Complete Guide to Advance Tax Payment: Due Dates, Calculator & Installment Details
Advance tax is an important part of India’s income-tax system, yet many taxpayers are often unsure about how it works or whether they need to pay it. In simple terms, advance tax is the tax you pay during the financial year instead of waiting to pay the entire amount at the end. The government collects taxes in installments to ensure a steady flow of revenue—and taxpayers benefit by avoiding a heavy year-end burden. This guide explains the due dates, eligibility, calculation process, payment procedure, and installment structure in a clear and practical way.
As we move deeper into the financial year, it’s important to remember that the Q3 advance tax installment is approaching soon, i.e. 15th December 2025, making this a good time to check your calculations and ensure timely payment.
What Is Advance Tax?
Advance tax is also called the “pay-as-you-earn” tax. Instead of filing your income tax return (ITR) and paying tax in one go after the year ends, you estimate your yearly taxable income and pay tax in four separate installments.
If your total tax liability for a financial year is ₹10,000 or more after claiming TDS, TCS, and tax credits, you must pay advance tax.
Who Has to Pay Advance Tax?
Advance tax applies to several categories of taxpayers. Here’s a quick breakdown:
1. Salaried Individuals
If your salary receives sufficient TDS from your employer, you may not need to pay advance tax. However, if you earn additional income—like rent, capital gains, freelancing, or interest—your tax liability may exceed ₹10,000. In that case, advance tax becomes applicable.
2. Business Owners & Professionals
Individuals with income from business or profession must pay advance tax if their tax due is ₹10,000 or more.
3. Companies
All companies, regardless of income level, must pay advance tax.
4. Presumptive Taxation Scheme Taxpayers
Taxpayers opting for presumptive income under Section 44AD or 44ADA must pay 100% of advance tax in one single installment on or before 15th March.
Due Dates for Advance Tax Payments
Here is the installment schedule for individuals and businesses (other than presumptive taxpayers:
| INSTALLMENT | DUE DATE | % of TOTAL TAX TO BE PAID |
| 1st Installment | 15th June | 15 % |
| 2nd Installment | 15th September | 45 % (cumulative) |
| 3rd Installment | 15th December | 75% (cumulative) |
| 4th Installment | 15th March | 100% |
Reminder: The Q3 Advance Tax Due Date Is Approaching
The third installment is due on 15 December, which requires you to pay 75% of your total estimated tax for the year (after adjusting TDS). If you haven’t reviewed your income estimates recently, now is the best time to do so to avoid last-minute rush and interest charges.
How to Calculate Advance Tax Easily
Calculating advance tax doesn’t require complex accounting skills. Just follow these straightforward steps:
Step 1: Estimate Your Total Income
Add up all incomes you expect during the financial year:
- Salary
- Business or professional income
- Rent from property
- Interest from bank deposits or bonds
- Capital gains
- Any other taxable income
Step 2: Deduct Expenses & Deductions
Subtract:
- Standard deduction
- Allowable business expenses
- Deductions under Sections 80C, 80D, 80G, etc.
Step 3: Apply the Tax Slabs
Compute tax according to the chosen tax regime (old or new).
Step 4: Deduct TDS/TCS
Reduce tax already deducted or collected on your behalf.
Step 5: If Tax Due ≥ ₹10,000
You must pay advance tax.
Example for Better Understanding
Say your estimated income results in a tax liability of ₹60,000 after TDS adjustments:
- 15 June: 15% = ₹9,000
- 15 September: 45% cumulative = ₹27,000 (pay additional ₹18,000)
- 15 December: 75% cumulative = ₹45,000 (pay additional ₹18,000)
- 15 March: 100% = ₹60,000 (pay additional ₹15,000)
Since Q3 is nearing, you should ensure your cumulative tax paid is at 75% by 15 December.
Interest for Missing or Delaying Payment
Delay or underpayment results in interest under:
- Section 234C – for missing installment targets
- Section 234B – for paying less than 90% of total tax by year-end
Paying the Q3 installment on time prevents unnecessary charges and ensures smooth compliance.
Why Advance Tax Matters
Paying advance tax on time offers several benefits:
- Reduces financial stress at the end of the year
- Avoids interest and penalties
- Helps you stay compliant with tax obligations
- Improves financial planning
- Eliminates last-minute tax pressure
Conclusion
Advance tax may seem complex initially, but once you understand its purpose, due dates, and calculation method, it becomes much easier to manage. With the Q3 due date approaching on 15 December, this is the perfect time to review your income, update your calculations, and pay the required amount. A timely payment not only safeguards you from penalties but also ensures a smoother financial year-end.
