Accurate Records, Zero Tax Liability

Why Crypto Bookkeeping Isn’t Optional for Crypto Users

Not every crypto transaction is taxable. So if you don’t have clean records, tracking your gains during tax season will become a complicated process. Unorganized records also imply that you’d be missing out on chances to build a good tax strategy with a crypto tax expert.

What’s taxable in crypto?

Some transactions create a tax bill even if you didn’t cash out to fiat:

Swapping tokens or coins
Selling crypto for USD or another currency
Earning staking rewards, yield, or interest
Receiving airdrops or mining income
Profiting from NFT sales

These taxable events need to be recorded with dates, cost basis, and market value. If your cryptocurrency bookkeeper misses that information, you could overpay taxes, or worse, underreport.

What’s not taxable in crypto?

Transferring assets between your own wallets
Holding crypto (no sale = no tax)
Gifting crypto (in some cases)

Even if it’s not taxable, your bookkeeper still needs to track these to keep your records audit-ready and your gains accurate.

Let’s clean up your crypto bookkeeping, so you can save time to focus on growing your crypto portfolio.

What we offer

Crypto Bookkeeping Services to Reconcile Your Traditional Bank Accounts and Crypto Wallets

Multi-Wallet & Multi-Chain Transaction Reconciliation

Manually tracking crypto activity across wallets, chains, and exchanges can cause messes in your records. We sync all your wallets and platforms to build an accurate ledger. When every transaction is matched and reconciled, you don’t have to worry about errors at tax time.

Crypto Bookkeeping

Our crypto bookkeepers handle day-to-day bookkeeping for both fiat and crypto transactions, giving you clear and updated financial records. Accurate crypto bookkeeping is important to understand your business’s financial health in terms of profit, losses, taxes, and cash flow. We integrate automated accounting tools so your records stay in sync. When all crypto transactions are reconciled and organized, it’s easier for you to manage financial risks and make informed business decisions.

DeFi and NFT Accounting

Short for decentralized finance, DeFi is the umbrella term for financial services like staking, lending, and liquidity pooling that occur directly on public blockchains like Ethereum. NFTs (non-fungible tokens) are also decentralized financial services that come with reporting challenges, especially when it comes to sales, royalties, and airdrops. Each type of transaction has its own tax treatment. Our team understands the nuances of DeFi protocols and NFT marketplaces. We categorize transactions correctly, calculate cost basis, and prepare audit-ready records tailored to IRS requirements whether you are farming yield or trading NFTs.

Crypto Mining Accounting

Mining crypto is one way to create a steady revenue stream. If you are a miner, you might be finding it hard to maintain your financial records while tracking block rewards, deducting equipment costs, and dealing with fluctuating income. At OCA, we guide solo and commercial miners to stay on top of the financial side. An experienced cryptocurrency accountant from our team will categorize income and capital expenses properly while managing electricity deductions and calculating depreciation.

Crypto Tax Reconciliation

If you have used multiple wallets, exchanges, or DeFi platforms, you know how chaotic crypto recordkeeping can get. CSV exports don’t always match, APIs drop data, and trades get lost in the shuffle. We take the stress out of reconciling your transactions. Firstly, our team pulls data from all your wallets, protocols, and platforms. Then every trade is matched, and any discrepancies are corrected. While crypto reconciliation is essential for a high-frequency trader before tax season, even if you are only active across a few chains, getting a clean financial picture is beneficial for crypto tax reporting.

CFO Services

Keeping your finances in order shouldn’t slow your project down. At OnChain, we give Web3 teams the structure and visibility they need to grow responsibly. Our crypto financial controllers handle core functions like monthly reporting, expense management, and treasury tracking with crypto-native precision. We help you make sense of on-chain activity, organize your books, and deliver clean financials that keep investors and stakeholders confident. To stay financially agile, our crypto accountants manage token incentives and protocol revenue as well as budgeting in stablecoins.

Our Process to Get You Expert Help From a Crypto CPA

Clean Books = Clear Tax Reporting

Without clean records, crypto tax filing becomes guesswork. This is definitely risky since the IRS expects accurate transaction histories that include details on cost basis, holding periods, and gain/loss calculations. With crypto bookkeeping services, your accountant won’t be left struggling to interpret missing data. When data is missing, you’ll be making financial decisions without the whole picture.

Strategy starts with accurate numbers.

A good financial strategy completely depends on knowing where you stand. This is especially true for the crypto market that moves fast. If your trades, protocol activity, and wallet balances aren’t properly tracked, you won’t know your real profit or loss. Clean books organized by a crypto bookkeeper give insights to make decisions such as selling or raising capital.

Avoid penalties with compliance.

QuickBooks and Xero are not meant to handle hundreds of on-chain transactions. Our crypto bookkeepers use crypto-native tools that integrate with your crypto activity more efficiently. This saves hours of manual work and reduces the risk of error.

Legacy tools weren’t built for crypto.

How Our Crypto Bookkeeping Process Works

Let’s customize a practical crypto accounting strategy that you can trust for your existing accounting system.

Establish a Dedicated Crypto Sub-Ledger Setup

First up, we’ll analyze your current accounting system and set up a crypto sub-ledger within it. This allows us to keep your digital asset transactions organized separately from your traditional financial activity. Your DeFi swaps will no longer mix with the office rent!

Custom Plan & Onboarding

Every client’s crypto use is different. You could be managing multiple wallets, operating a DeFi protocol, or handling NFT income. Let’s build a customized crypto accounting strategy that accounts for your specific transaction types and business operations. With this foundation set up right from the start, there are fewer chances for mistakes, especially in terms of categorization of crypto activity.

Implementation & Transaction Management

Our job isn’t done after the setup. We provide ongoing support, handling your monthly crypto bookkeeping, generating reports, and keeping you compliant. You’ll always have direct access to our crypto tax experts for questions, updates, and year-end tax preparation.

Ongoing Reconciliation & Monthly Reporting

To maintain accuracy and compliance, we reconcile your crypto records with your main ledger on a monthly basis. You'll also receive regular financial reports, including profit and loss statements, balance sheets, and gain/loss summaries to support strategic decision-making.
