If a spouse had not owned a home within the past three years, could that spouse qualify as a first-time homebuyer for the credit even though the wife would not qualify?
No. The purchase date determines whether a taxpayer is a first-time homebuyer. Since the wife had ownership interest in a principal residence within the prior three years, neither taxpayer may take the first-time homebuyer credit. Section 36(c)(1) of the Internal Revenue Code requires that the taxpayer and the taxpayer’s spouse not have an ownership interest in a principal residence within the prior three years from the date of purchase. The husband may not take the credit even if he filed on a separate return.
