WASHINGTON ― The Internal Revenue Service today announced that interest
rates will remain the same for the calendar quarter beginning Jan. 1,
2013. 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.
Generally, in the case of a corporation, the underpayment rate is the
federal short-term rate plus 3 percentage points and the overpayment rate is
the federal short-term rate plus 2 percentage points. The rate for large
corporate underpayments is the federal short-term rate plus 5 percentage
points. The rate on the portion of a corporate overpayment of tax exceeding
$10,000 for a taxable period is the federal short-term rate plus one-half (0.5)
of a percentage point.
The interest rates announced today are computed from the federal short-term
rate determined during October 2012 to take effect November 1,
2012, based on daily compounding.
Revenue Ruling 2012-32, announcing the rates of interest, is attached and
will appear in Internal Revenue Bulletin 2012-52, dated December 27, 2012.
