How advance tax instalments are calculated
Advance tax = Total tax − TDS deducted
Q1 (by 15 Jun) = 15% of advance tax
Q2 (by 15 Sep) = 45% cumulative − Q1 paid
Q3 (by 15 Dec) = 75% cumulative − Q1+Q2 paid
Q4 (by 15 Mar) = 100% cumulative − Q1+Q2+Q3 paid
Example: Total advance tax = ₹2,00,000
Q1: 15% × ₹2L = ₹30,000 (by 15 June)
Q2: 45% × ₹2L − ₹30,000 = ₹60,000 (by 15 Sep)
Q3: 75% × ₹2L − ₹90,000 = ₹60,000 (by 15 Dec)
Q4: 100% × ₹2L − ₹1,50,000 = ₹50,000 (by 15 Mar)
What Is an Advance Tax Calculator?
An advance tax calculator estimates how much income tax you must pay in instalments during the financial year itself, rather than as a single payment after the year ends. It takes your estimated annual income, regime (new or old), deductions, and any TDS already deducted, then computes your total tax liability for FY 2025-26 / FY 2026-27 and splits the remaining balance into the four statutory instalments due on 15 June, 15 September, 15 December, and 15 March under Section 208 of the Income Tax Act.
Beyond the instalment amounts, this calculator also estimates the interest penalty under Section 234C if you fall short of the required cumulative percentage by any due date - helping freelancers, traders, business owners, and anyone with non-salary income avoid unnecessary interest charges.
Updated Tax Slabs for FY 2025-26 & FY 2026-27 (New Regime)
Since Budget 2025, the new tax regime slabs were significantly revised - the basic exemption limit rose to ₹4 lakh and the Section 87A rebate increased to ₹60,000, making taxable income up to ₹12 lakh effectively tax-free. Budget 2026 made no further changes, so these slabs apply for both FY 2025-26 (AY 2026-27) and FY 2026-27 (AY 2027-28). This calculator uses the slabs below.
| Taxable Income Slab | New Regime Rate | Old Regime Rate (individual) |
|---|---|---|
| ₹0 – ₹2.5 lakh | 0% | 0% |
| ₹2.5L – ₹4L | 0% | 5% |
| ₹4L – ₹5L | 5% | 5% |
| ₹5L – ₹8L | 5% | 20% |
| ₹8L – ₹10L | 10% | 20% |
| ₹10L – ₹12L | 10% | 30% |
| ₹12L – ₹16L | 15% | 30% |
| ₹16L – ₹20L | 20% | 30% |
| ₹20L – ₹24L | 25% | 30% |
| Above ₹24L | 30% | 30% |
Key takeaway: ₹12 lakh tax-free under the new regime
Because the Section 87A rebate (up to ₹60,000) fully cancels out the tax on taxable income up to ₹12 lakh, anyone with taxable income at or below this threshold pays zero income tax under the new regime. For salaried employees, the ₹75,000 standard deduction pushes the effective tax-free gross salary to ₹12.75 lakh. This calculator applies these rules automatically when you select the new regime.

Frequently asked questions about advance tax
What is the income tax slab for FY 2026-27?▼
Under the new tax regime for FY 2026-27 (unchanged from FY 2025-26 per Budget 2026): income up to ₹4 lakh is nil, ₹4-8 lakh at 5%, ₹8-12 lakh at 10%, ₹12-16 lakh at 15%, ₹16-20 lakh at 20%, ₹20-24 lakh at 25%, and above ₹24 lakh at 30%. Combined with the Section 87A rebate of ₹60,000, taxable income up to ₹12 lakh attracts zero tax. For salaried employees, after the ₹75,000 standard deduction, gross salary up to ₹12.75 lakh is effectively tax-free. The old regime slabs remain unchanged.
