Tamil Nadu reportedly asked for GST revenue to be divided 70:30 in favour of states at the 57th GST Council meeting in New Delhi on 8 October 2026. The proposal, attributed to Finance, Planning and Development Minister N Marie Wilson, is distinct from the states’ 41 per cent share of central taxes recommended by the 16th Finance Commission.
What does the 70:30 demand mean?
According to DT Next’s 8 October 2026 report, Tamil Nadu sought a 70:30 division of GST revenues between states and the Union, with the larger share going to states. The report attributes the request to Minister N Marie Wilson, who reportedly argued that states bear more than 60 per cent of public expenditure and need additional revenue to address fiscal imbalances.

That expenditure figure is the minister’s reported rationale, not an independently verified statistic here. The report does not establish the precise calculation base for the proposed split. No primary Tamil Nadu submission, Council minutes or official decision confirming the demand’s detailed terms or outcome was available.

Is this the same as the states’ 41 per cent share of central taxes?
No. The 70:30 figure concerns a reported proposal about GST revenue-sharing. The 41 per cent figure is the states’ vertical share of the divisible pool of central taxes under the 16th Finance Commission recommendation, which the Union accepted in 2026. These are separate mechanisms with different revenue bases; the 41 per cent figure is not the existing GST split. The Finance Commission’s materials describe the central-tax devolution framework.

Why a simple 50:50 GST description can mislead
GST includes different tax components and allocation rules, rather than one universal division that applies identically to every transaction. The Central Board of Indirect Taxes and Customs explains that SGST is a state tax. For inter-state supplies, IGST is levied and collected by the Union, then apportioned between the Union and states under parliamentary law based on GST Council recommendations. The reported demand’s exact application to these components has not been confirmed in a primary Council document.
That distinction matters for readers comparing percentages: a proposed 70:30 share cannot be evaluated without knowing which revenues it would cover and how the split would be implemented. The available report does not specify those details. CBIC’s GST explainer outlines the tax components and IGST apportionment.
What is the fiscal context for Tamil Nadu?
SGST is a major source of state revenue
PRS Legislative Research’s Tamil Nadu Budget Analysis 2026–27 identifies SGST as the state’s largest own-tax revenue source. It estimates SGST receipts of ₹85,200 crore for 2026–27, 7 per cent above the revised estimate for 2025–26. This is a budget estimate, not a final revenue outturn.

Tax devolution concerns extend beyond this GST request
The 16th Finance Commission report records broader state concerns that cesses and surcharges are excluded from the divisible pool of central taxes. It notes proposals to include those levies, cap their share of gross tax revenue, or increase states’ share if they remain outside the pool. That is wider fiscal-federalism context; it does not establish that these proposals formed part of Tamil Nadu’s specific GST Council demand. The Commission’s report discusses these issues.
GST compensation is a separate issue
During a Lok Sabha debate on 3 December 2025, an MP claimed that the end of GST compensation on 30 June 2022 caused Tamil Nadu an annual revenue shortfall of ₹20,000 crore. This is the speaker’s parliamentary claim, not an independently verified state estimate, and it should not be treated as a confirmed calculation of the state’s loss. The Lok Sabha debate record is the source for that statement.

DT Next also reported that Wilson sought separate special packages for exporting states. That request is distinct from the reported GST revenue-sharing proposal and from Finance Commission devolution; the report does not provide a confirmed decision on either request.
