Advance Tax Due Dates 2026: Interest & Penalty Guide
Most salaried employees never think about advance tax — their employer’s monthly TDS takes care of it. But if you have income beyond your salary — rental income, freelance projects, capital gains, FD interest, dividends — you are almost certainly liable to pay advance tax in quarterly installments. Miss those installments, and the interest clock starts ticking automatically. This guide gives you every due date, every interest rate, and every calculation you need for FY 2026-27.
Who Must Pay Advance Tax?
Advance tax applies to every taxpayer — individual, HUF, firm, or company — whose estimated tax liability for the year exceeds ₹10,000 after accounting for TDS already deducted or expected to be deducted.
| Taxpayer Type | Advance Tax Applicable? | Note |
|---|---|---|
| Salaried — only salary income, TDS covers full liability | ❌ Generally No | Employer TDS acts as advance tax |
| Salaried + additional income (rent, FD interest, capital gains) | ✅ Yes — on the additional income | Net liability after salary TDS must exceed ₹10,000 |
| Freelancer / self-employed professional | ✅ Yes | No employer TDS — full liability on self |
| Business owner | ✅ Yes | Unless under presumptive scheme |
| Senior citizen (60+) — no business income | ❌ Exempt | Only pension/interest/rental income |
| Presumptive taxpayer (44AD/44ADA) | ✅ Yes — but single installment | 100% by March 15 only |
Advance Tax Due Dates — FY 2026-27
| Installment | Due Date | Minimum Cumulative % to Pay |
|---|---|---|
| 1st Installment | June 15, 2026 | At least 15% of estimated annual tax |
| 2nd Installment | September 15, 2026 | At least 45% (cumulative) |
| 3rd Installment | December 15, 2026 | At least 75% (cumulative) |
| 4th Installment | March 15, 2027 | 100% (full year) |
Presumptive Taxpayers — Single Installment
If you have opted for Section 44AD (business, turnover ≤ ₹3 crore) or Section 44ADA (specified professions, receipts ≤ ₹75 lakh), the quarterly schedule does not apply. You must pay 100% of your advance tax in a single installment by March 15, 2027. Miss this single deadline and interest under Section 234B applies from April 1, 2027 onwards.
Interest for Missing Installments — Section 234C
Section 234C charges interest when individual installments fall short of the required cumulative percentages. It applies even if you ultimately pay the full tax by March 31 — past shortfalls are not erased by later payments.
| Installment Shortfall | Interest Rate | Period Charged |
|---|---|---|
| June 15 shortfall (below 15%) | 1% per month | 3 months |
| September 15 shortfall (below 45%) | 1% per month | 3 months |
| December 15 shortfall (below 75%) | 1% per month | 3 months |
| March 15 shortfall (below 100%) | 1% per month | 1 month |
Section 234C — Worked Example
Arvind, a Delhi-based consultant, has estimated annual tax of ₹4,50,000. He pays nothing by June 15 or September 15, pays ₹4,50,000 in one shot on February 10, 2027.
| Missed Installment | Shortfall | Interest |
|---|---|---|
| June 15 (should have paid 15% = ₹67,500) | ₹67,500 | ₹67,500 × 1% × 3 = ₹2,025 |
| September 15 (should have paid 45% = ₹2,02,500) | ₹2,02,500 | ₹2,02,500 × 1% × 3 = ₹6,075 |
| December 15 (should have paid 75% = ₹3,37,500) | ₹3,37,500 | ₹3,37,500 × 1% × 3 = ₹10,125 |
| Total Section 234C Interest | ₹18,225 |
Interest for Overall Shortfall — Section 234B
Section 234B is a separate charge — it applies when total advance tax paid during the year is less than 90% of the assessed tax liability. This is the “year-end shortfall” interest, as opposed to Section 234C’s “installment timing” interest.
Key parameters:
- Rate: 1% per month (simple interest)
- Starts: April 1 following the financial year
- Ends: Date of actual payment (or date of processing the ITR, whichever is earlier)
- Trigger: Total advance tax paid < 90% of assessed tax
- Base: The shortfall amount (assessed tax minus advance tax paid)
Section 234B — Worked Example
Continuing Arvind’s case — he paid ₹4,50,000 in February 2027 (before March 31 — so total paid equals 100% of estimated tax). However, suppose his actual assessed tax comes out to ₹5,00,000 (income was higher than estimated). Total advance tax paid (₹4,50,000) = 90% of ₹5,00,000 — exactly at the threshold. No Section 234B interest in this case.
But if his assessed tax were ₹5,20,000 — advance tax paid (₹4,50,000) = 86.5% of assessed tax, which is below 90%. Section 234B interest applies on the ₹70,000 shortfall from April 1, 2027 until payment.
