Difference Between Old and New Tax Regime

Your income bracket establishes the amount of taxes payable each financial year at the time of filing the annual income tax returns. The Income Tax Act, 2025, contains provisions to reduce the Indian taxpayers’ tax liability through multiple deductions and exemptions. To simplify the taxation system in India, a new tax regime was introduced in 2020.

The major differences between the old and the new tax regime are in the income tax slab rates and the ability to secure concessions and rebates. Taxpayers should understand the differences between the old and new tax regimes so they may opt for the right tax structure and plan their taxation accordingly.

Understanding the Old Tax Regime

The old tax regime allows taxpayers to enjoy several exemptions and deductions aimed at reducing their taxable income. It exempts income up to Rs.2.5 Lakh, while the maximum rate applies on income above Rs.10 Lakh at 30%.

Tax Rates Under the Old Tax Regime  

The old tax slabs remain unchanged for Tax Year 2026-27 as follows:  

Deductions and Exemptions Under the Old Tax Regime

The old tax structure extends the following exemptions:

• House Rent Allowance (HRA)
• Leave Travel Allowance (LTA)
• Deductions available under Section 153 on interest incurred through savings account deposits.
• Senior citizens can claim a deduction up to Rs.50,000 on interest incurred through savings account deposits
• Standard deduction of Rs.50,000 for all salaried individuals
• Entertainment allowance and professional tax deduction in case of government employees
• Deduction of Rs.15,000 permitted from the family pension under Section 93(1)(d)
• Tax concession on Home Loan interest paid for a self-occupied or vacant property under Section 22
• Rs.50,000 for contribution to the National Pension System (NPS) under Section 124
• Rebate in health insurance premium for self, spouse, children, and parents under Section 126
• Exemption of income up to Rs.1.5 lakh under Section 123 read with Schedule XV

Deductions under Section 123, read with Schedule XV, can be received for the following instruments:

• Pension funds such as EPF and PPF
• ELSS, ULIP, and tax-saving fixed deposits
• Saving schemes like the National Savings Certificate, Sukanya Samriddhi Yojana, Senior Citizens’ Savings Scheme
• Life insurance premium
• Home Loan principal repayment
• Children’s tuition fees

Advantages and Disadvantages of the Old Tax Regime

The old tax regime accords the following advantages and disadvantages:

Advantages

• The old tax rules extend ample tax-saving deductions and exemptions thereby lowering the volume of payable taxes. These concessions also fetch zero liability taxes for certain income slabs

• In order to secure the benefits of the Income Tax Act provisions, the tax-saving guidelines result in significant savings through suitable financial instruments

Disadvantages

• The old regime holds higher tax rates and involves more paperwork

• Funds need to be locked in for a specific duration in prescribed instruments for tax exemptions, limiting investment opportunities for individuals

Understanding the New Tax Regime

The new regime is now the default tax system. However, you can still opt for the old tax regime. The revised rules are aimed at easing the taxation process and avoiding any confusion that may arise from a multitude of provisions, which is why it offers few exemptions to render tax compliance less tedious.

Tax Rates Under the New Tax Regime

The new regime comprises six tax slabs wherein the basic exemption limit has been raised to Rs.4 Lakh. Furthermore, the tax rebate earned under Section 157 applies to earnings up to Rs.12 Lakh. 

Calculation of Taxes Under the New Tax Regime 

The new system levies income tax in gradational slabs. This means that if you earn a salary of Rs.10 Lakh p.a., you will not be charged a flat 10% rate on your income as indicated in the table above. Instead, the tax will be calculated in stages such as: 

• First, income up to Rs.4 Lakh will be considered which attracts no tax  
• Next, the income between Rs.4 Lakh to Rs.8 Lakh will be charged 5%; so 5% of Rs.4 Lakh = Rs.20,000  
• Then, the income slab of Rs.8 Lakh to Rs.12 Lakh will be levied 10% tax, which comes to Rs.20,000  
• This will bring the total tax outgo to Rs.40,000. 

