I only reported half my income on my tax forms
You're kidding, why didn't you report all your income on your taxes?
The income I don't want to report, Fuck the taxes
Well, the truth will come to light at some point and it can get you into trouble. I do not think that it is okay to lie on your taxes.
I don't care, this government needs more money, I love to evade the IRS. It's not like the government is going to miss that money anyway.
If you get caught lying on your taxes, you're going to get audited and your wages will be garnished... or worse, you could go to prison. It's not worth it to lie on your tax return.
