Form 8609-A tells the IRS whether a building still qualifies for the low‑income housing credit and figures the credit amount for that tax year. Owners must answer questions about the original credit award, any basis reductions, and compute the credit using the eligible basis from Form 8609.
The building owner must file IRS Form 8609-A for each year of the 15‑year compliance period.
The form collects the building identification number, confirmation that the original Form 8609 is on file, whether the building qualified under section 42, any decrease in qualified basis, and computes the credit using eligible basis and credit percentage lines.
First, complete Part I by entering the building identification number from Form 8609 and answering three yes/no questions about the original Form 8609, qualification under section 42, and any decrease in qualified basis. If any answer is “No” as directed, stop and do not proceed to Part II. If all answers allow continuation, move to Part II and compute the credit, starting with the eligible basis from Form 8609 line 7 and applying any high‑cost area adjustments, then enter the credit percentage from Form 8609 Part I line 2 on line 5. The form must be signed before filing.
Because the credit may be fully claimed after the 11th year, the instructions say not to complete Part II. Verify the credit has not been fully claimed; if after 11th year, omit Part II per Instructions p.1.
