The income tax return filing doesn't sound sweet, especially when the time to file the income tax return has approached. Thankfully, the Income Tax Department has given us the e-filing facility for all categories of Income Tax Returns (ITRs). Payment of tax is just not enough as we need to file our returns as well. And, this return is filed by every individual, companies, entities who readily pay their taxes on time every financial year. It is a must to file ITR and, hence, you should avoid filing it late as you may end up paying penalty charges under section 234F of the Income-Tax Act, 1961. A penalty of Rs 5000 will be applicable for a return filed after 31st July but before 31st December of the relevant assessment year. In case of ITR is filed after 31st December, a penalty of Rs 10,000 will be levied.
