Advance Tax & Undisclosed Income

Advance tax is the requirement to pay income tax in installments during the year — rather than all at once when filing your return. Individuals, businesses, and professionals with tax liability above ₹10,000 for the year must pay advance tax. Undisclosed income — income earned but not reported in past returns — carries serious legal and financial risk if discovered during scrutiny.

Service Overview

Pay Tax on Time, Disclose Proactively, Sleep Peacefully

The income tax law requires advance tax payments across four quarterly installments — June 15, September 15, December 15, and March 15. Failure to pay advance tax or underpayment results in interest under Sections 234B and 234C — which is charged even if you file the ITR on time. For taxpayers who have undisclosed income from past years — unaccounted cash, unrecorded business income, or foreign assets — proactive voluntary disclosure is significantly better than waiting for a department inquiry. We assist with advance tax computation, timely payment planning, and where needed, structuring compliant disclosures of previously unreported income.

Critical: Advance tax must be paid in four quarterly installments — June 15, September 15, December 15, and March 15. Interest under Section 234C runs at 1% per month for each installment shortfall, and Section 234B applies from April 1 if total advance tax paid is below 90% of the final liability. These interests are non-waivable even with a valid reason.

Advance Tax Computation

Four quarterly installments

Advance tax is based on estimated total income for the year. We compute estimated income, applicable deductions, TDS credits, and the net advance tax due for each quarter — factoring in business growth, capital gains, and other income streams.

Interest under 234B & 234C

Understand and minimize interest

Section 234B charges interest if advance tax paid is less than 90% of final liability. Section 234C charges interest for each quarter where installment is below the required percentage. We compute these accurately and identify legitimate ways to reduce them.

Voluntary Compliance Advisory

Disclose before the department discovers

Taxpayers with undisclosed income — from business, investments, or inherited cash — can significantly reduce their risk by proactively filing updated returns (ITR-U under Section 139(8A)) with the additional income and paying tax with the applicable surcharge.

Updated Return (ITR-U) Filing

Section 139(8A) — 2 year window

Updated returns can be filed within 2 years of the end of the relevant assessment year. Filing ITR-U with additional income (and 25%–50% surcharge on additional tax) closes the risk of future notices for that year's income.

Eligibility Criteria

Who Must Pay Advance Tax?

Advance tax applies broadly — most earning individuals and businesses are covered.

Tax Liability Above ₹10,000

Any taxpayer whose estimated income tax liability (after TDS credit) for the year exceeds ₹10,000 is required to pay advance tax in quarterly installments.

Business Income Earners

Businesses, professionals, and freelancers who do not have sufficient TDS deducted on their income must pay advance tax. Most business income comes without TDS — making advance tax mandatory.

Capital Gains Earners

Capital gains (from shares, mutual funds, or property) earned during the year are included in advance tax computation from the quarter in which the gain arises.

Senior Citizens with Business Income

Senior citizens (above 60 years) with business income are liable for advance tax. Senior citizens with only pension and interest income (no business income) are exempt from advance tax.

Key Benefits

Why Advance Tax and Voluntary Disclosure Planning Matters

Proactive compliance costs far less than reactive penalties and investigations.

Avoid 234B & 234C Interest

Interest under Sections 234B and 234C runs at 1% per month — on shortfalls that compound across multiple quarters. Accurate advance tax planning eliminates these costs.

Prevent Surprise March Liability

Without advance tax planning, the full year's tax liability becomes payable at once in March — straining business cash flow and potentially requiring high-cost emergency borrowing.

Updated Return Window

Filing ITR-U with undisclosed income carries a 25% surcharge (if filed in Year 1) or 50% surcharge (Year 2) on the additional tax. This is vastly better than a search/survey, which triggers 60% undisclosed income tax plus 25% surcharge + penalties.

Avoid Prosecution Risk

Deliberate concealment of income can lead to prosecution under Section 276C — with imprisonment. Voluntary disclosure with ITR-U or during survey proceedings significantly reduces prosecution risk.

