Quick answer: Basic salary is the fixed core of your pay, before allowances, bonuses and deductions. It is fully taxable, and it is the base for PF, gratuity, HRA exemption and often leave encashment. No law fixes it at 50% of CTC, but under the Labour Codes, wages for PF and gratuity cannot fall below half of total remuneration, so a very low basic no longer reduces those contributions.
Basic salary is the first line on almost every Indian payslip, and the number most other figures are worked out from. This guide explains what basic salary means, how it differs from gross, net and CTC, how much it usually is, how to calculate it (monthly, daily and pro rata), and exactly what it affects. It is part of our salary structure guide.
What is basic salary?
Basic salary (also called basic pay) is the fixed amount an employer pays for the job, before any allowances, perks, overtime, bonus or deductions. It is agreed in the offer or appointment letter, stays the same every month until the next revision, and is the same whether or not the employee claims any allowances.
A few related terms:
- Full basic salary is the basic for a full month with no loss of pay.
- Monthly basic salary is the annual basic divided by 12.
- Basic + DA is how basic is usually quoted in government jobs and in industries with a dearness allowance, because the two together form the wage base.
- Base salary, a term common in multinational offers, usually means total fixed pay, not basic salary. Check the annexure to see which is meant.
Basic salary vs gross salary vs net salary vs CTC
The four numbers are easiest to see in one example. This company pays PF on the ₹25,000 ceiling and keeps gratuity outside CTC:
| Monthly (₹) | Amount | What it is |
|---|---|---|
| Basic salary | 20,000 | The fixed core of pay |
| HRA | 10,000 | Allowance, here 50% of basic |
| Special allowance | 15,000 | Balancing allowance |
| Gross salary | 45,000 | Basic + all allowances |
| Employer PF | 3,000 | Paid by the employer, not through the payslip |
| CTC | 48,000 | Gross + employer contributions |
| Less employee PF | 3,000 | Deducted from gross |
| Net salary before PT and TDS | 42,000 | What reaches the bank, before tax deductions |
Here basic is about 42% of CTC and 44% of gross. So basic is never the same as gross or net: gross adds the allowances, and net takes off the deductions. To split any CTC this way, use the salary breakup calculator; our guides to CTC and gross vs net salary explain the other three numbers.
How much should basic salary be?
There is no legal percentage for basic salary. In practice employers set it as a share of CTC or gross pay, and the choice is a trade-off: a higher basic means more PF and gratuity for the employee but lower take-home pay, while a lower basic does the opposite.
Two rules limit how low basic can go in practice:
- Minimum wages. Minimum wages are notified for basic pay, often with a variable DA added. Basic + DA should be at least the minimum wage for the employee's state, zone and skill level under the Code on Wages, 2019; allowances such as HRA should not be relied on to make up the shortfall. Some states are explicit: Haryana's 2026 minimum wages are basic rates that cannot be split into allowances. See minimum wages in India.
- The 50% wage rule. Since 21 November 2025, if excluded items such as HRA, conveyance, employer PF and statutory bonus exceed half of total remuneration (see the Labour Ministry FAQs), the excess counts as wages for PF, gratuity and bonus. This does not make 50% basic mandatory, but a basic far below half no longer lowers those contributions.
So: basic can be less than 50% of CTC, and it can be more (even 70%). It cannot be below the minimum wage. Our guide to the 50% basic salary rule and salary restructuring covers the rule and the employer's options in detail.
How to calculate basic salary
Basic salary is set by the employer, so "calculating" it usually means one of four things. In practice payroll software or a spreadsheet does the arithmetic; see our comparison of payroll software in India if you are choosing a payroll app.
From CTC or gross salary
Basic = CTC (or gross) × the company's basic percentage. With a CTC of ₹6,00,000 a year and basic at 40% of CTC, basic is ₹2,40,000 a year, or ₹20,000 a month.
How to check your basic salary
Your basic salary is shown in three places: the salary annexure to your offer or appointment letter (usually as an annual figure), the first earnings line on your monthly payslip, and the salary details in your payroll portal. To see what share of CTC it is, divide annual basic by annual CTC.
Daily basic salary
Daily basic = monthly basic ÷ the company's divisor. With a basic of ₹20,000, that is ₹666.67 on a 30-day divisor or ₹769.23 on 26 days. The divisor is company policy (calendar days, 30 or 26), and it should be the same one used for every component.
