 While an independent watchdog group says services offered by the Internal Revenue Service have improved, there are some areas that still need to be worked on. For example, taxpayer advocates say the IRS is still too slow in resolving cases of identity theft, an area where there has been an increase in the number of cases. On average, the amount of time it takes to resolve such complaints going from 19 to 22 months. Independent taxpayer advocates say those kind of delays are unconscionable.
