Quick answer
Salaried civil engineers use the regime choice, HRA, 80C and NPS; consulting engineers get 44ADA. Here's how civil engineers save tax.
The new regime gives a Rs 75,000 standard deduction and nil tax up to Rs 12,00,000 with few deductions; the old regime wins only if your HRA, 80C, NPS and 80D together beat that. Run both each year, especially if you also consult on the side.
If you work as an independent consulting engineer with professional receipts within Rs 50 lakh (Rs 75 lakh where cash is 5% or less), Section 44ADA lets you declare 50% of receipts as income with no audit — often simpler and lighter than full books.
If you claim actuals, deduct site travel and accommodation, instruments and software (through depreciation), drawing and survey costs, and a share of office and communication. These are real for a working civil engineer and reduce taxable income.
In the old regime, use 80C up to Rs 1,50,000, then add the Rs 50,000 NPS under 80CCD(1B). If salaried with employer NPS under 80CCD(2), that contribution is deductible too — and survives in the new regime.
With no employer TDS on consulting income, pay advance tax in the four instalments if your tax exceeds Rs 10,000, to avoid 234B/234C interest. Salaried engineers with side projects should top up advance tax for the extra.
