Why the Different Deadlines?
The core difference lies in how income is earned and taxed. Salaried income is predictable, and tax is deducted at source (TDS) by the employer monthly. Business income, however, fluctuates. To ensure a steady flow of revenue and prevent a massive tax burden
at year-end, the government requires business earners to estimate their income and pay tax on it throughout the year. This system is known as 'advance tax'. If your total tax liability for the year is expected to be ₹10,000 or more, you are required to pay advance tax. This applies to self-employed professionals, business owners, and even salaried people with significant other income.
The Advance Tax Calendar: Key Quarterly Dates
Unlike a single year-end payment, advance tax is paid in quarterly instalments. For the Financial Year 2025-26 (Assessment Year 2026-27), the schedule for most businesses and professionals is as follows: * **By June 15, 2025:** Pay 15% of your estimated annual tax. * **By September 15, 2025:** Pay up to 45% of your estimated tax (including the first instalment). * **By December 15, 2025:** Pay up to 75% of your estimated tax (including previous instalments). * **By March 15, 2026:** Pay 100% of your estimated tax. Missing these deadlines can result in interest penalties under sections 234B and 234C of the Income Tax Act. It's crucial to re-evaluate your income before each deadline to ensure your payments are accurate.
Final ITR Filing: The October & November Deadlines
After the financial year ends on March 31, you must file your final Income Tax Return (ITR), which reconciles your estimated income with your actual earnings. While the deadline for salaried individuals is typically July 31, 2026, the dates are different for businesses. * **October 31, 2026:** This is the due date for businesses and professionals whose accounts require a tax audit. A tax audit is a mandatory review of your financial records by a Chartered Accountant. * **November 30, 2026:** This deadline applies to businesses that are required to furnish a report related to international or specified domestic transactions. For businesses and professionals who do *not* require a tax audit, the due date for filing ITR for FY 2025-26 can vary, with some sources indicating a July 31 and others an August 31, 2026 deadline for ITR-3/ITR-4 filers. It's essential to verify the specific date for your category as the deadlines approach.
What is a Tax Audit and Does It Apply to You?
A tax audit under Section 44AB is mandatory if your business turnover or gross receipts exceed a certain threshold. For FY 2025-26, a tax audit is generally required if: * Your **business turnover** exceeds ₹1 crore. This limit is increased to ₹10 crore if your cash receipts and payments are 5% or less of the total. * Your **professional gross receipts** exceed ₹50 lakh. An audit also becomes mandatory if you are under the presumptive taxation scheme but declare profits lower than the prescribed rate and your total income exceeds the basic exemption limit. Being subject to a tax audit is what pushes your final ITR filing deadline to October 31.
Choosing the Right ITR Form
The type of ITR form you file is also different. While salaried individuals typically use ITR-1 or ITR-2, those with business or professional income must use different forms. * **ITR-3:** This is for individuals and Hindu Undivided Families (HUFs) who have income from a proprietary business or are carrying on a profession. This is the form you use if you maintain regular books of accounts. * **ITR-4 (Sugam):** This form is for those who opt for the Presumptive Taxation Scheme under Sections 44AD, 44ADA, or 44AE, which allows for simplified income calculation as a percentage of turnover. Filing the wrong form can result in your return being marked as defective by the tax department.
