Appeal partly allowed with issues remitted back for verification. Disallowance under Section 40(a)(ia) upheld.

The appeal was partly allowed with certain issues remitted back to the AO for further verification, while other grounds were dismissed or upheld as per the findings of the Tribunal. The disallowance under Section 40(a)(ia) of the IT Act was upheld due to non-deduction of TDS on earthwork expenses. Additionally, additions related to sales tax payment, staff salaries, labor charges, creditors for expenses, and cash payments exceeding the limit were confirmed. The alternative ground for income estimation was dismissed, affirming the AO's assessment based on audited books of accounts.

Issue-wise Detailed Analysis:

1. General Ground:
- Ground No.1 is general in nature and does not require specific adjudication.

2. Disallowance under Section 40(a)(ia) of the IT Act:
- The assessee claimed a deduction of Rs. 11,73,630 under earthwork expenses. The AO disallowed this amount as TDS was not deducted. The CIT(A) deleted the addition based on precedents, but the Supreme Court's judgment in Palam Gas Service v. CIT ruled against the assessee. The assessee did not press this ground during the appeal, leading to its dismissal.

3. Addition related to sales tax payment:
- The assessee debited Rs. 12,63,637 in the profit and loss account but provided evidence for only Rs. 8,73,605. The AO added the remaining Rs. 3,90,032, and the CIT(A) confirmed this addition. The assessee failed to provide evidence of payment before the due date for filing the return. The appeal on this ground was dismissed.

4. Addition towards staff salaries:
- The AO disallowed Rs. 25,23,182 out of Rs. 47,44,386 debited towards staff salaries due to lack of proper records and suspected inflated expenses. The CIT(A) confirmed the addition. The assessee argued that the salaries were necessary for the declared turnover of Rs. 7,84,94,244. However, the Tribunal upheld the CIT(A)'s order due to the absence of evidence like salary registers or PF/ESI contributions.

5. Disallowance of labor charges:
- The AO disallowed 10% of labor charges amounting to Rs. 9,92,136 due to lack of evidence for payment. The CIT(A) confirmed this addition. The Tribunal upheld the CIT(A)'s order as the assessee failed to furnish necessary records or evidence.

6. Addition towards creditors for expenses:
- The AO added Rs. 21,40,000 under creditors for expenses due to lack of supporting vouchers and confirmations. Out of this, Rs. 10,00,000 was for bonus payable, which is allowable on actual payment basis under Section 43B. The Tribunal confirmed Rs. 11,40,000 of the addition and remitted the bonus-related addition back to the AO for verification.

7. Addition under the head "labor charges":
- The AO disallowed Rs. 29,80,000 under labor charges, of which the CIT(A) confirmed Rs. 15,30,000 and remitted Rs. 14,50,000 back to the AO for verification. The Tribunal remitted the matter back to the AO to verify if the disallowed labor charges and the outstanding labor charges were the same or different to avoid double taxation.

8. Disallowance under Section 40(A)(3) of the IT Act:
- The AO disallowed Rs. 20,94,917 for cash payments exceeding Rs. 20,000. The CIT(A) confirmed the addition. The Tribunal remitted the issue back to the AO to identify specific payments exceeding Rs. 20,000 per person per day and disallow only those amounts, allowing the assessee to explain the reasons for such payments.

9. Alternative ground to estimate income reasonably:
- The assessee argued for income estimation due to unverifiable expenses. The Tribunal dismissed this ground, stating that the assessee maintained audited books of accounts and should not resort to estimation after defects were pointed out. The AO's method of assessment based on the books of accounts was upheld.

Conclusion:
- The appeal was partly allowed, with certain issues remitted back to the AO for further verification, while other grounds were dismissed or upheld as per the findings of the Tribunal.
