  • Salary and wages 

  • Professional fees 

  • Rental income 

  • Interest income 

  • Dividends 

  • Capital gains from investments 

The tax rate depends on income slabs announced by the government. 

Corporate Income Tax 

Companies pay tax on profits after accounting for eligible expenses and deductions. Corporate tax rates differ based on factors such as company type, turnover and applicable tax rules. 

Capital Gains Tax 

Capital gains tax applies when a taxpayer earns profits by selling assets such as: 

  • Shares 

  • Mutual funds 

  • Real estate 

  • Gold 

  • Other investments 

Capital gains are classified as: 

Type 

Holding period and taxation 

Short-term capital gains 

Applicable when assets are sold within a shorter holding period 

Long-term capital gains 

Applicable when assets are held beyond the specified period 

How Is Income Tax Calculated? 

Income tax calculation involves identifying total income, reducing eligible deductions and applying the applicable tax rates. 

Income Tax Calculation Formula 

Taxable Income = Gross Total Income – Eligible Deductions 

Where: 

  • Gross Total Income: Total income earned from salary, business, investments and other sources. 

  • Eligible Deductions: Amounts allowed under sections such as 80C, 80D and others. 

  • Taxable Income: Income on which tax is calculated. 

Example: 

Suppose: 

  • Salary income = ₹12,00,000 

  • Interest income = ₹50,000 

  • Eligible deductions = ₹1,50,000 

Calculation: 

Gross Total Income = ₹12,00,000 + ₹50,000 

Gross Total Income = ₹12,50,000 

Taxable Income = ₹12,50,000 – ₹1,50,000 

Taxable Income = ₹11,00,000 

The applicable tax slab rates are then applied to ₹11,00,000. 

What Are the Income Tax Slabs in India? 

The government provides different tax slabs under the old and new tax regimes.  

The new tax regime has become the default regime, offering lower tax rates but fewer deductions. The old tax regime allows taxpayers to claim several exemptions and deductions.  

Taxpayers should compare both options before filing their returns.

Capital Gains Tax 

Capital gains tax applies when a taxpayer earns profits by selling assets such as: 

  • Shares 

  • Mutual funds  

  • Real estate 

  • Gold 

  • Other investments  

Capital gains are classified as: 

Type 

Holding period and taxation 

Short-term capital gains (STCG) 

Applicable when assets are sold within a shorter holding period. For listed equities and equity-oriented mutual funds, STCG is taxed at a flat rate of 20%. For other assets, gains are taxed at normal slab rates. 

Long-term capital gains (LTCG) 

Applicable when assets are held beyond the specified period (e.g., >12 months for listed equities/equity mutual funds). LTCG on eligible equity assets exceeding ₹1.25 lakh in a financial year is taxed at a flat rate of 12.5% without indexation benefits. 

Which Income Tax Deductions Can Help Reduce Tax Liability? 

Tax deductions reduce taxable income and help taxpayers legally lower their tax burden. 

Common deductions include: 

Section 80C Deductions 

Taxpayers can claim deductions for investments such as: 

  • Public Provident Fund (PPF) 

  • Employee Provident Fund (EPF) 

  • Equity Linked Savings Scheme (ELSS) 

  • Life insurance premiums 

  • National Savings Certificate (NSC) 

The maximum deduction available under Section 80C is ₹1.5 lakh per financial year. 

Health Insurance Deduction under Section 80D 

Premiums paid towards health insurance policies may qualify for deductions under Section 80D, subject to applicable limits. 

Home Loan Benefits 

Taxpayers can claim benefits on: 

  • Principal repayment under Section 80C 

  • Interest payment under Section 24(b) 

These deductions can make home ownership more tax-efficient.

Step 1: Collect Required Documents 

Keep documents such as: 

  • PAN card 

  • Aadhaar details 

  • Form 16 

  • Bank statements 

  • Investment proofs 

  • Capital gains statements

Step 3: Select the Appropriate ITR Form 

Choose the correct Income Tax Return form based on your income sources. 

Step 4: Verify Income Details 

Check details available through the Annual Information Statement (AIS) and Form 26AS. 

Step 5: Submit and Verify Return 

After filing, complete verification through available electronic methods. 

What Is Advance Tax and Who Needs to Pay It? 

Advance tax is a system where taxpayers pay income tax in instalments during the financial year instead of paying the entire amount after year-end. 

It generally applies when estimated tax liability exceeds ₹10,000 in a financial year. 

Advance tax instalments are usually paid on: 

  • June 15 

  • September 15 

  • December 15 

  • March 15 

Failure to pay advance tax on time may attract interest charges. 

Tax Refund vs Tax Exemption 

Tax refund and tax exemption are two different concepts that help taxpayers manage their tax liability. A tax refund is the amount returned by the Income Tax Department when the tax paid or deducted (such as TDS) is higher than the actual tax payable. Taxpayers can claim a refund by filing their income tax return within the specified deadline. 

A tax exemption, on the other hand, reduces the portion of income on which tax is calculated. It allows certain incomes or expenses to be excluded from taxable income.  

For example, salaried employees can claim exemption on a part of their House Rent Allowance (HRA) if they meet the required conditions, thereby lowering their taxable income. 

How Can You Plan Your Taxes Effectively? 

Effective tax planning focuses on reducing tax liability through legal methods. 

Some useful strategies include: 

  • Start investments early instead of making last-minute decisions. 

  • Compare old and new tax regimes before choosing one. 

  • Maintain records of all deductions and investments. 

  • Review salary structure and available exemptions. 

  • Diversify investments based on financial goals. 

Tax planning should focus on overall financial growth, not just saving taxes. 

Consequences of Tax Evasion 

Tax evasion refers to illegally avoiding tax payments by hiding income, submitting false information or manipulating records. 

Possible consequences include: 

  • Interest charges on unpaid taxes 

  • Financial penalties 

  • Prosecution in serious cases 

  • Increased scrutiny from tax authorities 

Taxpayers should use legal tax-saving options instead of attempting illegal methods. 

Conclusion 

Income tax is an essential part of financial planning. While the process may seem complicated at first, understanding income sources, deductions, tax regimes, and filing procedures can make compliance easier. A well-planned approach helps taxpayers reduce their tax burden legally while ensuring they meet government requirements. Regular financial planning, accurate record-keeping, and timely filing are key to managing income tax efficiently.
