When the IRS audits a return and disallows a deduction or a negative income item (loss), do they give the taxpayer the opportunity to make other changes to the return to remove optional income items that the taxpayer may only have included to offset the deduction/loss?
For example, say on his 2012 return the taxpayer reports a very large deduction or loss of $50,000, which would be way more than his total reported income for the year. So as not to lose the full benefit of the deduction, the taxpayer decides to change the way he has been reporting interest on his savings bonds, which he has been holding for 20 years, to report all the interest that has accumulated to date, rather than waiting until he cashes in the bonds. By reporting the accumulated interest at the same time he takes the large deduction, assume the two items balance each other out and his tax bill for the year is roughly what it would have been in the absence of both items. Of course having changed his methodology for reporting the savings bond interest, he now has to start reporting that interest every year, so he reports it as required on his 2013 return.
So now let's say in 2014 the IRS audits the 2012 return and decides to disallow the 50K deduction or loss. Now all of a sudden he has a gigantic tax bill from reporting the accumulated savings bond interest. Can he now go back and amend the 2012 and 2013 returns to cancel out the change he made to the way he was reporting the savings bond interest? Since it takes a while for an amended return to get processed, will the IRS work with him on this so that he can avoid paying the large tax bill he now owes until the amended return is processed?
