How do you determine how much money to withhold when self employed?

Answer 1

Self-employment income. A person with income from Self-Employment files Refer to Tax Publication 334, Tax Guide for Small Business, for information. When there is no federal withholding taken out of your self-employment income, you may need to make quarterly estimated tax payments. This is done using a Form 1040-ES (PDF), Estimated Tax for Individuals. How Do I Pay Income Tax? Federal income tax is a pay-as-you-go tax. You must pay it as you earn or receive income during the year. An employee usually has income tax withheld from his or her pay. If you do not pay your tax through withholding, or do not pay enough tax that way, you might have to pay estimated tax. You generally have to make estimated tax payments if you expect to owe taxes, including self-employment tax (discussed later), of $1,000 or more when you file your return. Use Form 1040-ES to figure and pay the tax. If you do not have to make estimated tax payments, you can pay any tax due when you file your return. For more information on estimated tax, see Publication 505, Tax Withholding and Estimated Tax. http://www.irs.gov/publications/p334/ch01.html#d0e1246
