Whether you are starting a new business or expanding an existing one, understanding the Goods and Services Tax (GST) timeline is crucial for smooth financial operations and complete compliance. GST has streamlined India’s indirect tax structure, but it also comes with fixed procedures and deadlines that business owners must follow diligently. Missing these deadlines can lead to penalties, interest payments, and even disruption in input tax credit claims — all of which may impact the financial health of your company.
Many entrepreneurs feel overwhelmed by the multiple steps involved in GST registration, returns filing, reconciliation, and annual compliance. The process becomes even more complex when your business grows, transactions increase, or new regulatory updates come into effect. That is why having a clear, step-by-step timeline by gst consultancy services helps you prepare documents, adhere to statutory dates, and avoid last-minute stress. This guide breaks down the entire journey from GST registration to monthly and annual filing deadlines, offering a structured view that every business must follow.
GST Registration to Filing: A Complete Step-by-Step Timeline
Pre-Registration Preparation (Days 1–3)
Before applying for GST registration, businesses must gather the required documents. These generally include:
- PAN card of the business or applicant
- Identity and address proof of promoters
- Address proof for the principal place of business
- Bank account details
- Photographs of authorised signatories
Ensuring that all documents are in the correct format and updated speeds up the approval process.
GST Registration Application (Days 3–7)
Once all documents are ready, the online GST REG-01 application can be submitted through the GST portal. The process involves:
- Filling in business details
- Uploading documents
- Generating OTP-based verification
Upon successful submission, an Application Reference Number (ARN) is generated, which is used to track the status.
Verification by the GST Officer (Days 7–14)
The GST consultancy services review the submitted details. If everything is in order, your registration is approved. If additional information is required, the officer issues a GST REG-03 notice requesting clarification.
You must respond within 7 days using GST REG-04. Delayed responses can result in rejection.
GSTIN Issuance (Day 14 or earlier)
Upon approval, the government issues a 15-digit GSTIN and a registration certificate.
From this point onward, the business is legally required to:
- Collect GST
- Issue GST-compliant invoices
- File GST returns regularly
- Maintain books according to GST rules
Understanding Post-Registration Responsibilities
After GSTIN issuance, businesses must complete a few immediate steps with the GST registration consultant:
- Activate GST login credentials
- Enrol for e-way bill (if applicable)
- Update billing software with GSTIN
- Start issuing tax invoices
This ensures readiness for upcoming filing deadlines.
Monthly & Quarterly GST Filing Timeline
GST returns depend on the taxpayer category, turnover, and scheme opted for. Below is a simple timeline:
GSTR-1 (Outward Supplies Return)
- Monthly filers: Due on the 11th of every month for the previous month’s sales.
- Quarterly filers under QRMP: Due on the 13th of the month following the quarter.
GSTR-1 contains details of all outward supplies, which your buyers use to claim ITC.
GSTR-3B (Summary Return & Tax Payment)
- Monthly filers: Due on the 20th of every month.
- QRMP (Quarterly):
- Tax payment through PMT-06 by the 25th of the next month
- Quarterly return filing by the 22nd or 24th of the month following the quarter (varies by state)
GSTR-3B includes tax liability calculation, ITC claims, and net payment details.
Additional Returns Based on Business Category
a. CMP-08 (Composition Scheme)
- Filed quarterly by the 18th of the month after each quarter.
b. GSTR-5 / 5A (Non-resident taxable persons & OIDAR)
- Filed monthly by the 20th of next month.
c. GSTR-6 (Input Service Distributors)
- Due on the 13th of every month.
Each return type has specific data requirements, so timely record-keeping is crucial.
Annual GST Compliance Timeline
GSTR-9 (Annual Return)
Applicable for businesses with a turnover above the threshold.
- Due date: 31st December following the financial year.
This return summarises all monthly/quarterly filings.
GSTR-9C (Reconciliation Statement)
Applicable to businesses exceeding the audit threshold.
- Also due on 31st December.
It reconciles your books with GST returns and must be certified by a professional.
Why Following the GST Timeline Matters?
Maintaining compliance with GST timelines ensures:
- Avoidance of penalties and interest
- Smooth ITC flow
- Accurate financial reporting
- Higher credibility with regulatory bodies
- Hassle-free business expansion
Late filing not only triggers financial penalties but may also block your input tax credit, directly impacting cash flow.
How Professional Consultants Simplify GST Compliance?
Handling GST procedures in-house can be time-consuming and error-prone, especially for businesses with high transaction volumes. Professional GST advisory services help by:
- Ensuring error-free GST registration
- Monthly/quarterly returns preparation
- ITC reconciliation

Final Thoughts
Navigating the journey from GST registration to filing deadlines becomes significantly easier when you clearly understand each step and stay ahead of compliance schedules. A structured approach not only prevents penalties but also boosts financial efficiency and peace of mind.
