Who Needs to Pay Advance Tax?
Advance tax is essentially a 'pay-as-you-earn' system for your total income. If your estimated tax liability for the financial year (April 1, 2026, to March 31, 2027) is ₹10,000 or more after accounting for any Tax Deducted at Source (TDS), you are required
to pay advance tax. This applies to most self-employed professionals like doctors, lawyers, consultants, architects, and freelancers whose income isn't fully covered by TDS. Salaried individuals who have significant additional income from sources like rent, capital gains, or freelance projects also fall under this rule. However, resident senior citizens (aged 60 and above) who do not have any income from a business or profession are exempt from paying advance tax.
Understanding the September 15 Deadline
The Income Tax Act mandates that advance tax be paid in four instalments throughout the year. The upcoming deadline of September 15, 2026, is for the second instalment. By this date, you must ensure that a cumulative total of at least 45% of your total estimated tax for the year has been paid. This 45% includes the 15% you should have already paid by the first deadline on June 15. So, if you paid the first instalment correctly, you need to pay an additional 30% of your total estimated tax liability by September 15. Some relief is available; if your cumulative payment reaches at least 36% by September 15, you may avoid interest penalties for a shortfall in this specific instalment.
The Magic of Presumptive Taxation: Section 44ADA
For many professionals, Section 44ADA offers a major simplification. This presumptive taxation scheme allows you to declare 50% of your total gross professional receipts as your taxable income, without needing to maintain detailed books of accounts or get them audited. The remaining 50% is assumed to cover all your business expenses. This scheme is available to resident professionals like lawyers, doctors, engineers, architects, accountants, interior decorators, and technical consultants, among others. The standard gross receipts limit to use this scheme is ₹50 lakh. This limit is extended to ₹75 lakh if your cash receipts are no more than 5% of your total gross receipts for the year. A key benefit for those under Section 44ADA is that they are exempt from the quarterly instalment schedule and can pay their entire advance tax liability in a single instalment by March 15, 2027.
How to Calculate Your September Payment
First, estimate your total professional receipts and other income for the full financial year (ending March 31, 2027). If you're not using the presumptive scheme, deduct all your expected business expenses to arrive at your estimated profit. Calculate the income tax on this profit as per the applicable slab rates. From this tax amount, subtract any TDS that has been or will be deducted. If the remaining tax payable is over ₹10,000, that is your advance tax liability. For the September 15 deadline, you need to ensure 45% of this total liability is paid. For those using Section 44ADA, simply calculate 50% of your estimated annual gross receipts—this is your taxable income. While you have the option to pay the full tax by March 15, 2027, you can still choose to pay in instalments to manage cash flow.
The Cost of Missing the Deadline
Failing to pay or underpaying your advance tax instalments has financial consequences. The Income Tax Act levies interest penalties for non-compliance. Interest under Section 234C is charged at 1% per month for a period of three months on the shortfall amount for the September instalment. Furthermore, if your total advance tax paid by March 31, 2027, is less than 90% of your final assessed tax, an additional interest under Section 234B at 1% per month will be charged from the beginning of the next financial year until the tax is fully paid. These interest charges are mandatory and cannot be waived, making timely payment crucial.
