A through e) If reimbursed by the company under an expense report, NON-taxable.

f) I assume you mean deductible, which it is NOT.

G and h) Hard to say; would have to see the W-2.

I) BOTH.

j) Taxes paid to GA should be credit dollar-for-dollar on your Michigan tax return to avod double taxation.

k) YES, a tax return for BOTH states are required.
