Finance and accounting decision
Keeper Tax
Building a usable deduction-tracker and receipt workflow is realistic for a small team, but reproducing Keeper's patented deduction-tracking, IRS e-file authorization, and human-reviewed full-service filing is not practical to replace; keep paying for full-service features unless you only need a DIY tracker.

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Track deductible transactions, attach receipts, and export deductions for tax filing
What it still won’t have
- IRS authorized e-file provider status
- Keeper's patented deduction-tracking IP and any proprietary models
- Human tax pro review, 1:1 consultations, and audit protection
- Guaranteed accuracy and full-service filing (state+federal, complex forms)
- Year-round support and multi-year filing/amendments
What remains hard
- Proprietary models
Save thousands in taxes with Keeper's patented deduction tracking - recommended by accountants and trusted by tens of thousands of self-employed americans.
- Compliance and regulation

Runnable build prompt
Build a minimal deduction-tracking web app using React frontend, Node/Express backend, Postgres DB, and AWS hosting. Core features in scope: (1) Plaid integration to read transactions; (2) transaction classifier (rule-based + small ML model) that tags likely deductible items; (3) receipt upload endpoint with OCR (Tesseract or cloud OCR) and storage in S3; (4) dashboard to review/edit tagged deductions and export CSV of deductions; (5) user auth (JWT) and a Stripe subscription for payments. Out of scope: IRS e-filing, providing certified tax pro review, audit protection, multi-state/form filing. Include basic error handling, logging, unit tests for core logic (classification, upload, export), and a README with deployment steps.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
