What Online Sellers in Purnea Must Know About GST Compliance in 2025

The e-commerce landscape is booming in Bihar, with thousands of sellers from Purnea, Katihar, Araria, and Kishanganj joining platforms like Amazon, Flipkart, Meesho, and JioMart. But along with opportunity comes responsibility—especially in terms of tax compliance.

GST (Goods and Services Tax) rules for online sellers are evolving, and the penalties for non-compliance can be serious. Whether you’re a small manufacturer trying to expand your market or a local trader just starting online sales, understanding e-commerce GST in Bihar is now critical.

In this guide by Avyud Consultancy, your trusted local advisor in Purnea, we simplify key GST provisions for online sellers so that you can focus on growth—not paperwork.

Why GST Matters for E-Commerce Sellers

Unlike offline sellers, e-commerce vendors have to follow additional GST rules. This includes mandatory registration, reverse charge mechanism in some cases, tax collected at source (TCS) by aggregators, and strict invoicing requirements.

Without proper understanding, even a small oversight can lead to:

Delays in payments from aggregators
GST portal errors
Penalties or late fees
Blocking of input tax credit (ITC)

Who Must Register Under GST? — Thresholds in Bihar

As per current rules (2025 update):

Business Type	Annual Turnover	GST Registration Needed?
Bihar-based e-commerce seller	Any amount (even ₹1)	Yes (Mandatory)
Offline trader in Bihar	Above ₹40 lakhs (goods)	Yes
Service providers	Above ₹20 lakhs	Yes

👉 Key Insight:
Even if your online business makes just ₹10,000 in a year, GST registration is mandatory because you’re selling via a third-party platform (Section 24 of CGST Act).

Invoicing Rules Every Online Seller Must Follow

GST-compliant invoicing isn’t optional for online sellers—it’s mandatory and frequently verified by e-commerce platforms and GSTN.

Here’s what your invoice must include:

Your GSTIN
Buyer details (if B2B)
HSN/SAC codes for your products/services
Tax rate and breakup (CGST/SGST or IGST)
Unique invoice number
Signature (digital or manual)

✅ Pro Tip from Avyud:
Create a digital invoice template with auto-calculations. Avyud Consultancy can help you set it up based on your product type.

TCS (Tax Collected at Source) by E-Commerce Aggregators

If you sell through Amazon, Flipkart, Meesho, etc., they will deduct 1% TCS on the sale value and deposit it with the government. This amount will reflect in your GST portal (GSTR-2A) and must be reconciled while filing monthly returns.

📝 Checklist for TCS Compliance:

Link your aggregator account with your GSTIN
Download TCS statements monthly
Match it with your sales report
Reconcile before filing GSTR-3B and GSTR-1

Penalties for Non-Compliance

Here are a few risks if you ignore GST obligations:

Mistake	Penalty/Consequences
Not registering	₹10,000 or 100% of tax due
Late filing of returns	₹50–₹200 per day + interest
Wrong GSTIN on invoice	ITC denial and penalties
No TCS reconciliation	Notice from GST Department

Real Case from Purnea: How a Local Seller Avoided a ₹25,000 Penalty
