Actually, about 20+ years ago, the IRS had to crack-down on government employees who where not paying all their taxes. Government employees are for the most part exempt from having their pay garnished by anyone including the IRS. It became fashionable to just not pay any taxes owed and the IRS was powerless to collect the money.
As a retired military man, I receive a monthly retirement pension from the Army. The first time I found out about this IRS problem was when I did my tax returns and owned them some money. I sent them they tax return but not the check for the amount I owed.
About a month later I got a letter from the IRS stating what I owed including pentalties and interest, which I expected. The letter indicated that because I was a government employee (actually a retired goverment employee) I had to send them full payment for the taxes I owed, or I had to make arrangements with my employer to deduct payments from my pay so that the amount would be paid in full by January 1st of the next year. If I failed to do either of the above, they would begin to seize assets. Gee, I only owed them about $900 !!
Anyway, I sent them a check and paid off what I owed, but I was annoyed at their strongarmed tactics and looked into why my being retired military had anything to do with why I was treated like a tax dodger?
It turns out that most of the unpaid taxes that the IRS was unable to collect was due from people who were government employees or retired government employee...not just military.
Unable to ganish wages of government employees or their retirement pensions, the IRS could not force them to pay taxes unless they threatened them with seizing of their assets.
At the time the IRS had a very poor success rate for ever collecting back taxes. They lost nearly 9 out of every 10 cases they took to court, often due to poor wording of the tax laws the left them open to interpretation. And the real tax dodgers were able to find so many loop-holes to conceal their assets that the IRS only collected about 10 cents for every dollar of taxes owed.
Of course this was back in the day when the IRS was infamous for seizing childrens bank accounts because their parents owed back taxes. I think George H W Bush changed that by stating that he wanted a "Kinder and Gentler" IRS.
Now the IRS is much more willing to settle for less money immediately since they can spend a lot of money fighting court cases, and still not get the money owed
