Giving an agent a folder of your pay stubs / 1099s / everything for the year and telling it to “file my taxes for me” without all the messing about would be great.
I’m assuming with browser control it would already do a good job of this by driving turbo tax etc. but there’s probably a way to cut them out entirely.
Obviously you’d want to check it over, but 90% of the work for me is working around turbo tax jank / manually entering info when it fails to parse things or can’t auto link to an institution properly. An LLM steering a browser could easily do all that.
It's a bunch of PII that you'll be sending to the LLM provider. I'd be pretty uncomfortable with doing that even if it works.
I think it will be possible to do with the right harness in the future. I've tested gemma4 31b and it's pretty close with an engine backing it.
