Deductions & credits

Paula, OK, I just want to do it right & it sounds from reading all the examples, etc. that it might be subjective. I would like to just say 50% & keep it simple. On the other hand, I don't want to cheat myself either now that I need all the help I can get & after not even taking it all those years when I worked out of my office (because the company required it) or even the past few when I just did not take it for simplicity. On one hand I want to just say 50% in the office & 50% in the field. However, after reading some of the examples, well that one make it like it would be 100% because all of my income is generated from the office, even though part of it is completed in the field. Maybe that is like a big company might keep a big office for its employees, even though dependent on the type of business many would spend a great amount of time in the field. It just starts getting more complicated than it seems it should be. Maybe I am the one making it complicated, I don't know. Do you think maybe 60% or 75% might be more accurate? I just want it to be right, but I don't know how to per se' document something like that. I do know that, at least the way I am set up (sort of old fashioned) that if I was not in the office to set things up initially & complete things at the end, there would be no field work. I am just not sure what to say. Thanks again for your input.
