Filing your taxes jointly will, in almost every situation, reduce the total tax bill for a married couple over married filing separately. There are several differences, many credits and deductions are limited for married filing separately. he main advantage of filing separately is that one spouse isn't liable for the other spouse's taxes. This could be a significant issue if the other spouse is hiding income, inflating deductions or simply not paying the taxes.
