The best way to file is a Joint return. Joint is one return combined for the both of you. A spouse is never a dependent. You file a Joint return and get a personal exemption for each of you. An exemption is the same as claiming a dependent.
You will have to report their Social Security on your Joint return. It might be taxable or not. Up to 85% of Social Security becomes taxable when all your other income plus 1/2 your social security, reaches:
Married Filing Jointly: $32,000
Single or head of household: $25,000
Married Filing Separately: 0
