Do I mark my wife as dependent if I make the only income in our home ??

A spouse is never a dependent. When you file jointly you get a greater standard deduction.

@arivas1269 NO.   A spouse is never claimed as a dependent.  File a joint tax return.

Married Filing Jointly is usually better, 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 $25,900 (+$1400 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.
