Tax Planning for Salaried Employees: Old vs New Regime and How to Save Maximum Tax

The Big Question: Old Regime or New Regime?

Every salaried employee in India faces this question every year: should I choose the old tax regime or the new one? The answer is not the same for everyone — it depends on how many deductions you can claim.

Here is the simple rule: the old regime only wins once your total deductions get large — roughly ₹5.9 lakh at a ₹15 lakh salary, and about ₹7.6 lakh at ₹20 lakh (including the standard deduction). Below that, the new regime's lower slabs and the enhanced Section 87A rebate win. Note the new regime is now the default under Section 115BAC — you must actively opt out to use the old one.

Tax Slabs Comparison (FY 2025-26)

Income Slab	Old Regime	New Regime
Up to ₹2.5 lakh / ₹4 lakh	0%	0%
₹2.5L - ₹5L / ₹4L - ₹8L	5%	5%
₹5L - ₹10L / ₹8L - ₹12L	20%	10%
₹10L - ₹12L / ₹12L - ₹16L	30%	15%
Above ₹10L / ₹16L - ₹20L	30%	20%
₹20L - ₹24L	30%	25%
Above ₹24L	30%	30%

The new regime has lower rates and more slabs, but allows almost no deductions. The old regime has higher rates but lets you claim HRA, 80C, 80D, home loan interest, and more.

Key Deductions in the Old Regime

Section 80C — Up to ₹1.5 lakh

The most popular tax-saving section. Investments that qualify: EPF (automatic for salaried), PPF, ELSS mutual funds, life insurance premiums, children's tuition fees, NSC, tax-saver FDs, and home loan principal. Use our SIP Calculator to plan ELSS investments.

Section 80D — Health Insurance

Deduction for health insurance premiums: ₹25,000 for self and family, additional ₹25,000 for parents (₹50,000 if parents are senior citizens). Maximum: ₹1 lakh if you and your parents are both senior citizens.

HRA Exemption — Section 10(13A)

If you live in a rented house and receive HRA as part of your salary, you can claim exemption. The exempt amount is the lowest of: actual HRA received, 50% of basic salary (metro) or 40% (non-metro), or rent paid minus 10% of basic salary.

Section 80CCD(1B) — NPS Extra ₹50,000

An additional ₹50,000 deduction for NPS contributions, over and above 80C. Read our detailed NPS tax hack guide.

Section 24(b) — Home Loan Interest

Deduction of up to ₹2 lakh per year on home loan interest for self-occupied property. See our home loan guide for details.

Quick Decision Tool: Which Regime Is Better for You?

Add up your total deductions (80C + 80D + HRA + NPS + home loan interest + any others):

• Total deductions below ₹5 lakh: the new regime is almost certainly better
• ₹5L - ₹6L: close call at a ₹15L salary — compare both with our Tax Calculator
• Above ₹6 lakh: the old regime starts to win, and the threshold rises with your salary (about ₹7.6 lakh at ₹20 lakh)

Month-by-Month Tax Planning Calendar

Month	Action
April	Declare regime choice and investment proofs to employer
June	Start ELSS SIP if using 80C; pay health insurance premium
September	Pay advance tax (2nd instalment) if applicable
December	Submit investment proofs to HR; make final 80C investments
January	Check Form 16 Part B; verify TDS deductions
March	Last chance for PPF, NPS, insurance premium payments
July	File ITR before deadline; claim refund if excess TDS deducted

5 Tax-Saving Mistakes Salaried Employees Make

1. Not submitting investment proofs on time — your employer deducts higher TDS; you get refund only after filing ITR months later
2. Over-investing in life insurance for tax saving — endowment plans give 4-5% returns. ELSS gives 12%+ and saves the same tax
3. Ignoring HRA exemption — if you pay rent but do not claim HRA, you are losing a major deduction
4. Not claiming NPS 80CCD(1B) — extra ₹50,000 deduction that most people miss
5. Choosing the wrong regime — always calculate both before declaring to your employer

The New Regime Is Now the Default — Start From There

The single most important fact for FY 2025-26 (AY 2026-27) is one that most tax-planning advice still skips: the new regime under Section 115BAC(1A) is the default. If you say nothing to your employer, you are taxed under the new regime. The old regime is now the opt-in choice, and salaried employees can switch between the two every year at the time of filing.

That inversion matters because almost every "tax saving tip" written before FY 2023-24 assumes the old regime. Buying an ELSS fund in March or topping up a life insurance premium reduces your tax by nothing at all if you are on the default regime. Settle the regime question first, with our old vs new tax regime comparison.

