If I had a written agreement on 3/30/22 that I put a significant deposit down for a EV I acquired on 11/19/22 how do I claim the credit since the dates cause issues.

"In service" date means the date you've taken delivery of the purchased vehicle, so that date can't be earlier than the contract or order date. That could be the issue.

I am only given two date fields:

1. Date Acquired:
2. Date In Service:

Should I use Date Acquired as Contract Date and Date in Service as Delivery Date then?

Yes, the date acquired is the date you purchased, or entered into a written binding contract to purchase.  The Date In Service is when you received the vehicle.  

If you purchased, or entered into a written binding contract to purchase, a qualified plug-in electric drive motor vehicle after 2021 and before August 16, 2022, you may elect to treat such vehicle as having been placed in service on August 15, 2022, the day before the enactment date of the Inflation Reduction Act of 2022.

Thanks for the clear definition of date acquired--seems simple but I didn't see it on any of the forms.  I'll raise a glass to you if/when my rebate clears!
