Deductions to write off everything?

Remember, Uncle Joe is watching.  He just hired 87000 new agents with unlimited budgets to smack you and your creative deductions down.  He needs all the money he can get to pay for all his giveaways, so I wouldn't try it.

is code for cheating on your taxes which AFAIK is against the law

he can give you a list of guys staying at his place for 10 to 20 who tried it. They can probably tell you where they went wrong. 

If you even think you are going to try and roll a major purchase into an LLC, you may want to know your tax person and trust they really know the law.  Nothing wrong with using legal write offs as long as you're not trying to circumvent the law.  Even if it's legal, doesnt mean the IRS employee who might happen to be screening your flagged entry may not understand the law and still try and assess penalties.  Speaking from experience on a retirement transfer that took a few years to clear up.  Note: If the IRS deems you owe and you decide to fight it, you may want ot be ready to pay it off and note as being under dispute.  Their interest rate is outragous and you could wind up being charged double in just a few years.  And no, they do not give any rate of return if/when the decision becomes in your favor. But go ahead and ask some helo forum and place all your money on the table for that bet.

and taxes.  Same thing.  Treat them with equal respect.
