According to a report in the Tax Analyst, the IRS will close some taxpayer assistance offices. The Wall Street Journal reported that 70 offices will be closed in order to handle a 1% drop in funding for taxpayer assistance. Unfortunately, that will drive more taxpayers to call the IRS where there is a 50% chance you will get a correct answer to your question.
In the same article in the Tax Analysts, IRS Commissioner Mark Everson notes that he’d like to see any firm that sends tax work overseas be required to notify taxpayers of that fact. It is unclear, though, whether the IRS has the power to make such a disclosure regulation.
