If you’ve ever tried to report your crypto taxes, you know how tricky it gets, especially when you’ve used multiple wallets. Tracking every swap, NFT trade, or staking reward across different blockchains can feel impossible. But the IRS expects you to get it right, down to the last transaction.
That’s where crypto tax software comes in. It helps you import your wallet data, calculate taxes accurately, and generate the forms you need to stay compliant. Whether you’re using MetaMask, Phantom, or a DeFi wallet, syncing your data properly is the first step.
In this guide, we’ll show you how to import your wallet data using different methods, avoiding common mistakes to make crypto tax season stress-free.
How Are Crypto Wallet Transactions Taxed In The USA?
The IRS treats digital assets as property, so actions like trading, earning rewards, or transferring assets can lead to capital gains or income tax obligations. It’s important to understand how each type of transaction may be taxed to stay compliant.
Capital Gains Events
Capital gains tax is applied when you dispose of or exchange crypto in a way that leads to a change in ownership or value. These wallet actions are usually considered capital disposals.
Capital Gains Events
Event | Description |
Crypto-To-Crypto Trades/Swaps | Swapping one crypto asset for another. The IRS treats this as a disposal. |
Providing Liquidity | Adding assets to a DeFi liquidity pool. Often considered a taxable transfer. |
Wrapping Tokens | Converting a token into its wrapped version (e.g., ETH to WETH). May be taxed. |
Bridging Tokens | Transferring assets across blockchains. This may trigger a capital event. |
Paying Gas Fees | Using crypto to pay network fees. Treated as spending and may result in a gain. |
Ordinary Income Events
Some wallet activities earn you crypto directly, and the IRS treats these earnings as ordinary income. You’re taxed based on the fair market value of the crypto at the time you receive it.
Income-Generating Wallet Events:
Event | Description |
Staking, Yield Farming, LP Rewards | Earning tokens for locking or lending assets. Taxed when received as income. |
Interest From Crypto Lending | Receiving interest from lending platforms. Taxed at the time of receipt. |
Non-Taxable Wallet Activities
Not every wallet transaction results in a tax event. Some actions are neutral and do not require reporting, although future events involving the same assets might.
Common Non-Taxable Actions:
Event | Description |
Borrowing Crypto | Taking out a loan in crypto doesn’t create taxable income or gains. |
Staking Crypto | Delegating assets for staking isn’t taxed. However, staking rewards are taxable. |

How to Import Your Wallet Data into A Crypto Tax Software?
A crypto tax software like KoinX gives you multiple ways to import wallet data depending on the type of wallet you use. Whether you’re working with a centralized exchange, a DeFi wallet, or a blockchain explorer, you’ll find a method that suits your setup. Let’s break down each option and how to use it effectively.
1. API Integrations
This method allows you to securely link your exchange accounts using API keys. Many crypto tax tools offer direct API integrations with major wallets like MetaMask, Solflare or MyEtherWallet. You can sync your wallet account to import all trades, deposits, and withdrawals automatically.
Steps to Import:
- In your crypto tax software, go to “Add Account” or “Connect Wallet.”
- Select your wallet name or the relevant blockchain (e.g., Ethereum, Solana).
- Copy your wallet’s public address from your wallet interface.
- Paste your address into the tax software.
- The platform will scan the blockchain and import all taxable events: trades, transfers, staking rewards, NFT sales, airdrops, yield farming, and more.
Repeat these steps for each address in your wallet to ensure full transaction coverage.
2. CSV File UPload
CSV uploads work well for wallets, exchanges, or platforms without API integration. You can manually export a CSV file from your wallet, blockchain explorer, or exchange, then upload it into the tax software.
Steps to Import:
- Go to your wallet or exchange and export your transaction history in CSV format.
- Once downloaded, select a good crypto tax software like KoinX and click “Sign-Up”
- In your crypto tax software, click “Add Wallet” or “Import CSV.”
- Select the correct wallet/blockchain name (e.g., Ethereum Wallet).
- Drag and drop the CSV file or use the upload browser.
- Ensure your CSV includes essential data:
- Date,
- Transaction type
- Token Quality and
- Transaction id
- Upload a separate CSV for each address or wallet if needed.
- The software will notify you of any missing fields or formatting issues.
Note: If you used a block explorer to download your CSV file, you’ll need to upload a separate CSV for each public address linked to your wallet. |
How To Generate Crypto Tax Report Using Wallet Integration?
Importing your wallet data correctly is key to generating accurate tax reports. Most crypto tax software simplify this process by offering multiple import options. Below is a step-by-step guide to help you connect your wallets and ensure your transaction history is complete before tax season.
1. Choose Your Crypto Tax Software
Start by selecting a crypto tax platform that supports your wallet type and complies with IRS rules. KoinX is a reliable option that integrates with 800+ wallets, exchanges, and DeFi platforms. It offers public address sync, CSV uploads, and powerful classification tools for all major blockchains like Ethereum, Solana, and Bitcoin, making it suitable for both casual and advanced users.
2. Create an Account
Once you’ve chosen your software, sign up and create an account. KoinX makes onboarding simple with a guided setup process. After logging in, you’ll be taken to your dashboard, where you can begin importing wallets or connecting exchanges. The platform also includes educational tooltips to help first-time users understand wallet syncing and categorizing their crypto activity.
