GST for beginners comes down to one idea: Goods and Services Tax (GST) is a single indirect tax on the supply of goods and services in India, collected in stages and passed on to the buyer. If you run a business, you collect it on sales, subtract the GST you paid on purchases, and send the difference to the government. If you are a consumer, you pay it inside the price of what you buy.<\/p>\n

This guide explains how GST works, who must register, how returns are filed and where beginners usually go wrong. Rates, thresholds and due dates change, so wherever a figure matters, check the current value on the official GST portal before you act.<\/p>\n

What Is GST and How Does It Work?<\/h2>\n

GST is a destination based indirect tax that replaced a set of older taxes such as VAT, service tax and excise duty with one framework. It is charged on each sale in a supply chain, but every business in the chain can claim back the GST it already paid on its inputs. That claim is called input tax credit, and it is why the tax falls on the final consumer and not on each business in the middle.<\/p>\n

The law itself sits in the Central GST Act and the state GST Acts. You can read the statute text for these Acts on India Code, the government repository of central laws<\/a>. Policy and administration of the tax come under the Government of India, and the Ministry of Finance<\/a> is the starting point for official announcements.<\/p>\n

Think of GST as a relay. A manufacturer sells to a wholesaler, the wholesaler sells to a retailer and the retailer sells to you. Each seller adds GST to the invoice, then deducts what it paid on its own purchases. Only the value each seller adds is taxed at that step.<\/p>\n

What Are CGST, SGST and IGST?<\/h2>\n

CGST, SGST and IGST are the three components of GST. Which ones appear on an invoice depends on whether the sale stays inside one state or crosses a state border.<\/p>\n\n\n\n\n\n\n\n\n
Component<\/th>\nFull name<\/th>\nWhen it applies<\/th>\nWho collects it<\/th>\n<\/tr>\n<\/thead>\n
CGST<\/td>\nCentral Goods and Services Tax<\/td>\nSale within one state<\/td>\nCentral government<\/td>\n<\/tr>\n
SGST<\/td>\nState Goods and Services Tax<\/td>\nSale within one state<\/td>\nState government<\/td>\n<\/tr>\n
UTGST<\/td>\nUnion Territory GST<\/td>\nSale within a union territory without its own legislature<\/td>\nUnion territory administration<\/td>\n<\/tr>\n
IGST<\/td>\nIntegrated Goods and Services Tax<\/td>\nSale between two states, and imports<\/td>\nCentral government, shared with the destination state<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

On a sale within one state, the total rate is split equally between CGST and SGST. A sale at a total rate of 18% therefore shows 9% CGST and 9% SGST. On a sale to another state, the same 18% appears as IGST alone.<\/p>\n

What Are the GST Rates in India?<\/h2>\n

GST rates in India depend on the type of goods or services, and the government revises the slabs and the items under each slab from time to time. The older structure had slabs of 0%, 5%, 12%, 18% and 28%, with essentials such as food grains taxed at a low rate or exempt. Because the structure has been revised since, do not rely on any list printed in an article, including this one.<\/p>\n

The reliable way to find the rate for your product is the HSN code (for goods) or SAC code (for services), which is a standard classification number. Look up your code and the rate attached to it on the official GST portal, and use that rate on your invoices. If you are a consumer, the rate is shown on the invoice you receive.<\/p>\n

For learning purposes, the examples in this article use round illustrative rates. They are not current rates for any real product.<\/p>\n

Who Needs to Register for GST?<\/h2>\n

You must register for GST when your aggregate turnover crosses the threshold set for your type of supply and your state, or when your activity makes registration compulsory whatever your turnover. Registration is done online through the GST portal and gives you a 15 digit number called the GSTIN.<\/p>\n\n\n\n\n\n\n\n\n\n\n
Situation<\/th>\nRegistration position<\/th>\n<\/tr>\n<\/thead>\n
Turnover below the threshold, selling only inside your state<\/td>\nRegistration is usually not required, but you may register voluntarily<\/td>\n<\/tr>\n
Turnover above the threshold<\/td>\nRegistration is required<\/td>\n<\/tr>\n
Special category states<\/td>\nA lower threshold applies<\/td>\n<\/tr>\n
Selling through an e-commerce operator<\/td>\nRegistration is generally required whatever your turnover<\/td>\n<\/tr>\n
Supplying goods or services between states<\/td>\nRules differ by type of supply, so check the portal<\/td>\n<\/tr>\n
Casual or non-resident taxable persons<\/td>\nRegistration is required before you start supplying<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The figures quoted most often are Rs 20 lakh a year for general category states and Rs 10 lakh a year for special category states. Thresholds differ between goods and services and between states, and they can be revised, so confirm the current figure for your case on the GST portal.<\/p>\n

What Documents Do You Need to Register?<\/h3>\n

Registration typically needs your PAN, proof of business address, identity and photographs of the proprietor or partners, and bank account details. If you want to know why PAN and identity checks sit behind so many financial processes, this explainer on why a PAN card matters in banking<\/a> covers the basics. Your KYC (know your customer) details must also be in order, and why KYC is mandatory in India<\/a> explains what that involves.<\/p>\n

Should You Register Even If You Are Below the Threshold?<\/h3>\n

You can, and some small sellers do. The benefit is that you can claim input tax credit and sell to larger buyers who prefer GST invoices. The cost is that you take on regular return filing and record keeping, and you must charge GST on your sales, which can make your prices less competitive against unregistered sellers.<\/p>\n

