GST 2.0 Spells Concerns Of Revenue Loss, But Risk Of Fiscal Slippage Low
The potential revenue loss could be offset by chances of higher dividends from PSUs, higher dividends from the Reserve Bank of India, and hike in excise duty on diesel and petrol, say economists.

The government's next generation GST reforms could boost disposable income, power consumption, provide a leg up to private capex and may nullify the impact of US tariffs on GDP — all while permitting the government to stick to fiscal deficit target for fiscal year 2025-26, according to experts.
The gains to Indian consumers might just be the government's loss in terms of tax collections, which are already seen to be on a weak footing. However, the potential revenue loss could be offset by chances of higher dividends from PSUs, higher dividends from the Reserve Bank of India, and hike in excise duty on diesel and petrol, as per Gaura Sengupta, chief economist at IDFC First bank.
The gross revenue loss from the tax cuts is about Rs 93,000 crore in a consumption base of FY24, according to estimates by Pranjul Bhandari, chief economist at HSBC. Revenues folded from the compensation cess to the 40% tax bracket can fund Rs 45,000 crore of the loss, leaving a net loss of Rs 48,000 crore, which is 0.16% of GDP.
Scaling this to the FY26 base implies a net revenue loss of Rs 57,000 crore (0.16% of GDP) over a year. Since only half the fiscal year is left, the implication for FY26 would be around 0.1% of GDP, according to estimates by Bhandari.
"Our calculations suggest the net impact on the central government’s fiscal deficit, assuming no capex adjustments would be close to 20 basis points," said Venugopal Garre, managing director and head of research at Bernstein, assuming that about 65% of the total benefit to consumers is recycled into consumption. If capex is reduced by 5%, the impact moderates to about five basis points, he added.
As of now, the Centre's loss in the second half of FY26 appears to be small, and may be absorbed by the higher dividend from RBI, said Aditi Nayar, chief economist at ICRA. However, if expenditure rises, for instance towards a potential package for exporters, the size of the same would affect the overall fiscal deficit, she added.
GDP Growth: Nullifying The Tariff Impact
At the first impression, the GST rate changes look favourable especially since there is across the board decline in daily use items including services, as well as critical items like cement, which should be huge positive for the infrastructure sector, said Garima Kapoor, economist at Elara Capital. The efforts to further ease the compliance burden on tax filers is positive and should aid ease of doing business, she added.
"We expect GST-related demand boost to add 100 to 120 bps to the GDP growth over next four-to-six quarters, thereby nullifying the negative impact of higher tariffs on exports to US," Kapoor estimated.
Over a year, led by stronger consumption, GDP growth can rise by 0.2 percentage points, according to estimates by Bhandari. It is also important to put the GST cuts in a broader context, she added.
The GST rate rationalisation, along with the income tax rebates announced in the Union Budget, looser monetary policy and lower inflation, appear to be paving the way for consumption to drive GDP growth.
"If we add on the benefits from the income tax cut earlier this year, and a lower debt servicing burden due to repo rate cuts (0.17% of GDP), the overall boost to consumption can be 0.6% of GDP," Bhandari estimated, adding that the net boost could be lower since a part of this could be saved instead of spent.
Together with lower inflation, a good monsoon, and rate cuts, the move should lift utilisation levels and revive the private capex cycle, stated a research note by Dolat Capital.
The tax cuts can also lower headline CPI by about 1 percentage point if producers pass on all benefits to consumers, according to estimates by Bhandari. If the pass-through is only partial, the inflation fall could be closer to 0.5 percentage point she added.
