Any person having a tax liability of more than ₹10,000 in a financial year after deduction of TDS, has to pay advance tax. Advance tax must be paid by all taxpayers; salaried, freelancers, and businesses. Businessmen and professionals who have opted for the Presumptive Taxation Scheme have to pay the whole amount of their advance tax in one instalment on or before 15th March, or pay all of their tax dues by 31st March. Advance tax is not mandated for senior citizens of or above 60 years of age, who do not carry out business.
