Do I need to file my taxes if my spouse filed jointly?

[xmasbaby0]

No.  If your spouse correctly prepared and filed a joint tax return that had all of your combined income, credits, deductions, etc. etc. etc. on the joint return, then you do not have anything else to do.   When you file jointly, it is all on the same tax return and the refund will have both names on it--or the tax due is owed by both spouses.

If you are asking if you have to file your own tax return if you have already filed jointly with your spouse, the answer is No.

A joint return is filed by both spouses to report the combined income, deductions and credits from both spouses. Both spouses are equally responsible for the taxes owed.

A joint return usually results in a lower tax tax bill.
