Advance Tax 2026: Due Dates, Calculation, and How to Avoid Penalties

Meera is a freelance graphic designer in Mumbai. She earned 22 lakh in FY 2024-25 and forgot about advance tax entirely. When she filed her ITR, she owed 1.8 lakh in tax plus 16,200 in interest penalties under sections 234B and 234C. That penalty was completely avoidable.

Advance tax is simply paying your income tax in installments during the year instead of one lump sum at filing time. If your tax liability exceeds Rs 10,000, the government expects you to pay as you earn.

Who Needs to Pay Advance Tax?

The rule is simple: if your total tax liability for the year, after subtracting all TDS deducted by others, exceeds Rs 10,000, you must pay advance tax.

This typically includes: freelancers and consultants (clients deduct 10% TDS on payments above 30,000, but actual tax rate might be 20-30%). Business owners. People who sold property or shares with significant capital gains. People with rental income where TDS was not deducted. People with substantial FD interest (bank deducts 10% TDS, but your slab rate might be 30%).

Salaried employees usually do not need to worry because their employer deducts TDS each month based on estimated annual income. But if you have side income from freelancing, rent, or investments, the TDS from salary alone will not cover it.

Senior citizens (60+) without business or professional income are exempt. They can settle their tax when filing the return.

The Four Due Dates

Due Date	Cumulative % of Total Tax	Installment %
15 June 2025	15%	15%
15 September 2025	45%	30%
15 December 2025	75%	30%
15 March 2026	100%	25%

If your estimated total tax for the year is 2 lakh, you need to pay 30,000 by June 15, 60,000 more by September 15 (total 90,000), 60,000 more by December 15 (total 1,50,000), and 50,000 by March 15 (total 2,00,000).

For businesses under presumptive taxation (Section 44AD for business, 44ADA for professionals), only one payment by 15 March is required. This is a significant simplification for freelancers opting for presumptive scheme.

How to Calculate Your Advance Tax

Step 1: Estimate your total income for the year. Include all sources: freelance fees, business profit, salary, rental income, capital gains, interest income.

Step 2: Calculate tax on total income using the applicable slab rates (old or new regime). Use our income tax calculator for this.

Step 3: Subtract TDS already deducted or expected to be deducted. Check Form 26AS or AIS on the income tax portal for TDS credits.

Step 4: The remaining amount is your advance tax liability. Divide it according to the quarterly schedule above.

Example: Meera estimates 22 lakh freelance income. Under presumptive taxation (44ADA), 50% is deemed profit = 11 lakh. Tax on 11 lakh (new regime): after 75K standard deduction, taxable = 10,25,000. Tax = 20,000 + 22,500 = 42,500. Cess: 1,700. Total: 44,200. Clients deduct 10% TDS on payments = roughly 2,20,000. TDS far exceeds tax liability, so Meera actually does not need to pay advance tax. She will get a refund.

But if Meera does not opt for presumptive taxation, her entire 22 lakh is income (after expenses). Tax on 22 lakh (new regime): after standard deduction, taxable 21,25,000. Tax = 20,000 + 40,000 + 60,000 + 80,000 + 31,250 = 2,31,250. Cess: 9,250. Total: 2,40,500. TDS = 2,20,000. Remaining: 20,500. Since this exceeds 10,000, she needs to pay advance tax.

Section 234B: Penalty for Not Paying at All

If you paid less than 90% of your total assessed tax as advance tax + TDS by March 31, Section 234B kicks in. The interest is 1% per month (simple interest) on the shortfall, calculated from April 1 until the date of actual payment or assessment.

Example: Total tax assessed = 3,00,000. TDS + advance tax paid by March 31 = 2,50,000 (83.3%, which is below 90%). Shortfall for 234B = 3,00,000 - 2,50,000 = 50,000. If you file in July (4 months from April): 50,000 x 1% x 4 = Rs 2,000 interest.

Part of a month is counted as a full month. So if you pay on April 15, that counts as one full month.

