Questione giuridica chiave
Whether the spouses were taxable jointly or separately for direct federal tax in 2001
Decisione estratta
Separate taxation was refused because the requirements for tax-relevant separation were not cumulatively met.
Motivazione estratta
Although the spouses no longer shared a home, the taxpayer retained his tax residence at the marital domicile and the financial means for housing and support remained jointly used; an eheschutz order did not bind the tax authorities.
