WASHINGTON – The Internal Revenue Service announced that interest rates will remain the same for the calendar quarter beginning Oct. 1, 2012.
The rates will be:
• three (3) percent for overpayments [two (2) percent in the case of a corporation];
• three (3) percent for underpayments;
• five (5) percent for large corporate underpayments; and
• one-half (0.5) percent for the portion of a corporate overpayment exceeding $10,000.
Under the Internal Revenue Code, the rate of interest is determined on a quarterly basis. For taxpayers other than corporations, the overpayment and underpayment rate is the federal short-term rate plus 3 percentage points.
