C. Where husband and wife have not separately reported and claimed items of income, exemptions and deductions for federal income tax purposes, and have not elected to file a joint Virginia income tax return, such items allowable for Virginia income tax purposes shall be allocated and adjusted as follows:
3. Nonbusiness deductions, where properly taken for federal income tax purposes, shall be allowable for Virginia income tax purposes, but shall be allocable between husband and wife as they may mutually agree. For this purpose, “nonbusiness deductions” consist of allowable deductions not described in subdivision 2 of this subsection.
4. Where the standard deduction or low income allowance is properly taken pursuant to subdivision D 1 a of § 58.1-322 such deduction or allowance shall be allocable between husband and wife as they may mutually agree.
5. Personal exemptions properly allowable for federal income tax purposes shall be allocated for Virginia income tax purposes as husband and wife may mutually agree; however, exemptions for taxpayer and spouse together with exemptions for old age and blindness must be allocated respectively to the spouse to whom they relate.
D. Where allocations are permitted to be made under subsection C pursuant to agreement between husband and wife, and husband and wife have failed to agree as to those allocations, such allocations shall be made between husband and wife in a manner corresponding to the treatment for federal income tax purposes of the items involved, under regulations prescribed by the Department of Taxation.
