Mutuality doctrine does not exempt trading profits where a co-operative society sells its own produce to members at market rates.

The doctrine of mutuality applies only where contributors to a common fund and participators in that fund are identical, and the association merely returns members' own contributions. A co-operative society that owned tea land, grew and manufactured tea, sold it at market rates to members, and treated the surplus as trading profit did not satisfy that test. Member purchases did not eliminate the presence of real trading receipts, and member advances were treated as loans rather than mutual contributions. The claimed exemption therefore failed, and the society remained liable to Assam agricultural income-tax on profits from the tea sales.

Issues: Whether a co-operative society which cultivated tea on its own land, manufactured it, and sold it to its members at market rates was exempt from Assam agricultural income-tax on the footing that the receipts were not profits but merely mutual contributions returned in another form.

Analysis: The principle of mutuality applied only where the contributors to a common fund and the participators in that fund were identical, and where the association was merely an instrument for collecting and returning the members' own contributions. That principle was confined to true mutual insurance or analogous arrangements. Here, the society owned the estate, produced tea by its own operations, sold the tea at a genuine price, and applied the surplus as trading profits under its rules. The fact that the purchasers were members did not destroy the existence of profits, and the advances made by members were treated as loans, not as a common fund producing mutual returns. The arrangement therefore did not fall within the exemption recognised in mutuality cases.

Conclusion: The society was not exempt from liability to Assam agricultural income-tax in respect of profits from the sale of tea to its members, and the contention based on mutuality failed.

Ratio Decidendi: The doctrine of mutuality exempts only transactions where there is complete identity between contributors and participators in a common fund, and it does not extend to a society that carries on a real trading business, earns profits from the sale of its own produce, and sells that produce to its members.
