Does it matter how long one works, when claiming a child on income tax?

Question

Is it just a base pay that everyone gets for claiming their child, or do they base it off how long you work?

Answer 1

The amount of an exemption and child tax credit is the same for everyone who owes enough taxes to take advantage of it, unless their income is above a certain level at which time these begin to phase out.

Answer 2

No it does not matter how long you worked that year as long as you worked you can get the child credit and maybe even earned income credit.
