Best tax-saving investments FY 2026-27 — old vs new regime comparison

Introduction

Choosing the right tax-saving investment strategy for FY 2026-27 requires first deciding whether the old tax regime or new tax regime is more beneficial.

For FY 2026-27, the new tax regime continues to be the default regime, and its slab structure is significantly more favourable for many taxpayers with moderate deductions. At the same time, taxpayers with substantial deductions and exemptions—such as HRA, home-loan interest, Section 80C investments, health-insurance premiums and NPS contributions—may still find the old regime beneficial.

The Income Tax Department’s current guidance confirms that under the new regime, tax rates for individuals start at nil up to ₹4 lakh and progress through 5%, 10%, 15%, 20%, 25% and 30% slabs. The Section 87A rebate has also been increased so that eligible taxpayers with total income up to ₹12 lakh can potentially have zero tax on ordinary slab-rate income.

Therefore, tax-saving investment decisions for FY 2026-27 should not be based simply on the question “Which investment gives the biggest deduction?” Instead, taxpayers should first determine which regime produces the lower overall tax liability.

🆕 Important FY 2026-27 Development

FY 2026-27 is also the first financial year governed by the Income-tax Act, 2025 for the new tax year beginning 1 April 2026.

The Income Tax Department has introduced an online tax estimator that specifically allows taxpayers to compare tax under the old and new regimes for the relevant period.

For practical tax planning, the fundamental distinction remains:

Old Regime

Higher tax rates, but access to a much wider range of deductions and exemptions.

New Regime

Lower/restructured slab rates, but most traditional deductions and exemptions are not available.

Old vs New Tax Regime — FY 2026-27

For an individual below 60 years of age, the broad slab structure is:

Taxable Income	Old Regime	New Regime
Up to ₹2.5 lakh	Nil	Nil up to ₹4 lakh
₹2.5–₹5 lakh	5%	5% on ₹4–8 lakh
₹5–₹10 lakh	20%	10% on ₹8–12 lakh
Above ₹10 lakh	30%	15% on ₹12–16 lakh
—	—	20% on ₹16–20 lakh
—	—	25% on ₹20–24 lakh
—	—	30% above ₹24 lakh

These rates are before applicable surcharge and 4% Health & Education Cess.

Section 87A Rebate — Major Advantage of the New Regime

One of the biggest reasons the new regime can be attractive in FY 2026-27 is the enhanced Section 87A rebate.

For eligible resident individuals under the new regime, the rebate can be up to ₹60,000 where total income does not exceed ₹12 lakh, subject to the statutory conditions.

This means that an individual with ordinary taxable income up to ₹12 lakh may effectively have zero income tax after the applicable rebate.

For salaried taxpayers, the ₹75,000 standard deduction can make the effective salary level for this zero-tax outcome as high as ₹12.75 lakh, assuming the income consists of eligible salary income and other conditions are satisfied.

Important

The rebate is not a blanket exemption for every type of income. Certain special-rate incomes, such as specified capital gains, are subject to separate rules.

Best Tax-Saving Investments Under the Old Regime

The old regime remains attractive for taxpayers who actively use deductions and exemptions.

Public Provident Fund — PPF

PPF is one of the most popular traditional tax-saving investments.

Investment under PPF can qualify for deduction under Section 80C, subject to the overall limit.

Maximum 80C deduction

₹1.5 lakh

PPF is particularly attractive for taxpayers looking for:

Long-term savings

Government-backed investment

Tax-efficient accumulation

Retirement planning

However, PPF has a long investment horizon and withdrawal restrictions.

Employee Provident Fund — EPF

For salaried employees, employee contributions to EPF can qualify under the Section 80C framework, subject to the applicable conditions and overall limit.

Therefore, employees should not automatically invest an additional ₹1.5 lakh under other instruments without first checking how much of their 80C limit is already being utilised by:

EPF

Life insurance

Home-loan principal

Tuition fees

Other eligible investments

ELSS Mutual Funds

Equity Linked Savings Scheme (ELSS) is a tax-saving mutual fund category eligible for Section 80C deduction.