What Is Input Tax Credit and How Is It Calculated?<\/h2>\n

Input tax credit (ITC) is the GST you paid on business purchases, which you subtract from the GST you collected on sales. Only the net amount goes to the government. To claim it, you need a valid tax invoice, the purchase must be for business use, and the supplier\u2019s details generally need to appear in your records matched with the GST portal.<\/p>\n

Here is a worked example. All figures are illustrative, and the 18% rate is an assumption for learning, not a current rate.<\/p>\n\n\n\n\n\n\n\n\n\n
Step<\/th>\nCalculation<\/th>\nAmount<\/th>\n<\/tr>\n<\/thead>\n
Sales for the month, before GST<\/td>\nGiven<\/td>\nRs 1,00,000<\/td>\n<\/tr>\n
GST collected on sales<\/td>\n18% of Rs 1,00,000<\/td>\nRs 18,000<\/td>\n<\/tr>\n
Purchases for the month, before GST<\/td>\nGiven<\/td>\nRs 60,000<\/td>\n<\/tr>\n
GST paid on purchases (input tax credit)<\/td>\n18% of Rs 60,000<\/td>\nRs 10,800<\/td>\n<\/tr>\n
GST payable to the government<\/td>\nRs 18,000 minus Rs 10,800<\/td>\nRs 7,200<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Because this is a sale within one state, the Rs 7,200 is paid as Rs 3,600 CGST and Rs 3,600 SGST in this simplified case. In practice, credit of one type is used in a set order against the matching liability, so your actual split on the portal can differ.<\/p>\n

Notice the cash flow effect. You collect Rs 1,18,000 from your customer but only Rs 7,200 of the GST in it is yours to pay, provided the customer pays you on time. If a customer pays late and your return is due, you may have to pay the tax out of your own funds before the money arrives.<\/p>\n

If late customer payments leave you covering tax and expenses on a credit card, the interest can grow faster than the gap itself. BillCut can help you look at converting that card balance into structured monthly EMIs, and you can see how it works on the BillCut website<\/a>.<\/p>\n

What Is the GST Composition Scheme?<\/h2>\n

The Composition Scheme is an optional scheme for small taxpayers under which you pay tax as a fixed percentage of turnover instead of calculating tax on each sale. It reduces paperwork, but you give up input tax credit and cannot collect GST from your customers on your invoices. The turnover limit and the percentage depend on the type of business and are set by the government, so check the GST portal for the current terms.<\/p>\n\n\n\n\n\n\n\n\n\n\n
Feature<\/th>\nRegular scheme<\/th>\nComposition scheme<\/th>\n<\/tr>\n<\/thead>\n
How tax is calculated<\/td>\nOn each sale, minus input tax credit<\/td>\nFixed percentage of turnover<\/td>\n<\/tr>\n

Best suited to<\/td>\nBusinesses with large purchases or business buyers<\/td>\nSmall sellers with low purchases and mostly consumer buyers<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

To compare the two, use an illustrative case. Assume a shop with Rs 50,00,000 annual turnover and a composition rate of 1%. Under the scheme, the tax is 1% of Rs 50,00,000, which is Rs 50,000. Now assume the same shop under the regular scheme sells at an average 5% rate and buys Rs 30,00,000 of goods carrying 5% GST. Output tax is 5% of Rs 50,00,000, which is Rs 2,50,000. Input credit is 5% of Rs 30,00,000, which is Rs 1,50,000. Net tax is Rs 1,00,000.<\/p>\n

In this made up case the composition scheme costs Rs 50,000 less in tax. The result flips if the shop has heavy purchases or sells mainly to businesses that want credit on their purchases. The numbers are illustrative only, so run your own figures with real rates.<\/p>\n

How Do You File GST Returns?<\/h2>\n

You file GST returns online on the GST portal, reporting your sales, your purchases, the input tax credit you claim and the tax you pay. How often you file depends on your turnover and the scheme you chose, and the options include monthly and quarterly filing. Due dates are set by the government and can be extended, so read the current calendar on the portal.<\/p>\n\n\n\n\n\n\n\n\n
Return type<\/th>\nWhat it reports<\/th>\nWho typically files it<\/th>\n<\/tr>\n<\/thead>\n
Outward supplies return<\/td>\nYour sales invoices for the period<\/td>\nRegular scheme taxpayers<\/td>\n<\/tr>\n
Summary return with tax payment<\/td>\nSummary of sales, credit claimed and tax paid<\/td>\nRegular scheme taxpayers<\/td>\n<\/tr>\n
Composition return<\/td>\nTurnover and tax payable under the scheme<\/td>\nComposition scheme taxpayers<\/td>\n<\/tr>\n
Annual return<\/td>\nFull year summary of sales, purchases and tax<\/td>\nRegistered taxpayers above set limits<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The practical steps are the same each period. Upload or enter your sales invoices, match your purchase records with what the portal shows from your suppliers, work out the net tax, pay it, then submit the return.<\/p>\n

What Happens If You File Late?<\/h3>\n

Late filing usually attracts a late fee and interest on the unpaid tax, and repeated delays can lead to action on your registration. The rates of fee and interest are set under the GST law and revised from time to time, so look at the current amounts on the portal. Filing a return with no sales still counts as a filing, so a nil return is generally required.<\/p>\n

How Does GST Link to Income Tax?<\/h3>\n

GST and income tax are separate taxes. GST is an indirect tax on transactions, while income tax is charged on your profit or income, and the two are administered through different portals. The Income Tax Department<\/a> handles the second. Your GST sales figures and your income tax return should tell a consistent story, because both reflect the same business.<\/p>\n

What Are the Common GST Mistakes Beginners Make?<\/h2>\n

Most beginner errors come from poor records and missed dates, not from the tax rules themselves. These are the ones that cost money most often:<\/p>\n
