Should I file separately?

Article ID: IAS10382
The main reason you'd want to file separately is to protect yourself from inaccurate tax information reported by your spouse. When you file separately, you are only responsible for the accuracy and payment of taxes on your own return.
If you're trying to save on your taxes, forget it; many deductions and credits available to joint filers are unavailable when filing separately.
