Falsifying Business Expenses
Small business owners make many small purchases for their businesses. If a small business owner purchases a hammer, a television set, and a printer, who is to say whether those purchases were made for the business or for the business owners personal (non-business) use? Generally speaking, if the product purchased could have a business use, this is difficult for the IRS to detect.
