The United States Internal Revenue Service uses forms for taxpayers and tax-exempt organizations to report financial information, such as to report income, calculate taxes to be paid to the federal government, and disclose other information as required by the Internal Revenue Code (IRC). There are over 800 various forms and schedules. Other tax forms in the United States are filed with state and local governments. Form 1040 As of the 2018 tax year, Form 1040, U.S. Individual Income Tax Return, is the only form used for personal (individual) federal income tax returns filed with the IRS. In prior years, it had been one of three forms (1040 [the "Long Form"], 1040A [the "Short Form"] and 1040EZ - see below for explanations of each) used for such returns. The first Form 1040 was published for use for the tax years 1913, 1914, and 1915. For 1916, Form 1040 was converted to an annual form (i.e., updated each year with the new tax year printed on the form). Initially, the IRS mailed tax booklets (Form 1040, instructions, and most common attachments) to all households. As alternative delivery methods (CPA/Attorneys, internet forms) increased in popularity, the IRS sent fewer packets via mail. In 2009 this practice was discontinued. Income tax returns for individual calendar year taxpayers are due by April 15 of the next year, except when April 15 falls on a Saturday, Sunday, or a legal holiday. In those circumstances, the returns are due on the next business day. An automatic extension until Oct. 15 to file Form 1040 can be obtained by filing Form 4868. Form 1040 is two abbreviated pages, not including attachments. Prior to the 2018 tax year, it had been two full pages, again not counting attachments, but following the passage of the Tax Cuts and Jobs Act of 2017, the IRS dramatically shortened both pages. The current first page collects information about the taxpayer(s) and any dependents and includes the signature line.
