). |
| LLP agreement | Shows who the partners are and who may act for the LLP. Keep it scanned and ready. |
| PAN and Aadhaar of designated partners | Entered in the Promoter / Partners tab, which takes up to 10 people. |
| Photographs of designated partners | JPEG, up to 100 KB each. |
| Authorisation for the signatory | A resolution or letter from the partners naming the authorised signatory. PDF or JPEG, up to 1 MB. |
| Proof of place of business | Electricity bill, property tax receipt or municipal khata copy, plus the rent agreement if rented. Up to 1 MB. |
| Bank proof | Cancelled cheque, passbook first page or bank statement of the LLP's account. Added after the GSTIN, within 30 days or before the first GSTR-1. |
| DSC of the signatory | Not an upload. It is the USB token used to sign the application. |
A word of care on the second and third rows. The document list in Form GST REG-01 names the partnership deed for firms and a registration certificate for trusts and societies. It is silent on LLPs. The certificate of incorporation is what applicants upload in practice, and it is what our own registration form asks for, along with the LLP agreement.
How is an LLP different from a partnership firm here?
Many partners move from a firm to an LLP and assume the GST paperwork is the same. Four things change.
| Point | Partnership firm | LLP |
|---|---|---|
| Proof that it exists | Partnership deed | Certificate of incorporation, with the LLP agreement as support |
| Who is listed | Partners | Designated partners |
| How the form is signed | Aadhaar e-sign, OTP (EVC) or DSC | DSC only |
| Aadhaar authentication | One partner and the primary authorised signatory | One designated partner and the primary authorised signatory |

How do you get the DSC ready?
Why does the portal insist on a DSC for an LLP? Because an LLP acts only through people it has authorised, and a DSC ties the signature to one named person. Do these four things before you open the form.
- Check the token. The DSC must belong to the person you will name as authorised signatory, and it must not have expired.
- Install emSigner. This is the signing utility linked from the GST portal. The manual says it must be running with administrator permissions.
- Register the DSC. A DSC that is not registered on the portal has to be registered first.
- Sign in the Verification tab. Pick the signatory, enter the place, choose to submit with DSC and select the certificate.
Which class of DSC? The instructions to Form GST REG-01 say class 2 and above. Certificates sold today are generally class 3, as far as I can tell from sellers' sites, and that meets the condition. I could not confirm this point on an official page.
Who signs for an LLP?
The form's instructions say a designated partner authenticates an LLP's application. The partners record who that is in a resolution or an authorisation letter, and the portal takes it as proof of appointment of the authorised signatory. The signatory cannot be a minor.
If the signatory is a designated partner, switch on "Also Authorized Signatory" in the Promoter / Partners tab so you do not type the details twice. Then mark that person as the primary authorised signatory. The OTPs for the application go to that person's mobile and email.
A worked example
Tulsi Naturals LLP in Bengaluru sells herbal teas and expects sales of Rs 9,00,000 a month. The designated partners are Nikhil and Farah. Their office is rented at Rs 22,000 a month on a registered lease, so the premises papers are clean.
Farah is named as authorised signatory. On filing day her DSC turns out to have expired two months ago. A new token will take a few days, and the Temporary Reference Number that holds their draft is valid for only 15 days.
They have two choices. Wait for Farah's new DSC, or change the signatory to Nikhil, whose DSC is valid, and redo the authorisation letter in his name. They pick Nikhil and file the same evening. Had they waited a week, the cost would have been about Rs 2,10,000 of sales (Rs 9,00,000 divided by 30, times 7), plus rent running on an office that could not bill.
What is the mistake people usually make?
Treating the DSC as the last step. Every other paper can be scanned in an hour. The DSC is the one thing that needs another agency and a few days. I see three versions of the same slip:
- The DSC expired after incorporation and nobody noticed.
- The only valid DSC belongs to a partner who is not the named signatory, or to the firm's accountant.
- The name on the DSC does not match the signatory's PAN. Secondary guides say the portal matches the two, so fix the name before you buy.
Plug the token in and check its expiry date on the day you decide to register, not on the day you file.
Can the officer ask for more?
CBIC Instruction 03/2025-GST lets an officer raise a notice only on listed grounds, such as an incomplete or unreadable document or an address that does not match its proof. A document outside the list needs the approval of a Deputy or Assistant Commissioner. If a notice comes, you reply in Form GST REG-04 within 7 working days. Our step-by-step guide to the online process shows where each tab sits.
