Mining Contract Tax-Change Clause After MMDR Amendment Act 2026: Buyer, Lessee and Lender Review
By Ravi Sisodia · Reviewed by CA Divyanshu Sengar · Updated 5 October 2026
2-minute summary
- A clause saying 'all taxes for seller's account' may be too crude where royalty, GST, mineral-right levies, land charges and future change-in-law are treated differently.
- The contract should state who initially pays, who can contest, what evidence is required for pass-through, and what happens when an amount is later refunded or held invalid.
- For financed projects, lender consent or DSCR tests may be triggered even before final legal resolution, so legal and treasury teams need the same event definition.
- Historic amounts should be carved out from future recurring charges where their treatment under the 2026 amendment differs.
Current position
Control and evidence map
| # | Control | What the file should show |
|---|---|---|
| 1 | Define tax buckets | List royalty/statutory contributions, indirect taxes, State levies and excluded items. |
| 2 | Set change-in-law test | Specify trigger date, materiality and proof. |
| 3 | Control disputes | Who conducts litigation and whether disputed amounts are paid, escrowed or withheld. |
| 4 | Build true-up mechanism | Refunds, credits and retrospective adjustments should flow to the economically entitled party. |
| 5 | Align financing | Check lender covenants, reserve accounts and information undertakings. |
Worked example
A long-term ore supply agreement permits pass-through of a State mineral levy. After the 2026 amendment, the buyer disputes the next invoice. The parties should not argue from the headline alone: the seller provides the charging instrument and demand, the buyer checks the contractual tax definition and effective-date clause, and any later refund is handled under the agreed true-up mechanism.
Common mistakes
- Using 'tax' without defining included and excluded charges.
- No rule for disputed amounts pending litigation.
- No refund/credit true-up after a levy changes.
- Contract wording inconsistent with lender model assumptions.
Frequently asked questions
Does the Act rewrite private contracts automatically?
No. Statutory liability and contractual allocation are separate questions.
Should royalty be grouped with every State tax?
Not without carefully defined drafting and legal analysis.
What evidence should support a pass-through invoice?
The legal instrument, demand/computation, proof of payment where relevant and the contract clause.
Why involve lenders?
A disputed levy can affect liquidity, reserves and covenant calculations even before the legal dispute ends.
