If you are referring a tax credit beginning in 2024, you can opt for transferring the clean vehicle credit directly to an automotive dealer instead of waiting to claim it on your tax return the next year.
If you do have a refundable credit you will get that refund when you file your 2024 tax return.
Also if you itemize deductions you will include the vehicle sales tax and other qualifying expenses, such as state and local income and property taxes, mortgage interest, charitable contributions and medical expenses.
If you use your vehicle for business you may be eligible for vehicle depreciation in your deduction and or mileage/other expenses if applicable.
