Advance Tax in India: Who Pays It, How to Calculate It, and Penalties for Missing Deadlines

I didn't pay advance tax for two years when I had freelance income alongside my salary. Cost me ₹4,200 in interest at filing time — not a fortune, but entirely avoidable with a basic understanding of the rule.

Here's everything you need to know about advance tax.

What Is Advance Tax?

The Indian income tax system is pay-as-you-earn. For salaried employees, TDS is deducted every month by the employer — that's their advance tax. But if you have income beyond salary (freelancing, capital gains, rental income, FD interest, business income), you may have tax liability not covered by TDS.

That uncovered liability must be paid in installments during the financial year — not all at once in March. That's advance tax.

Who Must Pay Advance Tax?

You must pay advance tax if your total estimated tax liability (after TDS) exceeds ₹10,000 in a financial year.

Common situations where this applies:

• Freelancers, consultants, and self-employed professionals
• Business owners
• Investors with capital gains (equity, mutual funds, property)
• Employees with rental income or significant FD interest
• Anyone receiving cryptocurrency or other income without TDS

Exceptions:

• Senior citizens (60+) with no business income are exempt from advance tax. They pay at filing.
• Salaried employees where all tax is covered by employer TDS — no advance tax needed unless they have additional income > ₹10,000 tax.

The Four Installment Dates

Note: If you miss any installment, pay as much as you can before the next deadline. The penalty is on the shortfall, not the full amount.

How to Calculate Your Advance Tax

Step 1: Estimate your total income for the year from all sources:

• Salary (from Form 16 or salary slips)
• Business/professional income (estimate conservatively)
• Capital gains (mark-to-market your portfolio)
• Rental income (annual rent)
• FD interest (from bank passbook/interest certificate)

Step 2: Apply deductions (80C, 80D, 80CCD, HRA exemption, etc.)

Step 3: Calculate tax at slab rates (old or new regime)

Step 4: Subtract TDS already deducted (from payslips, Form 26AS)

Step 5: What remains is your advance tax liability.

Example:

• Total income: ₹15L (salary ₹12L + freelance ₹3L)
• Deductions (80C + 80D + NPS): ₹2.5L
• Taxable income: ₹12.5L
• Tax at old regime: ~₹1,62,500 + 4% cess = ~₹1,69,000
• TDS from employer: ₹1,35,000
• Net advance tax due: ₹34,000

Installment schedule:

• June 15: 15% of ₹34,000 = ₹5,100
• September 15: 45% cumulative = ₹15,300 (pay ₹10,200 now)
• December 15: 75% cumulative = ₹25,500 (pay ₹10,200 now)
• March 15: 100% = ₹34,000 (pay ₹8,500 now)

Penalties for Non-Payment — 234B and 234C

Section 234B: If you pay less than 90% of your total tax liability by March 31, you pay 1% per month on the shortfall from April 1 until you actually pay.

Section 234C: For each installment that falls short (June, September, December, March), you pay 1% per month on the shortfall for 3 months per installment.

Example: You had ₹50,000 in advance tax due but paid nothing. At filing in July:

• 234B: 1%/month × 4 months (April–July) × ₹50,000 = ₹2,000
• 234C: applies to each missed installment separately — adds another ₹1,500–₹2,500

It's real money, easily avoided.

How to Pay Advance Tax

1. Go to incometax.gov.in
2. Select "e-Pay Tax"
3. Choose Challan 280 → (100) Advance Tax
4. Enter PAN, assessment year (next year — if FY is 2025-26, select AY 2026-27)
5. Enter the amount and pay via net banking or UPI

Keep the challan receipt. Mention this payment in your ITR.

Freelancers and Capital Gains — Special Cases

Freelancers: Income is irregular, so estimating in June (first installment) is hard. Be conservative — underestimating is fine as long as you catch up by December. Pay a larger chunk in September and December as income becomes clearer.

Capital gains: If you sell property or redeem a large mutual fund position in October, you suddenly have significant capital gains. Calculate the tax on those gains and pay advance tax by December 15 to avoid 234C penalty on the December installment.

New regime vs old regime: Your installment calculations should use whichever regime you plan to file under. If you're switching regimes this year, recalculate estimates using the new regime slabs.

Advance tax isn't complicated — it's just paying now what you'd pay in July anyway. The cost of not doing it is 12–24% annualized interest on the shortfall. That's the highest guaranteed return you'll find in India — just in reverse.
