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 law requires employers to withhold taxes from employee earnings to fund the Social Security and Medicare programs. These are called Federal Insurance Contributions Act (FICA) taxes. Your employer also pays a tax equal to the amount withheld from employee earnings. The self-employed pay Self-Employed Contributions Act (SECA) taxes on net earnings. SECA taxes also fund Social Security and Medicare. The self-employed pay both the employee and the employer share of SECA. But the law permits them to deduct half of the self-employment tax as a business expense.
