⚠️ Urgent Reminder: The final installment (Q4) of advance tax for FY 2025-26 is due on March 15, 2026. Missing this deadline attracts interest penalties under Section 234B and 234C of the Income Tax Act.

What is Advance Tax?

Advance tax, often called "pay-as-you-earn" tax, is the income tax you pay in advance throughout the financial year rather than as a lump sum at the time of filing your Income Tax Return (ITR). The Income Tax Department mandates that taxpayers estimate their annual tax liability and pay it in quarterly installments.

This system ensures a steady flow of revenue for the government and prevents taxpayers from facing a massive tax burden all at once. For the Financial Year 2025-26 (Assessment Year 2026-27), understanding advance tax compliance is crucial, especially with the new tax regime changes announced in the Union Budget 2025.

Who Must Pay Advance Tax?

You are required to pay advance tax if your estimated tax liability for the financial year exceeds ₹10,000 after accounting for TDS (Tax Deducted at Source). This applies to:

  • Salaried employees with additional income from freelancing, consultancy, capital gains, or rental income
  • Business owners and professionals (doctors, lawyers, architects, CAs)
  • Investors earning significant capital gains from stocks, mutual funds, or property
  • Freelancers and consultants with variable income
  • Rental income earners with substantial property earnings
Good News: Senior citizens (resident individuals aged 60 years or above) without business or professional income are exempt from paying advance tax.

Advance Tax Due Dates for FY 2025-26

For individual taxpayers and businesses (excluding those opting for presumptive taxation under Section 44AD/44ADA), the advance tax payment schedule is as follows:

Installment Due Date Minimum Tax to be Paid Cumulative %
Q1 June 15, 2025 15% of total tax liability 15%
Q2 September 15, 2025 30% of total tax liability 45%
Q3 December 15, 2025 30% of total tax liability 75%
Q4 March 15, 2026 25% of total tax liability 100%

Important: Taxpayers opting for presumptive taxation under Section 44AD (business) or Section 44ADA (profession) must pay 100% of their advance tax by March 31, 2026.

How to Calculate Advance Tax for FY 2025-26

Follow these steps to estimate your advance tax liability:

Step 1: Estimate Your Total Income

Include all sources of income:

  • Salary income (if applicable)
  • Business or professional income
  • Capital gains (stocks, mutual funds, property)
  • Rental income
  • Interest income from FDs, savings accounts
  • Any other income

Step 2: Claim Applicable Deductions

Deduct eligible investments and expenses under:

  • Section 80C (PPF, ELSS, LIC, tuition fees) – Up to ₹1.5 lakhs
  • Section 80D (Health insurance) – Up to ₹25,000/₹50,000
  • Section 80G (Donations)
  • Section 24(b) (Home loan interest) – Up to ₹2 lakhs
  • Other applicable sections

Step 3: Calculate Taxable Income

Taxable Income = Total Income – Deductions

Step 4: Compute Tax Liability

Apply the applicable tax slabs. Under the New Tax Regime (Default) for FY 2025-26:

  • Up to ₹4,00,000: Nil
  • ₹4,00,001 – ₹8,00,000: 5%
  • ₹8,00,001 – ₹12,00,000: 10%
  • ₹12,00,001 – ₹16,00,000: 15%
  • ₹16,00,001 – ₹20,00,000: 20%
  • ₹20,00,001 – ₹24,00,000: 25%
  • Above ₹24,00,000: 30%

Add: Health & Education Cess @ 4%

Step 5: Subtract TDS Already Deducted

Advance Tax Payable = Total Tax Liability – TDS Already Deducted

Example Calculation

Mr. Sharma's Profile:

  • Salary income: ₹12,00,000
  • Freelance income: ₹3,00,000
  • Capital gains (STCG): ₹1,00,000
  • Section 80C investments: ₹1,50,000
  • TDS deducted: ₹75,000

Calculation:

  • Total Income: ₹16,00,000
  • Taxable Income: ₹14,50,000
  • Tax on ₹14,50,000 (New Regime): ₹87,500
  • Cess @ 4%: ₹3,500
  • Total Tax: ₹91,000
  • Less TDS: ₹75,000
  • Advance Tax Payable: ₹16,000

For March 15, 2026 (Q4): ₹16,000 × 25% = ₹4,000

Smart Tax Planning Tips for FY 2025-26

  2. Set Reminders: Mark March 15, 2026 on your calendar for the final installment
  3. Use TDS Certificates: Check Form 26AS regularly to track TDS credits
  4. Estimate Conservatively: It's better to slightly overestimate than underpay and face penalties
  5. Plan for Capital Gains: If planning to sell assets, factor in the tax implications and pay advance tax accordingly
  6. Utilize Section 87A Rebate: Under the new regime, rebate up to ₹60,000 is available for taxable income up to ₹12 lakh
  7. Keep Documentation: Maintain records of all advance tax challans for ITR filing
Pro Tip: If you've missed earlier installments, you can still pay the entire remaining tax liability by March 15, 2026 to avoid Section 234B penalties (if total paid is ≥90% of liability).
