Income Tax Slab for FY 2024-25 WealthSure: Old vs New Regime

Income Tax Slab for FY 2024-25: New Tax Regime

The new tax regime for FY 2024-25 offers a simplified slab structure with lower rates and fewer deductions. It is often useful for taxpayers who do not claim many exemptions or deductions, but every taxpayer should compare it with the old regime before filing.

Health and education cess at 4% is added to the tax amount after applying the slab rates and rebate rules. Surcharge may apply for very high-income taxpayers. For salaried taxpayers, the standard deduction available under the new regime for FY 2024-25 can materially affect taxable income, so compare based on taxable income rather than gross salary alone.

Old Tax Regime Slabs for FY 2024-25

The old tax regime for FY 2024-25 keeps the traditional slab structure and allows many deductions and exemptions. It may benefit taxpayers who can claim a meaningful amount through HRA, Section 80C, Section 80D, home-loan interest, NPS and other eligible items.

For many salaried people, the old regime becomes attractive only after adding the real value of deductions and exemptions. The mistake is to compare slab rates without adjusting taxable income. A person earning Rs 12 lakh with high eligible deductions may pay less under the old regime, while another person with the same salary and limited deductions may prefer the new regime.

How to Choose Between Old and New Tax Regime for FY 2024-25

The right regime is the one that gives a lower lawful tax liability after considering your actual income, deductions and exemptions. Do not choose the regime only because it looks simpler or because a colleague selected it.

For a document-based comparison, collect Form 16, salary breakup, rent proofs, home-loan interest certificate, insurance premium receipts, tuition fee receipts, health insurance proof, donation receipts and investment statements. WealthSure’s tax optimizer service and tax-saving suggestions can help taxpayers understand the practical impact of these details without treating tax saving as a guesswork exercise.

Assessment Year vs Financial Year: What to Use for FY 2024-25

FY 2024-25 is the year in which income is earned, and AY 2025-26 is the year in which that income is assessed and the return is filed. This is one of the most common sources of confusion for first-time filers.

If you earned salary, interest, freelance income, rent or capital gains between 1 April 2024 and 31 March 2025, that income belongs to Financial Year 2024-25. The income tax return for this period is filed for Assessment Year 2025-26. When using ITR utilities, challan records, tax payment history or advisory documents, always check whether the field asks for FY or AY.

Using the wrong assessment year can create payment-matching issues, return filing errors or confusion while checking tax payment history. If your return involves late payment, self-assessment tax, revised return or updated return, consider expert review through revised and updated return filing support.

Standard Deduction, Section 87A Rebate and Cess

Standard deduction and Section 87A rebate can change your final tax payable even when the slab table looks straightforward. This is why a tax slab chart should be read together with your income type and regime selection.

Standard deduction for salary and pension income

For eligible salary income in FY 2024-25, the standard deduction is available under both regimes, but the amount differs. The new regime allows a higher standard deduction of Rs 75,000 for eligible salaried taxpayers, while the old regime allows Rs 50,000. Pensioners should review the applicable treatment based on pension type and documents.

Section 87A rebate

Section 87A rebate is available to eligible resident individuals when taxable income is within the prescribed threshold. Under the new regime for FY 2024-25, the commonly relevant threshold is up to Rs 7 lakh taxable income. Under the old regime, the threshold is generally up to Rs 5 lakh taxable income. This can reduce tax payable to nil in eligible cases, but it should not be confused with exemption of all income in all cases.

Health and education cess

After slab tax and surcharge, if any, health and education cess at 4% applies. Tax calculation examples should therefore include cess unless the final tax after rebate is nil.

Income Tax Calculation Examples for FY 2024-25

Examples make slab rates easier to understand because income tax is calculated progressively. Each slab rate applies only to the income falling in that slab, not to the entire income.

Example 1: Salaried employee with limited deductions

Rohit has gross salary of Rs 9,00,000 in FY 2024-25 and limited deductions. Under the new regime, after eligible standard deduction, his taxable income may reduce. The slab calculation would apply nil, 5% and 10% layers, and Section 87A may not apply once taxable income exceeds the eligible threshold. Under the old regime, if he has only small deductions, the higher slab structure may result in more tax. His best approach is to compare both regimes using actual Form 16 data and not rely only on gross salary.

Example 2: Salaried employee with HRA, 80C and health insurance

Meera earns Rs 12,00,000 and pays rent in Mumbai. She also has provident fund, life insurance premium and health insurance premium. Her common mistake would be assuming the new regime is automatically better because rates are lower. The correct approach is to calculate the old regime after HRA exemption, Section 80C, Section 80D and standard deduction, then compare it with the new regime after eligible standard deduction. WealthSure’s assisted filing support can help in document-based comparison.

Example 3: Freelancer with advance tax requirement

Arjun is a freelance designer with receipts from multiple clients and no Form 16. His income tax slab depends on net taxable income after allowable expenses and deductions, but he may also need to consider advance tax if tax liability crosses the relevant threshold. The mistake is to wait until ITR filing and then discover interest under Sections 234B or 234C. The better approach is to estimate income during the year and use advance tax calculation support where required.

Example 4: Investor with salary and capital gains

Nisha has salary income and also sold equity mutual funds. Her salary may follow the normal slab system, but capital gains may have special tax rates depending on holding period and asset type. The mistake is to add every gain into the normal slab table without checking the capital gains provisions. A correct filing approach separates salary, interest, short-term gains, long-term gains and exempt income, then calculates tax under the applicable rules. For such cases, WealthSure’s capital gains tax review can help reduce reporting errors.

Details to Check Before Filing AY 2025-26 Return

Before filing, check your income, deductions, tax payments and regime selection together. A clean tax slab calculation is only useful when the underlying data is accurate.

• Confirm that income belongs to FY 2024-25 and the return is for AY 2025-26.
• Check Form 16, salary slips and employer-reported taxable salary.
• Review bank interest, FD interest, dividend income and other income.
• Download and compare AIS, TIS and Form 26AS where relevant.
• Calculate tax under old and new regimes before selecting the final regime.
• Keep proof for deductions and exemptions claimed under the old regime.
• Check advance tax and self-assessment tax payments before submission.
• Review capital gains reports from brokers or mutual fund platforms.
• Do not ignore foreign income, NRI status or foreign assets where applicable.

Common Mistakes to Avoid While Using FY 2024-25 Slabs
