As the tax filing deadline of April 15 approaches, many Americans are rushing to meet the requirement, with nearly one-third of people filing just before the deadline. For those who need more time, the IRS offers the option to file for an automatic extension using the IRS Free File system, available to individual filers regardless of income. This extension can be crucial for those who missed the April 17 deadline, as failing to file can lead to penalties. Additionally, the IRS has highlighted that taxpayers have until May 17 to claim refunds from 2020, urging prompt action to avoid losing out on potential refunds. Tips and guides are available for last-minute filers, including how to avoid unexpected fees and file extensions online.
