Why is the tax information missing from 2016 ASEC?

The tax fields (CTCCRD, ACTCCRD, ADJGINC, EITCCRED, FEDTAX, etc.) are all unavailable from the 2016 ASEC.

Is this because this information was never collected/imputed by Census?

Or because it exists but hasn’t been updated yet?

Thank you!

A number of variables indicating noncash benefits and after-tax values are temporarily withheld from the 2016 ASEC public use file until reports on alternative income and poverty measurements are published. The Census Bureau re-released the 2016 ASEC file with these origionally withheld variables on October 13th. IPUMS-CPS expects to release the corresponding update within the next 3 weeks. More information about the 2016 ASEC can be found in the codebook found here.
