Not that I know of. It would be difficult to make parachain-agnostic, since each can have its own pallets that handle assets. So it won’t be easy, but it would be possible to cover the majority of parachains and abstract out some of the individual features (and a valuable addition).
With such a standard in place, at least the tax part could be handled by https://rotki.com/ which has the benefit of running locally in an encrypted DB so your data does not end up in a thrid party DB.
I use https://www.accointing.com for my taxes. It supports scanning of the relay chains and some select para chains. They implement more parachains based on user feedback. It would be great if stuff could be implemented in an agnostic way for sure.
