EU workers, working here and paying tax & NI, who have a family with dependent children in their home country, can claim Child Ben here, if the home country do not pay an equivalent benefit. Child benefit international section say this is under Article 73, regs 1408/71, and that it is on the website ........somewhere.

Does this extend to Child tax credit as well...?

Art 73 of 1408/71 is on page 1150 of vol 3 of Soc Sec Legislation 2005.

It basically says that EU workers who have a family with dependent children in their home country, can claim "family benefits" here, if the home country do not pay an equivalent benefit.

The question would seem to be whether CTC is a "family benefit". "Family benefit" is defined at Article 1(u)(i) as "all benefits in kind or in cash intended to meet family expenses". CTC must fit into that definition, so probably the rule does apply to CTC.
