TaxHacker

TaxHacker is a local-AI tool - Self-hosted AI accounting app. LLM analyzer for receipts, invoices, transactions with custom prompts and categories.

Overview

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.

Snap a photo of any receipt or upload an invoice PDF, and TaxHacker will automatically recognize, extract, categorize, and store all the information in a structured database.

TaxHacker is open-source, written primarily in TypeScript, with 6,066 GitHub stars under the MIT license. The latest release is v0.7.0 (2026-04-03).
