Income Tax for Salaried Employees in India: New vs Old Regime (FY 2025-26)

Income tax is one of the most confusing aspects of personal finance for salaried employees in India — especially since the government introduced the new tax regime and has been tweaking the rules every year. This guide cuts through the confusion and gives you a clear, practical understanding of how your salary gets taxed in FY 2025-26.

The Two Tax Regimes in India

Since FY 2020-21, Indian taxpayers have a choice between two regimes:

New Tax Regime (Default from FY 2023-24)

Lower tax rates — see slab table below
Simpler — very few deductions and exemptions allowed
Recommended for: People with fewer deductions (young earners, those without home loans or heavy 80C investments)

Old Tax Regime (Optional — must be chosen at filing)

Higher headline rates but allows many deductions and exemptions
Can significantly reduce tax if you have: home loan, HRA, 80C investments, NPS, medical insurance
Recommended for: Salaried people with home loans, HRA, and systematic 80C/80D investments

FY 2025-26 New Tax Regime — Revised Slabs

The Union Budget 2025 further sweetened the new regime. The key headline change: no tax up to ₹12 lakh (after the ₹75,000 standard deduction, effective zero tax up to ₹12.75 lakh for salaried).

| Income Slab | Tax Rate | |-------------|----------| | Up to ₹4,00,000 | NIL | | ₹4,00,001 – ₹8,00,000 | 5% | | ₹8,00,001 – ₹12,00,000 | 10% | | ₹12,00,001 – ₹16,00,000 | 15% | | ₹16,00,001 – ₹20,00,000 | 20% | | ₹20,00,001 – ₹24,00,000 | 25% | | Above ₹24,00,000 | 30% |

Standard deduction under new regime: ₹75,000 (from FY 2024-25 onwards)
Rebate under Section 87A: Full tax rebate if income ≤ ₹12,00,000 (making effective zero tax up to ₹12,75,000 after standard deduction)

Health and Education Cess: 4% on the calculated tax

Quick Tax Calculation Examples (New Regime)

Example 1 — Annual CTC ₹10 lakh (Gross ₹10L, net taxable ₹9.25L after ₹75K standard deduction)

Up to ₹4L: ₹0
₹4L–₹8L: 5% of ₹4L = ₹20,000
₹8L–₹9.25L: 10% of ₹1.25L = ₹12,500
Total before cess: ₹32,500
Since ₹9.25L ≤ ₹12L, rebate under 87A applies → Tax = ₹0
Effective tax = ₹0

Example 2 — Annual gross ₹18 lakh (taxable ₹17.25L after standard deduction)

Up to ₹4L: ₹0
₹4L–₹8L: ₹20,000
₹8L–₹12L: ₹40,000
₹12L–₹16L: 15% of ₹4L = ₹60,000
₹16L–₹17.25L: 20% of ₹1.25L = ₹25,000
Total: ₹1,45,000 + 4% cess = ₹1,50,800

Example 3 — Annual gross ₹30 lakh

Up to ₹4L: ₹0
₹4L–₹8L: ₹20,000
₹8L–₹12L: ₹40,000
₹12L–₹16L: ₹60,000
₹16L–₹20L: ₹80,000
₹20L–₹24L: ₹1,00,000
₹24L–₹29.25L (after ₹75K standard deduction): 30% of ₹5.25L = ₹1,57,500
Total: ₹4,57,500 + 4% cess = ₹4,75,800

Old Tax Regime — Slabs and Key Deductions

| Income Slab | Tax Rate | |-------------|----------| | Up to ₹2,50,000 | NIL | | ₹2,50,001 – ₹5,00,000 | 5% | | ₹5,00,001 – ₹10,00,000 | 20% | | Above ₹10,00,000 | 30% |

The old regime looks worse on paper, but the deductions can dramatically reduce taxable income.

Key Deductions Under the Old Regime

Section 80C — Up to ₹1,50,000 deduction Eligible investments and expenses:

EPF (Employee Provident Fund) — automatically deducted from salary
PPF contributions
ELSS (Tax-saving mutual funds) — 3-year lock-in, market-linked
Life insurance premium
NSC (National Savings Certificate)
5-year tax-saving FD
Principal repayment on home loan
Children's school tuition fees

Section 80D — Medical Insurance Premium

Up to ₹25,000 for self + family
Additional ₹25,000 for parents (₹50,000 if parents are senior citizens)
Total: Up to ₹75,000 deduction