Zero Tax Up to ₹12.75 Lakh: How the ₹60,000 Rebate Works

From AY 2026-27, the Section 87A rebate under the new regime rose from ₹25,000 to ₹60,000, and the income ceiling for it moved from ₹7 lakh to ₹12 lakh of total income. Because a salaried person also gets the ₹75,000 standard deduction, a salary of ₹12.75 lakh lands at ₹12 lakh of taxable income and attracts nil tax.

On ₹12 lakh of taxable income: nil on the first ₹4 lakh, ₹20,000 on the ₹4–8 lakh slab, ₹40,000 on the ₹8–12 lakh slab — ₹60,000 of tax, wiped out entirely by the ₹60,000 rebate.

Cross ₹12 lakh and the rebate does not vanish in a cliff. Marginal relief caps your tax at the amount by which income exceeds ₹12 lakh: on ₹12.10 lakh of taxable income the slab tax is ₹61,500, but relief limits it to the ₹10,000 of excess, so you pay ₹10,400 including cess. Detail is in our Section 87A rebate guide.

Two traps: the rebate is unavailable to non-residents, and it does not apply to income taxed at special rates such as capital gains under Section 112A.

Salary Structuring That Still Works Under the New Regime

Deductions are mostly gone, but salary structuring is not. These items reduce taxable salary at source and survive the default regime. This is where a salaried employee on the new regime has real, legal room to move.

Employer NPS Contribution — Section 80CCD(2)

This is the standout. Under the new regime, an employer's contribution to your NPS Tier-I account is deductible up to 14% of salary (basic + dearness allowance) for every employer, government or private. Under the old regime the same limit is 10% for non-government employers, and 14% only for government employees.

On a basic of ₹60,000 a month (₹7.2 lakh a year), a 14% employer contribution is ₹1,00,800 that never enters taxable income — roughly ₹21,000 of tax saved at a 20% marginal rate, about ₹31,500 at 30%, every year, with no March scramble. Ask HR whether a corporate NPS facility exists; many employers will restructure an existing allowance into it at no extra cost. This is distinct from the ₹50,000 self-contribution under 80CCD(1B), which is old-regime only.

Employer EPF, Gratuity and Leave Encashment

Your employer's EPF contribution up to 12% of salary stays outside taxable income under both regimes. One ceiling applies jointly: employer contributions to recognised PF, NPS and an approved superannuation fund that together exceed ₹7.5 lakh in a year are taxable as a perquisite under Section 17(2)(vii), along with the accretion on the excess. High earners layering a large NPS contribution on top of EPF should check this line.

Gratuity remains exempt up to ₹20 lakh for non-government employees under Section 10(10), and leave encashment on retirement is exempt up to ₹25 lakh under Section 10(10AA). Both survive the new regime. Voluntary retirement compensation under Section 10(10C) does too.

Reimbursements and Allowances That Remain Exempt

Section 10(14) read with Rule 2BB keeps a narrow set of allowances exempt under the new regime, provided they are genuinely spent for the stated purpose:

• Conveyance allowance for travel in the course of official duty — not your daily home-to-office commute
• Tour and transfer allowance covering travel or relocation on posting
• Daily allowance for ordinary expenses when you are away from your normal place of duty
• Transport allowance for an employee who is blind, deaf and dumb, or orthopaedically handicapped

What is gone under the new regime: HRA, LTA, the children's education allowance, professional tax under Section 16(iii), and the entire 80C/80D/80CCD(1B)/24(b) stack. Our guide to the deductions you lose in the new regime lists them in full.

The Old Regime: Who It Still Suits, With the Real Breakeven

The old regime is not dead — it is just far harder to justify than it was. Its slabs (nil to ₹2.5 lakh, 5% to ₹5 lakh, 20% to ₹10 lakh, 30% above) are unchanged, the standard deduction is ₹50,000, and the 87A rebate there is still only ₹12,500 up to ₹5 lakh of income.

Do the arithmetic on a ₹15 lakh salary. Under the new regime, taxable income is ₹14.25 lakh and the tax works out to ₹93,750 plus 4% cess — ₹97,500. To match that under the old regime you need taxable income down to about ₹9.06 lakh, which means roughly ₹5.94 lakh of total deductions including the standard deduction. A conventional stack of ₹50,000 standard deduction, ₹1.5 lakh under 80C, ₹25,000 under 80D and ₹50,000 under 80CCD(1B) comes to ₹2.75 lakh — leaving a tax bill of ₹1,87,200, nearly ₹90,000 worse.

In practice only two things get you across that line: a large HRA claim or home loan interest under Section 24(b). Below ₹12.75 lakh of salary the old regime cannot win at all, because the new regime already charges nothing.

