FMLA allows up to 12 weeks unpaid leave for birth/adoption. Unpaid leave has no tax implication. However, if employer pays "parental leave" income, it's taxable (W-2 wages). Short-term disability payments for childbirth may be non-taxable if policy is employee-paid; taxable if employer-paid. Consult payroll about tax treatment of leave pay.

A new dependent does not increase the parents' standard deduction, but child-related credits may reduce expected tax and change the appropriate Form W-4 entries. Submit a revised W-4 if the estimate shows that your current withholding is no longer appropriate.
