The Internal Revenue Service published Notice 2019-19, which provides population figures to use in calculating 2019 volume limits for the low-income housing tax credit (LIHTC) and private activity bonds (PABs). The LIHTC cap is the greater of the population multiplied by $2.75625 or $3,166,875 and the PAB cap is the greater of the population multiplied by $105 or $316,745,000. NH&RA estimates of 2019 LITHCs are available here.
