Schedule A (Form 8038-CP): Specified Tax Credit Bonds Credit Computation
Schedule A (Form 8038-CP), Specified Tax Credit Bonds Credit Computation, is attached to Form 8038-CP, Return for Credit Payments to Issuers of Qualified Bonds. The form says it is completed for Form 8038-CP, line 17c, bond types 102, 103, 104 and 105, and is used when claiming a credit under section 6431 for specified tax credit bonds: new clean renewable energy bonds (NCREBs), qualified energy conservation bonds (QECBs), qualified zone academy bonds (QZABs) and qualified school construction bonds (QSCBs).
The instructions say Schedule A computes the amount of the refundable credit payment allowed under former section 6431(f), bond by bond, which usually means a separate computation for each maturity in a bond issue. The total from line 3 goes on Form 8038-CP, line 19c. The instructions also say Schedule A eliminates the need for issuers of NCREBs and QECBs to file separate Forms 8038-CP for each maturity on each interest payment date.
This page has the December 2022 revision, which the instructions name as the version to use. The PDF can be filled out free in the browser on this page and downloaded without an account.
What's on Schedule A (Form 8038-CP)
Columns (a) to (c)
Column (a) is the bond maturity date. Column (b) is the interest payable on that maturity on the line 18 date. Column (c) is the interest figured at the line 19b applicable credit rate.
Columns (d) and (e)
The form says column (d), for NCREBs and QECBs, multiplies column (c) by 70% (0.70). Column (e) takes the smaller of (b) or (d) for NCREBs and QECBs, or the smaller of (b) or (c) for QZABs and QSCBs.
Lines 1 to 3
Line 1 totals column (e) on page 1, line 2 brings in the page 2 total, and line 3 adds them for Form 8038-CP, line 19c.
Page 2 continuation and line 4
Page 2 repeats the table for more maturities, starting with the first maturity after the last row on page 1. Line 4 totals its column (e) for page 1, line 2.

Where it goes, timing and assembly
Attach to Form 8038-CP
The form says "Attach to Form 8038-CP." The instructions say to assemble the core form first, then Schedule A, then any attachments.
When Form 8038-CP is filed
For fixed rate bonds, the instructions say Form 8038-CP is filed no later than 45 days before the relevant interest payment date and not earlier than 90 days before it. Variable rate bonds have their own timing rules.
Electronic filing
The instructions say a filer required to file at least 10 returns of any type during the calendar year files Forms 8038-CP electronically starting in 2024. Others may file electronically voluntarily.
Paper returns
For paper returns, the instructions give this address: Department of the Treasury, Internal Revenue Service Center, Ogden, UT 84201-0050.
One bond type per return
The instructions say to file a separate Form 8038-CP with a Schedule A for NCREBs, QECBs, QZABs and QSCBs, and that mixing bond types on one return could delay the credit payment.
Use the right version
The instructions say to use the December 2022 version of Schedule A with the January 2022 version of Form 8038-CP, and that a prior version could delay the credit payment.
