Most salaried employees in India have the same relationship with income tax ā they see a TDS deduction on their payslip every month, nod vaguely, and move on. Very few actually understand how the number was arrived at or whether they're paying more than they should. The difference between someone who actively manages their taxes and someone who doesn't can be ā¹30,000āā¹80,000 a year. That's real money.
Let's go through how it actually works.
The Biggest Choice You'll Make: Old Regime or New Regime
Since FY 2020-21, India has two parallel income tax systems running simultaneously. As of FY 2024-25, the new regime is the default ā meaning if you don't explicitly tell your employer or the IT department that you want the old regime, you get taxed under the new one automatically.
New Tax Regime ā FY 2024-25 slabs:
ā¹0 to ā¹3,00,000 ā 0%
ā¹3,00,001 to ā¹7,00,000 ā 5%
ā¹7,00,001 to ā¹10,00,000 ā 10%
ā¹10,00,001 to ā¹12,00,000 ā 15%
ā¹12,00,001 to ā¹15,00,000 ā 20%
Above ā¹15,00,000 ā 30%
The new regime has lower rates but you give up most deductions. Income up to ā¹7 lakh is effectively tax-free after the Section 87A rebate.
Old Tax Regime ā FY 2024-25 slabs:
ā¹0 to ā¹2,50,000 ā 0%
ā¹2,50,001 to ā¹5,00,000 ā 5%
ā¹5,00,001 to ā¹10,00,000 ā 20%
Above ā¹10,00,000 ā 30%
Higher rates, but you get access to deductions that can significantly lower your taxable income if you use them properly.
A Real Tax Calculation Example
Gross Salary = ā¹12,00,000
Standard Deduction = ā¹75,000
Taxable Income = ā¹11,25,000
Tax Breakdown:
ā¹0ā3L ā ā¹0
ā¹3Lā7L ā ā¹4,00,000 Ć 5% = ā¹20,000
ā¹7Lā10L ā ā¹3,00,000 Ć 10% = ā¹30,000
ā¹10Lā11.25L ā ā¹1,25,000 Ć 15% = ā¹18,750
Base Tax = ā¹68,750
Health & Education Cess (4%) = ā¹2,750
Total Tax = ā¹71,500
Our income tax calculator runs both regime calculations side by side so you can directly compare and pick what saves you more.
The Key Deductions Under the Old Regime
Section 80C ā up to ā¹1,50,000: This is the one deduction almost every salaried person uses. It includes EPF contributions (automatically deducted by employer), PPF deposits, ELSS mutual funds, tax-saving FDs, NSC, LIC premium, tuition fees for kids, and home loan principal repayment. Most people hit this limit without even trying.
If you're already investing in PPF, our PPF calculator can show you exactly how much corpus you'll build over the lock-in period ā useful for both tax planning and long-term wealth building.
Section 80D ā up to ā¹25,000: Health insurance premiums for yourself, spouse, and kids. Additional ā¹25,000 (ā¹50,000 for senior citizen parents) for your parents' health insurance. This deduction is often underutilised.
HRA ā House Rent Allowance: If you live in a rented home and your employer pays HRA, a portion of it is tax-exempt. The exemption is the lowest of: actual HRA received, 50% of basic salary (40% for non-metro), or rent paid minus 10% of basic salary. Claiming HRA properly can save significant tax for anyone paying rent in a metro city.
Section 24(b): Up to ā¹2,00,000 deduction on home loan interest for a self-occupied property. If you've taken a home loan, use our home loan calculator to see your interest component year by year ā that's what feeds into this deduction.
Section 80CCD(1B): Extra ā¹50,000 for NPS contributions ā over and above the 80C limit. So effectively, you can claim up to ā¹2 lakh in investment deductions by combining 80C and 80CCD(1B).
Which Regime Should You Actually Choose?
This is a purely mathematical decision. The old regime wins when your deductions are large enough to reduce taxable income below what the new regime's lower rates can offset. The new regime wins when you don't invest much or can't claim significant deductions.
A rough thumb rule: if your total deductions exceed ā¹3ā3.5 lakh, the old regime usually saves more tax. Below that, the new regime's lower rates are better. But don't rely on the thumb rule ā use the calculator and compare the actual numbers for your specific situation.
Standard Deduction: Free Money You Don't Have to Do Anything For
Both regimes now offer a flat ā¹75,000 standard deduction for FY 2024-25 (increased from ā¹50,000 in Budget 2024). Every salaried employee and pensioner gets this automatically ā no investment, no proof, no effort. It's deducted straight from your gross salary before tax is calculated.
The Salary Calculator Connection
Income tax is just one part of understanding your take-home pay. Our salary calculator breaks down your complete CTC into gross salary, PF deduction, professional tax, TDS, and actual in-hand amount ā giving you the full picture in one place.
Don't Miss the July 31 Deadline
ITR filing deadline for salaried individuals is July 31 each year for the previous financial year. Missing it means a late fee (ā¹5,000, or ā¹1,000 if income is below ā¹5 lakh), interest on any unpaid tax, and loss of certain carry-forward benefits. It's worth doing it on time even if you don't owe any additional tax.
What is the income tax exemption limit for FY 2024-25?
Under the new regime, income up to ā¹7 lakh is effectively tax-free due to the 87A rebate. Under the old regime, it's ā¹5 lakh. The basic exemption limits (before rebate) are ā¹3 lakh (new) and ā¹2.5 lakh (old).
Can I switch between old and new regime every year?
Salaried employees and pensioners can switch regimes every year when filing their ITR. Individuals with business income can only switch back to the old regime once in their lifetime ā so that decision needs more careful thought.
Is PF contribution eligible for 80C deduction?
Yes ā your own EPF contribution is deductible under 80C up to the ā¹1.5 lakh limit. Your employer's contribution is not counted in your income at all, so it doesn't factor into 80C.
What happens if I don't file ITR?
A late fee of ā¹5,000 applies (ā¹1,000 if income is below ā¹5 lakh). Repeated non-filing can attract scrutiny notices, interest on tax dues, and penalties. Some deductions and losses also can't be carried forward if the return isn't filed on time.
Is agricultural income taxable?
Agricultural income itself is exempt under Section 10(1). However, it's factored into your total income to determine the applicable tax rate on your non-agricultural income ā a concept called partial integration. So having agricultural income can indirectly increase the tax rate on your other income.
Tax planning isn't complicated once you understand the structure. Use the income tax calculator to compare both regimes for your income level, then decide based on actual numbers rather than guesswork.
