What is Advance Tax in India?
Advance tax is the portion of income tax paid in advance during the financial year instead of a lumpsum payment at the end of the year. Also known as the "pay-as-you-earn" tax, it is payable in installments according to specific due dates set by the Income Tax Department. Under Section 208 of the Income Tax Act, 1961, every person whose estimated tax liability for the year (after reducing TDS and TCS) is ₹10,000 or more is legally required to pay advance tax. Paying advance tax helps the government maintain a continuous flow of revenue while preventing taxpayers from facing a massive cash drain at the end of the fiscal year.
Advance Tax Due Dates & Installment Slabs FY 2025-26
Taxpayers (except those filing under presumptive taxation) must pay their advance tax in four equal installments throughout the financial year. Here is the official installment timeline:
| Due Date | Required Percentage (Cumulative) | Applicability |
|---|---|---|
| On or before 15th June | 15% of net tax | All taxpayers (except Presumptive) |
| On or before 15th September | 45% of net tax | All taxpayers (except Presumptive) |
| On or before 15th December | 75% of net tax | All taxpayers (except Presumptive) |
| On or before 15th March | 100% of net tax | All eligible taxpayers (including Presumptive) |
Exemptions from Advance Tax
While advance tax is mandatory for most taxpayers, the Income Tax Act provides key exemptions to ease compliance burdens:
- Senior Citizens: Resident individuals aged 60 years or above who do not have any business or professional profits are completely exempt from advance tax. Even if their tax liability exceeds ₹10,000, they can pay it during normal return filing.
- Salaried Employees: If you are a salaried employee with no other major sources of income, your employer will automatically compute and deduct TDS (Tax Deducted at Source) every month. You do not need to pay advance tax unless you have other income (e.g. rent or stock gains) that hasn't been reported to your employer.
- Low Tax Liability: If your net estimated tax payable (after subtracting TDS) is less than ₹10,000, you are exempt from making advance tax payments.
Step-by-Step Advance Tax Calculation Example
To understand how advance tax is computed under the presumptive taxation scheme (Section 44ADA for professionals), let's look at a practical example:
Scenario: You are a freelance software developer with gross annual receipts of ₹15,00,000 during the financial year.
- Step 1: Presumptive Income — Under Section 44ADA, 50% of your gross receipts is deemed as taxable income. Taxable Income = ₹15,00,000 x 50% = ₹7,50,000.
- Step 2: Chapter VI-A Deductions — Suppose you invest ₹1,50,000 in PPF and ELSS mutual funds. Net Taxable Income = ₹7,50,000 - ₹1,50,000 = ₹6,00,000.
- Step 3: Income Tax Liability — Under the New Tax Regime slabs:
- Up to ₹3,00,000: Nil tax
- ₹3,00,001 to ₹6,00,000: 5% of ₹3,00,000 = ₹15,000
- Gross Tax = ₹15,000
- Step 4: Health & Education Cess — 4% of gross tax. Cess = ₹15,000 x 4% = ₹600. Total Tax = ₹15,600.
- Step 5: TDS Credit — Suppose your clients have already deducted TDS of ₹5,000 (under Section 194J) on payments. Net Tax Payable = ₹15,600 - ₹5,000 = ₹10,600.
Conclusion: Since your net payable tax exceeds the ₹10,000 threshold, you must pay an advance tax of ₹10,600 on or before March 15th of the financial year.
Penalties for Default or Delay (Section 234B & 234C)
Failure to pay the appropriate amount of advance tax on time triggers interest penalties. These are evaluated under two distinct sections:
- Section 234C (Delay in Installments): Interest is levied at 1% per month for a period of 3 months (except for the March installment, which is for 1 month) on the amount of shortfall in each quarterly installment.
- Section 234B (Default in Payment): If you fail to pay advance tax or the advance tax paid is less than 90% of your total assessed tax, you will pay interest at 1% per month on the shortfall, computed from April 1st of the next financial year until the date of actual payment.
