Advance tax is a system under which taxpayers in India pay their income tax liability in advance (during the financial year itself) rather than in a lump sum at the end of the year. It is governed by Sections 207-219 of the Income Tax Act, 1961, and applies to all taxpayers (individuals, companies, firms) whose estimated tax liability for the financial year exceeds ₹10,000 — after considering TDS already deducted. Advance tax is particularly important for people who have income not covered by TDS — such as capital gains, rental income, business income, freelance income, interest on FDs, and any other income where the payer does not deduct TDS. For salaried employees, the employer's TDS usually covers the tax on salary; however, if there is additional income (from freelancing, stock trading, rental property), the employee may need to pay advance tax on the additional income. Advance tax is paid in four instalments during the financial year: 15% of estimated annual tax by June 15, 45% by September 15, 75% by December 15, and 100% by March 15. Failure to pay advance tax (or paying less than the required instalment amount) results in penal interest under Section 234C (for shortfall in each instalment) and Section 234B (for paying less than 90% of total tax by March 31). Senior citizens (60+) who do not have business or professional income are exempt from advance tax — they can pay all tax via self-assessment tax after the year ends.
Advance Tax Each Instalment: Instalment 1 (by Jun 15): 15% of estimated annual tax; Instalment 2 (by Sep 15): 45% of estimated annual tax; Instalment 3 (by Dec 15): 75% of estimated annual tax; Instalment 4 (by Mar 15): 100% of estimated annual tax; Interest under 234C = Shortfall × 1% per month (or part month) for 3 months per instalment; Interest under 234B = (Assessed Tax − TDS − Advance Tax) × 1% per month from April 1
- 1Estimate your total income for the financial year: sum of salary (net of standard deduction), house property income, capital gains, business income, freelance income, FD interest, dividend income, and any other income.
- 2Deduct all eligible Chapter VI-A deductions (80C, 80D, 80CCD(1B), etc.) and exemptions to arrive at the estimated taxable income; compute tax on this at applicable slab rates and add 4% cess.
- 3Subtract TDS already deducted (or expected to be deducted by your employer and other deductors) from the total estimated tax; if the remaining liability exceeds ₹10,000, advance tax is required.
- 4Compute each instalment: 15% of total advance tax by June 15; cumulative 45% by September 15 (so 30% additional); cumulative 75% by December 15 (30% additional); cumulative 100% by March 15 (25% additional).
- 5Pay advance tax using Challan 280 on the Income Tax portal (incometax.gov.in) online; select 'Advance Tax' as the payment type and the relevant financial year.
- 6Adjust for changes: if your income estimate changes during the year (e.g., you sell shares in November creating capital gains), recalculate and adjust subsequent instalments — you can pay more in December to make up for any deficit.
- 7File ITR before the due date (typically July 31 for individuals) and compute self-assessment tax for any remaining liability after TDS, advance tax, and credits; pay self-assessment tax using Challan 280 before filing.
Freelancers with no TDS deducted must pay full advance tax; TCS by clients counts as credit
Net income = ₹12L - ₹3L = ₹9L. Tax: 0 on ₹2.5L + 5% on ₹2.5L = ₹12,500 + 20% on ₹4L = ₹80,000. Hmm, at new regime: 0+5%×3L+10%×3L+15%×2.5L = 15K+30K+37.5K = ₹82,500 + cess ₹3,300 = ₹85,800. Instalments: 15% = ₹12,870; 45% = ₹38,610; 75% = ₹64,350; 100% = ₹85,800.
Employer TDS covers salary; employee must pay advance tax on capital gains separately
Salaried employees whose employer covers salary TDS but who have additional capital gains or rental income must pay advance tax on the additional income if it exceeds ₹10,000. LTCG tax at 12.5% on ₹3L = ₹37,500 > ₹10,000 threshold.
234C interest is 1% per month (simple) on shortfall for a maximum of 3 months per instalment
Section 234C applies when advance tax instalments are less than the required percentages. For the September 15 instalment, the required cumulative amount was ₹45,000 (45%); ₹10,000 was paid — shortfall ₹35,000. Interest = ₹35,000 × 1% × 3 = ₹1,050.
234B interest runs from April 1 to date of self-assessment tax payment; 4 months April-July here
Section 234B interest accrues when total advance tax paid (including TDS) is less than 90% of assessed tax. Shortfall = ₹3L - ₹2.5L = ₹50,000. Interest = ₹50,000 × 1% × 4 months (April to July) = ₹2,000.

Capital Gains — Special Advance Tax Rules
LTCG and STCG from equity or property are often unpredictable during the year. Section 234C provides relief: capital gains that arose after the deadline of an instalment are not penalised if included in the next instalment. Specifically: gains arising after December 15 can be included entirely in the March 15 instalment without 234C penalty. However, if you sell shares in April and make large capital gains, these should be included in all subsequent instalments.
Windfalls and One-Time Income
If you receive a one-time large income — lottery winnings, insurance maturity, property sale — during the financial year, you may suddenly need to pay advance tax on this windfall. If the windfall occurs after December 15, the entire tax can be paid by March 15. If it occurs before September 15 or December 15, it should be included in those instalments. Failure to do so results in 234C interest.
