Last day to file: Here is how to file advance taxes Image by mohamed Hassan from Pixabay Today (March 15) is the last day to file advance taxes. These are for salaried, freelancers and businesses. However, it is for people whose total tax liability is Rs 10,000 or more in a financial year. But a senior citizen, not having income from business or profession is not liable to pay advance tax. As per the law, specified assessees have to estimate their income, compute income-tax liability and pay taxes in four instalments during the course of the financial year. The assessees are usually not expected to pay taxes in one instalment.
