The issue hinges on the tax on toll calls. Under the law establishing the tax, toll calls had to be defined, and were defined as a distance based charge -- what informally was called Long Distance. As long a distance was one component in the charge, minutes could also be used.
But in recent years distance has stopped being a factor and minutes became the factor in toll charges. Since the law stated toll calls were distance based, and that's just not the case any longer, first one federal circuit court, than another, and most recently the fifth federal circuit in a row ruled against the IRS. So the IRS finally caved in, and will allow all taxpayers who paid the 3% excise tax on toll calls to apply for a refund of this tax. The period is from the first court ruling in March 2003, until the final demise of this tax, June 30, 2006.
The IRS will be announcing how to claim the credit, which will be either the actual amount you paid if you have the bills, or a simplified method if not. That will be announced before next tax season.
For the past 10 years I have been a professional tax preparer, and am "so looking forward" to this new credit :-(
