How to Reply to a GST Registration Notice (REG-03)
If you applied for GST registration and got a notice in Form GST REG-03, don’t panic. This notice doesn’t mean your application is rejected. It simply means the GST officer wants some extra information or a clarification before approving your registration. Here’s everything you need to know about replying to it correctly and on time.

What Is a GST REG-03 Notice?
When you submit a GST registration application, the officer checks the details and documents you’ve uploaded. If something looks incomplete, unclear, or mismatched, the officer doesn’t reject the application right away. Instead, they issue a notice in Form GST REG-03, asking you to explain or submit more proof.
This notice is issued under Rule 9 of the CGST Rules, 2017. These notices are issued when discrepancies, inconsistencies, or missing information are identified in a GST application. Common reasons include:
- Address proof that doesn’t match the application
- Unclear business activity details
- Missing or blurry document uploads
- Mismatch between PAN details and the application
- Signature or authorisation issues
Think of REG-03 as the officer saying “I need a bit more before I can approve this,” not “I’m rejecting this.”
Which Form Do You Use to Reply?
You don’t reply to REG-03 directly with a letter. The applicant must submit a reply electronically through Form GST REG-04 within the prescribed timeline, usually 7 working days. This form is filed entirely on the GST portal, and there’s no offline option.
How Much Time Do You Have to Reply?
You must file your reply in Form GST REG-04 within seven working days from the date the REG-03 notice was served. This deadline is strict. The portal doesn’t give grace periods, and once the window closes, you generally can’t submit a late reply through the same application.
A quick tip: Note down the exact date your notice was issued, not the date you happened to check your portal. The clock starts from issuance, so checking your notices and orders section daily during this period is worth the effort.

What Happens If You Miss the Deadline?
This is where people get into real trouble. If you don’t reply to REG-03 within 7 working days, the officer will issue a rejection order in Form GST REG-05, without any further chance to clarify. After a REG-05 rejection, your only options are to appeal before the Appellate Authority within the prescribed period, or start your registration application all over again. Both routes cost you time, so it’s far easier to just reply on time the first go.
Step-by-Step: How to Reply to GST REG-03 on the Portal
Here’s the process laid out simply, so you can follow it without getting lost in the portal’s menus.
Step 1: Log in to the GST portal
Use your TRN (Temporary Reference Number) if you’re still in the middle of a fresh registration, or your regular login credentials if you already have other access.
Step 2: Go to the clarification section
Navigate to Services → Registration → Application for Filing Clarifications. On some portal versions, this also shows up under Services → User Services → View Notices and Orders.
For general guidance on locating notices through an existing GST login, read our guide to checking GST notices online. Fresh registration applicants should follow the clarification route available against their TRN or ARN.
Step 3: Pull up your notice using the ARN
Enter your Application Reference Number (ARN) to locate the pending application and open the REG-03 notice attached to it.
Step 4: Read the notice carefully, line by line
Before typing anything, note the notice reference number, the date of issue, and exactly what the officer is asking for. A lot of rejected replies happen simply because the applicant answered the wrong question.
Step 5: Draft your response in the reply box
Click “Reply” against the REG-03 notice. This opens the REG-04 form, where you’ll find a text box for your written response.
Step 6: Attach your supporting documents
Upload whatever proves your point. Address proof, rent agreements, utility bills, corrected PAN copies, or board resolutions, depending on what the officer flagged.
Step 7: Choose your authorised signatory and submit
Select the name and place of the authorised signatory from the dropdown, then verify and submit using DSC or EVC.
Once submitted, the officer reviews your reply and either approves the registration or, in rare cases, calls you for a personal hearing if the clarification still leaves doubts.
After submitting REG-04, use our GST ARN status guide to understand how to track the application and interpret clarification-related status updates.
Sample Reply Format for GST REG-03
You don’t need fancy legal language for this. A clear, factual, point-by-point response works best. Here’s a simple format you can follow:
Subject: Reply to Notice in Form GST REG-03
Reference No.: [Notice Number]
Date of Notice: [Date]
ARN: [Application Reference Number]
Applicant Name: [Legal Name]
Trade Name: [Trade Name, if any]
Respected Sir/Madam,
With reference to the above notice, we submit our point-wise reply as follows:
Query 1: [Restate the exact query mentioned in the notice]
Reply: [Give a clear, factual explanation, and mention the supporting document attached]
Query 2: [Restate the second query, if any]
Reply: [Your explanation with reference to the attached proof]
We trust this clarifies the matter and request you to kindly proceed with the approval of our GST registration application.
Thanking you,
[Authorised Signatory Name]
[Designation]
[Date]
Keep each answer short and to the point. Officers go through dozens of these replies a day, and a long, vague explanation usually gets more scrutiny than a short, specific one.

Documents You May Need to Attach
The exact documents depend on what the officer has flagged, but these are commonly requested:
- Address proof (electricity bill, property tax receipt, rent or lease agreement)
- No Objection Certificate (NOC) from the property owner, if applicable
- Clear, legible copies of PAN and Aadhaar
- Bank account proof, such as a cancelled cheque or bank statement
- Board resolution or authorisation letter, for companies and LLPs
- Photographs of the business premises, if address verification is the issue
Always upload fresh, clear copies rather than reusing the same blurry scan that triggered the notice in the first place.
For a broader reference, review the GST registration document requirements, then attach the documents relevant to the specific queries in your notice.
Common Mistakes to Avoid
Final Thoughts
A GST REG-03 notice is routine, not a red flag. The department simply wants one more piece of information before approving your registration. Reply within seven working days, answer each query directly, attach solid proof, and you’ll likely see your registration approved without further back-and-forth. If the query is genuinely confusing or your documents don’t fully resolve it, it’s worth getting a tax professional to review your draft reply before you hit submit.
