✅ GST Registration in 3 Days – Who Can Get It, What’s the Limit & When You Need to Exit

From 1st November 2025, GST registration has become faster for small businesses. A new rule allows GST registration to be approved in just 3 working days — and in many cases, even quicker — without any officer calling or visiting.

This option is available for low-risk businesses. Let’s understand who can apply, how much turnover is allowed, and when someone has to come out of this scheme.

🟢 What is this new rule?

The government brought this in through Notification No. 18/2025. If you apply for GST with proper Aadhaar and documents, and your business is small and simple, the system will approve your registration automatically.

No follow-up, no queries — if you qualify.

✅ Who can use this 3-day GST route?

You can apply under this route if:

• Your monthly GST on sales to other businesses (B2B) is less than ₹2.5 lakh

• You’ve done Aadhaar authentication

• Your PAN/business is not flagged for any GST issues

• You’re not doing risky activities like inter-state or e-commerce in the beginning

This is ideal for:

• Traders, freelancers, small retailers, consultants

• People just starting out

• Home-run businesses or single-shop owners

• Businesses who mostly do B2C sales but a little B2B also

💰 How much turnover is allowed?

This rule talks about tax limit, not turnover. But to help you judge:

GST Rate	Approx Monthly Turnover Allowed	Annual Turnover
18% (services)	₹13.9 lakh	₹1.66 crore
12% (trading)	₹20.8 lakh	₹2.5 crore
Mixed business	₹16–17 lakh	₹2.0 crore approx.

So if your total business (mainly B2B) is up to ₹1.5–2.5 crore/year, you’ll usually fit in this scheme.

🛍️ What about B2C sales?

Good news — sales to normal customers (B2C) are not counted in the ₹2.5 lakh/month limit.

So you can do any amount of B2C. The limit is only on GST charged to other registered businesses.

But still, if your total turnover or B2C value gets very high, the GST system might check your application more carefully.

📊 Example – How it works

Imagine you run a textile business in Hyderabad.

• You sell ₹18 lakh/month to B2B @ 5% GST → ₹90,000

• You sell ₹7 lakh/month to B2C @ 5% GST → ₹35,000Total GST = ₹1.25 lakh/month✅ You qualify for fast registration

Now say your B2B sales go up to ₹60 lakh/month → ₹3 lakh GST❌ You cross the ₹2.5 lakh/month limit➡️ You have to exit the scheme (explained below)

🔁 When do you have to come out of this scheme?

There are two ways this happens:

1️⃣ System removes you automatically:

• You cross the ₹2.5L GST limit (B2B sales)

• You change your business model (e.g. start inter-state or e-commerce)

• Your GST return filings have problems or mismatches

In this case, the department may issue Form REG-33 and move you out of the fast-track route.

2️⃣ You exit voluntarily (recommended):

If your business grows, and you now expect to cross the limit, you can file Form REG-32 and exit politely.No fine, no issues — just good compliance.

Your GSTIN will continue. Only the “fast approval” tag is removed. Next time if you make amendments, you may face regular verification.
