My husband didn't work this year how should I file

You can still 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.

If you are legally married and living together you should be filing as Married Filing Jointly even if one spouse had little or no income.
