Advance Tax Due Dec 15: How to Pay 75% on ₹8 Lakh Income

If you're a freelancer, consultant, or someone who earns a chunk of income outside a regular salary, December 15 should be circled in red on your calendar. That's the deadline for your third advance tax instalment — the one where the taxman expects you to have paid 75% of your total annual tax liability already. Miss it, and the Income Tax Department quietly starts clocking penal interest under Sections 234B and 234C at 1% per month, compounded on your shortfall.

Here's a number that surprises most people: on an ₹8 lakh professional income with roughly ₹30,000+ of tax due, delaying the December instalment by even a quarter can cost you ₹600–₹900 in pure interest — money that buys you absolutely nothing. Multiply that across all four instalments and sloppy planning easily burns a four-figure hole. The irritating part? This is the most avoidable penalty in the entire tax code.

In this guide I'll walk you through exactly how to calculate and complete your advance tax payment December 2026 instalment, with a fully worked example on ₹8 lakh income, the precise cumulative percentages, how 234B and 234C interest actually gets levied, and a step-by-step walkthrough of paying on the e-filing portal. No jargon, no fluff — just what you need to pay the right amount on time.

Key Takeaways

• December 15 = 75% cumulative. By this date you must have deposited at least 75% of your estimated total tax for the financial year.
• Who must pay: Anyone whose total tax liability for the year is ₹10,000 or more after TDS — freelancers, consultants, landlords, traders, and investors with capital gains.
• 234C is the "missed instalment" interest (1%/month for 3 months on each shortfall); 234B kicks in if you pay less than 90% of total tax by year-end.
• Presumptive taxpayers (44AD/44ADA) get a break — they pay 100% in a single shot by March 15.
• Capital gains and lottery income are exempt from 234C for the instalments before they arose — but you must pay in the very next instalment.
• Estimate your tax first using our Income Tax Calculator before you pay a rupee.

What is advance tax and who actually has to pay it?

Advance tax is simply the "pay-as-you-earn" principle applied to income tax. Instead of paying your entire tax bill in one lump sum when you file your return, the law expects you to pay it in instalments through the year, as you earn.

You are liable to pay advance tax if your estimated total tax liability for the year is ₹10,000 or more, after deducting any TDS or TCS already credited to you. This single threshold catches a lot of people:

• Freelancers and consultants billing clients who don't deduct TDS, or deduct only 10% under 194J.
• Business owners and traders whose income isn't tax-deducted at source.
• Investors who book sizeable capital gains, dividends, or interest income.
• Landlords earning rental income above the basic exemption.
• Salaried employees with large side income — your employer deducts TDS on salary, but not on your YouTube or trading profits.

The one big exemption: A resident senior citizen (60+) who has no income from business or profession is not required to pay advance tax at all. They can settle everything as self-assessment tax.

The four instalment deadlines and cumulative percentages

For most taxpayers (not under presumptive schemes), advance tax is paid in four instalments. Note that each percentage is cumulative — it includes what you've already paid.

Due Date	Cumulative % of Total Tax Payable	Instalment This Quarter
15 June	15%	15%
15 September	45%	30%
15 December	75%	30%
15 March	100%	25%

So by December 15 you should have cumulatively deposited 75% of your total tax. If you've been paying diligently since June, this instalment is just the extra 30%. If you skipped the earlier ones, you need to catch up to the full 75% now (and you'll owe some 234C interest for the earlier misses — more on that below).

How to calculate your advance tax payment December 2026 on ₹8 lakh income

Let's make this concrete with a realistic case. Meet Priya, a freelance graphic designer in Pune. Her situation for FY 2025-26:

• Gross professional receipts: ₹8,00,000
• She opts for the new tax regime (default from FY 2023-24 onwards).
• She does not use the presumptive 44ADA scheme this year because she wants to claim actual expenses.
• Business expenses (laptop, software, internet, rent share): ₹1,50,000
• One client has already deducted TDS of ₹20,000 under Section 194J.

Step 1: Compute net taxable income

Net professional income = ₹8,00,000 − ₹1,50,000 = ₹6,50,000. Under the new regime there's no Chapter VI-A deductions like 80C, but she does get the standard deduction only on salary — as a pure professional she doesn't. So taxable income stays ₹6,50,000.

Step 2: Apply the new regime slabs (FY 2025-26)

The new regime slabs for FY 2025-26 (AY 2026-27) are:

• Up to ₹4,00,000 — Nil
• ₹4,00,001 to ₹8,00,000 — 5%
• ₹8,00,001 to ₹12,00,000 — 10%
• ₹12,00,001 to ₹16,00,000 — 15%
• and so on up to 30% above ₹24 lakh

On taxable income of ₹6,50,000:

• First ₹4,00,000 → ₹0
• Next ₹2,50,000 (from ₹4L to ₹6.5L) @ 5% → ₹12,500

Basic tax = ₹12,500. Now, the Section 87A rebate under the new regime makes income up to ₹12,00,000 effectively tax-free. Priya's taxable income is ₹6.5 lakh, well under ₹12 lakh, so her rebate wipes out the entire ₹12,500.

