Form 3468 Investment Credit
Introduction
Form 3468, Investment Credit, allows businesses and tax-exempt organizations to claim credits for certain qualifying investments, including those in renewable energy, rehabilitation, and historic preservation projects. This form allows you to claim investment credits that may reduce your UBIT liability.
For tax-exempt organizations filing 990-T, investment tax credits are first calculated using Form 3468, reported through Form 3800, and can ultimately be used to offset unrelated business income tax (UBIT). When filed alongside Form 990-T, this form supports organizations and businesses in maximizing their tax benefits while encouraging investments in socially and economically beneficial projects.
In this resource guide, we'll delve into the filing purpose of Form 3468, identify the entities required to file, who must file, and address common questions.
What’s New in Form 3468
The latest updates to Form 3468 mainly introduce new compliance steps and some changes to how certain credits work. A key update is the addition of Form 7220, which is now required if you’re claiming a higher credit amount under Sections 48, 48C, or 48E by meeting prevailing wage and apprenticeship (PWA) rules. You’ll need to file this form separately for each project.
There are also small updates to Part I, including new fields like a DOE control number. On the credit side, the advanced manufacturing credit (Part IV) now allows up to 35% for certain investments, while the clean electricity (Part V) and energy credit (Part VI) have added restrictions, especially related to foreign entities and some energy properties. In addition, the transition rule for the rehabilitation credit (Part VII) has been removed.

What is Form 3468?
Form 3468 is used to claim a credit for each investment property and any unused investment credit amount from cooperatives. The purpose of the form is to help taxpayers offset the cost of qualified investments through tax credits, thereby reducing their overall tax liability.
These credits can be claimed for various investments, such as energy property, new equipment, and qualified rehabilitation expenditures. They not only reduce tax liability but also encourage businesses and organizations to invest in sustainable and economically positive initiatives.
Who must file Form 3468?
Generally, any organization that is subject to UBIT and has claimed investment credits must file Form 3468. This includes
- Businesses and Organizations: Entities that invest in qualifying rehabilitation, renewable energy, or advanced energy projects.
- Tax-Exempt Organizations with UBIT: Tax-exempt organizations filing Form 990-T can file Form 3468 if they have unrelated business income and meet the requirements for investment credits.
- Partnerships and Corporations: Partnerships, S-corporations, and corporations investing in qualifying projects must file Form 3468 to claim their investment credits.
