The Internal Revenue Service (IRS) collects revenue for the United States federal government. The IRS was nicknamed “Internal Rectal Service” by Congressman James Traficant (D-Ohio), who used the nickname in 2000 (“It is time to abolish both the income tax and the IRS. Replace it with a national retail sales tax. Mr. Speaker, one last thing. I yield back the lies, crimes, dental needs, and amnesia of the ‘Internal Rectal Service.’”) and 2001 (“From the womb to the tomb, Madam Speaker, the Internal Rectal Service is one big enema.”). The IRS has been nicknamed “Internal Rectum Service” since at least March 2003.
 
The IRS has also been nicknamed the “Infernal Revenue Service” (cited in print since at least 1956), “Income Reduction Service” (cited in print since at least 1990), “Internal Rotten Scoundrels” (cited at an “Abolish the IRS” rally in 2013), “Internal Revenge Service” (popular since April and May 2013), “IRSS” (IRS + SS, popular since May 2013) and “Immoral Robbery Service” (printed on shirts in 2017).

The Internal Revenue Service (IRS) is the revenue service of the United States federal government. The agency is a bureau of the Department of the Treasury, and is under the immediate direction of the Commissioner of Internal Revenue. The IRS is responsible for collecting taxes and the interpretation and enforcement of the Internal Revenue Code.
 
The first income tax was assessed in 1862 to raise funds for the American Civil War, with a rate of 3%. Today the IRS collects over $2.4 trillion each tax year from around 234 million tax returns.

Traficant’s speeches add color to House
Here are some examples from indicted Ohio rep.
Sunday, May 06, 2001
By Peter Carlson and Margaret Smith, The Washington Post
WASHINGTON—Mr. Speaker, if we may?
 
Rep. Jim Traficant, D-Ohio, was indicted Friday on charges of tax evasion, bribery and obstruction of justice. Among its other consequences, this event could potentially silence the House’s unofficial King of the Surrealistic One-Minute Speech.
(...)
Here is a small greatest hits sampling of the wit and wisdom of Jim Traficant:

. On the IRS: “From the womb to the tomb, Madam Speaker, the Internal Rectal Service is one big enema. Think about it: They tax our income, they tax our savings, they tax our sex, they tax our property-sales profits, they even tax our income when we die. Is it any wonder America is taxed off? We happen to be suffering from a disease called Taxes Mortis Americanus. Beam me up!” (March 20, 2001)

New Forum - IRS Fraud - Internal Rectum Service
I started a new forum today, which most of you are aware of through the mass email I sent out to you, but some mihgt have missed it and am sure tat it ended up in some peoples spam box and was never seen. thus I want to formally announce this new forum, and ask for your usual, spirited and hearty participation.

This single forum is long over due, as one of the chief strangleholds, as most of us are aware, is the Feral [sic] Reserve Corporation. And its domestic enforcement agency, the IRS, better known as the Internal Rectum [sic] Service.
