This is, by some distance, the question tax professionals hear most: "GST registration ke liye kya kya documents chahiye?" Here is the clean answer — first what everyone needs, then what your business type adds.

The common list (every applicant)

Six things, regardless of business type: PAN of the business or proprietor; Aadhaar of the proprietor, partners or directors; a passport-size photo of each; business address proof — an electricity bill, or a rent agreement along with the owner's NOC, or your own property papers; bank proof — a cancelled cheque or the first page of your statement; and a working mobile number and email, because the portal verifies both by OTP.

GST registration document checklist by business type

What your business type adds

A proprietorship adds nothing — it is the simplest and typically the fastest approved. A partnership or LLP adds the partnership deed or LLP agreement (plus certificate of incorporation for LLPs) and an authorisation letter naming which partner signs. A Pvt Ltd or OPC adds the certificate of incorporation, a board resolution authorising the signatory, and that person's Class 3 digital signature (DSC) — companies must sign with DSC, so getting it made before applying saves a week of waiting at the end.

The three mistakes that cause rejections

Blurry scans are rejection reason number one — scan as clear PDFs or JPGs within the portal's size limits before you begin. Mismatched names come second: the name on PAN, Aadhaar and the deed must align, so fix spelling differences first. Third, address proof in a relative's name without an NOC — the portal wants the chain of permission on paper.

Approval with clean documents commonly takes about a week; every deficiency memo restarts the clock. Preparation is genuinely the whole game.