Clean Tax Record

A history of timely advance tax payments and clean ITR filings strengthens your tax profile — important for loan applications, government tenders, and visa processing.

Accurate TDS Credit Matching

Advance tax computation accounts for all TDS deducted on salary, interest, rent, and professional fees — ensuring you pay the exact net balance without overpaying.

Step 1 of 6

Estimate Total Annual Income

Project income across all heads — business profit, salary, capital gains, interest, rental income — for the financial year. Use actual year-to-date figures plus conservative projections.

Step 2 of 6

Identify All Deductions

Apply all applicable deductions — 80C investments, 80D health insurance, home loan interest, business expenses — to arrive at estimated taxable income.

Step 3 of 6

Compute TDS Credits

Subtract expected TDS — from salary employer, bank TDS on FD interest, TDS on rental income — to arrive at net advance tax payable for the year.

Step 4 of 6

Calculate Quarterly Installments

Split the annual advance tax across the four quarters — 15% by June 15, 45% by September 15, 75% by December 15, 100% by March 15 (for non-presumptive taxpayers).

Step 5 of 6

Pay via Challan 280

Pay advance tax through Challan 280 (Income Tax on Companies / Other than Companies) online via income tax portal — selecting the correct Assessment Year and payment type.

Step 6 of 6 Final Step

Update Computation Mid-Year

Revisit income estimates after Q2 and Q3 — if income has changed significantly (large capital gain, new contract, etc.), recompute and adjust the remaining installments.

Document Checklist

Information Needed for Advance Tax Computation

Advance tax is estimated — actual computation requires financial data available at the start of each quarter.

Income Data

Business Profit Estimate (YTD)

Actual P&L for the period from April to current date — as the basis for projecting full-year business income.

Salary Slips

Recent salary slips and Form 16 (if mid-year change) — for projecting annual salary income and employer TDS.

Capital Gain Statements

Broker capital gains reports, property sale agreements — for any realized capital gains to include in advance tax.

Presumptive taxation scheme taxpayers (Section 44AD, 44ADA) pay 100% of advance tax in a single installment by March 15 — they are not required to pay quarterly installments like regular taxpayers.

Post Registration

After Each Advance Tax Payment

Track payments and adjust forward estimates throughout the year.

After each payment

Verify Challan in Form 26AS

After paying advance tax, verify that the challan appears in your Form 26AS within 3–5 working days. If not reflected, raise a challan correction request before filing the ITR.

December 15

Revise Estimates in Q3

By December, actual income for the year is substantially known. Revise the full-year projection and pay the adjusted third installment to minimize year-end interest exposure.

Before ITR filing

Self-Assessment Tax if Balance Remains

Any tax remaining unpaid after March 15 becomes Self-Assessment Tax — payable before filing the ITR. Interest under 234B applies on shortfall from March 16 until actual payment.

FAQ

Frequently Asked Questions

For non-presumptive taxpayers: 15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15. Presumptive taxpayers pay 100% by March 15 in a single installment.

Section 234C charges interest at 1% per month for each quarter where the advance tax payment is below the required cumulative percentage. Section 234B charges 1% per month on the total shortfall from April 1 of the assessment year until actual payment.

Updated Return under Section 139(8A) allows taxpayers to file a revised return (with additional income) within 2 years of the end of the relevant assessment year. It attracts an additional 25% surcharge (within 1 year) or 50% surcharge (within 2 years) on the additional tax payable — but avoids much larger penalties and prosecution.

Senior citizens aged 60 or above who have no income from business or profession are exempt from paying advance tax. They pay tax only as Self-Assessment Tax before filing the return. Senior citizens with business income must pay advance tax like any other taxpayer.

Income found during an Income Tax search (raid) is taxed at 60% flat rate plus 25% surcharge — an effective rate of 75% — plus penalties of up to 300% in some cases, and potential prosecution. Voluntary disclosure through ITR-U costs a fraction of this.
