Everything regarding Advance Tax

Everything regarding Advance Tax

If your estimated tax liability for FY 2026-27 exceeds Rs. 10,000 after deducting TDS and TCS credits, you are required to pay advance tax in four instalments across the year — 15 June, 15 September, 15 December and 15 March. Missing or under-paying any instalment triggers interest under Section 234C at 1% per month. A cumulative shortfall below 90% of your assessed tax adds a separate Section 234B charge from 1 April of the assessment year. This guide works through every rule — with rupee examples, step-by-step payment instructions and common traps — so you can manage FY 2026-27 (AY 2027-28) without interest leakage.

Who Must Pay Advance Tax — and Who Gets an Exemption

Every taxpayer — individual, Hindu Undivided Family (HUF), firm, Limited Liability Partnership (LLP) or company — must pay advance tax if the net tax liability for the year exceeds Rs. 10,000 after deducting expected TDS and TCS credits. This applies regardless of the nature or scale of income.

Two meaningful carve-outs exist:

1. Senior citizens (age 60 and above) without business income are exempt under Section 207 of the Income-tax Act, 1961. They pay self-assessment tax in one shot before filing their ITR. The exemption vanishes the moment a senior citizen earns even a modest professional fee, commission, or any other business income — at that point, the full four-instalment schedule applies from June onwards.

1. Salaried employees whose entire tax liability is covered by employer TDS (Form 16) ordinarily stay out of scope. However, if you earn freelance income, rental income, capital gains, or significant interest on deposits — and the residual tax on that income exceeds Rs. 10,000 — you are firmly in scope and must pay in instalments.

Non-resident Indians and foreign companies with Indian-source income are also liable; the Rs. 10,000 threshold applies universally. There is no exemption based on residential status alone.

Advance Tax Due Dates for FY 2026-27 (AY 2027-28)

The instalment schedule under Section 211 remains unchanged for FY 2026-27. If a due date falls on a bank holiday or public holiday, the payment made on the next working day is treated as timely.

Taxpayers opting for presumptive taxation under Sections 44AD or 44ADA are required to pay 100% of estimated tax in a single instalment by 15 March 2027. The June, September and December deadlines do not apply to them, but the March deadline is absolute.

How to Calculate Your Advance Tax in Four Steps

Advance tax is entirely self-assessed. You estimate your own income, compute the tax, and schedule payments. The process is iterative — you refine the estimate at each quarter.

Step 1 — Map all income heads. List salary (net of standard deduction), income from house property (net of 30% standard deduction and interest), business or professional income, capital gains realised so far plus any you reasonably anticipate, and income from other sources (FD interest, dividends, freelance honoraria).

Step 2 — Compute gross tax. Apply the regime you have chosen (old or new) for AY 2027-28. Add applicable surcharge (if income exceeds Rs. 50 lakh). Add the 4% Health and Education Cess on (basic tax + surcharge). When uncertain, use a slightly higher estimate — overpaying advance tax generates a refund with Section 244A interest; underpaying generates 234C interest that you cannot deduct anywhere.

Step 3 — Subtract expected TDS and TCS for the full year. Use client-wise projections, TDS certificates received so far, and your Annual Information Statement (AIS) on the income tax portal. Count only TDS that will actually be deducted before 31 March 2027.

Step 4 — Arrive at net advance tax. If the result exceeds Rs. 10,000, pay in instalments aligned to the cumulative percentages above. Refresh this calculation after each quarter-end — TDS receipts and income rarely land exactly as projected.

Worked Example: Priya's Advance Tax for FY 2026-27

Scenario: Priya is a freelance UX designer in Pune. Her clients deduct TDS at 10% on invoices. She operates under the new tax regime.

After applying the applicable new-regime slabs for AY 2027-28 and adding 4% cess, Priya's CA estimates total tax at Rs. 4,80,000.

