Interest Rates Relating to Customs Duties Increased

U.S. Customs and Border Protection has updated its list of the quarterly Internal Revenue Service interest rates used to calculate interest on overdue accounts (underpayments) and refunds (overpayments) of customs duties. For the quarter Jan. 1 through March 31, 2019, the interest rates for overpayments are five percent for corporations and six percent for non-corporations, and the interest rate for underpayments is six percent. These rates reflect a one percentage point increase from the previous quarter.
