Taxes for Fix & Flip or short term capital gains

hi All,

Happy Holidays and New year to all of you.

My name is Jonathan, nice to meet you all, and I am a foreign Real Estate investor in the USA.

As most CPA's in Israel dont have the answer for this I decided to take the chance and ask it here :)

Part of my business is doing Fix & Flips or new constructions in which at the end i sell the properties. Most of these projects take less than a year which means they are considered as Short Term Capital Gain.

I would like to know if anyone here know what are the taxes that needs to be paid for such a deal. i know it says that it is according to my annual ordinary tax but i dont pay any taxes in the US as i dont live there nor I am a citizen.

i hope someone here has the answer :)

thanks
