I'm wanting to add an interest component to a long term loan liability account. The rate is fixed for the duration of the loan.This tax discourages long-term, low-interest loans to directors.. It is currently anticipated that this construction loan will close in January '01. See "PLAN OF FINANCE" herein. I'm talking to you about directors loan accounts what they are charging interest on them what amount of interest you can charge and some common pitfalls.
