The Core Misconception About TDS
For many, Tax Deducted at Source (TDS) is the beginning and end of their tax-paying journey. Your employer calculates your tax on salary, deducts it monthly, and that’s that. This works perfectly if your only source of income is your salary. However,
the moment you earn money from other sources, this simple picture gets complicated. Your employer’s TDS calculation only covers the income they pay you. It does not account for capital gains from stocks, rent from a property you own, interest from fixed deposits, or income from a weekend freelance project. This is where advance tax comes into the picture.
What Is Advance Tax and Who Owes It?
Advance tax is based on a simple 'pay as you earn' principle. The Income Tax Act mandates that if your total tax liability for a financial year is estimated to be ₹10,000 or more, you must pay tax in instalments throughout the year, rather than as a lump sum at the end. This rule applies to all taxpayers, including salaried individuals. The key is the ₹10,000 threshold after accounting for any TDS already deducted. If the tax on your non-salary income exceeds this amount, you are legally required to pay advance tax.
Common Scenarios for Salaried Individuals
Several common situations can trigger advance tax liability for someone on a fixed salary. These include: Capital Gains: If you sold stocks, mutual funds, or property and made a profit, the tax on these gains is not covered by your employer's TDS. Interest Income: Banks deduct TDS on interest from fixed deposits, but often only at a rate of 10%. If you fall into a higher tax bracket (20% or 30%), the deducted amount is insufficient, creating a tax shortfall that you must cover. Rental Income: If you own a property and receive rent, this is additional income that you need to pay tax on. Freelance or Consulting Gigs: Income from side projects is a classic example. Even if the client deducts TDS, it's typically at 10%, which may not cover your full tax liability depending on your income slab.
How to Calculate Your Liability
Calculating your advance tax liability is a straightforward estimation process. First, project your total income from all sources for the financial year (FY 2025-26 for payments made in 2026). Include salary, interest, expected capital gains, rent, and any other earnings. Next, subtract any applicable deductions you plan to claim (like those under Section 80C or 80D). Apply the relevant income tax slab rates to this net taxable income to find your total estimated tax for the year. Finally, subtract the total TDS that will be deducted by your employer and on your other incomes. If the remaining amount is over ₹10,000, that's your advance tax liability.
The Payment Schedule for 2026
Advance tax for the financial year 2026-27 is payable in four instalments. These are cumulative, meaning you need to ensure your total paid amount reaches the specified percentage by each date. The due dates are: By June 15, 2026: 15% of the total liability. By September 15, 2026: 45% of the total liability. By December 15, 2026: 75% of the total liability. By March 15, 2027: 100% of the total liability. It's important to note that professionals and businesses opting for the presumptive taxation scheme have a simplified process and need to pay 100% of their tax by March 15 in a single instalment.
The Cost of Ignoring Advance Tax
Failing to pay advance tax, or underpaying it, isn't a matter of a simple fine. The Income Tax Act levies interest for non-compliance. Interest under Section 234C is charged for delaying instalment payments, at a rate of 1% per month on the shortfall for three months. If the total advance tax paid by March 31 is less than 90% of your assessed tax, an additional interest under Section 234B is levied at 1% per month on the shortfall from April 1 until you pay the full tax. These interest charges can add up, making it a costly oversight.
Are There Any Exemptions?
There is a significant exemption available. Resident senior citizens (aged 60 and above) who do not have any income from a business or profession are not required to pay advance tax. They can pay their full tax liability at the time of filing their return without incurring any interest penalty for non-payment of advance tax. For everyone else, including salaried employees with side income, the rules apply.
