Product taxes

Also called: Net product taxes · Topic: National Income Accounting: GDP, GVA and Welfare · NCERT: Class 12, Ch 2 "National Income Accounting"

Meaning

Product taxes are indirect taxes charged per unit of a good or service that is produced or traded, such as GST, excise duties and customs duties. When product subsidies are subtracted from them, the result is net product taxes, and this is the amount added to GVA to get GDP.

• Formula: GDP at market prices = GVA at basic prices + product taxes − product subsidies
• MoSPI's official form: "GDP (Production/Income Approach) = GVA at Basic Price + Net Taxes on Products" [4]

This matters because net product taxes are the whole gap between GDP and GVA. GDP growth can therefore change because of taxes and subsidies even when actual production stays the same.

Explanation

How product taxes work

• An indirect tax is a tax on goods, services or production, not on income. It makes the price the buyer pays higher than what the producer receives.
• A product tax is linked to each unit. Sell more units and you pay more tax.
• Examples: GST, excise duties, customs duties.

• NCERT still lists service tax as a product tax. Service tax was merged into GST from July 2017.

• A product subsidy works in the opposite direction. It is a government payment per unit that lowers the price the buyer pays.

• MoSPI's examples: food, petroleum and fertiliser subsidies [5].

• Net product taxes = product taxes − product subsidies.

Where product taxes sit in the valuation chain

Output can be valued at three prices. The difference between them is which taxes are included.

• Factor cost counts only payments to the factors of production (wages, rent, interest, profit). No taxes are included.
• Basic prices = factor cost + net production taxes. Product taxes are still left out.
• Market prices = basic prices + net product taxes. This is what buyers actually pay.

The chain:

• GVA at factor cost + net production taxes = GVA at basic prices
• GVA at basic prices + net product taxes = GDP at market prices
• GDP at factor cost = GDP at market prices − net product taxes − net production taxes

Worked example (₹ crore, one small economy):

Step	Item	Value
1	GVA at factor cost	100
2	+ Net production taxes (land revenue, stamp duty 6 − production subsidy 1)	+5
3	= GVA at basic prices	105
4	+ Net product taxes (GST, excise 18 − fertiliser subsidy 3)	+15
5	= GDP at market prices	120

• 120 − 15 = 105. This is GVA at basic prices, not factor cost.
• To reach factor cost you must also subtract the 5 of net production taxes: 120 − 15 − 5 = 100.

What makes net product taxes rise or fall

• The wedge widens (GDP grows faster than GVA) when:
• GST and other tax collections are strong, or

• subsidies are cut.

• The wedge narrows (GDP grows slower than GVA) when:

• subsidies rise, for example food or fertiliser subsidies in a shock year.

• Everyday examples:

• Petrol is heavily taxed, so its market price is well above its factor cost.
• Cooking gas (LPG) is subsidised, so its market price is below its factor cost.

In India

• Who measures it: the NSO (National Statistical Office) under MoSPI. The old CSO is now part of the NSO.
• How MoSPI builds it (2024-25 estimates):
• Product taxes at current prices come from CGA (Controller General of Accounts) and CAG data. They cover both GST and non-GST revenue [4].
• The Centre's product subsidies are built from food, urea, petroleum and nutrient-based subsidies [4].

• At constant prices, product taxes are moved forward using the volume growth of the taxed goods and services [4].

• January 2015 revision: the headline became GDP at market prices, and sector data moved to GVA at basic prices. From then on, net product taxes became the link between the two.

• Current series (base 2022-23, released 27 February 2026): it keeps the same rule, GDP = GVA at basic prices + net taxes on products [2][3].

Item (current prices)	2024-25 (FRE)	2025-26 (SAE)
GVA at basic prices	₹2,88,54,467 cr	₹3,13,60,846 cr
Net taxes on products	₹29,52,841 cr	₹31,86,311 cr
GDP	₹3,18,07,309 cr	₹3,45,47,157 cr

(FRE = First Revised Estimates; SAE = Second Advance Estimates) [3]

• Share in GDP: net product taxes were about 9.2% of GDP in 2025-26 at current prices [3].
• Old series (2011-12 base), 2024-25: at constant 2011-12 prices, net taxes on products were ₹16,09,509 crore, and GDP was ₹1,87,96,955 crore [4].
• NCERT error: Table 2.5 labels this row "net production taxes". It should be net product taxes, because GVA at basic prices already includes production taxes.

Don't confuse with

• Production taxes: these are paid just for producing at all and do not change with the amount produced. Examples are land revenue and stamp and registration fees [5]. They are added to go from factor cost to basic prices. Product taxes are added to go from basic prices to market prices.
• Net indirect taxes: this is the total of net product taxes and net production taxes. Subtracting it from GDP at market prices gives GDP at factor cost. Subtracting only net product taxes gives GVA at basic prices.
• Direct taxes (income tax, corporation tax): these are taxes on income, not on goods. They are not part of the GDP–GVA wedge.
• Product subsidies vs production subsidies: food, fertiliser and petroleum subsidies are product subsidies [5]. They are subtracted from product taxes, not from production taxes.

Prelims Hooks

• GST, excise and customs are product taxes. Land revenue and stamp and registration fees are production taxes [5].
• GDP at market prices = GVA at basic prices + net product taxes. This is MoSPI's official form [4].
• Trap: GDP at market prices − net product taxes = GVA at basic prices, not GDP at factor cost.
• Food, fertiliser and petroleum subsidies are product subsidies. They reduce net product taxes [5].
• 2023-24 (old series, real terms): net product taxes grew 16.5%, GVA grew 8.6% and GDP grew 9.2% [4].
• The 2022-23 base series (released 27 February 2026) keeps the rule GDP = GVA + net taxes on products and still follows SNA 2008 [2][3].

Mains Points

• GVA is the better measure of real production:
• GDP growth can rise only because taxes rise or subsidies fall.
• In 2023-24 (old series), real GDP grew 9.2% but real GVA grew only 8.6%, because net product taxes jumped 16.5% [4].

• So use GVA to judge what sectors actually produced. Use GDP for comparing with other countries and for demand-side analysis.

• Fiscal policy shows up in the headline GDP number:

• More food or fertiliser subsidies → lower net product taxes → GDP grows slower than GVA.
• Stronger GST collections or subsidy cuts → GDP grows faster than GVA.

• In 2025-26 (new series, nominal), net product taxes grew 7.9% against GVA's 8.7%, so GDP grew 8.6% and the wedge narrowed slightly [3].

• Statistical quality and comparability:

• In the 2022-23 series, GST data is used to cross-check the annual accounts and to build quarterly estimates [2].
• Presenting GDP and GVA at market and basic prices under SNA 2008, and following the IMF's SDDS, keeps India's data comparable with other countries [2].
• The planned move to SNA 2025 will be the next test [2].
