Business Taxes(p5)

rule
The form of business you operate determines what taxes you must pay and how you pay them. The following are the four general kinds of business taxes.
See Table 2 for the forms you file to report these taxes.
Deposit
You may want to get Publication 509. It has tax calendars that tell you when to file returns and make tax payments.

Income Tax(p6)

rule
All businesses except partnerships must file an annual income tax return. Partnerships file an information return. Which form you use depends on how your business is organized. See Table 2 to find out which return you have to file.
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.

Self-Employment Tax(p7)

rule
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.
You must pay SE tax and file Schedule SE (Form 1040) if either of the following applies.
  1. Your net earnings from self-employment were $400 or more.
  2. You had church employee income of $108.28 or more.
Use Schedule SE (Form 1040) to figure your SE tax. For more information, see Publication 334, Tax Guide for Small Business.
Deposit
You can deduct a portion of your SE tax as an adjustment to income on your Form 1040.

The Social Security Administration (SSA) time limit for posting self-employment income.(p7)

rule
Generally, the SSA will give you credit only for self-employment income reported on a tax return filed within 3 years, 3 months, and 15 days after the tax year you earned the income. If you file your tax return or report a change in your self-employment income after this time limit, the SSA may change its records, but only to remove or reduce the amount. The SSA will not change its records to increase your self-employment income.

Employment Taxes(p7)

rule
This section briefly discusses the employment taxes you must pay, the forms you must file to report them, and other forms that must be filed when you have employees.
Employment taxes include the following.
If you have employees, you will need to get Publication 15, Circular E, Employer's Tax Guide. If you have agricultural employees, get Publication 51, Circular A, Agricultural Employer's Tax Guide. These publications explain your tax responsibilities as an employer.
If you are not sure whether the people working for you are your employees, see Publication 15-A, Employer's Supplemental Tax Guide. That publication has information to help you determine whether an individual is an employee or an independent contractor. If you classify an employee as an independent contractor, you can be held liable for employment taxes for that worker plus a penalty. An independent contractor is someone who is self-employed. Generally, you do not have to withhold or pay any taxes on payments to an independent contractor.

Federal Income, Social Security, and Medicare Taxes(p7)

rule
You generally must withhold federal income tax from your employee's wages. To figure how much federal income tax to withhold from each wage payment, use the employee's Form W-4 (discussed later under Hiring Employees) and the methods described in Publication 15.
Social security and Medicare taxes pay for benefits that workers and their families receive under the Federal Insurance Contributions Act (FICA). Social security tax pays for benefits under the old-age, survivors, and disability insurance part of FICA. Medicare tax pays for benefits under the hospital insurance part of FICA. You withhold part of these taxes from your employee's wages and you pay a part yourself. To find out how much social security and Medicare tax to withhold and to pay, see Publication 15.

Federal Unemployment (FUTA) Tax(p7)

rule
The federal unemployment tax is part of the federal and state program under the Federal Unemployment Tax Act (FUTA) that pays unemployment compensation to workers who lose their jobs. You report and pay FUTA tax separately from social security and Medicare taxes and withheld income tax. You pay FUTA tax only from your own funds. Employees do not pay this tax or have it withheld from their pay.