Expected TDS:

• TDS on fees @ 10% of Rs. 30,00,000 = Rs. 3,00,000
• TDS on FD interest = Rs. 4,000
• Total TDS expected = Rs. 3,04,000
• But wait — Rs. 3,04,000 covers most of the Rs. 4,80,000 tax. Net advance tax = Rs. 4,80,000 − Rs. 3,04,000 = Rs. 1,76,000

Instalment Schedule

Each quarter, Priya also reconciles TDS actually received (reflected in AIS) and adjusts the instalment upward or downward accordingly.

What Happens If Priya Skips September?

By 15 September, Priya should have paid Rs. 79,200 cumulatively. She only paid Rs. 26,400 in June.

• Shortfall = Rs. 52,800
• Section 234C interest = 1% × 3 months × Rs. 52,800 = Rs. 1,584

She also skips December. By 15 December, cumulative required = Rs. 1,32,000. Paid so far = Rs. 26,400.

• Shortfall = Rs. 1,05,600
• 234C interest = 1% × 3 months × Rs. 1,05,600 = Rs. 3,168

Total avoidable interest: Rs. 4,752 — from nothing more than missing two calendar reminders.

Section 44AD and 44ADA: The One-Instalment Rule

If you run an eligible business within the prescribed turnover limits under Section 44AD, or are a specified professional (doctor, lawyer, architect, CA, engineer, consultant, etc.) within the prescribed gross receipts threshold under Section 44ADA, the four-instalment structure collapses into one:

• Pay 100% of your estimated tax by 15 March 2027 — no June, September or December payments required.
• If you underpay or miss 15 March, Section 234C interest runs at 1% for one month only (not three), because there is just one prescribed instalment.
• Section 234B still applies if your total advance tax + TDS falls below 90% of assessed tax.

Critical edge case: If you declared income under 44AD in the previous year but opt out in FY 2026-27 to maintain regular books, you revert to the four-instalment schedule from June 15 onwards — and you are ineligible to re-enter presumptive taxation for the next five consecutive years (Section 44AD(4)). This switch has immediate advance-tax planning implications from the very first instalment.

Capital Gains and Dividend Income: Special Timing Rules

Capital gains are lumpy by nature. A single equity portfolio liquidation or a property sale in one month can change your tax liability dramatically. The Income-tax Act accommodates this with a specific rule for advance tax timing.

The rule: Advance tax on capital gains (all types) and dividend income is due only in the instalment immediately following the quarter in which the income arises. Section 234C interest is not levied on the shortfall for any earlier instalments with respect to these income heads.

Worked illustration:

• Shyam sells equity mutual fund units in October 2026 (Q3 of FY 2026-27), realising a Long-Term Capital Gain (LTCG) under Section 112A of Rs. 4,00,000 above the applicable LTCG exemption limit.
• Tax on this LTCG at the applicable rate as notified for AY 2027-28 must be included in his 15 December 2026 instalment — because October falls after the September deadline.
• If Shyam left this out of June and September payments, no Section 234C interest applies to those earlier quarters for this income specifically.
• If he also misses December, the tax on this gain becomes payable by 15 March 2027, and a one-month 234C charge applies on the March shortfall.

Capital gains arising between 16 December 2026 and 31 March 2027: Tax on these gains must be paid by 15 March 2027. If not paid by March 15, 234C interest at 1% for one month applies on that shortfall.

Dividend income: Since the Dividend Distribution Tax (DDT) was abolished from FY 2020-21, dividends are taxable in your hands at applicable slab rates. The same timing accommodation applies — pay advance tax on dividends in the instalment after you receive them.

Practical note for equity investors: Mutual fund capital gains reports and broker tax computation statements are usually available a few weeks after quarter-end. Download them from the AMC or broker portal as soon as they are published and fold the figures into your advance tax estimate before the next due date.

How to Pay Advance Tax Online: Challan ITNS-280, Step by Step

All advance tax payments route through the e-Pay Tax facility on incometax.gov.in. The migration to Income Tax Portal v3 (MCA-V3 style infrastructure) is complete; use the official portal only.

