Let an agent fill in your Swiss tax declaration
Agents classified the author's documents, put figures into a Google Sheet, then operated the Swiss tax form in the browser and found two items that reduce tax; the author double-checked.
Done with a custom-built or unnamed agent
- What they did
- The author told agents where his documents were. They sorted them into folders and put the relevant figures into a Google Sheet. After a trial run downloading bank documents with a Record & Replay skill, he let an agent work the tax form in his browser while he watched. It entered figures, saved progress, added comments, and bundled supporting PDFs per section.
- How it went
- It filled the forms, including the tedious assets section, and found two new tax-reducing items. About 95% of the PDF grouping was right. He found a few small errors to correct, and overall it was not faster.
- Worth knowing
- He needed ChatGPT's $100 plan and used a week's allowance in two days. He estimates the run cost about $25, and he still checked everything repeatedly.

Then fill in the tax form in my browser from that sheet and tell me about any deductions I may have missed. I will log in myself, and you must stop and show me the filled form before you submit anything.
