First, you need to have received a letter from West Virginia. The letter is called "MV-1." This letter will be used to claim the credit on your tax return.
Here's how to do this in TurboTax Online:
Navigate to State Taxes > Your State Returns > West Virginia> Continue
Continue through the interview screens until you come to "Motor Vehicle Property Tax Adjustment Credit", answer "Yes"
Add a Form MV-1 and enter the information from your letter.
If you don't receive the MV-1 letter by February 15, 2025, go to MyTaxes and request another Motor Vehicle Property Tax letter.
