GVA, net taxes and GDP

India publishes two headline growth rates every quarter. Reading one as the other is the most common error in this subject, and the difference turns out to be interesting rather than technical.

Value added, and why it has to be value added

Chapter 1 said only final goods count, or things would be counted twice. Gross Value Added is the machinery that enforces it.

For any producer:

value added = output − intermediate consumption

What you sold, less what you bought from others to make it. A bakery selling ₹100 of bread, having bought ₹30 of flour, has added ₹70 of value. Add that ₹70 across every producer and nothing is counted twice: the flour mill's contribution is counted once, in the mill's own value added.

GVA is therefore the production-side total, and it is where India's accounts start. The quarterly press note leads with sectoral GVA and reaches GDP afterwards.

The bridge

GVA is measured at basic prices — what the producer actually receives. GDP is measured at market prices — what the purchaser actually pays. Between the two sit taxes and subsidies on products.

GDP = GVA at basic prices + taxes on products − subsidies on products

The last two together are net taxes on products. GST on a sold item is in the price the buyer pays and not in what the producer keeps; a subsidy on fertiliser works the other way.

So GDP is larger than GVA, by the amount of net indirect tax sitting in final prices.

The identity, to the rupee

From the Q1 2026-27 press note, at current prices, in ₹ crore:

	Q1 2025-26	Q1 2026-27
GVA at basic prices	72,23,548	80,53,369
Net taxes on products	7,76,644	7,73,502
GDP at market prices	80,00,192	88,26,871

Add the first two rows:

80,53,369 + 7,73,502 = 88,26,871

Exactly. Not approximately — this is an accounting identity, so it holds to the rupee, and if your arithmetic misses it you have the wrong line rather than a rounding problem. The same addition works for the previous year: 72,23,548 + 7,76,644 = 80,00,192.

Now the growth rates, and the gap

Q1 2026-27, year on year	Nominal	Real
GVA growth	11.5%	8.2%
GDP growth	10.3%	7.8%

GVA grew faster than GDP on both measures. That is the reverse of the usual case and it is entirely explained by one line.

Look again at net taxes: ₹7,76,644 crore falling to ₹7,73,502 crore — down 0.4% while value added rose 11.5%.

Net taxes on products went backwards in nominal terms. Since GDP is GVA plus that line, a shrinking bridge drags GDP growth below GVA growth. The whole of the 1.2-point nominal gap and the 0.4-point real gap is there.

Which one describes the economy

This is the judgement the exercise asks for, and it has a defensible answer.

GVA is the better measure of production. It is what producers actually added, unaffected by what the government does to tax rates. If GST is cut tomorrow with no change in output, GVA is unmoved and GDP falls.

GDP is the better measure of the size of the economy at the prices people face, and it is the internationally comparable headline. It is what goes into debt-to-GDP, deficit-to-GDP and per-capita income.

So: a quarter where GVA grew 8.2% in real terms and GDP grew 7.8% is a quarter where production grew faster than the headline suggests, and the shortfall is a tax effect rather than a production one. Anyone describing that quarter as a slowdown relative to value added would be describing the tax line.

The reverse case is more common and worth recognising: when net taxes grow quickly — a GST rate rise, a fuel duty increase, subsidies being withdrawn — GDP growth runs above GVA growth and the economy looks better than production alone would say. Neither number is wrong. They answer different questions, and the gap between them is the answer to a third.

Where the sectors sit

GVA is also where the sectoral story lives, because it is the production-side total. At current prices, Q1 2026-27 against the year before:

Sector	Growth
Primary — agriculture, livestock, forestry, fishing, mining	9.0%
Secondary — manufacturing, utilities, construction	11.0%
Tertiary — trade, transport, finance, real estate, IT, public administration	12.6%

Within those, mining and quarrying grew 22.3% and construction 16.5%, while manufacturing grew 7.7%. The composite national figure conceals a wide spread, which is the same lesson the inflation subject reached about a basket of goods and this subject keeps reaching about a basket of industries.

The point

GVA is output less intermediate consumption, measured at the prices producers receive; GDP adds net taxes on products to reach the prices purchasers pay, and the identity holds to the rupee. In Q1 of 2026-27 nominal GVA grew 11.5% while nominal GDP grew 10.3%, entirely because net taxes on products fell 0.4%. GVA describes production and GDP describes the economy at market prices — so when they diverge, the gap is a statement about tax rather than about output.
