Do you actually need a GST number?

Many new business owners panic and apply for a GST number on day one, not realizing that once you get it, you are locked into monthly paperwork. Before you start the online GST registration process, you need to check if you actually cross the government's legal limits.

The Mandatory GST Registration Turnover Limit

The Indian Government has set a clear mandatory GST registration turnover limit based on what you sell and where your business is located. If your total sales in a single financial year cross these limits, getting a GSTIN is legally required:

For Selling Goods: If your annual turnover exceeds ₹40 Lakhs (or ₹20 Lakhs in special category states like Assam, Uttarakhand, and Himachal Pradesh).
For Selling Services: If your annual turnover exceeds ₹20 Lakhs (or ₹10 Lakhs in special category states).

When the limit does NOT matter

You must complete the online GST registration process immediately—even if your sales are just ₹100—if you fall into these categories:

You sell products on e-commerce platforms like Amazon, Flipkart, or Swiggy.
You sell goods to a customer who lives in a different state (Inter-state supply).
You are an exporter receiving payments from outside India.

How to save money with GST

While GST sounds like an extra expense, it is actually designed to save businesses money through a system called Input Tax Credit. Understanding how to claim Input Tax Credit is the secret to increasing your profit margins.

What is Input Tax Credit (ITC)?

When you buy raw materials, office laptops, or pay for professional services, you pay GST to your supplier. When you sell your final product to a customer, you collect GST from them. ITC allows you to subtract the GST you already paid from the GST you collected. You only pay the government the difference.

To successfully claim Input Tax Credit, your accountant must ensure that your supplier has correctly uploaded their sales invoice to the GST portal. If they fail to upload it, you cannot claim the credit, and you lose that money. This is exactly why Validraft’s monthly filing service includes rigorous ITC matching—we hunt down your missing credits so you don't overpay taxes.

Gathering Your Paperwork

The government portal is incredibly strict. A single spelling mistake between your PAN card and your rental agreement will result in a "Show Cause Notice" and delay your application by weeks. Here is the exact list of documents required for GST registration based on your business type.

For Sole Proprietors

The simplest structure. The business and the owner are considered the same entity.

Owner's PAN Card
Aadhaar Card & Photo
Office Electricity Bill
NOC from Property Owner
Cancelled Cheque

For Private Limited

The company gets its own GST number. The directors act as authorized signatories.

Company PAN & Certificate
PAN/Aadhaar of all Directors
Board Resolution Letter
Office Electricity Bill & NOC
Company Bank Statement

For Partnerships/LLP

The firm holds the GST number, and the designated partners must authorize the filings.

Firm PAN Card
Partnership Deed or LLP Cert.
PAN/Aadhaar of all Partners
Office Electricity Bill & NOC
Firm Cancelled Cheque

Note: The documents required for GST registration must be clear, legible, and the office address proof must not be older than 2 months.

Monthly Filings & The Danger Zone

Getting your 15-digit GSTIN is the easy part. The real challenge is the monthly compliance. Once your online GST registration process is complete, you enter a strict cycle of government deadlines.

The Golden Rule of GST

Even if you made ZERO sales this month, you must log in and file a "NIL Return." You cannot simply ignore the portal.

If you miss a deadline, the government applies a brutal GST return filing penalty. The late fee is ₹50 per day for regular returns (and ₹20 per day for NIL returns). This penalty is calculated automatically by the portal and cannot be waived by any officer. If you forget to file for six months, not only will you accumulate massive daily fines, but the government will proactively suspend your GST number and freeze your corporate bank account.

How to Cancel Your GST Number

If you decide to close your business or your turnover drops below the mandatory GST registration turnover limit, you cannot just stop filing returns. You must formally apply for GST Cancellation.

To do this, our experts will ensure all your pending monthly returns are filed, clear any outstanding tax dues, and submit Form GST REG-16. Once the officer accepts the cancellation, you have three months to file a final closing return (GSTR-10). Failing to file GSTR-10 carries a massive ₹10,000 flat penalty.

Frequently Asked Questions

Still have doubts? Here are the most common questions founders ask us about GST.

What is the government fee for the online GST registration process?

The Indian Government charges ₹0 to issue a GST number. The portal is free to use. You only pay Validraft a professional fee for collecting your documents, drafting the application, answering government notices, and ensuring the application is approved without errors.

Can I claim Input Tax Credit on my personal expenses?

No. You can only claim Input Tax Credit on goods and services used exclusively "in the course or furtherance of business." Furthermore, Section 17(5) of the GST Act strictly blocks ITC on certain business expenses, like buying a car for the director, employee food/beverages, and club memberships.

What is the GST Composition Scheme?

It is a simpler scheme for small businesses with a turnover under ₹1.5 Crore. Instead of complex monthly filings, you pay a flat GST rate (e.g., 1% for traders, 5% for restaurants) out of your pocket quarterly. However, composition dealers cannot claim Input Tax Credit and cannot sell goods to other states.

How long does it take to get the GSTIN?

If all the documents required for GST registration are perfect, the government typically issues the GST Certificate and 15-digit GSTIN within 3 to 7 working days. If the officer raises a query regarding your office address, it may take an additional week to file a clarification.

Is there a maximum cap on the GST return filing penalty?

Yes, but it is very high. The GST return filing penalty (late fee) for GSTR-1 and GSTR-3B is capped at ₹10,000 per return. However, if you owe taxes, the government will also charge you 18% per annum interest on the unpaid tax amount, which has no cap.

Can I have multiple GST numbers on one PAN card?

Yes. In fact, if your business has physical offices or warehouses in different states, you are legally required to obtain a separate GSTIN for every state where you operate. You can also voluntarily get multiple GSTINs in the same state if you run distinct business verticals.
