Composite installation contracts and TDS: material purchases excluded, service payments tested separately, with disallowance confined to deductible default only.

Composite installation contract payments were examined for TDS purposes under section 194C and consequent disallowance under section 40(a)(ia). The material component of the contract was treated as outside TDS deduction in the assessee's hands, while the labour or service component had to be tested separately against the actual deductions made and the statutory monetary limits. Payments below the prescribed threshold were not subject to deduction, and only the balance amount on which tax was deductible but not deducted could be considered for disallowance. The disallowance was also stated to be restricted to 30% where applicable, limiting the TDS default adjustment to the deductible service portion only.

Issues: Whether the disallowance under section 40(a)(ia) of the Income-tax Act, 1961 for alleged failure to deduct tax at source under section 194C was justified in respect of the installation contract payments and, if not, to what extent it could be sustained.

Analysis: The assessee had produced books of account and supporting details showing that the expenditure comprised both material purchases for installation and service or labour charges. The material component was held not to attract tax deduction at source in the assessee's hands, while the service component had to be examined separately with reference to actual deductions made and the statutory thresholds under section 194C(5). On the facts found, tax had been deducted on a substantial part of the labour payments, and certain small payments were outside the deduction requirement because they did not cross the monetary limits prescribed by law. Following the view applied in the order, only the balance amount on which tax was deductible but not deducted could be subjected to disallowance under section 40(a)(ia), and even that disallowance was to be restricted to 30%.

Conclusion: The disallowance was not sustainable in full and was limited to Rs. 17,01,816, with the assessee succeeding to that extent.

Final Conclusion: The assessment addition made on account of TDS default was substantially reduced, and the appeal succeeded only in part.

Ratio Decidendi: In a composite installation contract, material purchases not requiring deduction at source cannot be brought within section 40(a)(ia), and for the remaining deductible service component the disallowance must be confined to the amount lawfully subject to TDS default, with the statutory cap applied where applicable.
