IRS interest rates increase for the third quarter of 2022

WASHINGTON — The Internal Revenue Service today announced that interest rates will increase for the calendar quarter beginning July 1, 2022. The rates will be:

  • 5% for overpayments (4% in the case of a corporation).
  • 2.5% for the portion of a corporate overpayment exceeding $10,000.
  • 5% for underpayments.
  • 7% for large corporate underpayments. 

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 three percentage points.

Generally, in the case of a corporation, the underpayment rate is the federal short-term rate plus three percentage points, and the overpayment rate is the federal short-term rate plus two percentage points. The rate for large corporate underpayments is the federal short-term rate plus five 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 April 2022 to take effect May 1, 2022, based on daily compounding.

Revenue Ruling 2022-11 announcing the rates of interest is attached and will appear in Internal Revenue Bulletin 2022-23, dated June 6, 2022.
