"President Joe Biden is proposing to double the size of the IRS, by hiring nearly 87,000 new workers over the next decade, ...."
if the fucking Republicans would stop cheating on their taxes, we wouldn't need any IRS agents.
The IRS is way understaffed. Every so often there might be some fuckup, last year all of California got an automatic extension due to the floods, so we didn't have to file an extension. But they erroneously failed to apply that to 401k plans. We got a computer generated letter of a $15k penalty on my wife's limited partnership's 401k plan (which has one participant, her). It took 2 months to get an appointment for a 5 minute call to fix it.
If they weren't understaffed, the fuckup probably doesn't happen, and if did, we could have fixed it the day we got the letter. Multiply the amount of time random citizens spend on hold with the IRS and the economic cost of that, additional IRS agents at current staffing levels would be a big cost savings.
