Goods and Services Tax (GST)

Start with what you already know

Walk into any shop — a chemist, a mobile store, a restaurant — and look at your bill. At the bottom, you will see a line: GST @ 5% or GST @ 12% or GST @ 18%. That extra amount is not pocketed by the shopkeeper. It goes to the government. But why is there a separate tax called GST, and not just "sales tax" or "VAT" like before?

The answer lies in a simple problem: before GST, every state had its own tax system. A truck carrying goods from Maharashtra to Karnataka would be stopped at checkposts, pay entry tax, octroi, and state VAT — each time adding cost and delay. GST was designed to make India one unified market.

The precise meaning

Let me unpack each part of that definition.

Comprehensive — It replaced a dozen central and state taxes (excise duty, service tax, VAT, octroi, entry tax, luxury tax, etc.) with a single tax.

Multi-stage — A product passes through several stages: raw material → manufacturer → wholesaler → retailer → consumer. GST is collected at every stage where value is added.

Destination-based — The tax revenue goes to the state where the goods are consumed, not where they are produced. If a car is made in Gujarat but sold in Bihar, Bihar gets the GST.

Value addition — This is the key idea. A manufacturer buys steel for ₹100, pays 18% GST (₹18). He uses the steel to make a machine and sells it for ₹200. He collects 18% GST (₹36) from the buyer. But he does not pay ₹36 to the government — he pays only ₹18 (₹36 minus the ₹18 he already paid on steel). This is called Input Tax Credit (ITC).

How GST works: a simple chain

Imagine a wooden chair.

1. Logger sells timber to a furniture maker for ₹1,000. GST @ 18% = ₹180. Logger deposits ₹180 with the government.

2. Furniture maker uses the timber, adds value (labour, design), and sells the chair to a wholesaler for ₹2,000. GST on sale = ₹360. But he claims ITC of ₹180 (the tax he already paid on timber). He deposits only ₹180 (₹360 − ₹180).

3. Wholesaler sells to a retailer for ₹3,000. GST = ₹540. ITC = ₹360. Deposits ₹180.

4. Retailer sells to you, the consumer, for ₹4,000. GST = ₹720. ITC = ₹540. Deposits ₹180.

Total tax collected = ₹180 + ₹180 + ₹180 + ₹180 = ₹720 — exactly 18% of the final price ₹4,000.

Why GST matters for the economy

Removed cascading — Earlier, a product bore "tax on tax". A study by the National Institute of Public Finance and Policy estimated that cascading added 25–30% to the final price of many goods. GST removed that.

Made India a common market — Before GST, a truck moving from Delhi to Chennai spent 60–70 hours at state borders in paperwork. After GST, interstate checkposts were dismantled. Logistics costs fell.

Increased tax base — Because every business wants ITC, they must file returns and show purchases from registered suppliers. This pulls informal businesses into the tax net.

Simplified compliance — Instead of filing separate returns for excise, service tax, and VAT, a business files one GST return.

The three-tier structure

GST in India is not a single rate. It has three components:

For a sale within the same state (say, a shop in Delhi selling to a customer in Delhi), the total GST is split equally: 9% CGST + 9% SGST = 18% total.

For a sale across states (Delhi to Mumbai), only IGST is charged (18%). The central government collects it and later transfers the state's share to Maharashtra (the destination state). …

Fiscal Deficit: What It Really Means

Think of your household budget. If your monthly expenses exceed your income, you have a shortfall. You cover it by borrowing from someone — a friend, a bank. That shortfall is your personal "deficit."

Now scale that up to the entire country. The government earns money (mostly through taxes) and spends money (on roads, salaries, defence, subsidies). When the government's total spending exceeds its total non-borrowed income, it runs a fiscal deficit. It's the gap the government must fill by borrowing.

The Precise Definition (NCERT Class 12)

The NCERT Macroeconomics textbook defines fiscal deficit as:

Fiscal Deficit = Total Expenditure − Total Receipts excluding borrowings

Let's unpack that. "Total Receipts excluding borrowings" means all the money the government gets without going into debt — mainly tax revenue and non-tax revenue (like fees, dividends from public sector companies, etc.). Borrowings are not counted as "receipts" here because they are the source of finance for the deficit, not income.

So the formula is:

Where:

• Total Expenditure = Revenue Expenditure (day-to-day running costs) + Capital Expenditure (building assets like highways, dams)
• Revenue Receipts = Tax revenue + Non-tax revenue (fees, fines, dividends)
• Non-debt Capital Receipts = Money from selling government assets (disinvestment), loan recoveries — these don't create debt

The fiscal deficit is not the same as "total borrowing." It is the amount that must be borrowed. In practice, the government covers this gap by:

• Borrowing from the market (selling bonds)
• Borrowing from the RBI
• Drawing down cash balances

Why Does It Matter?

A fiscal deficit isn't automatically bad — it depends on why it exists and how it's financed.

When it's good: If the government borrows to build a national highway network, that creates jobs, boosts transport, and generates future tax revenue. The deficit is an investment.

When it's bad: If the deficit is caused by wasteful subsidies or paying salaries without any productive outcome, and the government keeps borrowing year after year, it piles up debt. Future generations must repay it. Large deficits can also fuel inflation if the RBI prints money to finance them.

A Simple Diagram (in words)

Imagine a vertical bar representing total government expenditure. Below it, a shorter bar represents total receipts (excluding borrowings). The gap between the top of the expenditure bar and the top of the receipts bar is the fiscal deficit. That gap is filled by borrowings.
