As a general rule, Married-Filing Jointly is the best approach for taxes. Several tax credits and deductions are not available to married couples filing separately (see the TurboTax article link, below).
Without specific numbers (which we are not permitted to accept or work with) there is no way to tell whether filing married-jointly or married-separately would result in a better overall tax outcome for you. When you add in the variables of state tax, the problem becomes much more complicated.
TurboTax has an excellent article that addresses several consideration when asking Is it better for a married couple to file jointly or separately?