Priya's net tax liability = ₹0. She has no advance tax to pay, and in fact can claim a refund of her ₹20,000 TDS when she files. That's the power of the revamped new regime for middle incomes.

Step 2 (alternative): what if her income were higher?

The ₹8L example is deliberately eye-opening — many professionals at this level now owe nothing. To show the actual advance-tax mechanics, let's bump Priya's net taxable income to ₹14,00,000 (say she had fewer expenses and more clients).

• Up to ₹4,00,000 → ₹0
• ₹4,00,001–₹8,00,000 @ 5% → ₹20,000
• ₹8,00,001–₹12,00,000 @ 10% → ₹40,000
• ₹12,00,001–₹14,00,000 @ 15% → ₹30,000

Basic tax = ₹90,000. Add 4% health & education cess = ₹3,600. Total tax = ₹93,600. Here the 87A rebate doesn't apply (income above ₹12 lakh).

Step 3: Deduct TDS already paid

Net advance tax base = ₹93,600 − ₹20,000 TDS = ₹73,600. Since this exceeds ₹10,000, Priya must pay advance tax.

Step 4: Compute the December 15 (75%) obligation

Cumulative 75% of ₹73,600 = ₹55,200.

If Priya had already paid 15% (₹11,040) in June and reached 45% (₹33,120) by September, her December instalment is simply the gap:

₹55,200 − ₹33,120 already paid = ₹22,080 due now.

If she skipped June and September entirely, she must pay the full ₹55,200 by December 15 to be compliant going forward — and she'll owe a little 234C interest for the earlier shortfalls. Run your own figures through our Income Tax Calculator and the Salary In-Hand Calculator if you have mixed salary-plus-freelance income.

How is 234B and 234C interest actually calculated?

This is where people get stung. Two separate sections apply, and they can both hit the same return.

Section 234C — interest for deferment of instalments

234C penalises you for not meeting each quarterly milestone. The interest is 1% per month for 3 months on the shortfall at the June, September, and December checkpoints, and 1% for 1 month on the March shortfall.

Using Priya's ₹73,600 figure, suppose by December 15 she had paid only ₹40,000 instead of the required ₹55,200. Shortfall = ₹15,200.

234C interest on the December instalment = ₹15,200 × 1% × 3 months = ₹456. (The portal rounds the shortfall down to the nearest ₹100, so technically on ₹15,200 it's ₹456.)

Important relief: 234C gives a cushion. For the June and September instalments you're spared the interest if you've paid at least 12% and 36% respectively (instead of the full 15% and 45%). This is the law's acknowledgment that income is hard to estimate early in the year.

Section 234B — interest for default in payment of advance tax

234B is the bigger stick. It applies if, by March 31 (end of the financial year), you have paid less than 90% of your total tax via advance tax and TDS. The interest is 1% per month on the entire shortfall, running from April 1 until you actually pay (typically when you file your return).

Say Priya pays nothing all year and settles ₹73,600 only when she files in July. She's missed 90%, so 234B runs for roughly 4 months (April–July) = ₹73,600 × 1% × 4 = ₹2,944, plus the 234C already accrued. The lesson: the longer you delay past March 31, the more 234B compounds.

Common mistake: People think TDS "handles" their tax so they ignore advance tax. If you have significant non-salary income — capital gains, freelance fees, rent — TDS rarely covers 90% of your bill. Reconcile your Form 26AS / AIS before each instalment to see exactly how much TDS is credited, then pay the gap. Guessing is what triggers both 234B and 234C.

How do capital gains and sudden income affect your December instalment?

This trips up investors constantly. You can't be expected to predict in June that you'll sell shares for a ₹5 lakh gain in November. So the law offers relief: for capital gains, dividend income, lottery/gambling winnings, and first-year presumptive business income, no 234C interest is charged for the instalments that fell before that income arose — provided you pay the tax on it in the next instalment (or by March 31 if it arises after March 15).

Example: You book a ₹2 lakh equity LTCG in October. The tax on it must be included in your December 15 instalment. If you do, you avoid 234C on it for the earlier June/September milestones. If equity trading or crypto is a meaningful chunk of your income, read our deep-dive on how crypto profits are taxed in India so you don't under-provide.

Similarly, if you've bought a property above ₹50 lakh, remember the buyer-side obligations in our guide to TDS on property purchase — these interact with your overall tax position.

Old regime vs new regime: which lowers your advance tax?

Since advance tax is just a function of your final liability, picking the right regime directly reduces how much you deposit. Here's a comparison across three professional income levels (net taxable income, FY 2025-26, no 80C claimed for simplicity in new regime):

Taxable Income	New Regime Tax (incl. cess)	Old Regime Tax (incl. cess, ₹1.5L 80C)	Better Choice
₹8,00,000	₹0 (87A rebate)	₹49,400	New Regime
₹12,00,000	₹0 (87A rebate)	₹1,19,600	New Regime
₹18,00,000	₹1,95,000 approx.	₹2,96,400 approx.	New Regime

Figures are illustrative and assume no large deductions beyond ₹1.5L 80C in the old regime. Your actual numbers depend on home loan interest, HRA, NPS, etc.

