Advance Tax in India: Pay as You Earn
Most salaried people never think about advance tax because their employer deducts TDS every month. But if you earn from freelancing, business, rent, capital gains, or any source where TDS is not fully deducted, you may need to pay advance tax yourself, in instalments through the year. Missing the deadlines means interest penalties. Here is everything you need to know.
How Advance Tax Works
Advance tax is simply income tax paid in advance, during the same year you earn the income, instead of waiting until you file your return. The logic is “pay as you earn”. If your total tax for the year (after subtracting TDS) is Rs 10,000 or more, you must pay it in instalments.
Salaried employees usually do not need to pay advance tax because their employer handles TDS. But freelancers, business owners, landlords, and investors often do, because little or no TDS is deducted on their income.
Who Must Pay Advance Tax?
- Freelancers and professionals: If clients deduct only 10% TDS (or none for foreign clients), you likely owe advance tax on the rest.
- Business owners: Business profits rarely have TDS deducted, so advance tax applies.
- Landlords: If your tenant does not deduct TDS, or the TDS is less than your actual liability, advance tax fills the gap.
- Investors: Capital gains from shares, mutual funds, or property usually have no TDS. You must estimate and pay advance tax on them.
- Anyone with total tax of Rs 10,000+: This is the threshold. Below it, no advance tax is needed.
Exception: Senior citizens (60+) with no business income are exempt from advance tax entirely.
The Four Due Dates
Advance tax is paid in four instalments:
- 15 June: At least 15% of your total estimated tax
- 15 September: At least 45% (cumulative)
- 15 December: At least 75% (cumulative)
- 15 March: 100% of your total estimated tax
These are cumulative targets. So by September, you should have paid 45% of the full year’s tax in total, not 45% extra on top of June.
Special rule for 44ADA/44AD: If you are under presumptive taxation, you pay the entire amount in one instalment by 15 March. No quarterly payments needed.
What Happens If You Miss the Deadlines?
Two interest penalties apply:
Section 234B: If you paid less than 90% of your total tax by 31 March, interest of 1% per month is charged on the shortfall, from April until you pay.
Section 234C: If you missed any quarterly instalment target, interest of 1% per month is charged for 3 months on each shortfall. The last instalment (March) gets 1 month of interest.
These add up fast. On a Rs 1 lakh shortfall, you could pay Rs 12,000 or more in interest alone. It is always cheaper to estimate generously and pay on time.
A Worked Example
Sameer is a freelance designer who files normally (not under 44ADA). He estimates his total income this year at Rs 18 lakh. His total tax comes to roughly Rs 1,70,000. Clients deducted Rs 40,000 as TDS. So his advance tax liability is Rs 1,30,000.
Now take Arjun, a freelance consultant under 44ADA. His advance tax liability is Rs 1,30,000. He pays the entire amount in one instalment by 15 March. Simple.
Now take Kavya, who runs a small business and does not use presumptive taxation. Her advance tax liability is Rs 2,00,000. She must pay:
- 15 June: Rs 30,000 (15%)
- 15 September: Rs 60,000 more (total Rs 90,000 = 45%)
- 15 December: Rs 60,000 more (total Rs 1,50,000 = 75%)
- 15 March: Rs 50,000 more (total Rs 2,00,000 = 100%)

Frequently Asked Questions
How do I pay advance tax?
Online through the Income Tax e-filing portal (incometax.gov.in). Go to e-Pay Tax, select Assessment Year, choose “Advance Tax” as the payment type, and pay via net banking, debit card, or UPI.
What if my income estimate changes during the year?
That is normal. You can adjust in later instalments. If you earn more than expected, pay extra in December or March. If you earn less, reduce the later payments. Just make sure the cumulative percentages are met.
Do I need to pay advance tax on capital gains?
Yes. Capital gains often have no TDS, so you must include them in your advance tax estimate. If the gain happens late in the year (say February), you get some relief on the earlier instalment penalties.
What if I am salaried but also earn freelance income?
Your employer handles TDS on salary, but you must pay advance tax on the freelance portion if the total extra tax is Rs 10,000 or more.
Can I get a refund if I overpay advance tax?
Yes. When you file your return, any excess is refunded with interest. It is better to slightly overpay than to underpay and face penalties.
Is there any penalty for the March instalment specifically?
Yes, under Section 234C, a shortfall in the March instalment attracts 1% interest for one month. Small, but still worth avoiding.
