what form does small business use for taxes
Use Form 1040-ES â You can calculate your quarterly estimated tax payment using Form 1040-ES (the same form used to pay estimated taxes), which includes a worksheet that helps you estimate how much you owe for the current year. Corporations should use Form 1120-W to calculate estimated taxes. Refer to Last Yearâs Return â If you have been in business for a while, you can refer to your previous year's federal tax return.
