The Low-Income Housing Tax Credit Program is a vital tool for addressing affordable housing needs in the US. It's a federal program that provides tax credits to developers who build and renovate affordable housing.
Developers can claim these tax credits over a 10-year period, which helps offset the costs of construction and operation. This program has been instrumental in creating over 2.5 million affordable housing units since its inception.
The program has been successful in part because it allows developers to sell the tax credits to investors, generating much-needed capital for affordable housing projects. This model has been adopted in many states and has helped to fund thousands of affordable housing developments.

What is LIHTC
LIHTC stands for Low-Income Housing Tax Credit, a program that provides tax credits to developers who build affordable housing.
The program was created in 1986 as part of the Tax Reform Act, with the goal of increasing the availability of affordable housing.
Developers who receive LIHTC funding are required to rent at least 20% of their units to low-income families.
These units are typically rented at a reduced rate, often 30% or less of the area median income.
Application and Qualifications
To apply for the Low-Income Housing Tax Credit program, you'll need to submit an application to a state authority, which will review it competitively. The application should include estimates of the project's expected cost and a commitment to comply with one of the set-asides.
The set-asides are conditions that ensure a certain percentage of the residential units are rent restricted and occupied by low-income individuals. There are three options: 20/50, 40/60, and income averaging. The 20/50 option requires at least 20% of the units to be rent restricted for individuals earning 50% or less of the area median gross income. The 40/60 option requires at least 40% of the units to be rent restricted for individuals earning 60% or less of the area median gross income.
To be eligible to rent in a tax credit property, households must have incomes that do not exceed 60% of the median income based on family size and county location. Rents are capped to remain affordable to families earning less than 60% of median income.

Applicant Qualifications
The applicant qualifications for the LIHTC program are straightforward. Both nonprofit and for-profit developers may apply.
To be eligible, developers must be willing to offer a certain percentage of their units to low-income tenants. This can be done through a "set-aside" commitment, which guarantees a minimum number of units will be rent restricted and occupied by individuals whose income is below a certain threshold.
The LIHTC program allows both corporate and private investors to receive a fair return on their investment in affordable housing. This makes it an attractive option for those looking to invest in a socially responsible way.
In terms of specifics, developers must agree to a higher percentage of low-income usage than the minimums, which are 20% or more of the residential units for rent restricted units occupied by individuals whose income is 50% or less than the area median gross income, and 40% or more for units occupied by individuals whose income is 60% or less than the area median gross income.
Developers may also choose to offer income averaging, which allows them to set aside units for tenants whose income does not exceed the imputed income limitation designated by the taxpayer, as long as the average of these limitations does not exceed 60% of the area median gross income.
Acquisition

Acquisition is a crucial step in the process, and it's essential to understand the different types of acquisition credits available.
The Acquisition Credit is $1,600, as seen in Example 1. This credit is a significant amount that can be used to offset the costs of acquiring a property.
For buildings and land, the acquisition cost is $120,000, but this includes the value of the land, which is $20,000.
The qualified basis for acquisition is $40,000, which is calculated by subtracting the value of the land from the total acquisition cost.
The applicable credit percentage for acquisition is 4%, which is applied to the qualified basis to determine the acquisition credit.

Impact and Evaluations
The Low-Income Housing Tax Credit (LIHTC) program has been extensively evaluated and studied over the years. The President's Economic Recovery Advisory Board (PERAB) estimated that the program would cost the federal government $61 billion in lost tax revenue from 2008-2017.
Experts believe that vouchers would be a more cost-effective way to help low-income households. A 2018 report by the GAO found that the LIHTC program financed about 50,000 low-income rental units annually, with median costs per unit ranging from $126,000 in Texas to $326,000 in California.

The range of per-unit costs varied dramatically, with California having the highest variance of $606,000 between the least expensive and most expensive per-unit cost. In contrast, Georgia had the lowest variance of $104,000.
Here's a breakdown of the average costs per unit by project size and location:
A 2022 study found that LIHTC projects increase land value in surrounding neighborhoods.
LIHTC and 2008 Financial Crisis Impact
The 2008 financial crisis had a significant impact on the Low-Income Housing Tax Credit (LIHTC) program. $2.25 billion was allocated to the HOME Investment Partnerships Program for a grant program to provide funds for capital investments in LIHTC projects.
State housing credit agencies were awarded Tax Credit Assistance Program (TCAP) grants to facilitate development of projects that received LIHTC awards between October 1, 2006, and September 30, 2009. The grants were allowed to be offered in either a grant or loan form to the properties.
The Department of Treasury estimated outlay to States was $3 billion for 2009. State housing agencies were required to use a grant to make sub-awards to finance the acquisition or construction of qualified low-income buildings.
Recent Congressional legislation proposed expanding this program to 2010 housing credits.

