GST as the Preferred Tax Structure

GST (Goods and Services Tax) was implemented from 1 July 2017, as per the One Hundred and First Amendment of the Constitution. It subsumed multiple central and state indirect taxes (VAT, service tax, excise, etc.), creating a unified, destination-based, multi-stage tax system.

Recently, in September 2025, the GST Council approved major reforms (“GST 2.0”). Key changes include rationalisation of rate slabs: reducing the number of main slabs, bringing many items down into lower GST bands, and simplifying compliance. The main rate slabs now are 5% and 18% for most items, with a few goods/services under 40% (sin/luxury goods) and some under 0% or exempted categories.

These changes come into effect from 22 September 2025. Essentials like certain food items, condiments, household items, personal care, etc., have seen rate reductions. Also, services like life and health insurance have been moved to 0% GST.

Why GST Is The Preferred Tax Structure: Advantages & Merits

Unified Market & Removal of Tax Cascading

• Pre-GST, there were multiple indirect taxes (VAT, CST, service tax, etc.), and inter-state trade suffered due to checks, state-level barriers, and cascading—tax on tax burdens. GST replaced them with a destination-based single tax system.

• Input Tax Credit (ITC) allows tax paid on purchases and inputs to be set off against output tax, removing cascading. The recent rate rationalisation further reduces distortion by having fewer slabs—many goods now have lower GST rates (5%) reducing cascade.

Simplified Rate Structure & Reduced Complexity:

• Multiple GST slabs earlier (0%, 5%, 12%, 18%, 28%) led to complexity in deciding which item falls under which rate. Classification disputes were common. The new GST 2.0 reduces these to mainly 5% and 18% (plus 40% for sin/luxury), simplifying classification. 

• Simpler slabs reduce compliance cost, reduce confusion among businesses and consumers, and facilitate easier enforcement. Fewer categories mean fewer mistakes in tax rate application, fewer litigations/disputes.

Consumer Relief & Inflation Control

• Rate cuts on essential goods help reduce cost of living. For example, many food items, life and health insurance, milk and related dairy products are now taxed at lower rates—some items even exempted. 

• This helps in controlling inflation by reducing tax burden on consumption. Such reductions especially benefit lower- and middle-income households. The government’s move to rationalize GST rates can have a disinflationary effect.

Better Compliance & Transparency:

• GST’s mechanism of electronic invoices, input tax credit traceability, required documentation, and return filing system promotes transparency. Businesses must maintain proper invoices to claim credit. This helps reduce evasion and improve tax base. 

• The rationalization of slabs reduces ambiguity, so fewer disputes and clearer compliance. Also, the recent reforms clarify when new rates apply, how advance payments and invoicing should be treated, etc. 

Ease of Doing Business & Administrative Efficiency:

• Eliminating multiple tax levies across states reduces friction in movement of goods. Interstate checkpoints and state-wise differences have earlier hampered logistics. GST streamlines transport, lowers logistical costs. 

• Recent rate rationalisation simplifies compliance, returns, classification, and accounting systems. Fewer slabs mean returns are simpler, reduced accounting complexity, fewer misclassifications. This is especially helpful for MSMEs and small businesses.

Revenue Stability & Predictability:

• A broader tax base reduces volatility. Since GST applies to a wide array of goods and services and is collected at all points of supply, government gets more predictable indirect tax inflows.

• Simplification and rationalization of slabs helps the government anticipate revenue better. Though rate cuts reduce tax per unit, higher consumption volume, easier compliance, and reduced evasion may offset revenue loss. Also, having “sin/luxury” items taxed heavily (40%) ensures revenue from discretionary consumption.

Encouraging Consumption & Demand:

• Lower GST on several consumer goods increases disposable incomes and reduces final prices. This encourages spending, which helps boost demand in the economy.

• In sectors like automobiles, electronics, and household appliances, reduction from higher slabs to 18% has potential to stimulate sales. Everyday essentials becoming cheaper helps middle class. The timing (just before festive seasons) also helps.

Fairness & Equity:

• Essentials taxed lower or exempted helps poorer households. Tax structure aligned so that consumers pay less tax on basic items, more on luxury/sin goods. The recent reform emphasizes this—luxury/sin goods now taxed at 40%, while essentials move down.

• The destination-based nature of GST ensures consumers ultimately bear the tax in the place where consumption happens—not where goods are produced—so states receive revenue corresponding to consumption by their residents.

Integrated National Market:

• GST unified the market across India. Previously, state borders meant different VAT rates, CST, entry taxes, etc. Now, goods move more freely without special checks. This integrates markets, reduces cost of doing business, fosters competition.

• The recent changes further strengthen this integration by aligning rates across a broad range of goods—reducing the rate differential between states and simplifying interstate trade.

Implications of Recent Rate Changes (GST 2.0 Reforms)

These reforms (effective 22 September 2025) amplify many of the merits above, but also involve adjustments and challenges. Key implications:

A. Consumer Price Reductions

• Many everyday items (food, household goods, certain beauty/personal care, insurance, etc.) now taxed at 5% or exempted. This directly lowers consumer expenses. There is an expected relief in inflation. 

• Automobiles (especially smaller cars) and electronics also see GST fall from 28% to 18% in many cases. Reductions in logistics costs via reduced tax on transport inputs also help. 

B. Simplification & Lower Disputes

• With fewer slabs, fewer classification ambiguities. Items which earlier fell in the awkward 12% or 28% band now either moved up or down. This reduces disputes over what rate applies.

• Clarity over “invoice timing, payment receipts” with respect to old/new rates (i.e. if payment received before the 22nd, old GST rate applies). This helps businesses plan transitions. 

C. Business Costs, Margins, and Investment

• For companies producing goods in categories now taxed lower, costs may reduce (if they can claim input credits, etc.), potentially improving margins or passing on benefits. For companies whose products moved to higher rates (e.g. some luxury/sin goods), cost increases may happen.

• Investment in manufacturing, consumer goods, MSMEs likely to get a boost, because demand may rise with lower tax on essentials and broad consumption items.

Challenges & Transitional Issues:

• Businesses need to update billing/invoicing systems, stock labeling, pricing strategies to reflect new GST rates. Old inventory unsold may need re-pricing, re-labelling. 

• Some goods moved up in tax slab may get pushback from industry. There is risk of inflation in some sectors if costs are passed on.

• Foreign investors and exporters will need to adjust to new compliance demands, especially with changes in rate application based on payment or invoice dates.
