TaxHacker: Self-Hosted AI Accounting







 [!NOTE]
 ☝️ I'm currently looking for a job! Particularly interested in companies in Berlin or remote positions in Germany. Here's my CV and Linkedin profile. Thank you 🙏

TaxHacker is a self-hosted accounting app designed for freelancers, indie-hackers, and small businesses who want to save time and automate expense and income tracking using the power of modern AI.

Upload photos of receipts, invoices, or PDFs, and TaxHacker will automatically recognize and extract all the important data you need for accounting: product names, amounts, items, dates, merchants, taxes, and save it into a structured Excel-like database. You can even create custom fields with your own AI prompts to extract any specific information you need.

The app features automatic currency conversion (including crypto!) based on historical exchange rates from the transaction date. With built-in filtering, multi-project support, import/export capabilities, and custom categories, TaxHacker simplifies reporting and makes tax filing a bit easier.
