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
Now, once again, where does the matter come from that forms the mass of wood, branches and leaves? Trees store carbon, sequestered from the air, as the wood and plant material that makes up their mass. OK, so plants (most) use carbon in as a part of their life processes... Knowing this, how much CO 2 is sequestered by an average tree? Well, it very much depends on type of tree. For our example we'll use a mature pine tree (Pinus radiata). An acre of pine trees (~120 trees) has the potential to sequester roughly 5 tons of CO 2 per year. Let's look at part of your carbon imprint, your home, and make an estimate for the CO 2 it might be