Changes in Deductions and Exemptions Under the New Tax Regime

Taxpayers opting for the new system may enjoy lower tax slabs, but they cannot receive the exemptions and deductions extended by the old regime. Still, they may gain a few concessions like:

• Interest on savings accounts up to Rs.3,500 under Schedule II (Table: S. No. 11)
• Income from agriculture
• Standard deduction on rent
• Retrenchment compensation
• Income from life insurance maturity under Schedule II (Table: S. No. 2)
• Scholarship money for education
• Death and retirement benefits
• Employer contribution to NPS and EPF up to 12% of salary; interest on EPF up to 9.5% p.a.
• Voluntary retirement scheme proceeds up to Rs.5 Lakh
• Gratuity up to Rs.20 Lakh
• Leave encashment on retirement
• The interest and maturity amount of PPF or Sukanya Samriddhi Yojana
• Commutation of pension

Benefits and Demerits of the New Tax Regime

Some of the advantages of the new tax regime are:

• The new plan provides concessional rates, leaving them with more disposable income
• Fewer documentation requirements as one needs to forego additional tax deductions
• Taxpayers may opt for investments as per their preference instead of picking options simply meant as tax-saving measures
• Tax calculation is much easier and quicker

Some of the disadvantages of the new system include:

• It does not permit rebates that lower tax liability
• Taxpayers may not be inclined to save or invest extensively in ELSS, PPF, etc., as there is no tax relief attached

Difference Between the Old Tax Regime and the New Tax Regime

The new regime allows a standard deduction of Rs.75,000 for all salaried persons and a deduction for family pension, which may be Rs.25,000 or 1/3rd of the pension. At the same time, those who stand to claim a higher amount of exemptions must continue with the old regime.

Which Tax Regime is More Beneficial for Taxpayers?

The choice between tax regimes depends on the taxpayer's investment decisions, tax-saving strategies, and financial objectives. Those with substantial deductions and tax-saving investments may prefer the old tax regime, while individuals with fewer deductions might benefit more from the new regime's rates. It is advisable to use an income tax calculator before making a decision.

Impact of the New Tax Regime on Different Income Groups

The new system aims to reduce the taxation obligation for all income groups by almost half. It may prove advantageous for individuals with an annual salary up to Rs.12 Lakh or those drawing higher salaries. If your income is below Rs.12 Lakh, opting for the new tax regime can help you save more tax. But if your earnings exceed Rs.12 Lakh, the old regime will be beneficial because you will have more deductions.

How to Choose Between the Old and New Tax Regimes

If you are eligible to claim deductions or exemptions under the old tax regime towards HRA, LTA, PPF, etc., you may choose to stay with the existing tax scheme. Likewise, individuals who hold money in tax-saving instruments and other stipulated investments may maximise tax relief under the old regime.

For example, housing loan borrowers repaying their EMIs can receive substantial Home Loan tax benefits. If you aspire to avail a Home Loan, you may secure tax relief on both the Home Loan interest and principal components. Therefore, it is vital to secure lower Home Loan interest rates from your lender to maintain a reasonable cost of credit.

Factors to Consider While Choosing Between Old Tax Regime and New Tax Regime

You can choose a tax regime based on your income levels and investment portfolio. Here are the basic parameters taxpayers need to keep in mind:

• Your income level
• Investment goals for the present and the future
• Tax-saving potential
• Your tax liability under both regimes
• Future tax implications under both tax structures

How to Compute Your Taxes Correctly

Calculating taxes entails a considerable amount of number crunching, which may run the risk of errors. Hence, taxpayers can benefit from the use of an Income Tax Calculator. This tool enables you to compute Home Loan tax benefits accurately.

Can You Switch Between the New and Old Tax Regimes Every Year? 

Yes, you can switch between tax regimes, but it depends on whether you have business/professional income or not. 

• If you’re an individual, HUF, or AOP, etc., with only non-business income such as salary, interest, or pension, you can switch between the new tax regime and the old tax regime each year. 
• If you’re an individual, HUF, or AOP, etc., with business or professional income, and you have opted out of the new regime (that is, chosen the old regime), then you will have only one chance to switch back to the new tax regime thereafter. Once you switch back to the new regime, you cannot revert to the old regime in future years. 

Conclusion

Taxpayers can opt for the old or new tax regime. However, it is important to understand the exemptions available under both regimes. After carefully exploring the possible implications on your taxes payable for the year, you can choose the regime that meets your financial goals.
