The Streptococcus bovis/Streptococcus equinus complex includes four major species that all belong to group D streptococci (GDS); this taxonomy was established in 2003 and is summarized in the Table (table 1) [1].
For 2014, the self-employment tax rate is 15.3 percent. The rate is divided into two parts: 12.4 percent for social security and 2.9 percent for Medicare. But as a self-employed individual, you are considered both the employer and the employee, which makes the entire self-employment tax burden yours.
The return must include a Schedule SE, which you use to calculate how much self-employment tax you owe. However, when you are filling out your 1040, the IRS allows you to deduct a portion of the self-employment tax payments you make as an adjustment to income. You can deduct between 50 and approximately 57 percent of your self-employment tax payments. The precise amount depends on how much self-employment income you earn.