Advance Tax for Businesses with Uncertain Income
Businesses with seasonal or variable income find it difficult to estimate advance tax accurately early in the year. The law allows revision of estimates at any instalment — pay more in September or December to catch up if early estimates were low. It is better to slightly overpay advance tax (which is later refunded) than to underpay and face interest charges.
Advance Tax and TCS Credit
Tax Collected at Source (TCS) — collected by sellers on purchase of cars above ₹10 lakh, foreign remittance, luxury goods, and certain other transactions — also counts as a tax credit, just like TDS. TCS credit reflects in Form 26AS and AIS. The net advance tax required = Total tax − TDS − TCS − advance tax already paid. Many buyers of luxury goods overlook TCS credit when computing advance tax.
| Instalment | Due Date | Cumulative % of Annual Tax | Interest for Shortfall (234C) |
|---|---|---|---|

| 2nd Instalment | September 15, 2024 | 45% (additional 30%) | 1% per month × 3 months |
| 3rd Instalment | December 15, 2024 | 75% (additional 30%) | 1% per month × 3 months |
| 4th Instalment | March 15, 2025 | 100% (additional 25%) | 1% per month × 1 month |
| Section 234B | April 1 onwards | If total advance tax < 90% of assessed tax | 1% per month till payment |
| Section 234A | July 31 onwards | For late filing of ITR | 1% per month on outstanding tax |
Who is required to pay advance tax?
Any taxpayer whose estimated tax liability for the financial year exceeds ₹10,000 (after deducting TDS already deducted) must pay advance tax. This includes salaried employees with additional income (capital gains, FD interest, rental income), freelancers, business owners, professionals, and investors. Senior citizens (60+) who do not have income from business or profession are exempt from advance tax.
What happens if I miss an advance tax instalment?
Missing or under-paying an advance tax instalment attracts interest under Section 234C at 1% per month (simple interest) on the shortfall for a period of 3 months for each instalment (June, September, December) and 1 month for the March instalment. If you missed all instalments and the total advance tax paid is less than 90% of assessed tax, Section 234B interest also applies at 1% per month from April 1 till the date you pay.
Do I need to pay advance tax if my employer deducts TDS on salary?
If your only income is salary and the employer's TDS covers all your tax, you do not need to pay advance tax separately. However, if you have other income — capital gains from stocks/mutual funds, rental income, FD interest, freelance income, cryptocurrency gains — the tax on these may not be covered by employer TDS. If the additional tax liability exceeds ₹10,000, you must pay advance tax on these other income sources.
How do I calculate advance tax for capital gains?
Capital gains tax is often uncertain during the year (you may not know when you'll sell assets). The advance tax law provides some relief: for capital gains arising later in the year — if LTCG arises after December 15, the entire LTCG tax can be paid by March 15 without 234C interest. If STCG/LTCG arises before December 15, it should be included in the December instalment. Plan large asset sales around these dates to minimise advance tax complexity.
Can I use Challan 280 to pay advance tax online?
Yes. Advance tax is paid using Challan 280 on the Income Tax portal (incometax.gov.in). Select 'Income Tax (other than companies)' as the tax type, choose '0100 — Advance Tax' as the payment type, select the assessment year, and enter the tax amounts. Payment can be made via net banking, UPI, debit card, or NEFT/RTGS. Keep the payment challan (counterfoil or online receipt) for your records.
Is advance tax applicable for presumptive taxation schemes?
Taxpayers under presumptive taxation schemes (Section 44AD for small businesses with turnover < ₹3 crore, or 44ADA for professionals with receipts < ₹75 lakh) must pay the entire advance tax in one instalment by March 15 — not in four instalments. This simplification is a major benefit of presumptive taxation. If they miss the March 15 deadline, Section 234C interest applies for one month.
What is the difference between advance tax and self-assessment tax?
Advance tax is paid in instalments during the financial year itself (before March 31). Self-assessment tax is paid after the year ends — when you compute your actual tax liability in the ITR and find that TDS + advance tax paid is not sufficient. Self-assessment tax must be paid before filing the ITR. Delaying self-assessment tax payment beyond July 31 (ITR due date) attracts Section 234A interest at 1% per month.
How does advance tax work for someone who started freelancing mid-year?
If you start freelancing in November (and have no freelance income before), you need to estimate the tax on income earned from November to March. If this tax exceeds ₹10,000, pay it by March 15 as the final advance tax instalment. Sections 234C typically does not apply for income that arose for the first time after the September or December deadline — but if you had earlier freelance income and ignored it, interest applies on the shortfall from those earlier dates.
プロのヒント
If you are a salaried employee with significant FD interest, ask your employer to consider an estimated interest income when computing TDS — mention this in your annual investment declaration. This way, the employer deducts slightly higher TDS on salary to cover the FD interest tax, and you avoid having to pay advance tax separately. This is perfectly legal under Section 192(2B) of the Income Tax Act.
ご存知でしたか？
The advance tax system in India was first introduced in 1944 during World War II to fund wartime expenditure — the government needed money in advance rather than waiting for the year-end tax assessment. Today, over ₹8 lakh crore of advance tax is collected annually, representing approximately 40% of total direct tax collections. The system effectively makes taxpayers co-finance government expenditure throughout the year.
