If they don't take it as personal income, then they could be in trouble if they are ever sued or audited by at state or federal agency.
If you try to deduct it as a business expense you may be in trouble, otherwise you put the girlfriend on payroll.
That’s why you take it as personal income and pay the tax. If you want to put a girlfriend on your payroll have at it. To me it is a bad business decision however since you don’t own a business it doesn’t matter.
Why would you? As long as you don't try to deduct the amount as a business expense the chance of ever getting caught is zero.
Nevada is a right to work State. Putting your girlfriend on payroll means you can fire her without cause.
First you are breaking down the barrier between you and your business, that means that if you were being sued, they could go through the corp, show that you mix your personal and business accounts and just like that your can be sued personally and the corp is no longer the barrier. The same with the IRS, if you are having issues, they can go through the barrier and put leans against your personal property.
Next whether you get caught or not should not be the guide, it should be whether it is ethical or not and it isn't The income is a personal, your business it is an expense, the way it is reported and tax differ. So, there is tax evasion. The business doesn't pay your individual taxes. It isn't ethical. If you have other stockholders then you are stealing from them and the business. Again, ethics are violated. Having a girlfriend on the payroll, right to work state or not, it could end in a sexual harassment case if she sues you for wrongful termination, which she could under federal statutes, not state.
So I and many businesses wouldn't run their businesses as unethical as you may want to. No wonder you have a bad view of business owners, your are gaming the system, I wouldn't deal with other businesses that played those games, what other dealings are you dishonest with. Product? Employees? Quality? Your word?
