When do I claim the solar tax credit for new build home I purchased including solar installation in 2024 but house was completed in 2025 and we moved in this month.

You can claim the solar tax credit for the year the solar installation was completed and the system was placed in service. Since your house was completed and you moved in this month (March 2025), you should claim the credit on your 2025 tax return.

Here's how to report it in TurboTax:

1. Open Your Return: Start by opening your tax return in TurboTax.
2. Navigate to the Home Energy Credits Section: Use the search box (magnifying glass at top right of screen)  and type " residential energy credits" and click the "Jump to" link.
3. Enter Your Information: Follow the interview prompts to enter the details of your solar installation, including costs and installation date
4. Form 5695: TurboTax will automatically generate Form 5695, Residential Energy Credits, based on your input

For more detailed guidance, you can refer to the TurboTax support article on claiming the solar tax credit