For most professionals without heavy deductions, the new regime now wins comfortably — and that lowers your advance tax burden to near zero at middle incomes. But if you have a home loan with large interest (check your figures with the Home Loan EMI Calculator), substantial HRA (see the HRA Exemption Calculator), or max out 80C and NPS, the old regime can still edge ahead. Model both before you commit, and read our breakdown of the changes under the new Income Tax Act 2025 that affect your salary.

Step-by-step: how to pay advance tax on the e-filing portal

Paying is genuinely a 5-minute job once you know the clicks. Here's the full walkthrough using the Income Tax Department's e-Pay Tax facility:

1. Go to the Income Tax e-filing portal (incometax.gov.in) and click e-Pay Tax under Quick Links. You can pay with or without logging in (PAN + OTP based).
2. Enter your PAN and mobile number, verify with the OTP.
3. Select "Income Tax" as the tax category and click Proceed.
4. Choose Assessment Year 2026-27 for FY 2025-26. This is the single most common error — people pick the wrong AY and the payment lands in limbo.
5. Under "Type of Payment", select "Advance Tax (100)". (Code 100 = advance tax; 300 = self-assessment; 400 = regular assessment. Don't mix them up.)
6. Enter the tax amount under the correct heads — typically the full figure goes under "Tax"; cess is auto-handled or you split it under the relevant columns.
7. Pick your payment mode: Net Banking, Debit Card, NEFT/RTGS, UPI, or over-the-counter at an authorised bank.
8. Complete the payment and download the Challan (CRN) receipt. Save the BSR code, challan serial number, and date — you'll need these when filing your ITR.

Pro tip: After paying, wait 2–3 working days and check your AIS / Form 26AS to confirm the challan is reflected against your PAN. If it isn't showing by the time you file, you can still enter the challan details manually in the ITR, but a visible 26AS entry saves you a mismatch notice. Set a reminder for the next instalment the moment this one clears.

Advance tax for presumptive taxpayers (44AD / 44ADA)

If you're a small professional or business under the presumptive taxation scheme, you get a major simplification. Instead of four instalments, you pay your entire advance tax in one shot by March 15.

• 44ADA (professionals — doctors, lawyers, architects, consultants, etc.): declare 50% of gross receipts as income, available if receipts are up to ₹50 lakh (₹75 lakh if cash receipts are under 5%).
• 44AD (small businesses): declare 8% of turnover (6% for digital receipts) as income, up to ₹2 crore / ₹3 crore turnover limits.

So if Priya had chosen 44ADA, she wouldn't worry about December 15 at all — she'd pay by March 15. But note: once you pick presumptive, declaring lower profit than the presumptive rate for 5 years locks you out of the scheme and triggers audit requirements. Weigh it carefully.

A quick note on reinvesting what you save

Here's the mindset shift that separates good planners from the rest: the point of paying advance tax on time isn't just avoiding ₹456 of interest — it's about never giving the taxman an interest-free loan or paying penalties that could instead compound in your own portfolio.

Say you avoid ₹3,000 of 234B/234C interest every year and instead invest it. ₹3,000/year into an equity SIP at 12% CAGR over 20 years grows to roughly ₹2.7 lakh. Not life-changing, but it's free money from simply being organised. Plug your own numbers into our SIP Calculator or the Compound Interest Calculator to see how small savings snowball. If you prefer safer parking, compare returns on the FD Calculator and PPF Calculator.

Frequently Asked Questions

What is the advance tax due date in December 2026?

The third advance tax instalment is due on December 15. By this date you must have cumulatively paid 75% of your estimated total tax liability for the financial year. Paying on or before this date keeps you clear of Section 234C interest for the December milestone.

Do freelancers earning ₹8 lakh have to pay advance tax?

Only if their net tax liability after TDS is ₹10,000 or more. Under the new regime for FY 2025-26, income up to ₹12 lakh often attracts zero tax thanks to the Section 87A rebate, so an ₹8 lakh professional with reasonable expenses may owe nothing — but you must still calculate to be sure.

What happens if I miss the December 15 advance tax instalment?

You'll be charged 1% per month under Section 234C for three months on the shortfall. If your total advance tax plus TDS ends up below 90% of your liability by March 31, Section 234B adds another 1% per month until you clear the dues when filing your return.

Can I pay the whole advance tax in one go by March 15?

Only taxpayers under the presumptive schemes (Sections 44AD and 44ADA) are allowed to pay 100% by March 15 in a single instalment. Everyone else must follow the four-instalment schedule, or they'll incur 234C interest for the missed quarters.

Is advance tax applicable on capital gains?

Yes, but with relief. Since gains can't be predicted in advance, you're spared 234C interest on them for instalments falling before the gain arose — as long as you include that tax in the very next instalment or pay by March 31 if it arose after March 15.

How do senior citizens handle advance tax?

Resident senior citizens (aged 60 and above) with no income from business or profession are fully exempt from advance tax. They can p
