Form IT-20NP is the official tax return document used by the Indiana Department of Revenue for nonprofit organizations that generate Unrelated Business Income (UBI). Even though an organization may hold tax-exempt status, it is still required to file this form if it earns income from trade or business activities that are not substantially related to its exempt purpose, mirroring the requirements for the federal Form 990-T. This document allows the organization to calculate its Adjusted Gross Income Tax on those specific non-exempt earnings, apply for specific state deductions and credits, and report any Sales or Use Tax due to the state. Effectively, it reconciles the federal taxable unrelated business income with Indiana’s specific tax laws to determine if the nonprofit owes the state money or is entitled to a refund.

You should send the completed Form IT-20NP, along with any required schedules and payment, to the Indiana Department of Revenue, PO Box 7228, Indianapolis, IN 46207-7228.