1. Log in at incometax.gov.in → e-File → e-Pay Tax → select New Payment.
2. Select ITNS 280 — the challan for income tax payment.
3. Under "Tax Applicable", choose (0021) Income-tax (Other than Companies) for individuals, HUFs, firms and LLPs; choose (0020) Corporation Tax for companies.
4. Under "Type of Payment", select (100) Advance Tax. Do not select 300 (Self-Assessment) by mistake — a wrong type cannot be self-corrected online.
5. Assessment Year: enter 2027-28 (the year following FY 2026-27). This is the single most common error — taxpayers accidentally enter the current financial year (2026-27) instead of the assessment year.
6. Enter your PAN; confirm name and address auto-populate from PAN records correctly.
7. Enter the payment amount.
8. Choose your payment mode — net banking, debit card, RTGS/NEFT, or over-the-counter at an authorised bank.
9. After successful payment, immediately download the challan PDF. Record: BSR code (7-digit bank branch code), challan serial number, and date of deposit. You will need all three when filling the tax payment schedule in your ITR.
10. Check your AIS (Annual Information Statement) on the portal within 3–5 working days to confirm the advance tax credit appears. Discrepancies should be flagged immediately.

If you entered the wrong AY: There is no online self-correction. You must submit a written challan correction application to your Assessing Officer (AO) with supporting documents. The AO forwards it to the bank through the online Tax Information Network (TIN) system. This process can take four to six weeks. Avoid it entirely with a five-second double-check at Step 5.

Interest for Default: Sections 234B and 234C with Rs. Numbers

Section 234C — Shortfall at Individual Instalments

Interest accrues on the shortfall in each instalment at 1% per month (or part thereof).

• Shortfall at June, September or December instalment: interest for 3 months
• Shortfall at March instalment: interest for 1 month
• Exception for capital gains/dividends: No 234C interest for earlier instalments, provided the tax is included in the instalment after the income arises.

Formula: 234C interest = 1% × relevant months × (cumulative % target of tax − cumulative advance tax and TDS paid to date)

Section 234B — Cumulative Advance Tax Below 90%

Section 234B is a separate and additional charge. It applies when your total advance tax paid is less than 90% of the assessed tax (the tax finally determined when the ITR is processed or assessed).

Interest runs at 1% per month (or part thereof) from 1 April of the assessment year (i.e., 1 April 2027 for AY 2027-28) until the date you pay self-assessment tax under Section 140A.

Worked calculation:

• Assessed tax for AY 2027-28: Rs. 8,00,000
• 90% threshold: Rs. 7,20,000
• Total advance tax paid + TDS credited: Rs. 6,80,000 (shortfall: Rs. 40,000)
• Self-assessment tax paid: 30 September 2027
• Months from 1 April 2027 to 30 September 2027 = 6 months (each month, including any part-month, counts)
• 234B interest = 1% × 6 × Rs. 40,000 = Rs. 2,400

If you delay self-assessment until December 2027 (8 months from April), the same Rs. 40,000 shortfall costs Rs. 3,200. The incentive to file and pay promptly is clear.

Both Section 234B and 234C interest are non-deductible — you cannot offset them against any income head in your return. They are a pure cash cost.

Common Mistakes and How to Avoid Them

1. Wrong Assessment Year on Challan ITNS-280. Advance tax for FY 2026-27 must be paid under AY 2027-28. Paying under AY 2026-27 means the credit lands in the wrong year, leaving a phantom shortfall in AY 2027-28 that triggers 234C even if you actually paid. Always verify before confirming the payment.

2. Counting TDS twice — or not at all. The most common arithmetic error is either forgetting to subtract expected TDS (leading to overpayment and a large refund) or counting TDS you expect but that never actually materialises (leading to underpayment). Reconcile AIS every quarter rather than relying on year-end estimates.

3. Ignoring capital gains from brokers, mutual funds or international platforms. Equity gains, debt fund redemptions, REITs, InvITs, offshore ETFs — all are taxable and all must enter the advance tax computation in the correct instalment window. Foreign broker statements often arrive late; budget time to process them before each due date.

