1 For example, if you had $800.00 profit from self-employment, you would multiply 800 by .9235. 2  800 x .9235 = 738.80. 3  You would enter 738.80 on line 4 of the Short Schedule SE form. 4  If this amount is less than $400 you do not need to pay self-employment tax.
it is matter composed of organic compounds that has come from the remains of organisms such as plants and animals and their waste products in the environment organic molecules can also be made by chemical reactions that don t involve life
Don't forget that organic matter is generated primarily with energy from sunlight. Plants are just biological solar collectors and oil just stored energy from hundreds of millions of years of biological activity. Clearly it's more efficient to skip the hundreds of millions of years part and go directly to biofuels.
