1. No, the IRS can't just "take" your money if it "wants to." If you owe taxes, the IRS has a case against you and can force you to pay your taxes.
2. "...Even threaten your home or business." If you have that home or business because you didn't pay your taxes, you stole the money used to maintain that home and business. We'll get to who, exactly, you stole that money from in a moment, but- Spoilers!- I don't feel sorry for you.
3. "One phone call to Optima Tax Relief can stop the IRS targeting you...." nope. It CAN stop the "harassing letters" (I wonder- if you write to someone who owes YOU money, do you consider that "harassment?") It CAN stop the phone calls from the IRS. Know what's really wrong with this statement, though? It's just as accurate if you cut out the "Optima Tax Relief" part. If the IRS is sending you letters (the IRS does not operate over the phone, to discourage scammers) you can stop that by contacting the IRS and expressing an interest in working out your issues which (another Spoiler alert) are NOT WITH THE IRS.
4. Let's just cut to the chase. Nobody owes money to the IRS. If you don't pay your taxes, you owe money to the USA. You are a deadbeat freeloader who doesn't want to contribute to the society that is allowing you to succeed. If you are prospering by not paying your fair share, you OUGHT to be called on your BS and forced to cough up, just like the rest of us. Who the hell do you think you are, Donald Trump?
Don't want to be "harassed" to pay what you owe? Pay what you owe. Don't want your house or business or bank accounts seized? Don't maintain them by cheating and avoiding your responsibilities. And if you lose your Stuff because you got caught, pardon this Taxpayer for not having a single s--t to give for you. I'm busy waiting for my refund, thanks anyway.
