GST Rate Cuts Losing Impact as Inflation Rises, Congress Claims

Congress Says GST Benefits Are Being Eroded by Inflation

The Congress has claimed that the benefits of Goods and Services Tax (GST) rate cuts introduced in September 2025 are being increasingly offset by rising commodity prices.

Congress general secretary in-charge of communications Jairam Ramesh said on September 21 that the impact of the GST reductions was being neutralised by what he described as “galloping inflation”. He argued that the tax cuts had produced mixed results in terms of boosting consumption.

Ramesh made the comments while referring to a report that indicated prices of several products, including food items, consumer goods and automobiles, had increased after the initial impact of GST rationalisation.

What Did the Congress Claim?

Ramesh argued that the GST rate reductions announced in September 2025 had initially been presented as a major measure to support consumers and economic activity.

According to his comments, however, the impact has differed considerably between product categories.

He pointed to automobiles as an area where sales benefited from the GST changes, while saying apparel sales did not show the same response. He also claimed that prices of several consumer goods had moved close to their pre-GST-cut levels within a year without a corresponding meaningful increase in consumption.

These are Congress's political and economic claims; they do not by themselves establish the overall effect of GST reform on inflation or consumption.

GST Rate Rationalisation Was Introduced in September 2025

The GST changes referred to by Congress were introduced in September 2025 and involved reductions in tax rates across a range of goods and services.

Government data presented to Parliament in March 2026 said GST rates on several categories had been reduced from 28% to 18%, from 18% to 12% or 5%, and from 12% to 5% or nil.

The objective of such reductions was to lower the tax burden on selected products and improve affordability, while also supporting consumption and economic activity.

However, the final price paid by consumers depends on more than the GST rate. Input costs, commodity prices, retailer margins, demand conditions, exchange rates and the extent to which businesses pass tax changes through to consumers can all affect retail prices.

Research Shows GST Price Transmission Has Varied

An NIPFP working paper published in 2026 examined consumer-price movements before and after the GST rate restructuring.

The research found that the impact differed significantly between product categories. Several food, household and personal-care products recorded increases in CPI after the GST restructuring, suggesting incomplete transmission of GST reductions in those categories.

At the same time, several consumer durables, including motor vehicles, bicycles, tyres and tubes, air conditioners and selected household appliances, recorded declines in CPI values, indicating relatively stronger price transmission in some discretionary and higher-value goods.

The findings therefore suggest that the relationship between GST reductions and consumer prices is not uniform across the economy.

Inflation Can Offset the Benefit of a Tax Cut

A reduction in GST does not necessarily guarantee that retail prices will remain lower indefinitely.

If input costs or market prices rise after a tax reduction, businesses may face higher costs that partly offset the reduction in tax.

For example, increases in raw-material prices, transportation expenses, wages or imported-input costs can influence the final price of a product.

The government told Parliament in March that currency depreciation and higher global raw-material prices could put upward pressure on input costs in some sectors, although the eventual effect depends on several factors, including international price pass-through and domestic market conditions.

Consumption Response Has Been Uneven

One of the central issues raised by Congress is whether GST reductions have translated into stronger consumption.

Ramesh argued that consumption has not become buoyant across income groups and that private investment remains weak. He also claimed that real wages are declining.

The broader question is important because GST reductions are expected to have a greater economic impact if businesses pass on the savings and consumers respond by increasing purchases.

However, consumption depends on several factors beyond taxation, including household income, employment, inflation expectations, borrowing costs and consumer confidence.

Automobiles and Apparel Show Different Outcomes

The Congress has specifically contrasted the automobile and apparel sectors.

According to Ramesh, automobile sales benefited from the GST changes, while apparel sales did not show the same response.

Different sectors can respond differently to tax changes because consumers have varying levels of price sensitivity.

Automobiles are high-value purchases where even a modest change in the final price can affect the affordability of a vehicle. Apparel, by contrast, includes a wide range of products and price points, and purchasing decisions may depend on income, seasonal demand and broader household spending.

Why GST Cuts Do Not Always Translate Into Permanent Price Reductions

There is an important distinction between a lower tax rate and a permanently lower retail price.

