IRS Interest Rates Remain the Same for the First Quarter of 2018

The IRS recently announced that interest rates will remain the same for the calendar quarter beginning Jan. 1, 2018. The rates will be:
​

• four (4) percent for overpayments [three (3) percent in the case of a corporation]
• 1 and one-half (1.5) percent for the portion of a corporate overpayment exceeding $10,000
• four (4) percent for underpayments
• six (6) percent for large corporate underpayments

​
Under the Internal Revenue Code, the interest rates are determined on a quarterly basis. For individual taxpayers, the overpayment and underpayment rate is the federal short-term rate plus 3 percentage points.
