Interest rates unchanged for third quarter 2017

Internal Revenue Service interest rates will hold at the same level for the calendar quarter beginning July 1.

The IRS said the rates will be:

  • 4 percent for overpayments (3 percent in the case of a corporation);
  • 1.5 percent for the portion of a corporate overpayment exceeding $10,000;
  • 4 percent for underpayments; and
  • 6 percent for large corporate underpayments.

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 0.5 of a percentage point.

The interest rates are computed from the federal short-term rate determined during April 2017 to take effect May 1, 2017, based on daily compounding.

Revenue Ruling 2017-13, announcing the rates, will appear in Internal Revenue Bulletin 2017-26, dated June 26.
