What is 3468?
Form 3468, Investment Credit, is the Internal Revenue Service (IRS) form used to report information about a qualified facility or property and to compute an investment credit for it, attached to your tax return.
Part I collects the facility or property information: registration number, type, owner, address, coordinates, construction and placed-in-service dates, the prevailing wage and apprenticeship (PWA) answer, bonus credit answers and capacity. You then complete the part that matches your credit:
- Part II: qualifying advanced coal project credit (section 48A) and qualifying gasification project credit (section 48B).
- Part III: qualifying advanced energy project credit (section 48C).
- Part IV: advanced manufacturing investment credit (section 48D).
- Part V: clean electricity investment credit (section 48E).
- Part VI: energy credit (section 48), Sections A through N.
- Part VII: rehabilitation credit (section 47).
The IRS instructions say to complete a separate Form 3468 for each facility or property. The credit totals are reported on the matching lines of Form 3800, Part III. Form 7220, Prevailing Wage and Apprenticeship (PWA) Verification and Corrections, is filed for each facility or property when you claim the increased credit for meeting the PWA requirements under Part III, V or VI. A recapture of the credit is reported on Form 4255, Certain Credit Recapture, Excessive Payments, and Penalties. The form is OMB No. 1545-0155, Attachment Sequence No. 174.
Who needs to file 3468?
You use Form 3468 if you claim one of the investment credits it covers for a facility or property: the advanced coal project, gasification project, advanced energy project, advanced manufacturing investment, clean electricity investment, energy or rehabilitation credit.
- Partnerships, S corporations, estates and trusts attach a separate Form 3468 for each facility or property used in the business even if they cannot claim the credit, did not elect payment under section 48D(d), or did not elect a transfer under section 6418. They complete the required Part I lines and only the lines the instructions list, then attach a statement to Schedule K-1.
- Tax-exempt organizations and governmental entities that make an elective payment election under section 6417 for a section 48C, 48E or 48 credit attach Form 3468 and Form 3800 to Form 990-T or another applicable income tax return.
- Cooperative patrons file a separate Form 3468 to report unused investment credit allocated from cooperatives.
You cannot claim a credit for property used mainly outside the United States, used by a governmental unit or foreign person or entity (with exceptions), used for lodging, or certain MACRS business property expensed under section 179. You also cannot claim section 48C credits for a facility or property if you claimed credits under section 45X.
When to file 3468
Form 3468 is filed with the tax return for the year in which the credit is claimed; it has no separate due date. Each part figures the investment in property placed in service during the tax year, so the credit is reported on the return for that year.
If you intend to make an elective payment election or transfer election on Form 3800 for a credit in Part III, IV, V or VI, you must first complete the IRS pre-filing registration for each property or facility, before you file your tax return.
Watch the recapture period. The instructions say you may have to refigure and recapture all or part of the credit if you dispose of the property, or change its use, before the end of 5 full years after it was placed in service.

How to submit 3468
Form 3468 is not sent on its own: you attach it to your tax return. The instructions give no separate mailing address for it.
- With your return: attach the completed Form 3468, and Form 3800 where the instructions require it, to the return you file for the tax year.
- Individuals who e-file: if attachments are required for Form 3468, you must send a paper Form 8453, U.S. Individual Income Tax Transmittal for an IRS e-file Return.
- Tax-exempt and governmental entities: attach Form 3468 and Form 3800 to Form 990-T or the other applicable income tax return.

Elective payment and transfer elections require the IRS-issued registration number on Part I, line 1, obtained through the pre-filing registration at IRS.gov/Register. Attach the statements and forms the instructions require for your lines. FillingPDF lets you fill out and download the PDF; submission follows the channels above.
Common mistakes to avoid
- Combining several facilities or properties on one Form 3468; the instructions require a separate form for each facility or property.
- Skipping Form 3468 as a partnership, S corporation, estate or trust because the credit cannot be claimed; a separate form is still attached for each facility used in the business.
- Claiming a section 48C credit for a facility or property when you also claimed credits under section 45X for it.
- Checking line 7a or 8b to claim an increased credit without attaching the increased credit amount statement, or without Form 7220 where it applies.
- Checking line 9a or 9b for the domestic content bonus without attaching the domestic content certification statement at filing.
- Making an elective payment or transfer election without completing the pre-filing registration and entering the IRS-issued registration number on Part I, line 1.
- Completing the credit parts but not reporting the total on the matching line of Form 3800, Part III (for example Part V, line 11 to line 1v).
- Claiming the Part IV advanced manufacturing credit when construction of the qualified property begins after 2026; the instructions bar it.
- Using the address of the lessor's registered agent on line 13b instead of the lessor's principal office or place of business.
- Choosing to treat clean hydrogen property as energy property in Part VI, Section M while also taking the section 45V or 45Q credit.
