My current household gross income is 110k from two jobs (wife and mine).

I interviewed earlier in the week for a position. It is similar to job I do now (designing training material). Pay rate would be close to 110k for this position.

Position has close to 75-100% travel. I must bill 50 hours per week to the client I am supporting. Some of the billing can come from work out of a home office, other billing would be when I am at client site.

When at company site, the travel reimbursement is a little different. Instead of reimbursing for a hotel and a rental car, the company provides a stipend to cover the expense. If I chose to buy a car and buy a condo in the city (3000-4000 miles from where I live now) where my client is, I could do that if the stipend covers it.

I need help with the taxes side of this:

1) Is that stipend taxed as income?
2) I know SS is on first 93k of earned income (per individual) at 3.5% (or something similar). I assume if I made 110k gross, dollars 93001-110000 do not get the 3.5% SS tax?
3) I know there would be tax benefits of working from home (writing off home office and utilities to support this). Is the calculation 25% of all utilities? I don't think so...

House is 3200 sq ft. Room I would convert to an office is about 400 square feet. I assume I would get 25% of the 400/3200=25% of 1/12 of my ulitilies back at end of year?

Utilities- I could write off 1/48 of my
a) heat
b) water
c) trash
d) mortgage payment?
e) anything else?

Thoughts? Am I missing anything.

FYI if I took this job, wife would stop working.
