(b) A credit taken by a taxpayer on the taxpayer's return does not accrue interest. (c) For a refund claimed before September 1, 2005, and granted for a report period due on or after January 1, 2000, the rate of interest is the rate set in Section 111.060 . (c-1) A refund, without regard to the date claimed, for a report period due before January 1, 2000, does not accrue interest.
