When was the sixteenth amendment ratified?

Answer 1

Never. In order for an amendment to be properly ratified, it must be ratified in its EXACT language, by 3/5 of all of the states. While it seems that enough states did ratify a variation of the amendment in some form or another, it was never ratified in its exact language by enough states.

This did not, however, prevent it from being added to the Constitution, and becoming de facto "law".

It was never properly ratified.

The 16th Amendment to the US Constitution was passed by Congress on July 2, 1909 and officially ratified on February 3, 1913 when Delaware became the 36th state to ratify the amendment. A total number of 42 of the 48 states which existed at that time ratified the 16th Amendment.