HRA (House Rent Allowance) Exemption If you receive HRA as part of your salary and pay rent, you can claim exemption. The exemption is the minimum of:

Actual HRA received
50% of basic salary (metro cities) or 40% (non-metro)
Actual rent paid minus 10% of basic salary

Example: Basic salary ₹50,000/month, HRA received ₹20,000/month, actual rent paid ₹18,000/month (Mumbai)

HRA received = ₹20,000
50% of basic = ₹25,000
Rent − 10% of basic = ₹18,000 − ₹5,000 = ₹13,000 → Exemption = ₹13,000/month = ₹1,56,000 annually

Section 80CCD(1B) — NPS Contribution Additional ₹50,000 deduction for contributions to National Pension System — over and above 80C limit.

Section 24(b) — Home Loan Interest Up to ₹2,00,000 deduction on interest paid on home loan for self-occupied property.

Leave Travel Allowance (LTA) Travel expenses for domestic journeys (twice in 4-year block) are exempt from tax.

Standard Deduction (Old Regime): ₹50,000

New vs Old Regime: Which is Better for You?

The break-even point depends on your deductions. Here's a practical comparison at ₹18 lakh gross income:

| | New Regime | Old Regime | |--|------------|------------| | Gross Income | ₹18,00,000 | ₹18,00,000 | | Standard Deduction | ₹75,000 | ₹50,000 | | 80C investments | Not allowed | ₹1,50,000 | | Home Loan Interest (24b) | Not allowed | ₹2,00,000 | | NPS 80CCD(1B) | Not allowed | ₹50,000 | | 80D (health insurance) | Not allowed | ₹25,000 | | Taxable Income | ₹17,25,000 | ₹13,25,000 | | Tax (approx.) | ₹1,50,800 | ₹81,000 |

At ₹18 lakh income with a home loan and good 80C investments, the old regime saves ₹70,000 in this example.

General Rule of Thumb

Stick with New Regime if:

Income below ₹7.75 lakh (zero tax anyway under 87A)
No home loan, no HRA, minimal 80C deductions
You find the old regime too complicated
Your total deductions are under ₹3–3.5 lakh

Consider Old Regime if:

You have an active home loan (₹2L interest deduction + 80C principal)
You pay significant rent and get HRA
You maximise 80C (EPF + PPF + ELSS) + 80D + NPS
Total deductions exceed ₹4–5 lakh

Understanding Your Salary Slip Components

For salaried employees, tax is deducted monthly by the employer as TDS (Tax Deducted at Source). Here are the key components:

| Component | Taxable? | Notes | |-----------|----------|-------| | Basic Salary | Yes | Typically 40–50% of CTC | | HRA | Partially | Exempt if you pay rent (see formula above) | | Special Allowance | Yes | Fully taxable | | LTA | Partially | Exempt for travel, twice in 4 years | | Meal Coupons | Partially | ₹50/meal exempt (Sodexo etc.) | | EPF Employer Contribution | No (up to limit) | Exempt up to 12% of basic | | Gratuity | Partially | Exempt up to ₹20 lakh | | Bonus / Incentive | Yes | Fully taxable | | ESOP (on exercise) | Yes | Taxed as perquisite |

Submitting Investment Declarations (Form 12BB)

At the start of each financial year, your employer asks you to submit Form 12BB — an investment declaration stating what 80C, 80D, HRA, and other deductions you plan to claim.

Important: This declaration is just an estimate. You must submit actual proof (investment receipts, rent receipts) to your employer by January 31 of the financial year. Failure to submit proofs means the employer will deduct higher TDS in the last 2 months of the year.

Filing Your ITR (Income Tax Return)

Even if your employer deducted the correct TDS, filing your ITR is mandatory if your gross income exceeds ₹2.5 lakh. The due date is typically July 31 for salaried individuals (without audit requirement).

Key ITR forms for salaried individuals:

ITR-1 (Sahaj): Single employer salary + one house property + bank interest — simplest
ITR-2: Multiple income sources, capital gains, more than one house property

File through: www.incometax.gov.in — free and takes about 20–30 minutes for simple returns.

Key Takeaways

New regime default from FY 2023-24; no tax up to ₹12.75L (salaried) after 87A rebate
Old regime is better if total deductions exceed ~₹3.5L (home loan + 80C + HRA)
Always compare both regimes with your actual numbers before choosing
Submit Form 12BB early and investment proofs by January 31
File your ITR by July 31 — even if TDS is fully paid, filing is mandatory
ELSS is the best 80C option if you want market-linked returns with 3-year lock-in
