Advance Tax: Who Needs to Pay It, When, and How

Most salaried employees never encounter advance tax because their employer manages it through monthly TDS. But for freelancers, business owners, rental income earners, investors with capital gains, or anyone with significant income beyond their salary, advance tax is a quarterly obligation that — if missed — comes with automatic interest penalties.

Understanding advance tax before you hit a large tax bill is far better than understanding it after.

What Is Advance Tax

Advance tax is the mechanism through which the Income Tax Act requires certain taxpayers to pay their tax liability in instalments during the financial year rather than all at once at filing time.

The rationale is practical: the government wants tax revenue as income is earned, not 12–15 months later when you eventually file your return.

Who must pay advance tax: Any individual whose estimated tax liability for the year is ₹10,000 or more — after accounting for TDS that has already been or will be deducted. The statute (Section 404 of the Income-tax Act, 2025) says "₹10,000 or more", so a liability of exactly ₹10,000 already triggers the obligation; you do not need to cross it.

Practically, this means advance tax is relevant for:

• Freelancers and consultants (whose clients may or may not deduct TDS)
• Self-employed individuals and proprietors
• Professionals in private practice (doctors, architects, lawyers)
• Salaried employees with significant additional income (rental, investments, freelancing)
• Investors with large capital gains during the year
• Anyone who gets a large bonus or commission mid-year that wasn't projected

Who is exempt from advance tax: Senior citizens (age 60 or above) who do not have business or professional income are exempt from advance tax. They pay tax only at the time of self-assessment when filing the ITR.

The Quarterly Schedule

The advance tax calendar has four due dates. The cumulative payment by each date must meet the specified percentage of your estimated annual tax liability:

Important note on capital gains: Capital gains that arise after March 15 (i.e., in the last 15 days of the financial year — March 16 to March 31) can be paid by March 31 without triggering Section 234C interest. This is a specific relaxation because capital gains can be difficult to predict and plan for.

Estimating Your Advance Tax Liability

You estimate your annual income across all heads:

Salary income: Your projected annual salary, minus the standard deduction — ₹75,000 under the new regime, ₹50,000 under the old — and, on the old regime, your HRA exemption.

Rental income: Net annual rent received, minus 30% standard deduction (the flat deduction allowed on rental income for maintenance), minus property tax paid.

Interest income: Savings account interest, FD interest, bond interest — total amount expected for the year.

Business or professional income: Expected net profit for the year.

Capital gains: If you've already sold investments during the year and know the gains, include those. Future capital gains are harder to estimate — include them as they arise and adjust later quarters.

From this gross income, subtract applicable deductions under 80C, 80D, 80CCD(1B), 24(b), and others.

Calculate tax on the resulting taxable income using the applicable slab rates (old or new regime).

Subtract TDS already deducted or expected to be deducted — from your employer, from clients, from banks on FD interest.

The result is your advance tax liability. If this is ₹10,000 or more, you pay quarterly.

How to Pay Advance Tax

Advance tax is paid using Challan 280 (same challan as self-assessment tax) through the income tax e-filing portal (incometax.gov.in):

1. Go to e-Pay Tax under the Services menu
2. Choose the Act. The portal asks this first: select "Income Tax Act 1961" for assessment year 2026-27 and earlier, or "Income Tax Act 2025" for tax year 2026-27 onwards
3. Select Income Tax from the tiles that appear
4. Set Type of Payment: "Advance Tax (100)", and the period. Challans under the 2025 Act are filed against a tax year, not an assessment year, so advance tax on FY 2026-27 income goes against Tax Year 2026-27. Tax on FY 2025-26 income still goes against AY 2026-27 under the old Act — the department flags exactly this pair as the thing to get right during the changeover, so that credit lands in the correct year
5. Fill in the amount
6. Pay via net banking, UPI, or debit card

After payment, download and save the Challan 280 receipt — it contains the BSR code and challan serial number that you'll need when filing your ITR.

Advance tax payments appear in Form 26AS under Part C within a few days of payment. Always verify this before the next instalment.

Special Rules for Presumptive Taxation Scheme

Note on section numbers: the Income-tax Act, 2025 (effective 1 April 2026) consolidated Sections 44AD and 44ADA into Section 58 — confirmed against the Income Tax Department's official transition FAQ and the Act's own text. The turnover limits and single-instalment rule below are unchanged.

Individuals opting for the presumptive taxation scheme under Section 44AD (business turnover up to ₹2 crore, or ₹3 crore where cash receipts stay within 5% of turnover) or 44ADA (professional gross receipts up to ₹50 lakh, or ₹75 lakh under the same 5% cash condition) have a different advance tax schedule:

• They must pay 100% of their estimated advance tax liability in a single instalment by March 15
• The quarterly instalment schedule (June, September, December) does not apply to them
• If they miss the March 15 deadline, Section 234B interest applies from April 1

This is different from the regular 4-instalment schedule. Presumptive taxpayers have it simpler (one payment) but must remember it's due by March 15, not March 31.

