I'm Anne I've been preparing taxes for 27 years and I'll be happy to help you.
The question of whether or not you may write off the whole $2000 depends on a couple of things.
First, I'm assuming that you and your sisters have set up this business as a Partnership (Form 1065). If this is true, then if you don't work for the Partnership (meaning you were JUST an investor), AND the Partnership itself lost money this year, then you MAY qualify to take the full $2000.
I say MAY because again, I don't know if you are actually working in this business or if you are just an investor....also I don't know if only 1 of your sisters is working for the business, and the other sister is also just an investor.
You should receive a K1 from whoever prepares the Partnership tax return that you will include in your personal tax return.
