The ITAT upheld rejection of the assessee's books of account under section 145(3) because verifiable labour records, third-party confirmations, project-wise details and reconciliations were not produced, and major expenses rested on self-made vouchers with no credible support. Once the accounts were rejected, profit had to be estimated on a fair and reasonable basis, but the Tribunal found the Assessing Officer's 8% rate excessive because it relied on non-comparable listed companies and a section 44AD benchmark that could not be mechanically applied beyond the prescribed turnover limit. Considering the nature of the sub-contract business, remote working conditions and defects in the records, profit was estimated at 5% of turnover.
