if separated and filing as single do i have to report spouses healthcare.cov info

[DoninGA]

If you are legally married you cannot file as Single.  You can file as Married Filing Jointly or Married Filing Separately.

If you file as Married Filing Separately you do not enter any income or expenses for you spouse on your tax return.  No, you do not their healthcare.gov info.

I agree with @DoninGAif if you live in a community property state, you must allocate income and deductions 50/50. Regardless, though, if you share your marketplace coverage with your spouse and are on the same policy at any point during the year, you must "allocate" the policy amounts between your two separate returns.  

This is true regardless of whether you live in a community property state or not.
