The Shrifins have already been accused of tax evasion so how hard is to leap that they would do it again where scrutiny is harder. Here's a potental racket:
Rent your house.
Have it cleaned...potentially by a business you have a side interest in.
Pass along the full exaggerated cost of cleaning to the renter.
Then claim the entire cleaning expense for tax purposes.
Does that sound like something someone charged with fraud and tax evasion might try to pull. It's an idea. Let's let the IRS check it out. I'm sure the Shifrins are well on their radar.
