O.J. Simpson isn't just bad at robbing people ... he's also terrible at paying his taxes ... this according to the IRS.

TMZ obtained a tax lien filed by Uncle Sam, which shows O.J. failed to pay nearly $180k in federal taxes from 2007 through 2010 ... while he was rotting away in a Nevada prison cell.

Here's the yearly breakdown:

2007 - $15,927.89
2008 - $105,119.71
2009 - $49,490.27
2010 - $8,897.20

All totaled up, Simpson allegedly owes $179,435.07.

The lien is just the latest in a string of problems for the former football star -- 7 months ago his FL home was foreclosed on ... and he's still locked up for kidnapping, armed robbery and other charges from a 2007 Las Vegas incident.

Plus, he still OWES MILLIONS to the families of Nicole Brown Simpson and Ronald Goldman ... because, ya know, he killed them.
