The federal income tax is a pay-as-you-go tax. You must pay the tax 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. If you are not required to make estimated tax payments, you may pay any tax due when you file your return. For additional information refer to Publication 583.
Generally, you must pay taxes on income, including self-employment tax (discussed next), by making regular payments of estimated tax during the year. For additional information, refer toEstimated Taxes.
Self-employment tax (SE tax) is a social security and Medicare tax primarily for individuals who work for themselves. Your payments of SE tax contribute to your coverage under the social security system. Social security coverage provides you with retirement benefits, disability benefits, survivor benefits, and hospital insurance (Medicare) benefits.
Generally, you must pay SE tax and file Schedule SE (Form 1040) if either of the following applies.
If your net earnings from self-employment were $400 or more.
If you work for a church or a qualified church-controlled organization (other than as a minister or member of a religious order) that elected an exemption from social security and Medicare taxes, you are subject to SE tax if you receive $108.28 or more in wages from the church or organization.
