If you get an envelope from a company called the "Internal Revenue Service,"

This group operates a scam around this time every year. Their letter claims that you owe them money, which they will take and use to pay for the operation of essential functions of the United States government. This is untrue! The money the IRS collects is used to fund various inefficient and pointless social engineering projects.
This organization has ties to another shady outfit called the "Social Security Administration," who claim to take money from your regular paychecks and save it for your retirement. In truth, the SSA uses the money to pay for the same misguided make-work projects the IRS helps mastermind.
These scam artists have bilked honest, hard working Americans out of billions of dollars. Don't be among them!
Forward this to everyone you know so they too can be informed.