Capital Gains — Special Rule
Capital gains are unpredictable — you may sell shares or property mid-year without advance planning. The law accommodates this:
- Capital gains arising after March 15: The entire tax on those gains can be paid by March 31 without any Section 234C interest
- Capital gains arising between December 15 and March 15: Include in the March 15 installment — no retrospective 234C interest for earlier quarters
- Capital gains arising before December 15: Should be included proportionately in the installment falling due after the gain arises
This provision is specifically designed to avoid penalizing taxpayers for income events they could not have predicted at the start of the year.
Section 234A — Late Filing Interest
Section 234A is separate from advance tax — it applies when the ITR itself is filed after the due date. However, it interacts with Section 234B:
- Section 234B runs from April 1 until the date of payment or ITR filing (whichever is earlier)
- Section 234A runs from the ITR due date until the date of actual filing
- The two do not overlap — 234B stops where 234A begins
- Rate: Same — 1% per month simple interest
| Interest Section | Trigger | Period | Rate |
|---|---|---|---|
| Section 234A (423 under ITA 2025) | ITR filed after due date | Due date to filing date | 1% per month |
| Section 234B (424 under ITA 2025) | Total advance tax < 90% | April 1 to payment date | 1% per month |
| Section 234C (425 under ITA 2025) | Installment shortfalls | 3 months per shortfall (1 month for March) | 1% per month |

Common Mistakes
Mistake 1 — Ignoring advance tax because “I’ll sort it at ITR time”:
Paying all tax while filing your ITR is allowed, but Section 234B interest runs from April 1 for the shortfall, and Section 234C interest has already accrued for each missed installment. The total interest bill can be substantial — and entirely avoidable.
Mistake 2 — Presumptive taxpayers missing the March 15 single deadline:
Under 44AD/44ADA, there is only one date — March 15. There is no quarterly schedule and therefore no quarterly reminder. Many presumptive taxpayers miss this because they assume the four-date schedule applies to them. Set a dedicated reminder for March 15 every year.
Mistake 3 — Not revising estimates when income changes significantly mid-year:
If you land a large project in August, or make a significant capital gain in October, revise your advance tax estimate before the December installment. The law does not penalize you for initial under-estimation — it penalizes each installment that falls short of the required cumulative percentage.
Mistake 4 — Selecting wrong Assessment Year while making payment:
For FY 2026-27 advance tax, select AY 2027-28. Getting this wrong means the payment credits to the wrong year — creating a mismatch in your ITR and possibly triggering a demand notice.

Frequently Asked Questions
Q1. If I pay 100% of my advance tax by March 15, do I still face Section 234C interest for earlier missed installments?
Yes — Section 234C interest for each installment shortfall is calculated as of the installment date and cannot be reversed by later payments. Paying 100% by March 15 avoids Section 234B (the year-end shortfall interest), but Section 234C interest for June, September, and December shortfalls is already locked in.
Q2. What is the 90% safe harbor rule under Section 234B?
If total advance tax paid during the year is at least 90% of the finally assessed tax liability, Section 234B interest does not apply. This provides a buffer for income estimation errors — you are not penalized for small miscalculations that result in a modest year-end balance.
Q3. I am a salaried employee with some rental income — do I need to pay advance tax?
If your total tax liability after accounting for salary TDS exceeds ₹10,000, then yes. Calculate your rental income tax, subtract the salary TDS already being deducted, and if the net exceeds ₹10,000, you need to make up the difference through advance tax installments.
Q4. Can I get a refund if I overpay advance tax?
Yes — any excess advance tax paid over your actual liability is refunded when you file your ITR. The refund also carries interest under Section 244A at 0.5% per month from April 1 of the Assessment Year until the refund is processed. Overpaying carries no penalty.
Q5. What happens if I receive a capital gain in February — do I need to revise earlier installments?
No — capital gains arising after December 15 can be included in the March 15 installment without any retrospective Section 234C interest for the earlier quarters. Capital gains arising after March 15 can be paid by March 31 with no 234C interest at all.
Conclusion
Advance tax is not complicated — it is simply a matter of estimating your annual income, computing the tax, and paying it in four installments on time. The interest provisions (234B and 234C) are automatic and calculated by the ITR system — there is no opportunity to negotiate them away after the fact.
The simplest approach: estimate your annual income in April, compute the tax, set calendar reminders for June 15, September 15, December 15, and March 15, and pay each installment a few days before the due date to avoid any last-minute bank processing issues. If your income changes materially during the year, revise the estimate before the next installment. That is all it takes to stay entirely interest-free on advance tax.
