Kernrechtsfrage
Whether the spouses were taxable jointly or separately for direct federal tax in 2001
Extrahierter Entscheid
Separate taxation was refused because the requirements for tax-relevant separation were not cumulatively met.
Extrahierte Begründung
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.