Section 234C: Penalty for Missing Quarterly Deadlines

Even if you pay the full advance tax by March 15, you owe 234C interest if you underpaid in any quarter. The calculation:

If advance tax paid by June 15 is less than 12% of assessed tax (not 15%, there is a 3% buffer): 1% per month on the shortfall for 3 months.

If cumulative payment by September 15 is less than 36% of assessed tax: 1% per month on the shortfall for 3 months.

If cumulative payment by December 15 is less than 75% of assessed tax: 1% per month on the shortfall for 3 months.

If cumulative payment by March 15 is less than 100%: 1% per month on shortfall for 1 month.

The interest amounts are small individually, but they add up. On a 5 lakh tax liability, missing all four deadlines could cost 15,000-20,000 in combined 234B and 234C interest.

How to Pay: Challan 280 Step by Step

Step 1: Go to the e-filing portal (eportal.incometax.gov.in) and navigate to "e-Pay Tax."

Step 2: Enter your PAN. The system will auto-populate your name and details.

Step 3: Select "Income Tax" as the tax type and "Advance Tax (100)" as the payment type.

Step 4: Select the assessment year. For FY 2025-26 income, the assessment year is 2026-27.

Step 5: Enter the amount. Break it into CGST and cess if prompted, or just the total amount.

Step 6: Choose payment method - net banking, debit card, UPI, or at designated bank branches. Net banking is fastest. HDFC, SBI, ICICI, Axis all support online tax payment.

Step 7: Complete payment and save the challan receipt (BSR code, challan serial number, date). You need these when filing your ITR.

The entire process takes 10 minutes. Set calendar reminders for June 10, September 10, December 10, and March 10 (5 days before each deadline as buffer).

Advance Tax for Capital Gains

Here is a tricky situation. You sold shares in October and made 5 lakh in LTCG. How do you pay advance tax on this?

Capital gains are taxed in the quarter they arise. So if you realized gains in October (Q3), you include them in your December 15 advance tax payment. You do not need to retroactively adjust June and September payments.

LTCG on equity above 1.25 lakh is taxed at 12.5%. So 5 lakh LTCG: tax on (5,00,000 - 1,25,000) = 3,75,000 at 12.5% = 46,875. Add this to your December advance tax installment.

Use our capital gains calculator to compute your tax on stock sales and property transactions.

The Presumptive Taxation Shortcut

If you are a freelancer or professional earning under 75 lakh (increased from 50 lakh in Budget 2023, provided digital receipts are 95%+ of total), Section 44ADA lets you declare 50% of gross receipts as profit. No need to maintain books of accounts. No audit required. And advance tax is payable in a single installment by March 15.

This is a massive simplification. A freelancer earning 50 lakh declares 25 lakh as profit, pays tax on that, makes one advance tax payment by March 15, and files ITR-4. Done.

The downside: if your actual expenses exceed 50% of receipts (rent for office, equipment, software, travel), you might be better off under regular taxation where you deduct actual expenses. Run both scenarios using our income tax calculator.

Common Mistakes

Estimating too low to save cash flow: Some people deliberately underestimate income to defer tax payments. The 234C penalty is small (1% per month), so they treat it as a cheap loan. This is technically fine but gets flagged if the pattern repeats. The tax department can issue a notice.

Forgetting to account for TDS changes: If a client stops paying you mid-year, your TDS estimate drops but income might not. Recalculate advance tax each quarter.

Not claiming TDS credits: Check Form 26AS quarterly. Sometimes clients deduct TDS but do not deposit it with the government. You will not get credit until they do. Follow up.

Paying under wrong assessment year: FY 2025-26 income is AY 2026-27. Getting this wrong means your payment sits in the wrong account and shows as unpaid for the correct year.

My Recommendation

If you are a freelancer, opt for presumptive taxation (44ADA) and make one payment by March 15. Simple, compliant, and you avoid quarterly tracking.

If you are salaried with side income, declare the side income to your employer (they can adjust TDS) or pay the differential as advance tax quarterly. The June 15 payment is hardest to estimate since the year has barely started. Be conservative - overpayment gets refunded with 6% interest.

Set up a separate bank account or recurring deposit for tax. Every time you receive freelance income, move 30% to this account immediately. When the advance tax date arrives, the money is already there.
