Multi-Year Crypto Accounting I have complete CSV exports from every centralized exchange I used, along with wallet address histories, covering the calendar years 2022, 2023, 2024 and 2025. For transparency you can also pull the same data through the exchanges’ APIs, but I rely on the raw CSV files as the single source of truth. Your task is to turn those files into fully reconciled reports: • A year-by-year ledger that balances on-chain wallet activity with the matching exchange statements • Realised and unrealised gains/loss calculations, cost-basis tracking, end-of-year holdings and a concise P&L for each period • A final summary for each year that could be handed straight to a tax preparer. I am comfortable with whichever specialist tools you prefer—CoinTracking, Koinly, CoinLedger etc —so long as the end result is accurate and verifiable. Please outline briefly how you would approach the reconciliation (imports, matching logic, error handling) and any additional information you will need from me before you start. Accuracy is paramount; experience handling high-volume crypto data across wallets and CEX accounts is essential. If that sounds like your wheelhouse, I look forward to working together.

Hi, I have extensive experience reconciling multi-year cryptocurrency transactions and preparing fully verified reports suitable for tax and accounting purposes. I can take your CSV exports and on-chain wallet histories for 2022 2025 and produce reconciled ledgers, cost-basis tracking, realized and unrealized gains, end-of-year holdings, and concise P&L statements for each year. I would import your CSVs into a crypto accounting platform like CoinLedger or Koinly and validate all entries against your wallet histories to ensure every deposit, withdrawal, trade, and reward is captured. I then match on-chain wallet movements to exchange activity, resolving any discrepancies such as missing fees or transfer delays. I calculate realized and unrealized gains according to your preferred accounting method, verify end-of-year holdings against wallets and exchange statements, and generate clean, tax-ready summaries for each year, including P&L and detailed ledgers. Every transaction is reconciled, totals balance, and the cost basis is accurately tracked, with any errors documented and corrected. To get started, I would need the CSV exports for each exchange and wallet, your preferred cost-basis method, and any staking, DeFi, or lending income that should be included. I can start immediately and ensure accurate, verifiable reconciliations across all four years. Thanks and regards, Mussadiq Hussain

Which exchanges and wallets are involved, and do the CSVs include full transaction types like trades, deposits/withdrawals, staking, rewards, fees, and internal transfers for all years 2022–2025? Also, are there any missing records, chain bridges, airdrops, or token swaps that may need special treatment for cost-basis and reconciliation? This is exactly the kind of multi-year crypto accounting reconciliation I handle, and I can turn your raw CSVs into accurate, verifiable year-by-year reports with matching on-chain and CEX activity. I’ll work from the CSVs as source of truth, map transactions across wallets/exchanges, flag mismatches, and produce clean annual summaries for tax prep.

Navigating the complexities of multi-year crypto accounting requires meticulous reconciliation of diverse data sources to ensure every transaction aligns perfectly across wallets and exchanges. The critical challenge lies in harmonizing raw CSV exports with on-chain activity to produce transparent, audit-ready reports that accurately reflect realized and unrealized gains, cost basis, and year-end holdings. This project demands not only precision but also a deep understanding of crypto tax implications and the ability to present data in a format that is immediately usable by tax professionals. To tackle this, I will begin by importing all CSV files into a robust accounting platform such as CoinTracking or Koinly, depending on which offers the best integration for your data structure. The reconciliation process will involve algorithmic matching of wallet transactions with exchange statements, identifying discrepancies and resolving them through systematic error handling protocols. This includes cross-referencing timestamps, transaction hashes, and amounts to ensure every entry is accounted for accurately. I will generate detailed ledgers for each year, complete with comprehensive P&L summaries and cost-basis tracking that reflect both realized and unrealized gains, providing a clear and verifiable trail for tax purposes. Commitment to precision and clarity will guide the entire workflow, with regular progress updates and final reports formatted for seamless handoff to your tax preparer. Before starting, I will need access to your CSV files, any API credentials you are comfortable sharing for cross-verification, and clarification on any specific tax jurisdictions or reporting preferences. Let’s ensure your crypto accounting is thorough, transparent,
