About TaxHacker

TaxHacker is a self-hosted, LLM-powered accounting app aimed squarely at freelancers, indie hackers, and small businesses rather than at accounting firms. You upload receipts and invoices as photos or PDFs — individually or in bulk — and the model extracts dates, line items, vendors, and amounts, working across languages and tolerating poor photo quality, then files everything into a structured database. A built-in currency converter detects foreign currencies and converts them using the historical exchange rate for the transaction date, covering 170+ world currencies plus common cryptocurrencies such as BTC, ETH, and LTC, with manual override always available. Organization is deliberately unopinionated: you define your own categories, projects, and custom fields, filter by any column or date range, choose which columns the table shows, and import existing transactions from CSV. The feature that separates it from a generic receipt scanner is prompt-level control — you can edit the LLM prompts, define custom fields and tell the model how to populate them, and even ask it to score things like risk level, so the extraction schema matches whatever your jurisdiction or bookkeeper actually needs. An invoice generator produces invoices in any language with editable labels and titles, native handling of included and excluded taxes such as VAT and GST, PDF export, and reusable templates. Data portability is explicit: full-text search across documents, CSV export for tax prep, and a complete archive download for migration. It is an openly indie project, made in Berlin by @vas3k, and marked as under active development.