Advantages include:

Equity market exposure

Tax deduction under old regime

Three-year statutory lock-in

Potential long-term capital appreciation

However, ELSS carries market risk and should not be selected solely for the tax deduction.

Life Insurance Premium

Eligible life-insurance premiums can qualify for Section 80C deduction, subject to the applicable conditions.

Taxpayers should not purchase unnecessary insurance simply to save tax.

A better strategy is to determine the required life cover first and then consider the tax benefit as an additional advantage.

National Savings Certificate — NSC

NSC is another traditional Section 80C investment.

It can be suitable for taxpayers seeking a relatively conservative fixed-income investment.

The interest treatment and reinvestment rules should be considered when calculating the overall tax benefit.

Tax-Saving Fixed Deposits

Certain bank fixed deposits with the prescribed lock-in period qualify under Section 80C.

These can appeal to conservative investors who prefer fixed returns over equity-market exposure.

However, the interest earned is generally taxable under the applicable provisions.

Therefore, taxpayers should compare the post-tax return, rather than looking only at the stated interest rate.

Sukanya Samriddhi Account

Eligible contributions to Sukanya Samriddhi Account can qualify under Section 80C.

It is designed specifically for eligible girl children and has a long-term savings objective.

It can be particularly useful for parents planning for:

Higher education

Marriage expenses

Long-term financial security

Home-Loan Principal

Repayment of the principal portion of a qualifying housing loan can fall within the Section 80C deduction framework, subject to the prescribed conditions and overall ₹1.5 lakh limit.

This means a taxpayer paying:

EPF ₹70,000

Home-loan principal ₹50,000

ELSS ₹30,000

has already utilised the full ₹1.5 lakh 80C limit.

Additional ELSS investment would not create another 80C deduction.

9. Health Insurance — Section 80D

Health-insurance premiums can provide an additional deduction under Section 80D under the old regime, subject to age, coverage and statutory limits.

This is separate from the ₹1.5 lakh Section 80C limit.

Potential deductions can relate to:

Self

Spouse

Dependent children

Parents

Higher limits can apply for senior-citizen parents, subject to the law.

This makes health insurance particularly valuable because it provides both:

Financial protection + tax benefit

10. NPS — Section 80CCD(1B)

The National Pension System can provide an additional deduction of up to:

₹50,000

under Section 80CCD(1B), subject to eligibility.

This deduction is particularly useful because it is over and above the ₹1.5 lakh Section 80C limit.

For taxpayers in higher tax brackets, NPS can therefore be an important retirement-planning and tax-saving instrument under the old regime.

11. Home-Loan Interest — Section 24(b)

For a qualifying self-occupied residential property, interest on a housing loan can generally qualify for deduction subject to the prescribed conditions and limits.

A commonly applicable limit for self-occupied property is:

₹2 lakh

subject to the statutory conditions.

This deduction can substantially affect the old-versus-new regime calculation for homeowners.

12. HRA Exemption

House Rent Allowance is not technically an investment, but it can be one of the most valuable tax benefits under the old regime for eligible salaried employees.

The exemption depends on factors including:

Actual HRA received

Salary

Rent paid

Location of residence

Other prescribed conditions

The new regime generally does not provide the traditional HRA exemption.

Therefore, employees paying substantial rent should compare both regimes carefully.

13. Education Loan Interest — Section 80E

Interest paid on an eligible education loan can qualify for deduction under Section 80E under the old regime, subject to the statutory conditions.

The deduction relates to interest, rather than the principal repayment.

There is generally no separate monetary ceiling on the qualifying interest deduction, but the deduction is available only for the prescribed period and qualifying loans.

14. Section 80U and Other Specified Deductions

The old regime also provides access to certain deductions for eligible taxpayers, including specified deductions relating to disability and other circumstances.

These benefits can make the old regime more attractive for taxpayers with substantial eligible deductions.

Which Investments Are Available Under the New Regime?

This is where taxpayers often make mistakes.

