India Fiscal Deficit: Excise Duty Cuts Lift FY26 Gap

What changed and why it matters

India’s fiscal arithmetic has come under pressure after the Centre cut excise duty on petrol and diesel by ₹10 per litre each in March to cushion consumers from elevated global crude prices linked to the war in West Asia. The decision has been associated with an estimated revenue loss of nearly ₹0.14 trillion per month. With receipts weakening and spending rising, multiple snapshots of government accounts across FY26 and early FY27 show a wider fiscal deficit and slower tax buoyancy.

The excise duty cut and the expected revenue hit

The excise duty reduction was announced on March 27. When the duty cut was rolled out, officials projected a net revenue shortfall of ₹0.055 trillion during the initial two weeks, after considering windfall gains. Over a full month, the implied revenue impact was estimated at nearly ₹0.14 trillion.

This matters because excise duties on petroleum products are a large and relatively stable source of central indirect tax revenues. A sharp step-down in rates can quickly show up in monthly cash flows, especially when other revenue lines do not compensate.

April 2026: deficit spikes as receipts fall and spending rises

In April 2026, India’s fiscal deficit jumped to ₹3.62 trillion, almost twice as high as last year. This level was already over 21% of the full-year target. A “big chunk” of the widening was linked in the data narrative to the recent excise duty cuts on petrol and diesel.

Receipts (excluding borrowings) fell sharply. Government receipts dropped by nearly 24% year-on-year to ₹2.13 trillion, with non-tax revenue taking a significant hit. On the other side of the ledger, expenditure rose by about 24% to ₹5.75 trillion, driven by higher food and urea subsidies and increased capital spending.

April-May FY27: muted tax growth and a drag from excise

ICRA Chief Economist Aditi Nayar said fiscal expansion during April-May was driven by an 18% surge in total expenditure and a 1%-2% contraction in net tax receipts and non-tax revenues. The same period also saw a muted 1.8% year-on-year rise in the government’s gross tax revenues, led by a sharp 20% contraction in excise duty collections after the reduction in duties on petrol and diesel.

While the excise rate cut was substantial, the cash-flow outcome can vary month to month depending on timing effects and accounting, including refunds and transfers.

A counter-intuitive April excise print in CGA data

Despite a ₹10 per litre reduction in taxes on petrol and diesel, the article data notes that central excise revenues in April surged to ₹0.00447 trillion, up from a deficit of ₹0.00039 trillion in the same month last year, citing CGA-related information.

This single-month improvement sits alongside the broader point that excise collections contracted sharply over April-May FY27. The mixed signals highlight why analysts often focus on broader periods and trend lines, rather than one-off monthly prints.

Subsidies add to the near-term strain

Dev Pant, Economist at Ratings & Research, said spending on food and fertiliser subsidies rose by 50.7%, contributing to a year-on-year increase of 94.4% in the fiscal deficit for the month. He also cautioned that one month’s data does not define the full-year trajectory, but flagged expected pressure on public finances from the excise duty reduction and anticipated higher petroleum and fertiliser subsidies.

GST rate cuts and the indirect tax backdrop

The article also points to another source of indirect tax weakness in FY26: GST rate cuts that came into effect on September 22. In November (reflecting sales in October), GST collections were ₹0.17 trillion versus ₹0.169 trillion in November 2024. Including compensation cess, collections in November were down 4% at ₹0.175 trillion.

Other indirect tax lines were also soft in the reported period. Customs collections were 7% lower in April-November, while money from excise duties was 9% higher in April-November. Net tax revenue was down 14% in November and down 3% for April-November.

FY26 progress checks: April-September and April-November

For the first half of FY26 (April-September), government sources cited a fiscal deficit of ₹5.73 trillion versus ₹4.75 trillion in the same period last year, with the deficit at 36.5% of the full-year target. Over the same period, capital expenditure rose 40% year-on-year to ₹5.8 trillion.

Another CGA-based summary for April-September stated total expenditure at ₹23.03 trillion (43.5% of the full-year target), net tax collections at ₹12.30 trillion (43.3% of the budget estimate) and non-tax revenue at ₹4.66 trillion (nearly 80% of the annual target), led by higher receipts from PSUs and dividends.

For April-November of FY26, the fiscal deficit was reported at ₹9.76 trillion, or 63% of the FY26 budget estimate of ₹15.48 trillion. Aditi Nayar noted that capex rose 28% year-on-year in this period, while net tax revenues contracted 3.4% and non-tax revenues expanded 20.8%.

Key numbers at a glance

Market impact and what investors track next

A wider fiscal deficit can influence expectations around government borrowing and the pace of spending in the rest of the year. In the periods cited, the fiscal gap widened alongside higher capital outlays and subsidy spending, while tax revenues showed muted growth or contraction in net terms.

Investors typically monitor whether higher capex is sustained, how quickly subsidy bills normalise, and whether non-tax revenues continue to support the fiscal math. They also watch indirect tax trends after GST rate changes and petroleum tax adjustments, because these can materially shift monthly receipts.

Why the data is being read cautiously

Economists quoted in the article emphasised two points. First, monthly prints can be volatile, and one month’s data may not reflect the full-year pattern. Second, the combination of excise duty cuts and potentially higher petroleum and fertiliser subsidies can keep pressure on receipts and revenue expenditure even if direct taxes improve.

ICRA’s Aditi Nayar said the Centre’s tax performance showed a split: better direct taxes but subdued indirect taxes post GST rationalisation, alongside factors such as IGST settlement affecting gross tax revenue in 8M FY2026.

Conclusion

The fiscal deficit widened in multiple FY26 checkpoints and in April 2026, reflecting weaker receipts and higher spending, with excise duty cuts on petrol and diesel a key driver of the near-term revenue hit. The next signals to track are subsequent CGA monthly updates on excise and GST collections, the pace of subsidy spending, and how capex is sequenced through the remainder of the fiscal year.
