Tax figures ready for the accountant
u/floraldo had Claude Code read 3 bank accounts almost 2 years back, match receipts from email and make reports in the tax authority's boxes. He sent 19 questions to the accountant. He writes that the advice has saved 1000s of euros. Filing is not confirmed.

What was done
On 19 April 2026 u/floraldo writes in r/ClaudeCode that he was almost 2 years behind on Dutch tax. Claude Code was used for a system that reads transactions from 3 bank accounts, 2 years back, fetches receipts from email, categorises, works out what he owes, to whom and by when, and makes reports ready for the accountant. The format follows the tax authority's boxes. The next quarterly report should, he writes, be one command and take 5 minutes. A knowledge base has WBSO, innovatiebox and holding, gathered after Claude did research on his case. He can ask strategy questions with the rules and his figures. He writes that it has already saved him 1000s of euros. Unclear points become questions for the accountant. The email he sent had 19 questions. The reply is to be read into the base when it comes.
How it went
The reports are ready for the accountant, and 19 questions have been sent. He has not written that the return was filed. The accountant had not replied in the post.
Worth knowing
"1000s of euros" is not an exact amount. The 3 accounts are not named. "Almost 2 years" are his words. Check the original. This is not tax advice. The model does not file the return.
How to do it
- Let transactions and receipts be read in and categorised as a draft.
- Read what the system thinks you owe, and which points are unclear.
- Send the questions to the accountant yourself. Do not file the return before you have said yes.
Try it with Claude Code
Read transactions from [accounts] and receipts in [inbox] for [period]. Categorise and list what belongs in which boxes, and which questions must go to the accountant. Do not file the return and do not send it until I say yes.
Replace text in brackets with your own.
Done when. You have a list of questions, and the return has not been filed.
Safety rule. The agent does not file the return. You say yes before anything is sent to the authority.
