ITR Deadline Today: What Is Advance Tax
Simply put, anyone who has an income, where tax is not deducted at the source, is liable to pay advance tax.
It has to be paid if the tax on the income earned exceeds Rs 10,000, after deducting the tax that was already paid at source. Advance tax is the amount of income tax that should be paid in four quarterly instalments for any external income that is not taxed at the source.
It’s a 'pay-as-you-earn' system that breaks up the tax flow evenly throughout the year, into four quarterly payments.
ITR Last Date: Multiple Income Sources
The income from multiple sources, such as investments, capital gains, rental properties and multiple employers, should be declared properly in the ITR filing to avoid notices and penalties.
For taxpayers with multiple sources of income, it’s advisable to declare all income sources and amounts clearly in the ITR form. It’s also necessary to submit relevant documents where needed.

However, if the total income is below Rs 5 lakh, the penalty is limited to Rs 1,000. It’s advisable to file your ITR within the due date and avoid the penalties.
