Tax forms are official documents used to report income, expenses, and other financial information to the government. They are essential for individuals and businesses to calculate their tax obligations and ensure compliance with tax laws. Common tax forms include the 1040 for individual income tax and the W-2 for reporting wages. Filing tax forms accurately is crucial to avoid penalties and ensure that taxpayers receive any refunds they may be entitled to. Many people use tax preparation software or hire professionals to help them complete these forms, making the process easier and more efficient.
