How do the income thresholds apply to my partnership’s purchase and use of a new clean vehicle

If a partnership or an S corporation places a new clean vehicle in service and the new clean vehicle credit is claimed by individuals who are direct or indirect partners of that partnership or shareholders of that S corporation, the modified adjusted gross income (AGI) thresholds apply to those partners or shareholders.

The relevant modified AGI thresholds are as follows:

• Married filing jointly or filing as a qualifying surviving spouse or a qualifying widow(er) — $300,000
• Head of household — $225,000
• All other taxpayers — $150,000

The modified AGI is the amount from line 11 of Form 1040 plus:

• Any amount on line 45 or line 50 of Form 2555, Foreign Earned Income.
• Any amount excluded from gross income because it was received from sources in Puerto Rico or American Samoa.

If the filing status changes between the preceding year and the current year, the partner or shareholder may claim the new clean vehicle credit if their modified AGI is less than or equal to the threshold applicable to their filing status for the preceding year or current year.
