What they did
In a Reddit discussion about simple personal taxes with rental income, one commenter said they let Claude control their PC and file the return after already handling an extension and submitting taxes the previous month. In a related reply, another user described watching the agent work through TurboTax page by page in a browser plugin on a wide monitor. They kept auditing the figures themselves and compared the results with other models and manual checks.
How it went
The commenter said the process worked extremely well, but gave no refund, speed, or accuracy figures for this run. They also noted that review turned up a few items that still needed attention.
Tips
This kind of setup still needs human oversight, especially for cross-checking numbers. Build in a hard stop before any submission or payment so you can review every field first.

Try it yourself with Claude computer use

Act as my tax-prep assistant using [tax software or website] on my PC. Work from the files in [folder path] and help me complete my [year] [country] return, including [income types, such as wages and rental income]. Fill the forms step by step and tell me which document each number came from. Before you type any login details, and again before any final submission or payment, stop and ask for my approval. If you see anything uncertain, flag it for review instead of guessing.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
