This page allows you to generate Low-Income Housing Tax Credit (LIHTC) Qualified Census Tract (QCT) tables for individual counties, individual metropolitan areas, nonmetropolitan parts of individual States, all counties in a single State, the complete table for all metropolitan areas, and the complete table for all nonmetropolitan parts of States. Simply click the appropriate button below.
Geocoded lists of all Qualified Census Tracts are available in WinZip-archived dBase files. | 2015 | 2016 |
The 2016 QCTs are based on MSA definitions published in OMB Bulletin No. 10-02 on December 1, 2009 and data from the 2010 Decennial Census and three sets of 5-year tabulations of the American Community Survey (2007 to 2011; 2008 to 2012; and 2009 to 2013). The Census Tract boundaries are according to the 2010 Decennial Census. See the latest Designation Notice for complete information.
Excel spreadsheets containing the data used to designate the 2016 QCTs are available here. The designation algorithm can be read here.The Complete Metro Table is available as an Adobe Acrobat (*.PDF) file formatted for optimal printing. | 2015 | 2016 | The Complete Nonmetro Table is available as an Adobe Acrobat (*.PDF) file formatted for optimal printing. | 2015 | 2016 |
Effective date: The effective date of the 2016 QCTs and DDAs is July 1, 2016. The 2015 DDA designations remain in effect through June 30, 2016. The 2016 Notice also extends from 365 days to 730 days the period for which the 2016 lists of QCTs and DDAs are effective for projects located in areas not on a subsequent list of DDAs or QCTs but having submitted applications while the area was a 2016 QCT or DDA. The same extension applicable to the 2015 QCTs and DDAs will be punblished in separate notice.
Metropolitan DDAs: As previously announced,beginning with the 2016 designations, HUD is designating metropolitan DDAs by ZIP code, rather than for an entire metropolitan area. The non-metropolitan DDAs continue to be designated by county.
Information on Small Difficult Development Areas (SDDAs):
While the geographic extent of ZCTAs is very similar to current 5-digit ZIP codes, and the vast majority of ZIP Code areas remain fixed over time, the U.S. Postal Service (USPS) may alter specific ZIP code geography at any time after HUD designates SDDAs. The data from which SAFMRs and SDDA designations are derived, however, does not immediately shift with the USPS definition of ZIP Codes, but remains defined by the ZCTAs as established by the Census Bureau. Therefore, for purposes of determining 2016 SDDA status, users should refer to the DDA (ZCTA) address locator at http://www.huduser.gov/portal/sadda/sadda_qct.html rather than the USPS-assigned 5-digit ZIP Code of the project.
The designation methodolgy of the 2016 non-metropolitan DDAs, defined at the county-level, remain unchanged.
The Difficult Development Area tables are available as Adobe Acrobat (*.PDF) files formatted for optimal printing.
