The SBI tax return must be filed with the regular income tax return to be accepted. If the taxpayer does not file both returns together, the election may be denied and the adjustment to federal adjusted gross income may be disallowed.

File Form 140 and Form 140-SBI with the same filing status. If filing married filing separate returns, enter the name and social security number of the spouse. If filing married filing joint returns, include all income.