The new regime does not mean that you cannot invest in PPF, ELSS, NPS or insurance.

You can still make those investments.

The difference is:

You may not receive the same tax deduction for those investments under the new regime.

For example, a taxpayer can invest ₹1.5 lakh in PPF under the new regime, but the investment does not automatically generate the traditional Section 80C deduction available under the old regime.

Therefore, investment choice and tax-regime choice are two separate decisions.

Important Tax Benefits Still Relevant Under New Regime

Although most traditional deductions are restricted, certain benefits remain available.

Standard Deduction

For salaried individuals, the standard deduction under the new regime is:

₹75,000

The Income Tax Department’s FY 2026-27 guidance reflects this enhanced standard deduction framework.

Employer NPS Contribution

Employer contribution to NPS under Section 80CCD(2) continues to be an important tax-efficient benefit under the new regime, subject to the applicable statutory limits.

This is especially useful for salaried employees whose employers offer NPS as part of their compensation structure.

Instead of relying exclusively on personal investments for tax saving, employees can discuss an appropriately structured salary package with their employer.

Why New-Regime Tax Planning Is Different

Under the old regime, taxpayers often think:

“How much can I invest to claim deductions?”

Under the new regime, the better question is:

“How can I structure my salary and finances efficiently while taking advantage of the lower slab rates and permitted benefits?”

This is an important shift in tax planning.

🆚 Old vs New Regime — Investment Comparison

Investment / Benefit	Old Regime	New Regime

PPF	✅ 80C	❌ No 80C deduction
ELSS	✅ 80C	❌ No 80C deduction
Life Insurance	✅ 80C, subject to conditions	❌ Generally unavailable
NSC	✅ 80C	❌ No 80C deduction
Tax-saving FD	✅ 80C	❌ No 80C deduction
EPF employee contribution	✅ 80C	❌ No 80C deduction
Home-loan principal	✅ 80C	❌ Generally unavailable
Health Insurance	✅ 80D	❌ Generally unavailable
NPS self-contribution — 80CCD(1B)	✅	❌
Employer NPS — 80CCD(2)	✅	✅ Subject to limits
HRA exemption	✅	❌
Home-loan interest — self-occupied	✅ Subject to conditions	❌ Generally unavailable
Education-loan interest	✅ 80E	❌
Standard deduction for salary	₹50,000	₹75,000
87A rebate	Available subject to old-regime limits	Up to ₹60,000 for eligible income up to ₹12 lakh

Example 1 — Taxpayer With Few Deductions

Suppose a salaried employee has:

Gross salary: ₹12 lakh

Assume the employee has very few deductions.

Under the new regime, the ₹75,000 standard deduction can reduce taxable salary to ₹11.25 lakh. This is within the ₹12 lakh rebate threshold, subject to the applicable conditions.

The taxpayer may therefore have zero tax liability after the applicable Section 87A rebate.

In such a situation, investing ₹1.5 lakh in ELSS solely to obtain an 80C deduction would not provide the same tax advantage under the new regime.

Example 2 — Taxpayer With Large Deductions

Consider a taxpayer earning:

₹20 lakh

and having substantial eligible old-regime benefits:

80C investments: ₹1.5 lakh

NPS: ₹50,000

Health insurance: ₹50,000

Home-loan interest: ₹2 lakh

HRA exemption: substantial amount

The taxpayer’s total deductions/exemptions can materially reduce taxable income under the old regime.

In such a situation, the old regime may become competitive despite its higher slab rates.

The correct answer depends on the taxpayer’s exact salary, exemptions, deductions and other income.

Tax-Saving Investment Strategy by Income Level

Income Up to ₹12 Lakh

For many taxpayers with ordinary income and no significant special-rate income, the new regime deserves serious consideration first because of the enhanced Section 87A rebate.

Tax-saving investments should primarily be selected based on financial goals rather than solely for tax deductions.

Income ₹12–₹20 Lakh

This is a zone where the comparison becomes more individualised.

