After every cyclone, Chennai hears two kinds of numbers: what the state asks the Centre for, and what the Centre releases. They rarely match, and they measure different things. How disaster relief money for Tamil Nadu is set, claimed and paid.
The numbers
Most of the disaster money Tamil Nadu receives from the Centre is not a special grant for a particular cyclone. It is the state’s routine annual share of its own State Disaster Response Fund (SDRF), fixed in advance by the Finance Commission and released in two equal instalments, sometimes early when a disaster strikes. Only for a disaster judged “severe” does extra money come from the National Disaster Response Fund (NDRF), after a central team visits and a committee chaired by the Union Home Minister approves it.
That is why the figures diverge. In 2021, after the November floods, Tamil Nadu’s third memorandum to the Centre sought ₹6,230.45 crore. The state’s SDRF allocation for the whole of 2021-22 was ₹1,088 crore, according to a Lok Sabha reply of 8 February 2022.
Two funds and a formula
For 2021-22 to 2025-26, the 15th Finance Commission recommended ₹1,60,153 crore for state disaster risk management funds, of which ₹1,28,122 crore (80 per cent) is for state response funds, and ₹54,770 crore for the NDRF, according to the Home Ministry’s disaster management portal. For general category states such as Tamil Nadu, the Centre pays 75 per cent of the SDRF and the state 25 per cent; for north-eastern and Himalayan states the split is 90:10. The NDRF is funded wholly by the Centre and tops up the SDRF only when it is not enough.
In 2021-22 Tamil Nadu’s ₹1,088 crore SDRF was made up of ₹816 crore from the Centre and ₹272 crore from the state. The central share was released in advance in two instalments of ₹408 crore each, the 2022 reply says. In December 2024, after Cyclone Fengal, the Centre released both instalments of the central share for that year, ₹944.80 crore, according to PIB. Dividing by 0.75 implies a total 2024-25 allocation of about ₹1,260 crore, roughly 16 per cent more than in 2021-22.
How a claim for extra help works
When damage exceeds what the SDRF can cover, the state submits a memorandum to the Centre. An Inter-Ministerial Central Team (IMCT) visits to assess damage. Its report goes to the High Level Committee chaired by the Home Minister, which approves any NDRF assistance. That approval is subject to a deduction: 50 per cent of the opening balance in the state’s SDRF for the year is adjusted against it, as successive releases note.
The November 2021 floods show how memoranda grow as assessments come in. The first sought ₹2,629.29 crore, the second, during the IMCT visit of 21 to 24 November, ₹4,625.80 crore, and the third, on 21 December 2021, ₹6,230.45 crore. Of the third, ₹1,510.83 crore was for immediate relief and temporary restoration and ₹4,719.62 crore for permanent restoration and mitigation. The reply in February 2022 said only that additional assistance was “being considered”, the Lok Sabha record shows.

The April 2025 approval of ₹522.34 crore for Tamil Nadu was part of ₹1,247.29 crore for three states for 2024 calamities, subject to the 50 per cent opening balance adjustment, according to PIB. The release does not say which Tamil Nadu event it covers. The Michaung and Chennai basin items both come from the Home Ministry’s 2023 year-end review.
It’s often said the money the Centre announces after a cyclone is a special package for that cyclone.
The record shows Often it is the state’s own routine SDRF instalments released early. The ₹944.80 crore after Fengal was “both the installments of central share” for the year, per PIB; extra NDRF money comes later, after the central team’s report.
Why the ask and the grant never match
A memorandum counts damage. The response funds are meant for immediate relief and temporary restoration, the same split the 2021 memorandum itself used. Permanent reconstruction and mitigation, which make up most of a large memorandum, are mostly funded through other routes, including separate mitigation funds and the state’s own budget. Comparing a memorandum with an NDRF release therefore compares two different measures, not a promise and a shortfall.
The national scale helps put Tamil Nadu’s figures in context. In 2024-25 the Centre released ₹20,264.40 crore to 28 states from SDRFs and ₹5,160.76 crore to 19 states from the NDRF, according to the April 2025 release. In February 2025 the High Level Committee approved ₹1,554.99 crore for five other states with the same opening balance condition, PIB reported.
Disasters the list leaves out
The response funds cover 12 notified disasters. Heat and sunstroke are not among them, but a state may spend up to 10 per cent of its annual SDRF allocation on disasters it notifies locally, subject to conditions, the Union government told the Lok Sabha in August 2025. That is the channel through which a state-declared heat disaster can draw on the fund.
What this means for you
- Relief payments to families after a flood or cyclone come mostly from the SDRF, under norms the state applies; ask your taluk office for the current rates.
- A large memorandum figure is an estimate of damage, not a sum the state expects to receive in full.
- Early release of SDRF instalments speeds cash for relief but does not add to the year’s total.
- Mitigation projects, such as the Chennai basin flood management project, are funded separately from relief and take years.
What to watch
