One last question : are there any consequences or future consequences of filing it out. For him and/or for me ? For example will he have to continue filing in the future.
No, there are no consequences for either of you. As a US citizen or US resident he is required to file a federal tax return each tax year if his income meets the minimum filing requirements. He would continue to file as Married Filing Separately if you do not have a SS number or ITIN issued by the IRS.
If his income does not meet the minimum requirements then no federal tax return needs to be filed.
