What is the Form 1040-ES?
The Form 1040-ES is a U.S. tax form used by individuals to calculate and pay estimated quarterly taxes on income that is not subject to withholding, such as self-employment income, rental income, or investment income. It includes worksheets to help taxpayers estimate their tax liability for the year and determine how much to pay in each quarter. This form is typically used by freelancers, small business owners, and others who receive income outside of traditional payroll employment.
