As the Internal Revenue Service starts requiring companies to disclose more information about uncertain tax positions (UTPs), a survey shows that business executives are anxious about how to describe such positions.

Forty-four percent of the 1,100 senior executives surveyed by KPMG's Tax Governance Institute say their biggest concern is coming up with a description of their uncertain tax positions–those for which they've taken a reserve. Twenty percent say their biggest concern relates to the IRS's ability to administer the program related to uncertain tax positions, and 15% cite the scope of those required to file forms related to uncertain tax positions under the new regulations.

Thirty-nine percent of the executives say their company has started to do the work necessary to comply with the new regulations, while 33% say their company has not started preparations, according to the survey.
