Build Recurring Income

I am about to start a new business entity (probably an LLC), but I have already been earning income (intended for this business) under my name and personal bank account, since the LLC has not been formed yet and I do not have a business bank acount yet.

I will probably be filing IRS Form 8832 so that the LLC is taxed like a corporation, and can seperate my personal income tax from my business income tax.

Can I transfer income related to the business that i personally received before starting the LLC into the LLC so that the business would be taxed on it, and it would not be applicable towards my personal tax? How would this be done?

The income was received within the 2006 tax year, so I'm assuming i may need to start the LLC within 2006 as well?

Last year I worked for a startup as an independent contractor. I was paid in cash and also given equity shares. The company sold a few weeks ago and I received cash from the buyer in exchange for my shares. I know I'm going to have to pay taxes on it but I wonder if it is investment income or wage income? I read the IRS publication on income (#525) but that seemed to focus on 'stock options' which i believe is something different. I would love some help and advise from your experience.
Thanks,

Yoink!

Under what conditions would rental income be considered an active trade or business income for determining the business income limitation for section 179 expense? I cannot seem to find any concrete evidence either way on this.

My friend is a professional snowboarder who set up an S Corp last year at his accountant's insistence. He has parted ways with the accountant and wants to file on his own, but on the "Income tax summary" he received from his accountant last year, there is "Business income" and "Rent, royalty, partnership, SCorp, Trust" income and he has amounts in both areas. My question is how the accounant determined which amounts belonged in which areas–his income comes directly from his sponsors and he gets 1099 forms from them, and the only other income he has is from contest wins. He is the only owner/employee of the SCorp and does not have any complex accounting issues. I pretty much just want to know if income needs to be separated (onto Schedules C and E) and how this is done.
Thanks!
