Hello lfs60,
Thank you for participating in our ask the expert event.
The Inflation Reduction Act, does not require any additional form for Senior or any other tax payer by itself. Of course, if you are availing any of the tax credits offered for Electrical Vehicle or Energy efficiency credits, etc. then you will be required to complete the relevant forms.
If you are using TurboTax rest assured that the program will guide you to complete your taxes accurately by asking simple question.
Hope this answers your question and thanks again,
