IRS Form 8609, Low-Income Housing Credit Allocation and Certification, is used by property owners to claim the Low-Income Housing Tax Credit (LIHTC) for residential rental buildings that qualify under Section 42 of the Internal Revenue Code. This form is issued by a state or local housing credit agency to property owners, certifying the building’s eligibility for the tax credit. The form includes crucial details like the Building Identification Number (BIN), applicable credit percentage, and the maximum allowable credit amount. Property owners must complete Part II (First-Year Certification) in the first year of claiming the credit. LIHTC incentives encourage the development of affordable rental housing by providing a tax break over a 10-year period. Owners must ensure compliance with set-aside requirements and rent restrictions to retain eligibility. Failure to meet compliance rules may result in credit recapture, requiring Form 8611, Recapture of Low-Income Housing Credit. Property owners must keep accurate records, including Forms 8586, 8609-A, and 8611, to ensure compliance and avoid penalties.
