Low-Income Housing Tax Credit (LIHTC): Property Level Data

    Dataset/Low-Income Housing Tax Credit (LIHTC): Property Level Data

HUD's LIHTC database contains information on 53,032 projects and 3.65 million housing units placed in service between 1987 and 2022. Data for properties placed in service in 2023 will be collected in the fall of 2024 and added to this database in the spring of 2025. The database includes project address, number of units and low-income units, number of bedrooms, year the credit was allocated, year the project was placed in service, whether the project was new construction or rehab, type of credit provided, and other sources of project financing. The database has been geocoded, enabling researchers to look at the geographical distribution and neighborhood characteristics of tax credit projects. It may also help show how incentives to locate projects in low-income areas and other underserved markets are working. With the continued support of the national LIHTC database, HUD hopes to enable researchers to learn more about the effects of the tax credit program.


 

ACCESS LIHTC DATA

All LIHTC data are available through the interactive system for accessing the LIHTC Database at https://lihtc.huduser.gov/. Users may select variables of interest, retrieve data on all projects in a particular State or group of States, restrict the search to projects with a particular characteristic or set of characteristics, select only projects in a particular city or county, or all projects within a user-selected radius of the center of a city.

Alternatively, you can download the entire database. The file, LIHTCPUB.ZIP, is a ZIP archive file containing the following:

LIHTC Data Dictionary 2022.PDF The data dictionary for the LIHTC database (multiple address data use same formats) in Adobe Acrobat.
LIHTCPUB.ACCDB The LIHTC Database in MS Access format. This file also includes building addresses from HUD’s LIHTC tenant data collection.
LIHTCPUB.CSV The LIHTC Database in CSV format.

See the data dictionary for the definitions of each variable.

REVISIONS TO THE LIHTC DATABASE

In late 1996, additional efforts were made to improve the coverage of the LIHTC database for earlier years of the program. These efforts resulted in the addition of 1,989 projects containing 67,056 units to the database. When this revision was first posted in October 1997, the text file LIHTCPUB.TXT containing the entire database was inadvertently created without decimals (i.e., all numerical fields were integer only affecting the tract number, latitude, longitude, and several census data fields). The Excel files were not so affected. The only effect of the January 1998 revision is to correct this error in the LIHTCPUB.TXT file. The Excel files were not revised. Note that the report, Development and Analysis of the National Low-Income Housing Tax Credit Database, has NOT been revised to reflect the additional data.

In January 2001, data for projects placed in service between 1995 and 1998 were added. These projects are described in the report Updating the National Low-Income Housing Tax Credit Database. Except for some additional geocoding, there were no revisions made to data for projects placed in service from 1987 through 1994.

In May 2002, data for projects placed in service through 1999 were added. This also included 319 projects and 25,000 units placed in service in 1998 and 44 projects and nearly 5,000 units placed in service in 1997 that were not included in the previous update.
