1. At a Glance

MoSPI is revising the base year of National Accounts from 2011-12 to FY 2022-23, with the new GDP series scheduled for release on 27 February 2026 [S1][S2][S4].
The exercise is steered by the Advisory Committee on National Account Statistics (ACNAS) chaired by Prof. B.N. Goldar, which set up five Sub-Committees (2-year term) on specific subject areas [S1][S2].
The Sub-Committee on Incorporation of New Data Sources, Rates and Ratios (headed by Shri Manish Sinha, CEO, GSTN) submitted its report on 24 February 2026, recommending greater use of GST, HCES 2022-23 and MCA NBFC data in GVA/PFCE compilation [S1].
UPSC relevance: GDP methodology revision is a recurring GS-III (Economy/Statistics) theme; rebasing changes sectoral weights, state shares and headline growth.

2. Why in the News

24 Feb 2026: MoSPI released the Report of the Sub-Committee on Incorporation of New Data Sources, Rates and Ratios under ACNAS [S1].
Part of a sequenced release: Sub-Committee on Methodological Improvements report released 18 Feb 2026; Sub-Committee for Constant Price Estimates released 20 Feb 2026 [S2][S3].

3. Background & Evolution

National Accounts Statistics (NAS) are compiled by the National Statistical Office (NSO) under MoSPI; base years revised periodically to reflect structural changes [S1].
Past base years: 1948-49 → 1960-61 → 1970-71 → 1980-81 → 1993-94 → 1999-2000 → 2004-05 → 2011-12 → (proposed) 2022-23 [S1].
The current revision skips a normal ~5-year cycle (delayed due to COVID-era data anomalies); 2022-23 chosen as a structurally "normal" reference year [S1].
ACNAS under Prof. B.N. Goldar constituted to advise on methodology and data sources [S1][S2].

4. Core Static Facts

Parent ministry: Ministry of Statistics and Programme Implementation (MoSPI) [S1].
Apex advisory body: ACNAS — Advisory Committee on National Accounts Statistics; Chair: Prof. B.N. Goldar [S1].
Sub-Committee head: Shri Manish Sinha, CEO, Goods and Services Tax Network (GSTN) [S1].
Composition: Academia/researchers, Central & State Governments, RBI [S1].
Mandate: Review data sources of 2011-12 series; identify new administrative/survey sources for production-side and expenditure-side aggregates [S1].
New base year: FY 2022-23; new series release date: 27 Feb 2026 [S2][S4].
Number of Sub-Committees under ACNAS: Five (2-year term) [S2].

Key New Data Sources Recommended

GST data → regional allocation of GVA; estimation of private corporate GVA contribution to GSDP (replacing indicator-based method of 2011-12 series) [S1].
HCES 2022-23 (Household Consumption Expenditure Survey) → direct estimation of base-year PFCE (Private Final Consumption Expenditure) [S1].
MCA database (Ministry of Corporate Affairs) → actual financial data of Private NBFCs, replacing proxy-based loan-growth method on a sample of companies [S1].

5. Multi-Dimensional Analysis

Economic

More granular state-level GVA estimates via GST should reduce reliance on indicator-based apportionment, sharpening GSDP comparability [S1].
Direct use of HCES 2022-23 in PFCE benchmarking can recalibrate the consumption share of GDP (~55-60% of GDP) [S1].
Shift to MCA actuals for NBFCs improves measurement of the financial sector, where NBFCs are systemically important [S1].

Administrative / Governance

Reflects a structural pivot from survey-based to administrative-data-based national accounting, leveraging digital tax (GST) and corporate filings [S1].
Multi-stakeholder design (RBI, States, academia, GSTN) signals strengthening of cooperative statistical federalism [S1].

Scientific / Technological

Use of GSTN-driven granular taxpayer data exemplifies big-data integration into official statistics [S1].
Aligns Indian NAS practice closer to SNA 2008 prescriptions on administrative-data use (system-level methodological convergence) [S1].

Ethical / Statistical Credibility

Earlier 2011-12 series faced criticism over MCA-21 data quality and discontinuity vs old series; broader, verifiable sources aim to restore credibility [S1].
Need to ensure back-series consistency for time-series analysts and research users [S1].

8. Mains Relevance

GS-III — Indian Economy: mobilization of resources, growth, development; Statistical infrastructure**.
GS-II — Government policies; Statutory/regulatory bodies (cooperative federalism via States' inclusion in ACNAS).
Plausible question stems: 1. "Periodic revision of base year of National Accounts is essential for credible measurement of growth. Discuss the methodological shifts proposed for the 2022-23 base year series." (250 words) 2. "How can integration of administrative data sources (GST, MCA-21, HCES) improve the credibility of India's GDP estimates? Critically examine." (150 words) 3. "Discuss the role of ACNAS and Sub-Committees in modernising India's National Accounts Statistics." (150 words)

9. Related Topics to Study Next

GDP vs GVA vs GNI — basic concepts revisited in any rebasing question.
HCES 2022-23 & 2023-24 — directly feeds the new PFCE benchmark.
MCA-21 database — controversial input since 2011-12 series.
GSTN architecture — now a statistical data backbone.
Periodic Labour Force Survey (PLFS) — companion administrative-survey reform.
SNA 2008 (UN System of National Accounts) — international template Indian NAS follows.
NSO restructuring (merger of CSO + NSSO, 2019) — governance backdrop.
State Domestic Product / GSDP estimation — directly affected by new GST-based allocation.

10. Common Errors / Trap Areas

Confusing ACNAS with the older National Statistical Commission (NSC) — ACNAS is a technical advisory committee specifically for NAS, not the statutory NSC [S1].
Wrongly attributing GDP compilation to RBI or Ministry of Finance — it is MoSPI/NSO [S1].
Mixing up base year (2022-23) with release year (2026) in MCQs [S2].
Assuming all five Sub-Committee reports are the same — each covers a distinct domain (Data Sources, Methodological Improvements, Constant Price Estimates, etc.) [S2].
Forgetting that HCES is conducted by NSO under MoSPI, not NITI Aayog.
