IR-2009-54, May 28, 2009
WASHINGTON — The Internal Revenue Service today announced that interest rates for the calendar quarter beginning July 1, 2009, will remain the same. The rates will be:
four (4) percent for overpayments [three (3) percent in the case of a corporation];
four (4) percent for underpayments;
six (6) percent for large corporate underpayments; and
one and one-half (1.5) 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 during April 2009 to take effect May 1, 2009, based on daily compounding.
Revenue Ruling 2009-17, announcing the rates of interest, is attached and will appear in Internal Revenue Bulletin No. 2009-26, dated June 29, 2009.