When GST is reduced, the tax component of a product's price can fall. But the overall retail price can subsequently change because of movements in the underlying cost of producing or selling the product.

This means consumers may initially benefit from a tax reduction but later see some of that benefit absorbed by increases in raw-material costs or other expenses.

The NIPFP research provides evidence of this variation, showing that some categories experienced price increases while others recorded declines after the GST restructuring.

Inflation and GST Are Different Issues

It is also important to distinguish GST policy from overall inflation.

GST is a tax on the supply of goods and services, while inflation measures changes in the prices of goods and services over time.

A GST reduction can lower the tax component of a product's price, but broader inflationary forces can subsequently influence the price consumers actually pay.

Consequently, the two effects can operate simultaneously.

A product may receive a GST reduction while its underlying production or distribution costs rise, reducing the visible benefit to consumers.

Congress Raises Broader Growth Concerns

Ramesh also linked the GST debate to wider concerns about India's economic performance.

He said headline quarterly GDP numbers could provide a temporary positive impression while masking what he described as weaknesses in consumption, private investment and real wages.

These comments form part of Congress's broader political criticism of the government's economic record.

Whether the GST reductions have materially strengthened overall economic growth requires assessment using a broader range of indicators, including consumption expenditure, investment, inflation, tax collections, sectoral sales and real household incomes.

Government Has Highlighted Stable Essential-Commodity Prices

The government's position has differed from the latest Congress criticism.

In a March 2026 response to a Rajya Sabha question, the Finance Ministry said that between October 2025 and January 2026, CPI inflation had moderated to 1.1%, compared with 1.7% during July-September 2025.

The government also said that most essential commodities monitored by the Department of Consumer Affairs had remained stable or shown a declining trend during that period.

This provides a different perspective from the more recent Congress argument that inflation has eroded the benefits of GST reductions.

Why the GST Debate Matters for Consumers

The debate is ultimately about whether lower GST rates translate into lower prices and stronger purchasing power.

For consumers, the impact depends on several stages:

GST reduction → lower tax component → possible reduction in retail price → changes in demand

But other factors can intervene:

Higher input costs → higher production costs → higher retail prices

This is why the effect of a tax reduction can vary substantially across industries.

What Consumers Should Watch

Consumers looking to understand whether GST reductions are benefiting them should focus on actual retail prices rather than tax rates alone.

Important indicators include:

• Pre-GST and post-GST prices

• Changes in raw-material costs

• Retail and wholesale inflation

• Product-level GST rates

• Manufacturer and retailer pricing

• Household income growth

• Consumer demand

• Sector-specific sales trends

Comparing prices over time can provide a clearer picture of whether a GST reduction has translated into an actual saving.

The Larger Economic Question

The GST debate also highlights a broader issue in economic policy: tax reductions do not operate in isolation.

For a GST cut to produce a sustained improvement in purchasing power, the reduction needs to be transmitted through the supply chain while other cost pressures remain manageable.

If commodity prices rise significantly, part of the initial tax benefit can be offset.

The available evidence suggests that this process has differed by product category rather than producing one uniform outcome across the economy.

What Happens Next?

The impact of the GST rationalisation will continue to depend on inflation, input costs, consumer demand and pricing behaviour across different industries.

The Congress is likely to continue using consumer prices, consumption and household purchasing power as part of its criticism of the government's economic policies.

Meanwhile, policymakers will continue to assess whether GST changes are being adequately transmitted to consumers and whether tax rationalisation is supporting broader economic activity.

Bottom Line

The Congress has claimed that rising prices are eroding the benefits of the GST rate reductions introduced in September 2025. Jairam Ramesh argued that the impact on consumption has been mixed and that prices of some consumer goods have moved back towards pre-GST-cut levels.

Independent NIPFP research indicates that the impact of GST restructuring has varied by category: several food, household and personal-care products saw higher CPI readings, while some consumer durables recorded lower prices.

The debate therefore goes beyond whether GST rates were reduced. The key question for consumers is how much of those reductions ultimately reaches retail prices and how long the benefit lasts amid changing inflation, input costs and demand conditions.
