Casualty losses and theft are not deductible on your federal return since the tax laws changed for 2018 and beyond, so sorry--you cannot get a tax break for a stolen car. Hopefully you had insurance.
As for the sales tax on the car, if you are itemizing deductions like mortgage interest, etc. you can include sales tax as an itemized deduction.
SALES TAX
You can enter the sales tax you paid for the car you purchased in 2023 by going to Federal>Deductions and Credits>Estimates and Other Taxes Paid> Sales Tax. You will be asked if you paid sales tax on a major purchase, and you will be able to enter the sales tax you paid for your new vehicle.
Sales tax is an itemized deduction. Unless you have enough other itemized deductions to exceed your standard deduction the sales tax will have no effect on your tax due or refund.
“Major purchases” that you can enter for the sales tax deduction include:
Motor Vehicles (cars, trucks, motor homes, RV’s, sport utility vehicles and off-road vehicles
Aircraft or boats
Mobile homes
Manufactured housing
Building materials for major home improvements
You cannot deduct: furniture, jewelry, home electronics such as TV’s or computers
