Summary of this article
March 15 is final advance tax deadline.
Applies if tax liability exceeds Rs 10,000.
Missing deadline attracts 1% monthly interest.
March 15, 2026, is an important deadline for the taxpayers as it is the last date by when the final instalment of advance tax for the current financial year has to be paid. Advance tax refers to income tax that individuals and businesses pay in instalments over the course of the financial year.
Under the Income-tax Act, 1961, any taxpayer whose tax liability is more than Rs 10,000 in a financial year has to pay the advance tax; However, this rule applies to individuals, freelancers, professionals, and businesses whose taxes are not fully covered through deduction of tax at source (TDS). Salaried workers usually don't have to worry about paying advance tax since their employers deduct tax in the form of TDS from their income. However, advance tax may be applied if they have other streams of income. These incomes can be capital gains from assets, such as stocks, mutual funds or property, or earnings from freelancing or side businesses.
People who have other sources of income, like freelancers and self-employed professionals, usually need to calculate their yearly income and pay taxes on it. However, tax exemption is provided to senior citizens aged 60 years and above who do not earn from a business or profession.
Tax Payment Schedule
Advance tax is a relief to those who don’t want to pay their taxes in one big chunk, but want to ease tax payment into lump sums. The tax must be filed in four instalments based on limits set by the government. The deadlines are as follows;
June 15, 2025: At least 15 per cent of the total tax liability
September 15, 2025: At least 45 per cent of the total tax liability
December 15, 2025: At least 75 per cent of the total tax liability
March 15, 2026: 100 per cent of the estimated tax liability must be paid
By March 15, 2026, taxpayers should have cleared the entire advance tax amount for the financial year (FY 26). There is an exception for small businesses who opt for this option of paying taxes. They are allowed to pay their advance taxes in a single payment by March 15, 2026, instead of multiple instalments.
If someone fails to pay this required advance tax or pays less than the required amount by the due date, the Income Tax Department may charge the liable penalty interest. The rate of interest for this is set at 1 per cent per month of the unpaid or leftover amount until the next tax due date is paid.
If the last due date is also missed, taxpayers have a chance to clear their dues before the end of the financial year. The outstanding advance tax can be paid until March 31, 2026. However, doing this will only attract more interest for the month under Section 234C of the Income-tax Act, 1961.
For taxpayers, paying this tax on time helps them avoid the unnecessary interest charges. One must also properly calculate their income and make the timely payments to avoid the last minute stress and additional financial penalties.
