AP can perform the entire authorization function or selected portions of the process in cooperation with your host system. And, because the Visa DPS authorization system is flexible, you may customize support to meet your specific business requirements.
If desired, you can request voluntary Federal tax withholding from your monthly Social Security benefits. You may find doing this easier than paying quarterly estimated tax payments. See http://www.socialsecurity.gov/planners/taxwithold.htm.
The payroll taxes withheld from your wages are not deductible, either from federal or any state income tax. For the year 2012, the Social Security payroll tax rate stood at 4.2 percent for employees, and 6.2 percent for employers. If you are self-employed, you pay both employee and employer shares through self-employment taxes, which you calculate using Form 1040, Schedule SE. The money funds the Social Security trust account, which is used to pay retirement and disability benefits to qualified applicants.