Pro rata basic salary
For a part month, after joining, leaving or loss of pay: basic paid = monthly basic × paid days ÷ days in the divisor. Two days of loss of pay in a 30-day month on a basic of ₹20,000 gives ₹20,000 × 28 ÷ 30 = ₹18,667. Loss of pay reduces every component paid for days, not only basic. The monthly salary calculator does this for the whole salary.
Total salary from basic
To go the other way, from basic to gross, add each allowance. If HRA is 50% of basic and other allowances are fixed amounts, gross = basic × 1.5 + other allowances. Our salary structure format shows a full annexure.
What basic salary affects
Basic is the anchor for most statutory and tax calculations, which is why it matters more than its size suggests:
| Item | How basic is used |
|---|---|
| Provident fund | 12% each from employee and employer on PF wages (basic, DA and allowances not on the exclusion list, plus any 50% add-back), up to the ₹25,000 ceiling if the employer restricts it |
| Gratuity | Last drawn wages × 15 × completed years ÷ 26 |
| HRA exemption (old regime) | Exempt amount is the least of: HRA received; rent paid minus 10% of basic + DA; and 50% of basic + DA in the eight listed cities (Delhi, Mumbai, Kolkata, Chennai, Bengaluru, Hyderabad, Pune, Ahmedabad) or 40% elsewhere |
| Employer NPS | Deductible up to 14% of basic + DA in the new regime |
| Statutory bonus | Eligibility and calculation use wages, which start from basic |
| Leave encashment, overtime, increments | Often worked out on basic or wages, depending on the law and company policy |

Basic salary in the payroll journal entry
In the books, basic salary is not entered on its own: the month's total earnings (basic plus allowances) are debited to a salary expense account, and the deductions and net pay are credited to PF payable, professional tax payable, TDS payable and salary payable. Our EPF guide shows a full salary journal entry with PF for one employee.
Is basic salary taxable?
Yes. Basic salary is fully taxable under both tax regimes. Income tax is not worked out on basic alone, though: TDS is calculated on your total taxable salary for the year (basic, taxable allowances and perquisites), after the standard deduction and any exemptions your regime allows. Our guide to TDS on salary explains the method.
Special allowance vs basic salary
Special allowance is a separate component, usually the balancing figure that makes up the agreed gross pay. It is not part of basic salary, and it can be larger than basic. Two points matter, though:
- Under the Labour Codes, special allowance is not on the list of excluded allowances, so it is generally treated as wages along with basic for PF, gratuity and bonus. This is the widely held reading; the law does not name special allowance either way.
- Special allowance is fully taxable, like basic, so moving money between the two does not change income tax.
Can basic salary be reduced or increased?
Basic salary can be increased at any revision, and employers often review it once a year, but there is no legal right to an annual increase in the private sector. Reducing basic is different. A reduction changes the conditions of service: for workers, wages and allowances can only be changed after 21 days' notice under the Industrial Relations Code, and the Code on Social Security forbids reducing wages only to avoid PF or other contributions. For other employees, a reduction needs to be agreed under the employment contract.
Basic pay in government jobs
Central government basic pay comes from the 7th Pay Commission pay matrix: for example, ₹18,000 at Level 1 and ₹19,900 at Level 2. It rises by an annual increment of 3% and on promotion, and DA, HRA and other allowances are worked out as percentages of basic. See the DA calculator and our Pay Level 2 salary guide for worked figures.

Frequently asked questions
Is basic salary the same as gross salary?
No. Basic salary is one component of pay. Gross salary is basic plus all allowances paid through the payslip, such as HRA and special allowance, before any deductions.
Can basic salary be 70% of CTC?
Yes. No law caps basic salary. A higher basic means higher PF (unless PF is restricted to the ₹25,000 ceiling), higher gratuity and a lower take-home within the same CTC, and it leaves less room for HRA, which only helps employees in the old tax regime.
Can basic salary change every month?
Basic salary is fixed and changes only when your pay is revised. What changes month to month is the amount paid: loss-of-pay days reduce the basic actually paid for that month, and arrears from a back-dated revision increase it.
What happens if my basic salary is more than ₹25,000?
PF is calculated on wages, and the PF wage ceiling has been ₹25,000 a month since 17 September 2026 (₹15,000 before that). If your PF wages are above the ceiling, your employer may restrict PF to ₹3,000 a month (12% of ₹25,000). If you were never a PF member and joined with PF wages above ₹25,000, PF is not mandatory for you.
Is special allowance part of basic salary?
No. Special allowance is a separate component. But under the Labour Codes it is generally counted as wages, along with basic, for PF, gratuity and bonus, because it is not on the list of excluded allowances. This is the widely held reading; the law does not name special allowance either way.
