Investment Tax Atlas

    Investment tax rarely turns on one rule.

    The result can depend on what happened, what you owned, how you acquired it, your basis, when you acted, how the transaction is reported, and which state has the right to tax it.

    The PRISM Investment Tax Atlas organizes those questions into a connected system—so you can start with the transaction in front of you and follow the tax consequences from there.

    Start with what happened

    You do not need to know the tax terminology first. Start with the situation you are trying to understand.

    Follow the tax chain

    Transaction → character → basis → timing → reporting → payment → state treatment

    A tax result can change at any point in that chain. The Atlas separates the questions so you can see which rule controls—and where another tax issue begins.
