If your organization issues or transfers bond tax credits, you’re required to report them using IRS Form 1097-BTC. This form is used to report the allocation of tax credit bonds, such as Build America Bonds or Qualified Energy Conservation Bonds. Filing accurately and on time ensures proper credit tracking and IRS compliance.
Form 1097-BTC, is an information form used to report bond tax credits to the IRS annually and to bond holders or investors on a quarterly basis. This form provides information including CUSIP number, type of bond the bond holder has invested in, the total credits and monthly credits. The bond holder can use these credits while filing federal taxes.
Who must file Form 1097-BTC?
Bond Issuers or agents such as brokers, nominees, mutual funds, or partnerships must file copy A of this form with the IRS to report the tax credits distributed. The issuers of bonds will send a copy B to the bond holder if they receive a tax credit of at least $10 directly or indirectly from a tax credit bond or a stripped credit coupon during the tax year.
Types of tax credit bonds
Credit distributed from the following tax credit bonds must be reported on this form.

Select only one box that describes the issuer:

Check the second box if you are an entity or individual who has received (or should have received) a current year Form 1097-BTC and you are now distributing part or all of that credit to others.
Enter the calendar year to report when the bond tax credits were issued.
Box 1

Box 2a
Enter the unique identification number code:

Box 3
For clean renewable energy bonds, enter code "101" and for all other bond types, enter code "199."
Note: Multiple bond types can be reported on a single Form 1097-BTC, except for clean renewable energy bonds. Bond credits for clean renewable energy must be reported on a separate 1097-BTC Form.
Box 4
Reserved for future use.
Boxes 5a-5l
Report the monthly bond tax credits allowed to the recipient for each month of the calendar year. Here’s how to calculate the credit:
STEP 1:
For Qualified tax credit bond, Clean renewable energy bond, or Qualified zone academy bond (issued before October 4, 2008)
calculate the credit by multiplying the outstanding face amount of the bond by the applicable credit rate.
Outstanding face amount = Original face value – Principal amount that has been repaid
Qualified Zone Academy Bonds (Issued Before July 1, 1999):
Calculate the Credit rate by multiplying 110% (or 1.10) by the long-term Applicable Federal Rate (AFR). AFR is published monthly by the IRS in the Internal Revenue Bulletin.
Build America Bond
Calculate the Credit rate by multiplying 35% (or 0.35) by the interest payable on the interest payment date. Enter the amount in boxes 5a–5l for the month in which the interest payment occurred.
Example:
If the bond pays interest on June 30 and December 31, the credit amounts should be entered in box 5f (June) and box 5l (December).

Clean renewable energy bond or Qualified tax credit bond
If the clean renewable energy bond or qualified tax credit bond is issued, redeemed, or matured in the middle of 3-month period, instead of getting the full 25% credit for that quarter, credit will be prorated based on how many days the bond was active during those 3 months.
Example 2
A qualified zone academy bond that issued matures on March 23, 2025. The bond is not outstanding for the entire 3-month period ending June 15, 2025, then you must prorate the 25% by dividing the number of days the bond was active by total number of days.
Proration Calculation = 8 days (number of days from March 16 through March 23) / 92 days
(number of days from March 16 through June 15)
= 0.087 x 0.25 = 2% (0.02)
For the Second Quarter, the credit allowance date is June 15, 2025. Enter the amount in box 5f by multiplying 2% (0.02) with STEP 1 amount. For annual reporting, enter in box 1 "27%" (0.27) of the amount determined in STEP 1.
