Question: can u claim a 1 month old on taxes?
Answer: 31. It's possible to claim your baby as a dependent as long as they were born at any time during the tax year—even if it's 11:59 p.m. on the last day of the year. 1﻿ But if they wait until 12:01 a.m. on Jan. 1 to arrive, you're out of luck—at least until you file that year's tax return.
