## What it does

The skill classifies Solana transactions by tax treatment: Jupiter swaps, liquidity pool deposits and withdrawals, staking rewards, airdrops, token migrations. Failed transactions get dropped from the export, since no taxable event happened there.

Output comes in the column layout each tax tool expects — Koinly, CoinTracker, CoinLedger, TokenTax each have their own labels and fields, plus a simplified format for TurboTax and TaxAct. It also builds IRS Form 8949 with Part I and Part II and columns a through h. Cost basis runs on FIFO, LIFO, HIFO or specific identification. A reconciliation pass matches on-chain history against your trade journal and flags missing entries, duplicates and amount mismatches.

You need Python 3.10 and trade data from a journal, exchange export or on-chain history. On-chain reconciliation calls for Solana RPC or Helius API access; historical prices come from Birdeye or CoinGecko. The skill formats data and does the math only. It is not tax advice, so run the numbers past a qualified professional before filing.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill crypto-tax-export -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/crypto-tax-export/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/crypto-tax-export/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill crypto-tax-export -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/crypto-tax-export/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill crypto-tax-export -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/crypto-tax-export/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**

```

2. **Platform CLI**
```bash
gemini skills install https://github.com/agiprolabs/claude-trading-skills --path skills/crypto-tax-export
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/crypto-tax-export/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill crypto-tax-export -a opencode
```

### Claude.ai

**Claude.ai**

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/agiprolabs/claude-trading-skills/tree/HEAD/skills/crypto-tax-export/SKILL.md

## When to use it
- export trades as a CSV Koinly will accept
- sort Jupiter swaps and LP operations into tax categories
- compute cost basis with HIFO and produce Form 8949
- reconcile on-chain history against a trade journal and find gaps
- keep failed transactions out of the tax report

## Example prompts
- export my 2025 trades in Koinly format
- compute cost basis with HIFO and build IRS Form 8949
- reconcile my Solana on-chain history with the trade journal and show mismatches

# Crypto Tax Export

Export trade history and tax calculations for tax software and IRS filing. Handles Solana-specific transaction types (Jupiter swaps, LP operations, staking rewards, airdrops) and generates CSVs compatible with Koinly, CoinTracker, CoinLedger, TokenTax, TurboTax/TaxAct, and IRS Form 8949.

> **Disclaimer:** This skill provides data formatting and calculation tools only. It does not constitute tax advice. Consult a qualified tax professional for guidance on reporting cryptocurrency transactions. Tax laws vary by jurisdiction and change frequently.

## Prerequisites

- Python 3.10+
- Trade history data (from internal trade journal, on-chain history, or exchange exports)
- For on-chain reconciliation: Solana RPC or Helius API access (see `helius-api` skill)
- For cost basis: historical price data (see `birdeye-api` or `coingecko-api` skills)

## Capabilities

| Capability | Description |
|---|---|
| Multi-format CSV export | Koinly, CoinTracker, CoinLedger, TokenTax, TurboTax, TaxAct |
| IRS Form 8949 generation | Part I (short-term) and Part II (long-term), columns a through h |
| Solana tx classification | Jupiter swaps, multi-hop routes, LP deposits/withdrawals, staking, airdrops |
| Cost basis methods | FIFO, LIFO, HIFO, Specific Identification |
| Reconciliation | Match on-chain history against internal trade journal |
| Failed tx handling | Identify and exclude failed transactions (no taxable event) |

## Supported Export Formats

### Koinly CSV

Koinly expects a universal import format with these columns:

```
Date,Sent Amount,Sent Currency,Received Amount,Received Currency,Fee Amount,Fee Currency,Net Worth Amount,Net Worth Currency,Label,Description,TxHash
```

Labels: `swap`, `staking`, `airdrop`, `liquidity_in`, `liquidity_out`, `cost`, `gift`, `lost`.

### CoinTracker CSV

```
Date,Received Quantity,Received Currency,Sent Quantity,Sent Currency,Fee Amount,Fee Currency,Tag
```

Tags: `trade`, `staking_reward`, `airdrop`, `lp_deposit`, `lp_withdrawal`.

### CoinLedger CSV

```
Date (UTC),Type,Received Currency,Received Amount,Sent Currency,Sent Amount,Fee Currency,Fee Amount,Exchange/Wallet
```

Types: `Trade`, `Income`, `Gift Received`, `Mining`, `Staking Reward`, `Airdrop`.

### TokenTax CSV
