GST Changed Everything — And Many Still Don’t Understand It
The Goods and Services Tax replaced 17 different central and state taxes in 2017. For consumers, it simplified the tax structure. For businesses, it created a new compliance ecosystem. Seven years later, many small business owners — freelancers, shop owners, consultants, manufacturers — still have fundamental misconceptions about how GST works, what they need to pay, and how to avoid penalties.
The Basics: When Do You Need to Register?
You must register for GST if your annual turnover exceeds ₹40 lakh (for goods) or ₹20 lakh (for services) — these are the 2026 thresholds. In some special category states, the limits are lower. If you operate in multiple states, you need a separate GST registration for each state. If you sell through e-commerce platforms like Amazon, Flipkart, or Meesho, registration is mandatory regardless of your turnover — even if you earn just ₹1,000 per month from the platform.
The 5 GST Rates — Which One Applies to You?
GST has five main rates: 0% (essential items — rice, wheat, fresh vegetables, healthcare services), 5% (basic goods, restaurants without AC, some textile products), 12% (computers, processed foods, hotel stays ₹1,000-₹7,500), 18% (most services, electronics, consumer goods — this is the most common rate), and 28% (luxury goods, cars above ₹10 lakh, tobacco, gambling). Your product or service’s HSN code (for goods) or SAC code (for services) determines your applicable rate.
Input Tax Credit: The Part That Saves You Money
This is the most powerful — and most misunderstood — part of GST. When you pay GST on your purchases (raw materials, office supplies, services), you can claim that amount back against the GST you collect from your customers. You only pay GST on the value you added, not on the entire transaction value. For example: you buy raw material for ₹1,000 and pay 18% GST = ₹180. You sell the finished product for ₹1,800 and collect 18% GST = ₹324. Your GST payable to the government = ₹324 – ₹180 = ₹144. The ₹180 is your Input Tax Credit.
To claim ITC, your supplier must have filed their GST return and the purchase must appear in your GSTR-2B. This is why buying from registered suppliers matters — if your vendor doesn’t file, you lose the credit.
GST Returns: What You Need to File
For most small businesses under the regular scheme: GSTR-1 (outward supplies) filed monthly or quarterly, and GSTR-3B (summary return and payment) filed monthly. For businesses with turnover under ₹1.5 crore, the Composition Scheme allows quarterly filing with a flat tax rate (1-6% of turnover) and no ITC — simpler but you cannot collect GST from customers.
The Penalties That Catch People Off Guard
Late filing: ₹50 per day (₹20 for nil returns) up to a maximum of ₹10,000. Interest on unpaid tax: 18% per annum. Not registering when required: penalty of 10% of tax due (minimum ₹10,000) or 100% of tax due if fraud is proven. The safest approach is to use an accountant or GST software (ClearTax, Zoho Books, Tally) and file on time — the penalty cost almost always exceeds the software cost.