HRA, Worked Through

Suppose basic salary is ₹7.2 lakh a year, HRA received is ₹3.6 lakh, rent paid in Delhi is ₹25,000 a month (₹3 lakh a year). The exemption is the lowest of three figures: actual HRA received (₹3.6 lakh); 50% of basic for a metro (₹3.6 lakh); rent paid minus 10% of basic (₹3,00,000 − ₹72,000 = ₹2,28,000). The lowest is ₹2,28,000 exempt, leaving ₹1,32,000 of HRA taxable. Add ₹2 lakh of home loan interest and the old regime starts to make sense. Keep rent receipts, and quote your landlord's PAN if annual rent exceeds ₹1 lakh. For the wider old-regime toolkit, see how to save tax beyond 80C.

Run both numbers on our income tax calculator before you declare — and re-run them every year, because a salary hike, a home loan closing, or a move out of rented accommodation can flip the answer.

The Four Dates That Decide Your Tax Bill

Deadline	What you must do	Cost of missing it
April (start of FY)	Declare your regime choice and estimated investments to your employer	Payroll defaults you to the new regime and sets TDS accordingly
15 Jun / 15 Sep / 15 Dec / 15 Mar	Advance tax instalments (15%, 45%, 75%, 100% cumulative) if salary TDS does not cover income from interest, rent or capital gains	Interest under Sections 234B and 234C
December–January	Submit actual investment proofs to HR	Higher TDS for the rest of the year; refund only after you file
31 March	Last day to make the year's PPF, NPS or insurance payments count	The deduction shifts to the next financial year
31 July	File your ITR (ITR-1 / ITR-2, non-audit cases)	Late fee under Section 234F plus interest under Section 234A

One point salaried employees often get wrong: the declaration you give your employer in April is not binding at filing time. If you told HR "new regime" and later find the old regime suits you better, you can still switch when you file — provided you file by the due date. Filing on time is what protects that option.

Costly Mistakes Under the Default New Regime

1. Buying tax-saving products while on the new regime. ELSS, tax-saver FDs and PPF top-ups bought in March give you nothing under 115BAC. Buy them because they fit your goals, not for a deduction you cannot claim.
2. Never asking about employer NPS. The 14% 80CCD(2) deduction is the largest break still available to a new-regime employee, and it goes unused simply because nobody raises it with HR.
3. Treating the regime choice as permanent. A year in which you take a home loan or start paying big-city rent deserves a fresh comparison.
4. Buying insurance as a tax product. Endowment policies typically return 4–5% and lock you in for decades. Under the new regime there is not even a deduction to justify the trade-off.
5. Ignoring the Annual Information Statement. Reconcile your AIS and Form 26AS against Form 16 before filing; mismatches are the leading cause of notices for salaried filers.
6. Assuming nil tax means no return. If gross total income before the 87A rebate exceeds the basic exemption limit, you must still file — and filing is how you reclaim excess TDS.

Frequently Asked Questions

Is income up to ₹12 lakh really tax-free in FY 2025-26?

Under the new regime, yes, for a resident whose total income does not exceed ₹12 lakh — the ₹60,000 rebate under Section 87A cancels the ₹60,000 of slab tax. The ₹75,000 standard deduction lifts that to a salary of ₹12.75 lakh. The rebate does not apply to income taxed at special rates, such as capital gains under Section 112A.

Can I switch between the old and new tax regime every year?

A salaried individual with no business income can choose afresh each year, including at the time of filing. The April declaration to your employer only governs TDS; the final choice is made in your ITR, provided it is filed by the due date. Taxpayers with business income face a once-only switch back.

Which deductions survive under the new tax regime?

The ₹75,000 standard deduction, employer NPS up to 14% of basic plus DA under Section 80CCD(2), employer EPF within limits, gratuity, leave encashment, the family pension deduction, and a narrow set of official-duty allowances under Section 10(14). HRA, LTA, 80C, 80D, 80CCD(1B) and Section 24(b) interest on a self-occupied property are not available.

How much in deductions do I need before the old regime is worth it?

Far more than the ₹3–4 lakh figure older articles quote. On a ₹15 lakh salary you need roughly ₹5.9 lakh of total deductions, including the ₹50,000 standard deduction, just to break even — which in practice means a substantial HRA claim or home loan interest on top of a fully used 80C.

Do I still have to file an ITR if my employer deducted the correct TDS?

Yes, if gross total income before deductions and the 87A rebate exceeds the basic exemption limit. Form 16 is not a return. Filing also lets you reclaim excess TDS, carry forward capital losses, and choose the regime that suits you.
