Should I file jointly with my spouse?
If you are married, you are not allowed to file single. Your choices are to file jointly or separately - but you cannot claim you are single.
In 98% of cases - if you are both US citizens/GC holders, you are better off filing jointly (MFJ). There are rare instances where it makes more sense to file separately, but this is the rule of thumb.
If one spouse is not a US citizen, head of household (HOH) and married filing separately (MFS) are often used.

*Note: If you are filing a Non-resident return (1040NR), you will have to file separately.
