A salaried engineer is taxed under "Salaries": the employer deducts TDS under Section 192, issues Form 16, and the engineer files ITR-1. Under the default new regime for FY 2025-26, a salaried engineer pays nil tax up to about Rs12.75 lakh (Rs12 lakh rebate + Rs75,000 standard deduction). A freelance / consulting engineer is taxed under business/profession income and can opt for Section 44ADA — 50% of gross receipts up to Rs75 lakh is deemed income — filing ITR-4. Clients deduct TDS under Section 194J (2% technical / 10% professional).
How an Engineer's Income is Taxed
Your income head, TDS section and ITR form all depend on whether you draw a salary, freelance, or do both.
| Engineer type | Income head | TDS section | ITR form | 44ADA? |
|---|---|---|---|---|
| Salaried engineer (employee) | Salaries | Sec 192 (employer) | ITR-1 / ITR-2 | No |
| Freelance / consulting engineer | Business & profession | Sec 194J — 2% / 10% | ITR-4 (Sugam) | Yes |
| Salaried + freelance (dual) | Salaries + profession | Sec 192 + 194J | ITR-3 | On freelance |
| Salaried with capital gains | Salaries + capital gains | Sec 192 | ITR-2 | No |
| Engineering partnership firm | Business (PGBP) | Sec 194J (from clients) | ITR-5 | Yes |
| Software engineer (freelance) | Profession | Sec 194J — 2% | ITR-4 / ITR-3 | Yes |
Software engineers follow the same rules as other engineers. Verify the current ITR schema each year on incometax.gov.in.
Income Tax Slabs That Apply to Engineers
The new regime is the default from FY 2025-26. Thanks to the Section 87A rebate, a resident individual pays nil tax up to Rs12 lakh of taxable income; with the Rs75,000 standard deduction, a salaried engineer effectively pays nil up to about Rs12.75 lakh of salary. The old regime stays optional for those with large 80C / home-loan / HRA deductions.
| Taxable income (new regime) | Rate |
|---|---|
| Up to Rs4,00,000 | Nil |
| Rs4,00,001 – Rs8,00,000 | 5% |
| Rs8,00,001 – Rs12,00,000 | 10% |
| Rs12,00,001 – Rs16,00,000 | 15% |
| Rs16,00,001 – Rs20,00,000 | 20% |
| Rs20,00,001 – Rs24,00,000 | 25% |
| Above Rs24,00,000 | 30% |
Plus 4% health & education cess and surcharge for higher incomes (surcharge capped at 25% under the new regime). Section 87A rebate makes tax nil up to Rs12,00,000 taxable income.
New regime — default
- Nil tax up to Rs12L taxable (87A)
- Standard deduction Rs75,000
- Lower slab rates
- No 80C / HRA / 24(b) self-occupied
- Best for most salaried engineers
Old regime — optional
- Standard deduction Rs50,000
- 80C up to Rs1.5L, 80D, 80CCD(1B)
- Home-loan interest 24(b) up to Rs2L
- HRA exemption available
- Worth it only with large deductions

Compare Old vs New →Salaried Engineer — Deductions & Planning
Salaried engineers get Form 16 showing TDS deducted under Section 192. The employer computes TDS on projected annual income after your declared deductions. Key deductions available:
- Standard deduction — Rs75,000 (new regime) or Rs50,000 (old); automatic, no proof needed. See Form 16.
- Section 80C (old regime only) — up to Rs1.5L: EPF, PPF, ELSS, LIC, home-loan principal. See Section 80C.
- Home-loan interest 24(b) — up to Rs2L on a self-occupied house (old regime only).
- NPS 80CCD(1B) — extra Rs50,000; plus employer NPS under 80CCD(2) is allowed even in the new regime.
- Section 80D — health-insurance premium (old regime). See Section 80D.
Salaried employees — including software engineers working from home — cannot deduct internet, electricity, laptops or home-office costs. The Rs75,000 standard deduction is the flat allowance meant to cover such incidentals. Only freelancers claim actual expenses (or use 44ADA).

File Salaried ITR →Freelance Engineer — Section 44ADA
Engineering is a notified profession under Section 44AA, so freelance engineers can use Section 44ADA presumptive taxation. If gross professional receipts are up to Rs75 lakh, just 50% is deemed net income — no books of account and no tax audit needed. The other 50% is presumed to cover all expenses (software, AutoCAD, travel, site visits).
Freelance engineer · Rs30L receipts (44ADA)
Same engineer · new-regime tax
Above Rs75 lakh of receipts you must maintain books and a tax audit under Section 44AB may apply. Non-residents cannot opt for 44ADA. A freelancer opting for 44ADA files ITR-4; if you also draw a salary, use ITR-3.
A salaried software engineer who takes side projects must report both incomes and cannot use ITR-4 — file ITR-3, with 44ADA applied to the freelance portion. Pay advance tax if total liability after TDS exceeds Rs10,000.

File Freelance ITR →TDS on Engineering Fees — Section 194J
Engineering consultancy is a professional / technical service under Section 194J, not 194C (contractors). Clients deduct TDS before paying you; claim the credit via Form 26AS / AIS when filing.
| Nature of payment | TDS rate | Threshold | Notes |
|---|---|---|---|
| Technical services (design, consulting) | 2% | Rs30,000/yr | Reduced from 10% (Finance Act 2020) |
| Professional services (certification) | 10% | Rs30,000/yr | When primarily a professional service |
| Royalty (patents, know-how, designs) | 10% | Rs30,000/yr | Licensing of designs / technology |
| Contract work (194C, sub-contract) | 1% / 2% | Rs30k / Rs1L | Contractual work, not consultancy |
Always match TDS in Form 26AS and AIS before filing your ITR.
Which ITR Form Should an Engineer File?
| Engineer profile | Correct ITR form |
|---|---|
| Salaried only, income < Rs50L, no capital gains | ITR-1 (Sahaj) |
| Salaried with capital gains (stocks, MF, property) | ITR-2 |
| Salaried + freelance (both incomes) | ITR-3 |
| Freelance only, opted for 44ADA | ITR-4 (Sugam) |
| Engineering partnership firm | ITR-5 |
GST for Freelance Engineers
A freelance engineer must take GST registration once aggregate turnover crosses Rs20 lakh (Rs10 lakh in special-category states), then charges 18% GST on Indian invoices and files GSTR-1 and GSTR-3B. Export of services can be zero-rated (with LUT / FIRC). Many engineers register voluntarily so corporate clients can claim ITC.
The Rs75 lakh 44ADA limit is an income-tax rule; the Rs20 lakh GST threshold is separate. A freelance engineer between Rs20L and Rs75L can use 44ADA for income tax AND must register for GST at the same time.