Do salaried employees need to pay advance tax?▼
Usually no - because your employer deducts TDS on your salary monthly, which counts as advance tax. However, if you have additional income beyond salary - such as rental income, freelance income, capital gains from stocks or crypto, interest income, or business income - and the total tax on that additional income exceeds ₹10,000 after TDS credit, you must pay advance tax on those earnings quarterly.
What if I underestimate my income and pay less advance tax?▼
If you pay less than 90% of your actual tax liability as advance tax by March 31, you'll owe interest under Section 234B at 1% per month from April 1 until you pay. Additionally, if any instalment is short (e.g., less than 15% by June 15), Section 234C interest applies at 1% per month for 3 months on that shortfall. The IT system calculates this automatically when you file your ITR - you can't avoid it, but you can minimize it by revising your advance tax upward when your income estimate changes.
Can I revise my advance tax payment if my income changes?▼
Yes - advance tax is based on estimated income, and you can revise your estimate any time during the year. If your income increases mid-year (e.g., you get a big freelance project in October), you should increase your Q3 and Q4 instalments accordingly. If your income decreases (e.g., you lose a client), you can reduce future instalments. There's no penalty for changing your estimate - only for consistently paying less than the required cumulative percentages.
What is the difference between advance tax and self-assessment tax?▼
Advance tax is paid during the financial year in 4 instalments, based on estimated income. Self-assessment tax is the balance tax you pay after the year ends - when you file your ITR - if your actual tax liability turns out to be higher than the advance tax + TDS you already paid. Both use Challan 280 for payment, but the payment type selected differs: '100' for advance tax and '300' for self-assessment tax.
Do traders who make profits from F&O or intraday trading need to pay advance tax?▼
Yes - F&O trading income is treated as business income (not capital gains), and intraday equity trading is also speculative business income. Both are subject to advance tax. Since trading profits are volatile and hard to predict quarterly, many traders estimate conservatively for Q1/Q2/Q3 and make a larger Q4 payment by March 15 after the year's P&L is clearer. If you're in F&O, paying at least 75% of your estimated annual tax by December 15 is the minimum to avoid significant 234C interest.
What happens if I miss the 15 March deadline (Q4)?▼
Missing the Q4 advance tax deadline (March 15) has two consequences: (1) Section 234C interest at 1% per month for 3 months on the shortfall amount, and (2) if your total advance tax paid falls below 90% of your total liability, Section 234B interest kicks in from April 1 onwards until you pay. The Q4 shortfall is added to your self-assessment tax due when filing the ITR. You can still pay it as self-assessment tax before filing - but the interest under 234B continues to accrue.
Is advance tax applicable to presumptive taxation scheme taxpayers?▼
Yes, but with a simplified rule. Small businesses and professionals under the Presumptive Taxation Scheme (Section 44AD and 44ADA) can pay their entire advance tax liability in a single instalment by March 15 instead of the normal 4-instalment schedule. This is the key advantage of the presumptive scheme - no quarterly tracking needed. However, if they miss the March 15 deadline, both 234B and 234C interest apply on the full outstanding amount.
How do I claim TDS credit against advance tax?▼
TDS deducted by your employer, banks, clients, and others throughout the year automatically appears in your Form 26AS and Annual Information Statement (AIS). When computing advance tax, subtract your expected total TDS for the year from your total tax liability - the difference is your advance tax obligation. When filing your ITR, the TDS credit is automatically applied and any excess TDS becomes a refund. Always reconcile your Form 26AS before filing to ensure all TDS is correctly credited.
If my taxable income is below ₹12 lakh under the new regime, do I still need to pay advance tax?▼
If your taxable income is at or below ₹12 lakh and you've opted for the new regime, your tax liability after the Section 87A rebate is zero - so advance tax does not apply, regardless of TDS already deducted (any excess TDS becomes a refund when you file your ITR). However, if you have income types that push your taxable income above ₹12 lakh (for example, large capital gains taxed at special rates which are not eligible for the 87A rebate), advance tax may still apply on that portion.