4. Computing tax under the wrong regime mid-year. Once you choose the new or old regime for salary TDS purposes (via declaration to employer), that generally locks the regime for the year. Computing advance tax under the other regime produces a sharp mismatch in March. If you are self-employed, you can switch regimes at ITR filing time, but your advance tax estimates should reflect the regime you actually intend to use.

5. Senior citizens starting a practice or advisory role. Retired professionals often overlook that a fresh engagement — even a token retainer for advisory services — removes the Section 207 exemption entirely. At that point, four missed instalments (June through December) have already accumulated 234C interest by the time the problem is noticed at filing.

6. Skipping the December instalment due to year-end pressure. December is consistently the most-missed instalment. A calendar block on 1 December with a linked task to review AIS and compute the top-up eliminates this pattern.

7. Paying into the correct AY but the wrong "type of payment." Selecting (300) Self-Assessment Tax instead of (100) Advance Tax before the financial year ends does not disqualify the credit — the law treats it as advance tax if paid in time — but it creates reconciliation headaches at filing. Use the correct code from the start.

Coordinating Advance Tax with TDS, AIS and Self-Assessment Tax

Your advance tax computation is only as accurate as your TDS forecast. A quarterly reconciliation routine — not an annual one — is what keeps you out of trouble.

After each quarter-end (30 June, 30 September, 31 December, 31 March):

• Download your updated AIS (Annual Information Statement) from the income tax portal. AIS now consolidates TDS/TCS credits, savings account interest, dividend receipts, capital gains reported by brokers, and high-value transactions — all sourced from third-party filers. It is more comprehensive than Form 26AS, which continues to exist but primarily reflects TDS, TCS, and refund data.
• Cross-check AIS data against your own books. Flag any entries that appear in AIS but not in your records (possible unreported income) and entries in your records that have not appeared in AIS yet (possible TDS not yet deposited by the deductor).
• Reforecast remaining-quarter income. Adjust the estimate upward if business has been better than expected; do not cut it below the conservative floor without clear evidence.
• Compute the advance tax top-up needed before the next due date and transfer it to your bank advance before the 15th.

Self-Assessment Tax (Section 140A) is paid after 31 March 2027 but before filing your ITR. It covers any remaining tax liability after crediting all advance tax instalments and TDS. Section 234B interest runs from 1 April 2027 until the date this payment clears. File your return as soon as self-assessment tax is paid — delay adds Section 234A interest at 1% per month on unpaid tax from the due date of filing to the actual date of filing.

Key Takeaways

• The threshold is Rs. 10,000. Any taxpayer — individual, HUF, firm, LLP, or company — whose net tax liability after TDS and TCS exceeds Rs. 10,000 must pay advance tax in four instalments: 15%, 45%, 75% and 100% (cumulative) by 15 June, 15 September, 15 December and 15 March respectively, for FY 2026-27.
• Senior citizens (60+) without business income are exempt under Section 207; once any business or professional income exists, the full four-instalment schedule applies from June onwards.
• Presumptive taxpayers (44AD and 44ADA) pay 100% in a single instalment by 15 March 2027 — but Section 234C and 234B still apply for shortfalls, and opting out of 44AD triggers the four-instalment schedule immediately.
• Capital gains and dividends attract advance tax only in the instalment after the income arises; no Section 234C interest applies for earlier instalments on these specific incomes.
• Pay via Challan ITNS-280 on incometax.gov.in, select Type of Payment (100) Advance Tax, and always enter Assessment Year 2027-28 — not FY 2026-27. Download and archive the challan with its BSR code before closing the browser.
• Section 234C charges 1% per month (three months for the first three instalments, one month for March) on each instalment shortfall; Section 234B charges 1% per month from 1 April 2027 on any cumulative shortfall below 90% of assessed tax. Both charges are non-deductible.
• Quarterly reconciliation with AIS — not a year-end scramble — is the single most effective habit for eliminating advance tax interest. Check AIS after every quarter-end, update your income forecast, and make the top-up payment before the next due date.