The Interest Penalties: Sections 234B and 234C

Missing advance tax triggers two types of interest:

Section 234C — Instalment Default: Interest at 1% per month (simple) for each quarter where payment was short.

Calculated as:

• For the June 15 deadline: If cumulative payment is below 12% of total tax (see the tolerance below), interest = 1% × the shortfall against 15% × 3 months
• For the September 15 deadline: If cumulative payment is below 36% of total tax (see the tolerance below), interest = 1% × the shortfall against 45% × 3 months
• For the December 15 deadline: If cumulative payment is less than 75% of total tax, interest = 1% × shortfall × 3 months
• For the March 15 deadline: If cumulative payment is less than 100% of total tax, interest = 1% × shortfall × 1 month

The tolerance most people never hear about. The first two instalments have a statutory cushion built into them. Under Section 425(2) of the Income-tax Act, 2025 — the same relief the 1961 Act carried in the first proviso to Section 234C — you owe no 234C interest for the June instalment if you have paid at least 12% of the year's tax by 15 June, and none for the September instalment if you have paid at least 36% by 15 September. The scheduled targets are still 15% and 45%; the tolerance simply means a small miss on those two dates costs nothing. There is no equivalent for December (75%) or March (100%) — miss those by a rupee and interest runs on the whole shortfall. So the practical rule is: be roughly right in June and September, and exact in December and March.

Section 234B — Underassessment: If total advance tax paid by March 31 is less than 90% of your assessed tax, interest at 1% per month runs from April 1 to the date of payment (self-assessment tax payment or actual filing, whichever is earlier). Be clear about what the interest is charged on: not the 10% you were allowed to miss, but the whole amount by which your advance tax fell short of the assessed tax. The 90% is only the trigger that switches Section 234B on — once it applies, the base is the full shortfall, and if you paid nothing at all it is the entire assessed tax.

Example: Your total tax liability for FY 2026-27 is ₹2,00,000. You paid ₹0 in advance tax (forgot entirely). Self-assessment tax was finally paid on July 31, 2027.

Section 234B: you paid no advance tax, so the shortfall is the whole assessed tax of ₹2,00,000 — not ₹1,80,000. Interest = 1% × ₹2,00,000 × 4 months (April, May, June, July) = ₹8,000.

Section 234C (for each missed quarterly deadline) would add further interest based on the quarterly shortfalls.

The interest rates are not crushing, but they add up — and more importantly, they indicate systematic non-compliance that can attract scrutiny.

Practical Tips for Freelancers and Consultants

Start tracking income quarterly, not annually. Most advance tax errors happen because people don't know their income position until they try to file the return.

For variable income: Be conservative early in the year. Pay slightly more in June to avoid the minimum threshold issue, and adjust in later quarters as your actual income becomes clearer.

Factor in TDS deducted by clients. Many companies deduct 10% TDS (Section 194J — renumbered Section 393 under the Income-tax Act, 2025, effective 1 April 2026, with the same rate) when paying consultants and freelancers. This TDS counts toward advance tax. If all your consulting income has 10% TDS deducted, you may not owe additional advance tax unless your rate is higher than 10%.

Keep digital copies of challans. Store Challan 280 PDFs (with BSR codes and serial numbers) in your financial documents folder. You'll need these when filing your ITR.

Know which filing date is yours. From AY 2026-27 the return deadline split in two: taxpayers with business or professional income who are not subject to audit now file by 31 August, while salaried and other non-business taxpayers stay on 31 July. That extra month is a filing extension, not an advance tax extension — March 15 and the 234B clock from April 1 are untouched by it.

Don't wait for the March 15 deadline to discover you owe a large amount. Review your income position in October (before the December instalment) and again in January (before finalising March). Surprises at filing time usually mean interest has already accrued.

Advance tax is not a punishment — it's simply a pay-as-you-earn mechanism for those whose income isn't captured through employer TDS. Building the quarterly discipline into your financial calendar from the start of your self-employed or multi-income journey is far simpler than catching up after the fact.

Section 234C Interest: A Precise Calculation

Section 234C charges 1% simple interest per month (or part thereof) on the shortfall at each quarterly deadline. The calculation compares what was due by each date against what was actually paid by that date.

Quarterly shortfall thresholds:

The middle column is Section 425(2). If your cumulative payment reaches 12% by 15 June or 36% by 15 September, that instalment attracts no interest at all — the shortfall against the 15% or 45% target is ignored. December and March are unforgiving by comparison.

Working example:

Total tax liability for FY 2026-27: ₹3,00,000.

Kavita paid:

• June: ₹0 (paid nothing)
• September: ₹1,20,000 (cumulative)
• December: ₹2,10,000 (cumulative)
• March: ₹3,00,000 (cumulative)

Section 234C calculation:

June deadline: Required 15% = ₹45,000. Paid ₹0 — below the 12% (₹36,000) tolerance, so the tolerance does not save her. Shortfall: ₹45,000. Interest: 1% × ₹45,000 × 3 months = ₹1,350

September deadline: Required 45% = ₹1,35,000. Paid ₹1,20,000, which is 40% of the year's tax — at or above the 36% (₹1,08,000) tolerance, so Section 425(2) applies and the ₹15,000 shortfall is ignored. Interest: nil

December deadline: Required 75% = ₹2,25,000. Paid ₹2,10,000. No tolerance applies here. Shortfall: ₹15,000. Interest: 1% × ₹15,000 × 3 months = ₹450

March deadline: Required 100% = ₹3,00,000. Paid ₹3,00,000. No shortfall.

