Income Tax

The United States imposes an income tax on the taxable income of individuals, corporations, trusts, decedents' estates and certain bankruptcy estates.
Current income taxes are imposed under various provisions of Subtitle A of the Internal Revenue Code of 1986, as amended.

Income Tax: Form 1040

Form 1040 is the standard form for reporting personal income tax returns.
The Form 1040, Individual Income Tax Return, is the starting form for personal Federal income tax returns. Any individual income taxpayer can use Form 1040. Those with uncomplicated tax situations may be able to use the simplified Form 1040A or the even simpler Form 1040EZ instead of Form 1040.
Income tax returns for calendar year taxpayers are due by April 15 of the next year. Income tax returns for fiscal year taxpayers are due on or before the 15th day of the fourth month following the close of the fiscal year.

Income Tax: Form W-2 - Wage and Tax Statement

Form W-2, Wage and Tax Statement, is used to report wages paid to employees and the taxes withheld from them. The form is also used to report FICA taxes to the Social Security Administration. Relevant amounts on Form W-2 are reported by the Social Security Administration to the Internal Revenue Service.
Employers must complete a Form W-2 for each employee to whom they pay a salary, wage, or other compensation as part of the employment relationship.

Income Tax: Form 1099 - MISC & Independent Contractors

Form 1099 is used to report various types of income other than wages, salaries, and tips. Each payer must complete a 1099 for each covered transaction. Three copies are made: one for the payer, one for the payee, and one for the IRS. The form is used to report income only on a calendar year basis. The forms must be filed with the IRS by the end of February immediately following the year for which the income is paid, but copies must be sent to payees by the end of January.
