🚀 What It Does

TaxFormatter turns messy financial exports into structured, tax-ready data — for humans and for AI agents.

Drop a CSV from Coinbase, a ZIP from Kraken, a .tar.gz from Binance, or a PDF statement from Chase, and get back a clean, normalized transaction set you can pipe into Koinly, TurboTax, CoinLedger, ZenLedger — or straight into your own software.

   Exchange CSV                        Clean, normalized
   Bank PDF              →             transactions (JSON / CSV)
   XLSX / ZIP / TAR.GZ                 + AI-generated insights

✨ Features

🔌 Developer REST API

Ship a crypto-tax or bank-ingestion feature into your product in an afternoon.

• POST /v1/parse — upload a CSV or PDF, get structured JSON back
• GET /v1/sources — list every supported exchange, bank, and output format, each with a verified / beta status
• GET /v1/usage — monthly quota, RPM limit, current consumption
• GET /v1/health — liveness probe
• Auth: X-API-Key header with tf_live_* keys (SHA-256 hashed at rest)
• Host: https://api.taxformatter.com

🤖 MCP Server for AI Agents

Give Claude, Cursor, Windsurf, or any MCP-compatible agent the ability to parse crypto and bank data directly.

npx @taxformatter/mcp-server

Tool	What it does
parse_crypto_csv	Auto-detects the exchange, returns normalized transactions
parse_bank_statement	Extracts transactions from bank statement PDFs
list_supported_sources	Queries every supported source + output format

📦 Official SDKs

• Node.js → @taxformatter/sdk — promise-based, fully typed
• Python → taxformatter — idiomatic, type-hinted

🏦 14 Exchanges · 6 Banks · 4 Export Formats

Every public supported-source claim is generated from two registries, and drift tests fail CI if any surface disagrees with them:

• Exchanges — backend/configs/exchanges.yaml, mirrored by lib/exchange-registry.ts
• Banks — backend/configs/banks/*.yaml, mirrored by lib/bank-registry.ts

GET /v1/sources serves the same lists. Every entry carries a status: verified means a fixture-backed parse test runs on every change; beta means the parser exists but has no fixture yet. A new status is earned by a test, never by editing a registry.

Exchanges (verified): Binance · Coinbase · Kraken · KuCoin · Bybit · Cash App · Robinhood · Crypto.com · Gemini · FTX · Bitfinex · OKX

Exchanges (beta): Venmo

Banks (verified): Chase · Mercury · Navy Federal

Banks (beta): Bank of America · Wells Fargo · Citi

Export formats: Koinly · TurboTax (Form 8949) · CoinLedger · ZenLedger

🧠 Tiered AI Insights

Every parsed file comes back with analysis scaled to your plan. Plans expose an insights level; the level → model mapping lives in lib/insights-engine.ts and is published only in the API docs and blog Updates posts.

Level	Plans	Output
Standard	Free / Starter	Quick stats + basic flagging
Advanced	Growth	Balanced analysis, breakdowns
Premium	Business	Deep analysis + tax suggestions

The insights contract is strict. Model output is validated against a fixed schema, and a refusal, truncation, or unparseable response falls back to the deterministic quick stats with an insights unavailable warning rather than partial flags. Every result is stamped with the model, prompt version, and effort that produced it, and every model call logs tokens, cache-hit rate, latency, and cost.

⚡ Quick Start

Run the web app

npm install
npm run dev

Open http://localhost:3000.

Try the API

curl -X POST https://api.taxformatter.com/v1/parse \
  -H "X-API-Key: tf_live_..." \
  -F "file=@coinbase.csv"

Use the MCP server with Claude Code

{
  "mcpServers": {
    "taxformatter": {
      "command": "npx",
      "args": ["@taxformatter/mcp-server"],
      "env": { "TAXFORMATTER_API_KEY": "tf_live_..." }
    }
  }
}

Install the Node SDK

npm install @taxformatter/sdk

import { TaxFormatter } from "@taxformatter/sdk";

const tf = new TaxFormatter(process.env.TF_API_KEY!);

// Parse a file by path, or pass a Buffer with a filename
const result = await tf.parse("./coinbase.csv");
const turbotax = await tf.parse(buffer, "coinbase.csv", { outputFormat: "turbotax" });

Install the Python SDK

pip install taxformatter

from taxformatter import TaxFormatter

tf = TaxFormatter("tf_live_...")
result = tf.parse("./coinbase.csv")

---

🧪 Testing

npm test              # Jest (700+ tests: API routes, MCP, keys, registries, UI)
npm run test:e2e      # Playwright end-to-end tests
npm run typecheck     # TypeScript strict mode
npm run lint          # ESLint
cd backend && pytest  # Python engine, parsers, insights, API Lambda (370+ tests)

Public copy is tested too. Drift guards under __tests__/ fail if any surface hard-codes a price, quota, or model name outside the registries, names an exchange or bank the registries don't list, or carries a superseded retention or marketing claim.

💳 Pricing

One plan, two ways to use it — drop a file in the dashboard or call our API. Same quota, same AI insights.

Tier	Price	Quota	RPM	AI Insights	Highlights
Free	$0	25 files	10	Standard	All exchanges · No credit card
Starter	$29/mo	100 files	30	Standard	All exchanges
Growth	$99/mo	500 files	60	Advanced	+ Bank PDF parsing
Business	$249/mo	2,000 files	120	Premium	+ Custom integrations

Source of truth: lib/tier-registry.ts (prices, quotas, limits) and lib/insights-engine.ts (which model serves each insights level). Model names are published in the API docs and blog Updates posts only.

🔒 Security Highlights

• API payloads never stored — request bodies are parsed in memory and never written to S3 or the database
• Metadata-only request log — api_requests stores key id, endpoint, status, bytes, timing, detected source, error code, and caller IP; never file contents
• API keys SHA-256 hashed at rest, prefixed tf_live_ for easy identification
• Uploads only — TaxFormatter never asks for exchange API keys or bank logins
• TLS 1.3 enforced everywhere
• AES-256 encryption on all stored uploads
• AWS WAF in front of the API
• 30-day retention — uploads, outputs, and parsed rows are deleted within 30 days (sooner from the dashboard); enforced by an S3 lifecycle rule and a daily prune cron