3. Connect Wallets
KoinX allows you to import data using public addresses or by uploading CSV files. To connect a wallet, select “Add Wallet” from the dashboard, choose your blockchain (e.g., Ethereum), and paste your public address. The software will automatically fetch on-chain data including trades, airdrops, NFT sales, staking rewards, and transfers. Repeat this for each address you use within the same wallet.
4. Review and Categorize Transactions
Once the data is imported, KoinX will auto-classify most transactions. However, it’s important to review each entry. For example, staking rewards should be categorized as income, while NFT purchases may need manual adjustments. It also highlights any unclassified or unusual transactions so you can tag them correctly. This step is critical to ensure IRS-ready accuracy.
5. Add Missing Data
Some wallets or older platforms may not include cost basis or complete transaction histories. KoinX flags missing data and provides manual input options for transfers, deposits, or historical pricing. If you’ve moved assets between wallets, make sure to label them as internal transfers instead of sales to avoid inflating your taxable gains.
6. Generate Tax Report
Once everything looks accurate, you can generate your tax report. KoinX supports Form 8949, Schedule D, and other IRS-compliant formats. With one click, you’ll receive a full breakdown of capital gains, income, and losses for the year. You can also download reports as PDFs or spreadsheets for review with your tax professional.
Common Wallet Import Issues and How to Avoid Them?
Even with advanced crypto tax software, wallet data imports can sometimes lead to problems. Identifying and resolving these early can save you from inaccurate tax filings or compliance issues. Below are the most common problems users face, and how to avoid them.
Missing Transaction Data
One of the most common mistakes is forgetting to import data from all wallets or exchanges. Even rarely used wallets can contain taxable events. To avoid this, double-check that you’ve connected every public address and uploaded all CSV files, especially if you used multiple blockchains throughout the year.
Incorrect Cost Basis
Cost basis errors often happen when transfers between wallets aren’t properly matched. If the software can’t link the source of a token, it may treat the transfer as a taxable event. Make sure your software imports all transaction histories and correctly labels internal transfers to maintain an accurate cost basis.
DeFi and NFT Complexity
DeFi and NFT transactions are harder to categorize automatically. For example, yield farming might be misclassified as a simple transfer, or NFT mints might appear as outgoing transactions. Always review these manually. Tools like KoinX highlight uncertain events so you can correct them before finalizing your report.
Transaction Fees Not Logged
Gas or transaction fees paid using crypto can affect your capital gains calculations. If these aren’t logged properly, your taxable amounts may be overstated. Use software that automatically tracks fees from public blockchains and adjusts your cost basis accordingly.
API Connection Problems
API keys can expire, become restricted, or fail to fetch updated data. If your wallet data isn’t syncing correctly, try generating a new API key with read-only access and reconnect it. Always verify the most recent transactions are reflected in your imported history.
Duplicate Entries
Importing the same wallet via API and CSV can create duplicate transactions, inflating your gains or income. Avoid using multiple import methods for the same source. If needed, check for duplicates in the review step and delete them manually within your software.
Unsupported Chains or Platforms
New or niche blockchain networks might not be directly supported by your tax tool. In such cases, you’ll need to manually export a CSV from a blockchain explorer or the wallet itself, and upload it to the platform. KoinX provides templates to make this easier.
Shared Wallets
If multiple people use the same wallet, the software won’t know which transactions belong to whom. You’ll need to manually separate the activity and adjust the tax treatment accordingly. Use tagging features in your crypto tax tool to divide transactions if this applies to your case.
Prior Year Data Gaps
If this is your first time using crypto tax software, it’s essential to upload all historical transaction data, starting from your first crypto purchase. Without this, the tool can’t calculate cost basis accurately, which affects current year gains and losses. Always backfill your entire crypto history when getting started.

Frequently Asked Questions
Do I Need to Import Data from Every Wallet I’ve Used?
Yes. To ensure accurate tax calculations, you must import data from every wallet you’ve used, even for small or infrequent transactions. Missing wallets can lead to incorrect cost basis calculations and unreported gains, which could trigger IRS issues. Crypto tax tools like KoinX allow you to import multiple addresses to capture your complete transaction history.
Can I Import Wallet Data If I Only Use DeFi?
Absolutely. If you primarily use DeFi platforms, importing your public wallet address into crypto tax software allows the system to track all on-chain transactions. This includes swaps, staking, liquidity provision, NFT sales, and airdrops. Tools like KoinX are built to handle complex DeFi activities and will help classify them for capital gains and income tax purposes.
What Happens If a Transaction Is Missing or Incorrect?
If your imported wallet data has missing or misclassified transactions, most crypto tax software will flag them. You can then manually update the details or add missing entries. KoinX highlights inconsistencies and offers guided corrections, so you can ensure every transaction is reported correctly before generating your tax forms.
Is Wallet-to-Wallet Transfer Taxable?
No. Transferring crypto between your own wallets is not a taxable event. However, if the tax software cannot detect that both addresses belong to you, it might mistakenly mark it as a sale. To avoid this, ensure you import data from all your wallets. Platforms like KoinX can automatically identify internal transfers when full data is provided.
Do I Still Need to Import CSVs If I Use Public Address Sync?
Not always. Public address syncing captures most on-chain activity. However, for transactions from unsupported chains or older platforms, you may still need to upload CSVs. KoinX allows you to use both methods and even provides CSV templates for easier formatting. You should review the data after import to confirm that everything is complete.
