Can I make a contribution to a traditional IRA in order to reduce my tax liability?

My husband and I are both eligible to participate in our employers' 401k plans but are not participating.

It will depend on your income.  If you have over 121,000 of modified adjusted gross income, your deduction can be limited or phased-out.  Whether or not you actually contribute to your 401(k) doesn't matter.  What matters is that your employer has a plan, and that limits your income for the purpose of the deduction.
