Quick summary
Income from salary is the first and usually the largest head of income for an employee. This post shows how it is worked out under the Income-tax Act, 2025 and then how tax is calculated on it, with a full example under both regimes.
Section 16 of the Act says salary includes:
Under section 15, salary due to you in the tax year is chargeable whether paid or not, salary paid in advance is chargeable in the year it is paid, and arrears paid in the year are chargeable if not taxed earlier. So salary that is due but unpaid at year end is still income of that year.
Some allowances are exempt in part or full, within limits, under Schedule III and Rule 279. The best known is house rent allowance (old regime only). It is exempt to the extent of the least of the HRA received, the rent paid less 10% of salary, and 50% of salary in Mumbai, Kolkata, Delhi, Chennai, Hyderabad, Pune, Ahmedabad and Bengaluru (40% elsewhere), where salary is basic pay plus dearness allowance if the terms provide. Leave travel concession and some others are also old regime items. See our posts on allowances for each.
Free or concessional accommodation, a car, free meals above the limit, loans at a low rate, gifts above the limit, and shares allotted under an ESOP or RSU are valued under Rule 15 and added. See our posts on perquisites and ESOP taxation.
| Deduction | Amount | Regime |
|---|---|---|
| Professional tax | The whole amount | Old only |
| Standard deduction | ₹75,000, or the salary if less | New |
| Standard deduction | ₹50,000, or the salary if less | Old |
| Death-cum-retirement gratuity of government employees | The whole amount | Both |
| Gratuity of other employees | Within the limits in our gratuity post | Both |
| Leave encashment on retirement | Government employees: the whole amount. Others: the least of the cash equivalent of leave at credit (up to 30 days for each year of service), ten times the average monthly salary of the last ten months, the notified limit and the amount received | Both |
| Voluntary retirement payment | The least of the amount received and ₹5,00,000, subject to the conditions in section 19(2)(e) | Both |
| Retrenchment compensation to a workman | The least of three amounts in the Table | Both |
The result is income from salary. If you received arrears or advance salary that pushes you into a higher slab, claim relief under section 157 with Form 39.
Add income from other heads (house property, other sources and so on), set off losses and then, in the old regime only, subtract the Chapter VIII deductions: section 123 (up to ₹1,50,000), your own NPS contribution up to ₹50,000, health insurance, education loan interest, donations and others. The new regime allows only a few of these, mainly the employer’s NPS contribution. The balance is total income.
New regime (section 202), tax year 2026-27: up to ₹4,00,000 nil; 5% to ₹8,00,000; 10% to ₹12,00,000; 15% to ₹16,00,000; 20% to ₹20,00,000; 25% to ₹24,00,000; 30% above. Rebate under section 156(2) of up to ₹60,000 if total income is up to ₹12,00,000.
Old regime: up to ₹2,50,000 nil; 5% to ₹5,00,000; 20% to ₹10,00,000; 30% above. Rebate of up to ₹12,500 if total income is up to ₹5,00,000. Higher basic exemption limits apply for resident senior citizens.
Then add surcharge if income is above ₹50 lakh, and 4% health and education cess.
Basic ₹6,00,000, HRA ₹3,00,000, special allowance ₹4,50,000, bonus ₹1,50,000. Employee’s PF ₹72,000. Rent paid ₹3,30,000 a year in Pune. Professional tax ₹2,400. Other qualifying investments ₹78,000.
| Item | Old regime (₹) | New regime (₹) |
|---|---|---|
| Gross salary | 15,00,000 | 15,00,000 |
| Less: HRA exemption (least of 3,00,000; 3,30,000 - 60,000 = 2,70,000; 50% of 6,00,000 = 3,00,000) | 2,70,000 | Not available |
| Less: professional tax | 2,400 | Not available |
| Less: standard deduction | 50,000 | 75,000 |
| Income from salary | 11,77,600 | 14,25,000 |
| Less: section 123 (PF 72,000 + others 78,000) | 1,50,000 | Not available |
| Total income | 10,27,600 | 14,25,000 |
| Tax on slabs | 1,20,780 | 93,750 |
| Add: cess at 4% | 4,831 | 3,750 |
| Tax payable | 1,25,611 | 97,500 |
The new regime costs ₹28,111 less for this employee because the deductions (₹4,72,400 in all: HRA, professional tax, standard deduction and section 123) are below the break-even for a ₹15 lakh salary. See our post on saving tax by salary level.
The employer deducts tax on salary under section 392(1) at the average rate on your estimated income for the year, after taking into account the evidence you give in Form 124 (Rule 205) and details of other income and previous employment (Form 122). It can adjust later months for any excess or shortfall (section 392(5)(c)). The employer pays the tax to the government and issues Form 130 by 15 June after the end of the year (Rule 215).
If Form 130 and your AIS differ, ask your employer to correct the TDS return before you file, or report the figures you are able to support.
Wages, any annuity or pension, gratuity, fees or commission, perquisites, profits in lieu of salary, advance salary, payment for leave not availed of, and certain provident fund and pension scheme items (section 16 of the Income-tax Act, 2025).
Under section 19(1): professional tax (old regime only), the standard deduction (₹75,000 new regime, ₹50,000 old regime), and retirement items such as gratuity, leave encashment and commutation of pension within their limits.
Yes. It is ₹75,000 or the salary, whichever is less, in the new regime, and ₹50,000 or the salary, whichever is less, in the old regime.
Form 130, the TDS certificate for salary under section 395. The employer must furnish it by 15 June after the end of the tax year (Rule 215).
Give your employer Form 124 with evidence of HRA, LTA, home loan interest and Chapter VIII claims so that TDS is deducted on the right income (section 392(5)(b), Rule 205).
In the salary schedule of the return, using Form 130 and the figures in your AIS. Reconcile any difference before filing.
