Can I claim my husband as a dependent since he did not work last year

[xmasbaby0]

No.   A spouse can NEVER be claimed as a dependent.   File a joint return.  You can file a joint return even if one spouse had little or no income

. When you file a joint return, you and your spouse will get the married filing jointly standard deduction of $27,700 (+$1500 for each spouse 65 or older)  You are eligible for more credits including education credits, earned income credit, child and dependent care credit, and a larger income limit to receive the child tax credit.