Consider:

HRA

80C investments

80D

NPS

Home-loan interest

Education-loan interest

Employer NPS

Other eligible deductions

A tax calculation under both regimes is advisable.

Income Above ₹20 Lakh

Higher-income taxpayers with substantial deductions should calculate both regimes carefully.

The old regime may become beneficial where the taxpayer has:

Large HRA exemption

Significant home-loan interest

Maximum 80C utilisation

NPS contribution

Health-insurance deductions

Education-loan interest

Other eligible deductions

However, the new regime’s lower slab structure can still make it attractive.

Don’t Invest Just to Save Tax

Tax planning should never be the sole reason for making an investment.

For example:

Bad approach

“I need ₹1.5 lakh deduction, so I will invest ₹1.5 lakh in ELSS.”

Better approach

“I need equity exposure for long-term wealth creation, and ELSS can provide that while also giving an eligible deduction under the old regime.”

Similarly, don’t buy unnecessary insurance simply because it offers a tax deduction.

Best Investment Strategy for Old-Regime Taxpayers

A balanced strategy can include:

For Short/Medium-Term Safety

Tax-saving FD

NSC

For Long-Term Retirement

PPF

NPS

EPF

For Equity Growth

ELSS

For Family Protection

Term insurance

For Medical Protection

Health insurance

The optimal combination depends on age, income, risk appetite, liquidity needs and financial goals.

Best Strategy for New-Regime Taxpayers

Under the new regime, investment decisions should focus more heavily on:

Retirement planning

Asset allocation

Emergency funds

Equity investments

Debt investments

Insurance protection

Employer NPS

Long-term wealth creation

Instead of investing ₹1.5 lakh merely to use Section 80C, a taxpayer can choose investments based on expected returns, liquidity and risk profile.

Common Tax-Planning Mistakes in FY 2026-27

Assuming Old Regime Is Always Better Because of Deductions

Lower slab rates under the new regime can outweigh deductions.

Assuming New Regime Means No Tax Planning

Salary structuring, employer NPS and investment planning remain important.

Investing ₹1.5 Lakh in ELSS Without Checking the Regime

The Section 80C deduction is relevant to the old regime.

Ignoring Employer NPS

Employer NPS contribution can remain valuable under the new regime.

Ignoring HRA

For eligible salaried employees paying substantial rent, HRA can significantly change the comparison.

Looking Only at Tax Saving

An investment should make financial sense even without the tax benefit.

FY 2026-27 Tax-Saving Checklist

Before making tax-saving investments, calculate:

Annual taxable salary

Standard deduction

HRA exemption

Existing EPF contribution

Home-loan principal

Home-loan interest

Life-insurance premium

PPF contribution

ELSS investment

Health-insurance premium

NPS contribution

Employer NPS contribution

Education-loan interest

Other eligible deductions

Capital gains/special-rate income

Tax under old regime

Tax under new regime

Then choose the regime that produces the better overall result.

Conclusion

For FY 2026-27, the new tax regime should be the starting point for comparison, particularly for taxpayers with relatively few deductions. Its revised slab structure and enhanced Section 87A rebate can result in substantially lower tax for many individuals. The Income Tax Department confirms that eligible individuals with total income up to ₹12 lakh can receive a rebate of up to ₹60,000 under the new regime, subject to the applicable conditions.

However, the old tax regime remains relevant for taxpayers with substantial deductions and exemptions. Individuals making significant use of Section 80C, 80D, 80CCD(1B), HRA, home-loan interest and education-loan interest should calculate their tax liability under both regimes before making a final decision.

The key point is that tax-saving investment and tax-regime selection are not the same thing. A person can continue investing in PPF, ELSS, NPS, insurance or other financial products under the new regime; the question is whether those investments provide a tax deduction under that regime.

For FY 2026-27, the most effective approach is therefore to first calculate the tax liability under both regimes and then invest according to financial objectives, risk appetite, liquidity requirements and retirement goals. The Income Tax Department itself provides a tax estimator designed to compare the old and new regimes, including calculations under the Income-tax Act, 2025 for Tax Year 2026-27.
