What is advance tax?
Advance tax is income tax you pay in the same financial year you earn the income. The Income Tax Department treats it as a ‘pay-as-you-earn’ system, ensuring tax flows into the exchequer throughout the year. The rule reaches you once your estimated tax for the year crosses ₹10,000 after TDS and TCS, and from that point the four instalment payment dates apply to you.
Who should pay advance tax?
The threshold of ₹10,000 after deducting TDS and TCS triggers this obligation. This single test typically catches three groups.
- Salaried individuals with extra income from rent, interest, dividends, or capital gains that their employer’s TDS doesn’t cover
- Freelancers, consultants, and gig workers, whose income arrives with no tax deducted at source
- Business owners and professionals, including those opting for presumptive taxation schemes
Resident senior citizens aged 60 or above are exempted from paying advance tax, provided they have no income chargeable under “Profits and gains of business or profession’. They settle their tax when they file their return.
How to calculate advance tax in five steps
Your advance tax is your full-year tax minus everything collected through TDS and TCS. 1 Finance Advance Tax Calculator calculates the amount for you in seconds.
Step 1: Estimate your total income
Add everything you expect to earn this year across salary, business or professional income, rent, capital gains, interest, and dividends.
Step 2: Subtract eligible deductions
Under the old tax regime, claim deductions such as those under Section 123 and Section 126 of the Income Tax Act, 2025, which broadly carry forward the old Section 80C and Section 80D. The new tax regime offers fewer deductions but lower slab rates, so the Advance Tax Calculator compares both and shows you the cheaper one.
Step 3: Apply the income tax slab rates
Compute the total tax on your taxable income under whichever tax regime you choose.
Step 4: Reduce taxes already paid
Subtract any TDS, TCS, and advance tax instalments you have already paid during the year.
Step 5: Pay in instalments if you cross the threshold.
If the remaining tax liability tops ₹10,000, you pay it across the four due dates below.
Advance tax due dates for Tax Year 2026-27
| Due date | Advance tax payment (Cumulative) |
|---|---|
| June 15th, 2026 | 15% of your total tax liability |
| September 15th, 2026 | 45% of your total tax liability |
| December 15th, 2026 | 75% of your total tax liability |
| March 15th, 2027 | 100% of your total tax liability |
Source: Income Tax Department, as of 2026
If you file under the presumptive scheme in Section 58 (other than the goods-carriage category), you skip the quarterly advance tax schedule and pay the full amount in one go by March 15th, 2027.
The Income Tax Act, 2025 replaces Sections 44AD, 44ADA, and 44AE with a unified Section 58 framework.
Advance tax calculator example: Tax liability on ₹70 lakh income in Tax Year 2026-27
Say you are an independent consultant on the new tax regime with your net professional income for Tax Year 2026-27 is ₹70,00,000. A TDS of ₹7,00,000 (10% of your professional receipts) gets deducted. However, this deduction covers only part of your eventual tax liability. You must pay the remaining tax through advance tax instalments. Here’s how the calculation works.
Step-by-step advance tax calculation on ₹70 lakh
| Income slab | Rate | Tax liability |
|---|---|---|
| Up to ₹4,00,000 | Nil | ₹0 |
| ₹4,00,001 to ₹8,00,000 | 5% | ₹20,000 |
| ₹8,00,001 to ₹12,00,000 | 10% | ₹40,000 |
| ₹12,00,001 to ₹16,00,000 | 15% | ₹60,000 |
| ₹16,00,001 to ₹20,00,000 | 20% | ₹80,000 |
| ₹20,00,001 to ₹24,00,000 | 25% | ₹1,00,000 |
| ₹24,00,001 to ₹70,00,000 | 30% | ₹13,80,000 |
| Total tax liability applied before surcharge and cess | - | ₹16,80,000 |
| Surcharge on the income above ₹50,00,000 | 10% | ₹1,68,000 |
| Health and education cess | 4% | ₹73,920 |
| Your total tax liability | - | ₹19,21,920 |
Source: 1 Finance Research; all figures are illustrative
Subtracting ₹7,00,000 (TDS) from ₹19,21,920 (your total tax liability), you owe ₹12,21,920 in advance tax, to be paid across the four due dates as follows.
Advance tax due dates for Tax Year 2026-27: Your quarterly payment schedule
| Due date | Rate | Amount to pay this quarter |
|---|---|---|
| June 15th, 2026 | 15% | ₹1,83,288 |
| September 15th, 2026 | 45% | ₹3,66,576 |
| December 15th, 2026 | 75% | ₹3,66,576 |
| March 15th, 2027 | 100% | ₹3,05,480 |
Source: 1 Finance Research; all figures are illustrative.
Note: Advance tax percentages are cumulative. For example, by September 15th, you should have paid 45% of your total advance tax liability. Therefore, the calculation for September 15th works like this: 45% of ₹12,21,920 = ₹5,49,864. Since you have already paid ₹1,83,288 in June, you will pay ₹3,66,576 (₹5,49,864 - ₹1,83,288) in September.

Can I pay advance tax after due dates?
You can still pay after a due date has passed. There’s no fixed late fee, but interest starts running under two provisions of the law.
- Interest under Section 425 (earlier Section 234C)
It applies when you defer or fall short on a quarterly instalment. The charge is 1% simple interest per month on the shortfall, applied for a fixed three months on the June, September, and December instalments and for one month on the March instalment. A 10-day delay costs the same as a three-month one, so even a small miss carries the full charge.
One relief is built in. Pay at least 12% of the tax due on your returned income by June 15th, and no interest applies on the first instalment; the same holds at the second instalment if you have paid at least 36% by September 15th. But it is a threshold, not a cushion; fall even marginally short and interest runs on the shortfall measured against the full 15% or 45%.
- Interest Under Section 424 (earlier Section 234B)
It kicks in when, by March 31st, your total advance tax paid is less than 90% of your final tax liability for the year. You then pay interest at 1% per month on the unpaid balance from April 1st until the date you clear the outstanding tax.
Both charges carry the same rates and logic they had as Section 234C and Section 234B under the Income Tax Act, 1961, renumbered under the Income Tax Act, 2025, for Tax Year 2026-27.
Advance tax looks simple until capital gains, a bonus, or a new income source complicates the estimate. After using the 1 Finance Advance Tax Calculator, a Qualified Financial Advisor can map your full income picture, work out the right instalments, and fold your tax into a plan that also covers your investments, insurance, and retirement. Getting the estimate right early saves you both interest and the scramble in March.
