Generally, filing jointly
together with your spouse will give you a bigger refund or less taxes due.
When you file separately, your tax rate is higher, and you won't be able to
claim certain deductions or credits. However, there are a few exceptions, in which it is more advantageous to file separately. Please see the following TurboTax FAQ,
