What Happened
- The Central Board of Direct Taxes (CBDT) initiated the NUDGE campaign — Non-Intrusive Usage of Data to Guide and Enable — starting December 2025, using data analytics to identify discrepancies in income tax returns.
- More than 50 lakh (5 million) taxpayers revised or updated their income tax returns in response to NUDGE notices sent via SMS and email.
- The voluntary corrective effort resulted in a reduction of approximately ₹2,000 crore in refund claims, classified as incorrectly claimed or potentially fraudulent.
- Over a broader two-year horizon, the NUDGE campaign led to 1.11 crore updated or revised ITRs, generating additional tax payments of ₹6,976.50 crore.
- The campaign contributed to slower refund processing — average turnaround time increased to 35 days (from 24–25 days in prior years), with about 27 lakh cases crossing the 90-day mark in FY2025-26.

CBDT and India's Direct Tax Administration
The Central Board of Direct Taxes (CBDT) is the apex body for direct tax administration in India, functioning under the Department of Revenue, Ministry of Finance. It administers the Income Tax Act, 1961, and is responsible for tax policy formulation, enforcement, and taxpayer services.
- CBDT constituted under the Central Board of Revenue Act, 1963; operates as a part of the Ministry of Finance.
- Administers: Income Tax Act 1961, Wealth Tax Act (now abolished), Black Money Act 2015, Benami Transactions Act.
- Tax year / Assessment Year: India uses a financial year (April–March) as the tax year; returns for FY2024-25 are filed in AY2025-26.
- India's direct tax-to-GDP ratio is approximately 6–7% — lower than global peers, reflecting a narrow tax base.
- Total income tax returns filed for AY2025-26: 8.80 crore (880 million) — the highest ever.
Connection to this news: The NUDGE campaign is CBDT's data-driven compliance enforcement tool — a behavioural governance approach to widening the effective tax base without adversarial litigation.
Behavioural Governance and Nudge Theory in Tax Compliance
Nudge theory (Thaler & Sunstein, 2008) proposes that indirect suggestions and positive reinforcement can influence behaviour more effectively than mandates or penalties. Applied to taxation, nudge mechanisms use data analytics to identify discrepancies and alert taxpayers, encouraging voluntary compliance before triggering formal enforcement action.
- India's NUDGE campaign uses Annual Information Statement (AIS) and Form 26AS data — which capture income from banks, property registrations, stock market transactions, and foreign remittances — to flag under-reported income or over-claimed deductions.
- AIS (Annual Information Statement) was launched in 2021 as an enhanced version of Form 26AS, providing taxpayers a comprehensive view of all their financial transactions reported to tax authorities by third parties.
- Non-intrusive compliance approach: taxpayers receive alerts to self-correct rather than facing immediate scrutiny or penalty.
- The updated ITR (ITR-U) mechanism — introduced in the Union Budget 2022 — allows taxpayers to file updated returns within 2 years of the assessment year, paying additional tax plus a surcharge.
- Compliance nudges reduce litigation costs for both taxpayers and the government.
Connection to this news: The NUDGE campaign's 50 lakh revised returns and ₹2,000 crore refund reduction demonstrate the revenue impact of behavioural governance — combining data analytics with voluntary compliance mechanisms rather than coercive enforcement.
Updated ITR (ITR-U) — Mechanism and Significance
The Income Tax Department introduced the updated return (ITR-U) in the Union Budget 2022-23 under Section 139(8A) of the Income Tax Act. It allows taxpayers who missed filing or under-reported income to correct their returns within 2 years of the relevant assessment year by paying additional tax.
- Introduced: Union Budget 2022-23 under Section 139(8A) of the Income Tax Act, 1961.
- Time limit: 2 years from the end of the relevant assessment year.
- Additional tax surcharge: 25% of aggregate tax + interest if filed within 12 months; 50% if filed between 12–24 months.
- Cannot be filed if the updated return would result in a refund or reduce existing tax liability.
- ITR-U was designed to mop up undisclosed income without triggering tax evasion proceedings — a softer compliance route.
Connection to this news: ITR-U is the specific vehicle through which many of the 50 lakh taxpayers corrected their returns under the NUDGE campaign — the CBDT's nudge mechanism and the ITR-U procedural route work together as a compliance ecosystem.
