Taxes, expenses, W-2 Income and 1099 Income Question

[Jack Black]

Hi ya'll,

I'm full time military and a Realtor.  I made around $1,600 in 1099 income as a Realtor and had about $4,000 in expenses starting up my business.  Can I add up all my income (W-2 from the military and the 1099 income) and deduct the $4k in expenses from my total income?