Evaluations and Studies
The LIHTC program has undergone extensive evaluations and studies to assess its effectiveness and impact. A 2010 report by the President's Economic Recovery Advisory Board estimated that the program would cost the federal government $61 billion in lost tax revenue from participating corporations from 2008-2017.
The Government Accountability Office (GAO) conducted a report in 2018, covering the years 2011-2015, which found that the LIHTC program financed about 50,000 low-income rental units annually. The median costs per unit for new construction ranged from $126,000 in Texas to $326,000 in California.
Some notable findings from the GAO report include the dramatic variation in per-unit costs across different states. For example, the range of per-unit costs varied dramatically, with Georgia having the lowest variance of $104,000, while California had the highest variance of $606,000.
Here's a breakdown of the per-unit cost variances across different states:
Larger projects with more than 100 units were found to be about $85,000 less expensive per-unit than smaller projects with fewer than 37 units. Additionally, urban projects cost about $13,000 more per-unit than non-urban projects.
A 2022 study found that LIHTC projects increase land value in surrounding neighborhoods, which is a positive outcome for the program. However, a 2018 report by the Urban Institute criticized the program's lack of permanent affordability requirements and questioned whether it fully meets the needs of the poorest households.
Program Function and Allocation
The Low-Income Housing Tax Credit program is designed to provide tax credits to developers who agree to maintain a certain percentage of rental housing as income restricted for at least 18 years.
Each state has an annual tax credit authority, with Michigan's being approximately $20 million. This authority is based on $2.00 per state resident.
The tax credit allocation process involves three stages: reservation, commitment, and allocation of credit. The final determination of how much credit will actually be awarded is made at the allocation stage.
The tax credit percentage is roughly 9% of the qualified basis of construction or rehabilitation costs for developments not utilizing federal or tax-exempt financing. For developments that do utilize federal or tax-exempt financing, the tax credit percentage is roughly 4% of the qualified basis.

Program Function
The tax credit program requires that a minimum of 20 percent of units be for residents whose incomes do not exceed 50 percent of area median income, or 40 percent of units for residents whose incomes do not exceed 60 percent of area median income.

In order to qualify for the tax credit, a project must agree to maintain a certain percentage of rental housing as income restricted for at least 18 years.
The maximum tax credit a project may receive is based on a percentage of the portion of rental housing that is income restricted.
An annual credit equal to roughly 9 percent of the qualified basis of construction or rehabilitation costs is available to developments not utilizing federal or tax-exempt financing.
The Allocation Process
Each state has an annual tax credit authority equal to $2.00 per state resident, which can add up to a significant amount.
Michigan's annual authority is approximately $20 million.
The process used to evaluate applications and allocate credit involves three stages: reservation, commitment, and allocation of credit.
The final determination of how much credit will actually be awarded is made at the allocation stage.
Applicable Credit Percentage is x 9%.
Here's a breakdown of the conditions that project owners must agree to in order to receive tax credits:
- At least 20% or more of the residential units in the development are both rent restricted and occupied by individuals whose income is 50% or less than the area median gross income ("20/50").
- At least 40% or more of the residential units in the development are both rent restricted and occupied by individuals whose income is 60% or less than the area median gross income ("40/60").
- At least 40% or more of the residential units in the development are both rent restricted and occupied by individuals whose income does not exceed the imputed income limitation designated by the taxpayer with respect to the respective unit. The average of the imputed income limitations shall not exceed 60% of the area median gross income ("income averaging").
Rehabilitation
Rehabilitation is a key aspect of this program, offering financial incentives to property owners and developers.
The Rehabilitation/Acquisition Expenses can be subsidized up to 40% for low-income units.
For low-income units, the Acquisition Credit can be up to $1,600.
Rehabilitation Credit is also available, providing a significant financial boost to those undertaking rehabilitation projects.
The Annual Rehab Credit can be as high as $7,200, with a Total Annual Credit of $8,800.
This credit can be claimed over a period of 10 years, resulting in a Total Credit of $88,000.

Tax and Compliance
To be eligible for Low-Income Housing Tax Credits, developers must submit an application for each rental property, agreeing to keep rents affordable for a period between 15 and 30 years for families and individuals with incomes at or below 80% of the local median income.
The tax credit is available each year for 10 years, as long as the property continues to operate in compliance with program regulations. This allows owners to lower the amount of the property's debt financing by exchanging the tax credits for equity investments from major financial institutions.
Compliance is crucial, as selection criteria for Housing Credits include factors such as project location, market demand, and ability to serve the lowest-income tenants. If you're a new developer, partnering with a successful developer is essential to increasing your chances of being selected.
Here are the key selection criteria for Housing Credits:
- Project location and site suitability.
- Market demand and local housing needs.
- Ability to serve the lowest-income tenants.
- Ability to serve qualified tenants for the longest periods.
- Design and quality of construction.
- Financial structure and long-term viability.
- Experience of development team and management agent(s).
- Ability to serve persons with disabilities and the homeless.
- Projects that are part of a Community Revitalization Plan.

Tax Break for Housing Investors
The Low Income Housing Tax Credit Program is a tax incentive for housing investors, created by the federal Tax Reform Act of 1986.
Developers can claim a tax credit equal to approximately 9% of the "Qualified Cost" of building or rehabilitating a property, which can be exchanged for equity investments from major financial institutions.
This lowers the operating costs and makes it economically feasible to operate the property at below-market rents.
