CoinTracker

CoinTracker is a cryptocurrency portfolio tracker and tax reporting platform. It integrates with 500+ exchanges and wallets, automatically tracks transactions, and generates IRS-compliant tax forms. CoinTracker is a Y Combinator-backed company used by millions of users.

CoinTracker solves the dual problem of portfolio management and tax compliance for crypto traders. It aggregates holdings across multiple exchanges and wallets into a single dashboard, calculates real-time unrealized gains and losses, and automatically converts transaction history into tax-ready reports. The platform handles the complexity of crypto taxation—including wash sale rules, staking rewards, DeFi swaps, and NFT sales—without requiring manual CSV uploads or spreadsheet calculations.

The core value lies in automation: CoinTracker connects directly to your exchange APIs and wallet addresses, pulling transaction data without you having to manually enter trades. It then categorizes each transaction (buys, sells, swaps, airdrops, staking rewards) and recalculates cost basis using your chosen accounting method. When tax season arrives, you have audit-ready reports ready to share with your accountant or import into TurboTax.

• Tax reporting: Generates IRS Form 8949 and Schedule D directly from your transaction history. Exports to TurboTax, integrates with accountant workflows, and provides documentation for every trade.
• Portfolio tracking: Real-time portfolio value, unrealized gains and losses, cost basis per holding, gain/loss by asset. Dashboard updates as prices move.
• Auto-sync: Direct API connections to 500+ exchanges and wallet addresses. Pulls transaction history automatically, no manual data entry.
• DeFi & NFTs: Tracks complex transactions including liquidity provision and withdrawal, yield farming, token swaps, Uniswap and other DEX trades, NFT purchases and sales, staking rewards, and governance tokens.
• Cost basis methods: Choose FIFO (first-in-first-out), LIFO (last-in-first-out), HIFO (highest-cost-first), or specific identification. Switch methods before filing to optimize tax outcome.
• Tax-loss harvesting: Identifies unrealized losses across your portfolio, highlighting opportunities to sell losing positions to offset gains and reduce tax liability.
• Accountant access: Generate shareable tax reports and grant read-only access to your accountant or tax professional without exposing API keys or exchange credentials.

CoinTracker serves traders across the spectrum:

• Day traders and swing traders who execute dozens of trades weekly need automatic transaction tracking to avoid manual reconciliation errors and meet IRS reporting deadlines.
• Active crypto traders managing positions across Binance, Kraken, Coinbase, and other exchanges use CoinTracker to consolidate holdings into one view and track performance across venues.
• DeFi participants executing swaps, providing liquidity, and farming yields rely on CoinTracker to categorize complex on-chain transactions that exchanges don't see.
• Crypto fund managers and advisors grant accountants access to client portfolios for audit and compliance without sharing private keys.
• Long-term holders use CoinTracker's cost basis tracking to minimize taxes on large positions sold over multiple tax years.

CoinTracker integrates directly with 500+ exchanges including Coinbase, Binance, Kraken, Gemini, and FTX. Wallet support includes MetaMask, Ledger, Coinbase Wallet, Trust Wallet, and hardware wallet addresses. Blockchain support spans Ethereum, Bitcoin, Solana, Polygon, Arbitrum, Optimism, and other major networks.

Scenario 1: Day Trader Tax Preparation You execute 150 trades across Binance and Coinbase during the year. CoinTracker auto-syncs both exchanges, categorizes each buy and sell, calculates gains/losses in real-time, and generates Schedule D and Form 8949 in minutes. You export to TurboTax or share the report with your accountant. Without CoinTracker, you would manually extract each trade from exchange CSV files, calculate cost basis by hand, and risk transcription errors that trigger IRS audits.

Scenario 2: DeFi Strategy Optimization with Tax Awareness You're running a liquidity-provision strategy on Uniswap and yield farming on Aave. CoinTracker tracks every swap, deposit, withdrawal, and reward claim—including impermanent loss and APY events—and labels them for tax purposes. When evaluating whether to exit a position, you see both the trading loss and the tax benefit of harvesting it, allowing you to make decisions that optimize after-tax returns.

Scenario 3: Multi-Year Position Management You bought Bitcoin in 2019, 2021, and 2023 at different prices. When you sell a portion in 2024, CoinTracker lets you choose specific-identification accounting to sell the highest-cost-basis batch first, minimizing capital gains. You track which purchases qualify for long-term capital gains treatment and which don't, ensuring you claim the tax rate that applies.

Scenario 4: Portfolio Rebalancing with Compliance You monitor your portfolio allocation across 10 holdings on five exchanges. CoinTracker's dashboard shows your total position in each asset and unrealized gain/loss. When you rebalance—selling winners to buy losers—CoinTracker logs the transaction, calculates the gain, and flags tax-loss harvesting opportunities in other positions to offset the gains.

StratBase.ai is a no-code backtesting platform that lets you design and test crypto trading strategies without code. CoinTracker complements backtesting in three ways:

Post-Backtest Execution Tracking: After you backtest a strategy on StratBase and deploy it live, CoinTracker automatically tracks every trade generated by the strategy across your exchanges. You see strategy performance in real-time, compare backtest results to actual execution, and spot slippage or fees that differ from simulation.

Tax-Adjusted Returns Analysis: A strategy can appear profitable in backtests but yield a lower after-tax return than expected. By connecting CoinTracker to your account, you track the actual tax liability incurred by the strategy in real time. This feedback loop helps you refine the strategy's entry and exit rules to optimize after-tax profit rather than gross profit.

Cost-Basis-Method Impact: Different accounting methods (FIFO, LIFO, HIFO) produce different tax outcomes for the same trades. CoinTracker lets you model each method and measure the tax cost of your StratBase strategy under each assumption. You can then adjust the strategy to favor HIFO-favorable exit patterns if advantageous.

Multi-Year Strategy Evaluation: Backtest results on StratBase show historical performance, but tax reporting on CoinTracker reveals the after-tax return once a strategy runs for a full year. Comparing both metrics ensures your strategy is profitable not just on paper, but in your after-tax pocket.
