The Mumbai Bench of the Income Tax Appellate Tribunal has given relief to a company named Nina Concrete Systems Pvt Ltd that faced tax additions due to a mismatch between its income records and Form 26AS. The company is engaged in the business of waterproofing, a critical material segment for the construction and architecture sector where specification compliance and project cash flow are closely tied to contract billing cycles. For Architecture, Engineering, and Construction firms that subcontract waterproofing works, the case highlights how income reconciliation issues can arise from project-linked receipts and Tax Deducted at Source entries reported by clients in Form 26AS.
In Assessment Year 2017-18 the assessee filed its return of income on 31 October 2017, declaring a loss of 2.06 crore rupees. Whereas in Assessment Year 2018-19 the assessee filed its return of income on 29 October 2018, declaring NIL income. The Income Tax Department found out that the income appearing in Form 26AS is different from the income shown in the companyโs profit and loss account. As a result, the Assessing Officer added 3.18 crore rupees for Assessment Year 2017-18 and 1.34 crore rupees for Assessment Year 2018-19 to the companyโs taxable income. In construction contracts, such mismatches often occur due to timing differences between invoice booking, certification of work, retention release, and TDS credit reflected in Form 26AS, which is auto-populated from client filings.
Form 26AS Reconciliation and Section 14A Disallowance
The company explained that it had a sister concern, Nina Waterproofing Systems Pvt Ltd, which operated in the same business. The Mumbai Bench of the Income Tax Appellate Tribunal granted partial relief to Nina Concrete Systems, ordering a fresh review of the Form 26AS mismatch and deleting a 40.16 lakh rupees disallowance made under Section 14A of the Income Tax Act. Section 14A relates to expenditure incurred in relation to income not includible in total income, and its deletion removes an additional tax burden on the firm. For material suppliers and specialist contractors in the building sector, accurate mapping of Taxpayer Information and TDS credits is essential, as project owners, developers, and main contractors deduct tax at source on running account bills and final bills.
The order directs the Assessing Officer to carry out a fresh review of the Form 26AS mismatch for both Assessment Years. This means the company will get an opportunity to reconcile entries, explain variances arising from inter-company transactions, and submit supporting documents such as reconciliation statements, ledger extracts, and client certificates. In the waterproofing and specialty construction chemicals industry, where firms often operate through multiple entities for manufacturing, application, and services, such reconciliations are common during assessments. The ruling underscores the importance of maintaining clear documentation between related entities to avoid additions due to automated data matching.
Nina Concrete Systems operates in waterproofing solutions used across residential, commercial, institutional, and infrastructure projects. The sector is integral to building envelope performance, basement protection, podium decks, and wet-area detailing, directly impacting project longevity and defect liability. Tax disputes that tie up working capital can affect a specialist contractorโs ability to procure materials, deploy trained applicators, and meet project timelines. Relief in such cases helps maintain liquidity for ongoing site execution and research and development in construction chemicals. The Income Tax Appellate Tribunalโs decision to delete the Section 14A disallowance also reduces litigation risk for similar firms where exempt income may not be present but the disallowance was invoked.
For architects, consultants, and developers who empanel waterproofing agencies, the case is a reminder to ensure that contract terms, billing schedules, and TDS certificates align with the vendorโs books to prevent downstream compliance disputes. Regular reconciliation of Form 26AS with books of accounts is a standard practice for firms in the construction value chain due to the volume of TDS entries from multiple projects and clients. The ITATโs direction for a fresh review allows tax authorities to examine the actual nature of transactions rather than rely solely on system-generated mismatches. While the matter pertains to tax administration, its resolution impacts the financial health of a company delivering critical building protection systems. As infrastructure and real estate projects scale up across India, clarity on tax treatment for specialist contractors supports smoother execution and vendor stability. The order was reported on 2 June 2026 and is relevant to construction material companies navigating income recognition and TDS credit issues.
