Tax season is the time of year when individuals and businesses prepare and file their income tax returns. In the United States, this period typically runs from January 1 to April 15. During this time, taxpayers gather financial documents, such as W-2 forms and receipts, to report their earnings and claim deductions. Filing taxes is important because it determines how much tax a person owes or if they will receive a refund. Many people choose to use tax preparation software or hire professionals, like tax preparers, to help them navigate the process and ensure accuracy in their filings.