Total Section 234C interest: ₹1,350 + ₹450 = ₹1,800

This is relatively small because she caught up quickly, and because the September tolerance absorbed a ₹15,000 miss entirely — the identical ₹15,000 miss in December cost her ₹450. Had she paid nothing until March 15, the interest would be substantially higher.

Salaried Employees: When Advance Tax Becomes Relevant

Most salaried employees never pay advance tax because employer TDS covers their entire liability. But several situations create advance tax obligations:

Scenario 1: Rental income A salaried employee earns ₹15L salary (fully covered by TDS) but also receives ₹3L annual rent from a property. After 30% standard deduction on rental income: ₹2,10,000 net rental income. Tax at 30% = ₹63,000. If this is ₹10,000 or more (it is), advance tax is required on the ₹63,000.

Scenario 2: Large capital gains You sold equity shares in July 2026 for a gain of ₹5,00,000. This is an in-year event not covered by employer TDS. Tax on ₹3,75,000 taxable LTCG (₹5L − ₹1.25L exemption) at the 12.5% rate = ₹46,875, before cess. This triggers advance tax for September and December instalments.

For capital gains arising before March 15: they should have been included in advance tax calculations. For capital gains arising between March 16 and March 31 (last 15 days): payable by March 31 without Section 234C interest — a specific relaxation.

Scenario 3: Freelance income alongside salary Priya earns ₹18L salary (TDS covered) and ₹4L from freelance consulting (clients deduct 10% TDS = ₹40,000). Her total tax on ₹4L freelance income at 30% = ₹1,20,000. After TDS credit of ₹40,000: net tax on freelance = ₹80,000. That is well past ₹10,000, so advance tax is required.

Advance Tax for New Regime Taxpayers

The advance tax calculation mechanics are the same under both old and new regimes — the difference is only in which deductions you apply when estimating your annual tax liability.

New regime advance tax estimate:

• Gross income from all sources
• Less: ₹75,000 standard deduction (salaried)
• Less: 80CCD(2) employer NPS if applicable
• Apply new regime slabs
• Less TDS already deducted/expected
• If balance is ₹10,000 or more: advance tax required

Old regime advance tax estimate:

• Same gross income
• Less standard deduction ₹50,000
• Less HRA exemption
• Less all Chapter VI-A deductions (80C, 80D, 24(b), etc.)
• Apply old regime slabs
• Less TDS
• If balance is ₹10,000 or more: advance tax required

The quarterly payment amounts are the same percentage thresholds regardless of regime.

When TDS from Multiple Sources Reduces Advance Tax

Advance tax liability is net of all TDS that has been or will be deducted in the year. This is important for those with multiple TDS sources:

• Employer TDS (monthly, from salary)
• Bank TDS on FD interest (if interest from a single bank exceeds ₹50,000/year, or ₹1,00,000 for senior citizens — both thresholds raised with effect from 1 April 2025)
• Client TDS on consulting fees (10% under Section 194J)
• Tenant TDS on rent received (if company/HUF tenant pays rent above ₹50,000/month)

All of these count. If a consultant's clients consistently deduct 10% TDS and that equals 90%+ of their total annual tax, there may be no advance tax obligation despite having self-employed income.

Calculation check:

Total estimated annual tax: ₹2,00,000 Expected TDS from all sources: ₹1,85,000 Advance tax payable: ₹2,00,000 − ₹1,85,000 = ₹15,000 (₹10,000 or more → advance tax required)

In this case, advance tax of ₹15,000 should be split across instalments:

• June: 15% = ₹2,250
• September: 45% cumulative = ₹6,750
• December: 75% cumulative = ₹11,250
• March: 100% = ₹15,000

Tax on Capital Gains and Advance Tax Timing

The most common advance tax failure for investors: a large equity redemption or property sale in July creates a substantial capital gains tax liability. The taxpayer doesn't pay advance tax in September or December, and pays only at ITR filing time the following year.

Result: Section 234C interest for September (3 months × 1% × shortfall) and December (3 months × 1%) and Section 234B (April to the payment date × 1% × shortfall).

For a ₹1 lakh capital gains tax liability:

• 234C for September: ₹3,000
• 234C for December: ₹3,000
• 234B: ₹4,000 (April–July = 4 months)
• Total interest: ₹10,000

10% of the tax in interest penalties — not catastrophic but entirely avoidable. The discipline is simple: when you realise a large gain in Q1 or Q2, note the approximate tax and pay advance tax in the next quarterly instalment.

For a precise estimate on a complex income mix, a CA's number beats a rough one.
