IRS Form 1097-BTC – Bond Tax Credit – Tax credit bonds have long been a tool for funding public infrastructure and renewable energy projects, offering investors direct credits against their federal tax liability instead of taxable interest. But with issuance authority for most types expired after 2017, ongoing compliance for outstanding bonds remains essential. IRS Form 1097-BTC—Bond Tax Credit—is the information return that reports these credits to the IRS and recipients, ensuring accurate claims on tax returns. For calendar year 2025, issuers must furnish quarterly statements and file annually by March 31, 2026, if e-filing, with penalties up to $330 per form for late submissions. This SEO-optimized guide, based on the April 2025 revision (Cat. No. 54293T), covers filing requirements, deadlines, and step-by-step instructions to help issuers, agents, and recipients navigate Form 1097-BTC efficiently.
What Is IRS Form 1097-BTC?
IRS Form 1097-BTC reports tax credits allowed to holders of specified tax credit bonds, enabling them to claim nonrefundable credits on Form 1040, 1120, or other returns under IRC Sections 54A through 54F. Issued by bond issuers (e.g., states, localities) or their agents (e.g., trustees), the form details quarterly credit allowances—typically 25% of the annual credit—based on the bond’s outstanding principal. It’s an information return, not a payment form, but failure to file triggers IRS matching and potential audits.
Key purposes:
- Credit Allocation: Tracks quarterly credits (March 15, June 15, September 15, December 15) for bonds held during allowance periods.
- Recipient Reporting: Provides data for claiming credits, reducing tax liability dollar-for-dollar.
- Intermediary Passthrough: Mutual funds, partnerships, or RICs use it to distribute credits to shareholders or partners.
The April 2025 revision introduces continuous use and online fillable PDFs due to low paper volume, per General Instructions for Certain Information Returns. Download the form and instructions from IRS.gov/Form1097BTC.
