The Internal Revenue Service (IRS) today announced the launch of a new Excel-based calculator designed to assist businesses with large, multi-year construction or manufacturing projects in computing look-back interest. This tool aims to simplify the complex calculations required for Form 8697, Interest Computation Under the Look-Back Method for Completed Long-Term Contracts.
IRS Chief Executive Officer Frank J. Bisignano said, "The IRS is focused on improving and enhancing how we serve taxpayers. We are transforming the IRS into a digital-first agency that provides the best possible experience for taxpayers, and tools like this calculator are an important step in that effort." The calculator is particularly useful for tax professionals, including certified public accountants and enrolled agents.
Look-back interest involves a three-step process: hypothetically reallocating income, computing hypothetical overpayment or underpayment, and calculating interest. The new calculator specifically aids in the final interest computation step, offering a structured framework.
However, the IRS cautions that using the calculator does not guarantee compliance with the law and does not replace authoritative guidance. Taxpayers and practitioners must carefully review the output, consider specific circumstances, and ensure calculations align with I.R.C. Section 460 and Treasury Regulations Section 1.460-6. Feedback on the calculator can be submitted via email.
