Basically we are both very low earners. He doesn't work with me or at my place and he files tax as self employed. It is hard for me how to fill the form and my husband doesn't know much about tax . I am soon doing my first job in US and so I had never filed any tax before as I had no job in US. So when I file income tax, his income is automatically included in my tax form and he doesn't have to go to tax preparer like he used to to file income tax for himself ? or regardless of what I write, married, single or jointly, we both have to file our own yearly income tax separately? what letters or numbers I write in W4 JOb tax form? advice please! .What is best for us? single filing, married jointly or separately? If I say married file jointly in job W4 FORM, What does this mean? His income will still be low like about $5K. My husband filed tax last year and
